Tightening Wheel Nut
Tightening Sequence
Use the wrench to tighten the wheel nuts firmly in a criss-cross sequence as
shown. Remove the wheel blocks.
Storing The Tire in The Underbody Carrier
Put the tire on the ground at the rear of the vehicle, with the valve stem
pointed down and to the rear.
Pull the retaining bar through the wheel.
NOTE: With ZR2 option, spring and retainer must be separated to insert
through wheel opening.
Put the chisel end of the wheel wrench, on an angle, through the hole in the
rear bumper and into the hoist shaft. Turn the wheel wrench right until the
tire is raised against the underside of the vehicle.
You will hear two"c1icks" when the tire is secure, but pull on the tire to
make sure.
