The headlamps are cleaned with a high-
pressure water jet.
Cornering light function
The cornering light function improves the
illumination of the road over a wide angle in
the direction you are turning, enabling better
visibility in tight bends, for example. It can
only be activated if the low-beam headlamps
are switched on and the fog lamp is switched
off.
Active: if you are driving at speeds below
25 mph(40 km/h) and switch on the turn
signals and turn the steering wheel.
Not active: if you are driving at speeds above
25 mph (40 km/h) or switch off the turn signal
and turn the steering wheel to the straight-
ahead position.
The cornering lamp may remain lit for a short
time.
Headlamps and turn signal lamps
fogged up on the inside
The headlamps and the indicator lamps in the
exterior mirrors may fog up on the inside if
there is high atmospheric humidity.
XDrive with the headlamps switched on.
The level of moisture diminishes,
depending on the length of the journey and
the weather conditions (humidity and
temperature).
If the level of moisture does not diminish:
XHave the headlamps checked at a qualified
specialist workshop.

GWarning!
Have the tightening torque checked after
changing a wheel. The wheels could come
loose if they are not tightened to a torque of
96 lb-ft (130 Nm).

Battery
Important safety notes
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
! Have the battery checked regularly at a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
Observe the service intervals in the Service
Booklet or for further information consult a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.
Have the battery charge checked more
frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for
a lengthy period.
Only replace a battery with a battery that has
been recommended by Mercedes-Benz.
Consult an authorized Mercedes-Benz Center
if you wish to leave your vehicle parked up for
a long period of time.
GWarning
Comply with safety precautions and take
protective measures when handling batteries.
Risk of explosionFire, naked flames and
smoking are prohibited
when handling the battery.
Avoid creating sparks.
Battery acid is caustic.
Avoid contact with the skin,
eyes or clothing.
Wear suitable protective
clothing, in particular
gloves, an apron and a face
mask.
Immediately rinse acid
splashes off with clean
water. Consult a doctor if
necessary.
Wear eye protection.Keep children away.Observe this Operator's
Manual.
HEnvironmental note
Do not dispose of batteries in the household
rubbish. Dispose of defective batteries in an
environmentally responsible manner. Take
them to an authorized Mercedes-Benz Center
or to a special collection point for old
batteries.

Jump-startingGWarning
Failure to follow these directions will cause damage to the electronic components, and can lead
to a battery explosion and severe injury or death.
Never lean over batteries while connecting or jump starting. You might get injured.
Battery fluid contains sulfuric acid. Do not allow this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected area with water, and seek medical help if
necessary.
A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or
sparks away from battery, avoid improper connection of jumper cables, smoking, etc.
Attempting to jump start a frozen battery can result in it exploding, causing personal injury.
Read all instructions before proceeding.
! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may
damage the catalytic converter and create a risk of fire.
Do not use a rapid charging device to start the vehicle.
Make sure the jumper cables are not damaged.
Make sure the jumper cables are not touching any other metal objects when they are
connected to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle
or from a second battery using jumper cables.
Observe the following points:
XThe battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.XYou may only jump-start the vehicle when the engine and catalytic converter are cold.XDo not start the engine if the battery is frozen. Let the battery thaw first.XJump-starting may only be performed from batteries with a nominal voltage of 12 V.XOnly use jumper cables that have a sufficient cross-section and insulated terminal clamps.XMake sure that the jumper cables cannot come into contact with parts, such as the pulley
or the fan. These parts move when the engine is started and while it is running.XIf the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
i Jumper cables and further information about jump-starting can be obtained from any
authorized Mercedes-Benz Center.
XMake sure that the two vehicles do not touch.XApply the parking brake.XMove the selector lever to P.XSwitch off all electrical consumers (e.g. radio, blower, etc.).XOpen the hood ( Y page 214).238Jump-startingRoadside Assistance
