DRIVING CORRECTION DEVICES AND AIDS (2/5)
Electronic stability program
ESC with understeer control
and traction control
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, indicator 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).
Traction control
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 operating
fault the message “CHECK ESC” and
warning light
© appear on the in-
strument panel. In this case, the ESC
and traction control system are deacti-
vated.
Consult an approved dealer.

Disabling the traction control
system
(depending on vehicle)
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.The traction control system offers ad-
ditional safety. It is recommended that
you do not drive with the function di-
sabled. Correct this as soon as pos-
sible by pressing the 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 is an additional system to ABS
which helps reduce vehicle stopping
distances.
Operating principle
The system detects an emergency
braking situation. In this case, the brak-
ing assistance immediately develops
maximum power and may trigger ABS
regulation.
ABS braking is maintained as long as
the brake pedal is not released.
DRIVING CORRECTION DEVICES AND AIDS (3/5)
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 operating
fault the message “BRAKING FAULT”
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.1

DRIVING CORRECTION DEVICES AND AIDS (4/5)
Grip control
If fitted on the vehicle, grip control
makes it easier to control the vehicle on
low grip surfaces (soft ground, etc.).
“Road” mode
Upon starting up the vehicle, the
“STANDARD HIGHWAY MODE” mes-
sage is displayed on the instrument
panel. The warning light on the switch 1
goes out.
This position enables optimal usage
under normal driving conditions (dry-
ness, humidity, light snow, etc.).
“Road” mode uses traction control func-
tions. “Soft ground” mode
Press the switch 1: the integrated war-
ning light
1 comes on, along with the
instrument panel message “VARIABLE
HIGHWAY MODE”.
This position enables optimal usage on
soft ground (mud, sand, dead leaves,
etc.). In this position, engine speed is left
under the driver’s control. The system
automatically switches to “Road” mode
at speeds above 30 mph (50 km/h), and
the warning light on button 1 goes out.
Tyres
When they need to be re-
placed, only tyres of the
same make, size, type and
profile should be used.
Tyres fitted to the vehicle should
either be identical to those fitted
originally or conform to those
recommended by your approved
dealer.

The speed limiter function helps you
stay within the driving speed limit that
you choose, known as the limit speed.
SPEED LIMITER (1/3)

Switching on
Press the side switch 1 . Warning
light
comes on, lit orange, and the
“SPEED LIMITER” message appears
on the instrument panel, accompanied
by dashes to indicate that the speed
limiter function is activated and waiting
to store a limit speed.
To store the current speed, press
switch 2 (+): The limit speed will replace
the dashes.
The minimum stored speed is 20 mph
(30 km/h).
Controls
1 Main “On/Off” switch.
2 Limit speed activation, storage and increase switch (+).
3 Decreasing the limit speed (-).
4 Speed limiter function standby (with limited speed memory) (O).
5 Activation and recall of memorised limited speed (R).

SPEED LIMITER (2/3)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.
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
The limit speed may be changed by re-
peatedly pressing:
– switch 2 (+) to increase the speed;
– switch 3 (-) to decrease the speed.

SPEED LIMITER (3/3)
Putting the function on
standby
The speed limiter function is suspended
when you press switch 4 (O). In this
case, the limited speed remains stored
and the “SPEED MEMORY” message
accompanied 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 put on
standby, pressing switch 2 (+) re-
activates the function without 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 interrupted
when you press switch 1. In this case,
the speed is no longer stored. The in-
strument panel orange indicator light
goes out to confirm that the func-
tion is deactivated.
