5ENGINE OIL
SG030A1-E 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 orwhenever the vehicle is refuelled, whichever occurs sooner.
In addition, it is imperative that only
an approved grade and specificationof oil is used to avoid the possibility of serious engine damage and prema-ture wear. The use of "budget price" oil is a false economy that must be avoided if the maximum reliability anduseful life is to be obtained from the vehicle.
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 Engine 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 equip-ment.
o Windscreen wiper and washer op-
eration.
o Horn operation.
o Warning lamp 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. DAILY OPERATING CHECKS
G030B02O-EAT Recommended Oil
1. Petrol Engine The engine oil quality should meet the following classification. API SJ, SL or ABOVE, ILSAC GF-3 or ABOVE The oil viscosity should be selected according to the operating environ- ment of the engine by means of thetable shown above. The engine oil recommendations are complete in themselves and the use of additivesis neither required nor recommended. The use of engine oil additives may result in invalidation of the vehiclewarranty.

Engine Oil Level
The engine oil level should be checked
with the engine at normal operating temperature and the vehicle parked upon level ground.
Prior to checking the level, the ve-
hicle should be allowed to stand forseveral minutes after the engine has been switched off to allow the oil todrain back to the sump. Withdraw the dipstick and wipe it with
a clean rag. Replace the dipstick fully and withdraw again when the oil level may be read from the stick.

HGK5004
1.6L/2.0L
2.7LNormal oil level is indicated when the
oil is present between the two marks on the stick. It is not necessary to add oil if the level is above the lower mark and in any case, oil must not beadded to the degree that the level exceeds the upper mark. Replace the dipstick fully after checking the level.
WARNING:
Be very careful not to touch the
radiator hose when checking the engine oil as it may be hot enough to burn you.
NOTE: SAE 5W-20 (5W-30), ILSAC GF-3 engine oil is preferred regardlessof regional option and engine varia- tion. If SAE 5W-20, ILSAC GF-3 engine oil is not available, sec-ondary recommended engine oil for corresponding temperature range can be used.

ENGINE OIL REPLENISHMENT
If the indicated oil level is at or below the lower mark of the dipstick, oilshould be added until the level is at or below the upper mark. 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 checkingthe level again, allow several minutes for the oil to drain into the sump. Replace the oil filler cap rotating it ina clockwise direction until tight.The quantity of oil required to raisethe level from the minimum to maxi- mum level is approximately 1 litre. 1.6L/2.0L
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 asfollows;
o Engine oil is used to lubricate pis-
tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of 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 during the combustion process.
