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
accident. Do not continue driving if the vehicle
is equipped with normal tires. Follow the infor‐
mation on run-flat tires and continued driving
with these tires.
If a tire inflation pressure check is
required
Message
An icon with a Check Control message appears
on the Control Display.
Icon 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.
Measure
1. Check the tire pressure and correct as
needed.
2. Perform a system reset.
