engine and ensure that no oil leaks exist. Turn off the engine and aftera couple minutes, recheck the oil level.
CAUTION:
Slowly pour the recommended oil by using a funnel. Do not overfill to prevent engine damage.
WARNING:
Prolonged and repeated contact withused engine oils may result in seri- ous skin disorders including der-matitis and cancer. Avoid contact with skin as far as possible and always wash thoroughly after anycontact. Keep used oils out of reach of children. It is illegal to pollute drains, water courses and soil. Useonly authorisedwaste collection fa- cilities including civic amenity sites and garages for the disposalof used oil and oil filters. If in doubt, contact the local authority for dis- posal instructions. WARNING:
Do not remove the radiator cap when
the engine is hot, since the system is pressurised and coolant may be ejected from the radiator resultingin scalding.

Coolant recommendations
Only ethylene glycol based coolant
with a corrosion inhibitor suited toaluminium alloy engine componentsshould be used in the cooling system. No further additives or inhibitors should be used. The coolant specificgravity should be checked as pre- scribed in the maintenance schedule to ensure adequate frost and corro-sion protection. In addition, the en- gine coolant must be replaced at the specified interval since the corrosioninhibitor properties deteriorate with time.
ENGINE COOLANT CHECK- ING AND REPLACING

! It is important to note that whilst an increase in the concentration of antifreeze gives an increase in the level of frost protection, a solution which is in excess of 65% anti freeze will resultin reduced frost protection and engine overheating. Therefore the recom- mended concentration of 50% shouldnot be exceeded for general use.The use of methanol based anti freezecompounds may result in engine over-heating and will invalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an air conditioning systemhave a coolant concentration of the recommended strength at all times. The use of the air condition-ing system when the cooling sys- tem is filled with water only will result in the heater matrix freezingand subsequently bursting.
