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.
Using 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.

Safety information
WARNING
A damaged regular tire with low or miss‐
ing tire inflation pressure impacts handling,
such as steering and braking response. There
is a risk of an accident. Do not continue driving.
Repair the flat tire or replace the wheel.◀
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. Identify the damaged wheel. 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 tires is correct, the Flat Tire Monitor
may not have been initialized. In this case,
initialize the system.
3. Repair the flat tire, e.g., with a flat tire kit or
by changing the wheel.
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.
Intelligent Safety
Concept
Intelligent Safety enables central operation of
the driver assistance system. Depending on
how the vehicle is equipped, Intelligent Safety
consists of one or more systems that can help
prevent an imminent collision.
▷ Approach control warning with City light
braking function, refer to page 124.
▷ Pedestrian warning, refer to page 127.
