STARTING AND OPERATING145
(Continued)
To Deactivate
A tap on the brake pedal, pushing the CANC (cancel)
button, or normal brake pressure while slowing the vehicle
will deactivate the Cruise Control system without erasing
the set speed from memory.
The following conditions will also deactivate the Cruise
Control system without erasing the set speed from
memory:
Vehicle parking brake is applied
Stability event occurs
Gear selector is moved out of DRIVE
Engine overspeed occurs
Pushing the on/off button or placing the ignition in the OFF
position, erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC)
Adaptive Cruise Control (ACC) increases the driving
convenience provided by Cruise Control while traveling on
highways and major roadways. However, it is not a safety
system and not designed to prevent collisions. The Cruise
Control function performs differently
Úpage 143.
ACC will allow you to keep Cruise Control engaged in light
to moderate traffic conditions without the constant need
to reset your speed. ACC utilizes a radar sensor and a
forward facing camera designed to detect a vehicle
directly ahead of you to maintain a set speed.
NOTE:
If the ACC sensor detects a vehicle ahead, ACC will
apply limited braking or acceleration (not to exceed the
original set speed) automatically to maintain a preset
following distance, while matching the speed of the
vehicle ahead.
Any chassis/suspension or tire size modifications to
the vehicle will affect the performance of the Adaptive
Cruise Control and Forward Collision Warning system.
Fixed Speed Cruise Control (ACC not enabled) will not
detect vehicles directly ahead of you. Always be aware
of the feature selected
Úpage 402.
WARNING!
Adaptive Cruise Control (ACC) is a convenience
system. It is not a substitute for active driver involve -
ment. It is always the driver’s responsibility to be
attentive of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle ahead 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 colli -
sion and death or serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming vehi -
cles, and stationary objects (e.g., a stopped
vehicle in a traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather condi -
tions into account, and may be limited upon
adverse sight distance conditions.
Does not always fully recognize complex driving
conditions, which can result in wrong or missing
distance warnings.
Will bring your vehicle to a complete stop while
following a vehicle ahead and hold your vehicle
for approximately three minutes in the stop posi -
tion. If the vehicle ahead does not start moving
within three minutes the parking brake will be
activated, and the ACC system will be canceled.
You should not utilize the ACC system:
When driving in fog, heavy rain, heavy snow, sleet,
heavy traffic, and complex driving situations (i.e., in
highway construction zones).
When entering a turn lane or highway off-ramp; when
driving on roads that are winding, icy, snow-covered,
slippery, or have steep uphill or downhill slopes.
When towing a trailer up or down steep slopes.
When circumstances do not allow safe driving at a
constant speed.
WARNING!

STARTING AND OPERATING151
SERVICE ACC/FCW WARNING
If the system turns off, and the instrument cluster displays
“ACC/FCW Unavailable Service Required” or “Cruise/FCW
Unavailable Service Required”, there may be an internal
system fault or a temporary malfunction that limits ACC
functionality. Although the vehicle is still drivable under
normal conditions, ACC will be temporarily unavailable.
If this occurs, try activating ACC again later, following an
ignition cycle. If the problem persists, see an authorized
dealer.
Precautions While Driving With ACC
NOTE:
Aftermarket add-ons such as snowplows, lift kits, and
brush/grille bars can hinder module performance.
Ensure the radar/camera has no obstructions in the
field of view.
Height modifications can limit module performance
and functionality.
Do not put stickers or easy passes over the camera/
radar field of view.
Any modifications to the vehicle that may obstruct the
field of view of the radar/camera are not recom -
mended.
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or
unexpectedly. The driver needs to stay alert and may need
to intervene. The following are examples of these types of
situations:
TOWING A TRAILER
ACC while towing a trailer is recommended only with an
Integrated Trailer Brake Controller. Aftermarket trailer
brake controllers will not activate the trailer brakes when
ACC is braking.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Offset Driving Condition Example
TURNS AND BENDS
When driving on a curve with ACC engaged, the system
may increase or decrease the vehicle speed for stability,
with no vehicle ahead detected. Once the vehicle is out of
the curve, the system will resume your original set speed.
This is a part of normal ACC system functionality.
NOTE:On tight turns ACC performance may be limited.
USING ACC ON HILLS
ACC performance may be limited when driving on hills.
ACC may not detect a vehicle in your lane depending on
the speed, vehicle load, traffic conditions, and the
steepness of the hill.

