The First 1000 Miles (1500km)

The more cautiously you treat your
vehicle during the break-in period, the
more satisfied you will be with its
performance later on. Therefore, drive
your vehicle during the first 1000 miles
(1500 km) at moderate vehicle and
engine speeds.

During this period, avoid heavy loads
(full throttle driving) and excessive
engine speeds.

Avoid accelerating by kickdown. It is
not recommended to brake the vehicle
by manually shifting to a lower gear.
We recommend to select positions "3",
"2" or "1" only at moderate speeds (for
hill driving).

After 1000 miles (1500 km) speeds
may be gradually increased to the
permissible maximum.

Check Regularly and Before a Long
Trip

Catalytic Converter

Caution!

Warning!

Your MERCEDES-BENZ is equipped
with monolithic type catalytic converters,
an important element in conjunction with
the oxygen sensor to achieve substantial
control of the pollutants in the exhaust
emissions. Keep your vehicle in proper
operating condition by following our re­commended maintenance instructions as
outlined in your Maintenance Booklet.

To prevent damage to the catalytic
converters, use only premium unleaded
gasoline in this vehicle.

Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter
causing it to overheat.

As with any vehicle, do not idle, park
or operate this vehicle in areas where
combustible materials such as grass,
hay or leaves can come into contact
with the hot exhaust system, as these
materials could be ignited.

Starting and Turning off the Engine

Cold Engine

Important!

Starter Lock-Out

Important!

The engine can only be started, if the
vehicle was unlocked from the outside.

Before Starting

Engage parking brake and ensure
gearshift lever is in neutral (selector
lever position "P" or "N" on automatic
transmissions).
Turn key in steering lock to position 2.
The charge indicator lamp should come
on.

Note:
If transmit button of the remote control
is inadvertently pressed again prior to
starting the engine, the start lock-out is
activated. In this case press transmit
button again to deactivate the start
lockout.

Do not depress accelerator.
Turn key in steering lock clock-wise to
the stop. Do not depress accelerator.
Release key only when the engine is
firing regularly.

Hot Engine

Do not depress accelerator. Turn key in
steering lock clock-wise to the stop. If
the engine has not fired after approx. 4
seconds, depress accelerator and
continue cranking until the engine is
firing regularly. Release key and back
off accelerator.
At very high coolant temperatures the
engine starting time can be shortened if
the accelerator is depressed slowly at
the beginning of the starting process.

Turning Off

Turn the key in the steering lock to
position 0 to stop the engine.

The key can only be removed with the
selector lever in position

"P".

Due to the installed starter non-repeat
feature, the key must be turned
completely to the left before attempting
to start the engine again.

Observe the oil pressure gauge
immediately after starting the engine.
In a very cold engine the oil pressure
will rise slowly after the engine has
started. Do not speed up the engine
before pressure is registered on the
pressure gauge. If you do not see the
gauge register oil pressure, stop the
engine and have it checked.

The battery charge indicator lamp
should go out as soon as the engine has
started.

In areas where temperatures frequently
drop below -4°F (-20°C) we
recommend that an engine block heater
be installed. Your authorized
Mercedes-Benz dealer will advise you
on this subject.

15

Driving Instructions

Warning!

If you feel a sudden significant
vibration or ride disturbance, or you
suspect that possible damage to your
vehicle has occurred, you should
turn on the hazard flashers, carefully
slow down, and drive with caution to
an area which is a safe distance from
the roadway.
Inspect the tires and under the
vehicle for possible damage. If the
vehicle or tires appear unsafe, have it
towed to the nearest Mercedes-Benz
or tire dealer for repairs.

Power Assistance

Warning!

When the engine is not running, the
brake and steering systems are
without power assistance. Under
these circumstances, a much greater
effort is necessary to stop or steer the
vehicle.

Brakes

Warning!

After driving in heavy rain for some
time without applying the brakes or
through water deep enough to wet
brake components, the first braking
action may be somewhat reduced
and increased pedal pressure may be
necessary. Be sure to maintain a safe
distance from vehicles in front.
Resting your foot on the brake pedal
will cause excessive and premature
wear of the brake pads.
It can also result in the brakes
overheating thereby significantly
reducing their effectiveness. It may
not be possible to stop the car in
sufficient time to avoid an accident.

The condition of the parking brake
system is checked each time the car is
in the shop for the required
maintenance.

All checks and maintenance work on
the brake system should be carried out
by an authorized Mercedes-Benz
dealer.

If the parking brake is released and the
brake warning lamp in the instrument
cluster stays on, the brake fluid level in
the reservoir is too low.
Brake pad wear or a leak in the system
may be the reason for low brake fluid
in the reservoir.

Have the brake system inspected at an
authorized Mercedes-Benz dealer
immediately.

Install only brake pads and brake fluid
recommended by Mercedes-Benz.

Warning!

If other than recommended brake
pads are installed, or other than
recommended brake fluid is used,
the braking properties of the vehicle
can be degraded to an extent that
safe braking is substantially
impaired.

16

Caution!

When driving down long and steep
grades, relieve the load on the brakes
by shifting into "3", "2" or "1" (for
models SL 500 and SL 600). This helps
prevent overheating of the brakes and
reduces brake pad wear.

After hard braking, it is advisable to
drive on for some time, rather than
immediately parking, so the air
stream will cool down the brakes
faster.

Tires

Tread wear indicators (TWI) are
required by law. These indicators are
located in six places on the tread
circumference and become visible at a
depth of approximately

1

/16in (2 mm),
at which point the tire is considered
worn and should be replaced.
The tread wear indicator appears as a
solid band across the tread.

Warning!

Do not allow your tires to wear
down too far. With less than

1

/16in
(1.5 mm) of tread, the adhesion
properties on a wet road are sharply
reduced.
Depending upon the weather and/or
road surface (conditions), the tire
traction varies widely.

Specified tire pressures must be
maintained. This applies particularly if
the tires are subjected to high loads
(e.g. high speeds, heavy loads, high
ambient temperatures).

Warning!

Do not drive with a flat tire. A flat
tire affects the ability to steer or
brake the vehicle. You may lose
control of the car. Continued driving
with a flat tire or driving at high
speed with a flat tire will cause
excessive heat build-up and possibly
a fire.

Aquaplaning

Depending on the depth of the water
layer on the road, aquaplaning may
occur, even at low speeds and with
new tires. Avoid track grooves in the
road and apply brakes cautiously in the
rain.

17

Tire Traction

Tire Speed Rating

Parking

The safe speed on a wet, snow covered
or icy road is always lower than on a
dry road.
You should pay particular attention to
the condition of the road as soon as the
prevailing temperatures fall close to the
freezing point.

Warning!

If ice has formed on the road, tire
traction will be substantially
reduced. Under such weather
conditions, drive, steer and brake
with extreme caution.

We recommend M + S radial-ply tires
for the winter season for all four wheels
to insure normal balanced handling
characteristics.
On packed snow, they can reduce your
stopping distance as compared with
summer tires. Stopping distance,
however, is still considerably greater
than when the road is wet or dry.

Your vehicle is factory equipped with
"Z"-rated tires.

Despite the tire rating, local speed
limits should be obeyed. Use prudent
driving speeds appropriate to
prevailing conditions.

Warning!

Even when permitted by law, never
operate a vehicle at speeds greater
than the maximum speed rating of
the tires.

Exceeding the maximum speed for
which tires are rated can lead to
sudden tire failure causing loss of
vehicle control and resulting in
personal injury and possible death.

