Runflat tires
Safety information
Warning
The vehicle handles differently when a runflat
tire has insufficient or no tire pressure; for
instance, reduced directional stability when
braking, braking distances are longer and the
self-steering properties will change. There is
a risk of accident. Drive moderately and do
not exceed a speed of 50 mph/80 km/h.
Maximum speed
You may continue driving with a damaged tire
at speeds up to 50 mph/80 km/h.
Continued driving with a flat tire
Follow the following when continuing to drive
with a damaged tire:
1.
Avoid sudden braking and steering maneu-
vers.
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 distance traveled with a
depressurized tire
The possible distance which may be safely
traveled varies depending on how the vehicle
is loaded and used, e.g., speed, road condi-
tions, outside temperature. The distance trav-
eled 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.
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 serious
tire damage caused by external circumstances.
