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.

6CHECKING THE ENGINE OIL
G030A01A-AAT Engine oil is essential to the perfor- mance and service of the engine. It is suggested that you check the oil levelat least once a week in normal use and more often if you are on a trip or driving in severe conditions. G030B06HP-GAT
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.

NOTE: For diesel-powered vehicle SAE 0W-
30 oil should be used only in areas where extremely cold temperatures of 10°C(50°F) or below are experi- enced.
(2) The engine oil quality should meet the following API classification:Diesel Engine (2.5 TCI) : CF-4 or ABOVE Diesel Engine (2.9 CRDi) : CF-4 or ABOVE
(3) The engine oil quality should meet the following ACEA classification :
Diesel Engine (2.5 TCI) : B2 or B3Diesel Engine (2.9 CRDi) : B4 orABOVE G030C02HP-AAT To Check the Oil Level Before checking the oil, warm up the engine to the normal operating tem- perature and be sure your car is parked on level ground. Turn the en-gine off. NOTE: Before checking or adding the en- gine oil, remove the cover abovethe engine oil filler cap and the engine oil level dipstick with a blade screwdriver inserted in thenotch (2.5 TCI only).

If the oil level is close to or below the "L" mark, add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counterclockwise.
2. Add oil, then check the level again.
Do not overfill.
3. Replace the cap by turning it clock-
wise.
The distance between the "F" and "L"marks is equal to about 1 liter (Gaso- line Engine/Diesel Engine (2.5 TCI))/ 1.4 liters (Diesel Engine (2.9 CRDi))of oil. 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 overfill not 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.

Recommended Oil
1. Petrol Engine
(1) Select engine oil of the proper SAE
viscosity number according to the atmospheric temperature. Recommended viscosity is given in the following illustration. The oil viscosity should be selectedaccording to the operating environ-ment of the engine by means of the table shown above. The engine oil recommendations are complete inthemselves and the use of additives is neither required nor recommended. The use of engine oil additives may resultin invalidation of the vehicle warranty. NOTE:
o SAE 5W-20 (5W-30), ILSAC GF-3
engine oil is preferred regardless of regional option and enginevariation.
o If SAE 5W-20, ILSAC GF-3 engine
oil is not available, secondaryrecommended engine oil for cor- responding temperature range can be used.
(2) The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE

!WARNING:
o Performing maintenance work on a vehicle can be dangerous. You can be seriously injured whilst performing some maintenanceprocedures. If you lack sufficient knowledge and experience or the proper tools and equipment to dothe work, have it done by Hyundai authorised repairer.
o Working under the bonnet with the engine running is dangerous. It becomes even more dangerouswhen you wear jewellery or loose clothing. These can become en- tangled in moving parts and re-sult in injury. Therefore, if you must run the engine whilst work- ing under the bonnet, make cer-tain that you remove all jewellery (especially rings, bracelets, watches, and necklaces) and allneckties, scarves, and similar loose clothing before getting near the engine or cooling fans.

Engine Oil Level
The engine oil level should be checked with the engine at normal operating temperature and the vehicle parkedupon level ground. Prior to checking the level, the vehicle
should be allowed to stand for severalminutes after the engine has been switched off to allow the oil to drain back to the sump.
Withdraw the dipstick and wipe it with
a clean rag. Replace the dipstick fullyand withdraw again when the oil levelmay be read from the dipstick. Normal oil level is indicated when the oil is present between the two marks on thedipstick. It is not necessary to add oil if the level is above the lower mark and in any case, oil must not be added tothe degree that the level exceeds the upper mark. Replace the dipstick fully after checking the level.

To add oil to the engine, remove the filler cap by rotating in an counter-clockwise direction and pour engine oil into the engine. Before checking the level again, allow several minutesfor the oil to drain into the sump. Replace the oil filler cap rotating it in a clockwise direction until tight. The quantity of oil required to raise the level from the minimum to maximum level is approximately 1 litre (PetrolEngine)/1.4 litres (Diesel Engine).
