Warning!G
The jack is designed exclusively for jacking
up the vehicle at the jack take-up brackets
built into both sides of the vehicle. To help
avoid personal injury, use the jack only to lift
the vehicle during a wheel change. Never
get beneath the vehicle while it is supported
by the jack. Keep hands and feet away from
the area under the lifted vehicle. Always
firmly set parking brake and block wheels
before raising vehicle with jack.
Do not disengage parking brake while the
vehicle is raised. Be certain that the jack is
always vertical (plumb line) when in use,
especially on hills. Always try to use the jack
on level surface. Make sure the jack arm is
fully seated in the jack take-up bracket.
Always lower the vehicle onto sufficient
capacity jackstands before working under
the vehicle.

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.
For more information, see “Rims and tires”
(
page 482).

(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.
