There are 7 possible adjustments.
Entry of air in automatic mode (activated by default, in automatic comfort regulation)
Automatic mode makes use of an air quality sensor. This analyses the air and isolates the passenger com-partment from the exterior as soon as it detects the presence of pollutants. Then it automatically activates recirculation of cabin air.

Closing of the air inlet
- Press on button 5 to close off the entry of air from outside.2
Whilst retaining the other adjustments, this position enables the driver at any time to exclude any disa-greeable odours or fumes coming from outside the vehicle.
It should be cancelled as soon as possible to permit renewal of cabin air and to prevent misting.
- Press once on button 5 to return to the initial status (entry of air in automatic mode).
Note : The airrecirculation can also be accessed by means of a press on the control located low down to one side of the steering wheel (see “Fixed centred controls steering wheel”).
Entry of air (manual mode)
- Press on button 5 to activate entry of air from the outside. The warning lamp goes out. 3

WHEEL FOR TEMPORARY USE
If your vehicle is equipped with a spare wheel for temporary use o n l y , w h e n fi t t i n g t h i s i t i s n o r m a l to observe that the wheel bolts do not come to bear directly on the wheel rim.
The spare wheel is secured by the conical tapering of the wheel bolt’s shaft (see illustration).
W h e n r e fi t t i n g t h e o r i g i n a l w h e e l , ensure that the wheel bolt contact surfaces are clean and in good condition.
WHEEL EQUIPPED WITH DEFLATION DETECTION SYSTEM
Such wheels have tyre pressure sensors. It is essential to have re-pairs carried out by a CITROËN dealer.
ANTI-THEFT BOLTS (alloy wheels)
Each wheel may be equipped with one anti-theft bolt.
To remove it :
1. Remove the protector that is covering it by means of the tool 2 (for removing the chrome covers on alloy wheels).
2. Use the anti-theft socket 9with the handle.
DIMENSION OF THE SPARE WHEEL
If your spare wheel has dimen-sions different from those of the n o r m a l v e h i c l e w h e e l s ( i d e n t i fi e d by a label), it is imperative to use the spare wheel only temporarily, to drive with caution, not to exceed 80 km/h (50 mph) and to have the tyre repaired and the normal wheel r e fi t t e d a s s o o n a s p o s s i b l e .
Tyre pressures
These are indicated on the label on the front left-hand door pillar ( s e e « V e h i c l e I d e n t i fi c a t i o n » ) .

REFITTING A WHEEL
1. Position the wheel with the aid of the centring guide 3.
2. Do up the 3 bolts by hand, then remove the centring guide 3. Position the 4th bolt.
3. Pre-tighten the wheel bolts, using the wheelbrace 4.
4. Retract the jack 5 and disen-gage it.
5. Tighten the wheel bolts, using the wheelbrace 4.
6. Ensure that the tyre pressure is correct (see “Vehicle identi- fi c a t i o n ” ) .

The system may be affected from time to time by interference from radio transmissions on similar frequencies.
This function alerts you in the e v e n t o f a t y r e b e i n g d e fl a t e d o r punctured. For this purpose, sen-sors continuously monitor the con-dition of the vehicle’s wheels.
This system does not absolve the driver of the need to check the tyre pressures regularly.

The wheel affected will no longer be detectable by the alert system if it is in the boot or undergoing re-pair. The spare wheel is not moni-tored by the alert system.
The SERVICE warning lamp comes on and a vehicle outline is dis-played, accompanied by a message and a sound signal. The wheel(s) concerned will be shown as ab-sent on the vehicle outline. If you have not changed a wheel, this in-formation indicates a malfunction-ing of the system.
Consult the CITROËN network to have the defective sensor(s) re-placed.
Wheel not monitored
T h e d e fl a t i o n d e t e c t i o n s y s t e m i s a driving assistance function which does not relieve the driver from the responsibility to be vigilant.
This system does not absolve the driver of the need to check the tyre pressures on a regular basis ( s e e “ V e h i c l e i d e n t i fi c a t i o n » ) , t o ensure that the vehicle behaves as it should and to avoid prema-ture wear on the tyres, especially when the vehicle is being subject-ed to heavy loads or driven at high speeds.
Do not forget to check the tyre pressure on the spare wheel.
