Do Not Operate The Engine With Failed Parts
All engine failures give some warning before the parts
fail. Be on the alert for changes in performance, sounds,
and visual evidence that the engine requires service.
Some important clues are:
•engine misfiring or vibrating severely
•sudden loss of power
•unusual engine noises
•fuel, oil or coolant leaks
•sudden change, outside the normal operating range, in
the engine operating temperature
•excessive smoke
•oil pressure drop
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms engine coolant and
permits quicker starts in cold weather. Connect the heater
cord to a ground-fault interrupter protected 110–115 Volt
AC electrical outlet with a grounded, three-wire exten-
sion cord.
Its use is recommended for environments that routinely
fall below -10°F (-23°C). It should be used when the
vehicle has not been running for long periods of time and
should be plugged in two hours prior to start. Its use is
required for cold starts with temperatures under -20°F
(-28°C).
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.

mark. The total capacity from the MIN mark to the MAX
mark is 1.3 qts (1.2 L).
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could damage
your engine.
NOTE:It is possible for your oil level to be slightly
higher than a previous check. This would be due to diesel
fuel that may temporarily be in the crankcase due to
operation of the diesel particulate filter regeneration
strategy. This fuel will evaporate out under normal
operation.
Never operate the engine with oil level below the “MIN”
mark or above the upper “MAX” mark.

Refer to the “Maintenance Schedule” for the proper
maintenance intervals.

CAUTION!
Your vehicle is equipped with an advanced technol-
ogy Diesel Engine and an emission device designed
to limit Diesel Particulate Emissions from being
released into the atmosphere. The durability of your
engine and life expectancy of this diesel particulate
filter emission device is highly dependent on the use
of the correct engine oil.

3. Open the water drain valve, and let any accumulated
water drain.
4. Close the water drain valve.
5. Remove bottom cover using a strap wrench. Rotate
counterclockwise for removal. Remove the used o-ring
and discard it.
6. Remove the used filter cartridge from the housing and
dispose of it according to your local regulations.
7. Wipe the sealing surfaces of the lid and housing clean.
8. Install a new o-ring into the ring groove on the filter
housing and lubricate with clean engine oil.
NOTE:WIF (Water In Fuel) sensor is re-usable. Service
kit comes with new o-ring for filter canister and WIF
sensor.Priming If The Engine Has Run Out Of Fuel
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
1. Add a substantial amount of fuel to the tank, approxi-
mately 2 to 5 gal (8L to 19L).
2. Press ignition switch twice without your foot on brake
to put vehicle in Run position. This will activate the in
tank fuel pump for approximately 30 seconds. Repeat
this process twice.
3. Start the engine using the “Normal Starting” proce-
dure. Refer to “Starting Procedures” in “Starting and
Operating” for further information.

MAINTENANCE SCHEDULE
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 ser-
vice 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 Operat-
ing 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 otherthan your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” in “Understanding Your
Instrument Panel” for further information.
NOTE:Under no circumstances should oil change inter-
vals 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
128 MAINTENANCE SCHEDULE

•Use the appropriate transmission gear to prevent
engine lugging.
•Observe vehicle oil pressure and temperature indica-
tors.
•Check the coolant and oil levels frequently.
•Vary throttle position at highway speeds when carry-
ing or towing significant weight.
NOTE:Light duty operation such as light trailer towing
or no load operation will extend the time before the
engine is at full efficiency. Reduced fuel economy and
power may be seen at this time.For additional vehicle break-in requirements, refer to
“Trailer Towing” in “Starting And Operating” of the
Owners Manual.
Because of the construction of the Cummins® turbo-
charged diesel engine, engine run-in is enhanced by
loaded operating conditions which allow the engine
parts to achieve final finish and fit during the first 6,000
miles (10 000 km).
150 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Maintaining Your
Vehicle.” Follow the warnings under the “Cooling
System Pressure Cap” paragraph.
6. Brake Warning Light
This light monitors various brake functions,
including brake fluid level and parking brake
application. If the brake light turns on it may
indicate that the parking brake is applied, that
the brake fluid level is low, or that there is a problem with
the Anti-lock Brake System reservoir.If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with the
Brake Booster has been detected by the Anti-Lock Brake
System (ABS)/Electronic Stability Control (ESC) system.
In this case, the light will remain on until the condition
has been corrected. If the problem is related to the brake
booster, the ABS pump will run when applying the brake
and a brake pedal pulsation may be felt during each stop.
The dual brake system provides a reserve braking capac-
ity in the event of a failure to a portion of the hydraulic
system. A leak in either half of the dual brake system is
indicated by the Brake Warning Light, which will turn on
when the brake fluid level in the master cylinder has
dropped below a specified level.
The light will remain on until the cause is corrected.

8. Seat Belt Reminder Light
When the ignition switch is first turned to
ON/RUN, this light will turn on for four to
eight seconds as a bulb check. During the bulb
check, if the driver’s seat belt is unbuckled, a
chime will sound. After the bulb check or when driving,
if the driver’s seat belt remains unbuckled, the seat belt
reminder light will flash or remain on continuously. Refer
to “Occupant Restraints” in “Things To Know Before
Starting Your Vehicle” for further information.
9. Air Bag Warning Light
This light will turn on for four to eight seconds
as a bulb check when the ignition switch is first
turned to ON/RUN. If the light is either not on
during starting, stays on, or turns on while
driving, have the system inspected at an authorizeddealer as soon as possible. Refer to “Occupant Restraints”
in “Things To Know Before Starting Your Vehicle” for
further information.
10. Engine Oil Pressure
The pointer should always indicate some oil pressure
when the engine is running. A continuous high or low
reading under normal driving conditions may indicate a
lubrication system malfunction. Immediate service
should be obtained from an authorized dealer.
If the gauge pointer moves to either extreme of the gauge,
the Check Gauges indicator will illuminate and a single
chime will sound.
11. Speedometer
The speedometer shows the vehicle speed in miles per
hour and/or kilometers per hour (mph/km/h).
