Changing a wheel
Introduction
Some vehicle versions and models do not have a factory-fitted jack or box
spanner. In this case, we recommend consulting a Specialised workshop to
change the wheel.
You should only change the wheels yourself if the vehicle is parked in a safe
place, you are familiar with the procedure and you have all the necessary
tools! Otherwise, you should seek professional assistance.

● Vehicle key set ⇒ page 28
● Wheels and tyres ⇒ page 210
● In case of emergency ⇒ page 240
● Vehicle tools ⇒ page 246
● Wheel trims ⇒ page 248
WARNING
Changing a wheel can be dangerous, especially on the hard shoulder.
Please observe the following rules to minimise the risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to change a wheel.
● When changing a wheel, keep all passengers and particularly chil-
dren a safe distance away from the work area.
● Turn on the hazard warning lights to warn other road users.
● Ensure the ground on which you park is flat and solid. If necessary,
support the jack on a wide solid base.
WARNING (Continued)
● If you are changing a wheel yourself, you should be familiar with the
required procedure. Otherwise, you should seek professional assistance.
● Only use suitable tools that are not damaged when changing a wheel.
● Always stop the engine, apply the handbrake lever firmly and place
the selector lever in position P, or engage a gear for a manual gearbox to
reduce the risk of the vehicle moving accidentally.
● Have the tightening torque of the wheel bolts checked as soon as
possible with a reliable torque wrench.

Anti-puncture kit*
Introduction
The Tyre Mobility Set* will reliably seal punctures caused by the penetration
of a foreign body of up to about 4 mm in diameter. Do not remove foreign
objects, e.g. screws or nails, from the tyre.
After inserting the sealant residue in the tyre, you must again check the tyre
pressure about 10 minutes after starting the engine.
You should only use the tire mobility set if the vehicle is parked in a safe
place, you are familiar with the procedure and you have the necessary tire
mobility set! Otherwise, you should seek professional assistance.
The tyre sealant must not be used in the following cases:
● If the wheel rim has been damaged.
● In outside temperatures below -20 °C (-4 °F).
● In the event of cuts or perforations in the tyre greater than 4 mm.
● If you have been driving with very low pressure or a completely flat tyre.
● If the sealant bottle has passes its use by date.
Additional information and warnings:

WARNING
Using the tire mobility set can be dangerous, especially when filling the
tyre at the roadside. Please observe the following rules to minimise the
risk of injury:
● Stop the vehicle safely as soon as possible. Park your vehicle as safe
distance from surrounding traffic to fill the tyre.
● Ensure the ground on which you park is flat and solid.
● All passengers and particularly children must keep a safe distance
from the work area.
● Turn on the hazard warning lights to warn other road users.
● Use the tire mobility set only if you are familiar with the necessary
procedure. Otherwise, you should seek professional assistance.
● The tire mobility set is intended for temporary, emergency use only.
Use only until you can reach the nearest specialised workshop.
● Replace the repaired tyre with the tire mobility set as soon as possi-
ble.
● The sealant is a health hazard and must be cleaned immediately if it
comes into contact with the skin.
● Always keep the tire mobility set out of the reach of small children.
● Never use the approved jack, even if it has been approved for your ve-
hicle.
● Always stop the engine, apply the handbrake lever firmly and engage
gear if using a manual gearbox, in order to reduce the risk of vehicle in-
voluntary movement.
WARNING
A tyre filled with sealant does not have the same performance properties
as a conventional tyre.
● Never drive faster than 80 km/h (50 mph). 

