Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior dam-
age to the tires or chassis components.
Components damaged in this way may fail
unexpectedly. 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.
!Do not use acidic wheel cleaning productsto remove brake dust. This could damagewheel bolts and brake components.
!Do not park your vehicle for a long periodof time directly after cleaning, particularlyafter cleaning the wheel rim with wheelcleaner. Wheel cleaner can lead to theincreased corrosion of the brake discs andpads. Therefore, drive for a few minutesafter cleaning. By heating up the brakes, thebrake discs and pads dry. The vehicle canthen be parked for a long period of time.
Cleaning the windows
GWARNING
You could become trapped by the wind-
shield wipers if they start moving while
cleaning the windshield or wiper blades.
There is a risk of injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield
or wiper blades.
!Do not use dry cloths, abrasive products,solvents or cleaning agents containing sol-vents to clean the inside of the windows. Donot touch the insides of the windows withhard objects, e.g. an ice scraper or ring.There is otherwise a risk of damaging thewindows.
!Clean the water drainage channels of thewindshield and the rear window at regularintervals. Deposits such as leaves, petalsand pollen may under certain circumstances
prevent water from draining away. This canlead to corrosion damage and damage toelectronic components.
XClean the inside and outside of the windowswith a damp cloth and a cleaning productthat is recommended and approved byMercedes-Benz.
Cleaning wiper blades
GWARNING
If the windshield wipers are set in motion
while you are cleaning the windshield, you
can be trapped by the wiper arm. There is a
risk of injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield.
!Do not pull the wiper blade. Otherwise, thewiper blade could be damaged.
!Do not clean wiper blades too often anddo not rub them too hard. Otherwise, thegraphite coating could be damaged. Thiscould cause wiper noise.
!Hold the wiper arm securely when foldingback. The windshield could be damaged ifthe wiper arm smacks against it suddenly.
XFold the windshield wiper arms away fromthe windshield.
XCarefully clean the wiper blades with adamp cloth.
XFold the windshield wiper arms back againbefore switching on the ignition.
Cleaning the exterior lighting
!Only use cleaning agents or cleaningcloths that are suitable for plastic lenses.Caustic, irritant or otherwise unsuitablecleaning agents or cleaning cloths couldscratch or damage the exterior lighting plas-tic lenses.
XClean the plastic lenses of the exterior lightswith a wet sponge and a mild cleaningagent, e.g. Mercedes-Benz car shampoo orcleaning cloths.

Maintenance and care
Z
RMake sure that the positive terminal of a connected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on a battery.
RIt is important that you observe the described order of the battery terminals when connect-
ing and disconnecting a battery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and disconnect-
ing the jumper cables.
RNever connect or disconnect the battery terminals while the engine is running.
GWARNING
A discharged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is a risk of an explo-
sion.
Allow the frozen battery to thaw out before charging it or jump-starting.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could bedamaged by the non-combusted fuel.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-charged battery has frozen. In this case, you may neither charge the battery nor jump-start thevehicle. The service life of a thawed-out battery may be shorter. The starting characteristics canbe impaired, particularly at low temperatures. Have the thawed-out battery checked at a quali-fied specialist workshop.
Do not start the vehicle using a rapid charging device. If your vehicle's battery is discharged, theengine can be jump-started from another vehicle or from a donor battery using jumper cables.Observe the following points:
RThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,jump-start the vehicle using a donor battery or a jump-starting device.
RYou may only jump-start the vehicle when the engine and exhaust system are cold.
RDo not start the engine if the battery is frozen. Let the battery thaw first.
ROnly jump-start from batteries with a 12 V voltage rating.
ROnly use jumper cables which have a sufficient cross-section and insulated terminal clamps.
RIf the battery is fully discharged, leave the battery that is being used to jump-start connectedfor a few minutes before attempting to start. This charges the battery slightly.
RMake sure that the two vehicles do not touch.
Make sure that:
RThe jumper cables are not damaged.
RBare parts of the terminal clamp do not come into contact with other metal parts while thejumper cables are connected to the battery.
RThe jumper cables cannot come into contact with parts which can move when the engine isrunning, such as the V-belt pulley or the fan.
XSecure the vehicle by applying the electric parking brake.
XShift the transmission to position ].
XMake sure that the ignition is switched off. All indicator lamps in the instrument cluster mustbe off. When using the SmartKey, turn the SmartKey to position
