In the event of a tire inflation pressure loss, the
diameter and therefore the rotational speed of
the corresponding wheel changes. The differ‐
ence will be detected and reported as a flat tire.
The system does not measure the actual infla‐
tion pressure in the tires.
Functional requirements
The following conditions must be met for the
system; otherwise, reliable flagging of a loss of
tire inflation pressure is not assured:
▷ After a tire or wheel replacement, an initializa‐
tion was performed with the correct tire infla‐
tion pressure.
▷ After the tire inflation pressure was adjusted
to a new value, an initialization was per‐
formed.
Status display
The current status of the flat tire monitor can be
displayed, for instance whether the RPA is active.
Via iDrive:
1.
"My Vehicle"
2. "Vehicle status"
3. "Flat Tire Monitor"
The status is displayed.
Initialization required
An initialization must be performed in the follow‐
ing situations:
▷ After the tire inflation pressure has been ad‐
justed.
▷ After a tire or wheel replacement.
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. "My Vehicle"
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.
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 missing 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 mes‐
sage appears on the Control Display.
Symbol Possible cause
There is a flat tire or a major loss in
tire inflation pressure.