Warning!

To reduce the risk of personal injury
as a result of vehicle movement,

turning off the engine and

before
leaving the vehicle always:

1. Keep foot on brake pedal.

2. Firmly depress parking
brake pedal.

3. Engage first or reverse gear
(selector lever position "P" in the
case of automatic transmissions).

4. Slowly release brake pedal.

5. Turn front wheels towards
the road curb.

6. Turn the key to steering
lock position 0 and remove.

Important!

It is advisable to set the parking brake
whenever parking or leaving the
vehicle. In addition, engage first or
reverse gear (selector lever position
"P").
When parking on hills, always set the
parking brake.

18

Winter Driving Instructions

The most important rule for slippery or
icy roads is to drive sensibly and to
avoid abrupt acceleration, braking and
steering action. Do not use the cruise
control system under such conditions.

When the vehicle is in danger of
skidding, declutch, or in case of
automatic transmission move selector
lever to position "N". Try to keep the
vehicle under control by corrective
steering action.
Road salts and chemicals can adversely
affect braking efficiency. Increased
pedal force may become necessary to
produce the normal brake effect. We
therefore recommend depressing the
brake pedal periodically when traveling
at length on salt-strewn roads. This can
bring road salt impaired braking
efficiency back to normal.
A prerequisite is, however, that this is
done without endangering other drivers
on the road.

If the vehicle is parked after being
driven on salt treated roads, the braking
efficiency should be tested as soon as
possible after driving is resumed while
observing the safety rules in the
previous paragraph.

Warning!

If the vehicle becomes stuck in snow,
make sure that snow is kept clear of
the exhaust pipe and from around
the vehicle with engine running.
Otherwise, deadly carbon monoxide
(CO) gases may enter vehicle interior
resulting in unconsciousness and
death.
To assure sufficient fresh air
ventilation, open a window slightly
on the side of the car that is out of
the wind.

Passenger Compartment

Warning!

Always fasten items being carried as
securely as possible.
In an accident, during hard braking
or sudden maneuvers, loose items
will be thrown around inside the
vehicle, and cause injury to vehicle
occupants unless the items are
securely fastened in the vehicle.

increasing cooling capacity.

The automatic climate control removes
considerable moisture from the air
during operation in the cooling mode.
It is normal for water to drip on the
ground through ducts in the underbody.

Note:
Keep the air intake grille in front of
windshield free of snow and debris.

Dust Filter

Dust particles (down to a certain size)
and pollen are filtered out before
outside air enters the passenger
compartment through the air
distribution system.

Important!

This vehicle is equipped with an air
conditioner system that uses HFC-134a
(ozone-friendly hydro-fluorocarbon) as
a refrigerant.

Repairs should always be performed
by a qualified technician, and
refrigerant should be collected in a
recovery system for recycling.

1. Temperature Selector

Select the desired temperature with the

flash and the horn will sound
intermittently when someone:

• opens a door,

• opens the trunk,

• opens the hood,

• removes the radio,

• switches on or bridges the

ignition circuit,

• steps on the brake pedal,

• opens the storage compartment

between the front seats,

The alarm will last approximately 150
seconds in the form of blinking exterior
lamps. At the same time an alarm horn
will sound intermittently for 60
seconds, pause for 30 seconds, and
repeat for another 60 seconds.

The alarm will stay on even if the

Seat Belts and Supplemental
Restraint System (SRS)

Your vehicle is equipped with lap­shoulder seat belts, emergency
tensioning retractors for the seat belts,
driver airbag and knee bolster and
passenger airbag and knee bolster.

Seat Belts

Important!

Laws in most states and all Canadian
provinces require seat belt use.

All states and provinces require use of
child restraints that comply with U.S.
Federal Motor Vehicle Safety Standard
213 and Canadian Motor Vehicle
Safety Standard 213.1. We strongly
recommend their use.

Seat Belt Warning System

With the key in steering lock
position 2, an audible warning sounds
for a short time if the driver's seat belt
is not fastened.

Warning!

Failure to wear and properly fasten
and position your seat belt greatly
increases your risk of injuries and
their likely severity in an accident.
You and your passengers should
always wear seat belts.
If you are ever in an accident, your
injuries can be considerably more
severe without your seat belt
properly buckled. Without your seat
belt buckled, you can hit the interior
of the vehicle or be ejected from it.
You can be seriously injured or
killed.

In the same crash, the possibility for
injury or death is lessened with your
seat belt buckled.

The seat belts provide protection
only with the backrest locked in
place. If the seat belt warning lamp
does not go out, but is instead lit con­tinuously, then a backrest is not
engaged in its lock.

Never ride in a moving vehicle with
the seat back reclined. Sitting in an
excessively reclined position can be
dangerous. You could slide under the
seat belt in a collision. If you slide
under it, the belt would apply force
at the abdomen or neck. That could
cause serious or even fatal injuries.
The seat back and seat belts provide
the best restraint when the wearer is
in an upright position and belts are
properly positioned on the body.

40

Press switch (4) to adjust seat belt so
that the shoulder portion is located as
close as possible to the middle of your
shoulder.
The shoulder portion of the seat belt
must be pulled snug and checked for
snugness immediately after engaging it
and during driving. Tighten the lap
portion to a snug fit by pulling
shoulder portion up.

2. Buckle

3. Release button

Fastening of Seat Belts

Pull belt with latch plate (1) across
shoulder and lap. Push latch plate (1)
into buckle (2) until it clicks. The lap
belt should be positioned as low as
possible on your hips and not across
the abdomen. Do not twist the belt. A
twisted seat belt may cause injury.
For safety reasons, avoid adjusting the
seat or seat back into positions which
could affect the correct seat belt
position.

41

Unfastening of Seat Belts

Push in the red button (3) in the belt
buckle (2).

Allow the retractor to completely
rewind the seat belt by guiding the
latch plate (1).

Operation:
The inertia reel stops the belt from
unwinding during sudden vehicle stops
or when quickly pulling on the belt.

The locking function of the reel may be
checked by quickly pulling on the belt.

The emergency tensioning retract-ors
tighten the fastened seat belts during
frontal and front-angled impacts
exceeding the first threshold of the
SRS (see Index).

Note:
For cleaning and care of the seat belts,
see Cleaning and Care of the Vehicle
in Index.

Warning!

USE SEAT BELTS PROPERLY.

• Each occupant should wear
their seat belt at all times,
because seat belts help re
duce the likelihood of and
potential severity of injuries
in accidents, including roll­overs. "SRS" (driver airbag,
passenger airbag), "ETR"
(seat belt emergency tensioning
retractors), and knee bolsters
are designed to enhance the
protection offered to properly
belted occupants in certain
frontal impacts which exceed
preset deployment thresholds.

• Improperly positioned seat

belts do not provide maxi
mum protection and may
cause serious injuries in
case of an accident.

In a crash, your body would
move too far forward. That
would increase the chance of
head and neck injuries. The belt
would also apply top much force
to the ribs, which could severely
injure internal organs such as
your liver or spleen.

• Position the lap belt as low
as possible on your hips
and not across the
abdomen. If the belt is
positioned across your
abdomen, it could cause
serious injuries in a crash.

be used for more than one
person at a time. Do not
fasten a seat belt around a
person and objects.

• Belts should not be worn
twisted. In a crash, you
wouldn't have the full width
of the belt to take impact
forces. The twisted belt
against your body could
cause injuries.

