Transfer case
This section is only valid for vehicles with 4-wheel drive (4MATIC). Power is always trans-mitted to both axles.
!Performance tests may only be carried outon a 2-axle dynamometer. The brake systemor transfer case could otherwise be damaged.Contact a qualified specialist workshop for aperformance test.
!Since ESP®engages automatically, the igni-tion must be switched off (the SmartKey orStart/Stop button must be in positionZorG) if
Rthe electrical parking brake is being testedusing a dynamometer
Rthe vehicle is being towed with only oneaxle raised (not permitted for vehicles with4MATIC)
Otherwise, the brake system can be dam-aged.
!Vehicles with 4MATIC must not be towedwith either the front or the rear axle raised, asdoing so will damage the transmission.

Electric parking brake
General notes
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
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 handleC.When the electric parking brake is applied,the redI(USA only) or$(Canadaonly) indicator lamp lights up in the instru-ment cluster.
The electric parking brake can also be appliedwhen the SmartKey is removed.
XTo release:pull handleC.The redI(USA only) or$(Canadaonly) indicator lamp in the instrument clustergoes out.
The electric parking brake can only be released:
Rif the SmartKey is in positionGorHin theignition lock (Ypage 131) or

Parking tips:
RThe way your vehicle is positioned in the park-ing space after parking is dependent on vari-ous factors. These include the position andshape of the vehicles parked in front andbehind it and the conditions of the location. Itmay be the case that Active Parking Assistguides you too far into a parking space, or notfar enough into it. In some cases, it may alsolead you across or onto the curb. If necessary,cancel the parking procedure with ActiveParking Assist.
RYou can also prematurely select transmissionposition[. The vehicle redirects and doesnot drive as far into the parking space. Shouldthe transmission change take place too early,the parking procedure is canceled. A sensibleparking position can no longer be achievedfrom this position.
Exiting a parking space
In order that Active Parking Assist can supportyou when exiting the parking space:
Rthe border of the parking space must be highenough at the front and the rear. A curb stoneis too small, for example.
Rthe border of the parking space must not betoo wide. Your vehicle can be maneuveredinto the parking space at a maximum angle of45° to the starting position.
Ra maneuvering distance of at least 3.3 ft(1.0 m) must be available.
Active Parking Assist can only assist you withexiting a parking space if you have parked thevehicle parallel to the direction of travel usingActive Parking Assist.

You can wash the vehicle in an automatic carwash from the very start.
If the vehicle is very dirty, pre-wash it beforecleaning it in an automatic car wash.
After using an automatic car wash, wipe off waxfrom the windshield and the wiper blades. Thiswill prevent smears and reduce wiping noisescaused by residue on the windshield.
Washing by hand
In some countries, washing by hand is onlyallowed at specially equipped washing bays.Observe the legal requirements in each country.
XDo not use hot water and do not wash thevehicle in direct sunlight.
XUse a soft sponge to clean.
XUse a mild cleaning agent, such as a carshampoo approved by Mercedes-Benz.
XThoroughly hose down the vehicle with a gen-tle jet of water.
XDo not point the water jet directly towards theair inlet.
XUse plenty of water and rinse out the spongefrequently.
XRinse the vehicle with clean water and drythoroughly with a chamois.
XDo not let the cleaning agent dry on the paint-work.
Carefully remove all deposits of road salt assoon as possible when driving in winter.
Power washers
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Always maintain a distance of at least 12 in(30 cm) between the vehicle and the powerwasher nozzle. Information about the correctdistance is available from the equipmentmanufacturer.
Move the power washer nozzle around whencleaning your vehicle.
Do not aim directly at any of the following:
RTires
RDoor gaps, roof gaps, joints, etc.
RElectrical components
RBattery
