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.
Miscellaneous
• Make sure all linkages, cables, levers and pins under vehicle are
covered with grease to prevent rust.
• Move vehicles at least 25 ft (8 m) every 15 days to lubricate working
parts and prevent corrosion.
