These systems are linked and

Operating check
The ASR system optimises drive to
prevent the wheels skidding, by acting
on the brakes of the drive wheels
and on the engine. It also allows the
directional stability of the vehicle to be
improved on acceleration.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course, within the limits of the laws
of physics.
When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Consult a CITROËN dealer to have the
system checked.
Disarming the ASR/ESP
systems
In certain conditions (vehicle stuck in
mud or snow, or on loose ground...), it
could prove useful to disarm the ASR
and ESP systems to make the wheels
spin and regain grip.
The ASR/ESP systems offer
increased safety during normal
driving, but should not incite the

Activation of the ASR and ESP
systems
When the ignition is on, the ASR and
ESP systems are always active.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the fitting and repair
procedures within the CITROËN
network are observed.
