VEHICLE STORAGE
If you plan on storing your vehicle for an extended period of time
(30 days or more), refer to the following maintenance recommendations
to ensure your vehicle stays in good operating condition.
All motor vehicles and their components were engineered and tested for
reliable, regular driving. Long term storage under various conditions may
lead to component degradation or failure unless specific precautions are
taken to preserve the components.
General
• Store all vehicles in a dry, ventilated place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they require regular maintenance to
protect against rust and damage.
Body
• Wash vehicle thoroughly to remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing and underside of front fenders.
See the Cleaning chapter for more information.
• Periodically wash vehicles stored in exposed locations.
• Touch-up raw 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 the vehicle is
washed. See the Cleaning chapter for more information.
• Lubricate all hood, door and trunk lid hinges, and latches with a light
grade oil. See the Cleaning chapter for more information.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and solvents.
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.
