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

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 to alert the driver in the event of insufficient pressure (deflated wheel, punctured tyre, etc.).

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.

Resetting the standard level for the tyre pressures

This should be done:

- 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 or right-hand wheel (note: 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 (please refer to the information on “Tyre pressure” in section 4).

To reset:

- briefly press button 4 or 5 to select the journey parameters and use button 2 to navigate to the “Tyre pressure SET [Press-hold]” function on the 3 display;

- press and hold (for around three seconds) button 24 or 5 to start initialisation. The message “Learning TP initiated” 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 value of the tyre pressure can not 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.

If the tyre pressure resetting conditions are not met, the message “Tyre pressure SET unavailable” will be displayed on the instrument panel.


The display 3 on the instrument panel informs you of any tyre pressure faults (flat tyre, punctured tyre, etc.).

“Adjust tyre pressure”

Warning light comes on, along with the message “Adjust tyre pressure”. 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.


The warning light comes on steady, accompanied by the message “Puncture” 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.

The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be detected by the system.

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 several seconds, then stays on, along with the message “Check tyre pressure sensors”.

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, increase the recommended pressures 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 your dealer network: using any other accessory could affect the correct operation of the system.

Emergency spare wheel

If the vehicle is equipped with an emer- gency 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.
