Technical data
•
Do not expose the battery to direct sunlight over a long period of
time, as the intense ul traviolet radiation can affect the battery
housing.
•
If the car is left standing for long periods, protect the battery
from extreme cold temperature so that it does not “freeze up” and
become damaged.
Charging the battery
Terminals for charging the battery are fitted in the engine
compartment.– Note the warnings ⇒ in “Important safety warnings
for handling a car battery” on page 240 and ⇒.
– Switch off all electrical equi pment. Remove the ignition
key.
– Open the bonnet ⇒page 230 .
– Open the red cap on the positive terminal ⇒fig. 229.
– Follow the correct procedure for connecting the charger cables to the jump-start terminals (terminal with red cap
= “positive”, terminal with hexagon = “negative”). – Now connect the battery charger to the mains and switch
on.
– After charging the battery: switch off the battery charger and disconnect the mains cable.
– Now disconnect the charger cables.
– Refit the red cap onto the positive terminal.
– Close the bonnet ⇒page 232 .
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must be thawed before charging ⇒.
However, it is advisable to replace the battery if it has frozen,
because the ice can crack the batte ry casing and allow the battery
acid to escape.
Charging the battery
Important: Before you charge the battery make sure you read the
manufacturer's instructions for using the battery charger.
When charging with a low current (for instance with a small battery
charger ) the battery does not have to be disconnected. The battery
must not be opened while you are charging it.
Fast-charging the battery
For technical reasons it is not permissible to fast-charge the battery
using charging devices with an ou tput voltage higher than 14.8 V.
WARNING
Never charge a frozen battery – it could explode.
Note
Use only the terminals in the engine compartment to charge the
battery.

If necessary, the engine can be started by connecting it to
the battery of another vehicle.If the engine should ever fail to start because of a discharged
battery, the battery can be connected to the battery of another
vehicle to start the engine. Suitable jump leads are required.
Both batteries must be rated at 12 Volts. The capacity (Ah) of the
booster battery should not be significantly lower than that of the
discharged battery. Jump leads
The jump leads must be
heavy enough to carry the starter current.
Refer to the details given by the manufacturer.
Only use jump leads with insulated battery clamps.
Positive cable – usually red
Negative cable – usually black
WARNING
•
When it is discharged the battery can freeze at temperatures
around 0°C. A frozen battery must first be thawed out before
connecting the jump leads, as it could otherwise explode.
•
Please note the safety warnings referring to working in the
engine compartment ⇒page 231 .Note
•
There must be no contact between the two vehicles as otherwise
current could flow as soon as the positive terminals are connected.
•
The discharged battery must be properly connected to the
vehicle's electrical system.
•
Switch off the car telephone if necessary. Details will be given in
the manufacturer's instructions for the car telephone.
