CHECKING THE COOLANT
When the engine is cold, check the
concentration and level of the coolant at
the intervals listed in the scheduled
maintenance information. See Scheduled
Maintenance (page 482).
Note:Make sure that the coolant level is
between the minimum and maximum marks
on the coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -29°F (-34°C) and -35°F
(-37°C). Coolant concentration should be
checked using a refractometer. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentration.

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, ventilatedplace.
• 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 tostorage 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 toremove 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 greaterthan 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. Keepconnections 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.
355
Storing Your Vehicle

Note:If you intend on parking your vehicle
for an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so to
reduce the risk of increased corrosion of the
brake discs, brake pads and linings.
Tires
• Maintain recommended air pressure.
Note: If you intend on parking your vehicle
for an extended period after cleaning the
wheels with a wheel cleaner, drive your
vehicle for a few minutes before doing so.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
REMOVING YOUR VEHICLE
FROM STORAGE
When your vehicle is ready to come out of
storage, do the following:
• We recommend that you change the engine oil before you use your vehicle
again.
• Wash your vehicle to remove any dirt or grease film build-up on window
surfaces.
• Check windshield wipers for any deterioration.
• Check under the hood for any foreign material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign material that may have collected
during storage.
• Check tire pressures and set tire inflation per the Tire Label.
• Check brake pedal operation. Drive your vehicle 15 ft (4.5 m) back and
forth to remove rust build-up. • Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the battery cable ends and check for
damage.
Contact an authorized dealer if you have
any concerns or issues.

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.
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.
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or 5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or 10,000 mi (16,000 km) between oil
change intervals.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption including extended time at
high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. Check the engine
oil level at every refueling and adjust to
maintain proper levels to avoid engine
damage.
It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.

Scheduled Maintenance

We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. Have discolored fluids that also
show signs of overheating or foreign
material contamination checked
immediately.Make sure to change the vehicle’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections.
Check Every Month
The air filter restriction gauge.1

Scheduled Maintenance

Be sure to ask your dealership service
advisor or technician about the multi-point
vehicle inspection. It is a comprehensive
way to perform a thorough inspection of
your vehicle. Your checklist gives you
immediate feedback on the overall
condition of your vehicle.
NORMAL SCHEDULED
MAINTENANCE
Intelligent Oil-Life Monitor™
Your vehicle has an Intelligent Oil-Life
Monitor that determines when you should
change the engine oil based on how you
use your vehicle. By using several
important factors in its calculations, the
monitor helps reduce the cost of owning
your vehicle and reduces environmental
waste at the same time.This means you do not have to remember
to change the oil on a mileage-based
schedule. Your vehicle lets you know when
an oil change is due by displaying a
message in the information display.
The following table provides examples of
vehicle use and its impact on oil change
intervals. It is a guideline only. Actual oil
change intervals depend on several factors
and generally decrease with severity of
use.
When to Expect the OIL CHANGE REQUIRED Message
