110Driving
Driving and parking

The electrolyte of the battery is cor-
rosive. Avoid contact with skin, eyes
or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Immediately rinse electrolyte
splashes off with clean water. Con-
tact a physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide
increased impact protection to prevent vehicle
occupants from suffering acid burns should the
battery be damaged in the event of an accident.
In order for the battery to achieve the maximum
possible service life, it must always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In this case, have the battery disconnected at a
qualified specialist workshop. You can also
charge the battery with a special charger rec-
ommended by Mercedes-Benz. Contact a quali- fied specialist workshop for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly for
short trips or if you leave it standing idle for a
lengthy period. Consult a qualified specialist
workshop if you wish to leave your vehicle
parked for a long period of time.
When you use the SmartKey in the ignition and
you park the car, remove the SmartKey if you do not require any electrical consumers. The vehi-
cle will then use very little energy, thus conserv-
ing battery power.
If the power supply has been interrupted, e.g. if
you reconnect the battery, you will have to:
Rreset the function for automatically folding
the exterior mirrors in/out by folding the mir-
rors out once (
Ypage 87)
Rreset the side windows, see (Ypage 77)
Charging the battery
!
Only use battery chargers with a maximum
charging voltage of 14.4 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment (
Ypage 251).
XOpen the hood.
XConnect the battery charger to the positive
terminal and ground point in the same order
as when connecting the donor battery in the
jump-starting procedure (
Ypage 251).
Keep away from fire and open flames. Do not
lean over a battery. Never charge the battery if it
is still installed in the vehicle, unless you use a
battery charger which has been tested and
approved by Mercedes-Benz. A battery charger
unit specially adapted for Mercedes-Benz vehi-
cles and tested and approved by Mercedes-
Benz is available as an accessory. It permits the
charging of the battery in its installed position.
Contact an authorized Mercedes-Benz Center
for further information and availability. Read the
battery charger's operating instructions before
charging the battery.
Do not charge a battery which has been
removed at low temperatures with a battery
charger. Allow the battery to warm up gently
first, if necessary. Otherwise, the service life can
be shortened and the starting characteristics
impaired, especially at low temperatures.
Jump-starting
XFor the jump-starting procedure, use only the jump-starting connection point in the engine com- partment, consisting of a positive terminal and a ground point.
Jump-starting251
Breakdown assistance

!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
XDo not start the vehicle using a rapid charging device.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle or
from a donor battery using jumper cables.
The 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.
Observe the following during the jump-starting procedure:
Rthe jumper cables must not come into contact with parts that can move when the engine is
running, such as the V-belt pulley or the fan.
Rnon-insulated parts of the terminal clamps must not come into contact with other metal parts
while the jumper cables are connected to the battery and the jump-starting connection point.
Ronly use jumper cables that are not damaged and have a sufficient cross-section and insulated
terminal clamps.
Rjump-starting may be performed only using batteries with a nominal voltage of 12 V.
Ryou may only jump-start the vehicle when the engine and exhaust system are cold.
Rthe vehicles must not touch each other.
RIf 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 battery slightly.
XSecure the vehicle by applying the electric parking brake.
XShift the transmission to position j.
XMake sure the ignition and all electrical consumers are switched off.
All indicator lamps in the instrument cluster must be off. When using the SmartKey, turn the
SmartKey to positionuin the ignition lock and remove it (
Ypage 106).
XOpen the hood.
iRight-hand-drive vehicle: the jump-starting connection points may be located on the other
side of the vehicle.
