• 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
Owner ’s 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).

To use the “Slide-On-Rod” feature, rotate the sun visor
downward and unclip it. Pull the sun visor along the
“Slide-On-Rod” until the sun visor is in the desired
position. Trailer Towing Mirrors — If Equipped
These mirrors are designed with an adjustable mirror
head to provide a greater vision range when towing
extra-wide loads. To change position inboard or out-
board, the mirror head should be rotated (flipped in or
out).

NOTE: Fold the trailer towing mirrors rearward prior to
entering an automated car wash.
A small blindspot mirror is located next to main mirror
and can be adjusted separately. SEATS
Seats are a part of the Occupant Restraint System of the
vehicle.
WARNING!• It is dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured
or killed.
• Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts. In a collision, people riding in these areas are
more likely to be seriously injured or killed.
• Be sure everyone in your vehicle is in a seat and
using a seat belt properly.Blindspot Mirror142 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING! (Continued)• Before using ParkSense, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the
vehicle is not used for towing. Failure to do so can
result in injury or damage to vehicles or obstacles
because the hitch ball will be much closer to the
obstacle than the rear fascia when the loudspeaker
sounds the continuous tone. Also, the sensors
could detect the ball mount and hitch ball assem-
bly, depending on its size and shape, giving a false
indication that an obstacle is behind the vehicle.
PARKSENSE FRONT AND REAR PARK ASSIST —
IF EQUIPPED
The ParkSense Park Assist system provides visual and
audible indications of the distance between the rear
and/or front fascia and a detected obstacle when backing up or moving forward, e.g. during a parking maneuver.
Refer to ParkSense System Usage Precautions for limita-
tions of this system and recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled at one of
these gear selector positions, the system will remain
active until the vehicle speed is increased to approxi-
mately 7 mph (11 km/h) or above. A display warning
will appear in the Electronic Vehicle Information Center
(EVIC) or Driver Information Display (DID) indicating
the vehicle is above ParkSense operating speed. The
system will become active again if the vehicle speed is
decreased to speeds less than approximately 6 mph
(9 km/h).196 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

or open position. A lowered tailgate could provide a
false indication that an obstacle is behind the vehicle.
CAUTION!• ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below
the sensors will not be detected when they are in
close proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when
an obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense. WARNING!• Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be sure
to check for pedestrians, animals, other vehicles,
obstructions, and blind spots before backing up.
You are responsible for safety and must continue to
pay attention to your surroundings. Failure to do so
can result in serious injury or death.
• Before using ParkSense, it is strongly recom-
mended that the ball mount and hitch ball assem-
bly is disconnected from the vehicle when the

Electronic Throttle Control (ETC) Warning Light
Red Telltale
Light What It Means
Electronic Throttle Control (ETC) Warning Light
This light informs you of a problem with the Electronic Throttle Control (ETC) system. If a
problem is detected while the engine is running, the light will either stay on or flash de-
pending on the nature of the problem. Cycle the ignition key when the vehicle is safely and
completely stopped and the transmission is placed in the PARK position. The light should
turn off. If the light remains on with the engine running, your vehicle will usually be driv-
able; however, see an authorized dealer for service as soon as possible.
If the light continues to flash when the engine is running, immediate service is required and
you may experience reduced performance, an elevated/rough idle, or engine stall and your
vehicle may require towing. The light will come on when the ignition is first turned to ON/
RUN and remain on briefly as a bulb check. If the light does not come on during starting,
have the system checked by an authorized dealer. 4UNDERSTANDING YOUR INSTRUMENT PANEL 247

Yellow Telltale
Light What It Means
Engine Check/Malfunction Indicator Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine and automatic transmission control systems. The
light will illuminate when the ignition is in the ON position before engine start. If the bulb
does not come on when turning the key from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap, poor quality fuel, etc., may illuminate
the light after engine start. The vehicle should be serviced if the light stays on through sev-
eral typical driving styles. In most situations, the vehicle will drive normally and will not
require towing.250 UNDERSTANDING YOUR INSTRUMENT PANEL
