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.
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).
Operating faults
When the system detects an operat-
ing fault the message “Check ESC” and
warning light
© and appear
on the instrument panel. In this case,
the ESC and traction control system
are deactivated.
Consult an approved dealer.

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.). “Soft ground” mode uses trac-
tion control functions. The system au-
tomatically switches to “Road” mode at
speeds above 30 mph (50 km/h), and
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.

“Road” mode
Upon starting up the vehicle, 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 on
Press the side switch 1 . Indicator
light 6 comes on, lit orange, and the
message “SPEED LIMITER” appears
on the instrument panel, accompanied
by dashes to indicate that the speed
limiter function is activated and waiting
to store a limited 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 Activation and recall of memorised limit speed (R).
5 Speed limiter function standby (with limited speed memory) (O).
The speed limiter function helps you
stay within the driving speed limit that
you choose, known as the
limit speed.

Exceeding the limit speed
It is possible to exceed the limit speed
at any time. To do this: press the accel-
erator pedal firmly and fully (beyond
the resistance point).
If the speed is exceeded, the limited
speed flashes on the instrument panel
accompanied by a beep.
Then, release the accelerator: the
speed limiter function will return as
soon as you reach a speed lower than
the stored speed.
Limited speed cannot be maintained
If driving up or down a steep gradient,
the system is unable to maintain the
limited speed: the memorised speed
flashes on the instrument panel and
a beep sounds at regular intervals to
inform you.
Varying the limit speed
The limit speed may be changed by re-
peatedly pressing:
– switch 2 (+) to increase speed;
– switch 3 (-) to reduce speed.
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”).

Recalling the limit speed
If a speed has been saved, it can be re-
called by pressing switch 4 ((R)).
Putting the function on
standby
The speed limiter function is suspended
when you press switch 5 (O). In this
case, the limit speed remains stored
and the message “MEMORISED” ac-
companied by this speed appears on
the instrument panel.
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 warning light
goes out, confirming that the func-
tion is stopped.
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.

The cruise control function helps you to
maintain your driving speed at a speed
that you choose, called the cruising
speed.
This cruising speed may be set at any
speed above 20 mph (30 km/h).
This function is an addi-
tional driving aid. However,
the function does not take
the place of the driver.
Therefore, it can under no circum-
stances replace the driver’s respon-
sibility to respect speed limits and to
be vigilant (the driver must always
be ready to brake).
Cruise control must not be used in
heavy traffic, on undulating or slip-
pery roads (black ice, aquaplan-
ing, gravel) and during bad weather
(fog, rain, side winds etc.).
There is a risk of accidents.
The cruise control function
is in no way linked to the
braking system.
Controls
1 Main “On/Off” switch.
2 Cruising speed activation, storage and increase switch (+).
3 Decreasing cruising speed (-).
4 Activation with recall of saved cruis- ing speed (R).
5 Switch the function to standby (with cruising speed saved) (O).

Driving
Once a cruising speed is stored and
the cruise control function is active,
you may lift your foot off the accelera-
tor pedal.
Important: you are never-
theless advised to keep
your feet close to the pedals
in order to react if neces-
sary.
Activating cruise control
At a steady speed (above 18 mph
(30 km/h approximately)) press switch 2
or (+): the function is activated and the
current speed is saved.
The cruising speed replaces the dashes
and the cruise control is confirmed by
the appearance of warning light 6 lit
green, as well as warning light 7.
Switching on
Press switch 1 side .
Indicator light 7 comes on, lit green, and
the message “CRUISE CONTROL” ap-
pears on the instrument panel, accom-
panied by dashes to indicate that the
cruise control function is activated and
waiting to store a cruising speed.
