Safety information
A damaged regular tire with low or missing tire
inflation pressure impacts handling, such as
steering and braking response. Run-flat tires
can maintain limited stability. There is a risk of
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, a symbol with a Check Control mes‐
sage appears on the Control Display.
Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
Reduce your speed and stop cautiously.
Avoid sudden braking and steering maneu‐
2. Check whether the vehicle is fitted with nor‐
mal tires or run-flat tires.
Run-flat tires, refer to page 296, 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

sible, please contact a dealer’s service center
or another qualified service center or repair

changing the wheel.
Run-flat tires
Safety information
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.
Heavy trailers can start swinging when continu‐
ing to drive with a flat tire. There may be a risk
of accident or risk of damage to property. Do
not exceed a speed of 35 mph/60 km/h when
driving with a trailer and a flat tire. Immediately
brake in the case of swinging. Apply necessary
steering corrections as carefully as possible.
Maximum speed
You may continue driving with a damaged tire at
speeds up to 50 mph/80 km/h.
