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
Maintenance Plan — Diesel Fuel
Up To B5 Biodiesel
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.

WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stop-
ping distance. Use tires of the recom-
mended load capacity for your vehicle.
Never overload them.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to
the safe and satisfactory operation of your
vehicle. Four primary areas are affected by
improper tire pressure:
• Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride ComfortSafety
WARNING!
• Improperly inflated tires are dangerous
and can cause collisions.
• Underinflation increases tire flexing and
can result in overheating and tire failure.
• Overinflation reduces a tire's ability to cushion shock. Objects on the road and
chuckholes can cause damage that re-
sult in tire failure.
• Overinflated or underinflated tires can
affect vehicle handling and can fail sud-
denly, resulting in loss of vehicle con-
trol.
• Unequal tire pressures can cause steer-
ing problems. You could lose control of
your vehicle.
• Unequal tire pressures from one side of
the vehicle to the other can cause the
vehicle to drift to the right or left.
• Always drive with each tire inflated to
the recommended cold tire inflation
pressure. Both under-inflation and over-inflation affect
the stability of the vehicle and can produce a
feeling of sluggish response or over respon-
siveness in the steering.
NOTE:
• Unequal tire pressures from side to side
may cause erratic and unpredictable steer-
ing response.
• Unequal tire pressure from side to side may cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consump-
tion.
Tread Wear
Improper cold tire inflation pressures can
cause abnormal wear patterns and reduced
tread life, resulting in the need for earlier tire
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort-
able ride. Over-inflation produces a jarring
and uncomfortable ride.
