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. Set the parking brake firmly.
2. Put the shift lever in PARK (P).
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.

5-23 Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to loosen the wheel nuts, but
don't remove them yet.
2. The jack has a bolt at the end. Attach the wheel
wrench to the bolt to create a jack handle.
3. Turn the wheel wrench counterclockwise to lower
the jack head until it fits under the vehicle.

5-25
5. Raise the vehicle by turning the wheel wrench
clockwise in the jack. Raise the vehicle far enough
so there's enough room for the spare tire to fit under
the wheel well.
6. Remove all the wheel nuts and take off the flat tire.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.

5-26
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
8. Place the compact spare tire on the
wheel
-mounting surface.
9. Reinstall the wheel nuts
with the rounded end of
the nuts toward the
wheel. Make sure each
wheel stud is centered in
each wheel hole while
tightening the nuts.
Tighten each nut by
hand until the wheel is
held against the hub.10. Lower the vehicle by turning the wheel wrench
counterclockwise on the jack. Lower the
jack completely.
11. Tighten the wheel
nuts firmly in a
crisscross sequence.

Filling Your Tank
CAUTION:
Gasoline vapor is highly flammable. It burns
violently, and that can cause very bad injuries.
Don't smoke if you're near gasoline or refueling
your vehicle. Keep sparks, flames and smoking
materials away from gasoline.
The fuel cap is located behind a hinged fuel door on the
driver's side of the vehicle.
While refueling, hang the tethered fuel cap from the
hook on the fuel door.
To remove the fuel cap, turn it slowly to the left
(counterclockwise). The fuel cap has a spring in it;
if you let go of the cap too soon, it will spring back
to the right.

6-7
CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel cap too quickly. This spray can happen if
your tank is nearly full, and is more likely in hot
weather. Open the fuel cap slowly and wait for
any ªhissº noise to stop. Then unscrew the cap
all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See ªCleaning
the Outside of Your Vehicleº in the Index.
When you put the fuel cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See ªMalfunction Indicator Lampº in
the Index.The GAS CAP LOOSE
-CHECK CAP message will
be displayed on the Driver Information Center (DIC)
(if equipped) if the fuel cap is not properly reinstalled.
NOTICE:
If you need a new fuel cap, be sure to get the
right type. Your dealer can get one for you. If you
get the wrong type, it may not fit properly. This
may cause your malfunction indicator lamp to
light and may damage your fuel tank and
emissions system. See ªMalfunction Indicator
Lampº in the Index.

Passenger Compartment Air Filter
(If Equipped)
If your vehicle has this feature, the outside air entering
the vehicle is routed through a filter. The filter removes
certain particles from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
often in dusty areas, indicate that the filter may need
to be replaced early.
The filter should be replaced as part of the routine
scheduled maintenance. See ªMaintenance Scheduleº
in the Index for more information.
The passenger compartment
air filter is located on the
passenger side at the base
of the windshield and
can be accessed through
a removable panel under
the hood of the vehicle.To check or replace the air filter:
1. With the hood open, unlatch and remove the
access panel.
2. To remove the filter, press on the spring tab on
the side of the filter housing and pull the filter out
of the housing.
3. To install the new filter, press on the spring tab and
insert the filter into the housing. The filter should be
fully inserted into the upper and lower grooves and
locked into place by the spring tab.
4. Reinstall the air filter access panel at the base of
the windshield.
