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 environ-
ment or is operated predominately at idle or
only very low engine RPM’s. This type of
vehicle use is considered Severe Duty.
SCHEDULED MAINTENANCE — DIESEL
ENGINE
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for scheduled
maintenance.
Based on engine operation conditions, the oil
change indicator message will illuminate in
the instrument cluster. This means that ser-
vice is required for your vehicle. Operating
conditions such as frequent short-trips,
trailer tow, and extremely hot or cold ambient
temperatures will influence when the “Oil
Change Required” message is displayed. Se-
vere Operating Conditions can cause the
change oil message to illuminate as early as3,500 miles (5,600 km) since last reset.
Have your vehicle serviced as soon as pos-
sible, within the next 500 miles (805 km).
NOTE:
Under no circumstances should oil change
intervals exceed 18,500 miles (29,773 km)
or twelve months, whichever comes first.
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check the tire inflation pressures and look
for unusual wear or damage
• Check the fluid levels of the coolant reser- voir, brake master cylinder, and power
steering, and fill as needed
• Check function of all interior and exterior lights

Required Maintenance Intervals.
Refer to the maintenance schedules on the
following page for the required maintenance
intervals.
At Every Oil Change Interval As Indicated By The Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of
irregular wear, even if it occurs before your
next scheduled service.
• Inspect battery and clean and tighten ter- minals as required.
• Inspect brake pads, rotors, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or off-road conditions.

Additional Maintenance — B6 To B20 Biodiesel
NOTE:
• Under no circumstances should oil changeintervals exceed 10,000 miles (16 093km)
or six months, whichever comes first. • The owner is required to monitor mileage
for B6-B20 biodiesel, the automatic oil
change indicator system does not reflect
the use of biofuels.

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 com-
petent mechanic.
WARNING!
•Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an ac-
cident.

Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
• Driving style.
• Tire pressure - Improper cold tire inflationpressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death. Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
See the Tire Sizing Chart example found in
the “Tire Safety Information” section of this
manual for more information relating to the
Load Index and Speed Symbol of a tire.
