•Electric Power Steering Malfunction Warning Light
This telltale is on when the Electric Power
Steering is not operating and needs service.
• Trailer Brake Disconnected Warning Light
This telltale is on when the Trailer Brake has
been disconnected.
7. Audio/Phone Information And Sub-menu Information
Whenever there are sub-menus available, the position
within the sub-menu is shown here.
The main display area will normally display the main
menu or the screens of a selected feature of the main
menu. The main display area also displays “pop up”
messages that consist of approximately 60 possible warn-
ing or information messages. These pop up messages fall
into several categories: •
Five Second Stored Messages
When the appropriate conditions occur, this type of
message takes control of the main display area for five
seconds and then returns to the previous screen. Most of
the messages of this type are then stored (as long as the
condition that activated it remains active) and can be
reviewed from the “Messages” main menu item. As long
as there is a stored message, an “i” will be displayed in
the EVIC’s compass/outside temp line. Examples of this
message type are “Right Front Turn Signal Lamp Out”
and “Low Tire Pressure”.
• Unstored Messages
This message type is displayed indefinitely or until the
condition that activated the message is cleared. Examples
of this message type are “Turn Signal On” (if a turn signal
is left on) and “Lights On” (if driver leaves the vehicle).

MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
maintenance schedule, there are other components which
may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or per-
form repairs and service when necessary could
result in more costly repairs, damage to other
components or negatively impact vehicle perfor-
mance. Immediately have potential malfunctions
examined by an authorized dealership or qualified
repair center.
(Continued)
CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.

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)” or “Driver Information Dis-
play (DID)” 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

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 position.
The Remote Start Comfort System can be activated and
deactivated through the EVIC/DID. For more informa-
tion on Remote Start Comfort System operation refer to
your Owners Manual.
ENGINE BREAK-IN RECOMMENDATIONS
The Cummins turbocharged diesel engine does not re-
quire a break-in period due to its construction. Normal
operation is allowed, providing the following recommen-
dations 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 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 141
Page 224 of 338

Key Ignition Park Interlock
This vehicle is equipped with a Key Ignition Park Inter-
lock which requires the transmission to be in PARK
before the ignition switch can be turned to the LOCK/
OFF (key removal) position. The key fob can only be
removed from the ignition when the ignition is in the
LOCK/OFF position, and the transmission is locked in
PARK whenever the ignition switch is in the LOCK/OFF
position.
Brake/Transmission Shift Interlock System
This vehicle is equipped with a Brake Transmission Shift
Interlock System (BTSI) that holds the shift lever in PARK
unless the brakes are applied. To shift the transmission
out of PARK, the ignition switch must be turned to the
ON/RUN position (engine running or not) and the brake
pedal must be pressed.
Six-Speed Automatic Transmission — If Equipped
Chassis Cab models (with automatic transmission) use
the AS69RC transmission (which is equipped with a
Power Take-Off [PTO] access cover on the side of the
transmission case). Pickup models may use either the
AS69RC transmission, or the 68RFE transmission (which
has no PTO access cover).
The transmission gear position display (located in the
instrument cluster) indicates the transmission gear range.
The shift lever is mounted on the right side of the steering
column. You must press the brake pedal to move the shift
lever out of PARK (refer to “Brake/Transmission Shift
Interlock System” in this section). To drive, move the shift
lever from PARK or NEUTRAL to the DRIVE position.
Pull the shift lever toward you when shifting into RE-
VERSE or PARK, or when shifting out of PARK.
The electronically-controlled transmission provides a
precise shift schedule. The transmission electronics are
