System which automatically checks the pressures of the tyres while driving.
The system monitors the pressures in the four tyres, once the vehicle is moving. It compares the information given by the four wheel speed sensors with reference values, which must be reinitialised ever y time the tyre pressures are adjusted or a wheel changed . The system triggers an alert as soon as it detects a drop in the inflation pressure of one or more tyres.
The under-inflation detection system does not replace the need for vigilance on the part of the driver. This system does not avoid the need to check the tyre pressures (including the spare wheel) every month as well as before a long journey. Driving with under-inflated tyres impairs road holding, extends braking distances and causes premature tyre wear, particularly under arduous conditions (high loading, high speed, long journey).
The inflation pressures defined for your vehicle can be found on the tyre pressure label. For more information on the identification markings, refer to the corresponding section. Tyre pressures should be checked when the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10 km) at moderate speeds). Other wise (when hot), add 0.3 bar to the pressures shown on the label.
Driving with under-inflated tyres increases fuel consumption.
Under-inflation alert
This is given by fixed illumination of this warning lamp, accompanied by an audible signal and, depending on equipment, the display of a message.
Reduce speed immediately, avoid excessive steering movements and sudden braking. Stop the vehicle as soon as it is safe to
do so.
The loss of pressure detected does not always cause visible bulging of the tyre. Do not satisfy yourself with just a visual check.
The alert is maintained until the system is reinitialised.
In the event of a puncture, use the temporary puncture repair kit or the spare wheel (depending on equipment), or if you have a compressor, such as the one in the temporary puncture repair kit, check the pressures of the four tyres when cold, or if it is not possible to make this check immediately, drive carefully at reduced speed.
