Hill descent mode
Hill descent allows the driver to set and maintain vehicle speed while
descending steep grades regardless of surface conditions. Refer to
Message centerin theInstrument Clusterchapter of yourOwner’s
Guidefor hill-descent related messages.
Hill descent control can maintain vehicle speeds on downhill grades
between 2 and 20 mph (3 and 32 km/h). Between 20 and 40 mph (32
and 64 km/h), the system remains enabled, but descent speed cannot be
set or maintained. If vehicle speed is above 40 mph (64 km/h), the
system is disabled. After this point, vehicle speed must drop below
40 mph (64 km/h), and the hill descent control button must be pressed
again to engage the feature.
WARNING:Hill descent mode does not provide hill hold at zero
mph (0 km/h). When stopped, the parking brake must be applied
and/or the vehicle must be placed in P (Park) or it may roll away.
Hill descent control requires a cooling down interval after a period of
sustained use. The amount of time that the feature can remain active
before cooling varies with conditions. The system will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.
Enabling hill descent control and setting the descent speed
1. Press and release the hill descent
button located on the floor console.
A light on the button will illuminate
and a one second chime will sound
when this feature is activated.
2. To increase descent speed, press the accelerator pedal until the
desired speed is reached.
3. To decrease descent speed, press the brake pedal until the desired
speed is reached.
Whether accelerating or decelerating, once the desired descent speed is
reached, remove your feet from the pedals and the chosen vehicle speed
will be maintained.

Upfitter controls
The auxiliary switch board on the
center console makes aftermarket
customization easier, with four
prewired switches attached to the
power distribution box for electrical
accessories.
These switches are labeled AUX 1,
AUX 2, AUX 3 and AUX 4. They will
only operate while the ignition is in the on position, whether the engine
is running or not. It is, however, recommended that the engine remain
running to maintain battery charge when using the switches for extended
duration or higher current draws. When switched on by the operator
they provide 10 amps, 15 amps or 30 amps of electrical battery power
for a variety of uses.
The switches control relays and fuses that are located under the hood in
the auxiliary power distribution box. Refer to theRoadside Emergencies
chapter of your Owner’s Guide for information on fuse and relay
locations. See your authorized dealer for service.
There will also be one power lead for each switch found as a blunt-cut
and sealed wire located to the right of the glove box door and just above
the passenger side kick panel.
Additional pass through circuits that run through the dash panel to
under the hood are located in the same location.
The relays are coded as follows:
Switch Circuit number Wire color Fuse
AUX 1 CAC05 Yellow 30A
AUX 2 CAC06 Green with
Brown Trace30A
AUX 3 CAC07 Violet with
Green Trace15A
AUX 4 CAC08 Brown 10 A
FRONT OFF-ROAD CAMERA SYSTEM (IF EQUIPPED)
The front view camera is designed to be used as an aid in off-road
conditions, such as rock-climbing, slow-speed maneuvering, and cresting
hills when the front view may otherwise be obstructed through the
windshield. This feature adds front imaging off-road assistance to the
driver at vehicle speeds less than 15 mph (25 km/h).
