Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by referring to the steps described
under “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
Instrument Panel” in your Owner’s Manual on the DVD for further information.
NOTE:
•1500 Models Only
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km)
or twelve months on 1500 trucks, whichever comes first.
•2500 – 3500 Models
Under no circumstances should oil change intervals exceed 8,000 miles (13,000 km)
or twelve months on 2500 – 3500 trucks, whichever comes first.
•Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle is operated in a dusty and
off road environment. This type of vehicle use is considered Severe Duty
Once A Month Or Before A Long Trip:
• Check engine oil level
• Check windshield washer fluid level
• Check tire pressure and look for unusual wear or damage. Rotate tires at the first sign of irregular wear, even if it occurs before the oil indicator system turns on.
•
Check the fluid levels of the coolant reservoir, brake master cylinder, power steering
(2500/3500 Models Only) and automatic transmission (six-speed only) as needed
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, 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.
• Lube the front drive shaft fitting (2500/3500 (4x4) models only).

MAINTENANCE SCHEDULE — 1500 3.0L 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. This means that service is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or cold ambient temperatures
will influence when the “Oil Change Required” message is displayed. Severe
Operating Conditions can cause the change oil message to illuminate as early as
3,500 miles (5,600 km) since last reset. Have your vehicle serviced as soon as
possible, within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator message after completing
the scheduled oil change. If a scheduled oil change is performed by someone other than
your authorized dealer, the message can be reset by referring to the steps described
under “Instrument Cluster Warning Lights” in “What To Do In Emergencies” in this
guide or “Electronic Vehicle Information Center (EVIC)” in “Understanding Your
Instrument Panel” in your Owner’s Manual on the DVD for further information.
NOTE:
Under no circumstances should oil change intervals exceed 10,000 miles (16,000 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 reservoir, brake master cylinder, power steering
and transmission as needed
• Check function of all interior and exterior lights
Required Maintenance
Refer to the Maintenance Schedules on the following pages for required maintenance.
At Every Oil Change Interval As Indicated By Oil Change Indicator System:
• Change oil and filter.
• Completely fill the Diesel Exhaust Fluid tank.
• Rotate the tires. Rotate at the first sign of irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten terminals as required.
• Inspect automatic transmission fluid if equipped with dipstick.
• Inspect brake pads, shoes, rotors, drums, hoses and park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
