cap, if the vehicle has one, to reach
the wheel bolts.1. Do a safety check before proceeding. See If a Tire Goes
Flat 0273.
2. Turn the wheel wrench counterclockwise to loosen and
remove the wheel nut caps.
Do not try to remove plastic
caps from the cover or
center cap. 3. Pull the cover or center cap
away from the wheel. Store the
wheel cover in the cargo area
until you have the flat tire
repaired or replaced.
4. Turn the wheel wrench
counterclockwise to loosen all
the wheel nuts, but do not
remove them yet.
5. Place the jack near the flat tire.
6. Put the compact spare tire near you.
{Warning
Getting under a vehicle when it is
lifted on a jack is dangerous.
If the vehicle slips off the jack,
you could be badly injured or
killed. Never get under a vehicle
when it is supported only by
a jack.
{Warning
Raising the vehicle with the jack
improperly positioned can
damage the vehicle and even
make the vehicle fall. To help
avoid personal injury and vehicle
damage, be sure to fit the jack lift
head into the proper location
before raising the vehicle.

{Warning
Lifting a vehicle and getting under
it to do maintenance or repairs is
dangerous without the
appropriate safety equipment and
training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could
be badly injured or killed if the
vehicle slips off the jack. If a jack
is provided with the vehicle, only
use it for changing a flat tire.
7. Attach the jack lift assist tool to the jack by fitting both ends of
the jack and tool over one
another.
8. Place the jack under the vehicle.
Caution
Make sure that the jack lift head
is in the correct position or you
may damage your vehicle. The
repairs would not be covered by
your warranty.
9. Position the jack lift head at thejack location nearest the flat
tire. The location is indicated
by a mark near the bottom
edge of the lower molding. The
jack must not be used in any
other position.
10. Raise the vehicle by turning the jack handle clockwise. Raise
the vehicle far enough off the
ground so there is enough
room for the road tire to clear
the ground.

11. Remove all of the wheel nuts.
12. Remove the flat tire.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
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(Continued)
Warning (Continued)
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
13. Remove any rust or dirt fromthe wheel bolts, mounting
surfaces, and spare wheel.
14. Place the compact spare tire on the wheel-mounting surface.
{Warning
Never use oil or grease on bolts

could fall off, causing a crash.
15. Reinstall the wheel nuts. Tighten each nut by hand until
the wheel is held against
the hub.
16. Lower the vehicle by turning the jack handle
counterclockwise.
{Warning
Wheel nuts that are improperly or

nuts. SeeCapacities and
Specifications 0319 for original
equipment wheel nut torque
specifications.
Caution
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
0 319 for the wheel nut torque
specification.
17. Tighten the wheel nuts firmly in a crisscross sequence, as
shown.
18. Lower the jack all the way and remove the jack from under the
vehicle.
19. Tighten the wheel nuts firmly with the wheel wrench.

center cap on the full-size tire,
tighten all five plastic caps hand
snug, then tighten them with the
wheel wrench an additional
one-quarter turn.
Caution
Wheel covers will not fit on the
vehicle's compact spare. If you try
to put a wheel cover on the
compact spare, the cover or the
spare could be damaged.
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.

4. Replace the foam, jack and tools, and the tire.
5. Turn the retainer nut clockwise to secure the tire.
6. Place the floor cover on the wheel.
To store the compact spare tire, use
the shorter mounting bolt. The compact spare is for temporary
use only. Replace the compact
spare tire with a full-size tire as
soon as you can.
Compact Spare Tire
{Warning
Driving with more than one
compact spare tire at a time could
result in loss of braking and
handling. This could lead to a
crash and you or others could be
injured. Use only one compact
spare tire at a time.
If this vehicle has a compact spare
tire, it was fully inflated when new;
however, it can lose air over time.
Check the inflation pressure
regularly. It should be 420 kPa
(60 psi).
Stop as soon as possible and check
that the spare tire is correctly
inflated after being installed on the
vehicle. The compact spare tire is
designed for temporary use only.
The vehicle will perform differently with the spare tire installed and it is
recommended that the vehicle
speed be limited to 80 km/h
(50 mph). To conserve the tread of
the spare tire, have the standard tire
repaired or replaced as soon as
convenient and return the spare tire
to the storage area.
When using a compact spare tire,
the AWD (if equipped), ABS, and
Traction Control systems may
engage until the spare tire is
recognized by the vehicle,
especially on slippery roads. Adjust
driving to reduce possible
wheel slip.
Caution
When the compact spare is
installed, do not take the vehicle
through an automatic car wash
with guide rails. The compact
spare can get caught on the rails
which can damage the tire, wheel,
and other parts of the vehicle.
Do not use the compact spare on
other vehicles.

5. Connect the other end of thepositive (+) cable to the
positive (+) terminal of the
good battery. Use a remote
positive (+) terminal if the
vehicle has one.
6. Connect one end of the black negative (−) cable to the
negative (−) terminal of the
good battery.
7. Connect the other end of the negative (−) cable to the
negative (–) grounding point for
the discharged battery.
8. Start the vehicle with the good battery and run the engine at
idle speed for at least
four minutes.
9. Try to start the vehicle that had the dead battery. If it will not
start after a few tries, it
probably needs service.Caution
If the jumper cables are
connected or removed in the
wrong order, electrical shorting
may occur and damage the
vehicle. The repairs would not be
covered by the vehicle warranty.
Always connect and remove the
jumper cables in the correct order,
making sure that the cables do
not touch each other or other
metal.
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
Towing the Vehicle
Caution
Incorrectly towing a disabled
vehicle may cause damage. The
damage would not be covered by
the vehicle warranty.
Do not lash or hook to
suspension components. Use the
proper straps around the tires to
secure the vehicle.
Have the vehicle towed on a wheel
lift tow truck. A flatbed car carrier
could damage the vehicle. The
wheel lift tow truck must raise the
rear of the vehicle and wheel dollies
must be used to lift the front wheels
off the ground.
Consult your dealer or a
professional towing service if the
disabled vehicle must be towed.

Hoses
Hoses transport fluids and should
be regularly inspected to ensure
that there are no cracks or leaks.
With a multi-point inspection, your
dealer can inspect the hoses and
advise if replacement is needed.
Lamps
Properly working headlamps,
taillamps, and brake lamps are
important to see and be seen on
the road.
.Signs that the headlamps need
attention include dimming, failure
to light, cracking, or damage.
The brake lamps need to be
checked periodically to ensure
that they light when braking.
. With a multi-point inspection,
your dealer can check the lamps
and note any concerns. Shocks and Struts
Shocks and struts help aid in control
for a smoother ride.
.
Signs of wear may include
steering wheel vibration, bounce/
sway while braking, longer
stopping distance, or uneven
tire wear.
. As part of the multi-point
inspection, trained dealer
technicians can visually inspect
the shocks and struts for signs
of leaking, blown seals,
or damage, and can advise
when service is needed. Tires

rotated, and balanced. Maintaining
the tires can save money and fuel,
and can reduce the risk of tire
failure.
