Mercedes-Benz E-class 1999 Additions to Manual

Warning!

Children 12 years old and under
must never ride in the front seat,
except in a Mercedes-Benz
authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the
vehicle to deactivate the passenger
side front airbag when it is properly
installed. Otherwise they will be
struck by the airbag when it inflates
in a crash. If this happens, serious or
fatal injury will result.

According to accident statistics,
children are safer when properly
restrained in the rear seating
positions than in the front seating
positions. Infants and small children
must ride in back seats and be seated
in an infant or child restraint system,
which is properly secured with the
vehicle's seat belt, fully in
accordance with the child seat
manufacturer's instructions.

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 must ride in back seats using
regular seat belts. Position shoulder
belt across chest and shoulder, not
face or neck. A booster seat is
necessary to achieve proper belt
positioning for children from 41 lbs.
to the point where a lap/shoulder
belt fits properly without one.

When the child restraint is not in
use, remove it from the vehicle 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 is provided with tether
anchorages for a top tether strap.
Consult your authorized Mercedes­Benz dealer for installation of these
anchorages.

In compliance with Canadian Motor
Vehicle Safety Standard 210.1, child
restraint tether anchorage hardware is
attached to the tool kit located in the
trunk

With the engine at idle speed, the
charging rate of the alternator (output)
is limited.

It is therefore recommended to turn off
unnecessary electrical consumers while
driving in stop-and-go traffic. This
precaution helps to avoid draining of
the battery.

Unnecessary strain on the battery and
charging system may be minimized by
turning off the following power
consumers, for example: Heated seats,
rear window defroster. In addition, the
automatic climate air volume control
should be set to the lowest position.

The steering lock can only be unlocked
with the vehicle battery properly
charged and connected.

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
judgement.

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
anyone to drive after drinking.

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.

When starting off on a slippery surface,
do not allow one drive wheel to spin for
an extended period.

Warning!

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

82

Automatic Transmission

Driving

Important!

The automatic transmission selects
individual gears automatically,
dependent upon

• Selector lever position

• Program mode selector

• Accelerator position

• Vehicle speed

The gear shifting process is
continuously adapted, dependent on the
driving style, the driving situation and
the road characteristics.

Important!

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

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 enqine
speed is higher than idle speed. If
your foot is not firmly on the brake
pedal, the vehicle could accelerate
quickly forward or in reverse. You
could lose control of the vehicle 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.

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
a lower gear = maximum acceleration.
Once the desired speed is attained, ease
up on the accelerator - the transmission
shifts up again.

83

P Parking position.

The parking position is to be used
when parking the vehicle. Engage
only with the car stopped. The
parking position is not intended to
serve as a brake when the vehicle is
parked. Rather, the driver should
always use the parking brake in
addition to placing the selector lever
in park to secure the vehicle.

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).

Selector Lever Positions

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

Note:

The electronic key can be removed
from the steering lock only with the
foot off the brake pedal and the
selector lever in position "P". With
the electronic key removed, the
selector lever is locked in position
"P".

R Reverse gear.

Shift to reverse gear only with the
vehicle stopped.
Dependent on the program mode
selector switch position "S" or "W"
the maximum speed in the reverse
gear is different. However, it is not
possible to change the program
mode while in reverse.

Important!

Coasting the vehicle, or driving for
any other reason with selector lever
in "N" can result in transmission
damage that is not covered by the
Mercedes-Benz Limited Warranty.

84

D The transmission automatically

owngrades and only at speeds below

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

4 Upshift through 4th gear only.

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

3 Upshift through 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 through 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
d
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. 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).

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, if the engine's
speed limit would be exceeded. In this
case there will be no downshift, even
when the vehicle speed reaches the
engine's speed limit of that gear, e.g. by
applying the service brakes. Continue
driving in the

usual manner. The transmission will
then shift down automatically.

To prevent the engine from laboring at
low RPM when driving uphill
gradients or with your vehicle heavily
loaded, the automatic transmission will
downshift when necessary to maintain
engine RPM within the best torque
range.

