MOBILITY
Icon Possible cause
There is a flat tire or a major tire pres‐
sure loss.
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 are labeled with a circular icon
containing the letters RSC marked on the tire
sidewall.
Run-flat tires, refer to page 326.
Actions in the event of a flat tire
Normal tires
1. Identify the damaged tire.
To do this, check the tire pressure in all four
tires, for instance using the tire pressure dis‐
play of a flat tire kit.
When the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor FTM may not
have been initialized. In this case, initialize the
system.
If identification of flat tire damage is not pos‐
sible, please contact a dealer's service center
or another qualified service center or repair
shop.
2. Repair the flat tire, e.g., with a flat tire kit or by
changing the wheel.

Safety information
Warning
The vehicle handles differently when a run-flat
tire has insufficient or no tire pressure; for in‐
stance, reduced lane stability when braking,
braking distances are longer and the self-steer‐
ing properties will change. There is a risk of ac‐
cident. Drive moderately and do not exceed a
speed of 50 mph/80 km/h.
Maximum speed
You may continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
Follow the following when continuing to drive
with a damaged tire:
1. Avoid sudden braking and steering maneu‐
vers.
2. Do not exceed a speed of 50 mph/80 km/h.
3. Check the tire inflation pressure in all four
tires at the next opportunity.
When the tire inflation pressure in all four tires
is correct, the Flat Tire Monitor may not have
been initialized. In this case, initialize the sys‐
tem.
Possible driving distance with a
depressurized tire
The distance for which it may be possible to
drive safely varies depending on how the vehicle
is loaded and used, e.g., speed, road conditions,
outside temperature. The driving distance may
be less but may also be more if an economical
driving style is used.
If the vehicle is loaded with an average weight
and used under favorable conditions, the dis‐
tance for which it may be safe to drive may be up
to 50 miles/80 km.
