on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure. Un‐
der-inflation also reduces fuel efficiency and
tire tread life, and may affect the vehicle's han‐
dling and stopping ability. Please note that the
TPMS is not a substitute for proper tire mainte‐
nance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-in‐
flation 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 continu‐
ously illuminated. This sequence will continue
upon subsequent vehicle start-ups as long as
the malfunction exists. When the malfunction
indicator is illuminated, the system may not be
able to detect or signal low tire pressure as in‐
tended. TPMS malfunctions may occur for a va‐
riety of reasons, including the installation of re‐
placement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re‐
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
FTM Flat Tire Monitor
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.

Safety
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 initial‐
ization was performed with the correct tire
inflation pressure.
▷ After the tire inflation pressure was ad‐
justed 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 the Central Information Display (CID):
1. "Vehicle info"
2. "Vehicle status"
3. "Flat Tire Monitor (FTM)"
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 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 the Central Information Display (CID):
1. "Vehicle info"
2. "Vehicle status"
3. "Perform reset"
4. Start the engine but do not drive off.
