ESP (Electronic Stability Programme) and ASR (Traction control)
These systems are associated with and complementary to the ABS. If
there is a discrepancy between the trajectory being taken by the vehicle
and that desired by the driver, the ESP system acts automatically on the
brake of one or more of the vehicle’s wheels as well as on the engine, in
order to bring the vehicle back onto the desired trajectory.
The ASR system optimises traction, so as to prevent the wheels from
skidding, by acting on the brakes of the driving wheels as well as on the
engine. It also improves the vehicle’s steering stability under acceleration.
System operational
These warning lamps light up for a few seconds when the
ignition is switched on, to signal that the ESP/ASR system
is operational.
The system will remain operational until the ignition is switched off again.
Functioning
When the ASR system is active, this warning lamp flashes.
When the ESP system is active, this warning lamp flashes
accompanied by a sound signal.
Functioning anomaly
If the system starts to malfunction, this warning lamp comes on.
Contact a CITROËN dealer to have the system checked.
SAFETY ADVICE
The ESP system offers you
increased safety in normal driving,
but it is not there to encourage the
driver to take extra risks or to drive
at excessive speeds.
The correct functioning of
this system is dependent on
compliance with the manufacturer’s
recommendations in terms of
wheels (both rims and tyres),
braking components, electronic
components, and CITROËN fitting
and repairing procedures.
After any collision, have this system
checked out by a CITROËN dealer.
