Tyre pressure monitoring system

When fitted to the vehicle, this system notifies the driver if one or more tyres lose pressure.
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 principle

Each wheel (except for the emergency spare wheel if fitted) has a sensor in the inflation valve which periodically measures the tyre pressure during driving.
Warning light 1 comes on steady to alert the driver in the event of insufficient pressure (deflated wheel, punctured tyre, etc.).

Resetting the standard level for the tyre pressures

This should be performed:
  • when the standard tyre pressure needs to be changed to adapt to usage conditions (empty, carrying a load, motorway driving, etc.);
  • after swapping a left-hand/right-hand wheel (this practice is not recommended);
  • after changing a wheel.
It should always be done after checking the tyre pressure of all four tyres when cold.
Tyre pressures must correspond to the current usage of the vehicle (empty, carrying a load, motorway driving, etc.).
Resetting procedure
Conditions for launching the reset:
  • ignition on;
  • vehicle stationary;
  • tyre pressure above 1.6 bar (refer to the information on "Tyre pressure" in Section 4).
Tip
If the tyre pressure resetting conditions are not met, the "Tyre pressure SET unavailable" message will be displayed on the instrument panel.
To reset:
  • press button 4 or 5 to select the trip parameters, then use the button 2 to browse to the "Tyre pressure: SET (press and hold)" function on the display 3;
  • press and hold (for around three seconds) on button 2, 4 or 5 to start resetting. The "Learning Tyre Pressures" message is displayed for approximately five seconds. The request to reset the reference tyre pressure value has been taken into account.
Reinitialisation is carried out after a few minutes' driving.
Note: the tyre pressure value cannot be less than that recommended and indicated on the edge of the driver's door or, depending on the vehicle, on the bottom of the driver's door.

Display

The 3 symbol appears on the instrument panel in the event of any tyre pressure faults (flat tyre, punctured tyre, etc.).
« Adjust Tyre Pressure »
The warning light appears and stays on, accompanied by the "Adjust Tyre Pressure" message. This indicates that at least one tyre is flat.
Check and, if necessary, readjust the pressures of the four wheels when cold. The warning light goes off after a few minutes' driving.
« Puncture »
The warning light appears and stays on, accompanied by the "Puncture" message and a beep.
This message appears along with the warning light.
They indicate that at least one wheel is punctured or severely underinflated. Replace it or contact an approved dealer if it is punctured. Top up the tyre pressure if the wheel is deflated.
Tip
The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be detected by the system.
WARNING
For your own safety, the warning light requires you to stop immediately, as soon as traffic conditions allow.
« Check Tyre Pressure Sensors »
The warning light flashes for a few seconds, then appears and stays on, accompanied by the "Check Tyre Pressure Sensors" message.
This message appears along with the warning light.
They indicate that at least one tyre is not fitted with sensors (e.g. emergency spare wheel). In other cases, contact an authorised dealer.

Readjustment of tyre pressures

The pressures must be adjusted when cold (refer to the label on the edge of the driver's door or, depending on the vehicle, on the bottom of the driver's door).
If the pressure 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.

Replacing wheels/tyres

This system requires specific equipment (wheels, tyres, etc.). Please see the information on "Tyres" in Section 5.
Contact an approved dealer to replace the tyres and to find out about accessories compatible with the system that are available from the brand's Network: using any other accessory could affect the correct operation of the system.

Emergency spare wheel

If the vehicle is equipped with an emergency spare wheel, it will not have a sensor.

Tyre repair product and inflation kit

Because the valves are specially designed, only use equipment approved by the approved network. Please refer to "Tyre inflation kit" in Section 5.
