The system must be reinitialized each time a tire inflation pressure has been corrected or a wheel or tire has been changed.< The Flat Tire Monitor is unable to warn the driver of sudden, severe tire damage caused by external 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 Initializing the system The initialization is completed during driving, which can be interrupted at any time. When driving resumes, the initialization is continued automatically. Do not initialize the system while snow chains are attached.< Reference 9. Start to drive. Initialization is completed while the car is on the move, without any feedback. Mobility Communications Entertainment System limitations Navigation Driving tips At a glance

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.
In the event of pressure loss, the rolling circum-
ference changes and, thus, the rotating speed
of the affected wheel. 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.
The system must be reinitialized each
time a tire inflation pressure has been cor-
rected or a wheel or tire has been changed.
<
System limitations
The Flat Tire Monitor is unable to warn
the driver of sudden, severe tire damage
caused by external 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
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 while snow chains
are attached.
