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 heavy braking and sudden steer‐
ing manoeuvres.
2. Check whether the vehicle is equipped with
standard tyres or run-flat tyres.
The symbol identifying run-flat tyres, see
page
341 , is a circle with the letters RSC on
the tyre side wall.
3. Follow the description of what to do in the
event of a flat tyre, see page
351 .
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.
If no tyre damage can be found, contact a
Service Partner of the manufacturer or an‐
other qualified Service Partner or a specialist
workshop.
2. Repair the flat tyre, for example using a flat
tyre kit or by changing the wheel.
The use of sealant, for example a flat tyre kit, can
damage the TPM wheel electronics. Have the
electronics replaced at the next opportunity.
Run-flat tyres
Safety notes
WARNING
A run-flat tyre which has low tyre inflation pres‐
sure or no tyre inflation pressure at all will
change the vehicle's handling characteristics,
for example there may be reduced directional
stability when braking, longer braking distances
and different self-steering characteristics.
There is a risk of accident. Drive with care and
do not exceed a speed of 80 km/h, 50 mph.
