vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire.

the lug nuts toward the wheel. Hand tighten the lug
nuts with vehicle lifted. To avoid the risk of forcing the
vehicle off the jack, do not fully tighten the lug nuts until
the vehicle has been lowered.
6. Lower vehicle to ground, 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. For the
correct lug nut torque refer to “Torque Specifications” in
“Technical Specifications”. If in doubt about the correct
tightness, have them checked with a torque wrench by
an authorized dealer or service station.

hard stop, could endanger the occupants of the vehicle.

9. Adjust the tire pressure when possible.
NOTE: Do not oil wheel studs. For chrome wheels, do not
substitute with chrome plated wheel nuts.

NOTE: Vehicles equipped with aluminum wheels cannot
be stored under the vehicle because the wheel retainer will
not fit through the wheel pilot hole. Secure the flat tire in
the bed of the truck. Have the flat tire repaired or replaced
immediately.