• Pregnant women should
also use a lap-shoulder belt.
The lap belt portion should
be positioned as low as
possible on the hips to
avoid any possible pressure
on the abdomen.

USE CHILD RESTRAINTS
PROPERLY.

• Infants and small children
must be seated in an infant
or child restraint system,
which is properly secured
by a lap belt or lap belt
portion of a lap-shoulder
belt. Children could be en
dangered in an accident if
their child restraints are not
properly secured in the
vehicle.

• Rear-facing child restraints
must not be used in the
front seat. They could be
struck by the airbag when it
inflates in a crash. If this
happens, a child in the
restraint could be seriously
injured.

• Children too big for child
restraint systems should
use regular seat belts.
Position shoulder belt
across chest and shoulder,
not face or neck. A booster
seat may be necessary to
achieve proper belt
positioning.

43

Supplemental Restraint System
(SRS)

The SRS uses two crash severity levels
(thresholds) to activate either the ETR
or airbag or both. Activation depends
on the direction and severity of the
impact, exceeding the thresholds and
fastening of the seat belt.

Emergency Tensioning
Retractor (ETR)

The seat belts are equipped with
emergency tensioning retractors. These
tensioning retractors are located in each
belt's inertia reel and become
operationally ready with the key in
steering lock position 1 or 2.

In cases of other frontal impacts, roll­overs, certain side impacts, rear
collisions, or other accidents without
frontal forces, the emergency
tensioning retractors will not be
activated. The driver and passenger
will then be protected by the fastened
seat belts and inertia reel in the usual
manner.

Seat belt fastened

• first threshold exceeded:
ETR activates

• second threshold exceeded:
airbag also activates

Seat belt not fastened

• first threshold exceeded:
airbag activates, but not ETR

Driver and front passenger systems
operate independently from each other.

The emergency tensioning retractors
are designed to activate only when the
seat belts are fastened during frontal
and front-angled impacts exceeding the
first threshold of the SRS. They
remove slack from the belts in such a
way that the seat belts fit more snugly
against the body, restricting its forward
movement as much as possible.

For seat belt and emergency tensioning
retractor safety guidelines, see Safety
Guidelines in Index.

44

Airbags

1. Driver airbag

2. Front passenger airbag

3. Side impact airbag

The most effective occupant restraint
system yet developed for use in
production vehicles is the seat belt. In
some cases, however, the protective
effect of a seat belt can be further
enhanced by an airbag.

The driver airbag is located in the
steering wheel hub. The passenger
airbag is located in the dashboard
ahead of the passenger.

The side impact airbags are located in
the doors. In conjunction with wearing
the seat belts with emergency
tensioning retractors, the airbags can
provide increased protection for the
driver and passenger in certain major
frontal and front-angled and side
impacts.

The operational readiness of the
airbag system is verified by the
indicator lamp "SRS" in the
instrument cluster. If no fault is
detected, the lamp will go out after
approximately 4 seconds; after the lamp
goes out, the system continues to
monitor the components and circuitry
of the airbag system

and will indicate a malfunction by
corning on again.
The following system components are
monitored or undergo a self-check:
crash-sensor, airbag ignition circuits,
driver and passenger seat belt buckles.
Initially, when the key is turned from
steering lock position 0 to positions 1
or 2, malfunctions in the crash-sensor
are detected and indicated (the "SRS"
indicator lamp stays on longer than 4
seconds).

In the operational mode, after the
indicator lamp has gone out
following the initial check, inter­ruptions and short circuits in the

45

airbag ignition circuit and in the driver
and passenger seat belt buckle
harnesses, and low voltage in the entire
system are detected and indicated.
In the event a malfunction of the "SRS"
is indicated as outlined above, the
"SRS" may not be operational. We
strongly recommend that you visit an
authorized Mercedes-Benz dealer
immediately to have the system
checked; otherwise the "SRS" may not
be activated when needed.

Front Airbags

The driver and passenger front "SRS"
airbags are designed to activate only in
certain frontal and front-angled
impacts.
Both airbags may deploy, even if the
passenger seat is unoccupied.

Side Airbags

The side impact "SRS" airbags are
designed to activate only in certain side
impacts. Only the impacted side airbag
deploys.

Important!

The airbags are designed to activate
only in certain frontal and front­angled impacts. Only during these
types of impacts will they provide
their supplemental protection. The
driver and passenger should always
wear the seat belts, otherwise it is not
possible for the airbags to provide
their intended supplemental
protection.

In cases of other frontal impacts,
roll-overs, certain side impacts, rear
collisions, or other accidents without
frontal forces, the airbags will not be
activated. The driver and passenger
will then be protected by the
fastened seat belts.

We caution you not to rely on the
presence of an airbag in order to
avoid wearing your seat belt.

Important!

The "SRS" is designed to reduce the
potential of injury in certain frontal
and front-angled impacts which may
cause injuries, however, no system
available today can totally eliminate
injuries and fatalities.

The activation of the "SRS"
temporarily releases a small amount
of dust from the air-bags. This dust,
however, is neither injurious to your
health, nor does it indicate a fire in
the vehicle.

The service life of the airbags
extends to the date indicated on the
label located on the driver-side door
latch post. To provide continued
reliability after that date, they
should be inspected by an authorized
Mercedes-Benz dealer at that time
and replaced when necessary.

The passenger side impact airbag may
deploy, even if the seat is unoccupied.

Warning!

It is very important for your safety to
always be in a properly seated
position and to wear your seat belt.

For maximum protection in the event
of a collision always be in normal
seated position with your back
against the seat back. Fasten your
seat belt and ensure that it is
properly positioned on the body.

Since the airbag inflates with
considerable speed and force, a
proper seating position will keep you
in a safe distance from the airbag:

• Sit properly belted in an
upright position with your
back against the seat back.

• Do not lean with your head
or chest close to the steering
wheel or dashboard.

• Infants and small children
should only be seated in an
infant or child restraint
which is properly secured
by the seat belt.

• Rear-facing child restraints
must not be used in a front
seat.

Failure to follow these instructions
can result in severe injuries to you or
other occupants.

For unobstructive inflation of side
airbags, keep door pock-et lids
closed.

• Adjust the driver seat as far
as possible rearward, still
permitting proper operation
of vehicle controls.

• Adjust the passenger seat
as far as possible rearward
from the dashboard,
especially when a child
restraint is installed.

Safety Guidelines for the Seat Belt,
Emergency Tensioning Retractor
and Airbag

Warning!

• Damaged belts or belts that
were highly stressed in an
accident must be replaced and
their anchoring points must also
be checked. Use only belts
installed or supplied by an
authorized Mercedes-Benz
dealer.

• Do not pass belts over sharp
edges.

• Do not make any modification
that could change the
effectiveness of the belts.

• The "SRS" is designed to
function on a one-time-only
basis. An airbag or emergency
tensioning retractor (ETR) that
was activated must be replaced.

• No modifications of any kind
may be made to any components
or wiring of the "SRS". This
includes the installation of
additional trim material, badges
etc. over the steering wheel hub
or front passenger airbag cover
and installation of additional
electrical/electronic equipment
on or near "SRS" components
and wiring.

• Several airbag system com­ponents at the steering wheel get
hot after the air-bag has inflated.
Don't try to touch them.

• Improper work on the system,
including incorrect installation
and removal, can lead to possible
injury through an uncontrolled
activation of the "SRS".

