Warning!G
The jack is designed exclusively for jacking 
up the vehicle under the axle housing. 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 sup-
ported 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 is posi-
tioned correctly under the axle housing. Al-
ways lower the vehicle onto sufficient 
capacity jackstands before working under 
the vehicle.

Mounting the spare wheel
Prepare the vehicle (page 348).
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.
Always try lifting the vehicle using the jack 
on a level surface. However, should cir-
cumstances require you to do so on a hill, 
place the wheel chocks as follows:
Place chocks on the downhill side 
blocking both wheels of the axle not 
being worked on.
Wheel wrench
On wheel to be changed, loosen but do 
not yet remove the wheel bolts (ap-
proximately one full turn with wrench). 
Warning!G
The jack is designed exclusively for jacking 
up the vehicle under the axle housing. 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 sup-
ported 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 is posi-
tioned correctly under the axle housing. Al-
ways lower the vehicle onto sufficient 
capacity jackstands before working under 
the vehicle.
If the vehicle is not raised as described, it 
could slip off the jack as a result of vibra-
tions (e.g. opening or closing a door or the
