Do not add any straight antifreeze or water. We recommend you check the engine coolant level every time you refuel. Check the reserve tank first. If it is completely empty, also check the coolant level in the radiator. Add the engine coolant accordingly. 1 Engine Coolant NOTICE If temperatures consistently below −22°F (−30°C) are expected, the coolant mixture should be changed to a higher concentration. Consult a dealer for more information. If Honda antifreeze/coolant is not available, you may use another major brand non-silicate coolant as a temporary replacement. Check that it is a high quality coolant recommended for aluminum engines. Continued use of any non-Honda coolant can result in corrosion, causing the cooling system to malfunction or fail. Have the cooling system flushed and refilled with Honda antifreeze/coolant as soon as possible. Do not add rust inhibitors or other additives to your vehicle's cooling system. They may not be compatible with the coolant or with the engine components. ■ Reserve Tank Reserve Tank 1. Check the amount of coolant in the reserve tank. MAX 342 Maintenance MIN 2.