• In addition, through improper
work there is the risk of
rendering the "SRS"
inoperative. Work on the "SRS"
must therefore only be
performed by an authorized
Mercedes-Benz dealer.

• When scrapping the airbag unit
or emergency tensioning
retractor, it is mandatory to
follow our safety instructions.
These instructions are available
at your authorized Mercedes­Benz dealer.

When you sell the vehicle we strongly
urge you to give notice to the
subsequent owner that it is equipped
with an "SRS" by alerting him to the
applicable section in the Owner's
Manual.

Infants and Child Restraint
Systems

We recommend that all infants and
children be restrained at all times while
the vehicle is in motion.
The passenger seat has a special seat
belt retractor for secure fastening of a
child restraint. To use, fasten child
restraint with seat belt: Follow child
restraint instructions for routing. Then
pull shoulder belt out completely. Slide
switch located on side of passenger seat
to position . Let the belt retract. It
is now locked. Push down on child
restraint to take up any slack.

Important!

The use of infant or child restraints is
required by law in all 50 states and all
Canadian provinces.
Infants and small children should be
seated in an infant or child restraint
system, which is properly secured by
the lap belt portion of the lap-shoulder
belt, and that complies with U.S.
Federal Motor Safety Standard 213

and Canadian Motor Vehicle Safety
Standard 213.1.
A statement by the child restraint
manufacturer of compliance with this
standard can be found on the
instruction label on the restraint and in
the instruction manual provided with
the restraint.
When using any infant or child
restraint system, be sure to carefully
read and follow all manufacturer's
instructions for installation and use.

Warning!

Rear-facing child restraints must not
be used in a front seat They could be
struck by the airbag when it inflates
in a crash. If this happens, a child in
the restraint could be seriously
injured.

Infants and small children should
never be held on the lap while the
vehicle is in motion. During an
accident they would be almost
impossible to hold, and could be
crushed between the adult and the
dashboard.

Infants and small children should
never share a seat belt with another
occupant During an accident, they
could be crushed between the
occupant and seat belt.

Children too big for child restraint
systems should use regular seats
belts. Position the shoulder belt
across the chest and shoulder, not the
face or neck. A booster seat may be
necessary to achieve proper belt
positioning.

When the child restraint is not in use,
remove it from the car or secure it
with the seat belt to prevent the child
restraint from becoming a projectile
in the event of an accident.

U.S.A. Models only
Since 1986 all U.S. child restraints
comply with U.S. regulations without
the use of a tether strap.

Canada Models only
This vehicle can be equipped with
tether anchorages for a top tether strap.
Consult your authorized Mercedes­Benz dealer for installation of these
anchorages.

Index.

Have the system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

Note:
If the roll bar was raised automatically,
the process of raising or lowering the
soft top will take somewhat longer, as
the roll bar must first be lowered.

Whenever possible, park vehicle in the
shade as continuous exposure to sun
rays can prematurely deteriorate the
soft top material.

The soft top may become moldy if it is
kept in the storage compartment for an
extended period.

Therefore, we recommend raising and
airing it thoroughly with the side
windows open (do not expose it to the
sun) at regular intervals during the wet
and cold seasons.

Antenna

Cellular Telephone

Warning!

The antenna extends when switching
on the radio and/or telephone.

Note:
To retract the antenna (e.g. when
entering a car wash) both radio and
telephone must be switched off.

The vehicle is prepared for the
installation of a cellular telephone. For
further information and installation
contact your authorized Mercedes­Benz dealer.

Some jurisdictions prohibit the
driver from using a cellular
telephone while driving a vehicle.
Therefore, for safety reasons, the
driver should not use the cellular
telephone while the vehicle is in
motion. Stop the vehicle in a safe
location before answering or placing
a call.

Drinking and Driving

Driving Off

Warning!

Drinking and driving can be a very
dangerous combination. Even a small
amount of alcohol or drugs can affect
your reflexes, perceptions and
judgment. The possibility of a serious
or even fatal accident is sharply
increased when you drink and drive.
Please don't drink and drive or allow
a friend to drive when he has been
drinking.

Test the brakes briefly after driving
off. Perform this procedure only when
the road is clear of other traffic.
Warm up the engine smoothly. Do not
place full load on the engine until the
operating temperature has been
reached.

Warning!

Keep driver's foot area clear at all
times. Objects stored in this area
may impair pedal movement.

Parking Brake

To engage, depress parking brake
pedal. With the key in steering lock
position 2, the brake warning lamp in
the instrument cluster should come on
brightly (function check for lamp).
To release the parking brake, pull
handle on instrument panel. The brake
warning lamp in the instrument cluster
should go out (also see brake warning
lamp, page 88).

76

Automatic Transmission

The automatic transmission
selects individual gears auto­matically, dependent upon

• Selector lever position

• Accelerator position

• Vehicle speed

Important!

When parking the car and before
working on the vehicle with the engine
running, firmly depress the parking
brake pedal and shift the selector lever
into "P".

Driving

The selector lever is automatically
locked while in position "P". To move
the selector lever out of position "P",
the service brake pedal must be firmly
depressed before the shift lock will
release.

Shift selector lever to the desired
position only when the engine is idling
normally and the service brake is
applied. Do not release the brake until
ready to drive. The vehicle may
otherwise start creeping when the
selector lever is in drive or reverse
position.

Warning!

It is dangerous to shift the selector
lever out of "P" or "N" if the engine
speed is higher than idle speed. If
your foot is not on the brake pedal,
the car could accelerate quickly
forward or in reverse. You could lose
control of the car and hit someone or
something. Only shift into gear when
the engine is idling normally and
when your right foot is firmly on the
brake pedal.

Important!

After selecting any driving position
from "N" or "P", wait a moment to
allow the gear to fully engage before
accelerating, especially when the
engine is cold.

Accelerator position

Partial throttle = early upshifting =
normal acceleration

Full throttle = later upshifting = rapid
acceleration

Kickdown (depressing the accelerator
beyond full throttle) = downshifting to
next lowest gear = maximum
acceleration. Once the desired speed is
attained, ease up on the accelerator ­the transmission shifts up again.

77

Selector Lever Positions SL 320

The automatic gear shifting process can
be adapted to specific operating
conditions using the selector lever.

P Parking lock.

The parking lock is an additional
safeguard to the parking brake when
parking the vehicle. Engage only
with the car stopped.

Note:
The key can be removed from the
steering lock only with the selector
lever in position "P". With the key
removed, the selector lever is
locked in position "P".

R Reverse gear.

Shift to reverse gear only with the
car stopped.
N Neutral.
No power is transmitted from the
engine to the rear axle. When the
brakes are released, the vehicle
can be moved freely (pushed or
towed). Do not engage "N" while
driving except to coast when the
vehicle is in danger of skidding
(e.g. on icy roads, see page 19).

Important!

Coasting the vehicle for an ex­tended period of time with
selector lever in "N" can result in
transmission damage. That is not
covered by the MERCEDES­BENZ Limited Warranty.

D The transmission automatically

upshifts to 5th gear. Position "D"
provides optimum driving
characteristics under all normal
operating conditions.

4 Upshift to 4th gear only.

Suitable for performance driving.

3 Upshift to 3rd gear only. Suitable

for moderately steep hills. Since
the transmission does not shift
higher than 3rd gear, this gear
selection will allow use of the
engine's braking power downhill.

2 Upshift to 2nd gear only. For

driving in mountainous regions
or under extreme operating
conditions. This gear selection will
allow use of the engine's braking
power when descending steep
grades.

