Troubleshooting for Tyre Pressure Loss Indicator
Low tyre pressure
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 continue driving!
—Check and adjust all tyre pressures (→ Tyre pressure, Introduction/General information).
—Damaged tyres should be replaced.
—Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator, Function).
—If the problem persists, go to a qualified workshop.
Fault in the Tyre Pressure Loss Indicator
The indicator lamp flashes for around 65 seconds and then remains lit up yellow continuously.
There is a system fault.
—
Do not continue driving!
—Switch the ignition off and then back on again.
—Re-synchronise the Tyre Pressure Loss Indicator (→ Tyre Pressure Loss Indicator, Function).
—If the problem persists, go to a qualified workshop.
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, Introduction/General information).
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,
Introduction/General information).

The tyre monitoring system cannot function correctly unless all cold tyres have the correct
tyre pressure.
The pressure in all tyres must always be appropriate to the vehicle load (→ Tyre pressure,
Introduction/General information).
Always inflate all tyres to the correct tyre pressure before every journey (→ Tyre pressure,
Introduction/General information).
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, Introduction/General information).
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 65 seconds and then light up continuously. However, the indicator
lamp will go out when the road conditions or driving style change.
