Storing the Tools
To store the tools:1. Return the tools (wheel wrench, jack handle, and jack handle extensions) to
the tool bag. Use the velcro straps to
secure the tool bag under the load floor
in the cargo area.
2. Position the jack and wheel blocks in the driver side trim panel over the
wheelhouse.
3. Turn the jack knob clockwise until the jack is secured tight in the mounting
bracket. Be sure to position the holes in
the base of the jack onto the pin in the
mounting bracket.
4. Close the trim panel door.
Storing a Flat Tire Inside of the Vehicle
If the vehicle has 275/60R20 or 275/50R22
size tires, the flat tire must be stored inside
of the vehicle in the cargo area using the
flat tire secure strap inside the glove box. 1. Store the tools. See “Storing the Tools”
earlier in this section.
2. If the vehicle has a short wheel base, the third row seat must be folded down to
provide sufficient space to store the flat
tire. If the third row seat cannot be folded down, the flat tire cannot be
stored and must be left in a safe
location, to be picked up at a later time.
3. Once there is sufficient space in the rear of the vehicle, lift the flat tire and place
it on top of the load floor, with the
valve stem pointed up.4. Remove the flat tire secure strap from
the glove box and place the loop end of
the strap through the cargo tie-down.
Place the hook end of the strap through
the loop and pull it until the strap is
fastened securely to the tie-down.
5. Route the hook end of the strap throughthe wheel, as shown.
6. Attach the hook to the other cargo tie-down in the rear of the vehicle.
7. Tighten the strap.
Full-Size Spare Tire
If this vehicle came with a full-size spare
tire, it was fully inflated when new,
however, it can lose air over time. Check the
inflation pressure regularly. See Tire Pressure
0 346 and
Vehicle Load Limits 0222 for information
regarding proper tire inflation and loading
the vehicle. For instructions on how to
remove, install, or store a spare tire, see Tire
Changing 0358.

If equipped with a temporary use full-size
spare tire, it is indicated on the tire sidewall.
SeeTire Sidewall Labeling 0343. This spare
tire should not be driven on over 112 km/h
(70 mph), or 88 km/h (55 mph) when
pulling a trailer, at the proper inflation
pressure. Repair and replace the road tire as
soon as it is convenient, and stow the spare
tire for future use.
Caution
If the vehicle has four-wheel drive and a
different size spare tire is installed, do
not drive in four-wheel drive until the flat
tire is repaired and/or replaced. The
vehicle could be damaged and the repairs
would not be covered by the warranty.
Never use four-wheel drive when a
different size spare tire is installed on the
vehicle.
The vehicle may have a different size spare
tire than the road tires originally installed
on the vehicle. This spare tire was developed
for use on this vehicle, so it is all right to
drive on it. If the vehicle has four-wheel
drive and a different size spare tire is
installed, drive only in two-wheel drive. After installing the spare tire on the vehicle,
stop as soon as possible and check that the
spare is correctly inflated. The spare tire is
made to perform well at speeds up to
112 km/h (70 MPH) at the recommended
inflation pressure, so you can finish
your trip.
Have the damaged or flat road tire repaired
or replaced and installed back onto the
vehicle as soon as possible so the spare tire
will be available in case it is needed again.
Do not mix tires and wheels of difference
sizes, because they will not fit. Keep the
spare tire and its wheel together.
If the vehicle has a spare tire that does not
match the original road tires and wheels in
size and type, do not include the spare in
the tire rotation.
