Use Approved Anti-Freeze in Window Washer System
To keep the water in the window washer sys- tem from freezing, add an approved anti-freezesolution in accordance with instructions on thecontainer. Window washer anti-freeze is avail-able from Hyundai dealers and most auto partsoutlets. Do not use engine coolant or othertypes of anti-freeze as these may damage thefinish. C160I01X-GAT
Don't Let Your Parking Brake Freeze Under some conditions your parking brake can freeze in the engaged position. This is mostlikely to happen when there is an accumulationof snow or ice around or near the rear brakes orif the brakes are wet. If there is a risk theparking brake may freeze, apply it only tempo-

Check Spark Plugs and Ignition System
Inspect your spark plugs as described in Sec- tion 6 and replace them if necessary. Alsocheck all ignition wiring and components to besure they are not cracked, worn or damaged inany way.
C160D01A-AAT
Check Battery and Cables
Winter puts additional burdens on the batterysystem. Visually inspect the battery and cablesas described in Section 6. The level of chargein your battery can be checked by your Hyundaidealer 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 dur-ing cold weather. See Section 9 for recommen-dations. If you aren't sure what weight oil youshould use, consult your Hyundai dealer. C160G01A-GAT
To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerine into the keyopening. If a lock is covered with ice, squirt itwith an approved de-icing fluid to remove the
Failure to do so may adversely affect the safety
and handling of your car. Speeding, rapid accel-eration, sudden brake applications, and sharpturns are potentially very hazardous practices.During deceleration, use engine braking to thefullest extent. Sudden brake applications onsnowy or icy roads may cause skids to occur.
You need to keep sufficient distance betweenthe vehicle in front and your vehicle. Also, applythe brake gently.
It should be noted that installing tire chains on
the tire will provide a greater driving force, butwill not prevent side skids.
NOTE: Tire chains are not legal in all provinces.
Check province laws before fitting tire chains.
C160C01A-AAT
Use 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 usedbecause it helps prevent corrosion in the cool-ing system, lubricates the water pump andprevents 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 itsfreezing point is sufficient for the temperaturesanticipated during the winter.

EXPLANATION 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 arerequired.
F060B01A-AAT
o Drive belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil and replace ifnecessary. Drive belts should be checked pe-
riodically for proper tension and adjusted asnecessary.
F060C01A-GAT
o Fuel filter
A clogged filter can limit the speed at which the
vehicle may be driven, damage the emissionsystem and cause hard starting. If an exces-sive amount of foreign matter accumulates inthe fuel tank, the filter may require replacementmore frequently.
After installing a new filter, run the engine for
several minutes, and check for leaks at theconnections. F060D01A-GAT
o Fuel lines, fuel hoses and connec-
tions
Check the fuel lines, fuel hoses and connec-
tions for leakage and damage. Replace anydamaged or leaking parts immediately. Inspect the hose routing to assure that the
hoses do not come in contact with any heatsource, sharp edges or moving component
which might cause heat damage or mechanicalwear. Inspect all hose connections, such as
clamps and couplings, to make sure they aresecure, 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-AAT
o Spark plugs
Make sure to install new spark plugs of the
correct heat range.
F060E01A-AAT
o Timing belt Inspect all parts related to the timing belt for
damage and deformation. Replace any dam-aged parts immediately.
F060G01A-AAT
o Vapor hose and fuel filler cap The vapor hose and fuel filler cap should be
inspected at those intervals specified in themaintenance schedule. Make sure that a newvapor hose or fuel filler cap is correctly re-placed.
F060F01A-AAT
o Vacuum, crankcase ventilation hos-
es
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 examinethose hose surfaces nearest to high heat sourc-es, such as the exhaust manifold. F060N01X-GAT
o Valve clearances Incorrect valve clearance will not only result in
unsteady engine operation, but will also causeexcessive noise and reduced engine perfor-
mance. Inspect valve clearance and adjust asrequired while the engine is hot.
Valve-to-rocker arm clearance Intake valves ..... 0.2 mm (0.008 in.)Exhaust valves .... 0.25 mm (0.010 in.)

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 bypushing down and turning counterclockwise. Now fill the radiator with clean demineral- ized or distilled water. Continue to add cleandemineralized or distilled water in small quan-tities until the fluid level stays up in theradiator neck.SSA6060A

REPLACING THE SPARK PLUGS
The 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, lossof fuel economy, poor acceleration, etc. Whenspark plugs are replaced, always use sparkplugs recommended by Hyundai. The use ofother 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.

5. Start the engine, top off the radiator with water and then add engine coolant to the reservoir until the level is between "LOW"and "FULL".
6. Replace the radiator and reservoir caps and check to be sure the drain cocks are fullyclosed 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 theblades of the cooling fan so that you are notinjured by a rotating fan blade. As the en-gine coolant temperature decreases, the fanwill automatically shut off. This is a normalcondition.

6-8 NOTE: Spark plugs should be tightened firmly. Over- tightening can damage the threads in thealuminum cylinder head. Also, leaving them
too loose can cause the spark plug to getvery hot and possibly result in damage tothe engine.
6. Replace the cable by pushing the insulated connector directly down onto the electrode.Check to be sure it has snapped into placeand can't fall off.

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 wiresmixed up.
1. Using a clean cloth, remove any dirt that has accumulated around the base of the spark plug so it cannot fall into the cylinder whenthe spark plug is removed. WARNING: It is recommended that the engine be cool
or cold when changing the spark plugs. If the engine is hot, you could burn yourselfon the insulated connector, the spark plugor the engine itself.
3. When preparing to remove the old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
4. To remove the old spark plug, turn the wrench handle in a counterclockwise direc-tion.
5. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator.
