Changing the turn signal bulb
The procedure for changing the bulb is the same on both
sides of the vehicle.
Fig. 220 Turn signal
bulb
Fig. 221 Turn signal
bulb
– Switch off the ignition and the lights. –
Raise the bonnet.
– Pull the rubber cap ⇒ Fig. 220 to remove it.
– Remove the bulb holder by pulling on the grip and turning it an-
ticlockwise ⇒ Fig. 221.
– Replace the blown bulb in the bulb holder (press and turn anti-
clockwise to remove) with a new bulb (press and turn clockwise
to insert).
– Insert the bulb holder into the socket with the tab facing up-
wards and the grip horizontal. Press it against the socket and
turn clockwise. When changing the bulb, you can check the po-
sition of the bulb through the headlight glass.
– Fit the rubber cap and tighten, making sure it fit properly into
the headlight casing.
– Check whether the new bulb is working.
Changing the xenon bulb
The procedure for changing the bulb is the same on both sides of the vehi-
cle.
WARNING
This type of bulb should be changed at a specialised workshop.

286If and when
Removing 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. 224 Luggage com-
partment: Location of the
bolt securing the tail
light unit
Fig. 225 Remove rear
light unit 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 rear lid.
– Prise off the cover with a screwdriver in the slot ⇒ Fig. 224 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 anticlockwise (arrows) 2
.
– Gradually ease the tail light out of the housing ( ⇒ Fig. 225 posi-
tions 3
and 4) by pulling alternately in positions 1 and 2.
– Remove the bulb holder ⇒ page 287.
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 specialised workshop.
Note
Make sure you have a soft cloth ready to place under the glass on the rear
light unit, to avoid any scratches.

296If and when
Jump leads
Jump leads must comply with standard DIN 72553 (see cable manufactur-
er's instructions). The wire cross section must be at least 25 mm 2
for petrol
engines and at least 35 mm 2
for diesel engines.
Note
● The vehicles must not touch each other, otherwise electricity could flow
as soon as the positive terminals are connected.
● The discharged battery must be properly connected to the on-board net-
work.

Fig. 245 Diagram of con-
nections for vehicles
without Start Stop sys-
tem
Fig. 246 Diagram of con-
nections for vehicles
with Start Stop system
Jump lead terminal connections
1. Switch off the ignition of both vehicles ⇒
.
2. For vehicles without Start-Stop system :
– Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 245.
– Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
– Connect one end of the black jump lead to the negative terminal
–
of the vehicle providing assistance B ⇒ Fig. 245.
– Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A
.
3. For vehicles with Start-Stop system :

297
If and when
– Connect one end of the red jump lead to the positive +
termi-
nal of the vehicle with the flat battery A ⇒ Fig. 246.
– Connect the other end of the red jump lead to the positive ter-
minal +
in the vehicle providing assistance B.
– Connect one end of the black jump lead X
to a suitable ground
terminal, a solid piece of metal in the engine block, or to the en-
gine block ⇒ Fig. 246.
– Connect the other end of the black jump lead X
to a solid met-
al component bolted to the engine block or to the engine block
itself of the vehicle with the flat battery. However, connect it to
a point as far as possible from the battery A
.
4. Position the leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting
5. Start the engine of the vehicle with the boosting battery and let it run at idling speed.
6. Start the engine of the vehicle with the flat battery and wait two or three minutes until the engine is “running”.
Removing the jump leads
7. Before you remove the jump leads, switch off the dipped beam headlights (if they are switched on).
8. 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.
9. When the engine is running, disconnect the leads in reverse or- der 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.
WARNING
● Please note the safety warnings referring to working in the engine
compartment ⇒ page 235.
● The battery providing assistance must have the same voltage as the
flat battery (12V) and approximately the same capacity (see imprint on
battery). Failure to comply could result in an explosion.
● Never use jump leads when one of the batteries is frozen. Danger of
explosion! Even after the battery has thawed, battery acid could leak and
cause chemical burns. If a battery freezes, it should be replaced.
● Keep sparks, flames and lighted cigarettes away from batteries, dan-
ger of explosion. Failure to comply could result in an explosion.
● Observe the instructions provided by the manufacturer of the jump
leads.
● Do not connect the negative cable from the other vehicle directly to
the negative terminal of the flat battery. The gas emitted from the battery
could be ignited by sparks. Danger of explosion.
● Do not attach the negative cable from the other vehicle to parts of the
fuel system or to the brake line.
● 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 a short circuit.
● Position the leads in such a way that they cannot come into contact
with any moving parts in the engine compartment.
● Do not lean on the batteries. This could result in chemical burns.
Safety FirstOperating instructionsPractical TipsTechnical Specifications

300If 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 (30 mph).
● 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 driven wheels while the vehicle is being towed.
● If the vehicle has to be towed more than 50 km (30 miles), 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 towline anchorage should always be kept in the vehicle. Please refer
to the notes ⇒ page 299, Tow-starting.
Front towing eyeFig. 247 Fitting the tow-
line anchorage to front of
the vehicle
Fitting the towline anchorage
– Take the towline anchorage from the on-board tool set.
– Remove the front cover by pressing down on the right hand
side.
– Bolt the anchorage to its limit to the left, in the direction of the
arrow ⇒ Fig. 247.
