WHEEL FOR TEMPORARY USE
If your vehicle is equipped with a spare wheel for temporary use only, when fi tting this it is normal 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).
When refi tting the original wheel, 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 normal vehicle wheels (identifi ed 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 refi tted as soon as possible.
Tyre pressures
These are indicated on the label on the front left-hand door pillar (see "Vehicle Identifi cation").
The wheel bolts are specifi c to each type of wheel.
If new wheels are fi tted, check with your CITROËN dealer that the wheel bolts are compatible with the new wheels.

The system may be affected from time to time by interference from radio transmissions on similar frequencies.
This function alerts you in the event of a tyre being defl ated or 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 SERVICE warning lamp comes on and a ve-hicle outline is displayed, accompanied by a mes-sage and a sound signal. The wheel(s) concerned will be shown fl ashing on the vehicle outline. Check the tyre pressures as soon as possible.

Puncture
Change the damaged wheel (whether punctured or substan-tially defl ated), have the tyre re-paired as soon as possible, then check the tyre pressures as soon as you can after that.
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
The defl ation detection system is 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 (see “Vehicle identifi cation"), to 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.
