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 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.C160K01A-AATCarry Emergency EquipmentDepending on the severity of the weather where
you drive your car, you should carry appropri-
ate 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.
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 instruc-
tions 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.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 tempo-
rarily 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.
C160E01A-AATChange to "Winter Weight" Oil if Neces-
saryIn 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.C160F01A-AATCheck Spark Plugs and Ignition SystemInspect your spark plugs as described in Sec-
tion 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 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.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
F060F01A-AATo Vacuum, Crankcase
Ventilation HosesInspect the surface of hoses for evidence of
heat and/or mechanical damage. Hard and
brittle rubber, cracking, tears, cuts, abrasions,
and excessive swelling indicate deterioration.
Particular attention should be paid to examine
those hose surfaces nearest to high heat
sources, 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.F060D01TB-AATo Fuel Lines, Fuel Hoses and
ConnectionsCheck the fuel lines, fuel hoses and connec-
tions for leakage and damage. Replace any
damaged or leaking parts immediately.
F060M01A-AATo Engine Oil and FilterThe 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-AATo Fuel FilterA 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.
F060G01A-AATo 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.F060H01A-AATo Air Cleaner FilterA Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.F060J01A-AATo Spark PlugsMake sure to install new spark plugs of the
correct heat range.F060N02E-AATo Valve ClearanceInspect excessive valve noise and/or engine
vibration and adjust if necessary. A qualified
technician should perform the operation.

5. Start the engine, top off the radiator with water
and then add engine coolant to the reservoir
until the level is between "L" and "F".
6. 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
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the cooling fan so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases, the fan will automatically shut off.
This is a normal condition.
SPARK PLUGS
G060B02E-AATReplacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance 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:o When replacing the spark plugs, genu-
ine Hyundai replacement parts are rec-
ommended.
o It is recommended that spark plugs be
changed by an authorized Hyundai
dealer.Recommended Spark Plugs:* 2.0L SULEV Only.CHAMPION

G060A02E-AATYour engine was originally equipped with plati-
num or iridium-tipped spark plugs.
Platinum or iridium-tipped spark plugs will last
longer than conventional type spark plugs and
can be identified by blue lines (platinum only) on
the ceramic shell.NOTE:Do not clean or regap platinum or iridium-
tipped spark plugs.

G060C01S-AATChanging the Spark PlugsYou 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 cover on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around 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.
HGK256
!
WARNING:
It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself.
4. When preparing to remove the spark plug,
guide the socket down over the spark plug,
being careful not to damage the ceramic
insulator.
5. To remove the spark plug, turn the wrench
handle in a counterclockwise direction.
6. To replace the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
NOTE:Spark plugs should be tightened firmly.
Over-tightening can damage the threads in
the aluminum cylinder head. Leaving them
too loose can cause the spark plugs 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.