Warning!

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

85

Maneuvering

Warning!

To maneuver in tight areas, e.g. when
pulling into a parking space, control the
vehicle speed by gradually releasing
the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground
(mud or snow), alternately shift from
forward to reverse, while applying slight
partial throttle.

Rocking a vehicle free in this manner
may cause the ABS malfunction
indicator 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" and hold the vehicle
with the service brake.

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

Getting out of your vehicle with the
selector lever not fully engaged in
position "P" is dangerous. Also,
when parked on an 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.

Program Mode Selector Switch

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

Caution!

Never change the program mode when
the selector lever is out of position "P".
It could result in a change of driving
characteristics for which you may not
be prepared.

Important!

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

86

S Standard mode

Press switch on symbol "S". Use
this mode for all regular driving.
The vehicle starts out in 1st gear.

Accelerator Operation: Fast on =
depressing the accelerator pedal
quickly (not into kickdown position)
while driving continuously, rather
than depressing the accelerator
pedal in the usual manner, will
cause the automatic transmission to
shift down into a lower gear. This
gear shifting process is dependent
on the current vehicle speed.

Fast off = there will be no upshift
when releasing the accelerator pedal
quickly, e.g. using the engine's
braking power during performance
driving.

W Winter/Wet (snow and ice) mode

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

The "W" mode helps to improve
traction and driving stability of the
vehicle.

The gear shifting process occurs at
lower vehicle and engine speeds
than in the "S" program mode.

Important!

Dependent on the program mode
selector switch position "S" or "W" and
the gear selector lever in position "R",
the ratio of power transmission changes.

Emergency Operation
(Limp Home Mode)

If vehicle acceleration worsens, or the
transmission no longer shifts, the
transmission is most likely operating
in Limp Home Mode which engages
when there is a malfunction at the
transmission. This condition may be
accompanied by the "CHECK
ENGINE" malfunction indicator lamp
in the instrument cluster coming on.
In this mode only the 2nd gear or
reverse gear can be activated.

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.

Cruise Control

maintained with the

Any given speed above approximately 25
mph (40 km/h) can be
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
speed.
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. After
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 lever in the appropriate
direction for increases or decreases in

0.6 mph (1 km/h) 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 pedal
or the vehicle speed drops below
approx. 25 mph (40 km/h), 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. 25 mph (40
km/h), the vehicle resumes the
speed which was set prior to the
cancellation of the cruise control.
The last memorized speed is
canceled when the electronic key in
the steering lock is turned to
position 1 or 0.

88

Notes:

Important!

Warning!

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.

Moving gear selector lever to position
"N" switches the cruise control off.

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.

Low Engine Oil Level Warning

When the symbol and message appear
while the engine is running and at
operating temperature, the engine oil
level has dropped to approximately the
minimum mark on the dipstick.

When this occurs, the warning will first
come on intermittently and then stay on
if the oil level drops further.
If no oil leaks are noted, 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

Warning!

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.

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.

92

Warning!

• 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.

• 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, get out of the
car and do not stand near the car
until it cools down.

Low Engine Coolant Level
Warning

When the symbol and message appear
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
should not be ignored. Extended
driving with the symbol displayed 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 Mercedes­Benz dealer as soon as possible.

Note:

Do not drive without coolant in the
cooling system. The engine will
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

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

Brake Warning

When the brake warning lamp and
message appear while the engine is
running, this means:

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

• the parking brake is set (engine
running).

Driving with the brake warning
lamp illuminated 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.

Note:

If you find that the minimum mark on
the brake fluid reservoir is reached,
have the brake system checked for
brake pad thickness and leaks.

94

Flexible Service System (FSS)

The FSS permits a flexible service
schedule that is directly related to the
operating conditions of the vehicle.

The symbol appears together with
a message in the multifunction indicator
prior to the next suggested service.
Depending on operating conditions
throughout the year, the next service is
calculated and displayed in days or
distance remaining.

