reset.
1. Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
vers.

beled with a circular symbol containing the
letters RSC marked on the tire sidewall.
Do not continue driving without run-flat

Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀
When a low inflation pressure is indicated,
DSC Dynamic Stability Control is switched on
if necessary.
Actions in the event of a flat tire
