.If a Tire Goes Flat Changing a Flat Tire
It’s unusual for a tire to “blow out” while you’re driving,
especially
if you maintain yourtires 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:
1
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, then gentlv
I. - 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 your tire goes flat, the next section shows how to use
your jacking equipment to change a flat tire safely.
If a tire goes flat, avoid further tire and wheel damage
by driving slowly
to a level place. Turn on your hazard
warning flashers.
A “-CAUTION:
I 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 K- Ay.
2. Put the shift lever in “P” (Park
3. Turn off the engine.
To be even more certain the vehicle won’t mob
you can put chocks at the front and rear of t
tire farthest away from the one being changed,
I That would be the tire on the oP?r side of the
vehicle, the oppos’-
1 end.
CAUTION: (Continued)

Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear the area around your front wheels. Then shift back
and forth between “R” and a forward gear
, spinning the
wheels as little as possible. Release the accelerator pedal
while you shift, and press lightly on the accelerator
pedal when the transaxle is in gear. If that doesn’t get
you out after a few tries, you may need
to be towed out.
If you do need to be towed out, see “Towing Your Car”
in the Index.

Fuses and Circuit Breakers
The wiring circuits in your car are protected from short
circuits.by a combination of fuses, circuit breakers, and
fusible thermal links in the wiring itself. This greatly
reduces the chance of fires caused by electrical
problems.
Be sure to use the correct fuse. If you ever have a
problem on the road and don’t have a spare fuse, you
I
can “borrow” one of the identical size and rating. Just
pick some feature of your car that you can get along
without
-- like the radio or cigarette lighter -- and use its
fuse, if it is of the value you need. Replace it as soon as
you can.
The fuse panel
is to the left of the steering column, near
the parking brake release lever. Pull the cover down to
access the fus.es.

or lack of lubrication. Inspect the
power steering lines and hoses for
proper hookup, binding, leaks, cracks, chafing, etc. Clean and then
inspect the drive axle boot seals for
damage, tears or leakage. Replace
seals
if necessary.
Inspect the complete exhaust system. Inspect the body near the
exhaust system. Look for broken,
damaged, missing or out-of-position
parts as well as open seams, holes,
loose connections,
or other
conditions which could cause a heat
build-up in the floor pan or could let
exhaust fumes into the vehicle. See

Inspect disc brake pads for wear
and rotors for swrface condition.
Also
inspect Qwn brake linings for wear and

brake is self-adjusting and no manual adjustment
is required. You may need
to have your brakes inspected more often
if your driving habits or
conditions result in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may
need to be serviced. Also, if the
brake system warning light stays on or
comes on, something may
be wrong
with the brake system. See “Brake System
Warning Light” in the Index. If
your anti-lock brake system warning
light stays
on, comes on or flashes,
something may
be wrong with the
anti-lock brake system. See “Anti-Lock
