Biodiesel
WARNING: Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You can operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
• Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less.
• Only use biodiesel fuel of good quality
that complies with industry standards.
• Follow the recommended service
maintenance intervals. See
General
Maintenance Information (page 664).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month.
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequently appearing LOW FUEL
PRESSURE message. Use of biodiesel in concentrations greater
than 20% can cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that could
result in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
We recommend SAE 5W-40 oil for fuels
with greater than 5% biodiesel (B5). For
more information about oil change
intervals and other maintenance when
operating on biodiesel.
See Special
Operating Conditions Scheduled
Maintenance
(page 675).
Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in diesel fuel. Ask the service station
attendant to confirm the biodiesel content
of diesel fuel, if you do not see a label on
the fuel pump.
If you plan to park or store your vehicle for
more than 1 month, then you should empty
your vehicle fuel tank of biodiesel fuel. You
should fill the tank with a pure
petroleum-based diesel fuel and run your
vehicle for a minimum of 30 minutes.
Note: Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use diesel fuel with lower biodiesel
content, try another brand or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high-quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.

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 574).
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 511).
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.
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.
