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.

14
Catalytic Converter
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.
Caution!
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.
Warning!
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.
15
Starting and Turning off the Engine
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.
Cold Engine
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”.
If the coolant temperature is very high
(e.g. after hard driving on mountain
roads), do not shut off the engine
immediately, but allow it to run for 1-2
minutes at increased idle speed with
selector lever in position “P” or “N”.
Important!
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.
16
Driving Instructions
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
Caution!
When driving down long and steep
grades, relieve the load on the brakes
by shifting into "3", "2" or "B" (for
models SL 500 and SL 600). This
helps prevent overheating of the brakes
and reduces brake pad wear. Do not
exceed engine speed limits. Refer to
Technical Data for downshift points.
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.
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 affected to an extent
that safe braking is substantially
impaired.
17
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
approximately1/16in (1.5 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. As tread depth
approaches1/16in (1.5 mm), 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. Reduce vehicle speed, avoid track
grooves in the road and apply brakes
cautiously in the rain.
18
Tire Traction
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 whenever the
outside temperatures are 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.
Tire Speed Rating
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.
Parking
Warning!
To reduce the risk of personal
injury as a result of vehicle
movement, before turning off the
engine and leaving the vehicle
always:
1. Keep right foot on brake
pedal.
2. Firmly depress parking
brake pedal.
3. Move the selector lever to
position "P".
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, move selector
lever position " P".
When parking on hills, always set the
parking brake.
19
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, 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 HF-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.
