Height and reach adjustment
Pull lever 1 and move the steering
wheel to the required position.
Then, push the lever beyond the point
of resistance to lock the steering wheel.
Make sure that the steering wheel is
correctly locked.
For safety reasons, only
adjust the steering wheel
when the vehicle is station-
ary.
1
Never switch off the igni -
tion when travelling down -
hill, and avoid doing so in
normal driving (assistance
is not provided).
v ariable 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).
Never leave the steering wheel on
full lock when the vehicle is station-
ary.
Do not drive with a low battery
charge. The steering wheel may not
operate correctly.
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.
A noise may be heard when the
steering wheel is moved quickly.
This is normal.
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.

Indicates that the vehicle has a serious engine fault.
“Engine overheating ”
Indicates that the engine is overheating.
“power steering fault” or “Risk of steering locking ”Indicates a fault in the steering.

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.

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
–
If the
© warning light, together
with the message “ Check power
steering ”, is displayed on the instru-
ment panel: please contact an au -
thorised dealer.
– If the warning light
®, together
with the message “ Power steering
fault”, is displayed on the instrument
panel, this indicates a fault in the
system.

® requires you to stop
as soon as traffic conditions
allow. Contact an approved
Dealer.
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.:
deformation of an axle).
To avoid any risk of accident, have
your vehicle checked by an ap -
proved Dealer.
