SG020B1-E DAILY OPERATING CHECKSThe following items should be checked on a daily basis or whenever the vehicle is refuelled, which-ever occurs sooner.
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 operation.
o Horn operation.
o Warning lamp operation.
o Adjustment and cleanliness of mirrors.
o Seat and seat belt adjustment and operation.
o Fluid leakage. The vehicle must not be driven if the daily oper- ating checks indicate that any item of equipmentrelated to the safety or roadworthiness of thevehicle is not functioning correctly. SG030A1-E ENGINE OILThe correct engine oil level is of paramount importance. An excessively high or low oil levelmay result in irreparable damage being sus-tained by the engine. The engine oil level must bechecked on a daily basis or whenever the vehicleis refuelled, whichever occurs sooner.In addition, it is imperative that only an approvedgrade and specification of oil is used to avoid thepossibility of serious engine damage and prema-ture wear. The use of "budget price" oil is a falseeconomy that must be avoided if the maximumreliability and useful life is to be obtained from thevehicle.
SG030B02GK-E Recommended Oil A multi grade oil having a specification which meets A.P.I. specification of SH, SG or above isrecommended. The oil viscosity should be se-lected according to the operating environment ofthe engine by means of the table shown below.The engine oil recommendations are complete inthemselves and the use of additives is neitherrequired nor recommended. The use of engineoil additives may result in invalidation of thevehicle warranty.

OWNER MAINTENANCE
6-6 WARNING: The oil being drained from the engine will behot. Care should be exercised to preventscalding.
4. When the oil has drained from the sump,
replace the drain plug using a new washer ensuring that the plug is not over tightened.
Tightening torque :
4.5 ~ 4.0 kgf.m (1.6/2.0L)4.5 ~ 3.5 kgf.m (2.7L)
5. Remove the oil filter by rotating counterclock- wise, using a proprietary oil filter removal toolif necessary. Note that the oil filter will containapproximately 0.5 litres of oil and this shouldbe collected in a suitable receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotating clock-wise until the filter contacts the mounting andthen a further one half turn. Do not over-tighten. Tightening torque: 1.2 ~ 1.6 kgf.m.
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure that nooil leaks exist. Turn off the engine and after acouple minutes, recheck the oil level.
WARNING:Prolonged and repeated contact with usedengine oils may result in serious skin disor-ders including dermatitis and cancer. Avoidcontact with skin as far as possible and al-
G040A02GK-EAT ENGINE OIL AND FILTER REPLACEMENT The engine oil and filter must be changed at the time or mileage interval specified in the mainte-nance schedule. If the vehicle is operated undersevere or adverse conditions, the oil and filtermust be replaced more frequently.To replace the oil and filter, proceed as follows:
1. Ensure that the engine is at normal operating
temperature and park the vehicle on level ground with the parking brake securely ap-plied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.
3. Prepare a suitable receptacle to collect the displaced oil and remove the drain plug fromthe sump.
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 normal driving. The cause of oilconsumption in a normal engine are as follows;
o Engine oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is left on the cylinder wall whena piston moves downwards in the cylinder.High negative pressure generated during en-gine operation sucks some of the oil into thecombustion chamber.This oil with some oil of the cylinder wall isburned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc.More engine oil may be consumed undersevere driving conditions such as high speeds,frequent acceleration and deceleration, com-pared to normal driving.

G290A01GK-EAT HEADLIGHT AIMING ADJUSTMENT
Before performing aiming adjustment, make sure of the following.
1. Keep all tyres inflated to the correct pressure.
2. Place the vehicle on level ground and press
the front bumper & rear bumper down severaltimes. Place vehicle at a distance of 118.1 in.(3m) from the test wall.
3. See that the vehicle is unloaded (except for full levels of coolant, engine oil and fuel, andspare tyres, jack, and tools).
4. Clean the head lights lens and turn on the headlight.
5. Open the bonnet.
6. Draw the vertical line (through the centre of each headlight beam pattern) and the hori-zontal line (through the centre of each head-light beam pattern) on the aiming screen.And then, draw a parallel line at 1.18 in. (30mm) under the horizontal line.
WARNING:The halogen bulb contains gas under pres-sure and if impacted could shatter, resultingin flying fragments. Always wear eye protec-tion when servicing the bulb. Protect the bulbagainst abrasions or scratches and againstliquids when lighted. Turn on the bulb onlywhen installed in a headlight. Replace theheadlight if damaged or cracked. Keep thebulb out of the reach of children and disposeof the used bulb with care.
