Flat Tire Monitor FTM*
The concept
The Flat Tire Monitor detects pressure loss in a
tire by comparing the rotating speeds of the
individual tires while moving.
If a tire loses pressure, its rolling circumference
changes, and this in turn alters the speed of
rotation. This change is detected and is reported
as a flat tire.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be initialized for the cor-
rect tire inflation pressure.
Each time you correct the pressure in a
tire, or change a wheel or tire, the system
must be reinitialized.<
System limitations
The Flat Tire Monitor is unable to warn the driver
of sudden, severe tire damage caused by exter-
nal factors, nor can it identify the gradual loss of
pressure that will inevitably occur in all four tires
over a lengthy period of time.In the following situations, the system could be
delayed or malfunction:
>System has not been initialized
>Driving on snowy or slippery road surface
>Performance-oriented style of driving: slip in
the drive wheels, high lateral acceleration
>Snow chains are attached
When the vehicle is driven with a space-saver
spare tire
*, page133, the Flat Tire Monitor can-
not function.
Initializing the system
The initialization is completed during driv-
ing, which can be interrupted at any time.
When driving resumes, the initialization is con-
tinued automatically.
Do not initialize the system if you are driving
with snow chains or a space-saver spare tire
*.<
Using the button in the turn indicator
lever
1.Start the engine, but do not start driving.
2.Briefly press the button in the turn indicator
lever repeatedly until "SET/INFO" is dis-
played.
3.Press and hold the button until the display
changes.

Tire Pressure Monitor
TPM*
The concept
TPM checks the tire pressure in the four
mounted tires during driving. The system noti-
fies you if there is a significant loss of pressure in
one or more tires.
Functional requirement
In order to assure the reliable reporting of a flat
tire, the system must be reset while all tire infla-
tion pressures are correct.
Always use wheels with TPM electronics. Other-
wise, the system may malfunction.
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
System limitations
TPM cannot warn you in advance of sud-
d e n s e v e r e t i r e d a m a g e c a u s e d b y o u t s i d e
influences.<
The system does not work correctly if it has not
been reset; for example, a flat tire may be indi-
cated even though the tire inflation pressures
are correct.
The system is inactive and cannot indicate a flat
tire if a wheel without TPM electronics, such as a
compact spare wheel
*, has been mounted, or if
TPM is temporarily malfunctioning due to other
systems or devices using the same radio fre-
quency.
Resetting the system
Each time a tire inflation pressure has
been corrected or a wheel or tire has been
changed, reset the system.<
Using the button in the turn indicator
lever
1.Start the engine, but do not start driving.
2.Briefly press the button in the turn indicator
lever repeatedly until "SET/INFO" is dis-
played.3.Press and hold the button until the display
changes.
4.Briefly press the button repeatedly until the
symbol for Tire Pressure Monitor and
"ACTIVE" are displayed.
The Tire Pressure Monitor can be reset by
selecting "RESET".
5.Press and hold the button until "RESETTING"
is displayed.
6.Start driving.
After driving a few minutes, the set inflation
pressures in the tires are accepted as the tar-
get values to be monitored. The system
reset is completed during your drive, and
c a n b e i n t e r r u p t e d a t a n y t i m e . W h e n d r i v i n g
resumes, the reset is continued automati-
cally. The indicator lamp goes out after the
system reset is completed.
