WARNING
Working on the vehicle battery and the
electrical system can cause corrosion, fire
and electric shocks. Always read and take
into account the following warnings and
safety standards before carrying out any
work:
Before working on the battery, switch off
●
the engine, the ignition and all electrical
devices then disconnect the negative con-
nection on the battery.
Keep children away from acid and the
●
battery itself!
Wear eye protection.
●
Battery acid is very corrosive and caus-
●
tic. It can burn skin and cause blindness.
When handling the battery, protect your-
self from splashes of acids, above all your
hands, arms and face.
Do not smoke and never work close to
●
places exposed to flames or sparks.
Avoid sparks and electrostatic discharg-
●
es when working with cables and electrical
devices.
Never short the battery terminals.
●
Never use a damaged battery. It can ex-
●
plode. Replace a damaged battery imme-
diately.
Replaced damaged or frozen batteries as
●
soon as possible. A flat battery can also
freeze at temperatures close to 0°C
(+32°F).
Checking and refilling levels
CAUTION
Never disconnect the battery if the igni-
●
tion is switched on or if the engine is run-
ning. This could damage the electrical sys-
tem or electronic components.
Do not expose the battery to direct sun-
●
light over a long period of time, as the in-
tense ultraviolet radiation can damage the
battery housing.
If the car is left standing for long periods,
●
protect the battery from extreme cold tem-
perature so that it does not "freeze up" and
become damaged.
Warning lamp
 It lights up
Faulty generator.
Contact a specialised workshop. Have the electrical
system checked.
Disconnect any unnecessary electrical devices. The
generator does not charge the battery while the ve-
hicle is in motion.
Several warning and control lamps light up
for a few seconds when the ignition is switch-
ed on, signalling that the function is being
verified. They will switch off after a few sec-
onds.

Checking the electrolyte level of
the vehicle battery
In the engine compartment: remove

the lid from the vehicle's battery.
The battery's electrolyte level should be
checked regularly in high-mileage vehicles, in
hot countries and in older batteries. Other
batteries do not require maintenance.
Vehicles fitted with the Start-Stop system are
equipped with special batteries. For technical
reasons, the electrolyte level cannot be
checked in these batteries.
