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. Al-
ways lower the vehicle onto sufficient ca-
pacity jackstands before working under the
vehicle.

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.

304 Practical hintsWhere will I find ...?In the 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”
(

steel rims. The use of any wheel bolts
other than wheel bolts2 for the
Minispare wheel or other steel rims will
physically damage the vehicle’s
