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The ESP/ASR systems are no longer active.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.

operate the manual priming
pump until some resistance is
felt.
- Operate the starter motor while depressing the accelerator pedal
slightly until the engine starts.

attempt, wait 15 seconds before trying again.

QUESTIONSANSWERSSOLUTIONS
The rec eption qualit y of the radio station being listened to gradually deteriorates.
The vehicle is too distant from the transmitter, or no transmitter is present in the geographical area you are passing th rough.
activate the RDs function to allow the system to chec k whether a more power ful transmitter is to be found in the geographical area.
The environment (hills, high buildings, tunnels, underground car parks, etc.) is blocking reception, even in RDs mode.This phenomenon is normal and does not imply anythi ng wrong with the radio.
The aerial is absent or has been damaged (for example after going through a car wash or in an underground car park).Have the aerial checked by a CITROËN dealer.
When the engine is not running, the radio stops after a few minutes.
When the engine is switched off, the working time fo r the radio depends on the batter y charge. The interruption is nor mal: the radio goes into economy mode, cutting off in order to save the vehicle’s batter y.
you have to star t the engine so as to increase the bat-ter y charge.

In order to protect the audio equipment in excessiv e ambient temperatures, the radio goes into an automatic thermic protection mode which results in a reduction in sound volume or stopping of the CD player.
switch off the audio system for a few minutes in order to allow the system to cool down.
Why is one not informed in real time of a hold-up on the route even though the option for guidance by “traffi c info” is activated ?
When you star t up, the system takes a few minutes to c apture the traf fi c information via RDS-TMC.Wait for the traf fi c information to be safely received (pictogrammes displayed on the map) and make sure that you use the major ar terial roads to have “inform ed” navigation.
Only the major ar terial roads (motor ways and some d ual car-riageways) are featured in RDS-TMC traf fi c information).
It may happen that a hold-up is not repor ted by the tr af fi c info provider.
Why is a diversion not suggested when I have selected traf fi c info ?
Do not confuse the “traf fi c info” guidance option which can sug-gest a diversion (the “diver t” button appears in the w indow) with the menus “Display of traf fi c messages” or “Reading of traf fi c messages” which af fect only the display without recalculating the itinerar y (no “diver t” button in the window).
To have “informed” navigation with the detour proposi-tion, it is essential to activate the guidance option with “traf fi c info”.
