Heavy and light loads
G
WARNING
If you rest your foot on the brake pedal while
driving, the braking system can overheat. This
increases the stopping distance and can even
cause the braking system to fail. There is a
risk of an accident.
Never use the brake pedal as a footrest. Never
depress the brake pedal and the accelerator
pedal at the same time.
!
Depressing the brake pedal constantly
results in excessive and premature wear to
the brake pads.
If the brakes have been subjected to a heavy
load, do not stop the vehicle immediately, but
drive on for a short while. This allows the air-
flow to cool the brakes more quickly.
Wet roads
If you have driven for a long time in heavy rain
without braking, there may be a delayed reac-
tion from the brakes when braking for the first
time. This may also occur after the vehicle has
been washed or driven through deep water.
You then have to depress the brake pedal
more firmly. Maintain a greater distance from
the vehicle in front.
After driving on a wet road or having the vehi-
cle washed, brake firmly while paying atten-
tion to the traffic conditions. This will warm up
the brake discs, thereby drying them more
quickly and protecting them against corro-
sion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt
residue may form on the brake discs and
brake pads. This can result in a significantly
longer braking distance.
R
Brake occasionally to remove any possible
salt residue. Make sure that you do not
endanger other road users when doing so.
R
Carefully depress the brake pedal and the
beginning and end of a journey.
R
Maintain a greater distance to the vehicle
ahead.
Servicing the brakes
!
If the red brake warning lamp lights up in
the instrument cluster and you hear a warn-
ing tone while the engine is running, the
brake fluid level may be too low. Observe
additional warning messages in the multi-
function display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked immedi-
ately. This work should be carried out at a
qualified specialist workshop.
!
As the ESP
®
system operates automati-
cally, the engine and the ignition must be
switched off (SmartKey in position 0 or 1 in
the ignition lock) if the electric parking
brake is being tested on a brake dynamom-
eter (maximum 10 seconds).
Braking triggered automatically by ESP
®
may seriously damage the brake system.
All checks and maintenance work on the
brake system must be carried out at a quali-
fied specialist workshop. Have this work car-
ried out at an authorized Mercedes-Benz Cen-
ter.
Have the brake pads replaced and the brake
fluid renewed at a qualified specialist work-
shop, e.g. an authorized Mercedes-Benz Cen-
ter.
If the brake system has only been subject to
moderate loads, you should test the function-
ality of your brakes at regular intervals. To do
so, depress the brake pedal firmly when driv-
ing at a high speed. This improves the grip of
the brake pads.
