B290A03A-AATENGINE COOLANT TEMPERATURE
GAUGE
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 adding coolant to the
reservoir.The normal range is approximately in the
middle between "H" and "C". If it moves
across the dial to "H" (HOT), pull over and
stop as soon as possible and turn off the
engine. Then open the hood and, after the
engine has cooled, check the coolant level
(See "If the engine overheats" on the page
3-4.) 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.

SMOOTH CORNERINGC150A01A-AATAvoid braking or gear changing in corners,
especially when roads are wet. Ideally,
corners should always be taken under
gentle acceleration. If you follow these
suggestions, tire wear will be held to a
minimum.
C160A01A-AATThe more severe weather conditions of
winter result in greater wear and other
problems. To minimize the problems of
winter driving, you should follow these
suggestions:C160B01A-AATSnowy or Icy ConditionsTo drive your vehicle in deep snow, it may
be necessary to use snow tires or to install
tire chains on your tires. If snow tires are
needed, it is necessary to select tires
equivalent in size and type of the original
equipment tires. Failure to do so may
adversely affect the safety and handling of
your car. Furthermore, speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially very
hazardous practices.
During deceleration, use engine braking to
the fullest extent. Sudden brake applications
on snowy or icy roads may cause skids to
occur. You need to keep sufficient distance
between the vehicle in operation in front
and your vehicle. Also, apply the brake
gently. It should be noted that installing tire
chains on the tire will provide a greater
driving force, but will not prevent side skids.NOTE:Tire chains are not legal in all states.
Check state laws before fitting tire
chains.WINTER DRIVING
C160D01A-AATCheck Battery and CablesWinter 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.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai 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, 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 during the winter.

C160J01A-AATDon't Let Ice and Snow Accumulate
UnderneathUnder some conditions, snow and ice can
build up under the fenders and interfere
with the steering. When driving in severe
winter conditions where this may happen,
you should periodically check underneath
the car to be sure the movement of the front
wheels and the steering components is
not obstructed.C160I01A-AATDon't Let Your Parking Brake FreezeUnder some conditions your parking brake
can freeze in the engaged position. This
is most likely to happen when there is an
accumulation of snow or ice around or
near the rear brakes or if the brakes are
wet. If there is a risk the parking brake may
freeze, apply it only temporarily while you
put the gear selector lever in "P" (automatic)
or in first or reverse gear (manual transaxle)
and block the rear wheels so the car cannot
roll. Then release the parking brake.
C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from Hyundai dealers and most
auto parts outlets. Do not use engine coolant
or other types of anti-freeze as these may
damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo 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.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in
Section 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.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn 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.

C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather
where you drive your car, you should carry
appropriate emergency equipment. Some
of the items you may want to carry include
tire chains, tow straps or chains, flashlight,
emergency flares, sand, a shovel, jumper
cables, a window scraper, gloves, ground
cloth, coveralls, a blanket, etc.
HIGHER SPEED MOTORINGC170A02A-AATPre-Trip Inspections1. Tires:
Adjust the tire inflation pressures to speci-
fication. Low tire inflation pressures will
result in overheating and possible failure
of the tires.
Avoid using worn or damaged tires which
may result in reduced traction or tire failure.NOTE:Never exceed the maximum tire inflation
pressure shown on the tires.2. Fuel, engine coolant and engine oil:
High speed travel consumes more fuel
than urban motoring. Do not forget to check
both engine coolant and engine oil.
3. Drive belt:
A loose or damaged drive belt may result
in overheating of the engine.
WARNING:
o Underinflated or overinflated tires
can cause poor handling, loss of
vehicle control, and sudden tire failure
leading to accidents, injuries, and
even death. Always check tires are
properly inflated before driving. Refer
to pages 2-23 and 8-3 for proper tire
pressures and further information.
o Driving on tires with no or insufficient
tread is dangerous. Worn-out tires
can result in loss of vehicle control,
collisions, injury, and even death.
Worn-out tires should be replaced as
soon as possible and should never be
used for driving. Always check tire
tread before driving your car. Refer
to 8-10 for further information and
tread limits.

