lever with a force that is proportionate to the steepness of the slope.
To facilitate the action on the lever, you are recommended t o press the
brake pedal at the same time.
In all circumstances, as a precautionary measure, engage first gear. F or
vehicles equipped with an automatic gearbox, ensure that the parking
position ( P) is selected.

72 SAFETY RECOMMENDATIONS
The Esp system offers increased
driving safety but is not in place to
encourage the driver to take addi-
tional risks or to drive at excessive
speeds.
The functioning of this system is
subject to compliance with the
manufacturer’s recommendations
on wheels (tyres and rims), brake
parts and electronic components,
as well as with CITROËN’s assem-
bly and repair procedures.
after any collision, have this
system checked by a CITROËN
dealer.
Electronic Stability Programme (ESP) and Traction Control (ASR)
These systems are closely connected to the aBs and additional to i
t. In
the event of a loss of control of the vehicle by the driver, the ESP system
acts automatically on one or more brakes and also on the engine to bring
the vehicle back on trajectory. The ASR system optimises traction and
prevents wheel spin by acting on the brakes of the driving whe els. It also
improves steering stability during acceleration.
Operation
When either the Esp or asR system is brought into operation,
the ESP/ASR warning lamp flashes.
Deactivation
In exceptional conditions (vehicle stuck in snow, soft ground, e tc.) it may
prove useful to deactivate the Esp/asR system to allow the wheels to spin
and thus regain traction.
- press on control A, the ESP/ASR warning lamp and the control light up.
The ESP/ASR systems are no longer active.
The Esp/asR systems will activate again:
- Automatically after the ignition has been switched off.
- Automatically when you drive at above approx. 30 mph
(except 2.0i 16V 180hp engine).
- Manually with another press on control
A.
Operational anomaly
If there is a system malfunction, the ESP/ASR warning lamp comes on.
Contact CITROËN to have the system checked.
