Under heavy braking, the ABS prevents  
the wheels from locking, allowing the  
stopping distance to be managed and  
keeping control of the vehicle.  
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.).  
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 per-  
formance relating to the road surface  
and road-holding. 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.).

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).

Understeer control  
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.  
Electronic stability program  
ESC with understeer control  
and traction control  
This system optimises the action of the  
ESC in the case of pronounced unders-  
teering (loss of front axle road holding).  
Electronic stability program ESC  
Traction control  
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 faults  
This system helps to limit wheelspin of  
the drive wheels and to control the ve-  
hicle when pulling away accelerating or  
decelerating.  
When the system detects an operat-  
warning light © and

Operating principle  
on the instrument panel. In this case,  
the ESC and traction control system  
are deactivated.  
Operating principle  
A sensor in the steering wheel detects  
the direction selected by the driver.  
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.  
Consult an approved dealer.  
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 also adjusts the engine  
speed to the grip available under the

Emergency brake assist  
This system supplements the ABS  
and helps reduce vehicle stopping dis-  
tances.  
Hill start assistance  
The hill start assistance  
system cannot completely  
prevent the vehicle from  
rolling backwards in all sit-  
uations (extremely steep gradients  
etc.).  
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.  
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.  
In all cases, the driver may depress  
the brake pedal to prevent the vehi-  
cle from rolling backwards.  
System operation  
The hill start assistance function  
should not be used for prolonged  
stops: use the brake pedal.  
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).  
This function is not designed to im-  
mobilise the vehicle permanently.  
Hazard warning lights switching on  
Depending on the vehicle, these may  
light up in the event of sudden decel-  
eration.  
If necessary, use the brake pedal to  
stop the vehicle.  
The system holds the vehicle for ap-  
proximately 2 seconds. The brakes are  
then released (the vehicle will move ac-  
cording to the slope).  
The driver must remain particularly  
vigilant when driving on slippery or  
low-grip surfaces.  
Risk of serious injury.
