Safety  
Trajectory control systems  
Emergency braking assistance Anti-slip regulation (ASR)  
and dynamic stability  
control (dSC)  
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.  
Activation  
These systems are activated automatically  
each time the vehicle is started.  
They come into operation in the event of a grip  
or trajectory problem.  
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 is indicated by flashing of this  
warning lamp in the instrument panel.  
When braking in an emergency, press  
firmly without releasing the pressure.  
Operating fault  
Illumination of this warning lamp in the  
instrument panel and the lamp in the  
button, accompanied by an audible  
signal and a message, this indicates a  
malfunction of these systems.  
Have it checked by a CITROËN dealer or a  
qualified workshop.  
The DSC/ASR systems offer

Reactivation  
exceptional 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 depends on observation of the  
manufacturer's recommendations on:  
In extremely severe conditions (deep snow,  
mud...), when it is not possible to move off, it  
may be useful to temporarily deactivate the  
systems, so that the wheels can spin freely and  
regain grip.  
These systems are reactivated automatically  
each time the ignition is switched back on  
or from 30 mph (50 km/h) except 1.6 litre  
(THP 150, THP 155 and THP 160) and  
RACING petrol engines.

After an impact, have these systems  
checked by a CITROËN dealer or a
