If a Tire Goes Flat
10. Then replace the pressure cap. At any time during
this procedure
if coolant begins to flow out of the
filler neck, reinstall the pressure cap. Be sure the
arrows on the pressure cap line
up like this.
11. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine is cold. It’s
unusual for a tire
to “blow out” 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 “blowout,” 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.
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. Wrn 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.

Wheel Covers
To remove a center cap, use
the wrench to pry gently at
the notch. Don’t use a tool
that is narrower than the
wrench
to pry at this notch.
Then pry off the cap. If
your vehicle is equipped
with wheel covers, be sure
to use a wheel wrench to
begin the process
of
loosening the plastic wheel
nut caps.
They won’t come off. You will only be able to loosen
them. Once you have loosened the plastic nut caps with
the wheel wrench, if needed, you can finish loosening
them with your fingers.
Then, using the flat end
of the wheel wrench, pry along
the edge of the wheel cover until
it comes off. Be
careful; the edge may be sharp. Don’t try to remove the
cover with your bare hands.

A 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.

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.

spare tire. It won’t fit. Store the wheel cover in the
trunk until you have the flat tire repaired
or replaced.

Wheel covers won’t fit on your compact spare. If
you try to put a wheel cover on your compact
spare, you could damage the cover or the spare.

Storing the Flat Tire and Tools
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.
After you’ve put the compact spare tire on your vehicle,
you’ll need to store the flat tire in your trunk. Use the
following procedure to secure the flat tire
in the trunk.
When storing a full-size tire you must use the extension
with the protector/guide to help avoid wheel surface
damage. Use the extension and protector/guide located
in the foam holder.
To store a full-size tire, place the tire
valve stem facing down and then remove
the
protector/guide and attach the retainer securely. When reinstalling
a compact spare tire, put the
protector/guide back in the foam holder. Store the cover
as far forward as possible.
