Always makesure that neither you northe
battery is electrostatically charged.Abuild-
up of electrostaticcharge can be caused, for
example:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the
carpet or other synthetic materials
Rif you wipe the battery withacloth
GWARNING
During the charging process,abattery
produces hydrogen gas. Ifashort circuit
occurs or sparks are created, the hydrogen
gas can ignite. There isarisk of an explosion.
RMake sure that the positive terminal of a
connected battery does not come into
contact with vehicle parts.
RNever place metal objectsortools on a
battery.
RIt is important that you observe the
described order of the battery terminals
when connecting 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
disconnecting the jumper cables.
RNever connect or disconnectthe battery
terminals while the engine is running.
GWARNING
Batteryacid is caustic. There isarisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries toaqualified
specialist workshop or a
special collection point for
used batteries.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the
MaintenanceBooklet or contactaqualified
