CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Note:If your vehicle is equipped with the tire pressure monitoring
system (TPMS), the indicator light will illuminate when the spare tire is
in use. To restore the full functionality of the monitoring system, all road
wheels equipped with tire pressure monitoring sensors must be mounted
on the vehicle.
If your vehicle is equipped with TPMS, have a flat serviced by an
authorized dealer in order to prevent damage to the TPMS sensors, refer
toTire pressure monitoring system (TPMS)in theTires, Wheels and
Loadingchapter. Replace the spare tire with a road tire as soon as
possible. During repairing or replacing of the flat tire, have the
authorized dealer inspect the TPMS sensor for damage.

2. Remove the spare tire and jack from the storage location.
•The jack is located in the rear
right-hand side of the cargo area.
3. Remove any wheel trim. Insert the tapered end of the lug nut wrench
behind wheel covers or hubcaps and twist off.
4. Loosen the wheel nut by pulling up on the handle of the lug nut
wrench about one-half turn (counterclockwise). Do not remove the
wheel lug nuts until you raise the tire off the ground.
WARNING:When one of the rear wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the transmission is in P (Park).
Replacing the tire
1. Assemble the jack handle sections together and lock into the jack. Use
the jack handle to slide the jack under the vehicle.
WARNING:To lessen the risk of personal injury, do not put any
part of your body under the vehicle while changing a tire. Do not
start the engine when your vehicle is on the jack. The jack is only
meant for changing the tire.

WARNING:When a wheel is installed, always remove any
corrosion, dirt or foreign materials present on the mounting
surfaces of the wheel or the surface of the wheel hub, brake drum or
brake disc that contacts the wheel. Ensure that any fasteners that
attach the rotor to the hub are secured so they do not interfere with
the mounting surfaces of the wheel. Installing wheels without correct
metal-to-metal contact at the wheel mounting surfaces can cause the
wheel nuts to loosen and the wheel to come off while the vehicle is in
motion, resulting in loss of control.
Note:Inspect the wheel pilot hole
prior to installation. If there is
visible corrosion in wheel pilot hole,
remove loose particles by wiping
with clean rag and apply grease.
Apply grease only to the wheel pilot
hole surface by smearing a “dime”
(1 square cm) sized glob of grease
around the wheel pilot surface (1)
with end of finger. DO NOT apply
grease to lugnut/stud holes or
wheel-to-brake surfaces.
JUMP STARTING
WARNING:The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.

Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may have firm and/or soft shifts. This operation is
considered normal and will not affect function or durability of the
transmission. Over time, the adaptive learning process will fully update
transmission operation.
1.Use only a 12–volt supply to start your vehicle.
2. Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
3. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehiclesdo nottouch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
4. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
5. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.

1. Connect the positive (+) jumper
cable to the positive (+) terminal of
the discharged battery.
2. Connect the other end of the
positive (+) cable to the positive
(+) terminal of the assisting battery.
3. Connect the negative (-) cable to
the negative (-) terminal of the
assisting battery.
4. Make the final connection of the
negative (-) cable to an exposed
metal part of the stalled vehicle’s
engine, away from the battery and
the carburetor/fuel injection system.
Note:Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
WARNING:Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
Ensure that the cables are clear of fan blades, belts, moving parts of both
engines, or any fuel delivery system parts.
Jump starting
1. Start the engine of the booster vehicle and run the engine at
moderately increased speed.
2. Start the engine of the disabled vehicle.
3. Once the disabled vehicle has been started, run both engines for an
additional three minutes before disconnecting the jumper cables.
