•
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.

= “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.
•

266Starting the engine
The two jump leads must be connected in the correct
sequence.The jump-start terminals are located in the engine compart-
ment ⇒fig. 248.
Connecting the positive terminals with the
positive lead (red)
– Open the red cap on the positive terminal ⇒fig. 248.
1. Connect one end of the lead to the jump-start terminal
⇒ fig. 249 (terminal under red cap = “positive”) of the
vehicle with the flat battery . 2. Connect the other end of the positive lead to the positive
terminal of the boosting battery .
Connecting negative terminals with the
negative lead (black)
3. Connect one end of the negative lead to the negative terminal of the boosting battery .
4. Connect the other end of the lead to the jump-start
terminal (terminal with hexagon = “negative”) of the
vehicle with the flat battery .
Starting the engine
– Start the engine of the vehicle with the boosting battery and let it run at idling speed.
– Now start the engine of the vehicle with the discharged battery .
– If the engine fails to start: do not operate the starter for longer than 10 seconds. Wait for about 30 seconds and
try again.
– When the engine is running, disconnect the leads in exactly the opposite sequence to that described above.
– Refit the red cap onto the positive terminal.
The battery is vented to the outs ide to prevent gases entering the
vehicle's interior.
Connect the battery clamps so they have good metal-to-metal
contact with the re spective terminals.
WARNING
•
The non-insulated parts of the battery clamps must not be
allowed to touch. The jump lead attached to the positive battery

terminal must not touch metal parts of the vehicle: this can cause
short circuiting.
•
Do not bend over the batteries – risk of acid burns.
•
The screw plugs on the battery ce
lls must be screwed in firmly.
•
Keep sparks, flame and lighted cigarettes away from batteries:
the gases given off can cause an explosion.
•
If jump-starting another vehicle, position the jump leads in
such a way that they cannot come into contact with any moving
parts in the engine compart ment of the other vehicle.Caution
Please note that the above method of connecting the leads is meant
for jump-starting your vehicle. If jump-starting another vehicle, you
should not connect the negative lead (–) to the negative terminal of
the discharged battery, but directly to the engine block or a solid
metal part bolted to the engine bl ock. If the battery of the other
vehicle does not have a gas vent, there is a risk that a mixture of
oxygen and hydrogen gas can accumulate and cause an
explosion.Tow-starting and towing awayGeneral notes
Points to observe when tow-starting or towing awayIf you use a towrope:
Notes for the driver of the towing vehicle
– The towrope must be taut before driving off. – Engage the clutch very gently when starting to move; on
vehicles with automatic gearbox press the accelerator
slowly.
Notes for the driver of the towed vehicle
– The ignition should be switched on so that the turn signals, horn, windscreen wipers and washers can be
used. Please ensure that the steering wheel is unlocked
when you switch on the ignition, and that it moves freely.
–Put gear lever in neutral (manual gearbox) or move
selector lever to position N (automatic gearbox).
– The brake servo and power steering only work when the engine is running. Considerably more effort is required
on the brake pedal and steering wheel when the engine
is switched off.
– Ensure that the towrope remains taut at all times when towing.
Towrope or towbar
It is easier and safer to tow a vehicle with a tow bar. You should only
use a tow rope if you do not have a towbar.
A towrope should be slightly elasti c to reduce the loading on both
vehicles. It is advisable to use a towrope made of synthetic fibre or
similar material.
Attach the tow-rope or tow-bar only to the towing anchorages
intended for this purpose ⇒page 268 or ⇒page 269 .
Driving technique
Towing requires some experience – especially when using a
tow rope . Both drivers should be familiar with the technique required
for towing. Inexperienced drivers sh ould not attempt to tow-start or
tow away another vehicle.

Rear towline anchorage
Vehicles which do not have a factory-fitted towing
bracket* have a towline anchor age on the right side of the
rear bumper.Vehicles with towline anchorage
– Take the towline anchorage out of the vehicle's tool kit.
– To detach the cover cap from the bumper, firmly press
the lower part of the cap inwards to release it ⇒fig. 252.
– Screw the towline anchorage firmly all the way into the screw connection.
Vehicles with towing bracket*
– Fit the towing bracket if it is not already in place.
– Attach the towbar or the towrope to the towing bracket.After use, unscrew the towline anchorage and put it back in the
toolbox. Replace the cap in the screw connection. The towline
anchorage should always be kept in the vehicle.
Vehicles which have a factory-fitted towing bracket* do not have a
screw connection at the rear for the towline anchorage.
WARNING
•
If the towline anchorage is not screwed in as far as the stop,
there is a risk of the screw connection shearing off during towing
(accident risk).
•
If your car has a towing bracket*, please use only special tow
bars with suitable attachments (i .e. tow bars which are specially
designed for use with towing brac kets) to avoid damage to the
coupling equipment.
•
If your car has a towing bracket*, please use only special
towing ropes (risk of accident).
To w - s t a r t i n g
As a general rule, tow-s tarting is not recommended.– Engage 2nd or 3rd gear before moving off.
– Press the clutch and hold the pedal down.
– Switch on the ignition.
– Once both vehicles are moving, release the clutch.
– As soon as the engine starts: press the clutch and put the
gear lever in neutral.If the engine will not start, it is best to try starting it using the
battery of another vehicle ⇒page 265 before attempting to tow
start. You should only try to tow-start the engine if jump-starting is
not successful. Tow-starting is an attempt to start the engine via the
movement of the wheels.
When tow-starting a vehicle with a petrol engine, do not tow it more
than a short distance, otherwise unburnt fuel can enter the catalytic
converter and cause damage.
For technical reasons, it is not possible to tow-start a vehicle with
automatic gearbox .