Important!

With selector lever in position "D", "4"
or "3", upshifting from 1st to 2nd to
3rd gear is delayed depending on
vehicle speed and engine temperature.
This allows the catalytic converter to
heat up more quickly to operating
temperatures.

During the brief warm-up period this
delayed upshift and increased engine
noise might be perceived as a
malfunction. However, neither the
engine nor transmission are negatively
affected by this mode of operation.

78

The delayed upshift is effective with
vehicle speeds below 31 mph (50
km/h) at partial throttle and engine
temperatures below 95°F (35°C).

To avoid over-revving the engine, the
selector lever cannot be moved to a
lower gear if the vehicle speed exceeds
the speed limit of that gear.

Warning!

On slippery road surfaces, never
downshift in order to obtain braking
action. This could result in rear
wheel slip and reduced vehicle
control. Your vehicle's ABS will not
prevent this type of loss of control.

To prevent the engine from laboring at
low RPMs, do not allow the engine
speed to drop too low on uphill
gradients.

Depending on the degree of the incline,
shift selector lever to a lower gear early
enough to maintain engine RPM within
the best torque range.

Maneuvering

To maneuver in tight areas, e.g. when
pulling into parking space, control the
car speed by gradually releasing the
brakes. Accelerate gently and never
abruptly step on the accelerator.

To rock a car out of soft ground (mud
or snow), alternately shift from forward
to reverse, while applying slight partial
throttle.
Rocking a car free in this manner may
cause the ABS warning lamp to come
on. Turn off and restart the engine to
clear the malfunction indication.

Stopping

For brief stops, e.g. at traffic lights,
leave the transmission in gear and hold
vehicle with the service brake.
For longer stops with the engine idling,
shift into "N" or "P".
When stopping the car on an uphill
incline, do not hold it with the
accelerator, use the brake. This avoids
unnecessary transmission heat build
up.

Warning!

Getting out of your car with the
selector lever not fully engaged in
position "P" is dangerous. When
parked on a steep incline, position
"P" alone may not prevent your
vehicle from rolling, possibly hitting
people or objects.
Always set the parking brake in
addition to shifting to position "P".

When parked on an incline, also turn
front wheel against curb.

79

Selector Lever Positions 500 SL,
600 SL

The automatic gear shifting process
can be adapted to specific operating
conditions using the selector lever.

P Parking lock.

The parking lock is an additional
safeguard to the parking brake
when parking the vehicle. Engage
only with the car stopped.

Note:
The key can be removed from the
steering lock only with the selector
lever in position "P". With the key
removed, the selector lever is
locked in position "P".

R Reverse gear.

Shift to reverse gear only with the
car stopped.

N Neutral.

No power is transmitted from the
engine to the rear axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
Do not engage "N" while driving
except to coast when the vehicle is
in danger of skidding (e.g. on icy
roads, see Winter driving
Instructions in Index).

Important!

Coasting the vehicle for an ex­tended period of time with selector
lever in "N" can result in
transmission damage. That is not
covered by the MERCEDES­BENZ Limited Warranty.

D The transmission automatically

upshifts to 4th gear. Position "D"
provides optimum driving
characteristics under all normal
operating conditions.

4 Upshift to 4th gear only. Suitable

for performance driving. To shift
from position "D" to "4", push
selector lever to the left.

3 Upshift to 3rd gear only. Suitable

for moderately steep hills. Since
the transmission does not shift
higher than 3rd gear, this gear
selection will allow use of the
engine's braking power downhill.

2 Upshift to 2nd gear only. For

driving in mountainous regions or
under extreme operating
conditions. This gear selection
will allow use of the engine's
braking power when descending
steep grades.

1 In this position, the engine's

braking effect is utilized by
shifting into 1st gear. Use this
position while descending very
steep or lengthy downgrades and
only at speeds below 40 mph (60
km/h).

Important!

With selector lever in position "D", "4"
or "3", upshifting from 1st to 2nd to
3rd gear is delayed depending on
vehicle speed and engine temperature.

80

This allows the catalytic converter to
heat up more quickly to operating
temperatures.
During the brief warm-up period this
delayed upshift and increased engine
noise might be perceived as a
malfunction. However, neither the
engine nor transmission are negatively
affected by this mode of operation.

The delayed upshift is effective
with vehicle speeds below

31 mph (50 km/h) at partial throttle
and engine temperatures below
95°F(35°C).

Warning!
On slippery road surfaces, never
downshift in order to obtain braking
action. This could result in rear
wheel slip and reduced vehicle
control. Your vehicle's ABS will not
prevent this type of loss of control.

Maneuvering

To maneuver in tight areas, e.g. when
pulling into parking space, control the
car speed by gradually releasing the
brakes. Accelerate gently and never
abruptly step on the accelerator.

Stopping

For brief stops, e.g. at traffic lights,
leave the transmission in gear and hold
vehicle with the service brake.

For longer stops with the engine idling,
shift into "N" or "P".

When stopping the car on an uphill
incline, do not hold it with the
accelerator, use the brake. This avoids
unnecessary transmission heat build up.

Warning!

To avoid overrevving the engine when
the selector lever is moved to a lower
driving range, the transmission will not
shift to a lower gear as long as the
vehicle speed exceeds the speed limit
of that gear.

To prevent the engine from laboring at
low RPMs, do not allow the engine
speed to drop too low on uphill
gradients.

Depending on the degree of the incline,
shift selector lever to a lower gear
range early enough to maintain engine
RPM within the best torque range.

Getting out of your car with the
selector lever not fully engaged in
position "P" is dangerous. When
parked on a steep incline, position
"P" alone may not prevent your
vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in
addition to shifting to position "P".
When parked on an incline, also turn
front wheel against curb.

81

S Standard mode

Press switch on symbol "S". Use
this mode for all regular driving.

The vehicle starts out in 1st gear.

W Winter (snow and ice) mode

Press switch on symbol "W". The
vehicle starts out in 2nd gear, except
with selector lever in 1st gear, or
with accelerator pedal in kick-down
position.

Emergency Operation
(Limp Home Mode)

If vehicle acceleration worsens, or the
transmission no longer shifts, the
transmission operates in Limp Home
Mode. In addition the "CHECK
ENGINE" malfunction indicator lamp
in the instrument cluster may come on.

In this mode only the 2nd gear or
reverse gear can be activated.

Program Mode Selector Switch

The transmission is provided with a
selector switch for Standard "S" and
Winter (snow and ice) "W" program
modes.

Warning!

Always be certain of the program
mode selected since the vehicle
driving characteristics change with
the selection of the program mode.

The "W" mode helps to improve
traction and driving stability of the
vehicle.
With hard acceleration the upshifts
occur at lower vehicle and engine
speeds than in the "S" program
mode.

Warning!

During stops use the brake, especially
on an incline, to prevent the vehicle
from rolling.

To engage 2nd gear or reverse:

1. Stop the vehicle.

2. Move selector lever to position "P".

3. Turn off the engine.

4. Wait 10 seconds.

5. Restart the engine.

6. Move selector lever to
position "D" (for 2nd gear), or
move selector lever to position "R"
(for reverse gear).

Have the transmission checked at your
authorized Mercedes-Benz dealer as
soon as possible.

82

Cruise Control

speed.

Any given speed above approximately
25 mph (40 km/h) can be maintained
with the cruise control by operating the
lever.

