Depending on the vehicle, this is com-  
posed of:  
– the AbS (anti-lock braking  
system);  
– the electronic stability program  
(E.S.P.) with understeer control  
and traction control (A.S.R.);  
– emergency brake assist with, de-  
pending on the vehicle, braking  
anticipation.

AbS (anti-lock braking  
system)  
Under heavy braking, the ABS prevents  
the wheels from locking, allowing the  
stopping distance to be managed and  
keeping control of the vehicle.

strument panel along with the mes-  
sages “Check ABS”, “Check braking  
system” and “Check ESP”: the ABS,  
E.S.P. and emergency brake assist  
are deactivated. braking safety is  
still guaranteed;  
Under these circumstances, the vehi-  
cle can be steered to avoid an obstacle  
whilst braking. In addition, this system  
can increase stopping distances, par-  
ticularly on roads with low surface grip  
(wet ground etc.).

lit on the instrument panel accom-  
panied by the message “Braking  
system fault”: this indicates a fault  
with the braking system.  
You will feel a pulsation through the  
brake pedal each time the system is  
activated. The ABS does not in any way  
improve the vehicle’s physical perform-  
ance relating to the road surface and  
roadholding. It is still essential to follow  
the rules of good driving practice (such  
as driving at a safe distance from the  
vehicle in front etc.).  
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.  
In both cases, consult an approved  
Dealer.  
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).  
Your braking systems  
are partially operational.

it is essential to stop immediately,  
as soon as traffic conditions allow.

Understeer control  
Operating faults  
Electronic stability program  
(E.S.P.) with understeer  
control and traction control  
(A.S.R.)  
This system optimises the action of  
the E.S.P. in the case of pronounced  
understeering (loss of front axle road  
holding).  
When the system detects an operating  
fault the message “Check ESP” and the  
indicator light © appears on the in-  
strument panel. In this case, the E.S.P.  
and A.S.R. are deactivated.  
Electronic stability program (E.S.P.)  
Traction control (A.S.R.)  
Consult an approved dealer.  
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.).  
This system helps to limit wheelspin of  
the drive wheels and to control the ve-  
hicle when pulling away accelerating or  
decelerating.  
Operating principle  
A sensor in the steering wheel detects  
the direction selected by the driver.  
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.  
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  
The system also adjusts the engine  
speed to the grip available under the  
wheels, independently of the pressure  
exerted on the accelerator pedal.

tional safety; it is recommended that  
you do not drive with the function disa-  
bled. Correct this as soon as possible  
by pressing switch 1 again.  
Operating faults  
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.  
When the system detects an operat-  
ing fault the message “Check brak-  
ing system” appears on the instrument  
panel along with the © warning  
light.

Emergency brake assist  
Consult an approved dealer.  
This system supplements the ABS  
and helps reduce vehicle stopping dis-  
tances.  
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.  
Disabling the A.S.R. function  
Operating principle  
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 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.  
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.  
ABS braking is maintained as long as  
the brake pedal is applied.  
The message “Traction control off” is  
displayed on the instrument panel to  
inform you.

DRIVER CORRECTION DEVICES/AIDS (4/4)  
Hill start assistance  
This function assists the driver when  
starting on hills. It prevents the vehicle  
from rolling backwards, depending on  
the slope, by automatically applying the  
brakes when the driver lifts his/her foot  
off the brake pedal to depress the ac-  
celerator pedal.  
The hill start assistance  
system cannot completely  
prevent the vehicle from  
rolling backwards in all sit-  
uations (extremely steep gradients,  
etc.).  
System operation  
In all cases, the driver may depress  
the brake pedal to prevent the vehi-  
cle from rolling backwards.  
It only operates when the gear lever is  
in a position other than neutral (other  
than N or P for automatic transmis-  
sions) and the vehicle is completely  
stationary (brake pedal depressed)  
The hill start assistance function  
should not be used for prolonged  
stops: use the brake pedal.  
The system holds the vehicle for ap-  
proximately 2 seconds. The brakes are  
then gradually released (the vehicle will  
move according to the slope).  
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.