C190D01S-AATSafety ChainsShould the hitch connection between your
car and the trailer or vehicle you are towing
fail, the trailer or vehicle could wander
dangerously across other lanes of traffic
and ultimately leave the roadway. To
eliminate this potentially dangerous
situation, safety chains, attached between
your car and the trailer or towed vehicle,
are required in most states.
CAUTION:
o Never connect a trailer brake system
directly to the vehicle brake system.
o When towing a trailer on steep grades
(in excess of 6%) pay close attention
to the engine coolant temperature
gauge to ensure the engine does not
overheat. If the needle of the coolant
temperature gauge moves across the
dial towards "H" (HOT), pull over and
stop as soon as it is safe to do so, and
allow the engine to idle until it cools
down. You may proceed once the
engine has cooled sufficiently.

Gross Axle WeightGross Vehicle
Weight2. The total gross vehicle weight with
trailer must not exceed the Gross
Vehicle Weight Rating (GVWR) shown
on the vehicle identification plate (see
page 8-2). The total gross vehicle
weight is the combined weight of the
vehicle, driver, all passengers and
their luggage, cargo, hitch, trailer
tongue load and other optional
equipment.

Tongue Load Total Trailer Weight
o Keep the tongue load 10% of the total
trailer load.
o
Tongue load
o Tongue loads can be increased or de-
creased by re-distributing the load in
the trailer.
This can be verified by checking the
total weight of the loaded trailer and
then checking the load on the tongue.

x 100 = 10% (MAX)
Total trailer weight
NOTE:1. Never load the trailer with more weight
in the back than in the front. About
60% of the trailer load should be in the
front half on the trailer and the
remaining 40% in the rear.

34WHAT TO DO IN AN EMERGENCY
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.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the
engine immediately and call the nearest
Hyundai dealer for assistance.
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 se-
rious 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 coolant to the reservoir (page 6-9)
to bring the fluid level in the reservoir up
to the halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If
overheating happens again, call a
Hyundai dealer for assistance.
CAUTION:
Serious loss of coolant indicates there is
a leak in the cooling system and this
should be checked as soon as possible
by a Hyundai dealer.
D030A02A-AATIf 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 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"
(automatic) or neutral (manual
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 conditioning had been
in use, it is normal for cold water to be
draining from it when you stop).

VEHICLE MAINTENANCE REQUIREMENTS2
F010C01A-AATSpecified Scheduled ProceduresThese are the procedures such as
inspections, adjustments and
replacements that are listed in the
maintenance charts starting on page 5-4.
These procedures must be performed at
the intervals shown in the maintenance
schedule to assure that your warranty
remains in effect. Although it is strongly
recommended that they be performed by
the trained technicians at your Hyundai
dealer, these procedures may be per-
formed at any qualified service facility.
It is suggested that genuine Hyundai
service parts be used for any required
repairs or replacements. Other parts of
equivalent quality such as engine oil,
engine coolant, manual or auto transaxle
oil, brake fluid and so on which are not
supplied by Hyundai Motor Company or its
distributor may be used without affecting
your warranty coverage but you should
always be sure these are equivalent to the
quality of the original Hyundai parts. Your
Owner's Handbook provides further
information about your warranty coverage.
F010A01A-AATService RequirementsTo ensure that you receive the greatest
number of miles of satisfying operation
from your Hyundai, certain maintenance
procedures must be performed. Although
careful design and engineering have
reduced these to a minimum, those that
are required are of the utmost importance.
It is your responsibility to have these main-
tenance procedures performed to comply
with the terms of the warranties covering
your new Hyundai. The Owner's Handbook
supplied with your new vehicle provides
further information about these warranties.
F010B01A-AATMaintenance RequirementsThe maintenance required for your
Hyundai can be divided into three main
areas:
o Specified scheduled procedures
o General checks
o Do-it-yourself maintenance
