from within the passenger compartment will be
drawn through the heating system and heated
or cooled according to the function selected.
NOTE:o It should be noted that prolonged opera-
tion of the heating system in "recircula-
tion" mode will give rise to fogging of the
windshield and side windows and the air
within the passenger compartment will
become stale. In addition, prolonged
use of the air conditioning with the "Re-
circulation" mode selected may result in
the air within the passenger compart-
ment becoming excessively dry.
o When the ignition switch is turned "ON"
the air intake control will change to " "
mode (regardless of the switch posi-
tion). This is normal operation. The air
intake control operates in "AUTO" mode

B760A06Y-AATAIR CONDITIONER FILTER (FOR
EVAPORATOR AND BLOWER UNIT)
(If installed)
The air conditioner filter is located in the evapo-
rator behind the glove box.
It operates to decrease pollutants the amount of
entering the car.
CAUTION:o Replace the filter every 12,000 miles
(20,000 km) or once a year.
If the car is being driven in severe condi-
tions such as dusty, rough roads, more
frequent air conditioner filter inspec-
tions and changes are required.
o When the air flow rate is suddenly de-
creased, it must be checked at an autho-
rized dealer.
o If your vehicle is not equipped with this
filter, it can be installed by your dealers.
Check with your dealer for details.
!
B740D01Y-AATOperation Tips
o 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 conditioning off
to avoid the possibility of the engine over-
heating.
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 lubri-
cants and keep your system in peak oper-
ating condition.

!WARNING: ENGINE EXHAUST CAN BE DANGEROUS!
C010A03A-AATEngine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the windows immediately.
o Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation.
o Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear a change
in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the exhaust system checked
as soon as possible by your Hyundai dealer.
o Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your garage any
longer than it takes to start the engine and back the car out.
o Avoid idling the engine for prolonged periods with people inside the car.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area with the air intake
set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid/ tail gate open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are kept clear
of snow, ice, leaves or other obstructions.
!PROPOSITION 65 WARNING:Engine exhaust and a wide variety of automobile components and parts, including components found in the interior furnishings
in a vehicle, contain or emit chemicals known to the State of California to cause cancer and birth defects and reproductive harm.
In addition, certain fluids contained in vehicles and certain products of component wear contain or emit chemicals known to
the State of California to cause cancer and birth defects or other reproductive harm.

C160J01A-AATDon't Let Ice and Snow Accumulate
Underneath
Under some conditions, snow and ice can build
up under the fenders and interfere with the
steering. When driving in severe winter condi-
tions where this may happen, you should peri-
odically check underneath the car to be sure the
movement of the front wheels and the steering
components is not obstructed.
C160I01A-AAT
Don't Let Your Parking Brake Freeze
Under some conditions your parking brake can
freeze in the engaged position. This is most
likely to happen when there is an accumulation
of snow or ice around or near the rear brakes
or if the brakes are wet. If there is a risk the
parking brake may freeze, apply it only tempo-
rarily while you put the gear selector lever in "P"
(automatic) or in first or reverse gear (manual
transaxle) and block the rear wheels so the car
cannot roll. Then release the parking brake.
C160H01A-AATUse Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
from freezing, add an approved anti-freeze
solution in accordance with instructions on the
container. Window washer anti-freeze is avail-
able from Hyundai dealers and most auto parts
outlets. Do not use engine coolant or other types
of anti-freeze as these may damage the finish.
C160K01A-AAT
Carry Emergency Equipment
Depending on the severity of the weather where
you drive your car, you should carry appropri-
ate emergency equipment. Some of the items
you may want to carry include tire chains, tow
straps or chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a window scraper,
gloves, ground cloth, coveralls, a blanket, etc.
C170A01A-AATHIGHER SPEED MOTORING
Pre-Trip Inspections
1. Tires:
Adjust the tire inflation pressures to specifica-
tion. Low tire inflation pressures will result in
overheating and possible failure of the tires.
Avoid using worn or damaged tires which may
result in reduced traction or tire failure.
NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.
2. Fuel, engine coolant and engine oil:
High speed travel consumes 1.5 times more
fuel than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result in
overheating of the engine.

CORROSION PREVENTION AND APPEARANCE CARE 4- 5
Take a piece of cheese cloth and using any mild
soap and lukewarm water, work up a good
lather. Thoroughly wash the leather. Wipe clean
with a slightly damp cloth and dry with soft cloth.
Do this as often as the leather becomes
soiled.
During tanning operations, sufficient oils are
incorporated through processing that none need
be applied during the life of the leather. Oil
applied to the finished surface will in no way help
the leather and may do more harm than good.
Varnishes and furniture polishes should never
be used under any conditions.E040D01A-AATCleaning the Seat Belts
To clean the seat belts, use a cloth or sponge
with mild soap or detergent and warm water. Do
not use strong detergents, dye, bleach or abra-
sive materials on the seat belts as this may
weaken the fabric.
While cleaning the belts, inspect them for ex-
cessive wear, cuts, fraying or other signs of
damage and replace them if necessary.
E040C01A-AATCleaning the Carpets
Use a foam-type carpet cleaner. Cleaners of
this type are available in aerosol cans in liquid
form or powder. Read the instructions and
follow them exactly. Using a vacuum cleaner
with the appropriate attachment, remove as
much dirt from the carpets as possible. Apply
the foam following the manufacturer's direc-
tions, then rub in overlapping circles. Do not add
water. These cleaners work best when the
carpet is kept as dry as possible.
E050A01A-AATAny Questions?
If you have any questions about the care of your
car, consult your Hyundai dealer.
E040E01A-AATCleaning the Windows
You may use any household window cleaner on
the windows. However, when cleaning the in-
side of the rear window be careful not to damage
the rear window defroster wiring.
