Heavy Duty Use Of The Vehicle
Change engine oil at 4,000 miles (6,500 km) or
350 hours of engine run time if the vehicle is
operated in a dusty and off road environment or
is operated predominately at idle or only very
low engine RPM. This type of vehicle use is
considered Severe Duty.
6.2L SUPERCHARGED AND 6.4L
E
NGINES
The scheduled maintenance services listed in
this manual must be done at the times or
mileages specified to protect your vehicle
warranty and ensure the best vehicle
performance and reliability. More frequent
maintenance may be needed for vehicles in
severe operating conditions, such as dusty
areas and very short trip driving. Inspection and
service should also be done anytime a
malfunction is suspected.
The oil change indicator system will remind you
that it is time to take your vehicle in for
scheduled maintenance.
An “Oil Change Required” message will be
displayed in the instrument cluster and a single
chime will sound, indicating that an oil change
is necessary. Based on engine operation conditions, the oil
change indicator message will illuminate. This
means that service is required for your vehicle.
Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
NOTE:
The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicle's oil if it has been six
months since your last oil change, even if the
oil change indicator message is NOT illumi-
nated.
Change your engine oil more often if you drive
your vehicle off-road/track usage for an
extended period of time.
Under no circumstances should oil change
intervals exceed 6,000 miles (10,000 km) or
6 months, whichever comes first.
WARNING!
You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge and
the right equipment. If you have any doubt
about your ability to perform a service job,
take your vehicle to a competent mechanic.

Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.

(Continued)
Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type ther-
mostat. Other designs may result in unsatis -
factory engine coolant (antifreeze)
performance, poor gas mileage, and
increased emissions.
BRAKE SYSTEM
In order to ensure brake system performance,
all brake system components should be
inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder
when performing underhood services.
Clean the top of the master cylinder area before
removing the cap. Add fluid to bring the level up
to the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because
it may cause leaking in the system.
Add enough fluid to bring the level up to the
requirements described on the brake fluid
reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear.
However, low fluid level may be caused by a
leak and a checkup may be needed.
Use only brake fluid that has been
recommended by the manufacturer, and has
been kept in a tightly closed container to avoid
contamination from foreign matter or moisture.
Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your foot
resting or riding on the brake pedal can result
in abnormally high brake temperatures,
excessive lining wear, and possible brake
damage. You would not have your full braking
capacity in an emergency.
WARNING!

Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri -
cants” in “Technical Specifications” for
further information. Using the wrong type
of brake fluid can severely damage your
brake system and/or impair its perfor -
mance. The proper type of brake fluid for
your vehicle is also identified on the orig -
inal factory installed hydraulic master
cylinder reservoir.
To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master
cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake failure.
This could result in a collision.

SUGGESTIONS FOR OBTAINING SERVICE
FOR YOUR VEHICLE
PREPARE FOR THE APPOINTMENT
If you are having warranty work done, be sure to
have the right papers with you. Take your
warranty folder. All work to be performed may
not be covered by the warranty. Discuss
additional charges with the service manager.
Keep a maintenance log of your vehicle's
service history. This can often provide a clue to
the current problem.
PREPARE A LIST
Make a written list of your vehicle's problems or
the specific work you want done. If you've had
an accident or work done that is not on your
maintenance log, let the service advisor know.
BE REASONABLE WITH REQUESTS
If you list a number of items and you must have
your vehicle by the end of the day, discuss the
situation with the service advisor and list the
items in order of priority. At many authorized dealers, you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is
advisable to make these arrangements when
you call for an appointment.
IF YOU NEED ASSISTANCE
The manufacturer and its authorized dealers
are vitally interested in your satisfaction. We
want you to be happy with our products and
services.
Warranty service must be done by an
authorized dealer. We strongly recommend that
you take the vehicle to an authorized dealer.
They know your vehicle the best, and are most
concerned that you get prompt and high quality
service. The manufacturer's authorized dealers
have the facilities, factory-trained technicians,
special tools, and the latest information to
ensure the vehicle is fixed correctly and in a
timely manner.
This is why you should always talk to an
authorized dealer service manager first. Most
matters can be resolved with this process.
If for some reason you are still not satisfied,
talk to the general manager or owner of the
authorized dealer. They want to know if you
need assistance.
If an authorized dealer is unable to resolve
the concern, you may contact the manufac
-
turer's customer center.
Any communication to the manufacturer's
customer center should include the following
information:
Owner's name and address
Owner's telephone number (home, mobile,
and office)
Authorized dealer name
Vehicle Identification Number (VIN)
Vehicle delivery date and mileage
