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.
Tire change procedure
Preparing to change the tire
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park).

4. Apply the parking brake and turn
engine OFF.
5. Block the wheel that is diagonally
opposite the tire you are changing.
The parking brake is on the
transmission. Therefore, the vehicle
will not be prevented from moving
when a rear wheel is lifted, even if
the parking brake is applied. Be
sure to block both directions of the wheel that is diagonally opposite to
the wheel that is being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.
6. Remove the spare tire and jack from the storage location.
7. 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.
Replacing the tire
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.
8. Position the jack to raise the front or rear wheel.
Roadside emergencies

Batteries contain sulfuric acid which can burn skin, eyes, and
clothing, if contacted.
Do not attempt to push-start your vehicle. Automatic
transmissions do not have push-start capability; also, the
catalytic conveter may become damaged.
Preparing your vehicle
When the battery is disconnected or a new battery is installed, the
transmission must relearn its adaptive strategy. As a result of this, the
transmission may shift firmly. 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 to its
optimum shift feel.
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 any electrical
surges. Turn all other accessories off.
Connecting the jumper cables
1. Connect the positive (+) booster cable to the positive (+) terminal of
the discharged 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.Do notuse fuel lines, engine rocker
covers or the intake manifold asgroundingpoints.
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.
5. 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.

3. Remove the jumper cable from the positive (+) terminal of the booster
vehicle’s battery.
4. Remove the jumper cable from the positive (+) terminal of the
disabled vehicle’s battery.
After the disabled vehicle has been started and the jumper cables
removed, allow it to idle for several minutes so the engine computer can
relearnits idle conditions.
WRECKER TOWING
If you need to have your vehicle towed, contact a professional towing
service or, if you are a member, your roadside assistance center.
It is recommended that your vehicle be towed with a wheel lift or flatbed
equipment.
If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
When calling for a tow truck, tell the operator what kind of vehicle you
have.

CLEANING THE WHEELS
Wash with the same detergent as the body of your vehicle. Do not use
acid-based or alcohol-based wheel cleaners, steel wool, fuel or strong
detergents. Never use abrasives that will damage the finish of special
wheel surfaces. Use a tar remover to remove grease and tar.
The brushes used in some automatic car washes may damage the finish
on your wheels. Before going to a car wash, find out if the brushes are
abrasive.
CLEANING THE ENGINE
Engines are more efficient when they are clean because grease and dirt
buildup keep the engine warmer than normal. When washing:
•The engine must be cool to the touch before spraying with water.
•Never spray a hot engine with cold water, as damage to the
engine block or engine components may occur.
•Use caution when using a self-serve power washer (1000psi maximum
pressure) to clean the engine, as the high-pressure fluid could
penetrate the sealed parts and cause damage.
•Never apply anything to any exposed belts in the engine
compartment, including the belt dressing.
For general cleaning of the engine and engine compartment, spray
Engine Shampoo and Degreaser (F4AZ-19A536–A) on all parts that
require cleaning and pressure rinse the area with cool water.
•Never wash or rinse the engine while it is running; water in the
running engine may cause internal damage.
UNDERBODY
Flush the complete underside of vehicle frequently. Keep body drain
holes unplugged. Inspect for road damage.
