that prevent the TPMS from functioning prop-
erly. Always check the TPMS malfunction tell-
tale after replacing one or more tires or wheels
on your vehicle to ensure that the replacement
or alternate tires and wheels allow the TPMS
to continue to function properly.
Flat Tire Monitor
Principle
The Flat Tire display detects a tire pressure
loss while driving and issues a warning if the
tire pressure has dropped.
General information
The system detects tire pressure loss on the
basis of rotation speed differences between
the individual wheels while driving.
In the event of a tire pressure loss, the diame-
ter and therefore the rotational speed of the
corresponding wheel changes. The difference
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 prerequisites must be met for
the system; otherwise, reliable message of a
tire pressure loss is not assured:
▷ After a tire or wheel change, an initialization
was carried out at the correct tire pressure.
▷ After the tire pressure was adjusted to a
new value, an initialization was performed.
Status display
The current status of the flat tire monitor can
be displayed, e.g., whether the flat tire monitor
is active.
1. "MENU"
2. "Vehicle apps"
3. "Live Vehicle"
4. "Content"
5. "Vehicle status"
6. "Flat Tire Monitor"
The status is displayed.
Initialization required
An initialization must be performed in the fol-
lowing situations:
▷ After the tire inflation pressure has been
adjusted.
▷ After a tire or wheel change.
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
tire chains.
1. "MENU"
2. "Vehicle apps"
3. "Live Vehicle"
4. "Content"
5. "Vehicle status"
6. "Flat Tire Monitor"
7. Turn on drive-ready state and do not drive
off.
8. Start the initialization with: "Perform reset"
9. Drive away.
The initialization is completed while driving,
which can be interrupted at any time.
The initialization automatically continues when
driving continues.
Messages
General information