1. Accelerate and set:
Lift lever briefly to set speed.
Hold lever up to accelerate.

2. Decelerate and set:
Depress lever briefly to set
Hold lever down to decelerate.

Normally the vehicle is accelerated to
the desired speed with the accelerator.

Speed is set by briefly pushing the
lever to position 1 or 2. The accelerator
can be released.

The speed can be increased (e.g. for
passing) by using the accelerator. As
"soon as the accelerator is released, the
previously set speed will be resumed
automatically.

If a set speed is to be increased or
decreased slightly, e.g. to adapt to the
traffic flow, hold lever in position 1 or
2 until the desired speed is reached, or
briefly tip the control lever in the
appropriate direction for increases or
decreases in 1 km/h (0.6 mph)
increments. When the lever is released,
the newly set speed remains.

3. Canceling
To cancel the cruise control,
briefly push lever to position 3.

When you step on the brake or
clutch pedal or the vehicle speed
drops below approx. 35 km/h (22
mph), for example when driving
upgrade, the cruise control will be
canceled.
If the cruise control cancels by
itself and remains inoperative until
the engine is restarted, have the
system checked at your authorized
MERCEDES-BENZ dealer as soon
as possible.

4. Resume
If the lever is briefly pushed to
position 4 when driving at a speed
exceeding approx. 40 km/h (25
mph), the vehicle resumes the
speed which was set prior to the
cancellation of the cruise control.
The last memorized speed is
canceled when the key in the
steering lock is turned to position 1
or 0.

83

Note:
If the engine does not brake the vehicle
sufficiently while driving on a
downgrade, the speed you set on the
cruise control may be exceeded and
you may have to step on the brake
pedal to slow down. As soon as the
grade eases, the cruise controlled speed
will again be maintained as long as the
brakes were not previously applied, or
the lever may be used to resume the
previously set speed if the brakes were
applied.

Warning!

Only use the cruise control if the
traffic and weather conditions make
it advisable to travel at a steady
speed.

• The use of cruise control
can be dangerous on winding
roads or in heavy traffic
because conditions do not
allow safe driving at a
steady speed.

• The use of cruise control
can be dangerous on slippery
roads. Rapid changes
in tire adhesion can result
in wheel spin and loss of
control.

The "Resume" function should only
be operated if the driver is fully
aware of the previously set speed and
wishes to resume this particular
preset speed.

Caution!

When driving with the cruise control
engaged, the transmission slector lever
must not be shifted to position "N" as
otherwise the engine will overrev,
possibly causing engine damage that is
not covered by the Mercedes-Benz
Limited Warranty.

84

Charge Indicator Lamp

Should the charge indicator lamp fail to
come on prior to starting when the key
is in steering lock position 2 or should
it fail to go out after starting or during
operation, this indicates a fault which
must be repaired at an authorized
MERCEDES-BENZ dealer
immediately.

If the charge indicator lamp comes on
while the engine is running, this may
indicate that the poly-V-belt has
broken. Should this condition occur,
the poly-V-belt must be replaced before
continuing to operate the vehicle.
Otherwise, the engine will overheat due
to an inoperative water pump which
may result in damage to the engine.

Do not continue to drive the vehicle
with the charge indicator lamp
illuminated. Doing so could result in
engine damage that is not covered by
the Mercedes-Benz Limited Warranty.

Engine Oil Pressure Gauge

The oil pressure at idle speed may drop
if the engine is at operating
temperature. This will not jeopardize
the engine's operational reliability.

Pressure must, however, rise
immediately upon acceleration.

Note:
If the oil pressure gauge needle drops
to "0" with the engine running, then
damage to the engine may occur with
continued operation. Turn off engine
immediately and contact an authorized
Mercedes-Benz dealer. Do not operate
the car until the condition is repaired.

Low Engine Oil Level Warning
Lamp

With the key in steering lock position
2, the oil pressure warning lamp comes
on and goes out with the engine
running.

If the warning lamp comes on with the
engine running and at operating
temperature, the engine oil level has

dropped to approximately the
minimum mark on the dipstick.
When this occurs, the warning lamp
will first come on intermittently and
then stay on if the oil level drops
further.

If no oil leaks are noted and there is
indicated engine oil pressure, continue
to drive to the nearest service station
where the engine oil should be topped
to the "full" mark on the dipstick with
an approved oil.

The low engine oil level warning light
should not be ignored. Extended
driving with the light illuminated could
result in engine damage that is not
covered by the Mercedes-Benz
Limited Warranty.

In addition to the warning lamp, the
engine oil level should be periodically
checked with the dipstick, for example
during a fuel stop, or before a long trip.
See Index.

85

Engine Oil Consumption

Fuel Consumption Gauge

Tachometer

Engine oil consumption checks should
only be made after the break-in period.
During the break-in period, higher oil
consumption may be noticed and is
normal. Frequent driving at high
engine speeds results in increased
consumption.

While driving, instantaneous fuel
consumption is indicated in miles per
gallon (mpg), or in Canada liters per
100 kilometers (I/100 km).

With the engine switched off, the
needle reads "0".

Due to system design, maximum
consumption is indicated at idle speed.

Red marking on tachometer:
Excessive engine speed.
Avoid this engine speed, as it may
result in engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
For engine protection, the fuel supply
is interrupted if the engine is operated
within the red marking.

86

Fuel Reserve Warning Lamp

Warning!

Warning!

With the key in steering lock position
2, the fuel reserve warning lamp comes
on and goes out with the engine
running.
If the warning lamp does not go out
after starting the engine or if it comes
on while driving, it indicates that the
fuel level is down to the reserve
quantity of approx. 2.6 gal (10 liters).

Outside Temperature Indicator

The temperature sensor is located in the
front bumper area. Due to its location,
the sensor can be affected by road or
engine heat during idling or slow
driving. This means that the accuracy
of the displayed temperature can only
be verified by comparison to a
thermometer placed next to the sensor,
not by comparison to external displays
(e.g. bank signs, etc.).
Adaptation to ambient temperature
takes place in steps and depends on the
prevailing driving conditions (stop-and­go or moderate, constant driving) and
amount of temperature change.

The outside temperature indicator is
not designed to serve as an Ice­Warning Device and is therefore un­suitable for that purpose. Indicated
temperatures just above the freezing
point do not guarantee that the road
surface is free of ice.

Coolant Temperature Gauge

If the antifreeze mixture is effective to

-22°F (-30°C ), the boiling point of the

coolant in the pressurized cooling
system of your vehicle is approx.
266°F (130°C).
During severe operating conditions and
stop-and-go city traffic, the coolant
temperature may rise close to the red
marking.
The engine should not be operated with
the coolant temperature in the red
zone. Doing so may cause serious
engine damage which is not covered by
the Mercedes-Benz Limited Warranty.

• Driving when your engine is
badly overheated can cause some
fluids which may have leaked into
the engine compartment to catch
fire. You could be seriously
burned. Turn off the engine and
get out of the car until it cools
down.

• Steam from an overheated engine
can cause serious burns and can
occur just by opening the engine
hood. Stay away from the engine
if you see or hear steam coming
from it. Turn off the engine and
do not stand near the car until it
cools down.

87

Low Engine Coolant Level
Warning Lamp

With the key in steering lock position
2, the warning lamp comes on and goes
out with the engine running.

If the warning lamp does not go out
after starting the engine, or if it comes
on while driving, then the coolant level
has dropped below the required level.
If no leaks are noticeable and the
engine temperature does not increase,
continue to drive to the nearest service
station and have coolant added to the
coolant system. (see Index).

