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 miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. Run-
flat tires can maintain limited stability. There is
a risk of an accident. Do not continue driving if
the vehicle is equipped with normal tires. Fol‐
low the information on run-flat tires and contin‐
ued 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
message 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
normal tires or run-flat tires.
Run-flat tires, refer to page 214, are la‐
beled with a circular symbol containing the
letters RSC marked on the tire's sidewall.
System limits
The system could be delayed or malfunction in
the following situations:
▷ A natural, even tire inflation pressure loss
in all four tires will not be recognized.
Therefore, check the tire inflation pressure
regularly.
▷ Sudden serious tire damage caused by ex‐
ternal circumstances cannot be recognized
in advance.
▷ When the system has not been initialized.
▷ When driving on a snowy or slippery road
surface.
▷ Sporty driving style: spinning traction
wheels, high lateral acceleration (drifting).
▷ When driving with snow chains.
Actions in the event of a flat tire
Normal tires
1.
Identify the damaged tire.
Check the air pressure in all four tires, e.g.,
using the tire pressure gage of a tire repair
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 system.
If identification of flat tire damage is not
possible, please contact a dealer’s service
center or another qualified service center
or repair shop.
2.
Repair the flat tire, e.g., with a tire repair kit
or by changing the tire.
