Driving Instructions
Power assistance
When the engine is not running, the
brake and steering systems are w ith
out power assistance. Under these cir
cumstances, a much greater effort is
necessary to stop or steer the vehicle.
Brakes
Caution!
When driving down long and steep
grades, relieve the brakes by shifting
into “3 ” or “2”. This helps prevent
overheating of the brakes and reduces
brake pad wear. Do not exceed
engine speed limits (see page 60).
After hard braking it is advisable to
drive on for some time so the air
stream will cool down the brakes
faster.
Warning!
After driving in heavy rain for
some tim e without applying the
brakes or through water deep
enough to wet brake com ponents,
the first braking action may be
som ewhat reduced and increased
pedal pressure may be necessary.
Be sure to maintain a safe distan
ce from vehicles in front.
This condition of the parking brake
system is checked each time the car is
in the shop for the required mainte
nance.
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 brake lightly
until a slight drag on the wheels is felt.
Keep applying brake for about 10 sec
onds while pulling the release handle
out before releasing the parking brake
completely. This practice will keep the
parking brake at maximum efficiency.
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.
If the parking brake is released and
the brake warning lamp in the instru
ment 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.
W arning!
The stop lamps will not com e 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
prem ature wear of the brake pads.
W arning!
If other than recomm ended brake
pads are installed, the braking
properties of the vehicle can be
affected to an extent that the
safety is substantially impaired.
