B760A01NF-AATAIR CONDITIONER FILTER (FOR
EVAPORATOR AND BLOWER UNIT)
(If Installed)
The air conditioner filter is located in the right
side of the instrument panel.
It operates to decrease the amount of pollutants
entering the car.
To replace the air conditioner filter, refer to page

CAUTION:
o Replace the filter every 10,000 miles
(15,000 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.

B980F01NF-AATDefrost SwitchWhen the "Defrost" button is pressed, the " "
mode will be automatically selected and the air
will be discharged through the windshield de-
froster nozzle, side defroster nozzle and side
ventilator. To assist in defrosting, the air condi-
tioning will operate if ambient temperature is
higher than 34.7°F(1.5°C) and automatically
turns off if the ambient temperature drops below
33.08°F(0.6°C).

DRIVING YOUR HYUNDAI
16
o Remember, your Hyundai does not require
extended warm-up. As soon as the engine
is running smoothly, you can drive away. In
very cold weather, however, give your en-
gine 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 result-
ing 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.
SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally, corners
should always be taken under gentle accelera-
tion. If you follow these suggestions, tire wear
will be held to a minimum.
C160A01A-AATThe more severe weather conditions of winter
result in greater wear and other problems. To
minimize the problems of winter driving, you
should follow these suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type of the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.WINTER DRIVING

34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
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.
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 add coolant to the reservoir
(page 6-9) 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.
D030A02A-AATIf your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soon as it is safe
to do so.
2. Place the gear selector lever in "P" (auto-
matic) or neutral (manual transaxle) and set
the parking brake. If the air conditioning is on,
turn it off.
3. If engine coolant is running out under the car
or steam is coming out from the hood, stop
the engine. Do not open the hood until the
coolant has stopped running or the steaming
has stopped. If there is no visible loss of
engine coolant and no steam, leave the
engine running and check to be sure the
engine cooling fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that
it is tight. If the drive belt seems to be
satisfactory, check for coolant leaking from
the radiator, hoses or under the car. (If the
air conditioning had been in use, it is normal
for cold water to be draining from it when you
stop).

G140C01A-AATLubricationTo lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.
!
G120E02A-AATAdding Brake Fluid
WARNING:Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.
AIR CONDITIONING CARE!
G140A01A-AATKeeping the Condenser CleanThe air conditioning condenser (and engine
radiator) should be checked periodically for
accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.G140B01A-AATChecking the Air Conditioning Opera-
tion1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:
Running the air conditioning system for
extended periods of time with a low refrig-
erant level may damage the compressor.