The low engine coolant level warning
light should not be ignored. Extended
driving with the light illuminated may
cause serious engine damage not
covered by the Mercedes-Benz Limited
Warranty.

In cases of major or frequent minor
coolant loss, have the cooling system
checked at your authorized
MERCEDES-BENZ dealer as soon as
possible.

Note:
Do not drive without coolant in the
cooling system. The engine can
overheat causing major engine damage.

Monitor the coolant temperature gauge
while driving.

Warning!

Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene
glycol which may burn if it comes
into contact with hot engine parts.
You can be seriously burned.

Low Windshield and Headlamp
Washer Fluid Level Warning Lamp

With the key in steering lock position
2, the warning lamp comes on and
goes out with the engine running.

If the warning lamp comes on with the
engine running, the level of the
reservoir has dropped to approx. 1/4 of
the total volume. The reservoir should
be refilled with MB Windshield
Washer Concentrate "S" and water (or
commercially available premixed
windshield washer solvent/antifreeze,
depending on ambient temperature ­see Index) at the next opportunity. The
reservoir for the windshield and
headlamp washer system is located in
the engine compartment.

88

Roll Bar Warning Lamp

With the key in steering lock position
2, the warning lamp comes on and goes
out with the engine running.

Warning!

If the warning lamp does not go out
after starting the engine, or if it
comes on while driving, and the
indicator lamps in the roll bar switch
blink simultaneously, then the roll
bar system is defective and may not
activate in an accident. In this case,
raise the roll bar manually (see
Index) before continuing to drive.

Have the roll bar system checked at
your authorized MERCEDES-BENZ
dealer as soon as possible.

Seat Belt and Backrest Lock
Warning Lamp

With the key in steering lock position
2, the warning lamp comes on and an
audible warning sounds for a short
time if the driver's seat belt is not
fastened.

If a backrest is not engaged in its lock,
an audible warning will sound
intermittently for up to approx. 20
seconds.

After starting the engine, the warning
lamp blinks for a brief period to
remind the driver and passenger to
fasten seat belts before driving off.

If the warning lamp does not go put
after blinking briefly, but is instead lit
continuously, then a backrest is not
engaged in its lock.

The warning lamp goes out as soon as
the backrest is engaged in its lock.

Exterior Lamp Failure Indicator
Lamp

With the key in steering lock position
2, a dim indicator lamp comes on and
goes out with the engine running.

With the key in steering lock position 2
or with the engine running, a bright
illumination of this lamp indicates an
exterior lamp failure (except high
mounted stop lamp).

Note:
The indicator lamp will also come on if
an incorrect bulb is installed.
If additional lighting equipment is
installed (e.g. auxiliary headlamps
etc.) be certain to connect into the
fuse before the failure indicator
monitoring unit in order to avoid
damaging the system.

If an exterior lamp fails, the in­dicator lamp will come on only
when that lamp is switched on.

If the backrest is locked and the
warning lamp does not go out, have
the system checked at your authorized
MERCEDES-BENZ dealer as soon as
possible.

If a brake or turn signal lamp fails, the
lamp failure indicator will come on
when applying the brake or actuating
the turn signal and stay on until the
engine is turned off.

89

Brake Pad Wear Indicator Lamp

Brake Warning Lamp

Warning!

The brake pad wear indicator lamp in
the instrument cluster comes on when
the key in the steering lock is turned to
position 2 and goes out when the
engine is running.

If the indicator lamp lights up during
braking, this indicates that the front
wheel brake pads are worn down
(vehicles equipped with ASR front
and/or rear wheel brake pads).

Have the brake system checked at your
authorized MERCEDES-BENZ dealer
as soon as possible.

The brake warning lamp will come on:

• when there is insufficient brake
fluid in the reservoir (engine
running and parking brake
released)

• when the parking brake is set
(engine running)

When the minimum mark on the
reservoir is reached, have the brake
system checked for brake pad thickness
and leaks.

To test the brake warning lamp, turn
the key in steering lock to position 2.
The brake warning lamp comes on, and
should go out when the engine is
running.

Driving with the brake warning
lamp on can result in an accident.
Have your brake system checked
immediately if the brake warning
lamp stays on. Don't add brake fluid
before checking the brake system.
Overfilling the brake fluid reservoir
can result in spilling brake fluid on
hot engine parts and the brake fluid
catching fire. You can be seriously
burned.

90

Antilock Brake System (ABS)

Important!

The ABS improves steering control of
the vehicle during braking maneuvers.
For maximum benefit, do not pump the
brake pedal, rather use firm, steady
brake pedal pressure.

The ABS prevents the wheels from
locking up above a vehicle speed of
approximately 5 mph (8 km/h)
independent of road surface conditions.

At the instant one of the wheels is
about to lock up, a slight pulsation can
be felt in the brake pedal, indicating
that the ABS is in the regulating mode.

On slippery road surfaces, the ABS
will respond even with only slight
brake pedal pressure. The pulsating
brake pedal can be an indication of
hazardous road conditions and
functions as a reminder to take extra
care while driving.

The ABS warning lamp in the
instrument cluster comes on with the
key in steering lock position 2 and
should go out with the engine running.

If the charging voltage falls below 10
volts, the warning lamp comes on and
the ABS is switched off. When the
voltage is above this value again, the
warning lamp should go out and the
ABS will be operational.

If the ABS warning lamp does not go
out or comes on while driving, it
indicates that the ABS has detected a
malfunction and has switched off. In
this case, the brake system functions in
the usual manner, but without antilock
assistance.

Have the system checked at your
authorized MERCEDES-BENZ dealer
as soon as possible.

Warning!

Even the ABS cannot prevent the
natural laws of physics from acting
on the vehicle. The ABS cannot
prevent accidents, including those
resulting from excessive speed in
turns, following another vehicle too
closely, or aquaplaning. Only a safe,
attentive, and skillful driver can
prevent accidents. The capabilities of
an ABS equipped car must never be
exploited in a reckless or dangerous
manner which could jeopardize the
user's safety or the safety of others.

Notes:

To alert following vehicles to slippery
road conditions you discover, operate
your hazard warning flashers as
appropriate.

With the ABS malfunctioning, the
ETS, ASR or ESP are also switched
off. Both malfunction indicator lamps
come on with the key in steering lock
position 2.

91

Electronic Traction System
(ETS)

The ETS improves vehicle traction,
especially under slippery road
conditions. It engages at vehicle speeds
up to approximately 24 mph (40 km/h),
and applies the brakes to the spinning
drive wheel. At approximately 50 mph
(80 km/h), the ETS switches off.

With the key in steering lock position
2, the yellow ETS malfunction
indicator lamp in the instrument cluster
and the ETS warning lamp in the
speedometer dial come on. They must
go out when the engine is running.

If the ETS malfunction indicator lamp
comes on with the engine running, a
malfunction has been detected.

Caution!

If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), or when testing the parking
brake on a brake test dynamometer, the
engine must be shut off. Otherwise, the
electronic traction system will
immediately be engaged and will apply
the rear wheel brakes.

The ETS warning lamp, located in the
speedometer dial, starts to flash at any
vehicle speed, as soon as the tires lose
traction and the wheels begin to spin.

Important!

If the ETS warning lamp flashes:

• during take-off, apply as little
throttle as possible,

• while driving, ease up on the
accelerator.

Adapt your speed and driving to the
prevailing road conditions.

Have the ETS checked at your
authorized Mercedes-Benz dealer as
soon as possible.

