Operating faults
The steering may become stiff when
driving or when the steering wheel is
turned repeatedly. This is due to the
power assistance overheating. In this
case, it must be allowed to cool down.Power-assisted steering
Variable power-assisted steering
The variable power-assisted steering
system is equipped with an electronic
control system which alters the level of
assistance to suit the vehicle speed.
Steering is made easier during parking
manoeuvres (for added comfort) whilst
the force needed to steer increases
progressively as the speed rises (for
enhanced safety at high speeds).
STEERING WHEEL/POWER-ASSISTED STEERING
Height and reach adjustment
Pull lever 1 and move the steering
wheel to the required position.
Then, push the lever back fully, beyond
the point of resistance to lock the steer-
ing wheel.
Make sure that the steering wheel is
correctly locked.
For safety reasons, only
adjust the steering wheel
when the vehicle is station-
ary.
Never leave the steering wheel at
full lock while stationary.

Never switch off the igni-
tion when travelling down-
hill, and avoid doing so in
normal driving (assistance
is not provided).
With the engine switched off, or if
there is a system fault, it is still pos-
sible to turn the steering wheel. The
force required will be greater.

Headlight washers
Headlights on
On equipped vehicles, hold stalk 1
pulled towards you for about 1 second,
and the headlight washers and wind-
screen washers will be activated at the
same time.
Note: when the minimum windscreen
washer fluid level is reached, the head-
light washer system may be deprimed.
Fill the windscreen washer fluid and
then activate the windscreen washer,
with the engine running , to reprime
the system.
Before any action on the
windscreen (washing the
vehicle, de-icing, cleaning
the windscreen, etc.) return
stalk 1 to position A (park).
Risk of injury and/or damage.
Windscreen washer
With the ignition on , pull stalk 1 then
release.
A brief pull will trigger a single sweep
of the wipers, in addition to the wind-
screen washer.
A longer pull will trigger three sweeps
of the wipers followed, a few seconds
later, by a fourth, in addition to the wind-
screen washer.

SPECIAL FEATURES OF PETROL VERSIONS
The following operating conditions:
– driving for long periods when the low fuel level warning light is lit;
– using leaded petrol;
– using fuel or lubrication additives which are not approved.
Or operating faults such as:
– faulty ignition system, running out of fuel or disconnected spark plugs re-
sulting in the engine misfiring or cut-
ting out when driving;
– loss of power,
as they may cause the catalytic con-
verter to overheat and thus reduce its
efficiency, or damage it irreparably
and cause heat damage to the vehi-
cle. If you notice any of the above operating
faults, have the necessary repairs car-
ried out as soon as possible by an ap-
proved Dealer.
These faults may be avoided by regu-
larly taking your vehicle to an approved
Dealer at the intervals specified in the
Maintenance Service Booklet.
Starting problems
To avoid damaging the catalytic con-
verter,
do not keep trying to start the
engine (using the start button, or by
pushing or towing the vehicle) without
having identified and corrected the
starting fault.
If the fault cannot be identified, do not
keep trying to start the engine, but con-
tact an approved Dealer.
Do not park the vehicle or
run the engine in locations
where combustible sub-
stances or materials such
as grass or leaves can come into
contact with the hot exhaust system.

– free them from the windscreen or rear screen when they have not
been used for a long time.

– In frosty weather, make
sure that the wiper blades
are not stuck by ice (to
avoid the risk of the motor
overheating).
– Check the condition of the wiper
blades.
Replace the wiper blades as soon
as they begin to lose efficiency
(approximately once a year).
Whilst changing the blade, take care
not to drop the arm onto the window
after it has been removed as this
may break the window.

OPERATING FAULTS (4/6)
On the roadPOSSIBLE CAUSESWHAT TO DO
Steering becomes heavy. Assistance overheating. Consult an approved dealer.
The engine is overheating. The cool-
ant temperature indicator is in the
warning zone and warning light
® comes 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.
Coolant boiling in the coolant reser-
voir. Mechanical fault: damaged cylinder
head gasket. Stop the engine.
Contact an approved dealer.
Radiator:
If there is a significant lack of coolant, remember that it must never b\
e 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 prepared in the correct p\
roportions. Reminder: only products approved
by our Technical Department may be used for this purpose.
