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. C160G02A-GAT To 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 cov-ered with ice, squirt it with an approved de-icing fluid to remove the ice. If the lock is frozen internally, you may beable to thaw it out by using a heated key. Handle the heated key with care to avoid injury. NOTE: The proper temperature for using the immobilizer key is from -40°C (-40°F) to 80°C (176°F). If you heatthe immobilizer key over 80°C (176°F) to open the frozen lock, it may cause damage to the transpon-der in its head.
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 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 during cold weather. See Section 9 for recommendations. If youaren't sure what weight oil you should use, consult your Hyundai dealer.
C160C01A-AAT Use High Quality Ethylene Gly- col 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 and prevents freezing. Be sure to replace or 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.

Recommended Oil 1. Gasoline Engine
(1) Select engine oil of the proper
SAE viscosity number according to the atmospheric temperature. Recommended viscosity is given in the following illustration.
(2) The engine oil quality should meet the following classification.
API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE NOTE:
o For good fuel economy, SAE 5W-20 (5W-30), ILSAC GF-3 en- gine oil is preferred regardless of regional option and engine variation.
o If SAE 5W-20, ILSAC GF-3 en- gine oil is not available, second-ary recommended engine oil forcorresponding temperature range can be used.

WARNING:
Do not remove the radiator cap when the engine is hot. When the engine is hot, the engine coolant is underpressure and may erupt through the opening if the cap is removed. You could be seriously burned if you donot observe this precaution. Do not remove the radiator cap until the radiator is cool to touch.
G350A01A-GAT ENGINE OIL CONSUMPTION Function of Engine Oil Engine oil has the primary function of lubricating and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should
consume some engine oil while nor- mal driving. The cause of oil con-sumption in a normal engine are as follows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on thecylinder wall when a piston movesdownwards in the cylinder. High negative pressure generated dur- ing engine operation sucks someof the oil into the combustion cham- ber. This oil with some oil of the cylin- der wall is burned by the high tem- perature combustion gases duringthe combustion process.
o The engine oil consumption is strongly effected by the viscosityand quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.

! CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfillnot to damage engine.
WARNING:
Be very careful not to touch the radiator hose when adding the en- gine oil as it may be hot enough toburn you.