With the ABS malfunctioning, the ETS
is also switched off.

Notes:
If the ETS malfunction indicator lamp
comes on while the ETS warning lamp
flashes, the electronic traction system
is being switched off temporarily to
prevent overheating of the drive wheel
brakes.

In winter operation, the maximum
effectiveness of the electronic traction
system is only achieved with
Mercedes-Benz recommended M + S
radial-ply tires and/or snow chains.

92

Acceleration Slip Regulation (ASR)

The acceleration slip regulation will
engage at all vehicle speeds, if one or
both drive wheels begin to lose traction
and spin due to excessive acceleration.
While engaged, the yellow warning
lamp in the speedometer flashes.

With the acceleration slip regulation
engaged, the brake is applied to the
spinning drive wheel until it regains
sufficient traction. If both drive wheels
lose traction and spin, the brake is
applied to both drive wheels and
simultaneously, engine torque is
limited, to improve the vehicle's
driving stability.

As traction on the road surface
increases, the allowable engine torque
also increases again and the brake is no
longer applied to drive wheels.

Important!

If the ASR warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.

Caution!

If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), the engine must be shut off.
Otherwise, the acceleration slip
regulation will immediately be engaged
and will apply the rear wheel brakes.

Notes:
With the key in steering lock position
2, the yellow malfunction indicator
lamp in the instrument cluster and the
yellow ASR warning lamp in the
speedometer dial come on. They must
go out when the engine is running.

If the ASR malfunction indicator lamp
comes on with the engine running, a
malfunction has been detected.
Pressing the accelerator pedal will
require greater effort. Only partial
engine output is available.

Have the ASR checked at your
authorized Mercedes-Benz dealer as
soon as possible.

With the ABS malfunctioning, the
ASR is also switched off.
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
acceleration slip regulation may
activate (yellow ASR malfunction
indicator lamp in instrument cluster
comes on). For this reason, all wheels,
including the spare wheel, must have
the same tire size.

When testing the parking brake on a
brake test dynamometer, the engine
must be shut off. Otherwise, the
acceleration slip regulation will
immediately be engaged and will apply
the rear wheel brakes.

In winter operation, the maximum
effectiveness of the acceleration slip
regulation is only achieved with
Mercedes-Benz recommended M + S
radial-ply tires and/or snow chains.

93

ASR Control Switch

To improve the vehicle's traction when
driving with snow chains, or starting
off in deep snow, sand or gravel, press
the upper half of the ASR switch. The
ASR warning lamp, located in the
speedometer dial, is continuously
illuminated.

The ASR warning lamp, located in the
speedometer dial, starts to flash at any
vehicle speed as soon as the tires lose
traction and the wheels begin to spin.
To switch off: press lower half of the
switch (the ASR warning lamp in the
speedometer dial goes out).

Important!

ASR control switch located in center
console

With the ASR system switched off, the
engine torque reduction feature is
cancelled. Therefore, the enhanced
vehicle stability offered by ASR is
unavailable.

Adapt your speed and driving to the
prevailing road conditions.
A portion of the ASR system remains
active, even with the switch in the OFF
position.

If one drive wheel loses traction and
begins to spin, the brake is applied
until the wheel regains sufficient
traction. The traction control engages
at vehicle speeds up to approximately
24 mph (40 km/h), and switches off at
50 mph (80 km/h).

If the ASR warning lamp flashes:

• during take-off, apply as little
throttle as possible,

• while driving, ease up on the
accelerator.

94

Electronic Stability Program
(ESP)

The ESP enhances directional control
and improves traction of the vehicle
under any driving condition.

Over/understeering of the vehicle is
counteracted by applying brakes to the
left or right side wheels. The ESP
warning lamp, located in the
speedometer dial, starts to flash.

Important!

If the ESP warning lamp flashes, adapt
your speed and driving to the
prevailing road conditions.

Caution!

If the vehicle is towed with the front
axle raised (see Towing the vehicle in
Index), the key must not be in steering
lock position 2. Otherwise, the
electronic stability program will
immediately be engaged and will apply
the rear wheel brakes.

Notes:

With the key in steering lock position
2, the yellow ESP and EPC
malfunction indicator lamps in the
instrument cluster and the yellow
warning lamp in the speedometer dial
come on. They must go out when the
engine is running.

If the ESP or EPC malfunction
indicator lamp comes on with the
engine running, a malfunction has been
detected. It is possible that now only
partial engine output is available.

Have the ESP checked at your
authorized Mercedes-Benz dealer as
soon as possible.

With the ABS malfunctioning, the ESP
is also switched off.

Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
electronic stability program may
activate (yellow ESP malfunction
indicator lamp in instrument cluster
comes on). For this reason, all wheels,
including the spare wheel, must have
the same tire size.

When testing the parking brake on a
brake test dynamometer, the engine
must be shut off. Otherwise, the
electronic stability program will
immediately be engaged and will apply
the rear wheel brakes.

In winter operation, the maximum
effectiveness of the electronic stability
program is only achieved with
Mercedes-Benz recommended M + S
radial-ply tires and/or snow chains.

Adaptive Damping System
(ADS)

Adaptive Damping System
Adjustment

Depending upon road surface
conditions, load, driving style, ADS
will automatically adjust the optimal
ride firmness.

The indicator lamp comes on with the
key in steering lock position 2 and goes
out when the engine is running.

If the indicator lamp stays on after the
engine is running or comes on while
driving, then the system has detected a
malfunction.

We recommend that you visit an
authorized Mercedes-Benz dealer as
soon as possible to have the system
checked-out.

Note:
If the battery was disconnected, the
indicator lamp will only go out after the
engine is started and the steering wheel
is turned from full left to full right lock
and returned to the center position.

The switch is located in the center
console.

Emission Control

Warning!

On-Board Diagnostic System

Certain systems of the engine serve to
keep the toxic components of the
exhaust gases within permissible limits
required by law.

These systems, of course, will function
properly only when maintained strictly
according to factory specifications.
Any adjustments on the engine should,
therefore, be carried out only by
qualified MERCEDES-BENZ
technicians. Engine adjustments should
not be altered in any way. Moreover,
the specified service and maintenance
jobs must be carried out regularly
according to MERCEDES-BENZ
servicing requirements. For details
refer to the Maintenance Booklet.

Inhalation of exhaust gas is
hazardous to your health. All
exhaust gas contains carbon
monoxide, and inhaling it can cause
unconsciousness and lead to death.
Do not run the engine in confined
areas (such as a garage) which are
not properly ventilated. If you think
that exhaust gas fumes are entering
the vehicle while driving, have the
cause determined and corrected im­mediately. If you must drive under
these conditions, drive only with at
least one window fully open.

The Sequential Multiport Fuel
Injection (SFI) control module
monitors emission control components
that either provide input signals to or
receive output signals from the control
module. Malfunctions resulting from
interruptions or failure of any of these
components are indicated by the
"CHECK ENGINE" malfunction
indicator lamp in the instrument cluster
and are simultaneously stored in the
SFI control module.

If the "CHECK ENGINE" malfunction
indicator lamp comes on, have the
system checked at your authorized
Mercedes-Benz dealer as soon as
possible.

An on-board diagnostic connector
allows the accurate identification of
system malfunctions through the
readout of diagnostic trouble codes.

Connector location:

SL 320 - passenger compartment, near
the accelerator pedal. SL 500, SL 600 ­engine compartment, on firewall.
