Tire Change Procedure
WARNINGS
When one of the front wheels is off the
ground, the transmission alone will not
prevent the vehicle from moving or slipping
off the jack. To help prevent the vehicle from
moving when you change a tire, be
sure to place the transmission in park (P), set
the parking brake and block (in both
directions) the wheel that is diagonally
opposite (other side and end of the vehicle)
to the tire being changed. Never get underneath a vehicle that is
supported only by a jack. If the vehicle
slips off the jack, you or someone else could
be seriously injured. 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. WARNINGS
Always use the jack provided as
original equipment with your vehicle.
If using a jack other than the one provided
as original equipment with your vehicle,
make sure the jack capacity is adequate for
the vehicle weight, including any vehicle
cargo or modifications. Disable the power running boards
before jacking, lifting, or placing any
object under the vehicle. Never place your
hand between the power running board and
the vehicle as extended power running
boards will retract when the doors are
closed. Failure to follow these instructions
may result in personal injury. Failure to follow these instructions
when using the spare tire carrier could
cause loss of the wheel and tire and lead to
personal injury: Only use the spare tire carrier
to stow the tire and wheel combination
specified on the Tire Label or Safety
Compliance Certification Label on the B-Pillar
or the edge of the driver door. Other tire and
wheel combinations could cause the carrier
to fail if it does not fit securely or is too
heavy. Do not use impact tools or power WARNINGS
tools operating over 200 RPM, which may
cause winch malfunction and prevent a
secure fit. Override the winch at least three
times (there will be an audible click each
time) to ensure a tight secure fit of the wheel
and tire. Note:
Passengers should not remain in the
vehicle when the vehicle is being jacked.
Park on a level surface, activate the hazard
flashers and set the parking brake. Then,
place the transmission in park (P) and turn
the engine off.
Removing the Jack and Tools
Note: Pay close attention to the orientation
of the bag, because it will have to be
reinstalled after changing the tire.
1. Open the liftgate, then locate the access
panel on the floor behind the third row
seat. Unlatch and remove the panel.

Rear jacking point 1. With the vehicle on level ground, block
both sides of the wheel diagonally
opposite (other side and end of the
vehicle) to the wheel being changed. Do
not jack the vehicle on a hill or incline.
2. Obtain the spare tire and jack tools from
their storage locations.
3. Use the tip of the jack handle to remove
any wheel trim.
4. Loosen each wheel lug nut one-half turn
counterclockwise but do not remove
them until the wheel is raised off the
ground.
5. Position the jack according to the jack locator arrows found on the frame and
turn the jack handle and extension tool
assembly clockwise.
6. Raise the vehicle to provide sufficient ground clearance when installing the
spare tire, about 1/4 inch (6 millimeters).
7. Remove the lug nuts with the lug wrench. Installing the Spare Tire
1. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward.
2. 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.
3. Lower the wheel by turning the jack handle counterclockwise. 4.
Remove the jack and fully tighten the lug
nuts in the order shown. See Technical
Specifications (page 326).
