WHAT TO DO IN EMERGENCIES
Jacking Instructions
84
1. Remove the spare tire, jack and tools
from the stored location.
2. Loosen (but do not remove) the wheel
lug nuts by turning them to the left one
turn while the wheel is still on the
ground.
3. Assemble the jack and jacking tools.
Connect the jack handle driver to the
extension, then to the lug wrench.
4. Operate the jack from the front or the
rear of the vehicle. Place the jack
under the axle tube, as shown. Do not
raise the vehicle until you are sure
the jack is fully engaged.
5. Raise the vehicle by turning the jack
screw to the right. Raise the vehicle
only until the tire just clears the surface
and enough clearance is obtained to
install the spare tire. Minimum tire lift
provides maximum stability.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the
vehicle and install the lug nuts with the
cone-shaped end toward the wheel.
Lightly tighten the lug nuts clockwise.
8. Lower the vehicle by turning the jack
screw to the left, and remove the jack.
9. Finish tightening the lug nuts. Push
down on the wrench while tightening
for increased leverage. Alternate nuts
until each nut has been tightened
twice. The correct wheel nut tightness
is 95 ft lbs (130 N·m). If in doubt about
the correct tightness, have them
checked with a torque wrench by your
authorized dealer or at a service
station.
10. Remove the jack assembly and wheel
blocks.
11. Secure the tire, jack, and tools in their
proper locations.
12. Remove blocks from wheels.
