Warning!
The stop lamps will not come
on when applying the parking
brake only. Perform the pro­
cedure in the previous para­
graph 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 signifi­
cantly reducing their effec­
tiveness. 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
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, the
braking properties of the ve­
hicle can be affected to an
extent that the safety is sub­
stantially 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
('/ i 6 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.
