BRAKE PAD WEAR WARNING
SOUND
The front disc brake pads have wear indicators
that should make a high-pitched squealing or
scraping noise when new pads are needed. The
sound may come and go or be heard all the time
when the vehicle is moving. It may also be
heard when the brake pedal is pushed down
firmly. Expensive rotor damage will result if the
worn pads are not replaced. See your Hyundai
dealer immediately.
B900A01A-AAT
LIGHTS ON WARNING SOUND
The warning chime sounds when the tail lights
are on and the driver side door is open. This
prevents the battery from discharging by
warning you when the car is left with the tail
lights on. The chime sounds until the tail lights
are turned off.

C160D01A-AATCheck Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge in
your battery can be checked by your Hyundai
dealer or a service station.
C160E01A-AAT
Change to "Winter Weight" Oil if
Necessary
In some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations. If
you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160C01A-AAT
Use High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high quality eth-
ylene glycol coolant in the cooling system. It is
the only type of coolant that should be used
because it helps prevent corrosion in the cooling
system, lubricates the water pump and prevents
freezing. Be sure to replace or replenish your
coolant in accordance with the maintenance
schedule in Section 5. Before winter, have your
coolant tested to assure that its freezing point is
sufficient for the temperatures anticipated dur-
ing the winter.
C160H01A-AAT
Use Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
from freezing, add an approved anti-freeze so-
lution 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.
C160F01A-AAT
Check Spark Plugs and Ignition
System
Inspect your spark plugs as described in Sec-
tion 6 and replace them if necessary. Also
check all ignition wiring and components to be
sure they are not cracked, worn or damaged in
any way.
C160G01A-AAT
To Keep Locks from Freezing
To keep the locks from freezing, squirt an ap-
proved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it
with an approved de-icing fluid to remove the
ice. If the lock is frozen internally, you may be
able to thaw it out by using a heated key. Handle
the heated key with care to avoid injury.

WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!
!WARNING:While the engine is running, keep hands,
long hair and clothing away from moving
parts such as the fan and drive belts to
prevent injury.
D030A02A-AAT
If 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 conditioner is on,
turn it off.
3. If 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 cool-
ant has stopped running or the steaming has
stopped. If there is no visible loss of 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
conditioner had been in use, it is normal for
cold water to be draining from it when you
stop).5. If the water pump drive belt is broken or
coolant is leaking out, stop the engine im-
mediately and call the nearest Hyundai deal-
er for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This may allow coolant to be
blown out of the opening and cause serious
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 water to the reservoir
(Page 6-7) 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 hap-
pens again, call a Hyundai dealer for assis-
tance. Then attach the other end of that cable to a
solid metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2000
rpm.
5. Start the engine in the car with the dis-
charged battery using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2000 rpm for several
minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by
your Hyundai dealer.

THE ENGINE COOLANT
!
G050A01A-AAT G050B01A-AAT
Recommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts. Ad-
ditional corrosion inhibitors or additives should
not be used. The cooling system must be main-
tained with the correct concentration and type of
engine coolant to prevent freezing and corro-
sion.
Never allow the concentration of antifreeze to
exceed the 60% level or go below the 35% level
or damage to the coolant system may result. For
proper concentration when adding or replacing
the coolant, refer to the following table.WARNING:Do not remove the radiator cap when the
engine is hot. When the engine is hot, the
engine coolant is under pressure and may
erupt through the opening if the cap is re-
moved. You could be seriously burned if you
do not observe this precaution. Do not re-
move the radiator cap until the radiator is
cool to the touch.

To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the coolant
should be between the "L" and "F" lines on the
reservoir when the engine is cool. If the level is
below the "L" mark, add engine coolant to bring
it up between "L" and "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and diag-
nosis of the reason.

0.039 ~ 0.043 in.
(1.0 ~ 1.1 mm )
The spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in section 5, or whenever engine per-
formance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, genuine
Hyundai replacement parts are recom-
mended.
G060C01S-GATChanging the Spark Plugs
You will find it easier to change spark plugs if the
engine is cold. Always change one spark plug at
a time. This helps avoid getting the wires mixed
up.
G060C01A-D
1. Remove the center cover on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when
the spark plug is removed.
Recommended Spark Plugs:CHAMPION : RC10YC4
NGK : BKR5ES-11!WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan so that you are not
injured by a rotating fan blade. As the engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each of
its other positions -- "R", "N", "D", "2", "L" -- and
then return to "N" or "P". With the engine still
idling:
1. Open the hood, being careful to keep hands,
hair and clothing clear of any moving parts.
2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.

Checking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
WARNING:The radiator fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan, so that you are not
injured by a rotating fan blade. As the cool-
ant temperature decreases the fan will auto-
matically shut off. This is a normal condition.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should come on
automatically whenever the air conditioner is in
operation.
HLC5006
The power steering fluid level should be checked
regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check to
make certain that the power steering fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir.
NOTE:Grinding noise from the power steering pump
may be heard immediately after the engine is
started in extremely cold conditions (below
-4°F). If the noise stops during warm up,
there is no abnormal function in the system.
It is due to a power steering fluid character-
istic in extremely cold conditions.

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control so-
lenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled by
the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010B01A-AAT
1. CRANKCASE EMISSION CONTROL
SYSTEM
The positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies filtered fresh air to
the crankcase through the air intake hose. In-
side the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.
H010A01A-AAT
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
H010D01A-AAT3. EXHAUST EMISSION
CONTROL SYSTEM
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010C01S-AAT
2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the atmo-
sphere.)
