Rear Position–All Other Models
For all other models, position the
jack under the rear axle between
the spring anchor and the shock
absorber bracket.
If you have added a snow plow
to the front of your vehicle, lower
the snow plow fully before
raising the vehicle.
Make sure that the jack head is
positioned so that the rear axle
is resting securely between
the grooves that are on the
jack head.
{WARNING
Getting under a vehicle when it
is jacked up is dangerous. If the
vehicle slips off the jack, you
could be badly injured or killed.
Never get under a vehicle when
it is supported only by a jack.
{WARNING
Raising the vehicle with the
jack improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle. 6. Turn the wheel wrench
clockwise to raise the vehicle.
Raise the vehicle far enough off
the ground so there is enough
room for the spare tire to fit
under the wheel well.
