Advice
Different control lamps may light up after
c
onnectin
g the b
attery and switching the ig-
nition on. They will be turned off after a short
trip at a speed of between 15-20 km/h
(10-12 mph). If the warning indicators remain
lit, please visit a specialised workshop to
have the vehicle checked.
If the battery has been disconnected for a
long time, it is possible that the next service
date is not displayed or calculated correctly

Automatic device disconnection
The intelligent vehicle electrical system auto-
matically implements a range of measures to
prevent the battery from discharging when
high demands are made on it:
●
The idling speed is increased so that the al-
ternator provides more electricity.
●
Where necessary, the power to the most
powerful devices is reduced or even com-
pletely disconnected.
●
On starting the engine, the power supply
from the 12-volt power sockets and the ciga-
rette lighter may be interrupted for a short
time.
The on-board management program cannot
always prevent the battery from running flat.
For example, if the ignition is left on for a
long period with the engine off or if the side
lights or parking lights are left on while the
vehicle is stationary.
Why the battery runs flat:
●
When stationary for a long time without
starting the engine, particularly if the ignition
is switched on.
●
Use of electrical devices with the engine
switched off.
WARNING
Incorrectly securing the battery or using the
wrong b
attery can cause short-circuits, fire
and serious injuries.
●
Always use only maintenance-free batter-
ies, protected to prevent a leak, and whose
properties, specifications and size corre-
spond to the standard battery.
WARNING
A highly explosive mixture of gases is re-
lea
sed when the battery is under charge.
●
The batteries should be charged in a well-
ventilated room only.
●
Never charge a frozen or recently thawed
battery. A flat battery can also freeze at tem-
peratures close to 0 °C (+32 °F).
●
Always replace a battery which has frozen.
●
Battery cables not correctly connected may
cause a short circuit. Reconnect first the posi-
tive cable and then the negative cable.
CAUTION
●
Never dis
connect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
●
Never plug accessories that supply current,
such as solar panels or a battery charger, to
the 12-volt power socket or the cigarette
lighter. This could damage the vehicle's elec-
trical system.
For the sake of the environment
Dispose of the battery in an environment-
friendly manner
. Batteries contain toxic sub-
stances such as sulphuric acid and lead.
For the sake of the environment
Battery acid can contaminate the environ-
ment. Co
llect any spilt service fluids and dis-
pose of them correctly.
