Symbol Possible cause
There is a tire inflation pressure loss.
Measure
1. Reduce the vehicle speed. Do not exceed a
speed of 80 mph/130 km/h.
2. At the next opportunity, for instance at a gas
station, check the tire inflation pressure in all
four tires and correct if necessary.
If there is a significant loss of tire
inflation pressure
Message
A yellow warning light is illuminated in
the instrument cluster.
In addition, a symbol with the affected tire ap‐
pears in a Check Control message on the Con‐
trol Display.
Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
Measure
1.
Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.
2. Check whether the vehicle is fitted with nor‐
mal tires or run-flat tires.
Run-flat tires, refer to page 307, are labeled
with a circular symbol containing the letters
RSC marked on the tire's sidewall.
Messages: for tires with special
approval
General information
A low tire inflation pressure may cause the DSC
Dynamic Stability Control to be switched on.
Safety information
WARNING
A damaged regular tire with low or missing tire
inflation pressure impacts handling, such as
steering and braking response. Run-flat tires
can maintain limited stability. There is a risk of
an accident. Do not continue driving if the vehi‐
cle is equipped with normal tires. Follow the in‐
formation on run-flat tires and continued driving
with these tires.
If a tire inflation pressure check is
required
Message
A symbol with a Check Control message ap‐
pears on the Control Display.
Sym‐
bol
Possible cause
Inflation was not carried out accord‐
ing to specifications, e.g., the tire has
not been sufficiently inflated.
The system has detected a wheel
change, but no reset was done.
The tire inflation pressure has fallen
below the level of the last reset.
No reset was performed for the sys‐
tem. The system issues a warning
based on the tire inflation pressures
stored during the last reset.
