Continued driving with a flat tire
Follow the following when continuing to
drive with a damaged tire:
1. Avoid sudden braking and steering ma-
neuvers.
2. Do not exceed a speed of
50 mph/80 km/h.
3. Check the tire inflation pressure in all
four tires at the next opportunity.
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
handle differently, potentially leading to
conditions such as the following:
– Greater likelihood of skidding of the ve-
hicle.
– Longer braking distances.
– Changed self-steering properties.
Modify your driving style. Avoid abrupt
steering or driving over obstacles, for in-
stance curbs or potholes.
Final tire failure
Vibrations or loud noises while driving can
indicate the final failure of a tire.
Reduce speed and stop; otherwise, pieces
of the tire could come loose and cause an
accident.
Do not continue driving. Contact an author-
ized service center or another qualified
service center 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 inflation pressure.
The tire inflation pressure is reduced when
the tire temperature falls again.
These circumstances may cause a warning
when temperatures fall very sharply.
Following a temperature-related warning,
the nominal pressures are shown on the In-
teraction Unit again after driving for a short
time.
Sudden tire pressure loss
The system is not able to indicate sudden
and serious tire damage and the resulting
loss of tire pressure caused by external cir-
cumstances.
Failure performing a reset
When using tires with special approval, the
system will not function correctly if it has
not been reset. For example, a flat tire may
be indicated although the tire pressures are
correct.
Malfunction
Message
The Tire Pressure Monitor displays a mes-
sage if the system is not operational.
The yellow warning light flashes and
is then illuminated continuously. A
Check Control message is displayed.
