2- 16 DRIVING YOUR HYUNDAI
C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 6 and replace them if neces-sary. Also check all ignition wiring andcomponents to be sure they are notcracked, worn or damaged in any way. C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an approved de-icer fluid or glycerineinto the key opening. If a lock is cov-ered with ice, squirt it with an approvedde-icing fluid to remove the ice. If the lock is frozen internally, you may be able to thaw it out by using a heatedkey. Handle the heated key with careto avoid burning your fingers. NOTE: The proper temperature for using the immobilizer key is from -40°C to 80°C. If you heat the immobilizerkey over 80°C to open the frozenlock, it may cause damage to thetransponder in its head.
C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethylene glycol coolant in thecooling system. It is the only type of coolant that should be used because it helps prevent corrosion in the coolingsystem, lubricates the water pump andprevents freezing. Be sure to replaceor replenish your coolant in accor-dance with the maintenance schedule in Section 5. Before winter, have your coolant tested to assure that its freez-ing point is sufficient for the tempera-tures anticipated during the winter. C160D01A-AAT Check Battery and Cables Winter puts additional burdens on the battery system. Visually inspect thebattery and cables as described inSection 6. The level of charge in yourbattery can be checked by your Hyun- dai 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 during cold weather. See Section 9 for recommendations. If you aren't sure what weight oil you shoulduse, consult your Hyundai dealer.
noted that installing tire chains on thetire will provide a greater driving force,but will not prevent side skids. NOTE: Tire chains are not legal in all prov- inces. Check province laws before fitting tire chains.

5- 8 VEHICLE MAINTENANCE REQUIREMENTS
F060H01A-AAT
o Air Cleaner Filter A Genuine Hyundai air cleaner filter is recommended when the filter is re-placed. F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070C02A-AAT
o Coolant The coolant should be changed at the intervals specified in the mainte-nance schedule. F070D01A-AAT
o Manual Transaxle Oil Inspect the manual transaxle oil ac- cording to the maintenance schedule. NOTE: If the oil level is low, check for possible leaks before adding oil. Do not overfill. F070E03A-AAT
o Automatic Transaxle Fluid and
Filter
The fluid level should be in the "HOT"range of the dipstick, after the engineand transaxle are at normal operatingtemperature. Check the automatic transaxle fluid level with the engine running and the transaxle in neutral,with the parking brake properly ap-
plied. Use DIAMOND ATF SP-III or
SK ATF SP-III when adding or chang-ing fluid. F070F01A-AAT
o Brake Hoses and Lines
Visually check for proper installation, chafing, cracks, deterioration and any leakage. Replace any deteriorated ordamaged parts immediately. F070G02A-AAT
o Brake Fluid
Check brake fluid level in the brake fluid reservoir. The level should bebetween "MIN" and "MAX" marks onthe side of the reservoir. Use onlyhydraulic brake fluid conforming toDOT 3 or DOT 4. F070H01A-AAT
o Rear Brake Drums/Linings,
Parking Brake
Check the rear brake drums and lin-ings for scoring, burning, leaking fluid,broken parts, and excessive wear.Inspect the parking brake system in- cluding the parking brake lever and cables. For detailed service proce-dures, refer to the Shop Manual. F070J01A-AAT
o Brake Pads, Calipers and
Rotors
Check the pads for excessive wear, discs for run out and wear, and cali- pers for fluid leakage. F070K01A-AAT
o Exhaust Pipe and Muffler
Visually inspect the exhaust pipes, muffler and hangers for cracks, dete-rioration, or damage. Start the engineand listen carefully for any exhaust gas leakage. Tighten connections or replace parts as necessary.

SPARK PLUGS
Your engine was originally equipped
with platinum-tipped spark plugs. (If installed)
Platinum-tipped spark plugs will last
longer than conventional type sparkplugs and can be identified by blue lines on the ceramic shell.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

Replacing the Spark Plugs
The spark plugs should be changed
at the intervals specified in the ve- hicle maintenance schedule in Sec- tion 5 or whenever engine perfor- mance indicates they should bechanged. Symptoms that suggest poor spark plug performance include en- gine misfiring under load, loss of fueleconomy, poor acceleration, etc. When spark plugs are replaced, al- ways use spark plugs recommendedby Hyundai. The use of other spark plugs can result in loss of perfor- mance, radio interference or enginedamage.
NOTE:
o When replacing the spark plug, Genuine Hyundai ReplacementParts are recommended. Recommended Spark Plugs:
NOTE: Do not clean or regap platinum- tipped spark plugs.
o Spark plugs should be tightenedfirmly. Overtightening can dam- age the threads in the aluminum cylinder head. Also, leavingthem too loose can cause the spark plug to get very hot and posibly result in damage to theengine.
o It is recommended that the spark plug should be changed by anauthorized Hyundai dealer.