The message is displayed for approx.
10 seconds when turning the electronic
key in steering lock to position 2, or it
can be canceled manually by pressing
button 0.

Once the suggested term has passed,
the symbol plus message
"EXCEEDED BY" appear, when turning
the electronic key to position 2.

The FSS display can also be called up
for approx.10 seconds with display
illuminated by pressing button 0 twice.

Following a completed service the
Mercedes-Benz dealer sets the counter
to 10 000 miles (Canada: 15 000 km)
and 365 days.

The counter can also be set by any
individual. To do so:

1. Turn electronic key in steering
lock to position 2.

2. Within 4 seconds press button 0
twice.

3. The present status for days or
distance is displayed. Within
10 seconds turn electronic key in
steering lock to position 0.

4. Press and hold button 0, while
turning electronic key in steering
lock to position 2 again. The pre
sent status for days or distance
is displayed once more. Continue
to hold button 0.
After approx. 10 seconds a signal
sounds, and the display shows
10 000 miles (Canada: 15 000 km).

5. Release button 0.

If the FSS counter was inadvertently
reset, have a Mercedes-Benz dealer
correct it.

95

Notes:

When disconnecting vehicle battery for
one or more days at a time, such days
will not be counted. Any such days not
counted by the FSS can be added by
your Mercedes-Benz dealer. The
interval between services is determined
by the kind of vehicle operation.
Driving at extreme speeds, and cold
starts combined with short distance
driving in which the engine does not
reach normal operating temperature,
reduce the interval between services.

Models E 320 and E 430, E 55 AMG:

The FSS allows for distances between
10 000 miles (Canada: 15 000 km) and
20 000 miles (Canada: 30 000 km), or
from 365 to 730 days between services.

Model E 300 TURBODIESEL:

The FSS allows for distances between
10 000 miles (Canada: 15 000 km) and
15 000 miles (Canada: 22 500 km), or
from 365 to 730 days between services.

However you choose to set your
reference numbers, the scheduled
services as posted in the Service
Booklet must be followed to properly
care for your vehicle.

96

Antilock Brake System (ABS)

tion 2

indicator lamps come on with the engine

ABS Control

Warning!

Important!

The ABS improves steering control of
the vehicle during braking maneuvers.
Do not pump the brake pedal, rather
use firm, steady brake pedal pressure.
Pumping the brake pedal defeats the
purpose for ABS and significantly
reduces braking effectiveness.

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.
Keep firm and steady pressure on the
brake pedal while experiencing the
pulsation.

On slippery road surfaces, the ABS will
respond even with light brake pedal
pressure because of the increased
likelihood of locking wheels. 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 malfunction indicator lamp in
the instrument cluster comes on with the
electronic key in steering lock posi
and should go out with the engine
running.

When the ABS malfunction indicator
lamp symbol and warning in the
instrument cluster come on while the
engine is running, 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.

With the ABS malfunctioning, the BAS,
ASR or ESP, if vehicle so equipped, are
also switched off. Both malfunction

running.

If the charging voltage falls below 10
volts, the malfunction indicator lamp
comes on and the ABS is switched off.
When the voltage is above this value
again, the malfunction indicator lamp
should go out and the ABS should be
operational.
Have the system checked at your
authorized Mercedes-Benz dealer as
soon as possible.

ABS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase the traction made
available by the road conditions. 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 vehicle must never be
exploited in a reckless or dangerous
manner which could jeopardize the
user's safety or the safety of others.

Note:

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

97

Brake Assist System (BAS)

Warning!

BAS cannot prevent the natural laws
of physics from acting on the vehicle,
nor can it increase braking efficiency
beyond that afforded by the
condition of the vehicle brakes and
tires or the traction afforded. The
BAS 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 a BAS equipped
vehicle must never be exploited in a
reckless or dangerous manner which
could jeopardize the user's safety or
the safety of others.

