Initializing system
The initialization finishes during driving, 
which can be interrupted at any time. 
When driving resumes, the initialization is con-
tinued automatically. The system is initialized 
after this activation phase.
The initialization process adopts the set infla-
tion tire pressures as reference values for the 
detection of a flat tire. Initialization is started by 
confirming the inflation pressures.
The system is not initialized when traveling with 
snow chains

The initialization finishes during driving, which 
can be interrupted at any time. "Flat Tire Moni-
tor active" is displayed on the Control Display.
Indication of a flat tire
The warning lamp lights up red. A mes-
sage appears on the Control Display. 
In addition, an acoustic signal sounds. 
There is a flat tire or extensive inflation pressure 
loss.
1.
Cautiously reduce the vehicle speed to 
below 50 mph/80 km/h. Avoid severe brak-
ing and steering maneuvers and do not 
exceed a speed of 50 mph/80 km/h.
Stop driving if the vehicle is no longer 
equipped with run-flat tires, as it was 
when it came from the factory, refer to 
page
. Continued driving after a flat tire 
can result in serious accidents.

2.
At the next opportunity, check the air pres-
sure in all four tires.
If the tire inflation pressure in all four 
tires is correct, the Flat Tire Monitor 
may not have been initialized. The system 
must then be initialized.

3.
In the event of complete tire pressure loss, 
0 psi/0 kPa, you can estimate the possible 
distance for continued driving on the basis 
of the following guide values:
>
With a light load: 
1 to 2 persons without luggage: 
approx. 155 miles/250 km
>
With a medium load: 
2 persons, cargo bay full, or 
4 persons without luggage: 
approx. 94 miles/150 km
>
With a full load: 
4 persons, luggage compartment full: 
approx. 30 miles/50 km
Drive reservedly and do not exceed a 
speed of 50 mph/80 km/h. In the 
event of pressure loss, vehicle handling 
changes. This includes reduced tracking 
stability in braking, extended braking dis-
tance and altered natural steering charac-
teristics.
When towing a trailer, heavy trailers in par-
ticular can begin to swing back and forth. 
Therefore, do not exceed 35 mph/60 km/h, 
otherwise there is the danger of an acci-
dent.
If unusual vibrations or loud noises occur 
while the vehicle is being driven, this can 
indicate final failure of the damaged tire. 
Reduce speed and stop at a suitable loca-
tion as soon as possible, otherwise pieces 
of the tire could become detached and
