Driving safety
TRACTION CONTROL (ASR)
AND DYNAMIC STABILITY
CONTROL (ESP)
These systems are linked and
complement the ABS.
The ASR system is very useful for
maintaining optimum drive and
avoiding losses of control of the vehicle
on acceleration.
The 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.
Use the ESP to hold your course
without attempting to countersteer.
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. Disarming the ASR/ESP
systems
In certain exceptional conditions
(starting the vehicle when 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.
- Press the button, located on the
centre console.
- The indicator light comes on: the ASR and ESP systems no longer
act. Operating check
Good practice
The ASR/ESP systems offer increased
safety during normal driving, but
should not incite the driver to take risks
or to drive at high speed.
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 fi tting and repair
procedures within the CITROËN
network are observed.
After an impact, have these systems
checked by a CITROËN dealer.
Operation of the ASR and ESP
systems
The luminous diode fl ashes
when the ASR or ESP is
triggered.
They engage again:
- automatically above 30 mph (50 km/h),
- manually by pressing the button again. When a malfunction of the
systems occurs, the indicator
light comes on, accompanied
by an audible signal and a
message on the display.
Contact a CITROËN dealer to have the
system checked.
The warning light may also come on if
the tyres are under-infl ated. Check the
pressure of each tyre.
