Peugeot 2008: Driving / Under-inflation detection

This system automatically checks the pressures of the tyres while driving.

It compares the information given by the wheel speed sensors with reference values, which must be reinitialised every 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.

Under-inflation detection does not replace the need for vigilance on the part of the driver.

This system does not avoid the need to regularly check the tyre pressures (including the spare wheel), especially before a long journey.

Driving with under-inflated tyres, particularly in adverse conditions (heavy load, high speed, long journey):

• worsens road-holding.
• lengthens braking distances.
• causes premature wear of the tyres.
• increases energy consumption.

The inflation pressures defined for the vehicle can be found on the tyre pressure label.

For more information on the Identification markings, refer to the corresponding section.

Checking tyre pressures

This check should be done when the tyres are "cold" (vehicle stopped for 1 hour or after a journey of less than 6 miles (10  km) at moderate speeds).

Otherwise, add 0.3 bar to the pressures shown on the label.

 Snow chains

The system does not have to be reinitialised after fitting or removing snow chains.

Under-inflation alert

This is signalled by the 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 avoid 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 rely on just a visual check.

• Using a compressor, such as the one in the temporary puncture repair kit, check the pressures of the four tyres when cold.
• If it is not possible to make this check immediately, drive carefully at reduced speed.
• In the event of a puncture, use the temporary puncture repair kit or the spare wheel (depending on equipment).

The alert is kept active until the system is reinitialised.

Reinitialisation

Reinitialise the system after adjusting one or more tyre pressures and after changing one or more wheels.

Before reinitialising the system, make sure that the pressures of the four tyres are correct for the conditions of use of the vehicle and conform to the values written on the tyre pressure label.

Check the pressures of the four tyres before performing the reinitialisation.

The system does not advise if a pressure is incorrect at the time of reinitialisation.

With the vehicle stationary, the system is reinitialised via the  Driving / Vehicle  touch screen menu..

Malfunction

These warning lamps come on in the event of a malfunction.

A message appears, accompanied by an audible signal.

In this case, the tyre under-inflation monitoring function is no longer performed.

Have the system checked by a PEUGEOT dealer or a qualified workshop.
