Preparing the vehicle
Take vehicle tool kit tray and vehicle
jack out of trunk.
Take the spare wheel out of wheel well
(page 379).
Lifting the vehicle
Prevent the vehicle from rolling away
by blocking wheels with wheel chocks
(not included) or other sizable objects.
When changing wheel on a level surface:
Place one chock in front of and one be-
hind the wheel that is diagonally oppo-
site to the wheel being changed.
When changing wheel on a hill:
Place chocks behind the downhill sides
of both wheels of the axle not being
worked on.
Take the two-piece wheel wrench out
of the vehicle tool kit tray. Assemble
wheel wrench.
On wheel to be changed, loosen but do
not yet remove the wheel bolts (ap-
proximately one full turn with wrench).
The tube openings are located directly be-
hind the front wheel housings and in front
of the rear wheel housings.
The dimensions of the spare wheel are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a mounted spare
wheel. Adapt your driving style accordingly.
Warning!
G
The jack is designed exclusively for jacking
up the vehicle at the jack tubes built 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 un-
der the lifted vehicle. Always firmly set park-
ing 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 inserted in the jack tube. Always lower
the vehicle onto sufficient capacity jack-
stands before working under the vehicle.
