Engine Coolant, Windshield Washers Do not add any rust inhibitors or other additives to your vehicle's cooling system. They may not be compatible with the coolant or engine components. Windshield Washers Check the fluid level in the windshield washer reservoir at least monthly during normal use. If the washer fluid is low, a ''WASHER FLUID LOW'' message appears on the multi-information display. Fill the reservoir with a good-quality windshield washer fluid. This increases the cleaning capability and prevents freezing in cold weather. Maintenance RESERVE TANK 6. Pour coolant into the reserve tank. Fill it to halfway between the MAX and MIN marks. Put the cap back on the reserve tank. 7. Reinstall the lid. CONTINUED 463
