DRIVER CORRECTION DEVICES AND AIDS (2/3)
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.

Emergency brake assistThis 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.
Hazard warning lights switching on
Depending on the vehicle, these may
light up in the event of sudden decel-
eration.
Operating faultsWhen the system detects an operating
fault the message “BRAKING FAULT”
appears on the instrument panel along
with the
© warning light. Please
consult an authorised dealer.
DRIVER CORRECTION DEVICES AND AIDS (3/3)
Hill start assistance
Depending on the gradient of the in-
cline, this system assists the driver
when starting on a hill. It prevents the
vehicle from rolling backwards, de-
pending on the slope, by automatically
applying the brakes when the driver lifts
his/her foot off the brake pedal to de-
press the accelerator pedal.
System operation
It only operates when the gear lever is
in a position other than neutral and the
vehicle is completely stationary (brake
pedal depressed).
The system holds the vehicle for ap-
proximately 2 seconds. The brakes are
then gradually released (the vehicle will
move according to the slope).
The hill start assistance
system cannot completely
prevent the vehicle from
rolling backwards in all sit-
uations (extremely steep gradients,
etc.).
In all cases, the driver may depress
the brake pedal to prevent the ve-
hicle from rolling forwards or back-
wards.
The hill start assistance function
should not be used for prolonged
stops: use the brake pedal.
This function is not designed to im-
mobilise the vehicle permanently.
If necessary, use the brake pedal to
stop the vehicle.
The driver must remain particularly
vigilant when driving on slippery or
low-grip surfaces and/or on hills.
Risk of serious injury.

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 Speed limiter activation, memory and increase (+).
3 Decreasing the speed limiter (-).
4 Speed limiter function standby (with limited speed memory) (O).
5 Activation and recall of memorised limit 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 resistance point).
Whilst the speed is being exceeded,
the cruising speed displayed on the in-
strument panel flashes.
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
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 limit speed remains stored
and the message “SPEED MEMORY”
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 deacti-
vated when you press switch 1. In this
case, the speed is no longer stored.
The orange instrument panel warning
light
goes out, confirming that the
function is stopped.

and the cruise control function is active,
you may lift your foot off the accelera-
tor pedal.
Switching on
Press switch 1 side .
Indicator light 6 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.
Please note that you must
keep your feet close to the
pedals in order to react in
an emergency.
CRUISE CONTROL (2/4)

Activating cruise controlAt 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 a message on the
instrument panel and warning light 7 lit
green, as well as warning light 6.

CRUISE CONTROL (3/4)
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-
strument panel.
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.
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.

2.24
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 green
and indicator lights
on the instrument panel go out, con-
firming that the function is deactivated.
Recalling the cruising speed
If a speed has been stored, it can be re-
called by pressing button 5 (R), on con-
dition that you are driving faster than
approximately 20 mph (30 km/h) and
that you are sure that the driving condi-
tions are suitable (traffic, road surface
condition, weather conditions, etc.).
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:
– the brake pedal;
– move to neutral position;
– switch 4 (O).
In all three cases, the cruising speed is
stored.
Standby is confirmed when the green
warning light goes out and the
“stored” message appears on the in-
strument panel.
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.
