Advice
●
A short c
ircuit is produced if the battery ter-
minals are bridged, e.g. using metal objects,
cables, etc. Possible consequences of a short
circuit: melting of lead plates, battery explo-
sion and fire, splashing acid.
●
The following is forbidden while working on
the battery: fire and open flames, smoking
and activities that could produce sparks.
Avoid causing sparks when handling cables
or electrical apparatus. Risk of injury in the
event of large sparks.
●
Before working on the electrical system,
you must switch off the engine, the ignition
and all electrical components and disconnect
the cable from the negative terminal (-) of the
battery. To change a bulb, simply switch off
the corresponding light.
●
Never charge a frozen or thawed out bat-
tery. Risk of explosion and acid burns! Re-
place a frozen battery.
●
Never use the jump leads on batteries in
which the electrolyte level is too low. Risk of
explosion and acid burns!
●
Never use a damaged battery. Risk of ex-
plosion! Replace a damaged battery immedi-
ately.
CAUTION
●
Never dis
connect the battery when the igni-
tion is switched on, as the electrical system
(electronic components) of the vehicle could
be damaged. When disconnecting the battery
from the vehicle electrical system, disconnect
its negative terminal (-) first. Only then may
the positiv
e terminal (+) be disconnected.
●
When connecting the battery, first connect
the positive terminal (+) and then the nega-
tive terminal (-). The battery cables must nev-
er be connected to the wrong battery termi-
nals. Risk of burning the electrical installa-
tion!
●
Make sure the battery acid does not come
into contact with the bodywork. Risk of paint-
work damage.
●
Do not expose the battery to direct sunlight
to protect it from ultraviolet radiation.
●
If the vehicle is not used for 3 or 4 weeks,
the battery could run flat. This is because
some components use electricity even in
standby mode (e.g. control units). Prevent the
battery from running flat by disconnecting its
negative terminal or leave it charging at a low
current.
●
If you frequently use the vehicle for short
trips, the battery may not fully charge and
could run flat.
For the sake of the environment
A flat battery is particularly harmful waste for
the envir
onment. It must therefore be dis-
posed of according to current local law.
Note
Replace a battery once it is older than 5
year
s.
Control lamp
If the control lamp is illuminated while the
engine i
s running, the battery is not charg-
ing.
Go to a technical service. Have the car's elec-
trical equipment inspected.
CAUTION
Additionally, if the warning lamp lights up
whi
le driving, the warning lamp also lights
up (cooling system fault). Stop the vehicle
and switch off the engine – Risk of engine
damage!
Lifting the battery cover
