Malfunction
The warning lamps for the brake sys-
tem light up in yellow. The drive-off 
assistant has failed. The car will not 
be held in place after the brake is 
released. Have the system checked as soon as 
possible.
Canadian models display these warn-
ing lamps.
Flat Tire Monitor FTM
The concept
The Flat Tire Monitor monitors tire pressures 
while the car is being driven. The system 
reports any significant loss of pressure in one 
tire in relation to another.
If a tire loses pressure, its rolling radius 
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.
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
>
If 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.
