ciency and tire tread life, and may affect the vehi‐
cle's handling and stopping ability. Please note
that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility
to maintain correct tire pressure, even if under-
inflation has not reached the level to trigger illu‐
mination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi‐
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal‐
function exists. When the malfunction indicator is
illuminated, the system may not be able to de‐
tect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Al‐
ways check the TPMS malfunction telltale after
replacing one or more tires or wheels on your ve‐
hicle to ensure that the replacement or alternate
tires and wheels allow the TPMS to continue to
function properly.
Flat Tire Monitor FTM
Concept
The system detects tire inflation pressure loss
on the basis of rotation speed differences be‐
tween the individual wheels while driving.
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 pressure was adjusted to a new
value, an initialization was performed.
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. Start the engine but do not drive off.
