General information
When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on, if needed.
Safety information
Warning
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.
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 337, 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
tire with no or low inflation pressure; for in‐
stance, your lane stability when braking is re‐
duced, braking distances are longer and the
self-steering properties will change. There is a
risk of 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.
