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.

Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’
s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subsequent
vehicle start-ups as long as the malfunction
exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of
reasons, including the installation of
replacement or alternate tires or wheels on
the vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or
more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly. WARNING: Changes or modifications
not expressively approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
The term "IC:" before the radio certification
number only signifies that Industry Canada
technical specifications were met.
This device complies with Part 15 of the FCC
Rules and with License exempt RSS
Standards of Industry Canada. Operation is
subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference
received, including interference that may
cause undesired operation. TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS WARNING: The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to correctly
maintain tire pressures could increase the
risk of tire failure, loss of control, vehicle
rollover and personal injury. WARNING:
Do not use the tire
pressure displayed in the information
display as a tire pressure gauge. Failure to
follow this instruction could result in
personal injury or death.
Note: The use of tire sealants can damage
the tire pressure monitoring system.

WARNING: Park your vehicle so that
you do not obstruct the flow of traffic or
place yourself in any danger and set up a
warning triangle. WARNING:
Do not get under a
vehicle that is only supported by a vehicle
jack. 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:
Use only the specified
jacking points. If you use other positions,
you may damage the body, steering,
suspension, engine, braking system or the
fuel lines. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight, including
any vehicle cargo or modifications. If you
are unsure if the jack capacity is adequate,
contact the authorized dealer. WARNING:
The jack supplied with
this vehicle is only intended for changing
wheels. Do not use the vehicle jack other
than when you are changing a wheel in an
emergency. WARNING:
Make sure there is no
grease or oil on the threads or the surface
between the wheel lugs and nuts. This can
cause the lug nuts to loosen while driving. Note:
The jack does not require
maintenance or additional lubrication over
the service life of your vehicle.
Note: Passengers should not remain in your
vehicle when the vehicle is being jacked.
1. Park on a level surface, set the parking brake and activate the hazard flashers.
2. Place the transmission in park (P) and turn the engine off.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when you
sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
It is important that you have your vehicle
serviced at the proper times. These intervals
serve two purposes: first is to maintain the
reliability of your vehicle and the second is
to keep the cost of owning your vehicle
down.
It is your responsibility to have all scheduled
maintenance performed and to make sure
that the materials used meet the
specifications identified in this owner's
manual. See Capacities and Specifications
(page 400).
Failure to perform scheduled maintenance
and regularly inspect your vehicle may result
in vehicle damage not covered by the vehicle
Warranty.
Why Maintain Your Vehicle at Your
Dealership?
Our Genuine Replacement Parts
Dealerships stock our parts and our
authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed at
your dealership carry a nationwide 24-month
or unlimited mile (kilometer) parts and labor
limited warranty.
If you do not use our authorized parts they
may not meet our specifications and could
affect emissions compliance.
Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved reliability,
durability and resale value. To maintain the
proper performance of your vehicle and its
emission control systems, make sure you
have scheduled maintenance performed at
the designated intervals.
Your vehicle comes with the Intelligent
Oil-Life Monitor system, a message appears
in the information display at the proper oil
change interval. This interval may be up to
one year or
10,000 mi (16,000 km), hybrid
vehicles could exceed 10,000 mi (16,000 km).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or 500 mi (800 km)
of the message appearing. Make sure to
reset the Intelligent Oil-Life Monitor after
each oil change. See Resetting the Engine
Oil Change Reminder
(page 339).
