Adding accessories can affect the vehicle
performance. SeeAccessories and
Modifications 0253.
Hill Descent Control (HDC)
If equipped, HDC can be used when driving
downhill. It sets and maintains vehicle speed
while descending a very steep incline in a
forward or reverse gear.
To activate HDC, in the controls app on the
infotainment home screen, select Controls >
Drive & Park > Hill Descent Control.
Press ON or OFF to enable or disable HDC.
Vehicle speed must be below 60 km/h
(37 mph).
The HDC light displays on the instrument
cluster when enabled.
HDC can maintain vehicle speeds between
4 and 30 km/h (3 and 19 mph) on an incline
greater than or equal to a 10% grade. A blinking HDC light indicates that the
system is actively applying the brakes to
maintain vehicle speed.
Set speed is established as soon as you
enable HDC. Apply the accelerator to
increase, or the brake pedal to decrease, the
set speed.
Smaller HDC speed control adjustments are
accomplished using the cruise up or down
buttons. Each tap of the +RES will increase
the set speed by 0.8 km/h (0.5 mph), while
each tap of the SET–
will decrease the set
speed by 0.8 km/h (0.5 mph). This adjusted
speed becomes the new set speed.
HDC will remain enabled between 30 and
60 km/h (19 and 37 mph); however, vehicle
speed cannot be set or maintained in this
range. It will automatically disable if the
vehicle speed is above 80 km/h (50 mph) or
above 60 km/h (37 mph) for at least
30 seconds.
5must be pressed again to
re-enable HDC.
When enabled, if the vehicle is at a speed
above 30 km/h (19 mph) and less than
60 km/h (37 mph), a Driver Information
Center (DIC) message will display instructing
the driver to reduce speed for HDC
operation. Cruise control will not function while HDC is
enabled and vehicle speed is below 40 km/h
(25 mph).
Driver Mode Control
Driver Mode Control (DMC) allows you to
adjust the overall driving experience by
selecting different driving modes.
If equipped, driver mode control may have
the following modes: Normal, Off-Road,
Tow/Haul, Terrain, and Baja. Drive mode
availability and affected vehicle subsystems
are dependent upon vehicle trim level,
region, and optional features.
All modes, other than the default (Normal),
display a unique and persistent indicator on
the instrument cluster when selected.
When entering a mode, there is an
information icon on the infotainment screen.
Select the information icon to get more
information and helpful hints on the
selected mode.

188 Driving and Operating
Mode Activation
To activate each mode, turn the MODE knob
on the center console in either direction.
Mode Descriptions
Normal Mode :Use this mode for normal
city and highway driving. This setting
provides balance between comfort and
handling. This is the setting the vehicle will
default to every time it is started, unless
Tow/Haul mode has been activated within
the last four hours. See “Tow/Haul Mode”
later in this section.
7Off-Road Mode : Use this mode only
for off-road recreational driving. Off-Road
Mode should be used to improve driving at
moderate speeds on grass, gravel, dirt,
unpaved roads, or deep snow. If equipped,
this mode modifies steering, pedal map,
transmission shift points, Four-Wheel Drive
AUTO, Antilock Brake System (ABS),
Electronic Stability Control (ESC), and
Traction Control System (TCS) performance.
Off-Road mode optimizes ABS performance
to decrease stopping distances for
deformable or loose surfaces.
For more information on off-road driving,
see Off-Road Driving 0153.
gTerrain Mode : Use this mode when
traveling on challenging road conditions at
lower speeds, such as a two-track, difficult
terrain, or rock crawling. This mode allows
for one pedal driving which automatically
applies the vehicle brakes when the
accelerator pedal position is decreased. This
can also be used for pulling a boat out of
the water on a trailer. Terrain mode functions when the vehicle is
in 4
mor 4n, and in D (Drive), R (Reverse),
or L (Low). When the vehicle is in L (Low),
the lower the gear, the more aggressive the
braking.
The following are the braking calibrations
for each gear:
.L1: Most aggressive
.L2 or D (Drive): Moderately aggressive
.L3–L8: Least aggressive
The vehicle uses more aggressive braking
calibrations for the above drive states when
it is in 4
ncompared to 4m.
When in Terrain Mode, the vehicle shifts
automatically, but holds a lower gear longer
to maximize engine torque. This is done so
vehicle momentum is not lost when driving
up a hill. This mode modifies steering, pedal
map, transmission shift points, ABS, ESC, and
TCS performance for better control at lower
speeds and over rough terrain.

