Tyre pressure loss warning

Operating principle

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.
The warning light 2 stays on to warn the driver in the event of insufficient tyre pressure (deflated, punctured tyre, etc.).
WARNING
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.

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" TYRE PRESSURE), 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;
  • incorrectly reset system: tyre pressures different 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.
Tip
Tyre pressure must be checked before starting the resetting procedure.
The system will not issue a warning if the pressure does not correspond to the recommended pressure.
Tip
The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be immediately detected by the system.

Procedure for resetting the standard levels for the tyre pressures

This should be performed:
  • 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.). Respect the tyre pressures (including the emergency spare wheel). Check them at least once a month and before a long journey (refer to the label on the edge of the driver’s door) TYRES.

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.

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) TYRE PRESSURE.
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 resetting of the tyre pressure reference value.

Replacing wheels/tyres

Only use equipment approved by the brand network, otherwise there is risk of the system being activated late or not working correctly TYRES.
After each change of wheel/tyre, readjust the tyre pressure and launch the reset of the tyre pressure reference value.

Tyre repair product and inflation kit

Only use equipment approved by the brand network, otherwise there is risk of the system being activated late or not working correctly 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 lists the warning messages that appear on the instrument panel 4 if 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).

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.
