WARNING: To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel. WARNING:
Do not get under a
vehicle that is supported by a jack. WARNING:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough
off the road to avoid the danger of being
hit when operating the jack or changing
the wheel.
Note: Passengers should not remain in the
vehicle when the vehicle is being jacked.
Park on a level surface, set the parking
brake and activate the hazard flashers. 1.
Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using a wheel chock. 2. Loosen each wheel lug nut ½ turn
counterclockwise, but do not remove
them until the wheel is raised off the
ground.
3. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front and inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.
4. Lower the wheel and fully tighten the lug nuts in the order shown below. See
Technical Specifications (page 279).
5. Unblock the wheels. 8-lug nut torque sequence.
10-lug nut torque sequence.
