DRIVING YOUR HYUNDAI 2- 11
C160C01A-AAT Use High Quality Ethylene Glycol Coolant Your Hyundai is delivered with high quality ethyl- ene glycol coolant in the cooling system. It is the only type of coolant that should be used because it helps prevent corrosion in the cooling system, lubricates the water pump and prevents freezing. Be sure to replace or replenish your coolant in accordance with the maintenance schedule in Section 5. Before winter, have your coolant test- ed to assure that its freezing point is sufficient for the temperatures anticipated during the winter. C160D01A-AAT Check 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.
C160G01A-GAT To Keep Locks from Freezing To keep the locks from freezing, squirt an ap- proved 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 your fin- gers. NOTE: The proper temperature for using the immo- bilizer key is from -40°C to 80°C. If you heat the immobilizer key over 80°C to open the frozen lock, it may cause damage to the transponder in its head.
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. C160F01A-AAT Check Spark Plugs and Ignition System Inspect your spark plugs as described in Section 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.
C160H01A-AAT Use Approved Anti-Freeze in Window Washer System To keep the water in the window washer system from freezing, add an approved anti-freeze solu- tion in accordance with instructions on the con- tainer. Window washer anti-freeze is available from Hyundai dealers and most auto parts out- lets. Do not use engine coolant or other types of anti-freeze as these may damage the finish. C160I01A-AAT Don’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 temporarily 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. C160J01A-AAT Don’t Let Ice and Snow Accumulate Underneath Under some conditions, snow and ice can build up under the fenders and interfere with the steer- ing. When driving in severe winter conditions where this may happen, you should periodically check underneath the car to be sure the move- ment of the front wheels and the steering compo- nents is not obstructed.
deceleration, use engine braking to the fullestextent. Sudden brake applications on snowy or icy roads may cause skids to occur. You need to keep 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 provinces. Check province laws before fitting tire chains.

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 demineralized or distilled water. Continue to add clean deminer-alized or distilled water in small quantities untilthe fluid level stays up in the radiator neck. G060B02S-GAT
REPLACING THE SPARK PLUGS The spark plugs should be changed at theintervals specified in the vehicle maintenancesschedule 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 plugs, genuine Hyundai replacement parts are recom-mended. Recommended Spark Plugs:
SSA6060A
Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)

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.

NOTE: Spark plugs should be tightened firmly. Over- tightening can damage the threads in thealuminum cylinder head. Leaving them tooloose can cause the spark plugs to get veryhot and possibly result in damage to theengine.
7. 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.
SSA6061ASSA6062A
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 old spark plug, guide the socket down over the spark plug, being careful not to damage the ce-ramic insulator.
5. To remove the spark plug, turn the wrench handle in a counterclockwise direction.
6. To install the new spark plug, guide the socket down over the spark plug, beingcareful not to damage the ceramic insulator.
G060C01S-GAT
Changing the Spark Plugs
You will find it easier to change spark plugs if
the engine is cold. Always change one sparkplug at a time. This helps avoid getting the wiresmixed 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 sparkplug 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 carboncore conductor.
