ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light.” It will
also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor Light” on could cause further damage to the
emission control system. It could also affect fuel
economy and driveability. The vehicle must be
serviced before any emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas

Frequency Of Oil Change
Road conditions and your style of driving affect the
interval at which your oil should be changed. Check the
following to determine if ANYapply to you:
•Day or night temperatures are below 32°F (0°C).
•Stop and Go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16.2 km).
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C).
•Trailer towing, Taxi, Police or delivery service (com-
mercial service).
•Off-Road or desert operation.
•If equipped for and operating with E-85 (ethanol)
fuel.
NOTE: IfANY of these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedules section of this manual.
If NONE of these apply to you, then change your engine
oil every 6,000 miles (10 000 km) or 6 months, whichever
comes first and follow schedule Aof the Maintenance
Schedules section of this manual.

Every 50 hours of use.
Dusty Conditions
Driving through dust-laden air increases the problems of
keeping abrasive materials out of the engine. Under these
conditions, special attention should be given to the
engine air cleaner. The crankcase ventilation system

To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.
Maintenance-Free Battery
All Dodge trucks are equipped with maintenance-free
batteries. You will never have to add water, nor is
periodic maintenance required.
WARNING!
Battery posts, terminals, and related accessories con-
tain lead and lead compounds. Always wash hands
after handling the battery.
To determine the battery charge, check the battery test
indicator (if equipped) on top of the battery. Refer to the
illustration.
