Trajectory control systems  
Emergency braking assistance  
Anti-slip regulation (ASR)  
and dynamic stability control  
(DSC)  
Intelligent traction control  
system ("Snow motion")  
System which, in an emergency, enables you  
to obtain the optimum braking pressure more  
quickly, thus reducing the stopping distance.  
The anti-slip regulation (also known as traction  
control) optimises traction to prevent skidding  
of the wheels, by acting on the brakes of the  
driving wheels and on the engine.  
The electronic stability control acts on the brake  
of one or more wheels and on the engine to  
keep the vehicle on the trajectory required by  
the driver, within the limits of the laws of physics.  
Depending on version, your vehicle has a  
system to help driving on snow: intelligent  
traction control.  
Activation  
It is triggered by the speed at which the brake  
pedal is pressed.  
The effect of this is a reduction in the  
resistance of the pedal and an increase in  
braking efficiency.  
This system detects situations of difficult  
surface grip that could make it difficult to move  
off or make progress on deep fresh snow or  
compacted snow.  
In these situations, the intelligent traction  
control limits the amount of wheel spin to  
provide the best traction and trajectory control  
for your vehicle.  
Activation  
These systems are activated automatically  
each time the vehicle is started.  
When braking in an emergency, press  
firmly without releasing the pressure.  
The use of snow tyres is strongly  
recommended on surfaces offering low  
levels of adhesion.  
They come into operation in the event of a grip  
or trajectory problem.  
This is indicated by flashing of this  
warning lamp in the instrument panel.

Deactivation  
Reactivation  
These systems are reactivated automatically  
each time the ignition is switched back on or  
from 30 mph (50 km/h).  
In extremely severe conditions (deep snow,  
mud, ...), if you are unable to move off, it may  
be useful to temporarily deactivate these  
systems so that the wheels can spin freely and  
allow the vehicle to move.  
The trajectory control systems offer  
increased safety in normal driving, but  
this should not encourage the driver to  
take extra risks or drive at high speed.  
The correct functioning of these  
systems is assured provided that  
manufacturer's recommendations are  
observed on:

The illumination of the indicator  
lamps in the instrument panel and  
in this button, accompanied by an  
audible signal and a message in the  
screen, indicates a fault with these  
systems.  
After an impact, have these systems  
checked by a CITROËN dealer or a  
qualified workshop.

Press this button, located near the steering  
wheel.  
If the indicator lamp in the button comes on, this  
indicates that these systems are deactivated.  
It is recommended that the systems be  
reactivated as soon as possible.
