TYRE PRESSURE LOSS WARNING
When fitted to the vehicle, this system notifies the driver if one or more tyres lose pressure.
The system can be identified by the 1 label in the vehicle.
Operating principle
This system detects a loss of pressure in one of the tyres by measuring the wheel speed while driving.
In the event of insufficient tyre pressure (deflation, puncture etc.), the 2 warning light is continuously displayed to warn the driver.
Operating conditions
The system should be reset with a pressure equal to that stated on the tyre pressure label (refer to the information on “Tyre Pressures” in section 4), otherwise it may not give a reliable warning in the event of significant pressure loss.
Resetting should always be carried out after checking the tyre pressure of all four tyres when cold.
In the following situations, the system risk coming into action late or not functioning correctly:
- system not reset after reinflation or any operation on the wheels;
- system badly reset: different inflation pressures from the recommended pressures;
- significant change in load or distribution of load on one side of the vehicle;
- sporty driving with strong acceleration;
- driving on snowy or slippery surface;
- driving with snow chains;
- fitting a single new tyre;
- use of tyres not approved by the network.
Resetting the standard level for the tyre pressures
This should be done:
- after each re-inflation or resetting of tyre pressure;
- after changing a wheel;
- after changing wheels around.
Tyre pressures must correspond to the current usage of the vehicle (empty, carrying a load, motorway driving, etc.).
To reset the tyre pressure reference value, please see the following page.
This function is an additional driving aid.
The function does not take the place of the driver. It cannot, therefore, under any circumstances replace the vigilance or the responsibility of the driver. Check the tyre pressures, including the emergency spare wheel, once a month.
The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be detected by the system.
Resetting procedure via the multimedia screen 3
The resetting procedure must be carried out while the vehicle is stationary and the ignition is switched on. Please refer to the multimedia instructions for further information.
For your safety, the warning light ® requires you to stop immediately as soon as traffic conditions allow.
Readjustment of tyre pressures
The pressure of the four tyres must be set when cold (refer to the label located on the edge of the driver’s door).
If tyre pressures cannot be checked when the tyres are cold, the recommended pressures should be increased by 0.2 to 0.3 bar (3 PSI).
Never deflate a hot tyre.
After each reinflation or readjustment of the tyre pressure, launch the reinitialisation of the tyre pressure reference value.
Replacing wheels/tyres
Only use equipment approved by the Network, otherwise the system may be activated with a delay or operate incorrectly. TYRES.
After each change of wheel/tyre, readjust the tyre pressure and launch the reset of the tyre pressure reference value.
Emergency spare wheel
If fitted on the vehicle, readjust the tyre pressure and launch the reinitialisation of the tyre pressure reference value.
Tyre repair product and inflation kit
Only use equipment approved by the Network, otherwise the system may be activated with a delay or operate incorrectly. TYRE INFLATION KIT. After using the tyre inflation kit, readjust the tyre pressure and launch the resetting of the tyre pressure reference value.
Tyre pressure faults
The table on the following page lists the warning messages which appear on the instrument panel 4 when the system detects a tyre pressure fault.
The information on the instrument panel signals any potential tyre pressure faults (e.g. deflated or punctured tyre).
Indicator lights | Messages | Readings |
|---|---|---|
| Inflate tyres and init. | This indicates that tyre under-inflation or puncture has been detected. Check and adjust the pressure of the four tyres when cold and reset the system. |
+ © | Check TPW | This indicates a fault in the system. Consult an approved dealer. |
| TPW not available | This indicates that an emergency spare wheel different in size to the other four wheels has been fitted to the vehicle. The system remains unavailable until a wheel identical in size to the other wheels has been fitted and the resetting procedure has been carried out. |