that ABS is off, which may result in the
wheels locking during deceleration. See
Driver Mode Control0187.
If HDC was enabled prior to axle lock, it will
be automatically enabled when the locking
front axle is disengaged.
After pressing the switch to unlock the axle,
it may remain locked due to torque in the
driveline. The axle is more easily unlocked
by turning the steering wheel to the right
and to the left while traveling at a low
speed.
Cruise Control
With cruise control a speed of about
40 km/h (25 mph) or more can be
maintained without keeping your foot on
the accelerator. Cruise control does not work
at speeds below about 40 km/h (25 mph).
{Warning
Cruise control can be dangerous where
you cannot drive safely at a steady
speed. Do not use cruise control on
winding roads or in heavy traffic. (Continued)
Warning (Continued)
Cruise control can be dangerous on
slippery roads. On such roads, fast
changes in tire traction can cause
excessive wheel slip, and you could lose
control. Do not use cruise control on
slippery roads.
If the cruise control is being used and the
Traction Control (TCS) system or StabiliTrak/
Electronic Stability Control (ESC) begins to
limit wheel spin, the cruise control will
automatically disengage. See Traction
Control/Electronic Stability Control 0185. If a
collision alert occurs when cruise control is
activated, cruise control is disengaged. See
Forward Collision Alert (FCA) System 0215.
When road conditions allow you to safely
use it again, cruise control can be turned
back on.
If equipped with Hill Descent Control (HDC),
cruise control will disengage if HDC is Active.
If the brakes are applied, the cruise control
disengages.
5: Press to turn the system on or off.
A white indicator comes on in the
instrument cluster when cruise control is
turned on.
+RES : If there is a set speed in memory,
press briefly to resume to that speed or
press and hold to accelerate. If cruise control
is already active, use to increase vehicle
speed.
−SET : Press briefly to set the speed and
activate cruise control. If cruise control is
already active, use to decrease vehicle
speed.

Control
Use the accelerator pedal to increase the
vehicle speed. When you take your foot off
the pedal, the vehicle will slow down to the
previous set cruise speed. While pressing the
accelerator pedal or shortly following the
release to override cruise control, briefly
pressing
–SET will result in cruise control set
to the current vehicle speed.
Using Cruise Control on Hills
How well the cruise control will work on
hills depends on the vehicle speed, load, and
the steepness of the hills. When going up
steep hills, you might have to step on the
accelerator pedal to maintain your speed.
When going downhill, you might have to
brake or shift to a lower gear to keep your
speed down. If the brake pedal is applied,
cruise control will disengage.

