Use high quality ethylene gly-
col 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 cool-
ing system, lubricates 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 battery 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 igni-
tion system
Inspect your spark plugs as
described in section 7 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.
WARNING- Tire chains
The use of chains may adversely affect vehicle han-
dling.
Do not exceed 20 mph (30 km/h) or the chain manufac-
turer’s recommended speed
limit, whichever is lower.
Drive carefully and avoid bumps, holes, sharp turns,
and other road hazards, which
may cause the vehicle to
bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

What to do in an emergency
66
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, 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 soonas it is safe to do so.
2. Place the shift lever in P (automat- ic transmission) or neutral (manual
transmission) 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 underneath the hood,
stop the engine. Do not open the
hood until the coolant has flow
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing 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 condition-
ing 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 bro-
ken or engine coolant is leaking
out, stop the engine immediately
and call the nearest authorized
HYUNDAI dealer for assistance.
6.If you cannot find the cause of the overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark. 7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in coolant to be
blown out of the opening and
cause serious burns.
CAUTION
Serious loss of coolant indicatesthere is a leak in the cooling sys-tem and this should be checkedas soon as possible by anauthorized HYUNDAI dealer.

are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
WARNING- Maintenance work
Performing maintenance work on a vehicle can be danger-
ous. You can be seriously
injured while performing some
maintenance procedures. If
you lack sufficient knowledge
and experience or the proper
tools and equipment to do the
work, have it done by an
authorized HYUNDAI dealer.
Working under the hood with the engine running is danger-
ous. It becomes even more
dangerous when you wear
jewelry or loose clothing.
These can become entangled
in moving parts and result in
injury. Therefore, if you must
run the engine while working
under the hood, make certain
that you remove all jewelry
(especially rings, bracelets,
watches, and necklaces) and
all neckties, scarves, and sim-
ilar loose clothing before get-
ting near the engine or cool-
ing fans.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
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 cli-
mate.Checking the coolant level
ENGINE COOLANT
(Continued)
Even if the engine is not oper-ating, do not remove the radi-
ator 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.
WARNING
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
Turn the engine off and wait until it 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 counterclock-
wise to remove it.
