Don’t Let Ice and Snow Accumulate
Underneath
Under some conditions, snow and ice can build
up under the fenders and interfere with the
steering. When driving in severe winter condi-
tions where this may happen, you should peri-
odically check underneath the car to be sure
the movement of the front wheels and the
steering components is not obstructed. transaxle) and block the rear wheels so the car
cannot roll. Then release the parking brake.
C160D01F-AATCheck Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6 (See page 6-16). The
level of charge in your battery can be checked
by your Hyundai dealer or a service station.
C160E01A-AATChange to "Winter Weight" Oil if
Necessary
In some climates it is recommended that a
lower viscosity "winter weight" oil be used dur-
ing cold weather. See Section 9 for recommen-
dations. If you aren’t sure what weight oil you
should use, consult your Hyundai dealer. tenance 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.
C160H01A-AATUse Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer sys-
tem from freezing, add an approved anti-freeze
solution in accordance with instructions on the
container. Window washer anti-freeze is avail-
able from Hyundai dealers and most auto parts
outlets. Do not use engine coolant or other
types of anti-freeze as these may damage the
finish.
C160F01F-AATCheck Spark Plugs and Ignition
System
Inspect your spark plugs as described in Sec-
tion 6 (See page 6-6) 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.
C160G01A-AATTo 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.

F060A01A-AATEXPLANATION OF SCHEDULED MAIN-
TENANCE ITEMS
F060M01A-AAT
o Engine Oil and Filter
The engine oil and filter should be changed at
the intervals specified in the maintenance sched-
ule. If the car is being driven in severe condi-
tions, more frequent oil and filter changes are
required.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emission
system and cause hard starting. If an exces-
sive amount of foreign matter accumulates in
the fuel tank, the filter may require replacement
more frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at the
connections. Fuel filters should be installed by
trained technicians.
F060B02A-AAT
o Drive Belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation and
replace if necessary. Drive belts should be
checked periodically for proper tension and
adjusted as necessary.
F060D01A-AATo Fuel Lines, Fuel Hoses and Connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Have a trained
technician replace any damaged or leaking parts
immediately.
F060G01A-AAT
o Vapor Hose and Fuel Filler CapThe vapor hose and fuel filler cap should be
inspected at those intervals specified in the
maintenance schedule. Make sure that a new
vapor hose or fuel filler cap is correctly re-
placed.
F060F01A-AATo Vacuum, Crankcase
Ventilation Hoses
Inspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and brit-
tle rubber, cracking, tears, cuts, abrasions, and
excessive swelling indicate deterioration. Par-
ticular attention should be paid to examine
those hose surfaces nearest to high heat sourc-
es, 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 moving component
which might cause heat damage or mechanical
wear. Inspect all hose connections, such as
clamps and couplings, 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.
F060H01A-AAT
o Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when filter is replaced.
F060J01A-AATo Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060E01A-AAT
o Timing beltInspect all parts related to the timing belt for
damage and deformation. Replace any dam-
aged parts immediately.
F070C01A-AAT
o CoolantThe coolant should be changed at the
intervals specified in the maintenance sched-
ule.
F070D01A-AAT
o Manual transaxle oilInspect the manual transaxle oil according to
the maintenance schedule.

G050C01A-AAT
To Check the Coolant Level
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "LOW" and "FULL"
lines on the reservoir when the engine is cold.
If the level is below the "LOW" mark, add
engine coolant to bring it up between "LOW"
and "FULL". If the level is low, inspect for
coolant leaks and recheck the fluid level fre-
quently. If the level drops again, visit your
Hyundai dealer for an inspection and diagnosis
of the reason.
G050D02A-AATTo Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow
all the engine coolant to drain from the
cooling system, then securely close the drain
cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer’s directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclockwise.
Now fill the radiator with clean demineral-
ized or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.5. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
WARNING:The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate 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 en-
gine coolant temperature decreases, the fan
will automatically shut off. This is a normal
condition.

G060B01GK-AAT
Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine per-
formance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plug, always use
the genuine parts recommended.

G060C01GK-GETChanging the Spark Plugs
G060C01GK
You will find it easier to change spark plugs if
the engine is cold. Always change one spark
plug at a time. This helps avoid getting the wires
mixed up.
1. Remove the center (2.0 L) cover on the
engine rocker cover.
NOTE:It is recommended that the spark plugs (For
2.7L Engines) should be changed by an
authorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when
the spark plug is removed.
3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.

TER
To change the filter, unsnap the clips around
the cover. When this is done, the cover can be
lifted off, the old filter removed and the new filter
put in its place. Genuine Hyundai Replacement
Parts are recommended.
CAUTION:o Operating your vehicle without a proper
air filter in place can result in excessive
engine wear.
o Be careful that dust or dirt does not enter
the air intake, or damage may result.

NOTE:Spark plugs should be tightened firmly. Over-
tightening can damage the threads in the
aluminum cylinder head. Also, leaving them
too loose can cause the spark plug to get
very hot and possibly result in damage to
the engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.

The wiper blades should be carefully inspected
from time to time and cleaned to remove accu-
mulations of road film or other debris. To clean
the wiper blades and arms, use a clean sponge
or cloth with a mild soap or detergent and water.
If the wipers continue to streak or smear the
glass, replace them with Genuine Hyundai
Replacement Parts or their equivalent.
CAUTION:o Do not operate the wipers on dry glass.
This can result in more rapid wear of the
wiper blades and may scratch the glass.
o Keep the blade rubber out of contact
with petroleum products such as engine
oil, gasoline etc.
