Features of your vehicle
Malfunction indicator lamp(MIL) (check engine light) (if equipped)
This indicator light is part of the Engine
Control System which monitors various
emission control system components. If
this light illuminates while driving, it indi-
cates that a potential problem has been
detected somewhere in the emissioncontrol system. This light will also illuminate when the
ignition switch is turned to the ON posi-
tion, and will go out in a few seconds
after the engine is started. If it illuminates
while driving, or does not illuminate when
the ignition key is turned to the ON posi-
tion, take your vehicle to your nearest
authorised Hyundai dealer and have the
system checked.
Generally, your vehicle will continue to be
drivable, but have the system checked by
an authorised Hyundai dealer promptly.
Engine coolant tempera-ture warning light
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 120°C (248°F) and the
warning light turns off if the temperature
of the engine coolant is below 115°C(239°F).
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.
CAUTION
Prolonged driving with the
Emission Control SystemMalfunction Indicator Light ( ) illuminated may cause
damage to the emission controlsystems which could effect dri- vability and/or fuel economy.

If the EmissionControl System
Malfunction Indicator Light ( ) illuminates, potential catalytic converter damage is possiblewhich could result in loss of
engine power. Have the EngineControl System inspected as soonas possible by an authorised
Hyundai dealer.
WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant 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 is
not apparent, you should have your vehi-
cle checked by an authorised 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 hand 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 bonnet, stop the engine. Do notopen the bonnet 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 operat-
ing. 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 authorised Hyundai dealer for
assistance.
CAUTION
Never tow a vehicle to start it
because the sudden surge forward when the engine starts could causea collision with the tow vehicle.
CAUTION - Battery cables
Do not connect the jumper cable
from the negative terminal of the booster 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.

Timing belt
Inspect all parts related to the timing belt
for damage and deformation. Replace
any damaged parts immediately.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those intervals
specified in the maintenance schedule.
Make sure that a new vapour hose or fuelfiller 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 movingcomponent 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 isreplaced. 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 part, 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.

Maintenance
Changing the engine oil and filter
Have engine oil and filter changed by an
authorised Hyundai dealer according tothe Maintenance Schedule at the begin-ning of this section.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 thebeginning 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 leadto 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 aresure 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 radiatorcap 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.
WARNING
Used engine oil may cause irrita- tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughlywith soap and warm water as soon
as possible after handling used oil.

Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorised
Hyundai dealer for a cooling systeminspection.
Recommended engine coolant
Use only soft (de-mineralised) water in
the coolant mixture.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.
For mixture percentage, refer to the fol-
lowing table.
Changing the coolant
Have coolant changed by an authorised Hyundai dealer according to theMaintenance Schedule at the beginningof this section.
