take advantage of engine braking. For thisyou must first activate manual gearshifting.This helps you to avoid overheating thebrakes and wearing them out excessively.
When you take advantage of engine braking,it is possible that a drive wheel will notrotate for some time, e.g. on a slippery roadsurface. This could cause damage to thedrive train. This type of damage is not cov-ered by the Mercedes-Benz warranty.
Briefly depressing the accelerator pedal ondownhill gradients while the manual drive pro-gramMis temporarily activated: the automatictransmission may switch to the last activeautomatic drive programEorS. The automatictransmission may shift to a higher gear. Thiscan reduce the engine's braking effect.
Heavy and light loads
GWARNING
If you rest your foot on the brake pedal
while driving, the braking system can over-
heat. 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 constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately.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 rainwithout braking, there may be a delayed reac-tion from the brakes when braking for the firsttime. This may also occur after the vehicle hasbeen washed or driven through deep water.
You have to depress the brake pedal morefirmly. Maintain a greater distance from thevehicle in front.
After driving on a wet road or having the vehi-cle washed, brake firmly while paying attentionto the traffic conditions. This will warm up the
brake discs, thereby drying them more quicklyand protecting them against corrosion.
Limited braking performance on salt-
treated roads
If you drive on salted roads, a layer of salt resi-due may form on the brake discs and brakepads. This can result in a significantly longerbraking distance.
RIn order to prevent any salt build-up, applythe brakes occasionally while paying atten-tion to the traffic conditions.
RCarefully depress the brake pedal and thebeginning and end of a journey.
RMaintain a greater distance to the vehicleahead.
Servicing the brakes
!The brake fluid level may be too low, if:
Rif the red brake warning lamp lights up inthe instrument cluster and
Ryou hear a warning tone while the engineis running
Observe additional warning messages in themultifunction display.
The brake fluid level may be too low due tobrake pad wear or leaking brake lines.
Have the brake system checked immedi-ately. Consult a qualified specialist work-shop to arrange this.
!A function or performance test should onlybe carried out on a 2-axle dynamometer. Ifyou wish to operate the vehicle on such adynamometer, please consult a qualifiedspecialist workshop in advance. You couldotherwise damage the drive train or thebrake system.
!As the ESP®system operates automati-cally, the engine and the ignition must beswitched off (the SmartKey must be in posi-tion
