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 consump- tion 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 the cylinderwall when a piston moves down- wards in the cylinder. High negative pressure generated during engineoperation sucks some of the oil into the combustion chamber. This oil with some oil of the cylinderwall is burned by the high tempera-
ture combustion gases during the combustion process.
o The engine oil consumption is strongly effected by the viscosityand quality of oil, engine rpm anddriving condition etc. The engine oil is more consumed under severe driving conditions such as highspeeds and frequent acceleration and deceleration than normal driv- ing condition.
!
NOTE:
o It is recommended that the engine oil and filter should be changed by an authorized Hyundai dealer.
o Always dispose of used engine oil in an environmentally acceptablemanner. It is suggested that it beplaced in a sealed container and taken to a service station for recla- mation. Do not pour the oil on theground or put it into the house- hold trash.
WARNING:
Used motor oil may cause irritation or cancer of the skin if left in contact with the skin for prolonged periods of time. Wash your hands thoroughlywith soap and warm water as soon as possible after handling used oil. G050A01TG-AAT CHECKING THE ENGINE COOL- ANT
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 ifyou do not observe this precau- tion. Do not remove the radiator cap until the radiator is cool to thetouch.

NOTE: It is recommended that the engine coolant should be changed by an authorized Hyundai dealer.

5. Open the hood.
6. Draw the vertical line (through the
center of each headlight beam pat-tern) and the horizontal line (throughthe center of each headlight beam pattern) on the aiming screen. And then, draw the horizontal paral- lel line at 30 mm (1.18 in.) under the horizontal line.
7. Adjust each cut-off line of the low beam to the parallel line with a phillipsscrewdriver - VERTICAL AIMING.
8. Adjust each cut-off line of the low
beam to each vertical line with aphillips screwdriver - HORIZONTAL AIMING. HTB269

G290A01FC-GAT HEADLIGHT AIMING ADJUST- MENT Before performing aiming adjustment, make sure of the following.
1. Keep all tires inflated to the correct
pressure.
2. Place the vehicle on level ground and press the front bumper and rear bumper down several times. Place the vehicle at a distance of 3,000mm (118 in.) from the test wall.
3. See that the vehicle is unloaded
(except for full levels of coolant,engine oil and fuel, and spare tire, jack, and tools).
4. Clean the head lights lens and turn on the headlight (low beam).
