Fuel Economy
The condition of your car and yourdriving habits are the two most
important things that affect the fuel
mileage you get.
Vehicle Condition Always maintain your car according to the maintenance schedule. This
will keep it in top operating condition.
An important part of that mainte- nance is the Owner MaintenanceChecks (see page 199). For
example, an underinflated tire
causes more "rolling resistance,"
which uses fuel. It also wears out
faster, so check the tire pressure at least monthly.
In winter, the build-up of snow on
your car's underside adds weight and rolling resistance. Frequent cleaning
helps your fuel mileage and reduces
the chance of corrosion. Driving Habits
You can improve fuel economy by driving moderately. Rapid acceler-
ation, abrupt cornering, and hard
braking use more fuel.
Always drive in the highest gear that allows the engine to run and acceler-
ate smoothly.
Depending on traffic conditions, try
to maintain a constant speed. Every
time you slow down and speed up,
your car uses extra fuel. Use the cruise control, when appropriate, to
increase fuel economy. A cold engine uses more fuel than a
warm engine. It is not necessary to
"warm-up" a cold engine by letting it
idle for a long time. You can drive away in about a minute, no matter
how cold it is outside. The engine
will warm up faster, and you get
better fuel economy. To cut down on
the number of "cold starts," try to combine several short trips into one.
The air conditioning puts an extra load on the engine which makes it
use more fuel. Turn off the A/C tocut down on air conditioning use.Use the flow-through ventilation
when the outside air temperature is moderate.
Before Driving

Driving in Bad Weather
Visibility — Being able to seeclearly in all directions and being
visible to other drivers are important in all weather conditions. This is
more difficult in bad weather. To be
seen more clearly during daylight
hours, turn on your headlights.
Inspect your windshield wipers and
washers frequently. Keep the wind- shield washer reservoir full of theproper fluid. Have the windshield
wiper blades replaced if they start to streak the windshield or leave parts
unwiped. Use the defroster and air
conditioning to keep the windows
from fogging up on the inside (see pages 112 and 118). Traction — Check your tires
frequently for wear and properpressure. Both are important in
preventing "hydroplaning" (loss of
traction on a wet surface). In the
winter, mount snow tires on all four
wheels for the best handling.
Watch road conditions carefully, they can change from moment tomoment. Wet leaves can be as slip-
pery as ice. "Clear" roads can have
patches of ice. Driving conditions
can be very hazardous when theoutside temperature is near freezing.
The road surface can become covered with areas of water puddlesmixed with areas of ice, so your
traction can change without warning.
Be careful when downshifting. If
traction is low, you can lock up the
drive wheels for a moment and cause
a skid. Be very cautious when passing, or
being passed by other vehicles. The spray from large vehicles reduces
your visibility, and the wind buffeting can cause you to lose control.

1. Turn the ignition ON (II). Turnthe heater temperature controldial to maximum heat (climate
control to 90°F/32°C). Turn off
the ignition. Open the hood. Make sure the engine and radiator are
cool to the touch.
2. Remove the radiator cap.

5. When the coolant stops draining, tighten the drain plug at the
bottom of the radiator.

If Your Engine Overheats
The pointer of your car's tempera-ture gauge should stay in the mid-range under most conditions. It may
go higher if you are driving up a long steep hill on a very hot day. If it
climbs to the red mark, you should
determine the reason.
Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your car can overheat for severalreasons, such as lack of coolant or amechanical problem. The only
indication may be the temperature
gauge climbing to or above the red mark. Or you may see steam orspray coming from under the car or
engine cover. In either case, you should take immediate action.
Steam and spray from an
overheated engine can
seriously scald you.Do not open the hood if steam
is coming out. 1. Safely pull to the side of the road.
Put the transmission in Neutral or
Park and set the parking brake.
Turn off the climate control and all other accessories. Turn on the
hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to overloading(climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid- point then continue driving.

NOTICE

If Your Engine Overheats
4. If the temperature gauge stays atthe red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the
hood.
6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 277).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page
151). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have toadd coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator.
Removing the radiator cap
while the engine is hot can
cause the coolant to spray out,
seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.
9. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the
pressure releases, push down on
the cap and turn it until it comes off. 10. Start the engine and set the
temperature control dial to
maximum (climate control to
FULL AUTO at 90°F/32°C). Add
coolant to the radiator up to the
base of the filler neck. If you do not have the proper coolant
mixture available, you can add
plain water. Remember to have
the cooling system drained and refilled with the proper mixture assoon as you can.
11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goes
back to the red mark, the engine
needs repair. (See Emergency
Towing on page 277

.)
12. If the temperature stays normal, check the coolant level in theradiator reserve tank. If it has
gone down, add coolant to the
MAX mark. Put the cap back on
tightly.

DOT Tire Quality Grading (U.S. Cars)
The tires on your car meet all U.S.Federal Safety Requirements. All
tires are also graded for treadwear,
traction, and temperature perform-ance according to Department of
Transportation (DOT) standards.
The following explains these gradings.
Uniform Tire Quality Grading Quality grades can be found where
applicable on the tire sidewall
between the tread shoulder and the maximum section width. For
example:
Treadwear 200
Traction AA
Temperature A Treadwear
The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlledconditions on a specified government
test course. For example, a tire
graded 150 would wear one and one
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 condi-
tions 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
The traction grades, from highest to
lowest, are AA, A, B, and C. Those
grades represent the tire's ability tostop 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 onstraight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
