For example: If approaching the left side of the
lane the steering wheel will turn to the right.
Lane Sensed (Solid Yellow Inside Line, Solid Yellow Outside Line) With Solid Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left inside lane line flashes
yellow (on/off) while the left outside line
remains solid yellow. The LaneSense telltale
changes from solid yellow to flashing
yellow. At this time torque is applied to the
steering wheel in the opposite direction of
the lane boundary.
For example: If approaching the left side of the
lane the steering wheel will turn to the right.
Lane Approached (Flashing Yellow Inside Line, Solid
Yellow Outside Line) With Flashing Yellow Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure.
Changing LaneSense Status
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (Early/Medium/Late)
that you can configure through the Uconnect
system screen. Refer to “Uconnect Settings” in
“Multimedia” for further information.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph (180 km/h).
Use of the turn signal suppresses the warn -
ings.
The system will not apply torque to the
steering wheel whenever a safety system
engages (Anti-Lock Brakes, Traction Control
System, Electronic Stability Control, Forward
Collision Warning, etc.).

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 Gross vehicle Weight Rating (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. Refer to “Vehicle
Loading/Vehicle Certification Label” in this
chapter for further information.
Gross Trailer Weight (GTW)
The Gross Trailer Weight (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 Axle Weight Rating (GAWR)
The Gross Axle Weight Rating (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. Refer to “Vehicle Loading/
Vehicle Certification Label” in this chapter for
further information.
CAUTION!
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. Also
overloading can shorten the life of your
vehicle.
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.

290STARTING AND OPERATING
Tongue Weight (TW)
The tongue weight 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
The Trailer Sway Control 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.
If equipped, the electronic Trailer Sway Control
(TSC) 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 the most
popular on the market today and they are
commonly 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 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!
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 manufac
-
turer or a reputable Recreational Vehicle
dealer for additional information.

294STARTING AND OPERATING
(Continued)
Make sure loading does not exceed GAWR of
front or rear axles.
GAWR is found on sticker in Driver’s Side
Door Jamb.
Trailer And Tongue Weight
Never exceed the maximum tongue weight
stamped on your bumper or trailer hitch.
Weight Distribution

Consider the following items when computing
the weight on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or
equipment put in or on your vehicle.
The weight of the driver and all passengers. NOTE:
Remember that everything put into or on the
trailer adds to the load on your vehicle. Also,
additional factory-installed options or
dealer-installed options must be considered as
part of the total load on your vehicle. Refer to
the “Tire And Loading Information” placard for
the maximum combined weight of occupants
and cargo for your vehicle.
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”. Refer to “Scheduled
Servicing” in “Servicing And Maintenance” for
the proper maintenance intervals. When towing
a trailer, never exceed the GAWR or GCWR
ratings.
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 colli -
sion.
When hauling cargo or towing a trailer, do
not overload your vehicle or trailer. Over -
loading 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.

20_RU_OM_EN_US_t.book Page 294

STARTING AND OPERATING295
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. Refer to “Tires” in “Servicing And
Maintenance” for proper tire inflation proce -
dures.
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. Refer to
“Tires” in “Servicing And Maintenance” for
the proper inspection procedure.
When replacing tires, refer to “Tires” in
“Servicing And Maintenance” for the proper
tire replacement procedures. Replacing tires
with a higher load carrying capacity will not
increase the vehicle's GVWR and GAWR
limits.
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 inad -
equate 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 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
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.
WARNING! (Continued)
WARNING!
Do not connect trailer brakes to your
vehicle's hydraulic brake lines. It can over -
load 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 stop -
ping 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.

trailer size, stoplights 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 trailer wiring connector from the
vehicle before launching a boat (or any other
device plugged into vehicle’s electrical
connect) into water.
Be sure to reconnect once clear from water
area.

Four-Pin Connector Seven-Pin Connector

CAUTION!
If the trailer weighs more than 1,000 lbs (453

Driving On Slippery Surfaces
Information in this section will aid in safe
controlled launches in adverse conditions.
Acceleration
Rapid acceleration on snow covered, wet, or
other slippery surfaces may cause the driving
wheels to pull erratically to the right or left. This
phenomenon occurs when there is a difference
in the surface traction under the front (driving)
wheels.
Traction
When driving on wet or slushy roads, it is
possible for a wedge of water to build up
between the tire and road surface. This is
hydroplaning and may cause partial or
complete loss of vehicle control and stopping
ability. To reduce this possibility, the following
precautions should be observed:
Slow down during rainstorms or when the
roads are slushy.
Slow down if the road has standing water or
puddles.
Replace the tires when tread wear indicators
first become visible.
Keep tires properly inflated.
Maintain sufficient distance between your
vehicle and the vehicle in front of you to avoid
a collision in a sudden stop.
Driving Through Water
Driving through water more than a few inches/
centimeters deep will require extra caution to
ensure safety and prevent damage to your
vehicle.
WARNING!
Rapid acceleration on slippery surfaces is
dangerous. Unequal traction can cause
sudden pulling of the front wheels. You could
lose control of the vehicle and possibly have a
collision. Accelerate slowly and carefully
whenever there is likely to be poor traction
(ice, snow, wet, mud, loose sand, etc.).
