removal and installation. You should there-

fore have all work involving the battery car-

ried out at a qualified specialist workshop.

WARNING

Work carried out incorrectly on the battery

can lead, for example, to a short circuit and

thus damage the vehicle electronics. This can

lead to function restrictions applying to

safety-relevant systems, e.g. the lighting sys-
tem, ABS (anti-lock braking system) or ESP

(Electronic Stability Program). The operating

safety of your vehicle may be restricted. You

could lose control of the vehicle, for example:

braking

in the event of abrupt steering maneuver

and/or when the vehicle's speed is not

adapted to the road conditions

There is a risk of an accident.
In the event of a short circuit or a similar inci-

dent, contact a qualified specialist workshop

immediately. Do not drive any further. You

should have all work involving the battery car-

ried out at a qualified specialist workshop.

For further information about ABS and ESP

see (

page 64) and (

page 66).

WARNING

Electrostatic build-up can lead to the creation

of sparks, which could ignite the highly explo-

sive gases of a battery. There is a risk of an

explosion.
Before handling the battery, touch the vehicle

body to remove any existing electrostatic

build-up.

The highly flammable gas mixture forms when

charging the battery as well as when jump-

starting.
Always make sure that neither you nor the

battery is electrostatically charged. A build-

up of electrostatic charge can be caused, for

example:

by wearing clothing made from synthetic

fibers

due to friction between clothing and seats

if you push or pull the battery across the

carpet or other synthetic materials

if you wipe the battery with a cloth

WARNING

Battery acid is caustic. There is a risk 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.

WARNING

During the charging process, a battery produ-

ces hydrogen gas. If a short circuit occurs or

sparks are created, the hydrogen gas can

ignite. There is a risk of an explosion.

Make sure that the positive terminal of a

connected battery does not come into con-

tact with vehicle parts.

Never place metal objects or tools on a bat-

tery.

It is important that you observe the descri-

bed order of the battery terminals when

connecting and disconnecting a battery.

When jump-starting, make sure that the

battery poles with identical polarity are

connected.

It is particularly important to observe the

described order when connecting and dis-

connecting the jumper cables.

Never connect or disconnect the battery

terminals while the engine is running.

WARNING

During charging and jump-starting, explosive

gases can escape from the battery. There is a

risk of an explosion.
Particularly avoid fire, open flames, creating

sparks and smoking. Ensure there is sufficient

ventilation while charging and jump-starting.

Do not lean over a battery.
