Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place, well off the road,
if possible. Turn on the hazard warning flashers. See
Hazard Warning Flashers on page 4‑3.
{WARNING:
Changing a tire can be dangerous. The vehicle
can slip off the jack and roll over or fall on you or
other people. You and they could be badly injured
or even killed. Find a level place to change your
tire. To help prevent the vehicle from moving:1. Set the parking brake firmly.
2. Put the shift lever in P (Park).
3. Turn off the engine and do not restart while the vehicle is raised.
4. Do not allow passengers to remain in the vehicle.
To be even more certain the vehicle will not move,
you should put blocks at the front and rear of the
tire farthest away from the one being changed.
That would be the tire, on the other side, at the
opposite end of the vehicle. When the vehicle has a flat tire (B), use the following
example as a guide to assist you in the placement of
wheel blocks (A).
A. Wheel Block
B. Flat Tire
The following information explains how to use the jack
and change a tire.

wrench to gently pry the wheel covers off. Store
the wheel cover and lug nut caps in the trunk
until you have the flat tire repaired or replaced. Be careful not to scratch the aluminum wheel edge

4. Find the jacking location from the diagram aboveand use the corresponding cutouts located in the
plastic molding.
The front location is (A) 8.5 inches (21 cm) from
the rear edge of the front wheel well, and the rear
location (B) is 3.5 inches (8.5 cm) from the front
edge of the rear wheel well.
The notches may also be labeled JACK with an
arrow pointing to the jacking location on the
vehicle.
{WARNING:
Getting under a vehicle when it is jacked up 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 your 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.
Notice: If you position the jack under the rocker
molding and attempt to raise the vehicle, you could
break the molding and/or cause other damage to
your vehicle. Always position the jack so that when
the jack head is raised, it will fit firmly in the notch
located inboard from the rocker molding.
5. Turn the jack handle counterclockwise to lower the jack lift head until the jack fits under the vehicle.

10. Remove any rust or dirtfrom the wheel bolts,
mounting surfaces, and
spare wheel.
{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, use a cloth or
a paper towel to do this; but be sure to use a
scraper or wire brush later, if needed, to get all
the rust or dirt off. See Changing a Flat Tire
on
page 6‑83
. 11. Place the spare tire on the wheel-mounting
surface.
{WARNING:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle's wheel
could fall off, causing a crash.
12. Put the wheel nuts back on with the
rounded end of the
nuts toward the wheel.
Tighten each nut by
hand until the wheel is
held against the hub.

{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 6‑112
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 6‑112for the wheel nut
torque specification.
