Performing initialization
When initializing, the set tire inflation pres‐
sures serve as reference values in order to de‐
tect a flat tire. Initialization is started by con‐
firming the tire inflation pressures.
Do not initialize the system when driving with
snow chains.
Via iDrive:
1. "Vehicle info"
2. "Vehicle status"
3. "Perform reset"
4. Start the engine but do not drive off.
5. Start the initialization with "Perform reset".
6. Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving resumes.
Messages
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.

Online Edition for Part no. 01402983801 - X/17
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 243, are la‐
beled 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 air pressure in all four
tires, for instance using the tire pressure
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 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 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 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 an accident.
