COMPACT SPARE TIRE
Although the compact spare 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). The compact spare is made to go up to 3,000
miles (5000 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.
Your anti-lock brake system warning li.ght
may come on when you are
driving
with a compact spare. See “Anti-Lock Brake System Warning
Light” in the Index.

IF YOU’RE STUCK: IN SAND, MUD, ICE OR
SNOW
What you don’t want to do when your vehicle is stuck is to spin your
wheels. The method known
as “rocking” can help you get out when
you’re stuck, but you must use caution.
256

Downloaded from www.Manualslib.com manuals search engine If you let your tires spin at high speed, they can explode and you
or others could be injured. And, the transaxle 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.
-3pannmg your
H ; can destroy parts of your v( cle as well
I as the tires. If you spin the wheels too fast while shifting your
transaxle back and forth, you can destroy your transarj
.
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’
(Reverse) 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 Vehicle” in the Index.

If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative
(-) cable from the battery. This will help keep your battery
from running down.

Contact your dealer to learn how to prepare your vehicle for longer
storage periods.
Battery Power Loss
If you lose battery power or the battery is disconnected, your car’s
computer must be programmed. It takes just over
20 minutes to do it. If
you want to do it yourself, here’s how:
Apply the parking brake.
Make sure the front wheels are straight.
Turn off the Electronic Climate Control.
0 Start the engine in “P” (Park) and let it idle for 15 minutes. Then:
Put your foot on the brake pedal, shift the transaxle to a and let it
idle for
3 minutes or more. Do not accelerate the engine. Then:
0 With the car in a (Drive), turn the Electronic Climate Control to
“Auto” and
let the engine idle for 3 minutes or more.
Turn your engine off.

When It% Time for New Tires
One way to tell when
it’s time for new tires is
to check the treadwear
indicators, which
will
appear when your tires
have only
2/32 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if:
0 You can see the indicators at three places around the tire.
0 You can see cord or fabric showing through the tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep enough to show
0 The tire has a bump, bulge or split.
cord
or fabric.
The tire has a puncture, cut, or other damage that can’t be repaired
well because
of the size or location of the damage.

Downloaded from www.Manualslib.com manuals search engine Buying New Tires
To find out what kind and size of tires you need, look at the Tire-Loading
Information label.
The tires installed on your vehicle when it was new had a Tire
Performance Criteria Specification (TPC Spec) number on each tire’s
sidewall. When you
get new tires, get ones with that same TPC Spec
number. That way, your vehicle will continue to have tires that are
designed to give proper endurance, handling, speed rating, traction, ride
and other things during normal service on your vehicle. If your tires have
an all-season tread design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same size, load range, speed rating and
construction type (bias, bias-belted or radial) as your original tires.
A CAUTION:
Mixing tires could cause you to lose control while driving. If you
mix tires of different sizes or types (radial and bias-belted
tires), the vehicle may not handle properly, and you could have
a
crash. Be sure to use the same size and type tires on all four
wheels.
It’s all right to drive with your compact spare, though. It was
developed
for use on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance. (This applies only
to vehicles sold in the United States.)

Downloaded from www.Manualslib.com manuals search engine Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded
150 would wear one
and a half
(1 1/2) times as well on the government course as a tire graded
100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differences
in road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B, and C. They
represent
the tire’s ability to stop on wet pavement as measured under
controlled conditions
on specified government test surfaces of asphalt
and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking
(straight-ahead) traction tests and does not include cornering \
(turning)
traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions
on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade
C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
Warning: The temperature grade for this tire is established for
a tire that
is properly inflated and not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure.
Those grades are molded
on the sidewalls of passenger car tires.
