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

•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
When driving with the full-size dissimilar spare tire and wheel assembly,
additional caution should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
•Driving vehicles with a load on the cargo rack
Drive cautiously when using a full-size dissimilar spare tire and wheel,
and seek service as soon as possible.
Tire Change Procedure
WARNING:When one of the front wheels is off the ground, the
transmission alone will not prevent the vehicle from moving or
slipping off the jack, even if the vehicle is in P (Park) (automatic
transmission) or R (Reverse) (manual transmission).
WARNING:To help prevent the vehicle from moving when you
change a tire, be sure the parking brake is set, then block (in
both directions) the wheel that is diagonally opposite (other side and
end of the vehicle) to the tire being changed.
WARNING:If the vehicle slips off the jack, you or someone else
could be seriously injured.
WARNING:Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off the road to avoid
the danger of being hit when operating the jack or changing the wheel.
WARNING:To lessen the risk of personal injury, do not put any
part of your body under the vehicle while changing a tire. Do not
start the engine when your vehicle is on the jack. The jack is only
meant for changing the tire.
