If a Tire Goes Flat
It's unusual for a tire to ªblow outº while you're driving,
especially if you maintain your tires properly. If air goes
out of a tire, it's much more likely to leak out slowly.
But if you should ever have a ªblowout,º here are a few
tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that
pulls the vehicle toward that side. Take your foot off the
accelerator pedal and grip the steering wheel firmly.
Steer to maintain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a
skid and may require the same correction you'd use in a
skid. In any rear blowout, remove your foot from the
accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be
very bumpy and noisy, but you can still steer. Gently
brake to a stop
-- well off the road if possible.
If a tire goes flat, the next part shows how to use your
jacking equipment to change a flat tire safely.

Changing a Flat Tire
If a tire goes flat, avoid further tire and wheel damage
by driving slowly to a level place. Turn on your hazard
warning flashers.
CAUTION:
Changing a tire can cause an injury. The vehicle
can slip off the jack and roll over you or other
people. You and they could be badly injured.
Find a level place to change your tire. To help
prevent the vehicle from moving:
1. Put the shift lever in PARK (P).
2. Set the parking brake firmly.
3. Turn off the engine.
To be even more certain the vehicle won't move,
you can 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 of the
vehicle, at the opposite end.
The following steps will tell you how to use the jack and
change a tire.

The equipment you'll need is in the trunk. On the
driver's side of the trunk is the spare tire. Pull the
fasteners on the spare tire cover to access the tire.

the trunk.

The tools you'll be using include the jack (A), the wheel
wrench (B) and the screwdriver (C).
Removing the Flat Tire and Installing the
Spare Tire
1. Use the flat end of the screwdriver to pry off the five
black plastic wheel bolt caps. Be careful not to
scratch the wheel edge.

2. Using the wheel wrench, loosen all of the wheel
bolts. Don't remove them yet.
3. Turn the jack handle clockwise to raise the jack lift
head 2 to 3 inches (5 to 7.6 cm).4. To access the jack hoisting notches, pull hard from
the back of the hoisting notch cover (located either in
front of or behind the tire you are changing).

5. Position the jack under the vehicle.The base of the jack must line up vertically with the
hoisting notch (jack contact point) on the vehicle's
frame, nearest the flat tire. Make sure that the base is
flat against the ground in order to have enough
clearance to turn the jack handle. Then, raise the jack
lift head until it is firmly set into the hoisting notch.

CAUTION:
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.
CAUTION:
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.6. Raise the vehicle by turning the jack handle
clockwise. Raise the vehicle far enough off the
ground for the spare tire to fit under the vehicle.
7. Remove all wheel bolts and take off the flat tire.
