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 ser-
vice station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high qual-
ity 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 sched-
ule in Section 5. Before winter, have your
coolant tested to assure that its freezing
point is sufficient for the temperatures an-
ticipated during the winter.
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 ad-
versely affect the safety and handling of
your car. Furthermore, speeding, rapid
acceleration, sudden brake applications,
and sharp turns are potentially very haz-
ardous practices.
During deceleration, use engine braking
to the fullest extent. Sudden brake applica-
tions 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 install-
ing 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.
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 compo-
nents 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.

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 near-
est 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 over-
heating, wait until the engine tempera-
ture has returned to normal. Then, if
coolant has been lost, carefully add
coolant to the reservoir (page 6-7) 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 over-
heating 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.
D030A01TG-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" and
set the parking brake. If the air condi-
tioning 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 un-
der the car. (If the air conditioning had
been in use, it is normal for cold water
to be draining from it when you stop).

CHECKING THE ENGINE OILG030B01O-AATRecommended OilThe engine oil quality should meet the
following classification.
API SJ, SL or ABOVE,
ILSAC GF-3 or ABOVE
G030B01JM-U G030A01A-AAT
Engine oil is essential to the performance
and service of the engine. It is suggested
that you check the oil level at least once a
week in normal use and more often if you
are on a trip or driving in severe conditions.
MAINTENANCE PRECAU-
TIONS
!
G020D01TG-GATImproper or incomplete service may result
in problems. This section gives instruc-
tions only for the maintenance items that
are easy to perform.
Several procedures should be done by an
authorized Hyundai dealer.NOTE:Improper owner maintenance during the
warranty period may affect warranty
coverage.
WARNING:
o Performing maintenance work on a
vehicle can be dangerous. You can be
seriously injured while performing
some maintenance procedures. If you
lack sufficient knowledge and experi-
ence or the proper tools and equip-
ment to do the work, have it done by an
authorized Hyundai dealer.
o Working under the hood with the en-
gine running is dangerous. 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 similar
loose clothing before getting near the
engine or cooling fans.

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant
in a 50/50 mix with water. The engine
coolant should be compatible with alumi-
num engine parts. Additional corrosion
inhibitors or additives should not be used.
The cooling system must be maintained
with the correct concentration and type of
engine coolant to prevent freezing and
corrosion. Never allow the concentration
of antifreeze to exceed the 60% level or go
below the 35% level, or damage to the
cooling system may result. For proper con-
centration when adding or replacing the
engine coolant, refer to the following table.

G050C01TG-GATTo Check the Coolant LevelThe coolant level can be seen on the side
of the plastic coolant reservoir. The level of
the coolant should be between the "L" and
"F" lines on the reservoir when the engine
is warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
it up to "F". If the level is low, inspect for
coolant leaks and recheck the fluid level
frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01TG
!
CAUTION:
o Engine coolant can damage the finish
of your car. If you spill engine coolant
on the car, wash it off thoroughly with
clean water.
o The engine in your vehicle has alumi-
num engine parts and must be pro-
tected by an ethylene-glycol base
coolant to prevent corrosion and freez-
ing.
Do not use hard water. Hard water can
cause engine damage from corro-
sion, overheating or freezing.
WARNING:
The cooling fan is controlled by engine
coolant temperature and may some-
times operate even when the engine is
not running. Use extreme caution when
working near the blades of the coolant
fan so that you are not injured by a
rotating fan blade. As the engine coolant
temperature decreases, the fan will au-
tomatically shut off. This is a normal
condition.

2. Pull the glove box cylinder to unlock the
glove box retainer.
HTG2167 G140C01A-AAT
LubricationTo lubricate the compressor and the seals
in the system, the air conditioning should
be run for at least 10 minutes each week.
This is particularly important during cool
weather when the air conditioning system
is not otherwise in use.
AIR CONDITIONING CARE
!
G140A01A-AATKeeping the Condenser CleanThe air conditioning condenser (and en-
gine radiator) should be checked periodi-
cally for accumulation of dirt, dead insects,
leaves, etc. These can interfere with maxi-
mum cooling efficiency. When removing
such accumulations, brush or hose them
away carefully to avoid bending the cool-
ing fans.G140B01A-AATChecking the Air Conditioning Op-
eration1. Start the engine and let it run at a fast idle
for several minutes with the air condi-
tioning set at the maximum cold setting.
2. If the air coming out of the in-dash vents
is not cold, have the air conditioning
system inspected by your Hyundai
dealer.
CAUTION:
Running the air conditioning system for
extended periods of time with a low re-
frigerant level may damage the com-
pressor.

CAUTION:
An open fuse indicates that there is a
problem in the electrical circuit. If you
replace a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a
Hyundai dealer for diagnosis and repair.
Never replace a fuse with anything ex-
cept a fuse with the same or a lower
amperage rating. A higher capacity fuse
could cause damage and create a fire
hazard.NOTE:See page 6-33 for the fuse panel descrip-
tions.
G200C01CM-GATPower ConnectorNOTE:
o If the power connector is pulled up
from the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,

automatically if the engine coolant tem-
perature is high or whenever the air con-
ditioning is in operation.
G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power
steering hose connections for fluid leak-
age at those intervals specified in the ve-
hicle maintenance schedule in Section 5.
The power steering hoses should be re-
placed if there is severe surface cracking,
pulling, scuffing or worn spots. Deteriora-
tion of the hose could cause premature
failure.NOTE:Grinding noise from the power steering
pump may be heard immediately after
the engine is started in extremely cold
conditions (below - 4°F). If the noise stops
during warm up, there is no abnormal
function in the system. It is due to a
power steering fluid characteristic in
extremely cold conditions.
Recommended FluidUse PSF-4 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.
