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, 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 the vehicle to
retain neutral behaviour on the road.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
