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 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 Condi-
tions 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 thanyour authorized dealer, the message can be reset by
referring to the steps described under “Instrument Cluster
Display” 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, and power steering, and fill as needed
• Check function of all interior and exterior lights

• Completely fill the Diesel Exhaust Fluid tank.
• Drain water from fuel filter assembly.
• 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.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Inspect brake pads, shoes, rotors, drums, hoses and

Vehicle Security Alarm System (if equipped). Then, prior to
the end of the 15-minute cycle, place the ignition to the
ON/RUN position.
NOTE:The ignition switch must be in the ON/RUN
position in order to drive the vehicle.
Remote Start Comfort Systems — If Equipped
When remote start is activated, the heated steering wheel,
and driver heated seat features will automatically turn on
in cold weather. In warm weather, the driver vented seat
feature will automatically turn on when the remote start is
activated. These features will stay on through the duration
of remote start or until the ignition switch is turned to the
ON/RUN position.
The Remote Start Comfort System can be activated and
deactivated through the Instrument Cluster Display. For
more information on Remote Start Comfort System opera-
tion refer to your Owners Manual.
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins turbocharged diesel engine does not require
a break-in period due to its construction. Normal operation
is allowed, providing the following recommendations are
followed: •
Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine
lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying
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 Own-
ers Manual.
Because of the construction of the Cummins turbocharged
diesel engine, engine run-in is enhanced by loaded oper-
ating conditions which allow the engine parts to achieve
final finish and fit during the first 6,000 miles (10 000 km).
94 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE
3. Speedometer•Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel filler door is located.
5. DEF Gauge •The DEF Gauge displays the actual level of Diesel
Exhaust Fluid in the DEF tank. Diesel Exhaust Fluid
(DEF) is required to maintain normal vehicle operation
and emissions compliance. If something is wrong with
the gauge, a DEF Warning Message or Malfunction
Indicator Light (MIL) will be displayed. More infor-
mation is available in the Instrument Cluster Display
section under the heading of Diesel Exhaust Fluid
(DEF) Warning Messages.
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 Ve-
hicle.” Follow the warnings under the “Cooling Sys-
tem Pressure Cap” paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF) to
the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Engine Coolant Temperature •This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures
when driving in hot weather, up mountain grades, or
in heavy stop and go traffic. If the red Warning Light
turns on while driving, safely bring the vehicle to a
stop, and turn off the engine. DO NOT operate the
vehicle until the cause is corrected.

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.
