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

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