Practical information
Fuses
Introduction
Due to the constant update of vehicles, fuse assignments depending on
equipment and the use of the same fuse for various electrical components,
at the time of printing this manual it is not possible to provide an up-to-date
summary of the electrical components fuse positions. For detailed informa-
tion about the fuse positions, please consult a Technical Service.
In general, a fuse can be assigned to various electrical components. Like-
wise, an electrical component can be protected by several fuses.
Only replace fuses when the cause of the problem has been solved. +If a
newly inserted fuse blows after a short time, you must have the electrical
system checked by a Specialised workshop as soon as possible.
Additional information and warnings:
● Working in the engine compartment ⇒ page 180
WARNING
The high voltages in the electrical system can give serious electrical
shocks, causing burns and even death!
● Never touch the electrical wiring of the ignition system.
● Take care not to cause short circuits in the electrical system.
WARNING
Using unsuitable fuses, repairing fuses or bridging a current circuit with-
out fuses can cause a fire and serious injury.
● Never use a fuse with a higher value. Only replace fuses with a fuse of
the same amperage (same colour and markings) and size.
● Never repair a fuse.
● Never replace a fuse by a metal strip, staple or similar.
CAUTION
● To avoid damage to the vehicles electric system, before replacing a fuse
turn off the ignition, the lights and all electrical elements and remove the
keys from the ignition.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another part of the electrical system.
● Protect the fuse boxes when open to avoid the entry of dust or humidity.
Dirt and humidity inside fuse boxes can cause damage to the electrical sys-
tem.
Note
One single consumer could have more than one fuse.
Note
Several consumers could run over one single fuse. 

Information for replacing bulbs
Checklist
To replace a bulb, carry out the following operations always in the order giv-
en ⇒ 
:
1. Park the vehicle a safe distance from traffic and on suitable ground.
2. Apply the handbrake firmly ⇒ page 134.
3. Turn the light switch to position 0 ⇒ page 84.
4. Move the gear lever into the neutral position ⇒ page 84.
5. Stop the engine and remove the key from the ignition ⇒ page 119.
6. Automatic gearbox: move the selector lever to position P
⇒ page 124.
7. Manual gearbox: Select a gear ⇒ page 124.
8. Allow the corresponding bulb to cool.
9. Visually inspect fuses to see if any are blown ⇒ page 261.
10. Replace the bulb according to the instructions ⇒ 
. Bulbs should
only be replaced by new identical models. Bulb information is dis-
played on the bulb socket or on the bulb itself.
11. In general, never touch the bulb glass directly. The heat of the bulb would cause the fingerprint to evaporate and condense on the reflec-
tor. This will impair the brightness of the headlight.
12. Check if the new bulb is working. If the bulb is not working, it maynot have been correctly fitted, it could be damaged or the connector
may not be correctly connected.
13. Every time a bulb for the headlights is replaced, visit a specialised workshop to check the headlights.
WARNING
Failure to follow the checklist prepared for your own safety could lead to
accidents and severe injuries.
● Always complete the operations given in the checklist and observe
the general rules of safety.
CAUTION
Always remove and fit headlights carefully to avoid damage to the paint-
work and other vehicle parts. 

Towing and tow starting
Introduction
When towing or tow starting, respect the legal requirements.
For technical reasons, it is not possible to tow a vehicle if the battery is flat.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Electronic power control and exhaust gases purification system
⇒  page 236
WARNING
A vehicle with a flat battery should never be towed.
● Never remove the key from the ignition lock. Otherwise, the steering
wheel lock could suddenly lock. Then the vehicle will be uncontrollable.
You may lose control of the vehicle and there is a risk of serious accident.
WARNING
When towing the vehicle, the handling and braking efficiency change
considerably. Please observe the following instructions to minimise the
risk of serious accidents and injury:
● As the driver of the vehicle being towed:
– The brake must be depressed must harder as the brake servo does
not operate. Always remain aware to avoid collision with the towing
vehicle.
– More strength is required at the steering wheel as the power steer-
ing does not operate when the engine is switched off.
● As the driver of the towing vehicle:
– Accelerate gently and carefully.
– Avoid sudden braking and manoeuvres.
– Brake well in advance than usual and brake gently.
CAUTION
● Carefully fit and remove the towing ring and its cover to avoid damage to
the vehicle (for example, paintwork).
● When towing, fuel could enter the catalytic converter and cause dam-
age!
Note
Fitting a towline anchorage to the rear bumper is not possible. The vehicle is
not suitable for towing other vehicles. 
