Storing a Flat or Spare Tire and Tools
{Warning
Storing a jack, a tire, or other equipment
in the passenger compartment of the
vehicle could cause injury. In a sudden
stop or collision, loose equipment could
strike someone. Store all these in the
proper place.
{Warning
Failure to follow these tire storage
instructions carefully could result in
personal injury or property damage if the
hoist cable fails or if the tire comes loose.
Make sure the tire is stored securely
before driving.
Caution
Always store the spare tire or flat tire
with the valve stem pointed up. Stowing
a tire with the valve stem pointed down
could result in damage to the wheel.
Caution
The tire hoist is designed to be raised
and lowered with tension on the cable.
If the hoist must be raised or lowered
without a tire attached, do so only by
hand, and at a slow pace, to avoid
damaging the mechanism. Do not use
power tools.
{Warning
An improperly stored spare tire could
come loose and cause a crash. To avoid
personal injury or property damage,
always store the spare tire when the
vehicle is parked on a level surface.If the vehicle has 275/60R20 or 275/50R22
size tires, the flat tire must be stored inside
of the vehicle using the flat tire secure strap
inside the glove box. See
“Storing a Flat Tire
Inside of the Vehicle” later in this section.
If the vehicle has 265/65R18 or 275/55R20
size tires, store the flat tire under the rear
of the vehicle in the spare tire carrier. Refer
to the following graphics and instructions:

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.

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 0194 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 0360. 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 different
sizes, because they will not fit. Keep the
spare tire and its wheel together.
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.
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.
If equipped with a temporary use full-size
spare tire, it is indicated on the tire sidewall.
See
Tire Sidewall Labeling 0342. 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.
Jump Starting
Jump Starting - North America
For more information about the vehicle
battery, see Battery - North America 0326.
If the vehicle's battery (or batteries) has run
down, you may want to use another vehicle
and some jumper cables to start your
vehicle. Be sure to use the following steps
to do it safely.

Warning (Continued)
Battery fluid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on
your skin, flush the place with water and
get medical help immediately.
{Warning
Fans or other moving engine parts can
injure you badly. Keep your hands away
from moving parts once the engine is
running.
6. Check that the jumper cables do not have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged too.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) or to a
remote positive (+) terminal if the
vehicle has one. Negative (−) will go to a
heavy, unpainted metal engine part or to
a remote negative (−) terminal if the
vehicle has one. Do not connect positive (+) to negative
(−) or you will get a short that would
damage the battery and maybe other
parts too. And do not connect the
negative (−) cable to the negative (−)
terminal on the dead battery because
this can cause sparks.
7. Connect one end of the red positive (+) cable to the discharged battery
positive (+) terminal.
8. Do not let the other end touch metal. Connect it to the good battery
positive (+) terminal. Use a remote
positive (+) terminal if the vehicle
has one.
9. Connect one end of the black negative (−) cable to the good battery negative
(−) terminal. Use a remote negative (−)
terminal if the vehicle has one.
Do not let the other end touch anything
until the next step.
10. Connect the other end of the negative (−) cable to the discharged battery
negative (−) grounding point.
11. Start the vehicle with the good battery and run the engine for a while. 12. Try to start the vehicle that had the
dead battery. If it will not start after a
few tries, it probably needs service.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it to idle
for several minutes.Towing the Vehicle
Transporting a Disabled Vehicle
