See page 150
The First 1000 Miles (1500 km)
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 1500 km (1000 miles) at moderate vehicle and engine-speeds.
During this period, avoid heavy loads (full throttle driving) and high RPM (no more than 2/3 of maximum permissible speed in each
gear as indicated on the speedometer).
Downshift at proper engine speed!
On vehicles with automatic transmission avoid accelerating by kickdown. It is not recommended to brake the vehicle by manually
shifting to a lower gear. We recommend to select positions "4" (for model 300 SL), "3" or "2" only at moderate speeds (for hill
driving).
After 1500 km (1000 miles) speeds may be gradually increased to the permissible maximum.

Catalytic Converter
Caution!
Warning!
Your MERCEDES-BENZ is equipped
with monolithic type catalytic
converters, an important element in
conjunction with the O2sensor 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.
14
Starting and Turning off the Engine
Before Starting
Engage parking brake and move
gearshift lever to neutral (selector lever
position "P" on automatic transmissions)
Turn key in steering lock to position 2.
The charge indicator lamp should come
on.
Cold Engine
Turn key in steering lock clockwise to
the stop. Do not depress accelerator.
Release key only when the engine is
firing regularly.
Hot Engine
Turn key in steering lock clockwise to
the stop. Do not depress accelerator. 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 only when the vehicle has
stopped moving.
Note:
Vehicles with automatic transmission:
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 neutral
or position "P".
Note:
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.
The charge indicator lamp should go
out as soon as the engine has started.
In areas where temperatures
frequently drop below -25°C (-13°F)
we recommend that an engine block
heater be installed. Your authorized
MERCEDES-BENZ dealer will advise
you on this subject.
15
Driving Instructions
Warning!
Warning!
Power Assistance
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 a lower gear (selector
lever position "4" [for model 300 SL],
"3", "2" or "B" [for model 500 SL] in
the case of automatic transmission).
This helps prevent overheating of the
brakes and reduces brake pad wear. Do
not exceed engine speed limits (see
pages 78 or 80).
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.
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.
The condition of the parking brake
system is checked each time the car is
in the shop for the required
maintenance.
Between maintenance checks, it is a
good practice to apply the parking
brake once or twice while driving at
approximately 50 km/h (30 mph) on a
dry straight road. Apply parking brake
lightly until a slight drag on the wheels
is felt. Keep applying the brake for
about 10 seconds while pulling the release handle out before releasing the
parking brake completely. This practice
will keep the parking brake at
maximum efficiency.
The stop lamps will not come on
when applying the parking brake
only. Perform the procedure in the
previous paragraph only when the
road is clear of other traffic.
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.
All checks and maintenance work on
the brake system should be carried out
by an authorized MERCEDES-BENZ
dealer.
16
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!
Warning!
Do not allow your tires to wear down
too far. With less than 3 mm (1/8 in)
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).
If other than recommended brake
pads are installed, the braking
properties of the vehicle can be
affected to an extent that the safety is
substantially impaired.
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 approx. 2 mm (1/16 in), 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 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, or tire blowout.
17
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
arid apply brakes cautiously in the rain.
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 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.
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 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. 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.
Clutch
Caution!
Resting your foot on the clutch
pedal will cause excessive and
premature wear of the clutch
components.
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
repeatedly when traveling on saltstrewn roads at length. This can bring
road salt impaired braking efficiency
back to normal. A prerequisite is,
however, that this is possible 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.

increasing cooling capacity
If a higher heating or cooling capacity
is required due to extreme outside
temperatures, select a higher blower
setting.
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:
Outside air is drawn in through a filter.
Dust particles (up to a certain size) and
pollen are filtered out
1Temperature Selector
Select the desired temperature with the
temperature selector.
A basic setting in the white field of the
selector is recommended.
The selected temperature is shown in
the indicator window 2. With
conversion switch 3, the selected
