Start the engine, and then let it idle for several minutes while checking it for oil leakage. If oil is leaking, immediately turn the engine off and check for the cause. NOTE: After the engine is started, the engine oil level warning light should go off if the oil level is sufficient. _ _ EC000067 1. Minimum level mark EAU04298 NOTE: G The coolant level must be checked on a cold engine since the level varies with engine temperature. G Make sure that the motorcycle is positioned straight up when checking the coolant level. A slight tilt to the side can result in a false reading. _ _ CAUTION: If the oil level warning light flickers or remains on, immediately turn the engine off and have a Yamaha dealer check the vehicle. _ _ 2. Check the coolant level in the coolant reservoir. NOTE: The coolant should be between the minimum and maximum level marks. _ _ Coolant The coolant level should be checked before each ride. In addition, the coolant must be changed at the intervals specified in the periodic maintenance and lubrication chart.

Do not use hard water or salt water since it is harmful to the engine. G If water has been used instead of coolant, replace it with coolant as soon as possible, otherwise the engine may not be sufficiently cooled and the cooling system will not be protected against frost and corrosion. G If water has been added to the coolant, have a Yamaha dealer check the antifreeze content of the coolant as soon as possible, otherwise the effectiveness of the coolant will be reduced. _ 14.

If necessary, add sufficient coolant until it reaches the top of the radiator, and then install the radiator cap. Check the coolant level in the reservoir. If necessary, remove the coolant reservoir cap, add coolant to the maximum level mark, and then install the cap. Start the engine, and then check the vehicle for coolant leakage.
