nor on the instrument panel surface. If there is any leakage from the air freshener onto these areas
(Instrument cluster, instrument panel or air ventilator), it may damage these parts. If the liquid from the air
freshener does leak onto these areas, wash them with water immediately.

B730A01L-AATOperation Tipso To keep dust or unpleasant fumes from
entering the car through the ventilation
system, temporarily set the air intake
control at the position. Be sure to
return the control to the position
when the irritation has passed to keep
fresh air in the vehicle. This will help
keep the driver alert and comfortable.
o Air for the heating/cooling system is
drawn in through the grilles just ahead
of the windshield. Care should be taken
that these are not blocked by leaves,
snow, ice or other obstructions.
o To prevent interior fog on the wind-
shield, set the air intake control to the
fresh air ( ) position and fan speed to
the desired position, turn on the air
conditioning system, and adjust
temperature control to desired tempera-
ture.
AIR CONDITIONING SYSTEMB740A01S-AATAir Conditioning SwitchThe air conditioning is turned on or off by

Air Conditioning Operation
CoolingTo use the air conditioning to cool the
interior:
o Set the air flow control to the face ( )
position.
o Turn on the air conditioning switch by
pushing in on the switch. The air
conditioning indicator light should come
on at the same time.
o Set the air intake control to the fresh air
( ) position.
o Set the temperature control to "Cool".
("Cool" provides maximum cooling. The
temperature may be moderated by
moving the control toward "Warm".)
o Adjust the fan control to the desired
speed. For greater cooling, turn the fan
control to one of the higher speeds or
temporarily select the recirculate ( )
position on the air intake control.

o Set the air flow control to the face ( )
position.
o Turn on the air conditioning switch. The
air conditioning indicator light should
come on at the same time.
o Set the air intake control to the fresh air
( ) position.
o Adjust the fan control to the desired
speed.
o For more rapid action, set the fan at one
of the higher speeds.
o Adjust the temperature control to provide
the desired amount of warmth.
B740D02Y-AATOperation Tipso If the interior of the car is hot when you
first get in, open the windows for a few
minutes to expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to
keep hot air out.
o When moving slowly, as in heavy traffic,
shift to a lower gear. This increases
engine speed, which in turn increases
the speed of the air conditioning
compressor.
o On steep grades, turn the air condition-
ing off to avoid the possibility of the
engine overheating.
o During winter months or in periods when
the air conditioning is not used regularly,
run the air conditioning once every
month for a few minutes. This will help
circulate the lubricants and keep your
system in peak operating condition.

DRIVING YOUR HYUNDAI
16
o Travel lightly. Don't carry unnecessary
weight in your car. Weight reduces fuel
economy.
o Don't let the engine idle longer than
necessary. If you are waiting (and not in
traffic), turn off your engine and restart
only when you're ready to go.
o Remember, your Hyundai does not re-
quire extended warm-up. After the en-
gine has started, allow the engine to run
for 10 to 20 seconds prior to placing the
vehicle in gear. In very cold weather,
however, give your engine a slightly
longer warm-up period.
o Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoided
by shifting at the recommended speeds.
o Use your air conditioning sparingly. The
air conditioning system is operated by
engine power so your fuel economy is
reduced when you use it. o Take care of your tires. Keep them
inflated to the recommended pressure.
Incorrect inflation, either too much or
too little, results in unnecessary tire
wear. Check the tire pressures at least
once a month.
o Be sure that the wheels are aligned
correctly. Improper alignment can result
from hitting curbs or driving too fast over
irregular surfaces. Poor alignment
causes faster tire wear and may also
result in other problems as well as
greater fuel consumption.
o Keep your car in good condition. For
better fuel economy and reduced
maintenance costs, maintain your car
in accordance with the maintenance
schedule in Section 5. If you drive your
car in severe conditions, more frequent
maintenance is required (see Section 5
for details).
o Keep your car clean. For maximum
service, your Hyundai should be kept
clean and free of corrosive materials. It
is especially important that mud, dirt,
ice, etc. not be allowed to accumulate
on the underside of the car. This extra
weight can result in increased fuel
consumption and also contribute to cor-
rosion.
DRIVING FOR ECONOMYC140A02A-AATYou can save fuel and get more miles from
your car if you follow these suggestions:
o Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-rabbit"
starts or full-throttle shifts and maintain
a steady cruising speed. Don't race
between stoplights. Try to adjust your
speed to that of the other traffic so you
don't have to change speeds unneces-
sarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance
from other vehicles so you can avoid
unnecessary braking. This also reduces
brake wear.
o Drive at a moderate speed. The faster
you drive, the more fuel your car uses.
Driving at a moderate speed, especially
on the highway, is one of the most
effective ways to reduce fuel
consumption.
o Don't "ride" the brake or clutch pedal.
This can increase fuel consumption and
also increase wear on these
components. In addition, driving with
your foot resting on the brake pedal may
cause the brakes to overheat, which
reduces their effectiveness and may
lead to more serious consequences.
