If a Tire Goes Flat
It’s Llnusual 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
f-bot 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 conxxtion 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
YOLI 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.
c
A 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.
The following steps
will tell you how to use the jack and
change
a tire.

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 towe
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.

passenger compartment of the vehicle could
cause in.jury. In a sudden stop
or collision, loose

be stored under the vehicle with the hoist.
However, storing it that way for an extended
period could damage the wheel.
To avoid this,

Compact Spare Tire (If Equipped)
Alt.hough the compact spare tire was fully inflated
when your vehicle was new, it can lose air after
a
time. Check the inflation pressure regularly. It should
be
60 psi (420 kPa).
After installing the compact spare on your vehicle,
you should stop as soon as possible and make sure
your spare tire
is correctly inflated. The compact
spare is made to perform well at speeds up to
65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size tire
repaired or replaced where you want. Of course, it’s best
to replace your spare with a full-size tire as soon as you
can. Your spare will last longer and be
in good shape in
case you need it again.

NOTICE:
When the compact spare is installed, don’t take
your vehicle through an automatic
car wash with
guide rails. The compact spare can get caught on
the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t
mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare
tire and its wheel together.
NOTICE:
Tire chains won’t fit your compact spare. Using
them can damage your vehicle and can damage
the chains too. Don’t use tire chains on your
compact spare.
If You’re Stuck: In Sand, Mud,
Ice or Snow
What YOU don’t want to do when your vehicle is stuc
to spin your wheels too fast. The method known
as
:k is
“rocking” can help you get out when you’re stuck, but
you must use caution.
If you let your tires spin at high speed, they can
explode, and
you or others could be injured.
And, the transmission or other parts
of the
vehicle can overheat. That could cause an engine
compartment fire or other damage. When you’re
stuck, spin the wheels as little as possible. Don’t
spin the wheels above
35 mph (55 km/h) as shown
on the speedometer.
