Selection Of The Maneuver Side
Use the direction indicators to choose the direction
that you want to perform the maneuver. Use the
right arrow indicator to perform the maneuver to
the right side and use the left arrow indicator to
perform the maneuver to the left.
During the maneuver, the system instructs the
driver to shift to REVERSE, and operate the turn
signal in the direction you want to exit. Let go of the
steering wheel and use the brake or accelerator
pedals as instructed, while the system handles the
steering automatically for exiting the parking
space. If the driver continues to carry out a
voluntary or involuntary action on the steering
wheel during the exit maneuver (touching or
holding the steering wheel to prevent its
movement), the maneuver will be interrupted.

End Of Maneuver
The semi-automatic maneuver ends when the
display shows the message of a completed
maneuver. At the end of the maneuver, the system
gives back the vehicle control to the driver.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and to measure vehicle position within
the lane boundaries. It also uses the Blind Spot
Monitoring (BSM) sensors to detect vehicles in
adjacent lanes while the driver is preparing to
change lanes. The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle approaches (or crosses) the lane marking
with no turn signal applied, and the blind spot zone
is not occupied, the ALM system provides warnings
to prompt the driver to remain within the lane
boundaries. These warnings include a visual
warning in the instrument cluster along with
steering assist torque (if configured in Uconnect
Settings).
If the driver crosses the lane marking, the system
will either guide the vehicle back to the center of
the lane, provide a vibration in the steering wheel,
or both, depending on radio settings.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change, and a vehicle is detected in the BSM zone
on that side of the vehicle, the ALM system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.NOTE:
The system will suppress visual warnings,
steering vibration (if selected in radio settings),
and steering assistance (if selected in radio
settings) when the driver activates the turn
signal, the blind spot zone is clear of vehicles,
and a lane change is occurring.

NOTE:
The Active Lane Management system operates
with similar behavior for a right lane departure.
If the turn signal is activated, and the vehicle
begins to depart the lane at the same time the
Blind Spot Monitoring (BSM) system detects
another vehicle in the BSM zones, the system
will provide a haptic steering wheel vibration
and/or steering assist torque (if programmed in
Uconnect Settings).

The Night Vision alert status telltale will
be gray when the warnings are
suppressed. The telltale will also turn
gray to indicate that the alerts are
suppressed due to environmental factors (e.g.
daylight hours, external temperature is greater
than 86°F (30°C)) or if the gear selector is in
REVERSE. When the Night Vision alerts are active,
the telltale will be green Ú page 108.
Camera Washers
When the front window washer is activated, the
Night Vision camera will also be washed
Ú page 64.
DETECTION RANGE
The system can detect people 4 ft (1.25 m) tall or
greater in the upright position. The system can also
detect animals that are four-legged and 3 ft (1 m)
tall or greater in the upright position.
The detection distance for the system is between
26 ft (8 m) and 328 ft (100 m) from the front of the
vehicle.
The system may not be able to detect pedestrians
or animals in the following situations:
Pedestrian/animal is outside of the detection
range
Pedestrian/animal is fully or partially covered
Pedestrian/animal does not reach the minimum
detection height
NOTE:Other objects on the road that meet the height/
shape/temperature (e.g. sun exposure) of pedes -
trians/animals may be detected and classified as
targets.
WARNING!
Do not jerk the steering wheel in response to
a warning.
Never attempt to swerve around animals if
doing so would endanger you or others.
Do not stare at the image while driving. You
could crash and you or others could be
injured.
The Night Vision system only provides alerts to
objects of interest and cannot serve as a
substitute for the driver’s personal judgment.
The warnings are meant to direct your atten-
tion to the detected objects, but the Night
Vision system does not automatically brake
the vehicle and may not provide a warning
with enough time to help avoid a crash.
Warnings are only provided if a pedestrian or
large animal is detected by the system.
It is always the driver’s responsibility to be
attentive of road, traffic, and weather condi -
tions, vehicle speed, distance to the vehicle
ahead, and most importantly, brake opera -
tion, 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.

STARTING AND OPERATING185
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full 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 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 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.
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 Ú
page 184.
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.
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.
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.

23_WL_OM_EN_USC_t.book Page 185

186STARTING AND OPERATING
(Continued)
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 184.
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 used to tow small and
medium sized trailers.
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
(TSC) 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 Gross Axle Weight Rating (GAWR)
requirements.
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.
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.

RECOMMENDED DISTRIBUTION HITCH
ADJUSTMENT

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 vehicle to be ready to connect to the trailer (do not connect the trailer). 3. For vehicles equipped with Quadra-Lift air
suspension, use the touchscreen radio
settings to enable Tire/Jack mode. Tire/Jack
mode will be canceled and the procedure must
be restarted if the vehicle is driven at speeds
above 5mph (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 distribution 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)/2+H1
(about 1/2 the difference between H2 and H1
above Normal Ride Height [H1]).
8. Use the 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
manufacturers’ recommendations have been
met.
9. The vehicle can now be driven.
An improperly adjusted weight-distributing
hitch system may reduce handling, stability,
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.

TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the Scheduled
Servicing Ú
page 330. 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 Ú page 374.
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
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or
damage to brakes, axle, engine, transmission,
steering, suspension, 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 (P). For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL (N). 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
WARNING!
GAWR
Tongue weight rating for the trailer hitch
utilized
WARNING!

23_WL_OM_EN_USC_t.book Page 192

STARTING AND OPERATING193
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system
or vacuum system of your vehicle with that of
the trailer. This could cause inadequate braking
and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer with
electronically actuated brakes. When towing a
trailer equipped with a hydraulic surge actuated
brake system, an electronic brake controller is
not required.
Trailer brakes are recommended for trailers
over 1,000 lb (453 kg) and required for trailers
in excess of 2,000 lb (907 kg).
Towing Requirements — Trailer Lights And
Wiring
Whenever pulling a trailer, regardless of the trailer
size, stop lights and turn signals on the trailer are
required for motoring safety.
The Trailer Tow Package may include a four- and
seven-pin wiring harness. Use a factory approved
trailer harness and connector.
NOTE:Do not cut or splice wiring into the vehicle’s wiring
harness.
The electrical connections are all complete to the
vehicle but you must mate the harness to a trailer
connector. Refer to the following illustrations.
NOTE:
Disconnect the trailer wiring connector from the
vehicle (or any other device plugged into
vehicle’s electrical connectors) before
launching a boat into water.
Be sure to reconnect once clear from water
area.

Four-Pin Connector

WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your
brake system and cause it to fail. You might
not have brakes when you need them and
could have an accident.
Towing any trailer will increase your stopping
distance. When towing, you should allow for
additional space between your vehicle and the
vehicle in front of you. Failure to do so could
result in an accident.
CAUTION!

If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they
should be of adequate capacity. Failure to do this
could lead to accelerated brake lining wear, higher
brake pedal effort, and longer stopping distances.
