CHANGING A WHEEL: jack (1/2)
2
If the vehicle is parked on
the hard shoulder, you must
warn other road users of
your vehicle’s presence
with a warning triangle or with other
devices as per the legislation ap-
plying to the country you are in.
Switch on the hazard war-
ning lights.
Keep the vehicle away from
traffic and on a level surface
where it will not slip.
Apply the parking brake and engage
a gear (first or reverse, or N for se-
quential gearboxes).
Ask all the passengers to leave the
vehicle and keep them away from
traffic.
To prevent any risk of injury
or damage to the vehi-
cle, raise the jack until the
wheel you are replacing is
a maximum of 3 centimetres off the
ground.
If necessary, remove the wheel trim.
Use the wheelbrace 2 to slacken off the
wheel bolts. Position it so as to be able
to push from above.Vehicle equipped with a jack with a
heightener
When changing a front wheel, use the
heightener 1 (figure A).
When changing a rear wheel, remove
the heightener 1 (figure B).

TYRES (2/3)
Tyre pressures
Adhere to the tyre pressures (including
the emergency spare wheel). The tyre
pressures should be checked at least
once a month and additionally before
any long journey (refer to the label af-
fixed to the edge of the driver’s door).
Incorrect tyre pressures
lead to abnormal tyre wear
and unusually hot running.
These are factors which
may seriously affect safety and lead
to:
– poor road holding,
– risk of bursting or tread separa- tion.
The pressure depends on the load
and the speed of use. Adjust the
pressure according to the condi-
tions of use (refer to the label affixed
to the edge of the driver’s door).
Please be aware that a
poorly tightened or miss-
ing valve cap can make the
tyres less airtight and lead
to pressure loss.
Always use valve caps identical to
those fitted originally and tighten
them fully.
Pressures should be checked when the
tyres are cold; ignore higher pressures
which may be reached in hot weather
or following a fast journey.
If tyre pressures cannot be checked
when the tyres are cold, the normal
pressures must be increased by 0.2 to
0.3 bar (or 3 PSI).
Never deflate a hot tyre.
Dual wheel versions
To inflate the outer wheel, it is recom-
mended that the inflation tube is passed
between the two wheels. Vehicle fitted with a tyre pressure
loss warning system
If underinflated (puncture, low pres-
sure, etc.), the warning light
 on
the instrument panel comes on, see
“Tyre pressure loss warning system” in
Section 2.
Changing wheels around
This practice is not recommended.
Emergency spare wheel
Refer to the information on the
“Emergency spare wheel” and
“Changing a wheel” in Section 5.

Connecting a battery charger
The battery charger must be com-
patible with a battery with nominal
voltage of 12 volts.
Do not disconnect the battery when the
engine is running. Follow the instruc-
tions given by the manufacturer of
the battery charger you are using.
When many accessories are fitted to
the vehicle, have them connected to
the + after ignition feed .
BATTERY: troubleshooting (1/2)
To avoid all risk of sparks:
– Ensure that any consumers (cour-
tesy lights, etc.) are switched off
before disconnecting or reconnect-
ing the battery;
– when charging, stop the charger before connecting or disconnecting
the battery;
– to avoid creating a short circuit be- tween the terminals, do not place
metal objects on the battery;
– always wait at least one minute after the engine has been switched off
before disconnecting a battery;
– make sure that you reconnect the battery terminals after refitting.
Special procedures may be
required to charge some
batteries. Contact your ap-
proved dealer.
Avoid all risk of sparks which may
cause an immediate explosion, and
charge the battery in a well venti-
lated area. Risk of serious injury.
Handle the battery with care
as it contains sulphuric acid,
which must not come into
contact with eyes or skin. If
it does, wash the affected area with
plenty of cold water. If necessary,
consult a doctor.
Ensure that naked flames, red hot
objects and sparks do not come into
contact with the battery as there is a
risk of explosion.
Please note when working close to
the engine that it may be hot. In ad-
dition, the engine cooling fan may
start at any moment. The

warning light in the engine compart-
ment reminds you of this.
Risk of injury.

