lit, please visit a specialised workshop to
have the vehicle checked.

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 battery can cause shor
t-circuits,
fire and serious injuries.
●
Always use only maintenance-free bat-
teries, protected to prevent a leak, and
whose properties, specifications and size
correspond to the standard battery.
WARNING
A highly explosive mixture of gases is re-
leased when the battery is under char
ge.
●
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
temperatures close to 0°C (+32°F).
●
Always replace a battery which has fro-
zen.
●
Battery cables not correctly connected
may cause a short circuit. Reconnect first
the positive cable and then the negative
cable.
CAUTION
●
Never disconnect the batt
ery if the igni-
tion is switched on or if the engine is run-
ning. This could damage the electrical sys-
tem or electronic components.
●
Never plug accessories that supply cur-
rent, such as solar panels or a battery
charger, to the 12-volt power socket or the
cigarette lighter. This could damage the
vehicle's electrical system.
For the sake of the environment
Dispose of the battery in an environment-
friendly manner. Batteries cont
ain toxic
substances such as sulphuric acid and
lead.
For the sake of the environment
Battery acid can contaminate the environ-
ment. Collect any spilt service fluids and
dispose of them correctly.
