sized tire of the same type as on the vehi-
cle, and it is fully functional.However, that spare wheel rim is weight
optimized and has a limited service life of
12 000 miles (20 000 km) use before a
standard wheel rim must replace it.

spare wheel mounted.
For more information, see “Rims and tires”
(
page 426).

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, es-
pecially 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.
