6. Raise the vehicle by turning the
jack screw clockwise. Raise the
vehicle only until the tire just
clears the surface and enough

8. Position the spare wheel/tire on
the vehicle and install the lug

blocks.
10. Finish tightening the lug nuts.
Push down on the wrench while

each nut has been tightened

If in doubt about the correct
tightness, have them checked
with a torque wrench by your
authorized dealer or at a service
station.

the proper positions in the foam tray.
12. Remove the small center cap and securely store the road wheel in the

possible, properly secure the
spare tire with the special wing
nut torqued to 3.7 ft-lbs (5 N·m),
reinstall the jack and tool kit
foam tray, and latch the rear load
