are deactivated.
Consult an approved dealer.
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.
DRIVING CORRECTION DEVICES AND AIDS (2/5)
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.
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.
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 vigi-
lance or responsibility of the driver
when manoeuvring the vehicle (the
driver must always be ready for
sudden incidents which may occur
when driving).

DRIVING CORRECTION DEVICES AND AIDS (3/5)
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. 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.
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.
Operating faults
When the system detects an operating
fault the message “CHECK BRAKING
SYSTEM” appears on the instrument
panel along with the
© warning
light.
Consult an approved dealer.
Driver assistance with a
trailer
This system helps to maintain control
over the vehicle while using a trailer.
It detects shaking caused by towing a
trailer under certain driving conditions.
Operating conditions
– The towbar must be approved by an authorised dealer;
– the harness must be approved by an authorised dealer;
– the towbar must be connected to the vehicle.
Operating principle
The function stabilises the vehicle by:
– asymmetric braking of the front wheels to reduce shaking caused by
the trailer;
– braking of all four wheels and limita- tion on engine torque to reduce the
vehicle speed until the shaking has
stopped.
Warning light
 flashes on the in-
strument panel to inform the driver.

Grip control
If fitted on the vehicle, grip control
makes it easier to control the vehicle on
low grip surfaces (soft ground, etc.).“Soft ground” mode
Press the switch 1: warning light 
comes on the instrument panel accom-
panied by the message “NON GRIP
ROAD MODE ON”.
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 about 31 mph
(50 km/h) and the
 warning light
on the instrument panel 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.

When the vehicle starts, the
“STANDARD ROAD MODE ON” mes-
sage is displayed on the instrument
panel. Warning light
 on the in-
strument panel is out.
This position enables optimal usage
under normal driving conditions (dry-
ness, humidity, light snow, etc.).
“Road” mode uses traction control func-
tions.

Switching off the function
The cruise control function is deacti-
vated if you press switch 1: in this case
a speed is no longer stored. The two in-
strument panel warning lights
 and
 go out to confirm that the function is
deactivated.
Returning to the cruising speed
If a speed is stored, it can be recalled,
once you are sure that the road con-
ditions are suitable (traffic, road sur-
face, weather conditions, etc.). Press
switch
4 (R) if the vehicle speed is
above 20 mph (30 km/h).
When the stored speed is recalled, acti-
vation of the cruise control is confirmed
by the illumination of the
 warning
light.
NB: if the speed previously stored is
much higher than the current speed,
the vehicle will accelerate more rapidly
to reach this threshold.
When the cruise control function is
put on standby, pressing switch 2
(+) reactivates the cruise control
function without taking into account
the stored speed: it is the speed at
which the vehicle is moving that is
taken into account.
Putting the function on
standby
The function is set to standby if you:
– use the switch 5 (O);
– the brake pedal;
– the clutch pedal;
In all three cases, the cruising speed
remains stored and the message
“MEMORISED” appears on the instru-
ment panel.
Standby is confirmed when indicator
light
 goes out.
CRUISE CONTROL (4/4)
Putting the cruise control
on standby or switching it
off does not cause a rapid
reduction in speed: you
must brake by depressing the brake
pedal.

VEHICLE WITH OVERSPEED FUNCTION
The vehicle speed may be permanently
set at a fixed value depending on the
vehicle or on local legislation.
To adjust the value or activate/deacti-
vate the function, consult an approved
dealer.
In the event of statutory limits (depend-
ing on the vehicle), this function may
not be deactivated.
Label 1 attached to the dashboard
shows the speed limit. Special case:
if your vehicle is fitted
with the Cruise control/Speed limiter,
fully depressing the accelerator pedal
(beyond the kickdown point) will not
allow you to exceed the overspeed
function set speed (refer to the informa-
tion on the “Speed limiter” in Section 2).
In exceptional circumstances (e.g.
steep gradient), the overspeed
function speed may be exceeded
slightly as the function does not
affect the braking system.
The function does not take
the place of the driver.
Under no circumstances
should it replace observa-
tion of speed limits nor vigilance
and responsibility on the part of the
driver.
