274 OperationDriving instructionsBrakesTo help prevent brake disk corrosion after 
driving on wet road surfaces (particularly 
salted roads), it is advisable to brake the 
vehicle with considerable force prior to 
parking. The heat generated serves to dry 
the brakes.
If your brake system is normally only sub-
jected to moderate loads, you should occa-
sionally test the effectiveness of the 
brakes by applying above-normal braking 
pressure at higher speeds. This will also 
enhance the grip of the brake pads.If the parking brake is released and the 
brake warning lamp in the instrument clus-
ter stays on, the brake fluid level in the res-
ervoir is too low.
Brake pad wear or a leak in the system may 
be the reason for low brake fluid in the res-
ervoir.
Have the brake system inspected immedi-
ately. Contact an authorized 
Mercedes-Benz Center.
All checks and service work on the brake 
system should be carried out by qualified 
technicians only. Contact an authorized 
Mercedes-Benz Center.
Only install brake pads and brake fluid 
recommended by Mercedes-Benz.Warning!
G
After driving in heavy rain for some time 
without applying the brakes or through wa-
ter deep enough to wet brake components, 
the first braking action may be somewhat 
reduced and increased pedal pressure may 
be necessary to obtain expected braking ef-
fect. 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 effec-
tiveness. It may not be possible to stop the 
vehicle in sufficient time to avoid an acci-
dent.
!Be very careful not to endanger other 
road users when you apply the brakes.
Refer to the description of the Brake 
Assist System (BAS) (
page 81). 
275 Operation
Driving instructions
After hard braking, it is advisable to drive 
on for some time, rather than immediately 
parking, so that the air stream can cool 
down the brakes faster.
Driving off
Apply the brakes to test them briefly after 
driving off. Perform this procedure only 
when the road is clear of other traffic.
Warm up the engine smoothly. Do not 
place full load on the engine until the oper-
ating temperature has been reached.
When starting off on a slippery surface, do 
not allow a drive wheel to spin for an ex-
tended period with the ESP switched off. 
Doing so may cause serious damage to the 
drive train which is not covered by the 
Mercedes-Benz Limited Warranty.
Parking
Warning!
G
If other than recommended brake pads are 
installed, or other than recommended brake 
fluid is used, the braking properties of the 
vehicle can be degraded to an extent that 
safe braking is substantially impaired. This 
could result in an accident.!When driving down long and steep 
grades, relieve the load on the brakes 
by shifting into a lower gear to use the 
engine’s braking power. This helps pre-
vent overheating of the brakes and re-
duces brake pad wear.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or 
leaves can come into contact with the hot 
exhaust system, as these materials could be 
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of inadvertent vehicle movement, be-
fore turning off the engine and leaving the 
vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to 
positionP.
Slowly release brake pedal.
When parked on an incline, turn front 
wheel towards the road curb.
