Performing initialization
When initializing, the set tire inflation pressures
serve as reference values in order to detect a flat
tire. Initialization is started by confirming the tire
inflation pressures.
Do not initialize the system when driving with
snow chains.
Via iDrive:
1. "CAR"
2. "Vehicle status"
3. "Flat Tire Monitor"
4. Switch on drive-ready state and 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.

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 317, 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.
