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 and components to be sure they are not cracked, worn or damaged in any way.
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 used because ithelps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replaceor replenish your coolant in accor- dance with the maintenance schedule in Section 5. Before winter, have yourcoolant 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 in Section 6. The level of charge in your battery can be checked by your Hyun-dai 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. SeeSection 9 for recommendations. If you aren't sure what weight oil you should use, consult your Hyundai dealer.
C160A01A-AAT WINTER DRIVING The more severe weather conditions of winter result in greater wear andother problems. To minimize the prob- lems of winter driving, you should fol- low these suggestions: C160B01A-GAT Snowy or Icy Conditions To drive your vehicle in deep snow, it may be necessary to use snow tires or to install tire chains on your tires. If snow tires are needed, it is necessaryto select tires equivalent in size and type of the original equipment tires. Failure to do so may adversely affectthe safety and handling of your car. Furthermore, speeding, rapid accel- eration, sudden brake applications, andsharp turns are potentially very haz- ardous practices. During deceleration, use engine brak-ing to the fullest extent. Sudden brake applications on snowy or icy roads may cause skids to occur. You need tokeep sufficient distance between the vehicle in front and your vehicle. Also, apply the brake gently. It should be noted that installing tire chains on the tire 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 beforefitting tire chains.

3- 2 WHAT TO DO IN AN EMERGENCY
D010A01A-AAT IF THE ENGINE WILL NOT START
WARNING:
If the engine will not start, do not push or pull the car to start it. Thiscould result in a collision or cause other damage. In addition, push or pull starting may cause the cata-lytic converter to be overloaded and create a fire hazard. D010B01A-AAT If Engine Doesn't Turn Over or Turns Over Slowly 1. If your car has an automatic
transaxle, be sure the gear selector lever is in "N" or "P" and the emer-gency brake is set.
2. Check the battery connections to be
sure they are clean and tight.
3. Turn on the interior light. If the light dims or goes out when you operatethe starter, the battery is discharged.
4. Check the starter connections to be sure they are securely tightened.
5. Do not push or pull the vehicle to start it. See instructions for "Jump Starting" on the following pages. D010D01A-AAT If Engine Stalls While Driving
1. Reduce your speed gradually, keep-
ing a straight line. Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try to start the engine again. If your
vehicle will not start, contact a Hyundai dealer or seek other quali- fied assistance.
D010C01Y-AAT If Engine Turns Over Normally but Does Not Start
1. Check fuel level.
2. With the key in the off position, check all connectors at ignition, coils and spark plugs. Reconnect any that may be disconnected or loose.
3. Check the fuel line in the engine room.
4. If engine still refuses to start, call a
Hyundai dealer or seek other quali- fied assistance.

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 forpossible 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 engine and transaxle are at normal operatingtemperature.

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 or damaged parts immediately. F070G02A-AAT
o Brake Fluid
Check brake fluid level in the brake fluid reservoir. The level should be between "MIN" and "MAX" marks on the side of the reservoir. Use onlyhydraulic brake fluid conforming to DOT 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.
F070B01A-GAT
o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.

4. Turn the radiator cap counterclock-
wise without pressing down on it, until it stops. This relieves any pres-sure remaining in the cooling sys- tem. And remove the radiator cap by pushing down and turning coun-terclockwise.Now fill the radiator with clean dem-ineralized or distilled water.

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 possibly result in damage to theengine.
o It is recommended that spark
plugs be changed by an autho-rized Hyundai dealer.
