all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold.
But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and
do some fairly vigorous exercises
every half hour or
so until help comes.

The CertificatiodTire label in your vehicle will look
similar
to this example. The
Certification/Tire label is found on the rear edge
of
the driver’s door. The label shows the size of your
original tires and the inflation pressures needed to obtain
the gross weight capacity of your vehicle.
This is called the GVWR (Gross Vehicle Weight
Rating). The GVWR includes the weight of the vehicle,
all occupants, fuel, cargo and tongue weight, if pulling
a trailer.
The Certificationnire label also tells you the maximum
weights for the front and rear axles, called the Gross
Axle Weight Rating (GAWR). To find out the actual
loads on your front and rear axles,
you need to go to a
weigh station and weigh your vehicle. Your dealer can
help
you with this. Be sure to spread out your load
equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle, or GAWR
for either the front or rear axle.
And,
if you do have a heavy load, you should spread
it out.

the hole in the rear door frame, above the bumper.
Turn the ratchet toward the right until the tire is
against the underside of the vehicle.
Keep turning the ratchet until you feel at least two
“clicks” when the tire is up all the way. Try to move
the tire with your hands to make sure it is securely
in place.
The compact spare is for temporary use only. Replace
the compact spare tire with a full-size tire as soon as
you can. See “Compact Spare Tire” in the Index. See
the storage instructions label to restore your compact
spare properly.

Downloaded from www.Manualslib.com manuals search engine Compact Spare Tire
Although 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.
I 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.

Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificationire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it
is fastened, can make 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 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. (See
“Changing
a Flat Tire” in the Index.) When
It’s 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
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
0 YOU can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
0 The tire has a bump, bulge or split.
0 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 CertificationRire 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 an
“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.
I A CAUTION:
---
Mixing tires could cause you to lose contrc 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.
Using tires of different sizes may also cause
damage to your vehicle. Be sure to use the same
size and type tires on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for use
on your vehicle.
If you use bias-ply tires on your vehil , the
wheel rim flanges could develop cracks after
many miles of driving.
A tire and/or wheel could
fail suddenly, causing
a crash. Use only radial-ply
tires with the wheels on your vehicle.

Downloaded from www.Manualslib.com manuals search engine Tire Chains
NOTICE:
If your vehicle has P235/65R15 size tires, don’t
use tire chains. They can damage your vehicle
because there’s not enough clearance.
Use another type
of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions.
To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it’s contacting your vehicle, and don’t
spin your wheels.
NOTICE: (Continued) NOTICE: (Continued)
If you do find traction devices that will fit, install
them on the rear tires.
If you have other size tires, use tire chains only
where legal and only when you must. Use only
SAE
Class “S” type chains that are the proper
size for your tires. Install them on the rear axle
tires and tighten them as tightly as possible with
the ends securely fastened, Drive slowly and
follow the chain manufacturer’s instructions,
If
you can hear the chains contacting your vehicle,
stop and retighten them.
If the contact continues,
slow down until it stops. Driving too fast or
spinning the wheels with chains on will damage
your vehicle.
