Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by using
the gear shift +/-. The following summarizes the HDC set
speeds:
HDC Target Set Speeds

• P = No set speed. HDC may be enabled but will not activate.

• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• D = 0.6 mph (1 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If EquippedNOTE:
During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the transmis
-
sion will shift appropriately for the driver-selected set speed
and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available if any of the
following conditions occur:
• The driver overrides HDC set speed with throttle or brake application.
• The vehicle speed exceeds 20 mph (32 km/h) but remains below 40 mph (64 km/h).
• The vehicle is on a downhill grade of insufficient magni -
tude, is on level ground, or is on an uphill grade.
• The vehicle is shifted to park.

SAFETY 207
Disabling HDC
HDC will be deactivated and disabled if any of the following
conditions occur:
• The driver pushes the HDC switch.
• The driveline is shifted out of the 4L Range.
• The park brake is applied.
• The driver door opens.
• The vehicle is driven greater than 20 mph (32 km/h) forgreater than 70 seconds.
• The vehicle is driven greater than 40 mph (64 km/h) (HDC exits immediately).
• HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate and remain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several seconds, then extinguish when the driver pushes the HDC
switch but enable conditions are not met. • The cluster icon and switch lamp will flash for several
seconds, then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
Hill Start Assist (HSA)
The Hill Start Assist (HSA) system is designed to mitigate
roll back from a complete stop while on an incline. If the
driver releases the brake while stopped on an incline, HSA
will continue to hold the brake pressure for a short period. If
the driver does not apply the throttle before this time expires,
the system will release brake pressure and the vehicle will
roll down the hill as normal.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.4
2020_DT_1500_OM_US.book Page 207

208 SAFETY
The following conditions must be met in order for HSA to
activate:
• The feature must be enabled.
• The vehicle must be stopped.
• The park brake must be off.
• The driver door must be closed.
• The vehicle must be on a sufficient grade.
• The gear selection must match vehicle uphill direction (i.e.,vehicle facing uphill is in forward gear; vehicle backing
uphill is in REVERSE (R) gear).
• HSA will work in REVERSE (R) gear and all forward gears. The system will not activate if the transmission is in PARK
(P) or NEUTRAL (N). For vehicles equipped with a
manual transmission, if the clutch is pressed, HSA will
remain active.WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur,
such as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active
driving involvement. It is always the driver’s
responsibility to be attentive to distance to other
vehicles, people, and objects, and most importantly
brake operation to ensure safe operation of the vehicle
under all road conditions. Your complete attention is
always required while driving to maintain safe control of
your vehicle. Failure to follow these warnings can result
in a collision or serious personal injury.

SAFETY 217
When RCP is on and the vehicle is in REVERSE (R), the
driver is alerted using both the visual and audible alarms,
including reducing the radio volume.
Modes Of Operation
Three selectable modes of operation are available in the
Uconnect System.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the BSM system
will provide a visual alert in the appropriate side viewmirror based on a detected object. However, when the
system is operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and audible alerts
when a detected object is present. Whenever an audible alert
is requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode, the
BSM system will provide a visual alert in the appropriate
side view mirror based on a detected object. If the turn signal
is then activated, and it corresponds to an alert present on
that side of the vehicle, an audible chime will also be
sounded. Whenever a turn signal and detected object are
present on the same side at the same time, both the visual
and audible alerts will be issued. In addition to the audible
alert the radio (if on) will also be muted.
NOTE:
Whenever an audible alert is requested by the BSM system,
the radio is also muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio is
also muted. Turn/hazard signal status is ignored; the RCP
state always requests the chime.
WARNING!
Rear Cross Path Detection (RCP) is not a back up aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using RCP.
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. Failure to do so can result in serious
injury or death.

Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) with Mitigation
system provides the driver with audible warnings, visual
warnings (within the instrument cluster display), and may
apply a brake jerk to warn the driver when it detects a poten -
tial frontal collision. The warnings and limited braking are
intended to provide the driver with enough time to react,
avoid or mitigate the potential collision. NOTE:
FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings as
well as a possible brake jerk warning.
If the driver does not take action based upon these progres
-
sive warnings, then the system will provide a limited level of
active braking to help slow the vehicle and mitigate the
potential forward collision. If the driver reacts to the warn -
ings by braking and the system determines that the driver
intends to avoid the collision by braking but has not applied
sufficient brake force, the system will compensate and
provide additional brake force as required.
If a FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum braking possible to mitigate the potential forward collision.
If the Forward Collision Warning with Mitigation event
stops the vehicle completely, the system will hold the vehicle
at standstill for two seconds and then release the brakes.

SAFETY 223
FCW Message
When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message will
be deactivated.
NOTE:

• The minimum speed for FCW activation is 3 mph (5 km/h).

• The FCW alerts may be triggered on objects other than vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of normal
FCW activation and functionality. • It is unsafe to test the FCW system. To prevent such misuse
of the system, after four Active Braking events within a
key cycle, the Active Braking portion of FCW will be deac -
tivated until the next key cycle.
• The FCW system is intended for on-road use only. If the vehicle is taken off-road, the FCW system should be deac -
tivated to prevent unnecessary warnings to the surround -
ings.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow this
warning could lead to serious injury or death.4

• The TPMS is not a substitute for proper tire maintenance,and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and the TPMS will monitor the actual tire pressure in the tire.
Tire Pressure Monitor Display The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each wheel
as part of the valve stem, transmit tire pressure readings to
the receiver module.
NOTE:
It is particularly important for you to check the tire pressure
in all of the tires on your vehicle monthly and to maintain the
proper pressure.
The TPMS consists of the following components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
