Where will I find...?
In case of a flat tire, you may temporarily
use the Minispare wheel when observing
the following restrictions:

Do not exceed a vehicle speed of
50 mph (80 km/h).

Drive to the nearest tire repair facility
to have the flat tire repaired or
replaced as appropriate.

Do not operate vehicle with more than
one Minispare wheel mounted.

(located in trunk with spare wheel)
!To prevent damage, always disengage trunk
floor handle from upper edge of trunk and lower
trunk floor before closing the trunk.
Warning!G
The dimensions of the Minispare wheel are
different from those of the road wheels. As
a result, the vehicle handling characteristics
change when driving with a Minispare wheel
mounted.
The Minispare wheel should only be used
temporarily, and should be replaced with a
regular road wheel as quickly as possible.
Do not switch off the ESP
® when a Minis-
pare wheel is mounted.
!Wheel bolts2 must be used when mount-
ing the Minispare wheel. The use of any wheel
bolts other than wheel bolts2 for the Minispare
wheel will physically damage the vehicle’s
brakes.
Warning!G
Make sure to use the original length wheel
bolts when remounting the original wheel
after it has been repaired.
