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. G030B05HP-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.
2. Diesel Engine
(1) Select engine oil of the proper SAE viscosity number according to the atmospheric temperature. Recommended viscosity is given in the following illustration.

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 givenin the following illustration.
(2) A multi grade oil having a specifi- cation which meets A.P.I. specifi-cation of SG, SH or ABOVE isrecommended.DAILY OPERATING CHECKS
SG020B1-E The following items should be checked on a daily basis or whenever the vehicle is refuelled, whichever occurssooner.
o Engine oil level.
o Coolant level.
o Power steering fluid level.
o Brake fluid level.
o Windscreen washer fluid level.
o Battery condition.
o Tyre condition and pressures.
o Operation and cleanliness of all lighting equipment.
o Windscreen wiper and washer op-
eration.
o Horn operation.
o Warning light operation.
o Adjustment and cleanliness of mir- rors.
o Seat and seat belt adjustment and operation.
o Fluid leakage. The vehicle must not be driven if the daily operating checks indicate that any item of equipment related to the safety or roadworthiness of the ve-hicle is not functioning correctly.ENGINE OIL
G030A01FC-EAT The correct engine oil level is of para-
mount importance. An excessively high or low oil level may result inirreparable damage being sustained by the engine. The engine oil level must be checked on a daily basis,whenever the vehicle is refuelled or before starting a long trip, whichever occurs sooner.
In addition, it is imperative that only
an approved grade and specificationof oil is used to avoid the possibility ofserious engine damage and prema- ture wear. The use of "budget price" oil is a false economy that must beavoided if the maximum reliability and useful life is to be obtained from the vehicle.

The oil viscosity should be selected according 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 addi- tives is neither required nor recom- mended. The use of engine oil addi-tives may result in invalidation of the vehicle warranty.
NOTE: The use of a 5W-20 multi grade oil is not recommended for sustained highspeed use. 2. Diesel Engine
(1) Select engine oil of the proper SAE
viscosity number according to the atmospheric temperature. Recommended viscosity is given in the following illustration.
NOTE: SAE 5W-30 oil should be used only
in areas where extremely cold tem- peratures of 50°F(10°C) or below areexperienced. If the atmospheric temperatures are32°F (0°C) or below, SAE #30 oilmust not be used. This oil should be used only in areas where the atmospheric temperatures are 32°F(0°C) or above. (2) The engine oil quality should meet

the following classification: API: CF-4 or ABOVE ACEA: B4 or ABOVE

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).
WARNING:
Be very careful not to touch theradiator hose when adding the en- gine oil as it may be hot enough to burn you.
