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.

hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel -
eration.
operating faults
When the system detects an operat -
ing fault the message “ Check brak-
ing system” appears on the instrument
panel along with the
© warning
light.
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

thorised dealer.
– If the warning light

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.

CRUISe CoNtRoL/SPeeD LIMIteR: speed limiter function (2/3)
Driving
When a limited speed has been stored
and this speed is not reached, driving is
similar to driving a vehicle without the
speed limiter function.
Once you have reached the stored
speed, no effort on the accelera -
tor pedal will allow you to exceed
the programmed speed except in an
emergency (refer to information on
“Exceeding the limit speed”).
Varying the limit speed
To vary the limit speed, press switch 2
(+) repeatedly to increase the speed or
switch 3 (-) to decrease it.
exceeding the limit speed
It is possible to exceed the limit speed
at any moment. To do this: press the
accelerator pedal firmly and fully
(beyond the kickdown point).
Whilst the speed is being exceeded,
the cruising speed displayed on the in-
strument panel flashes.
Then, release the accelerator pedal:
the speed limiter function will return as
soon as you reach a speed lower than
the stored speed. Limited speed cannot be maintained
When driving down a steep gradient,
the system is unable to maintain the
limit speed: the stored speed will flash
on the instrument panel information dis-
play to inform you of this situation.

The speed limiter function is
in no way linked to the brak-
ing system.

Putting the function on
standby
The speed limiter function is sus -
pended when you press switch 4 (O).
In this case, the limit speed remains
stored and the message "stored" ac -
companied by this speed appears on
the instrument panel.

Recalling the limit speed
If a speed has been stored, it can be re-
called by pressing switch 5 (R).
When the speed limiter is sus -
pended, pressing switches 2 (+)
or 3 (-) reactivates the function with-
out taking into account the stored
speed: it is the speed at which the
vehicle is moving that is taken into
account.
Switching off the function
The speed limiter function is deac -
tivated if you press switch 1 : in this
case a speed is no longer stored. The
orange
 instrument panel indicator
light goes out to confirm that the func-
tion is deactivated.

adjusting the cruising speed
The cruising speed may be changed by
pressing the following repeatedly:
– switch 2 (+) to increase the speed,
– switch 3 (-) to decrease the speed.
The cruise control function
is in no way linked to the
braking system.
exceeding the cruising speed
The cruising speed may be exceeded
at any time by depressing the accelera -
tor pedal. While it is being exceeded,
the cruising speed flashes on the in -

Then, release the accelerator: after a
few seconds, the vehicle will automati-
cally return to its set cruising speed.
Cruising speed cannot be
maintained
When driving down a steep gradient,
the system is unable to maintain the
cruising speed: the stored speed will
flash on the instrument panel informa -
tion display to inform you of this situ -
ation.
