When the ignition is switched on, the oil level indicator is displayed for several seconds.This display indicates normal oper-ating.
A fl ashing of "OIL" indicates an oil level that is below the minimum.
Check using the manual dipstick.
Check the oil level with the vehicle on horizontal ground, the engine having been switched off for at least 15 minutes.
A fl ashing of "OIL --" indicates a malfunction of the indicator.
Consult your CITROËN dealer.

Air conditioning
At any time of year, the air condition-
ing is useful for removing air humid-
ity and misting.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
To be effective, the air conditioning
should only be used with the win-
dows closed.
If you are towing a heavy trailer or if
outside temperatures are very high,
the air conditioning may be tempo-
rarily interrupted in favour of engine
cooling.
Sensor
The automatic air conditioning inside the passenger compartment makes use of the sunlight sensor, which is located on the dashboard behind the instrument panel.
Take care not to obstruct it.
Water arising from condensation
in the air conditioning is allowed to
drain out through an aperture pro-
vided for this purpose; a pool of
water may thus form beneath the
vehicle when stationary.
You are recommended to have the
air conditioning system checked on
a regular basis (see Maintenance
Guide).
The air conditioning uses energy
from the engine to operate. This
results in extra fuel consumption

Manual gearbox
- Ensure that the gear lever is in the neutral position.
- Do not touch the accelerator.
- In the case of diesel engine vehi-cles: turn the key to the drive position. Wait for the pre-heater warning lamp to go off, if it is on.
- Action the starter by turning the key until the engine starts (but not for more than ten seconds).
- In temperatures lower than 0 °C, apply the clutch during the action on the starter in order to aid starting. Then release the clutch slowly.
DO NOT RUN THE ENGINE IN A SPACE THAT IS ENCLOSED OR INSUFFICIENTLY VENTILATED.
Automatic gearbox
- Check that you are in position P or N.
- Do not touch the accelerator.
- For Diesel engines: turn the key to position M. Wait for the pre-heater warning lamp to go off if it is on.
- Action the starter by turning the key until the engine turns over (not for longer than ten seconds).
Advice
Vehicles equipped with a Turbo:
Turbo equipped engines MUST be allowed to return to idle for several seconds before switching off the ignition. Failure to do so could cause serious damage to the turbo unit.
Flicking the throttle pedal as the ignition is turned off can lead to severe dam-age to the turbo unit.
(6 speed) Electronic Gearbox System
- Check that you are in position N.
- Fully depress the brake pedal.
- Do not touch the accelerator.
- For Diesel engines: turn the key to position M. Wait for the pre-heater warning lamp to go off if it is on.
- Action the starter by turning the key until the engine turns over (not for longer than ten seconds).
Note: If the vehicle has been sta-tionary for a long time, or if you have pressed the brake pedal a number of times while stationary, it will be necessary to press the brake pedal hard down in order to authorise the engine to start.

Neutral
If the vehicle is moving, do not select this position, even momentarily.
Reverse gear
Only engage reverse gear when the vehicle is stationary.
If the vehicle is moving at a very low speed, if reverse gear is requested (position R) this will be taken into account only when the vehicle comes to a halt.
The "foot on brake" warning lamp may fl ash in the instrument panel to remind you to brake.
If the vehicle is moving at a high speed, if reverse gear is requested the warning lamp "N" will fl ash and your vehicle will go automatically into neutral. To re-engage a gear, you have only to return the gear lever to position A or M.
A sound signal indicates when reverse gear is engaged.
If parking assistance is deacti-vated, the sound signal for reverse gear engaged is absent.
The engine can only be started if the brake pedal is pressed and the gear lever is in position N.
The warning lamp "foot on brake" fl ashes on the display.
With the engine running, before accelerating away check the position engaged by looking at the lever grille or the rev counter : R, A or M.
If you are stationary with the engine running, take care to leave your gear selector in position N.

Starting the vehicle
- To start the engine, the gear lever has to be in position N.
- Fully depress the brake pedal.
- Action the starter.
- With the engine running, depend-ing on your preference place the lever on R, A or M.
- Check the position engaged on the rev counter.
- Release the handbrake.
- Release the brake pedal and accelerate.
If the lever is not in position N, the warning lamp "N" fl ashes on the rev counter.
If the brake pedal is not pressed down, the warning lamp "Foot on brake" fl ashes in the instrument panel.
In both cases, the engine does not start; recommence the above proce-dure.
Note: If the vehicle has been sta-tionary for a long time, or if you have pressed the brake pedal a number of times while stationary, it will be necessary to press the brake pedal hard down in order to authorise the engine to start.
Stopping the engine
Before switching the engine off, you can choose:
- to leave the vehicle in neutral; for that, place the lever in position N,
- to leave the vehicle with a gear engaged (R, A or M); for that, place the lever in the position cho-sen. In this case, the vehicle can-not be moved.
In all cases, it is essential to apply the handbrake.
Before undertaking any operation in the engine compartment, make absolutely sure that the gearbox is in neutral and that the handbrake is on.
Do not hold the vehicle stationary using only the accelerator.
If you are stopped on an incline, use the handbrake to hold the vehicle.
Acceleration
To obtain optimum acceleration (for example to overtake another vehi-cle), you have only to press the pedal hard down to go beyond the end-of-travel switch.
