Sym‐
bol Possible cause
The tyre was not inflated properly, for
example insufficient air added.
The system has detected a wheel
change, but no reset has been run.
The tyre inflation pressure has drop‐
ped compared to the last reset.
No reset has been performed on the
system. The system uses the tyre in‐
flation pressures saved during the
last reset for the warning.
Measure
1. Check the tyre inflation pressure and adjust
as necessary.
2. Perform a reset of the system.
If the tyre inflation pressure is
insufficient
Message
A yellow warning lamp is illuminated in
the instrument cluster.
In addition, a symbol with a Check Control mes‐
sage is shown on the Control Display.
Symbol Possible cause
There has been a loss of tyre infla‐
tion pressure.
No reset has been performed on the
system. The system uses the tyre in‐
flation pressures saved during the
last reset for the warning.
Measure
1. Reduce speed. Do not exceed a speed of
130 km/h, 80 mph.
2. At the next opportunity, for example at a filling
station, check the tyre inflation pressure in all
four tyres and correct if necessary.
3. Perform a reset of the system.
If there is a significant loss of tyre
inflation pressure
Message
A yellow warning lamp is illuminated in
the instrument cluster.
In addition, a symbol with the affected tyre is
shown in a Check Control message on the Con‐
trol Display.
Symbol Possible cause
There is a flat tyre or substantial loss
of tyre inflation pressure.
No reset has been performed on the
system. The system uses the tyre in‐
flation pressures saved during the
last reset for the warning.
Measure
1. Reduce your speed and carefully stop the ve‐
hicle. Avoid violent or sudden braking and
steering manoeuvres.
2. Check whether the vehicle is equipped with
standard tyres or run-flat tyres.
The symbol identifying run-flat tyres, see
page
311 , is a circle with the letters RSC on
the tyre side wall.
What to do in the event of a flat
tyre
Standard tyres
1. Identify the damaged tyre.
Check the tyre inflation pressure in all four
tyres, for example using the tyre pressure in‐
dicator of a flat tyre kit.
In the case of tyres with special approval: if all
four tyres are inflated to the correct tyre infla‐
tion pressures, the TPM might not have been
reset. Perform a reset.
