Mounting Spare Tire
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts fully until the
vehicle has been lowered. Failure to follow
this warning may result in personal injury.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. Finish tightening the lug nuts. Push down
on the wrench while at the end of the handle for
increased leverage. Tighten the lug nuts in a
star pattern until each nut has been tightened
twice. The correct wheel nut tightness is 110
ft-lbs (150 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.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.
12. Remove the small center cap and securely
store the road wheel in the cargo area.
