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.
Indication of a flat tire
A yellow warning light is illuminated in
the instrument cluster.
In addition, an icon with a Check Control mes‐
sage appears on the Control Display.
Icon Possible cause
There is a flat tire or a major tire pres‐
sure loss.
Measure

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 are labeled with a circular icon
containing the letters RSC marked on the tire
sidewall.
