The pressure is too low in one or
more tires.

Carefully bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers. Observe
the traffic situation around you.

Check and adjust the tire inflation pressure as re-
quired (
page 308).

If necessary, change the wheel (
page 388).

Reactivate the Run Flat Indicator after adjusting
the tire inflation pressure values (
page 284).
Check tires
Then reactivate
