trol Display.
Symbol Possible cause
There is a flat tyre or substantial loss
of tyre inflation pressure.
Measure

hicle. Avoid heavy braking and sudden steer‐
ing manoeuvres.

standard tyres or run-flat tyres.
The symbol identifying run-flat tyres, see

Messages: in the case of tyres
with special approval
General
Dynamic Stability Control DSC will be activated if
necessary as soon as a message for low tyre in‐
flation pressure appears.
Safety note
WARNING
A damaged standard tyre with too little or no
tyre inflation pressure impairs driving character‐
istics, for example steering and braking. Tyres
with run-flat properties allow a limited level of
stability to be maintained. There is a risk of ac‐
cident. Do not continue driving if the vehicle is
fitted with normal tyres. Comply with the notes
on run-flat tyres and continuing to drive with
these tyres.
If a tyre inflation pressure check is
required
Message
A symbol with a Check Control message is
shown on the Control Display.
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 per‐
formed.
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.
