Vehicle Care 305 Engine • The engine oil and filter should be changed prior to storage, as used engine oil contain contaminates that may cause engine damage. • Start the engine every 15 days. Run at fast idle until it reaches normal operating temperature. • With your foot on the brake, shift through all the gears while the engine is running. Fuel system • Fill the fuel tank with high-quality fuel until the first automatic shutoff of the fuel pump nozzle. Note: During extended periods of vehicle storage (30 days or more), fuel may deteriorate due to oxidation. Add a quality gas stabilizer product to the vehicle fuel system whenever actual or expected storage periods exceed 30 days. Follow the instructions on the additive label. The vehicle should then be operated at idle speed to circulate the additive throughout the fuel system. Cooling system • Protect against freezing temperatures. • When removing vehicle from storage, check coolant fluid level. Confirm there are no cooling system leaks, and fluid is at the recommended level. Battery • Check and recharge as necessary. Keep connections clean. • If storing your vehicle for more than 30 days without recharging the battery, it may be advisable to disconnect the battery cables to ensure battery charge is maintained for quick starting. Note: If battery cables are disconnected, it will be necessary to reset memory features. Brakes • Make sure brakes and parking brake are fully released. Tires • Maintain recommended air pressure. 2013 Navigator (nav) Owners Guide gf, 1st Printing USA (fus)
