Safety -> Trajectory control systems for Your Citroen C5 Suv Second Generation (2008-2017)

Safety  
Trajectory control systems  
Anti-slip regulation (ASR) and dynamic stability  
control (DSC)  
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  
difficult on deep fresh snow or compacted  
by the driver, within the limits of the laws of  
Intelligent traction control  
Activation  
system ("Snow motion")  
Your vehicle has a system to improve traction  
on snow: intelligent traction control.  
This system detects situations of low adhesion  
that might make moving off and progress  
These systems are activated automatically  
each time the vehicle is started.  
They come into operation in the event of a grip  
or trajectory problem.

physics.  
This is indicated by flashing of this  
warning lamp in the instrument panel.  
In these situations the intelligent traction  
control system regulates the amount of wheel  
slip to optimise the traction and trajectory  
control of your vehicle.  
For vehicles with Hydractive III + suspension,  
manual adjustment of ground clearance to  
the intermediate position improves further the  
ability to make progress in deep snow (see the  
relevant paragraph).  
The use of snow tyres is strongly  
recommended on surfaces with low  
adhesion.

Safety  
Deactivation  
Reactivation  
In exceptional conditions (starting a vehicle  
which is bogged down, stuck in snow, on soft  
ground...), it may be advisable to deactivate  
the DSC and ASR, so that the wheels can turn  
freely and regain grip.  
Reactivate the systems as soon as the level of  
grip permits.  
The systems are reactivated automatically  
each time the ignition is switched back on or  
from 30 mph (50 km/h).  
Below 30 mph (50 km/h), you can reactivate  
them manually:  
F
Press this button.  
The indicator lamp in the button  
comes on.  
F
Press this button again.  
The indicator lamp in the button  
goes off.  
The DSC and ASR systems no longer act  
on the operation of the engine and on the  
brakes in the event of a involuntary change of  
trajectory.

Operating fault  
Illumination of this warning lamp and  
the lamp in the deactivation button,  
accompanied by an audible signal  
and a message, indicate a fault with  
the system.  
Contact a CITROËN dealer or a qualified  
workshop to have the system checked.

Safety  
After an impact, have these systems  
checked by a CITROËN dealer or a  
qualified workshop.  
DSC/ASR  
The DSC and ASR systems offer increased safety in normal driving, but they should not  
encourage the driver to take extra risks or drive at high speed.  
It is in conditions of reduced grip (rain, snow, black ice) that the risk of loss of grip  
increases. It is therefore important for your safety to keep the DSC and ASR systems  
activated in all conditions, and particularly in difficult conditions.  
The correct operation of these systems depends on observation of the manufacturer's  
recommendations regarding as much the wheels (tyres and rims), braking and electronic  
components as the assembly and repair procedures used by CITROËN dealers.  
To benefit in full from the effectiveness of the DSC and ASR systems in wintry conditions,  
the vehicle must be fitted with four snow tyres, allowing the vehicle to retain neutral  
handling on the road.
