Maintenance Vacuum crankcase ventilation hoses Inspect the surface of hoses for evidence of heat and/or mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Particular attention should be paid to examine those hose surfaces nearest to high heat sources, such as the exhaust manifold. Inspect the hose routing to assure that the hoses do not come in contact with any heat source, sharp edges or moving component which might cause heat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidence of deterioration or damage. Air cleaner filter A Genuine HYUNDAI air cleaner filter is recommended when the filter is replaced. Coolant The coolant should be changed at the intervals specified in the maintenance schedule. Spark plugs Make sure to install new spark plugs of the correct heat range. Manual transaxle fluid (if equipped) Inspect the manual transaxle fluid according to the maintenance schedule. Valve clearance Inspect for excessive valve noise and/or engine vibration and adjust if necessary. An authorized HYUNDAI dealer should perform the operation. Automatic transaxle fluid (if equipped) Automatic transaxle fluid should not be checked under normal usage conditions. But in severe conditions, the fluid should be changed at an authorized HYUNDAI dealer in accordance to the scheduled maintenance at the beginning of this chapter. Cooling system Check for cooling system components, such as radiator, coolant reservoir, hoses and connections for leakage and damage. Replace any damaged parts. ✽ NOTICE Automatic transaxle fluid color is basically red. As the vehicle is driven, the automatic transaxle fluid will begin to look darker. It is normal condition and you should not judge the need to replace the fluid based upon the changed color. 7 19