STARTING AND OPERATING153
NOTE:
The driver can disable the automatic braking function by
turning ParkSense off via the ParkSense switch. The
driver can also override automatic braking by changing
the gear or by pressing the gas pedal over 90% of its
capacity during the braking event.
Automatic brakes will not be available if the vehicle is in
4WD Low.
Automatic brakes will not be available if there is a fault
in the brake module.
Automatic brakes will not be available if there is a faulted
condition detected with the ParkSense Park Assist
system or the Braking System.
The automatic braking function may only be applied if
the vehicle deceleration is not enough to avoid colliding
with a detected obstacle.
The automatic braking function may not be applied fast
enough for obstacles that move toward the rear of the
vehicle from the left and/or right sides.
The automatic braking function can be enabled/
disabled from the Customer Programmable Features
section of the Uconnect system.
ParkSense will retain its last known configuration state
for the automatic braking function through ignition
cycles.
Trailer hitch ball assembly may cause false braking
events if left attached after towing.
The automatic braking function is intended to assist the
driver in avoiding possible collisions with detected obstacles
when backing up in REVERSE gear.
NOTE:
The system is designed to assist the driver and not to
substitute the driver.
The driver must stay in full control of the vehicle's accel -
eration and braking and is responsible for the vehicle's
movements.
For limitations of this system and usage precautions, see
Ú
page 156.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
placed in the ON/RUN position.
ParkSense can be active only when the gear selector is in
REVERSE or DRIVE. If ParkSense is enabled while in one of
these gears, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or above. A warning will appear in the instrument cluster
display indicating the vehicle speed is above ParkSense
operating speed while in REVERSE. The system will become
active again if the vehicle speed is decreased to less than
approximately 6 mph (9 km/h).
PARKSENSE SENSORS
The four ParkSense sensors (six if equipped with Active
Parksense), located in the front fascia/bumper, monitor
the area in front of the vehicle that is within the sensors’
field of view, and the four ParkSense sensors, located in
the rear fascia/bumper, monitor the area behind the
vehicle that is within the sensors’ field of view. The front
sensors can detect obstacles from approximately
12 inches (30 cm) up to 47 inches (120 cm) from the front fascia/bumper. The rear sensors can detect obstacles from approximately
12 inches (30 cm) up to 79 inches (200 cm). These
distances depend on the location, type and orientation of
the obstacle in the horizontal direction.
PARKSENSE WARNING DISPLAY
The ParkSense Warning screen is located within the
instrument cluster display Úpage 98. It provides visual
warnings to indicate the distance between the rear fascia/
bumper and/or front fascia/bumper and the detected
obstacle.
PARKSENSE DISPLAY
The warning display will turn on indicating the system status
when the vehicle is in REVERSE or when the vehicle is in
DRIVE and an obstacle has been detected.
The system will indicate a detected obstacle by showing a
single arc in the left, right, or center regions based on the
obstacle’s distance and location relative to the vehicle.
If an obstacle is detected in the center front region, the
display will show a single solid arc in the center front region
with no chime. As the vehicle moves closer to the obstacle,
the display will show the single arc moving closer to the
vehicle and a fast chime will be heard and will change from
fast to continuous.
If an obstacle is detected in the left and/or right front region,
the display will show a single flashing arc in the left and/or
right front region and will produce a fast chime. As the
vehicle moves closer to the obstacle, the display will show
the single arc moving closer to the vehicle and the tone will
change from fast to continuous.

STARTING AND OPERATING157
When you move the gear selector to the REVERSE posi -
tion and Front or Rear ParkSense is turned off, the
instrument cluster display will show a vehicle graphic
with "OFF" in the corresponding side. This vehicle
graphic will be displayed for as long as the vehicle is in
REVERSE.
ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle is
behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense
system off if obstacles such as bicycle carriers, trailer
hitches, etc. are placed near the rear fascia/bumper.
Failure to do so can result in the system misinter -
preting a close obstacle as a sensor problem, causing
the “PARKSENSE UNAVAILABLE SERVICE REQUIRED”
message to be appear in the instrument cluster
display.
ParkSense should be disabled when the tailgate is in
the lowered or open position. A lowered tailgate could
provide a false indication that an obstacle is behind the
vehicle and could also cause a false braking event.
The Rear ParkSense system will automatically disable
when the system detects that a trailer with trailer
brakes has been connected to the Integrated Trailer
Brake Module.
The Front ParkSense system will automatically disable
if a snowplow has been connected to the vehicle.
PARKSENSE ACTIVE PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space,
providing audible/visual instructions through the
instrument cluster display, and controlling the steering
wheel. The ParkSense Active Park Assist system is defined
as “semi-automatic” since the driver maintains control of
the accelerator, gear selector and brakes. Depending on
the driver's parking maneuver selection, the ParkSense
Active Park Assist system is capable of maneuvering a
vehicle into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
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 respon -
sible 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 recommended
that the ball mount and hitch ball assembly be
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/bumper when the vehicle sounds the
continuous tone. Also, the sensors could detect the
ball mount and hitch ball assembly, depending on its
size and shape, and give a false indication that an
obstacle is behind the vehicle, and could cause false
braking.
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 Park -
Sense 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 Park -
Sense.

172STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear Gross Axle Weight Rating (GAWR). Total load must be
limited so GVWR and front and rear GAWR are not
exceeded.
PAYLOAD
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the driver,
all passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR.
TIRE SIZE
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full Gross Axle Weight Rating
(GAWR).
CURB WEIGHT
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation. The entire vehicle should first be weighed on a commercial
scale to ensure that the Gross Vehicle Weight Rating
(GVWR) has not been exceeded. The weight on the front
and rear of the vehicle should then be determined
separately to be sure that the load is properly distributed
over the front and rear axle. Weighing the vehicle may
show that the Gross Axle Weight Rating (GAWR) of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be
shifted from front to rear or rear to front as appropriate
until the specified weight limitations are met. Store the
heavier items down low and be sure that the weight is
distributed equally. Stow all loose items securely before
driving.
Improper weight distributions can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

STARTING AND OPERATING173
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 172.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its “loaded and
ready for operation” condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 172.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch ball by
the trailer. You must consider this as part of the load on
your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
The electronic TSC (If equipped) recognizes a swaying
trailer and automatically applies individual wheel brakes
and/or reduces engine power to attempt to eliminate the
trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some
other connecting point of the vehicle. These kinds of
hitches are commonly used to tow small and medium
sized trailers.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.

23_DT_OM_EN_USC_t.book Page 173
Page 176 of 416

174STARTING AND OPERATING
Weight-Distributing Hitch
A weight-distributing system works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer's directions, it provides
for a more level ride, offering more consistent steering and
brake control, thereby enhancing towing safety. The
addition of a friction/hydraulic sway control also dampens
sway caused by traffic and crosswinds and contributes
positively to tow vehicle and trailer stability. Trailer Sway
Control and a weight-distributing (load equalizing) hitch
are recommended for heavier Tongue Weights (TW) and
may be required depending on vehicle and trailer
configuration/loading to comply with GAWR requirements.
Without Weight-Distributing Hitch (Incorrect) With Weight-Distributing Hitch (Correct)
Improper Adjustment Of Weight-Distributing Hitch (Incorrect)
WARNING!
An improperly adjusted weight-distributing hitch
system may reduce handling, stability and braking
performance and could result in a collision.
Weight-distributing systems may not be compatible
with surge brake couplers. Consult with your hitch
and trailer manufacturer or a reputable Recreational
Vehicle dealer for additional information.

RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT
Towing With Air Suspension — If Equipped
1. Verify that the vehicle is at the normal ride height.
NOTE:The vehicle must remain in the engine run position with all
doors closed while attaching a trailer for proper leveling of
the air suspension system.
2. Position the truck to be ready to connect to the trailer
(do not connect the trailer).
3. Enable tire jack mode through the instrument cluster or touchscreen radio settings. Tire jack mode will be
canceled and the procedure must be restarted if the
vehicle is driven at speeds above 5 mph (8 km/h).
4. Measure the height from the top of the front wheel opening on the fender to ground; this is height H1.
Measuring Height (H)
5. Attach the trailer to the vehicle without the weight-distributing bars connected.
6. Measure the height from the top of the front wheel opening on the fender to the ground; this is height H2.
7. Install and adjust the tension in the weight-distributing bars per the manufacturer’s
recommendations so that the height of the front
fender is approximately (H2-H1)/3+H1
(about 1/3 the difference between H2 and H1 above
normal ride height [H1]). 8. Use the instrument cluster or touchscreen radio
settings and switch off tire jack mode. Make sure the
truck returns to normal ride height. Perform a visual
inspection of the trailer and weight-distributing hitch
to confirm the manufacturer’s recommendations
have been met.
9. The truck can now be driven.
NOTE:For all towing conditions, we recommend towing with
Tow/Haul mode engaged.

STARTING AND OPERATING179
(Continued)
Some trailers (such as boat trailers) will need to
recalibrate while loaded and unloaded.
NOTE:
The system may not detect a trailer in low light condi -
tions. In sunny conditions, the performance may be
degraded as shadows pass over the trailer.
The driver is always responsible for safe operation of
truck and trailer.
The driver is always in control of the truck as well as the
trailer and is responsible for controlling the throttle and
brakes.
The system may not function when the camera lens is
blocked, blurred (covered with water, snow, ice, dirt,
etc) and will not work unless the tailgate is upright and
fully latched.
TOWING REQUIREMENTS
To promote proper break-in of your new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing section for the proper maintenance intervals
Úpage 333. When towing a trailer, never exceed the
GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
Do not drive more than 50 mph (80 km/h) when towing
while using a full size spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
Check the trailer tires for proper tire inflation pressures
before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
For further information
Úpage 370.
CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
"chock" the trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch utilized
