NOTE:
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 transmission 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 any time.
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 insuffi -
cient magnitude, is on level ground, or is on
an uphill grade.

SAFETY317
Hill Start Assist (HSA)
HSA 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.
The following conditions must be met in order
for HSA to activate:
The feature must be enabled.
The vehicle must be stopped.
The parking 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 gear).
HSA will work in REVERSE gear and all
forward gears. The system will not activate if
the transmission is in PARK or NEUTRAL.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using Uconnect Settings
Úpage 237.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.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.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated
and deactivated with the brake switch. If
so, there may not be enough brake pres -
sure to hold both the vehicle and the trailer
on a hill when the brake pedal is released.
In order to avoid rolling down an incline
while resuming acceleration, manually acti -
vate the trailer brake or apply more vehicle
brake pressure prior to releasing the brake
pedal.
HSA is not a parking brake. Always apply
the parking brake fully when exiting your
vehicle. Also, be certain to place the trans -
mission in PARK.
Failure to follow these warnings can result
in a collision or serious personal injury.

SAFETY323
a trailer will be detected using the blind spot
radar within 90 seconds of forward move -
ment of the vehicle. The vehicle must be
moving above 6 mph (10 km/h) to activate the feature. Once the trailer has been
detected, the system will default to the
maximum blind spot zone until the length has
been verified. You will see “Auto” in the
instrument panel cluster .
Maximum Mode — When “Max Mode” is
selected, the system will default to the
maximum blind spot zone regardless of what
size trailer is attached .
NOTE:
Selected setting is stored when the ignition is
placed in the OFF position. To change this
setting, it must be selected through the
Uconnect settings Ú page 237.
Trailer Length Detection
Once the trailer presence has been established,
the trailer length will be established (by making
a 90 degree turn) and then the trailer length
category (example 10-20 ft (3 m to 6 m)) will be
displayed. This can take up to 30 seconds after
completing the turn. NOTE:
During the same ignition cycle, if the vehicle is
at a standstill for a minimum of 90 seconds, a
new “trailer detection request” is enabled by
the system once the vehicle resumes motion.
Maximum length supported by the Trailer Merge
Assist feature is 39.5 ft (12 m). Trailer length is
considered the forward most portion of the
trailer hitch to the rearward most portion of the
body, fascia/bumper, or ramp of the trailer.
Maximum width supported by the Trailer Merge
Assist feature is 8.5 ft (2.59 m). Trailer width is
measured at the widest portion of the trailer
and may include wheels, tires, finders, or rails.
NOTE:
Fifth wheel or gooseneck trailers are not
supported by Trailer Merge Assist.
NOTE:
The ability to detect a trailer may be degraded in
crowded or busy environments. Busy parking
lots, narrow areas surrounded with trees, or any
other crowded area may prevent the radar
sensors from being able to adequately detect
the trailer. The system will try to detect a trailer
at every ignition cycle or 90 seconds of stand
-
still.
Trailer Length Detection

Trailer length will be identified and placed into
one of the following categories:
Trailer length up to 10 ft (3 m) — Blind spot
zone will be adjusted to 10 ft (3 m) .
Trailer length between 10 ft to 20 ft (3 m to
6 m) — Blind spot zone will be adjusted to
20 ft (6 m) .
Trailer length between 20 ft to 30 ft (6 m to
9 m) — Blind spot zone will be adjusted to
30 ft (9 m) .

IESEL ENGINE)
This engine meets all required diesel engine
emissions standards. To achieve these
emissions standards, your vehicle is equipped
with a state-of-the-art engine and exhaust
system. These systems are seamlessly
integrated into your vehicle and managed by
the Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the
exhaust system’s catalyst to trap and burn
Particulate Matter (PM) pollutants, with no input
or interaction on your part.
Additionally, your vehicle has the ability to alert
you to additional maintenance required on your
vehicle or engine Ú page 114.WARNING!
Do not open the high pressure fuel system
with the engine running. Engine operation
causes high fuel pressure. High pressure fuel
spray can cause serious injury or death.
CAUTION!
The starter motor will engage for
approximately 30 seconds at a time. Allow
two minutes between cranking intervals.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable under
certain conditions and be hazardous or
explosive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or
gasoline, the use of these fuels can cause
damage to the fuel system.
WARNING!
A hot exhaust system can start a fire if you
park over materials that can burn, such as
grass or leaves, and those items that come
into contact with your exhaust system. Do not
park or operate your vehicle in areas where
your exhaust system can contact anything
that can burn.