196 Driving and Operating
Erasing Speed Memory
The cruise control set speed is erased from
memory if
5is pressed or if the ignition is
turned off.
Adaptive Cruise Control (Camera)
If equipped, Adaptive Cruise Control (ACC)
allows the cruise control set speed and
following gap to be selected. Read this
entire section before using this system. The
following gap is the following time between
your vehicle and a vehicle detected directly
ahead in your path, moving in the same
direction. If no vehicle is detected in your
path, ACC works like regular cruise control.
ACC uses a windshield mounted front
camera sensor.
If a vehicle is detected in your path, ACC can
apply acceleration or limited, moderate
braking to maintain the selected following
gap. To disengage ACC, apply the brake.
If ACC is controlling the vehicle speed when
the Traction Control System (TCS) or
StabiliTrak/Electronic Stability Control (ESC)
system activates, ACC may automatically
disengage. See Traction Control/Electronic
Stability Control 0185. When road
conditions allow ACC to be safely used, ACC can be turned back on. Disabling the TCS or
StabiliTrak/ESC system will disengage and
prevent engagement of ACC.
ACC can reduce the need for you to
frequently brake and accelerate, especially
when used on expressways, freeways, and
interstate highways. When used on other
roads, you may need to take over the
control of braking or acceleration more
often.
{Warning
ACC has limited braking ability and may
not have time to slow the vehicle down
enough to avoid a collision with another
vehicle you are following. This can occur
when vehicles suddenly slow or stop
ahead, or enter your lane. Also see
“Alerting the Driver”
later in this section.
Complete attention is always required
while driving and you should be ready to
take action and apply the brakes. See
Defensive Driving 0151.
{Warning
ACC will not detect or brake for children,
pedestrians, animals, or other objects.
Do not use ACC when:
.On winding and hilly roads or when
the sensors are blocked by snow, ice,
or dirt. The system may not detect a
vehicle ahead. Keep the entire front of
the vehicle clean.
.Visibility is poor due to rain, snow,
fog, dirt, insect residue, or dust; when
other foreign objects obscure the
camera and/or radar; or when the
vehicle in front or oncoming traffic
causes additional environmental
obstructions, such as road spray. ACC
performance is limited under these
conditions.
.On slippery roads where fast changes
in tire traction can cause excessive
wheel slip.
.With extremely heavy cargo loaded in
the cargo area or rear seat, or when
the vehicle is loaded in excess of load
limits. See Vehicle Load Limits 0162.

202 Driving and Operating
Passing a Vehicle While Using ACC
If the set speed is high enough, and the left
turn signal is used to pass a vehicle ahead
in the selected following gap, ACC may
assist by gradually accelerating the vehicle
prior to the lane change.
{Warning
When using ACC to pass a vehicle or
perform a lane change, the following
distance to the vehicle being passed may
be reduced. ACC may not apply sufficient
acceleration or braking when passing a
vehicle or performing a lane change.
Always be ready to manually accelerate
or brake to complete the pass or lane
change.
Stationary or Very Slow-Moving Objects
{Warning
ACC may not detect and react to stopped
or slow-moving vehicles ahead of you. For
example, the system may not brake for a
vehicle it has never detected moving. This
can occur in stop-and-go traffic or when a
vehicle suddenly appears due to a vehicle (Continued)
Warning (Continued)
ahead changing lanes. Your vehicle may
not stop and could cause a crash. Use
caution when using ACC. Your complete
attention is always required while driving
and you should be ready to take action
and apply the brakes.
Irregular Objects Affecting ACC
ACC may have difficulty detecting the
following objects:
.Vehicles in front of your vehicle that have
a rear aspect that is low, small,
or irregular
.An empty truck or trailer that has no
cargo in the cargo bed
.Vehicles with cargo extending from the
back end
.Non-standard shaped vehicles, such as
vehicle transport, vehicles with a side car
fitted, or horse carriages
.Vehicles that are low to the road surface
.Objects that are close to the front of your
vehicle
.Vehicles on which extremely heavy cargo
is loaded in the cargo area or rear seat
ACC Automatically Disengages
ACC may automatically disengage and the

P (Park) can be dangerous. Do not leave
the vehicle while it is being held at a
stop by ACC. Always place the vehicle in
P (Park) and turn off the ignition before
leaving the vehicle. ACC Override
If using the accelerator pedal while ACC is
active, the ACC indicator turns blue on the
instrument cluster and in the HUD,
if equipped, to indicate that automatic
braking will not occur. ACC will resume
operation when the accelerator pedal is not
being pressed.
{Warning
The ACC will not automatically apply the
brakes if your foot is resting on the
accelerator pedal. You could crash into a
vehicle ahead of you.
Curves in the Road
{Warning
On curves, ACC may not detect a vehicle
ahead in your lane. You could be startled
if the vehicle accelerates up to the set
speed, especially when following a vehicle
exiting or entering exit ramps. You could
lose control of the vehicle or crash. Do
not use ACC while driving on an entrance
or exit ramp. Always be ready to use the
brakes if necessary.
