Checking and relling levels
●
The battery electrolyte is very corrosive It
can cause skin burns and blindness. When
handling the 12-volt battery, protect your
hands, arms and face in particular from acid
splashes
●
Do not smoke while working and never
work in the vicinity of naked ames or sparks.
●
Avoid sparks caused by electrostatic dis-
charges, just like when handling electric ca-
bles and devices.
●
Never short the battery terminals.
●
Never use damaged 12-volt batteries. They
could explode. If the 12-volt battery is dam-
aged, replace it immediately.
●
Never use a frozen 12 volt battery. When
the battery is discharged, it may freeze at
temperatures close to 0°C (+32°F). If the 12-
volt battery is frozen, replace it immediately.

sunlight for a prolonged period of time.
●
Ultraviolet rays can damage the battery
casing.
NOTICE
If the vehicle is not to be used for a long pe-
riod of time, protect the 12-volt battery from
frost.
●
The battery may freeze and, as a result,
suer irreparable damage.
Note
After starting the engine with a deeply dis-
charged or newly replaced 12-volt battery,
or after a jump start, some system settings
(time, date, personalised comfort settings
and programs) may be incorrectly set or de-
leted. Check and correct these settings once
the battery is suiciently charged.
Note
During the winter, the starting power may be
reduced, and if necessary, the battery should
be charged.
