instrument cluster displays the “Sensed Vehicle
Indicator” icon, and the system adjusts vehicle
speed automatically to maintain the distance
setting, regardless of the set speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor -
mation on ACC Activation).
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.

Brake Alert

NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.
OVERTAKE AID
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal (Lane Change Assist feature included) and will only be active when passing on the left
hand side. Switching lanes will not impact the
ACC system if the driver is already traveling at
the set speed.
ACC OPERATION AT STOP
If the ACC system brings your vehicle to a
standstill while following a target vehicle, if the
target vehicle starts moving within two seconds
of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a
standstill, the ACC with Stop system will cancel
and the brakes will release. A cancel message
will display on the instrument cluster display
and produce a warning chime. Driver
intervention will be required at this moment.
While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or
the driver door is opened, the ACC with Stop
system will cancel and the brakes will release. A
cancel message will display on the instrument
cluster display and produce a warning chime.
Driver intervention will be required at this
moment.

Using ACC On Hills
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 hills, ACC performance may be
limited.

ACC Hill Example

Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you are
traveling. In the illustration shown, ACC has not
yet detected the vehicle changing lanes and it
may not detect the vehicle until it's too late for
the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane.
There may not be sufficient distance to the
lane-changing vehicle. Always be attentive and
ready to apply the brakes if necessary.
Lane Changing Example

Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.

Lane Sensed (Solid Yellow Lines/Solid Yellow Telltale)

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left thick lane line flashes
yellow (on/off) and the left thin 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.

have exceeded either GAWR, but the total load
is within the specified GVWR, you must
redistribute the weight. Improper weight
distribution can have an adverse effect on the
way your vehicle steers and handles and the
way the brakes operate.
NOTE:
Refer to the “Vehicle Certification Label”
affixed to the rear of the driver's door for your
vehicle's GVWR and GAWRs.
Refer to the “Tire Placard” for your vehicle's
proper tire pressure.
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.
Refer to “Loading” in “Starting And Operating”
for further information.
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. Refer to
“Loading” in “Starting And Operating” for
further information.
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.

20_LX_OM_EN_USC_t.book Page 191

192STARTING 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 (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.
If equipped, the electronic 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.

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.
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.
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 diffi -
cult 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. 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.
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. 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 :
Max loading as defined on the “Tire and
Loading Information” placard.
GTW
GAWR
Tongue weight rating for the trailer
hitch utilized.
WARNING! (Continued)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.

20_LX_OM_EN_USC_t.book Page 195

196STARTING AND OPERATING
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).
Towing Requirements — Trailer Lights And
Wiring
Whenever you pull a trailer, regardless of the
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 after clear from water
area.
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.
CAUTION!
If the trailer weighs more than 1,000 lbs
(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.

TOWING TIPS
Before setting out on a trip, practice turning,
stopping, and backing up the trailer in an area
located away from heavy traffic.
Automatic Transmission
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control (if equipped)
to manually select a lower gear.
NOTE:
Using a lower gear while operating the vehicle
under heavy loading conditions will improve
performance and extend transmission life by
reducing excessive shifting and heat buildup.
This action will also provide better engine
braking.
Speed Control — If Equipped
Do not use on hilly terrain or with heavy
loads.
When using the Speed Control, if you experi-
ence speed drops greater than 10 mph
(16 km/h), disengage until you can get back
to cruising speed.
Use Speed Control in flat terrain and with
light loads to maximize fuel efficiency.

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
known as 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 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.
Your vehicle may be equipped with a Limited
Slip Differential (LSD) that reduces, but does
not eliminate, the amount of wheel slip across a
given axle for improved handling.
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.
Flowing/Rising Water Shallow Standing Water
Although your vehicle is capable of driving
through shallow standing water, consider
the following Warnings and Cautions before
doing so.
WARNING!
Do not drive on or across a road or path
where water is flowing and/or rising (as in
storm run-off). Flowing water can wear away
the road or path's surface and cause your
vehicle to sink into deeper water.
Furthermore, flowing and/or rising water can
carry your vehicle away swiftly. Failure to
follow this warning may result in injuries that
are serious or fatal to you, your passengers,
and others around you.
WARNING!
Driving through standing water limits your
vehicle’s traction capabilities. Do not
exceed 5 mph (8 km/h) when driving
through standing water.
Driving through standing water limits your
vehicle’s braking capabilities, which
increases stopping distances. Therefore,
after driving through standing water, drive
slowly and lightly press on the brake pedal
several times to dry the brakes.
Failure to follow these warnings may result
in injuries that are serious or fatal to you,
your passengers, and others around you.
