the system.
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.

Changing wheels/tires
General information
When using runflat tires or a tire repair set, the
wheel does not always need to be changed
immediately in the event of a breakdown when
there is tire pressure loss.
If necessary, a suitable wheel change tool, e.g.,
a jack, is available as an accessory from an
authorized service center or another qualified
service center or repair shop.
Safety information
Warning
The jack is only provided for short-term lifting
of the vehicle for wheel changes. Even if all
safety precautions are observed, there is a
risk of the raised vehicle falling if the jack tips
over. There is a risk of injury or danger to life.
When the vehicle is raised with the jack, do
not lie under the vehicle and do not switch on
the drive-ready state.
