TYRE PRESSURE MONITOR
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:
- repeatedly tap the 5 switch as many times as necessary to reach the “vehicle” tab ;
- 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.
Steps | Displays (depending on the vehicle) | Messages | Readings |
|---|---|---|---|
1 |
| Tyre pressure init. long press | With the ignition on and the vehicle stationary, start the resetting the pressure of all four tyres by pressing and holding the 4 OK switch. |
2 |
| Learning Tyre Pressures | The “---” quote marks in front of each wheel will flash to indicate that the system has registered the tyre pressure reset for all four wheels. |
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 pressure of the four tyres must be set when cold (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.
Emergency spare wheel
If the vehicle is equipped with an emergency spare wheel, it will not have a sensor.
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.). TYRES.
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.
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 see the section on TYRE PRESSURE KIT.
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 (depending on the vehicle) | 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. |
