Features of your vehicle
Engine coolant tempera-ture warning light
(if equipped)
This warning light shows the temperature
of the engine coolant when the ignition
switch is ON. The warning light illumi-
nates if the temperature of the engine
coolant is above 248°F (120°C) and the
warning light turns off if the temperature
of the engine coolant is below 239°F
(115°C).
If the warning light illuminates, pull over
and stop as soon as possible and turn off
the engine. Then open the hood and
check the coolant level (If your vehicle
overheats, refer to “If the engine over-
heats” in the Index.) and the water pump
drive belt. If you suspect cooling system
trouble, have your cooling system
checked by a Hyundai dealer as soon as
possible.
✽ ✽ NOTICE
If the engine coolant temperature warn-
ing light illuminates, it indicates over-
heating that may damage the engine.
Low washer fluid level
warning indicator (if equipped)
This warning light indicates the washer
fluid reservoir is near empty. Refill the
washer fluid as soon as possible.
CAUTION
Prolonged driving with the Emission Control SystemMalfunction Indicator Light ( ) illuminated may causedamage to the emission control systems which could effect dri-vability and/or fuel economy.

If the EmissionControl System
Malfunction Indicator Light ( ) illuminates, potential catalyticconverter damage is possible.This could result in loss of enginepower. Have the Engine ControlSystem inspected as soon as pos-sible by an authorized Hyundaidealer.

WARNING
Never remove the radiator cap
when the engine is hot. The engine
coolant is under pressure and
could erupt and cause severe
burns. Wait until the engine is cool
before removing the radiator cap.

What to do in an emergency
5. Start the engine of the vehicle with thebooster battery and let it run at 2,000
rpm, then start the engine of the vehi-
cle with the discharged battery.
If the cause of your battery discharging isnot apparent, you should have your vehi-cle checked by an authorized Hyundaidealer.
Push-starting
Vehicles equipped with automatic
transaxle cannot be push-started.
Follow the directions in this section for
jump-starting. If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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 (automatic transaxle) or neutral (man-
ual 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 con-
ditioning 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 engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized Hyundai dealer for
assistance.
CAUTION
Never tow a vehicle to start itbecause the sudden surge forwardwhen the engine starts could causea collision with the tow vehicle.
CAUTION- Battery cables
Do not connect the jumper cable from the negative terminal of thebooster battery to the negative ter-minal of the discharged battery.This can cause the discharged bat-tery to overheat and crack, releas- ing battery acid.
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.
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 serious burns.

Maintenance
Timing belt
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
Air cleaner filter
A Genuine Hyundai air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
A qualified technician should perform the
operation.
Cooling system
Check the cooling system parts, such as
radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.
Checking the coolant level
WARNING- Removing
radiator cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(Continued)
(Continued)
Turn the engine off and wait untilit cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat- ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
