Low Coolant Warning Light
LOW COOLANT
If this light comes on, your
system is low on coolant
and the engine may
overheat. See “Engine
Coolant”
in the Index and
have your vehicle serviced
as soon as you can.
The light will come on briefly when your ignition is
turned
on to show you that it is working properly.
Low Tire Light (If Equipped)
LOW
TIRE
The tire pressure monitor
system can alert you to
a
large change in the pressure
in one tire. After the system has “learned”
tire pressures with
properly inflated tires, the
LOW TIRE light will come
on if the pressure in one tire becomes
12 psi (83 kPa)
lower than the other three tires. The tire pressure
monitor system won’t alert you if the pressure in more
than one tire
is low, if the system is not yet calibrated, or
if the vehicle is moving faster than
70 mph (1 10 kdh).
When the
LOW TIRE light comes on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If a Tire Goes Flat” in the Index.)
Also check the tire pressure in all four tires as soon
as
you can. See “Inflation - Tire Pressure” in the Index.
The light will stay on until you turn off the ignition or
reset the system. See “Tire Pressure Monitor System” in
the Index.
The
LOW TIRE light also comes on briefly when you
turn the ignition key to RUN. If the light doesn’t come
on then, have it fixed
so it will be there to tell you if the
pressure in a tire is low or high.

Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later
on
with your headlamps. Let the heater run for a while.
Then,
shut the engine off and close the window almost
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.
Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly calry. The Tire-Loading Information label
is inside the trunk lid. The label tells you the proper size,
speed rating and recommended inflation pressures for
the tires
on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight you can carry. This
weight is called the vehicle capacity weight and includes
the weight of all occupants, cargo and all
nonfactory-installed options.

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 remhrly. It should be
60 psi (420 Wa).
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 kmk) 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. You must calibrate
the tire pressure monitor system after installing or
removing the compact spare. See “Tire Pressure
Monitor”
in the Index. The system may not work
correctly when the compact spare
is installed on the
vehicle. 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.

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the
inside
of the trunk lid, shows the correct inflation
pressures for your tires when they’re cold. “Cold”
means your vehicle has been sitting for at least three
hours or driven no more than
1 mile (1.6 km).
NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is
all right. It’s not. If your tires
don’t have enough air (underinflation), you can
get the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy.
NOTICE: (Continued) NOTICE:
(Continued)
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazards.
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire. It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve
stems. They help prevent leaks by keeping out
dirt
and moisture.

Tire Pressure Monitor System (If Equipped)
The tire pressure monitor system can alert you to a large
change in the pressure
of one tire. The system “learns”
the pressure at each tire throughout the operating speed
range of your vehicle. The system normally takes
between
45 and 90 minutes of driving to learn the tire
pressures. This time may be longer depending on your
individual driving habits. Learning need not be
accumulated during
a single trip. Once learned, the
system will remember the tire pressures until the system
is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in
one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire pressure monitor system
won’t alert you if the pressure
in more than one tire is
low, if the system is not properly calibrated, or if the
vehicle
is moving faster than 70 mph (1 10 kdh).
The tire pressure monitor system detects differences
in tire rotation speeds that are caused by changes
in
tire pressure. The system can alert you about a low
tire
-- but it doesn’t replace normal tire maintenance.
See “Tires” in the Index. When the LOW
TIRE light comes
on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If
a Tire Goes Flat” in the Index.)
Also check
the tire pressure in all four tires as soon as
you can. See “Inflation
- Tire Pressure” in the Index.
The light will come on and stay on
until you turn off the
ignition or press the
RESET button.
Don’t reset the tire pressure monitor system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the tire
pressure monitor system will not work properly and may
not alert you when
a tire is low.
Any time
you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor system.
You’ll also need to reset the system whenever you buy
new tires and whenever the vehicle’s battery has been
disconnected.
To reset (calibrate) the system,
turn the ignition switch
to
RUN. Then press and hold the RESET button for
about five seconds.

When rotating your tires, always use the correct
rotation pattern shown here.
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 Tire-Loading
Information 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
11 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.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
