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.

Driving your vehicle
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high quality
ethylene 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, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in Section 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in Section
7. The level of charge in your battery can
be checked by an authorized Hyundai
dealer or a service station.
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 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized Hyundai dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as described in
Section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
To keep locks from freezing
To keep the locks from freezing, squirt an
approved 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.
Use approved window washer
anti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorized Hyundai
dealer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.

Driving your vehicle

Driving on grades
Reduce speed and shift to a lower gear
before you start down a long or steep
downgrade. If you don’t shift down, you
might have to use your brakes so much
that they would get hot and no longer
operate efficiently.
On a long uphill grade, shift down and
reduce your speed to around 20 mph (30
km/h) to reduce the possibility of engine
and transaxle overheating.
If your trailer weighs more than the max-
imum trailer weight without trailer brakes
and you have an automatic transaxle,
you should drive in D (Drive) when tow-
ing a trailer.
Operating your vehicle in D (Drive) when
towing a trailer will minimize heat build up
and extend the life of your transaxle.
Parking on hills
Generally, if you have a trailer attached to
your vehicle, you should not park your
vehicle on a hill. People can be seriously
or fatally injured, and both your vehicle
and the trailer can be damaged if unex-
pectedly roll down hill.
However, if you ever have to park your
trailer on a hill, here's how to do it:
1. Pull the vehicle into the parking space.
Turn the steering wheel in the direction
of the curb (right if headed down hill,
left if headed up hill).
2. If the vehicle has a manual transaxle, place the car in neutral. If the vehicle
has an automatic transaxle, place the
car in P (Park).
3. Set the parking brake and shut off the vehicle.
4. Place chocks under the trailer wheels on the down hill side of the wheels.CAUTION
When towing a trailer on steep grades (in excess of 6%) payclose attention to the enginecoolant temperature gauge toensure the engine does not over- heat. If the needle of the coolanttemperature gauge moves acrossthe dial towards “H” (HOT), pullover and stop as soon as it is safeto do so, and allow the engine toidle until it cools down. You mayproceed once the engine hascooled sufficiently.
You must decide driving speed depending on trailer weight anduphill grade to reduce the possi-bility of engine and transaxleoverheating.
WARNING- Parking on a hill
Parking your vehicle on a hill with a
trailer attached could cause seri-
ous injury or death, should the trail-
er break lose.

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
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 is
cool.
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 authorized
Hyundai dealer for a cooling system
inspection.
Recommended engine coolant
Use only soft (de-mineralized) water inthe 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 specified
coolant.
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.
