Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
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, refer to page 307, are labeled
with a circular symbol containing the letters
RSC marked on the tire's sidewall.
Actions in the event of a flat tire
Normal tires
1.
Identify the damaged tire.
To do this, check the tire inflation pressure in
all four tires, for instance using the tire pres‐
sure gage of a flat tire kit.
If 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.
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.
Run-flat tires
Safety information
WARNING
Your vehicle handles differently with a run-flat
with no or low inflation pressure; for instance,
your lane stability when braking is reduced,
braking distances are longer and the self-steer‐
ing properties will change. There is a risk of an
accident. 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.
If 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 range 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,
external temperature. The driving range may be
less but may also be more if an economical driv‐
ing 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.
Vehicle handling with damaged tires
Vehicles driven with a damaged tire will handle
differently, potentially leading to conditions such
as the following:
▷ Greater likelihood of swerving off course.
▷ Longer braking distances.
▷ Changed self-steering properties.
