Possible driving distance with a flat tire
The possible driving distance which may be
safely traveled varies depending on how the
vehicle is loaded and used, e.g., speed, road
conditions, outside temperature. The distance
traveled may be less but may also be more if
an economical driving style is used.
If the vehicle is loaded with an average
weight and used under favorable conditions,
the possible distance traveled may be up to
50 miles/80 km.
Vehicle handling with damaged tires
Vehicles driven with a damaged tire will han-
dle differently, potentially leading to conditions
such as the following:
▷
Greater likelihood of skidding of the vehicle.
▷
Longer braking distances.
▷
Changed self-steering properties.
Modify your driving style. Avoid abrupt steering
or driving over obstacles, for instance curbs or
potholes.
Final tire failure
Vibrations or loud noises while driving can indi-
cate the final failure of a tire.
Reduce speed and stop; otherwise, pieces of
the tire could come loose and cause an acci-
dent.
Do not continue driving. Contact an authorized
service center or another qualified service cen-
ter or repair shop.
System limits
Temperature
The tire inflation pressure depends on the
tire's temperature.
Driving or exposure to the sun will increase the
tire temperature, thus increasing the tire infla-
tion pressure.
The tire inflation pressure is reduced when the
tire temperature falls again.

Wheels and tires
These circumstances may cause a warning
when temperatures fall very sharply.
Following a temperature-related warning, the
target pressures are displayed on the control
display again after a short distance.
Sudden tire pressure loss
The system cannot indicate sudden and se-
rious tire damage caused by external circum-
stances.
Failure performing a reset
Tires with special approval: the system will not
function correctly if a reset was not performed,
for example a flat tire may be indicated al-
though the tire inflation pressures are correct.
Malfunction
Message
The yellow warning light flashes and is
then illuminated continuously. A Check
Control message is displayed. It may
not be possible to identify tire pressure losses.
Measure
▷
A wheel without air pressure sensor is
mounted: Have the wheels checked as
needed.
▷
Fault caused by systems or devices with
the same transmission frequency: The sys-
tem automatically reactivates after leaving
the area of the interference.
▷
For tires with special approval: the system
was unable to complete the reset. Perform
a system reset again.
▷
If the Tire Pressure Monitor malfunctions:
Have the vehicle checked by an authorized
service center or another qualified service
center or repair shop.
