Rrelease the parking brake.
Rshift the automatic transmission out of the
parking positionP.
Rstart the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
The function of the electric parking brake isdependent on the on-board voltage. If the on-board voltage is low or there is a malfunction inthe system, it may not be possible to apply thereleased parking brake.
XIf this happens, park the vehicle on levelground only and secure it to prevent it fromrolling away.
XShift the transmission to position ].
It may not be possible to release an appliedparking brake if the on-board voltage is low orthere is a malfunction in the system. Contact aqualified specialist workshop.
The electric parking brake performs a functiontest at regular intervals while the engine isswitched off. The sounds that can be heard whilethis is occurring are normal.
Applying or releasing manually
XTo apply:push handle C.When the electric parking brake is applied,the red I(USA only) or $(Canadaonly) indicator lamp lights up in the instru-ment cluster.
The electric parking brake can also be appliedwhen the SmartKey is removed.
XTo release:pull handle C.The red I(USA only) or $(Canadaonly) indicator lamp in the instrument clustergoes out.
The electric parking brake can only be released:
Rif the SmartKey is in position Gor Hin theignition lock (Ypage 131) or

This helps you to avoid overheating thebrakes and wearing them out excessively.
When you take advantage of engine braking, adrive wheel may not turn for some time, e.g.on a slippery road surface. This could causedamage to the drive train. This type of damageis not covered by the Mercedes-Benz war-ranty.
Heavy and light loads
GWARNING
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 constantlyresults in excessive and premature wear tothe brake pads.
If the brakes have been subjected to a heavyload, do not stop the vehicle immediately. Driveon for a short while. This allows the airflow tocool 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 vehiclewashed, brake firmly while paying attention tothe traffic conditions. This will warm up thebrake 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, apply thebrakes occasionally while paying attention tothe 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 engine isrunning
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 immediately.Consult a qualified specialist workshop toarrange this.
!Vehicles with 4MATIC:function or per-formance tests may only be carried out on a 2-axle dynamometer. If you wish to operate thevehicle on such a dynamometer, please con-sult a qualified specialist workshop inadvance. You could otherwise damage thedrive train or the brake system.
!Vehicles with 4MATIC:the ESP®systemoperates automatically. If the electric parkingbrake is tested on a brake dynamometer, theengine and ignition must be switched off: turnthe SmartKey in the ignition lock to position
