BATTERY: troubleshooting (2/2)
Attach the positive lead (+) A to termi-
nal 3, then to terminal 2 (+) of the bat-
tery supplying the current.
Attach negative lead (–) B to terminal 1
(–) of the battery supplying the current,
then to earth 4 (–).
Start the engine as normal. As soon as
it is running, disconnect leads A and B
in the reverse order ( 4-3-2-1).
Starting the vehicle using the
battery from another vehicle
If you have to use the battery from an-
other vehicle to start, obtain suitable
jump leads (with a large cross section)
from an approved dealer or, if you al-
ready have jump leads, ensure that
they are in perfect condition.
The two batteries must have an iden-
tical nominal voltage of 12 volts. The
battery supplying the current should
have a capacity (amp-hours, Ah) which
is at least the same as that of the dis-
charged battery.
Ensure that there is no risk of contact
between the two vehicles (risk of short
circuiting when the positive terminals
are connected). Switch off your vehicle
ignition.
Start the engine of the vehicle supply-
ing the current and run it at a moderate
speed.

Check that there is no contact between leads A and B and that the posi-
tive lead A is not touching any metal parts on the vehicle supplying the
current.

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.

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).
is slow to go out or remains lit under
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.
