ELECTRONIC STABILITY PROGRAMME
TheESP system offers increased
driving safety but is not in place toencourage the driver to take addi-
tional risks or to drive at excessivespeeds.
The operation of this s
ystem is
assured provided that the manufac-
turer’s recommendations concern-
ing the wheels (tyres and rims),
braking components and electricalcomponents are observed, as wellas the fi tting and repair proceduresused by CITROËN dealers andgpp
qualifi ed workshops.
Following an accident, have thesystem checked by a CITROËNg,
dealer or a qualifi ed workshop.
ELECTRONIC STABILITY PROGRAMME (ESP) AND TRACTION CONTROL (ASR)
These systems are closely associated with ABS and additional to it. In the event of a loss of control of the vehicle by the driver, theESPsystem acts
automatically on one or more wheels and also on the engine to bring the
vehicle back on trajectory. The ASRsystem optimises traction and prevents
wheel spin by acting on the brakes of the driving wheels as well as on the engine. It also improves steering stability during acceleration.
OPERATION
When either the ESPor the ASR system is brought into operation
the warning lamp "ESP/ASR" fl ashes.
DEACTIVATION
In exceptional conditions (vehicle stuck in snow, soft ground, etc.) it mayprove useful to deactivate theESP/ASR systems to allow the wheels tospin and thus regain traction.
Press on buttonA, the"ESP/ASR" warning lamp, as well as the lamp on
the buttonA, light up. TheESP/ASR systems are no longer active.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 (50 km/h).
Manuallywith another press on button A.
OPERATIONAL ANOMALY

AUTOMATIC AIR CONDITIONING
AIR CONDITIONING
This system automatically adjusts the temperature, the fl ow of air and the distribution of air inside the cabin,
depending on your desired comfort level.
Provided
you retain automatic mode (by pressing button "AUTO") and all the air vents are open, you will main-
tain an optimum comfort level, also removing humidity
and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than
the temperature outside if the air conditioning is not
operating.
To be e
ffective, the air conditioning should only be used
with the windows closed. If after a lengthy stop in bright sunlight the interior temperature is excessive, air the passenger compartment by opening the windows for a
few moments, then close them again.
To keep the air conditioning compressor well sealed, it
is essential to operate the air conditioning at least once every month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
Sensors
The automatic regulation of the air conditioning inside
the cabin makes use of a number of sensors, relieving you of the need to make adjustments, other than the desired cabin temperature.
Take care not to obstruct sensor A.
Air inlet
Check that the exterior grille for the air inlet, at the bot-
tom of the windscreen, is clean and free of dead leaves,snow, etc.
If washing the vehicle with a high pressure jet, avoid
targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper
distribution of air within the cabin, both at the front andat the rear.
The air vents to the
face have thumbwheels so that you can
adjust the fl ow of air, and grilles to orient the direction.
Th
ere are air vents on the fl oor underneath the frontseats and on the rear control panel, for enhancedheating of the rear seat positions.
Do not obstruct the air outlets located in the boot area.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This
fi lter has to be changed according to the vehicle
maintenance schedule. See "Maintenance and WarrantyGuide".

into direct contact with each other.
Check that the assisting battery has suffi cient voltage (12 V).
Connect the cables according to the orderindicated in rthe diagram.

Check that the leads are well secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine
run for around 1 minute at a slightly accelerated idle.
Operate the starter on the vehicle being assisted.
