PREPARING YOUR VEHICLE
FOR STORAGE
If you plan on storing your vehicle for 30
days or more, the following maintenance
recommendations ensures your vehicle
stays in good operating condition.
Under various conditions, long-term
storage may lead to degraded engine
performance or failure unless you use
specific precautions to preserve your
vehicle.
General
•
Store all vehicles in a dry, ventilated
place.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and weather damage.
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminants which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running. Body
•
Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housings
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Hybrid Battery Systems
We recommend the following actions for
your vehicle:
• When storing your vehicle for greater
than 30 days the state of charge
should be approximately 50%.
Additionally we recommend
disconnecting the 12V battery which
will reduce system loads on the HV
battery.
12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
Note: It is necessary to reset memory
features if you disconnect the battery
cables.
Brakes
Make sure the brakes and parking brake
release fully.
