C160J01A-AATDon'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.
C160I01A-AATDon't Let Your Parking Brake Freeze
Under 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.
C160H01A-AATUse Approved Anti-Freeze in Window
Washer System
To keep the water in the window washer system
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.
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. Handle the
heated key with care to avoid burning the
fingers.
C160F01A-AAT
Check Spark Plugs and Ignition
System
Inspect 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.
C160D01A-AATCheck Battery and Cables
Winter 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.
C160E01A-AAT
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 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160C01A-AATUse High Quality Ethylene Glycol
Coolant
Your 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 cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
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.

VEHICLE MAINTENANCE REQUIREMENTS 5- 7
F060G01A-AATo Vapor Hose and Fuel Filler Cap
The 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.
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.
F060A01A-AATEXPLANATION OF SCHEDULED MAIN-
TENANCE ITEMS
F060B01A-AATo 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.
F060M01A-AATo 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-AATo 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.
F060F01A-AATo Vacuum, Crankcase
Ventilation Hoses
Inspect 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.
F070C01A-AATo Coolant
The coolant should be changed at the intervals
specified in the maintenance schedule.
F060E01A-AATo Timing belt
Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-
aged parts immediately.
F060J01A-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060H01A-AATo Air cleaner filter
A Genuine Hyundai air cleaner filter is recom-
mended when the filter is replaced.

G060A01O-AATSPARK PLUGS
Your engine was originally equipped with plati-
num-tipped spark plugs.
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.
G060B02O-AATReplacing the Spark Plugs
The 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 the spark plug
should be changed by an authorized
Hyundai dealer. (2.7 L, 3.5 L)

water and then add 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 coolant 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.

G060C0IO-AATChanging the Spark Plugs
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 cover (2.4 L) on the
engine rocker cover.
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.
G060C01O
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.
NOTE:Spark plugs should be tightened to speci-
fication. 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. 4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insu lator.
5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.
6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
