increased impact protection to prevent the vehi-
cle occupants from suffering acid burns should
the battery be damaged in the event of an acci- dent.
In order for the battery to achieve the maximumpossible service life, it should always be suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.
In such cases, have the battery disconnected at aq uali fied specialist workshop .However, you
can also charge the battery with acharger rec-

ded period .Consul taq ualified specialist work-
shop if yo uwishtol eave your vehicle parked up
for along period of time.
Whe nyou park the vehicle, remove the key if you
do not require any electrica lconsumers. The
vehicle will then use very little energy, thus con- serving battery power.

thawed may be reduced. The starting charac-
teristics may be impaired, especially at low tem- peratures. Have the thawed battery checked at
aq ualified specialist workshop. Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apos-
itive terminal and an earth point, in the engine compartment. G

Do not use arapidc harging device to start the vehicle. If yourv ehicle's battery is discharged, the
engine can be jump-started from another vehicl eorfromasecond battery using jump leads.
Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicl eusing adonor battery or ajump-starting device.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Jump-starting may be performe donly using batterie swithanominal voltag eof12V.
R Use only jump leads that have asufficient cross-section and insulated terminal clamps.
R If the battery is full ydischarged, leave the battery that is being used to jump-start connected for
af ew minutes before attempting to start. This charge sthe empty battery alittle.
R Make sure that the two vehicles do not touch.
