Removing the Flat Tire and
Installing the Spare Tire
This vehicle may have aluminum
wheels with exposed wheel nuts.
Use the wheel wrench to loosen all
the wheel nuts. Do not remove
them yet.
Or, this vehicle may have steel
wheels with plastic covers.
To remove the plastic covers and
wheel nut caps, loosen the plastic
nut caps with the wheel wrench in a
counterclockwise direction.If needed, finish loosening them
with your fingers. The plastic nut
caps will not come off.
If needed, use the flat end of the
wheel wrench and pry along the
edge of the cover until it comes off.
The edge of the wheel cover could
be sharp, so do not try to remove it
with your bare hands. Do not drop
the cover or lay it face down, as it
could become scratched or
damaged. Store the wheel cover in
the trunk until the flat tire is repaired
or replaced.
Once you have removed the wheel
cover, use the following procedure
to remove the flat tire and install the
spare tire.
1. Do a safety check before
proceeding. See If a Tire Goes
Flat on page 10‑54.
2. Turn the wheel wrench counterclockwise once on each
wheel nut to loosen it. Do not
remove them yet.

off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
7. Remove any rust or dirt from thewheel bolts, mounting surfaces,
and spare wheel. 8. Install the compact spare tire.
{WARNING
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel

9. Reinstall the wheel nuts with the
rounded end of the nuts toward
the wheel. Tighten each nut
clockwise by hand until the
wheel is held against the hub.

10. Lower the vehicle byturning the jack handle
counterclockwise. Lower the
jack completely.
{WARNING
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See Capacities and
Specifications on page 12‑2 for
original equipment wheel nut
torque specifications. Notice:
Improperly tightened
wheel nuts can lead to brake
pulsation and rotor damage. To
avoid expensive brake repairs,
evenly tighten the wheel nuts in
the proper sequence and to the
proper torque specification. See
Capacities and Specifications on
page 12‑2 for the wheel nut
torque specification.
11. Tighten the wheel nuts firmly in a crisscross sequence as
shown.

Jump Starting
For more information about the
vehicle battery, seeBattery on
page 10‑21.
If the battery has run down, try to
use another vehicle and some
jumper cables to start your vehicle.
Be sure to use the following steps to
do it safely.
{WARNING
Batteries can hurt you. They can
be dangerous because:
.They contain acid that can
burn you.
.They contain gas that can
explode or ignite.
.They contain enough
electricity to burn you.
If you do not follow these steps
exactly, some or all of these
things can hurt you. Notice:
Ignoring these steps
could result in costly damage to
the vehicle that would not be
covered by the warranty.
Trying to start the vehicle by
pushing or pulling it will not
work, and it could damage the
vehicle.
The jump start positive is located in
the engine compartment under the
engine compartment fuse block
cover on the passenger side of the
vehicle.
The jump start negative grounding
point is the engine block or an
engine mounting bolt. Connect to a
spot as far away from the
discharged battery as possible.
These locations are used instead of
a direct connection to the battery.
1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system. Notice:
Only use a vehicle that
has a 12-volt system with a
negative ground for jump
starting. If the other vehicle does
not have a 12-volt system with a
negative ground, both vehicles
can be damaged.
2. Position the two vehicles so that they are not touching.
3. Set the parking brake firmly and put the shift lever in P (Park).
See Shifting Into Park on
page 9‑21.
Notice: If the radio or other
accessories are left on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
4. Turn the ignition to LOCK/OFF and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.

ensure that the front wheels are
locked into the straight position.
6. Secure the vehicle to the dolly following the manufacturer's
instructions.
7. Release the parking brake only after the vehicle being towed is
firmly attached to the towing
vehicle.
8. Turn the ignition to LOCK/OFF and remove the key.Appearance Care
Exterior Care
Washing the Vehicle
To preserve the vehicle's finish,
wash it often and out of direct
sunlight.
Notice: Do not use petroleum
based, acidic, or abrasive
cleaning agents as they can
damage the vehicle's paint, metal,
or plastic parts. If damage
occurs, it would not be covered
by the vehicle's warranty.
Approved cleaning products can
be obtained from your dealer.
Follow all manufacturer
directions regarding correct
product usage, necessary safety
precautions, and appropriate
disposal of any vehicle care
product. Notice:
Avoid using high
pressure washes closer than
30 cm (12 in) to the surface of the
vehicle. Use of power washers
exceeding 8,274 kPa (1,200 psi)
can result in damage or removal
of paint and decals.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.

Vehicle Care 10-71
Tires
Use a stiff brush with tire cleaner to
clean the tires.
Notice:Using petroleum-based
tire dressing products on the
vehicle may damage the paint
finish and/or tires. When applying
a tire dressing, always wipe off
any overspray from all painted
surfaces on the vehicle.
Wheels and Trim —Aluminum
or Chrome
Use a soft, clean cloth with mild
soap and water to clean the wheels.
After rinsing thoroughly with clean
water, dry with a soft, clean towel.
A wax may then be applied.
Keep the wheels clean using a soft,
clean cloth with mild soap and
water. Rinse with clean water. After
rinsing thoroughly, dry with a soft,
clean towel. A wax may then be
applied. Notice:
Chrome wheels and other
chrome trim may be damaged if
the vehicle is not washed after
driving on roads that have been
sprayed with magnesium,
calcium, or sodium chloride.
These chlorides are used on
roads for conditions such as ice
and dust. Always wash the
chrome with soap and water after
exposure.
Notice: To avoid surface damage,
do not use strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum or
chrome-plated wheels. Use only
approved cleaners. Also, never
drive a vehicle with aluminum or
chrome-plated wheels through an
automatic car wash that uses
silicone carbide tire cleaning
brushes. Damage could occur
and the repairs would not be
covered by the vehicle warranty.
Steering, Suspension, and
Chassis Components
Visually inspect front and rear
suspension and steering system for
damaged, loose, or missing parts or
signs of wear. Inspect power
steering lines and hoses for proper
hook-up, binding, leaks, cracks,
chafing, etc. Visually check constant
velocity joints, rubber boots, and
axle seals for leaks.
Body Component Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges, and the
steel fuel door hinge unless the
components are plastic. Applying
silicone grease on weatherstrips
with a clean cloth will make them
last longer, seal better, and not stick
or squeak.
