The indicator lamp lights up yellow.
There is a loss of pressure in one or more tyres or the tyre is structurally damaged.
—
Do not drive on!
—Check and adjust all tyre pressures (→ Tyre pressure).
—The damaged tyre should be replaced.
—Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator).
—If the fault persists, seek expert assistance.
Fault in the Tyre Pressure Loss Indicator
The indicator lamp flashes for around 1 minute and then remains lit up yellow continuously.
There is a system fault.
—
Do not drive on!
—Switch the ignition off and then back on again.
—Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator).
—If the fault persists, seek expert assistance.
WARNING
Differing tyre pressures or tyre pressures that are too low can cause tyre damage, tyre failure, loss of vehicle
control, accidents, serious injury and death.
● If the indicator lamp lights up, stop the vehicle as soon as possible and check all the tyres (→ Tyre pressure).
● Different tyre pressures or tyre pressures that are too low can increase wear on the tyres, reduce vehicle stability
and increase the braking distance.
● Differing tyre pressures or tyre pressures that are too low can cause sudden tyre failure and lead to a tyre
bursting and the loss of control over the vehicle.
● The driver is responsible for the correct tyre pressure of all tyres on the vehicle. The recommended tyre pressure
can be found on a sticker (→ Tyre pressure).
● The tyre monitoring system cannot function correctly until all cold tyres have the correct tyre pressure.
● The pressure in all tyres must always be appropriate to the vehicle load (→ Tyre pressure).
● Always inflate all tyres to the correct tyre pressure before every journey (→ Tyre pressure).
● If the vehicle is driven with insufficient tyre pressure, this results in greater tyre flexing. This could warm up the
tyre to such an extent that the tread may separate and the tyre could burst. This could cause the driver to lose
control of the vehicle.
● High speeds and overloading of the vehicle may cause the tyres to heat up to such an extent that the tyre bursts,
leading you to lose control of the vehicle.
● If the tyre pressure is too low or too high, the tyres will wear prematurely and the vehicle will not handle well.
● If the tyre is not flat and it is not necessary to change the wheel immediately, drive at low speed to the nearest
qualified workshop and check and correct the tyre pressure (→ Tyre pressure).
● The Tyre Pressure Loss Indicator must always be calibrated correctly.
Driving on unpaved roads for long periods, or a sporty driving style, can temporarily deactivate the Tyre
Pressure Loss Indicator. In the event of a malfunction, the indicator lamp will flash for around one minute and
then light up continuously. However, the indicator lamp will go out when the road conditions or driving style
change.
