Check the coolant level in the pressurized coolant reservoir. Adjust the level so that the fluid is between the MAX and MIN markings. For the coolant, use genuine NISSAN Long Life coolant. (On delivery of new vehicle, the reservoir is filled to the MIN level. Be sure to replenish approximately 0.3 to 0.4 US quart (0.3 to 0.4 liter) of coolant.)