The BAS is designed to maximize the
vehicle's braking capability during
emergency braking maneuvers by
having maximum power boost applied
to the brakes more quickly in
emergency braking conditions than
might otherwise be afforded solely by
the driver's braking style. This can help
reduce braking distances over what
ordinary driving and braking style
might do. The BAS complements the
Antilock Brake System (ABS).

To receive the benefit of the system
you must apply continuous full braking
power during the stopping sequence.
Do not reduce brake pedal pressure.

Once the brake pedal is released, the
BAS is deactivated

The malfunction indicator lamps for
the ASR or ESP are combined with the
BAS malfunction indicator lamp.

If the BAS/ASR or BAS/ESP
malfunction indicator lamp comes on
permanently while the engine is
running, a malfunction has been
detected in either system. As a result, it
is possible that now only partial engine
output will be available, and pressing
the accelerator pedal will require more
effort. If the BAS malfunctions, the
brake system functions in the usual
manner, but without BAS.

If the charging voltage falls below 10
volts, the malfunction indicator lamp
comes on and the BAS is switched off.
When the voltage is above this value
again, the malfunction indicator lamp
should go out and the BAS is
operational.

With the ABS malfunctioning, the
BAS, ASR or ESP are also switched
off. Both malfunction indicator lamps
come on with the engine running.

The BAS/ASR or BAS/ESP
malfunction indicator lamp in the
instrument cluster comes on with the
electronic key in steering lock position
2 and should go out with the engine
running.

Have the BAS, ASR or ESP checked at
your authorized Mercedes-Benz dealer
as soon as possible.

98

Electronic Traction System (ETS)

(Model E320 with All Wheel Drive
[AWD]: 4-ETS)

The 4-ETS improves vehicle's ability
to utilize available traction, especially
under slippery road conditions. The
brakes are applied to the spinning
wheel and power is transferred to the
wheel(s) with traction. At
approximately 50 mph (80 km/h), the
ETS switches off at the front wheels,
and at approximately 80 mph (130
km/h) at the rear wheels.
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.

ETS Control

If the yellow BAS/ETS malfunction
indicator lamp comes on while the

ETS warning lamp flashes, with the
engine running, the electronic traction
system is being switched off
temporarily on one ore more wheels
to prevent overheating of the drive
wheel brakes.

If the BAS/ETS malfunction indicator
lamp comes on permanently with the
engine running, a malfunction has
been detected in either system.
If the BAS malfunctions, the brake
system functions in the usual manner,
but without BAS.
Have the BAS or ETS checked at your
authorized Mercedes-Benz dealer as
soon as possible.
With the ABS malfunctioning, the ETS
is also switched off.

Caution!

Model E320 with AWD: 4-ETS
Operational tests with the engine
running can only be conducted on a 2­axle dynamometer. Otherwise the 4­ETS applies the brakes to the spinning
wheels.
If the vehicle is towed with one axle
raised (see Towing the vehicle in
Index), or when testing the parking
brake on a brake test dynamo

meter, the engine must be shut off
(electronic key in steering lock
position 0 or 1). Otherwise, the
electronic traction system will
immediately be engaged and will
apply the brakes.

Notes:
The indicator lamp for the ETS is
combined with that of the BAS
The yellow BAS/ETS malfunction
indicator lamp in the instrument
cluster and the yellow ETS warning
lamp in the speedometer dial come
on with the electronic key in steering
lock position 2. They should go out
with the engine running.
Driving the vehicle with varied size
tires will cause the wheels to rotate at
different speeds, therefore the
acceleration slip regulation may
activate (yellow ETS warning lamp in
speedometer dial comes on). For this
reason, all wheels, including the
spare wheel, must have the same tire
size.

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

99

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
(electronic key in steering lock position
0 or 1). Otherwise, the acceleration slip
regulation will immediately be engaged
and will apply the rear wheel brakes.

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

If the BAS malfunctions, the brake
system functions in the usual manner,
but without BAS.

Have the BAS or 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 warning lamp in
speedometer dial comes on). For this
reason, all wheels, including the spare
wheel, must have the same tire size.

When testing the parking brake on a
