© and  appear
on the instrument panel. In this case,
the ESC and traction control system
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).

2.18
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. Operating faults
When the system detects an operating
fault the message “CHECK ABS” ap-
pears 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.

2.19
DRIVER 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.).“Soft ground” mode
Press the switch 1: warning light 
comes on the instrument panel accom-
panied by the 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 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.
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).
“Road” mode
Upon starting up the vehicle, the
“STANDARD HIGHWAY MODE” 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.

DRIVING CORRECTION DEVICES AND AIDS (5/5)
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
depress 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.

2.21
TYRE PRESSURE LOSS WARNING (1/3)
1
When fitted to the vehicle, this system
notifies the driver if one or more tyres
lose pressure.
Operating principle
Each wheel (except for the emergency
spare wheel) has a sensor in the infla-
tion valve which periodically measures
the tyre pressure while driving.
Warning light
 1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punc-
tured tyre, etc.).
This function is an addi-
tional driving aid.
However, the function does
not take the place of the
driver. It cannot, therefore, under
any circumstances replace the vig-
ilance or the responsibility of the
driver.
Check the tyre pressures, including
the emergency spare wheel, once a
month.
Resetting the standard level
for the tyre pressures
This should be done:
– when the standard tyre pressure needs to be changed to adapt to
usage conditions (empty, carrying a
load, motorway driving, etc.);
– after swapping a wheel (however this practice is not recommended);
– after changing a wheel.
It should always be done after checking
the tyre pressure of all four tyres when
cold.
Tyre pressures must correspond to the
current usage of the vehicle (empty,
carrying a load, motorway driving, etc.).

forms you of any tyre pressure faults
(flat tyre, punctured tyre, etc.).
“CHECK TYRE PRESSURES”
Warning light
 comes on, along
with the message “CHECK TYRE
PRESSURES”.
These indicate that at least one tyre is
flat.
Check and, if necessary, readjust the
pressures of the four wheels when cold.
The warning light
 goes off after a
few minutes’ driving.
“TYRE PUNCTURE”
The warning light
 comes on
steady, accompanied by the message
“TYRE PUNCTURE” and a beep.
This message appears along with the
® warning light.
They indicate that at least one wheel
is punctured or severely underinflated.
Replace it or contact an approved
dealer if it is punctured. Top up the tyre
pressure if the wheel is deflated.
Warning light ® re-
quires you to stop immedi-
ately, for your own safety,
as soon as traffic conditions
allow.
Resetting procedure
With the ignition on:
– repeatedly press button 3 or 4 to
select the “TYRE PRESSURE
ACQUISITION” function on the dis-
play 2;
– press and hold (around 3 sec- onds) button 3 or 4 to start initiali-
sation. Display of the message “TP
ACQUISTION LAUNCHED” indi-
cates that the reset request for the
tyre pressure reference value has
been taken into account.
Reinitialisation is carried out after a few
minutes’ driving.
The sudden loss of pressure in a
tyre (burst tyre, etc.) cannot be de-
tected by the system.

2.23
TYRE PRESSURE LOSS WARNING (3/3)
“CHECK TYRE SENSORS”
The warning light
 flashes for
several seconds, then stays on, along
with the message “CHECK TYRE
SENSORS”.
This message appears along with the
© warning light.
They indicate that at least one tyre is
not fitted with sensors (e.g. emergency
spare wheel). Otherwise, consult an
authorised dealer.
Readjustment of tyre
pressures
The tyre pressures must be adjusted
when cold (please refer to the label lo-
cated on the edge of the driver’s door).
If tyre pressures cannot be checked
when the tyres are cold, the recom-
mended pressures must be increased
by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.
Replacing wheels/tyres
This system requires specific equip-
ment (wheels, tyres, hubcaps, etc.).
Please see the information on “Tyres”
in Section 5.
Contact an approved Dealer to fit new
tyres and to find out about available ac-
cessories compatible with the system
and available from your dealer net-
work: the use of any other accessory
could affect the correct operation of the
system or damage a sensor.
Emergency spare wheel
If the vehicle is equipped with an emer- -
gency spare wheel, it will not have a
sensor. When it is fitted on the vehicle,
the warning light
 flashes for sev-
eral seconds, then stays on, together
with the warning light
© and the
message “CHECK TYRE SENSORS”
appears on the instrument panel.
Tyre repair product and
inflation kit
Because the valves are specially de-
signed, only use equipment approved
by the approved network. Please refer
to “Tyre inflation kit” in Section 5.
Changing a wheel
The system may take sev-
eral minutes depending on
use for the new wheel pres-
sures to be recognised; check the
tyre pressures after all operations.