5.38
TOWING: breakdown (1/2)
The steering wheel must be un-
locked and the ignition key must be
in position M (ignition on) to provide
brake lights and hazard warning
lights on the towed vehicle. At night
the vehicle must have its lights on.
Unhitch the trailer, etc., if one is
being towed.
You must observe the towing regu-
lations which apply in the country in
which you are driving: do not exceed
the towing weight for your vehicle.
Contact an approved dealer.
– Use a rigid towing bar.
If a rope or cable is used
(where the law allows this),
the vehicle being towed
must be able to brake.
– A vehicle must not be towed if it is not fit to be driven.
– Avoid accelerating or braking suddenly when towing, as this
may result in damage being
caused to the vehicle.
– When towing a vehicle, it is ad- visable not to exceed 15 mph
(25 km/h).
When the engine is
stopped, steering and brak-
ing assistance are not op-
erational.
Do not remove the key from
the ignition when the vehi-
cle is being towed.
Towing a vehicle with a
sequential gearbox
If the gearbox is stuck in a gear:
– switch on the ignition;
– select neutral with the brake pedal depressed;
– check that the gearbox is in neutral (by pushing the vehicle for example).
If you cannot find neutral you must tow
the vehicle with the front wheels raised.
The vehicle should always be towed
with the ignition switched off.

5.42
The starter is activatedPOSSIBLE CAUSESWHAT TO DO
Warning lights dim or fail to come on;
the starter does not run. Battery terminals disconnected,
oxidised or incorrectly secured.Contact an approved Dealer.
Battery discharged or worn. Connect another battery to the faulty bat-
tery. Refer to the paragraph “Battery: trou-
bleshooting” in Section 5 or replace the bat-
tery if necessary.
Do not push the vehicle if the steering
column is locked.
The engine will not start. Starting conditions are not fulfilled.Refer to the information on “Starting/stop-
ping the engine” in Section 2.
The steering column remains locked. Steering wheel locked. To unlock, move the key and the steer-
ing wheel (refer to the information on the
“Ignition switch” in Section 2).
OPERATING FAULTS (1/5)
The following advice will enable you to carry out quick, temporary repai\
rs. For safety reasons you should always contact
an approved dealer as soon as possible.

5.43
On the roadPOSSIBLE CAUSESWHAT TO DO
Vibrations. Tyres not inflated to the correct pres-
sure, incorrectly balanced or dam-
aged. Check the tyre pressures: if this is not the
problem, have them checked by an ap-
proved dealer.
Coolant boiling in the coolant reservoir. Mechanical fault: damaged cylinder
head gasket.Stop the engine.
Contact an approved Dealer.
Smoke under the bonnet. Short circuit or cooling system leak.Stop, switch off the ignition, stand away
from the vehicle and contact an approved
dealer.
The oil pressure warning light comes
on: while cornering or braking The level is too low. Top up the engine oil (refer to the informa-
tion on “Engine oil level – Topping up/refill-
ing” in Section 4).

acceleration Loss of oil pressure.
Stop the vehicle and contact an approved
Dealer.
White smoke from the exhaust. This is not necessarily a fault. Smoke
may be caused by regeneration of
the particle filter. Refer to the information on “Special fea-
tures of diesel versions” in Section 2.
OPERATING FAULTS (2/5)

5.44
On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating.
Fault with the electric assistance
motor.
Fault in the assistance system. Drive carefully at reduced speed, be aware
of the level of force in the steering wheel
needed to turn the wheels. Consult an ap-
proved dealer
The engine is overheating. The cool-
ant temperature warning light and the
STOP warning light come on. Engine cooling fan not working. Stop the vehicle, switch off the engine and
contact an approved Dealer.
Coolant leaks. Check the coolant reservoir: it should con-
tain fluid. If there is no coolant, consult an
approved Dealer as soon as possible.
OPERATING FAULTS (3/5)
Radiator: If there is a significant lack of coolant, remember that it must
never be topped up using cold coolant while the engine is very warm.
After any procedure on the vehicle which has involved even partial drain\
-
ing of the cooling system, it must be refilled with a new mixture prepar\
ed
in the correct proportions. Reminder: only products approved by our Technical
Department may be used for this purpose.
