TYRE PRESSURE MONITOR
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 comes on on the dashboard to alert the driver in the event of insufficient pressure (tyre deflated, punctured etc.).
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.
The sudden loss of pressure in a tyre (burst tyre, etc.) cannot be detected by the system.
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.).
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 procedure
Ignition on, vehicle stopped:
- depending on the vehicle, press briefly on the 6 switch as many times as necessary to position in the area 7;
- briefly press the 3 or 4 switch to reach the “Tyre pressure init. long press” page;
- press and hold the 5 OK switch to launch the reset.
Hold down the 5 switch until the “Operation completed” message appears. You can now drive.
The table below shows the possible messages related to the tyre resetting procedure.
Steps | Messages | Readings |
|---|---|---|
- | Tyre pressure init. at stop | The message is displayed during driving. If you want to reset the pressure of the four tyres, stop the vehicle. |
1 | Tyre pressure init. long press | To reset the pressure of the four tyres, with the vehicle stopped, press and hold the 5 OK switch to launch resetting until the “If pressure OK [hold on]” message is displayed. |
2 | If pressure OK [hold on] | The message flashes to indicate that the system has registered the resetting procedure. If the pressure of the four tyres has been correctly set to the values recommended on the tyre pressure label (see Tyre pressure” in section 4), press and hold the 5 OK switch until the “Operation completed” message appears. |
3 | Operation completed | The resetting procedure has been completed successfully. You can now drive. |
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 brand network, or the system risks being activated late or not operating correctly. Please see the information on “Tyres” in Section 5.
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 brand network, or the system risks being activated late or not operating correctly. Please refer to “Tyre inflation kit” in Section 5.
After using the tyre inflation kit, readjust the tyre pressure and launch the reinitialisation 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 8 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 tyre press and init. | This indicates that the reset has been unsuccessful. Check and readjust the tyre pressure before re-launching the resetting procedure. |
Check tyre press and init. | This indicates that the last system reset was carried out over 6 months ago or over approximately 6,214 miles (10,000 km). Check and readjust the tyre pressure before re-launching another resetting procedure. | |
+ © | 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. |
If the vehicle is equipped with the function, this system monitors the tyre pressure.
Operating principle
Each wheel (except for the emergency spare wheel) has a sensor in the inflation valve which periodically measures the tyre pressure.
The system displays the current pressures on the instrument panel 1 and alerts the driver in the event of insufficient pressure.
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 wheel (however 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.).
If the vehicle is equipped with a navigation system, the resetting procedure may also be carried out using the multimedia screen: please see the equipment instructions.
Resetting procedure
Ignition on, vehicle stopped:
briefly press the 5 switch until you reach the 6 instrument panel 1 area;
- briefly press the 2 or 3 switch to reach the “Tyre Pressure” page;
- press and hold (around 3 seconds) the button 4 to launch the reset. The flashing tyres followed by the messages “Learning Tyre Pressures” and then “Tyres location in progress” indicates that the reset request for the tyre pressure reference value has been acknowledged.
Reset can take several minutes of driving.
If the resetting is followed by short trips, the message “Tyres location in progress” can remain displayed after successive restarts.
Note: the standard tyre pressure cannot be less than that recommended and indicated on the door frame.
For your safety, the warning light ® requires you to stop immediately as soon as traffic conditions allow.
The table below shows the possible messages related to the tyre resetting procedure.

3 |
| Tyres location in progress | The “---” quote marks in front of each wheel will remain lit. This system resets the tyre pressure of all four tyres. You can now drive. The message may remain displayed during short journeys. Note: during the reset, tyre pressure monitoring remains in operation. |
4 |
| The pressure value of the four tyres is displayed: the resetting procedure is complete and successful. |
Readjustment of tyre pressures
The tyre pressures should be adjusted when cold (please refer to the label located on the edge of the driver’s door). If the 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.
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.
Replacing wheels/tyres
This system requires specific equipment (wheels, tyres, hubcaps, etc.). Please see the information on “Tyres” in Section 5.
Contact an approved Dealer to fit new tyres and to find out about available accessories compatible with the system and available from your dealer network: the use of any other accessory could affect the correct operation of the system or damage a sensor.
Emergency spare wheel
If the vehicle is equipped with an emergency spare wheel, it will not have a sensor.
Changing a wheel
The system may take several minutes depending on use for the new wheel positions and pressures to be recognised; check the tyre pressures after all operations.
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.
Tyre pressure faults
The table on the following page lists the warning messages which appear on the instrument panel 1 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). For your safety, the warning light ® requires you to stop immediately as soon as traffic conditions allow.
Indicator lights | Messages | Displays | Readings |
|---|---|---|---|
| Adjust Tyre Pressure |
| The wheel and associated pressure value are displayed in yellow. This indicates that tyre under-inflation has been detected. Check and adjust the pressure of the four tyres then reset the system. |
+ ® | Puncture |
| The wheel and associated pressure value are displayed in red. This indicates that the tyre concerned is punctured or severely underinflated. Adjust the pressure of the four tyres while cold and reset the system if the tyre is deflated. Replace the tyre (or have it replaced) if it is punctured. |
+ © | Check Tyre Pressure Sensors |
| A wheel is no longer displayed. This indicates that at least one wheel is not fitted with a sensor (e.g. emergency spare wheel) or that the sensor is faulty. Consult an approved dealer. |
| Tyre Detection Failure |
| This indicates that the system has not been able to determine the pressure of each tyre. This may be caused by the use of a sensor not recommended by an approved dealer. The tyre pressure sensor monitoring system remains in operation. |
