Always make sure that neither you nor the bat-
tery is electrostatically charged. There is a
build-up of electrostatic charge, e.g.:
by wearing clothing made from synthetic
R
fibers
due to friction between clothing and seats
R
if you push or pull the battery across the
R
carpet or other synthetic materials
if you wipe the battery with a cloth.

WARNING
During the charging process, a battery pro-
duces hydrogen gas. If a short circuit
occurs or sparks are created, the hydrogen
gas can ignite. There is a risk of an explo-
sion.
Make sure that the positive terminal of a
R
connected battery does not come into
contact with vehicle parts.
Never place metal objects or tools on a
R
battery.
It is important that you observe the
R
described order of the battery terminals
when connecting and disconnecting a
battery.
When jump-starting, make sure that the
R
battery poles with identical polarity are
connected.
It is particularly important to observe
R
the described order when connecting and
disconnecting the jumper cables.
Never connect or disconnect the battery
R
terminals while the engine is running.

SmartKey. Check that all the indicator
lamps in the instrument cluster are off.
Otherwise, electronic components, such
as the alternator, may be damaged.
you first remove the negative terminal
R
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
The battery and the cover of the positive
terminal clamp must be installed securely
