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 97.
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 97.
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.
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 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!
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!
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.

(Continued)
TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your fascia/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.
WARNING!
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway
severely side to side which will cause loss of control of
the vehicle and trailer. Failure to load trailers heavier in
front is the cause of many trailer collisions.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. 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!

23_LA_OM_EN_USC_t.book Page 101

102STARTING AND OPERATING
Perform the maintenance listed in the “Scheduled
Servicing” Úpage 223. 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. For proper
tire inflation procedures.
 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 253.
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 actu -
ated 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 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.
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!
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 acci -
dent.
 Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional 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.

23_LA_OM_EN_USC_t.book Page 102

STARTING AND OPERATING103
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 after clear from water area.

Four-Pin Connector Seven-Pin Connector

TOWING TIPS
Before towing, practice turning, stopping, and backing up
the trailer in an area located away from heavy traffic.
Automatic Transmission — If Equipped
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 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.
Cruise Control — If Equipped

Do not use on hilly terrain or with heavy loads.
 When using the Cruise Control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
 Use Cruise Control in flat terrain and with light loads to
maximize fuel efficiency.

AutoStick
When using the AutoStick shift control, select the
highest gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or
“3” if needed to maintain the desired speed.
 To prevent excess heat generation, avoid continuous
driving at high RPM. Reduce vehicle speed as neces -
sary to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.
RECREATIONAL TOWING
(BEHIND MOTORHOME)
Recreational towing (with all four wheels on the ground, or
using a tow dolly) is NOT ALLOWED. The only acceptable
method for towing this vehicle (behind another vehicle) is
on a vehicle trailer with all four wheels OFF the ground.
DRIVING TIPS
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 rear (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 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.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe engine, transmission
and/or transfer case damage. Damage from improper
towing is not covered under the New Vehicle Limited
Warranty.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
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.).

(Continued)
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.
CAUTION!
Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
 Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
 Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, transmis -
sion, axle, etc.) for signs of contamination (i.e., fluid
that is milky or foamy in appearance) after driving
through standing water. Do not continue to operate
the vehicle if any fluid appears contaminated, as this
may result in further damage. Such damage is not
covered by the New Vehicle Limited Warranty.
 Getting water inside your vehicle’s engine can cause
it to lock up and stall out, and cause serious internal
damage to the engine. Such damage is not covered
by the New Vehicle Limited Warranty.
CAUTION!

Uconnect Phone allows you to transfer calls between the
system and your mobile phone as you enter or exit your
vehicle and enables you to mute the system's microphone
for private conversation.
The Phone feature is driven through your Bluetooth®
“Hands-Free Profile” mobile phone. Uconnect features
Bluetooth® technology — the global standard that enables
different electronic devices to connect to each other
without wires or a docking station. Ensure you phone is
turned on with Bluetooth® active and has been paired to
the Uconnect system. Up to 10 mobile phones or audio
devices are allowed to be linked to the system. Only one
linked (or paired) mobile phone and one audio device can
be used with the system at a time. Phone Button
The Phone button on your steering wheel is
used to get into the Phone Mode and make
calls, show recent, incoming or outgoing calls,
view phonebook, etc. When you push the
button you will hear a BEEP. The BEEP is your signal to give
a command.
Voice Command Button
The Voice Command button on your steering
wheel is only used for “barge in” and when you
are already in a call or want to make another
call.
The button on your steering wheel is also used to access
the Voice Commands for the Uconnect Voice Command
features if your vehicle is equipped.
Phone Operation
OPERATION
Voice commands can be used to operate the Uconnect
Phone and to navigate its menu structure. Voice
commands are required after most Uconnect Phone
prompts. There are two general methods for how Voice
Command works:

1. Say compound commands like “Call John Smith mobile”.

2. Say the individual commands and allow the system to guide you to complete the task. You will be prompted for a specific command and then
guided through the available options.

Prior to giving a voice command, one must wait for the
beep, which follows the “Listen” prompt or another
prompt.
 For certain operations, compound commands can be
used. For example, instead of saying “Call” and then
“John Smith” and then “mobile”, the following
compound command can be said: “Call John Smith
mobile.”
 For each feature explanation in this section, only the
compound command form of the voice command is
given. You can also break the commands into parts and
say each part of the command when you are asked for
it. For example, you can use the compound command
form voice command “Search for John Smith,” or you
can break the compound command form into two voice
commands: “Search Contacts” and when asked, “John
Smith.” Please remember, the Uconnect Phone works
best when you talk in a normal conversational tone, as
if speaking to someone sitting a few feet/meters away
from you.
NATURAL SPEECH
Your Uconnect Phone Voice system uses a Natural
Language Voice Recognition (VR) engine.
Natural speech allows the user to speak commands in
phrases or complete sentences. The system filters out
certain non-word utterances and sounds such as “ah”
and “eh.” The system handles fill-in words such as “I would
like to”.
WARNING!
ALWAYS drive safely with your hands on the steering
wheel. You have full responsibility and assume all risks
related to the use of the Uconnect features and
applications in this vehicle. Only use Uconnect when it
is safe to do so. Failure to do so may result in an
accident involving serious injury or death.
