Replacing wheels/tyres
This system requires specific equip -
ment (wheels, tyres, hubcaps, etc.).
Contact an approved dealer to fit new
tyres and to find out about accessories
compatible with the system and avail -
able from manufacturer ’s accessory
outlets: the use of any other accessory
could affect the correct operation of the
system or damage the system.
t yre repair products
Because the valves are specially de -
signed, only use products approved by
our Technical Department.
tyRe PReSSURe MoNItoR (3/3)
Each of the sensors incorporated in the valves 3 is dedicated to a single

aBS (anti-lock braking
system)
Under heavy braking, the ABS prevents
the wheels from locking, allowing the
stopping distance to be managed and
keeping control of the vehicle.
Under these circumstances, the vehi -
cle can be steered to avoid an obstacle
whilst braking. In addition, this system
can increase stopping distances, par -
ticularly on roads with low surface grip
(wet ground etc.).
You will feel a pulsation through the
brake pedal each time the system is
activated. The ABS does not in any way
improve the vehicle's physical perform-
ance relating to the road surface and
roadholding. It is still essential to follow
the rules of good driving practice (such
as driving at a safe distance from the
vehicle in front etc.).
Driver correction devices and aids
DRIVeR CoRReCtIoN DeVICeS aND aIDS (1/5)
Depending on the vehicle, they may
comprise:
– t h e aB S ( a n t i - l o c k b r a k i n g
system);
– eSC (electronic stability program)
with understeer control and a SR
traction control;
– emergency brake assist with, de -
pending on the vehicle, braking
anticipation;
– rear wheel steering.
In an emergency, apply firm and
continuous pressure to the brake
pedal. There is no need to pump
it repeatedly. The ABS will modu -
late the force applied in the braking
system.
These functions are an ad-
ditional aid in the event of
critical driving conditions,
enabling the vehicle behav -
iour to be adapted to suit the driving
conditions.
However, the functions do not take
the place of the driver. they do
not increase the vehicle’s limits
and should not encourage you
to drive more quickly. Therefore,
they can under no circumstances
replace the vigilance or responsibil -
ity of the driver when manoeuvring
the vehicle (the driver must always
be ready for sudden incidents which
may occur when driving).
Yo u r b r a k i n g s y s t e m s
are partially operational.
However, it is dangerous
to brake suddenly and
it is essential to stop immediately,
as soon as traffic conditions allow.
Contact an approved dealer.

electronic stability control
eSC with understeer control
and traction control aSR
electronic stability control eSC
This system helps you to keep control
of the vehicle in critical driving condi -
tions (avoiding an obstacle, loss of grip
on a bend, etc.).
operating principle
A sensor in the steering wheel detects
the direction selected by the driver.
Other sensors throughout the vehicle
measure the actual direction.
The system compares driver input to
the actual trajectory of the vehicle and
corrects the trajectory, if necessary, by
controlling the braking of certain wheels
and/or engine power. In the event that
the system is engaged, warning light
 flashes on the instrument panel. Understeer control
This system optimises the action of the
ESC in the case of pronounced under
-
steer (loss of front axle road holding).
t raction control (aSR)
This system helps to limit wheelspin of
the drive wheels and to control the ve-
hicle when pulling away accelerating or
decelerating.
operating principle
Using the wheel sensors, the system
measures and compares the speed of
the drive wheels at all times and slows
down their over-rotation. If a wheel is
starting to slip, the system brakes au -
tomatically until the drive supplied be -
comes compatible with the level of grip
under the wheel again.
The system also adjusts the engine
speed to the grip available under the
wheels, independently of the pressure
exerted on the accelerator pedal. operating faults
When the system detects an operat
-
ing fault the message “Check ESC” and
warning light
© appear on the in-
strument panel. In this case, the ESC
and ASR are deactivated.
Consult an approved dealer.

Disabling the aSR function
In some situations (driving on very wet
ground: snow, mud, etc. or driving with
snow chains fitted), the system may
reduce the engine output to limit wheel -
spin. If this is not required, it is possible
to deactivate the function by pressing
switch 1.
The message “ Traction control off ” is
displayed on the instrument panel to
inform you.
Traction control (ASR) offers additional
safety; it is recommended that you do
not drive with the function disabled.
Correct this as soon as possible by
pressing switch 1 again.
Note: The function is reactivated auto-
matically when the ignition is switched
on or when a speed of approximately
24 mph (40 km/h) is exceeded.
emergency brake assist
This system supplements the ABS
and helps reduce vehicle stopping dis-
tances.
operating principle
The system is for detecting an emer -
gency braking situation. In this case,
the braking assistance immediately de-
velops maximum power and may trig -
ger ABS regulation.
ABS braking is maintained as long as
the brake pedal is applied.

operating faults
When the system detects an operat -
ing fault the message “ Check brak-
ing system” appears on the instrument
panel along with the

Consult an approved dealer.
Braking anticipation
Depending on the vehicle, when you
rapidly release the accelerator, the
system anticipates the braking ma -
noeuvre in order to reduce stopping
distances.
Special cases
When using the cruise control:
– if you use the accelerator, when you
release it, the system may be trig -
gered;
– if you do not use the accelerator, the
system will not be triggered.

