FEATURES OF YOUR HYUNDAI 1- 75
With the "Recirculation" mode selected, and air
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
when turning the ignition to the ON
position if the "AUTO" mode was used
before shutting off the engine.

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.

DRIVING YOUR HYUNDAI 2- 15
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.

3- 4 WHAT TO DO IN AN EMERGENCY
!
!WARNING:While the engine is running, keep hair,
hands and clothing away from moving parts
such as the fan and drive belts to prevent
injury.
D040A02Y-AATSPARE TIRE
The following instructions for the temporary
spare tire should be observed:
1. Check inflation pressure as soon as practi-
cal after installing the spare tire, and adjust
to the specified pressure. The tire pressure
should be periodically checked and main-
tained at the specified pressure while the tire
is stored.
Tire Size
Inflation Pressure
T125/70D15, T125/70R15
60 psi (420 kPa) 5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully remove the radiator cap and
add coolant to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
!
4. As the temporary spare tire is specifically
designed for your car, it should not be used
on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the temporary spare wheel. If
such use is attempted, damage to these
items or other car components may occur.
6. The temporary spare tire pressure should
be checked once a month while the tire is
stored.
Spare Tire Pressure
2. The spare tire should only be used tempo-
rarily and should be returned to the luggage
compartment as soon as the original tire can
be repaired or replaced.
3. Continuous use at speeds of over 50 mph
(80 km/h) is not recommended.
CAUTION:o Do not use snow chains with your tem-
porary spare tire.
o Do not use more than one temporary
spare tire at a time.
