Important safety notes
GWARNING
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.
RMake sure that the positive terminal of a
connected battery does not come into con- tact with vehicle parts.
RNever place metal objects or tools on a bat-
tery.
RIt is important that you observe the descri-
bed 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 dis-
connecting the jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
Disconnecting the starter battery
!Switch off the engine and remove the key
from the ignition lock. Firstly remove the bat- tery terminals. Otherwise, you could destroy
electronic components such as the alterna-
tor.
Always disconnect the starter battery in the
battery case in the left-hand side footwell
first.
!Always disconnect the battery in the order
described below. Never swap the terminal
clamps. You may otherwise damage the vehi-
cle electronics.
If the vehicle is expected to be out of use for over 3 weeks, disconnect the batteries. This will pre-
vent battery discharge caused by off-load cur-
rent consumption.