Rear wheel steering
On equipped vehicles, this system,
when the vehicle is being driven, steers
the rear wheels according to driving
conditions: at low speed this system
offers manoeuvrability, at higher speeds
it optimises stability.
When driving at low speeds, the rear
wheels steer in the opposite direction to
the front wheels (figure A ) to increase
the vehicle’s manoeuvrability. This is
used when driving in towns, on winding
roads, during parking manoeuvres, etc.
When driving at speeds above 40 mph
(60 km/h), the rear wheels steer in the
same direction as the front wheels
(figure B) to optimise the vehicle’s sta-
bility. This is useful when changing
lanes or when cornering etc. operating faults

Parking the vehicle
When the vehicle is stopped, move the
lever to position P while keeping your
foot on the brake pedal: the gearbox is
in neutral and the drive wheels are me-
chanically locked by the driveshaft.
a pply the handbrake or, depending
on the vehicle, ensure that the elec-
tronic parking brake is applied.
Special circumstances
– If the road contours and bends
do not allow you to stay in auto -
matic mode (e.g.: in the mountains),
we recommend that you change to
manual mode.
This will prevent the automatic gear-
box from changing gears repeatedly
when climbing, and permit engine
braking on long descents.
– In cold weather , to prevent the
engine from stalling, wait a few mo-
ments before shifting the selector
lever from position P or N and en -
gaging D or R.
– Vehicles not fitted with traction
control: on a slippery surface or
surface with a low level of adhe -
sion, change to manual mode and
select second gear before starting
the engine to avoid wheelspin when
starting.
Driving in manual mode
With the selector lever in position D,
move the lever to the left. Shifting the
lever repeatedly allows you to change
gears manually:
– To move down through the gears,
push the lever backwards;
– To move up through the gears, push
the lever forwards.
The gear selected is displayed on the
instrument panel.
Special cases
Under certain driving conditions (e.g.
engine protection, electronic stability
program (ESP) operational etc.: ESC),
the “automatic system” may change
gear automatically.
Likewise, to prevent incorrect manoeu -
vres, a gear change may be refused by
the automatic system: in this case the
gear display flashes for a few seconds
as a warning.
aUtoMatIC GeaRBox (2/3)
An impact to the underside
of the vehicle (e.g.: striking
a post, raised kerb or other
street furniture) may result
in damage to the vehicle (e.g.: de -
formation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
proved Dealer.
In very cold weather, the system
may prevent the gears from being
shifted in manual mode until the
gearbox reaches the right tempera-
ture.

Bodywork maintenance
BODyWORk MAIntenAnCe (1/2)
you should
Wash your car frequently, with the
engine off, with cleaning products rec-
ommended by the manufacturer (never
use abrasive products). Rinse thor -
oughly beforehand with a jet:
– spots of tree resin and industrial
grime;
– mud in the wheel arches and under -
neath the body which forms damp
patches;
– bird droppings , which cause a
chemical reaction with the paint that
rapidly discolours paintwork and
may even cause the paint to peel
off;
wash the vehicle immediately to
remove these marks since it is im -
possible to remove them by polish -
ing;
– salt, particularly in the wheel arches
and underneath the body after driv -
ing in areas where the roads have
been gritted.
Remove any plant matter (resin, leaves,
etc.) from the vehicle regularly.
What you should not doDo not degrease or clean mechani -
cal components (e.g. the engine com -
partment), underneath the body, parts
with hinges (e.g. inside the doors) and
painted plastic external fittings (e.g.
bumpers) using high-pressure clean -
ing equipment or by spraying on prod-
ucts not approved by our Technical
Department. Doing this could give rise
to corrosion or operational faults.
Wash the vehicle in bright sunlight or
freezing temperatures.
Do not scrape off mud or dirt without
pre-wetting.
Allow dirt to accumulate on the exterior.
Allow rust to form following minor im -
pacts.
Do not use solvents not approved by
our Technical Department to remove
stains as this could damage the paint-
work.
Do not drive in snow or muddy condi -
tions without washing the vehicle, par-
ticularly under the wheel arches and
body.
A well-maintained vehicle will last
longer. It is therefore recommended to
maintain the exterior of the vehicle reg-
ularly.
Your vehicle has been treated with very
effective anti-corrosion products. It is
nevertheless subject to various outside
influences.
Corrosive agents in the atmosphere
–
atmospheric pollution (built-up and
industrial areas),
– saline atmospheres (near the sea,
particularly in hot weather),
– seasonal and damp weather condi -
tions (e.g. road salt in winter, water
from road cleaners, etc.).
Minor impacts
Abrasive action
Dust and sand in the air, mud, road grit
thrown up by other vehicles, etc.
You should take a number of minor pre-
cautions in order to safeguard your ve-
hicle against such risks.
