WARNING
This type of bulb should be changed at a qualified workshop.

276If and when
Removing the tail light
To change the bulbs you must remove the tail light assem-
bly. Removing the light requires a certain degree of practical
skill.
Fig. 220 Luggage com-
partment: Location of the
bolt securing the tail
light unit
Fig. 221 Removing tail
light from side panel A special retaining screw is used to secure and guide the tail light.
–
Check which of the bulbs is defective.
– Open the tailgate.
– Prise off the cover with a screwdriver in the slot ⇒ fig. 220 1
and remove the cover (with all the retaining clips) from the
opening.
– Carefully loosen the screw located behind the cover with a
screwdriver, turning it anti-clockwise (arrows) 2
.
– Gradually ease the tail light out of the housing ( ⇒ fig. 221 posi-
tions 3
and 4) by pulling alternately in positions 1 and 2.
– Remove the bulb holder ⇒ page 277.
CAUTION
When removing or installing the tail light, take care not to cause any dam-
age.
● Removing the tail light in particular can lead to the paintwork or tail light
becoming damaged. This is another reason why we recommend having the
bulbs changed by a qualified workshop.
Note
Make sure you have a soft cloth ready to place under the glass on the tail
light, to avoid any scratches.

If and when
How to jump start: description
Fig. 241 How to connect
the jump leads
On ⇒ fig. 241 A
shows the flat battery and B the charged bat-
tery.
Jump lead terminal connections
– Switch off the ignition of both vehicles ⇒
.
1. Connect one end of the red jump lead to the positive ⇒ fig. 241
+
terminal of the vehicle with the flat battery ⇒ .
2. Connect the other end of the red jump lead to the positive ter- minal +
in the vehicle providing assistance.
3. Connect one end of the black jump lead to the negative termi- nal -
on the battery of the vehicle providing assistance.
4. Connect the other end of the black jump lead X
to a solid met-
al component which is bolted on to the engine block, or onto the engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery
⇒
.
5. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
7. Start the engine of the vehicle with the flat battery and wait one or two minutes until the engine is running.
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if they are switched on).
9. Turn on the heater blower and heated rear window in the vehi- cle with the flat battery. This helps minimise voltage peaks
which are generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse order to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

290If and when
Do not pull too hard with the towing vehicle and take care to avoid jerking
the tow-rope. When towing on an unpaved road, there is always a risk of
overloading and damaging the anchorage points.
The ignition of the vehicle being towed must be switched on to prevent the
steering wheel from locking and also to allow the use of the turn signals,
horn, windscreen wipers and washers.
As the brake servo does not work if the engine is not running, you must ap-
ply considerably more pressure to the brake pedal than you normally would.
As the power assisted steering does not work if the engine is not running,
you will need more strength to steer than you normally would.
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h.
● Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle must be towed with the front
wheels raised.
Note
● Observe legal requirements when towing or tow-starting.
● Switch on the hazard warning lights of both vehicles. However, observe
any regulations to the contrary.
● For technical reasons, vehicles with an automatic gearbox must not be
tow-started.
● If damage to your vehicle means that there is no lubricant in the gear-
box, you must raise the drive wheels while the vehicle is being towed.
● If the vehicle has to be towed more than 50 km, the front wheels should
be raised during towing, and towing should be carried out by a qualified
person. ●
The steering wheel is locked when the vehicle has no electrical power.
The vehicle must then be towed with the front wheels raised. Towing should
be carried out by a qualified person.
● The towing eye should always be kept in the vehicle. Please refer to the
notes ⇒ page 289, Tow-starting.
Front towing eyeFig. 242 Fitting the tow-
ing eye to front rear of
the vehicle
Fitting the towing eye
– Take the towing ring from the on-board tool set.
– Remove the front cover by pressing down on the right hand
side.
– Bolt the eye to its limit to the left, in the direction of the arrow
