NOTE: It is imperative that vehicles fitted with an air conditioning system have a coolantconcentration of the recommended strengthat all times. The use of the air conditioningsystem when the cooling system is filledwith water only will result in the heatermatrix freezing and subsequently bursting.Diesel engine
Only ethylene glycol based coolant with a corrosion inhibitor suited to aluminium alloyengine components should be used in thecooling system. No further additives or inhibi- tors should be used. The coolant specific gravity should be checked as prescribed inthe maintenance schedule to ensure adequatefrost and corrosion protection. In addition, theengine coolant must be replaced at the speci-fied interval since the corrosion inhibitor prop-erties deteriorate with time. It is important to note that whilst an increase in the concentration of anti freeze gives anincrease in the level of frost protection, asolution which is in excess of 65% anti freezewill result in reduced frost protection andengine overheating. Therefore the recom-mended concentration of 50% should not beexceeded for general use. The use of methanol based anti freeze com- pounds may result in engine overheating andwill invalidate the vehicle warranty.

6. Start the engine with the radiator cap still
removed and continue to add coolant as the level decreases as air is expelled fromthe system. When the level remains con-stant, replace the radiator cap and replen-ish the coolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine coolant temperature and may sometimesoperate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fanblade. As the engine coolant temperaturedecreases, the fan will automatically shutoff. This is a normal condition.

AUTOMATIC TRANSAXLE FLUID
The automatic transaxle fluid level should be checked and changed at those intervals pre-scribed in the maintenance schedule. It is ofparamount importance that only the specifiedfluid is used when replenishing or changing thefluid. The use of other fluids may irreparablydamage the transaxle and invalidate the manu-facturers warranty. In addition the ingress of dirtor lint may prevent correct functioning of thetransaxle and care must be exercised to pre-vent the ingress of such matter. NOTE:
Automatic transaxle fluid is a red color. As driving distance increases, the fluid colorturns darkish red gradually. It is a normalcondition and you should not judge theneed to replace based upon the changingcolor.You must replace the automatic transaxlefluid in accordance with intervals specifiedin the vehicle maintenance schedule insection 5.
CAUTION:The transaxle on fluid level must bechecked with the engine running and atnormal operating temperature and there-fore care must be exercised to preventinjury occurring through contact withrotating or hot parts of the engine.
Ensure that the vehicle is parked on level
ground with the parking brake firmly appliedand the engine cool. Remove the level plugfrom the transaxle when lubricant should be-gin to drip from the level hole. If the level islow and no lubricant is seen to drip, add therequired quantity of lubricant and replace theplug.
