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 the new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing
Úpage 309. When towing a trailer, never
exceed the GAWR or GCWR ratings.
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.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
(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.

186STARTING AND OPERATING
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 349.
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).
Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and Electric
Over Hydraulic (EOH) trailer brakes. The controller is
located below the instrument panel on the right side of the
steering column.
NOTE:This module has been designed and verified with electric
trailer brakes and EOH systems. Some previous EOH
systems may not be compatible with ITBM.

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!
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_WS_OM_EN_USC_t.book Page 186

STARTING AND OPERATING187

Integrated Trailer Brake Module (ITBM)

The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the
tow vehicle's brakes. If the manual brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle's brake lamps will come on
when either vehicle braking or manual trailer brakes are
applied. Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN
setting for 10 seconds and the Trailer Brake Status
Indicator Light will not be displayed.
If a fault is detected in the trailer wiring or the ITBM, the
Trailer Brake Status Indicator Light will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or
decreased to a minimum of 0 (no trailer braking).
GAIN
The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.
Adjusting GAIN
NOTE:This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).

1. Make sure the trailer brakes are in good working condition, functioning normally and properly
adjusted. See a trailer dealer if necessary.

2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's
instructions. 3. When a trailer with electric/EOH brakes is plugged in,
the trailer connected message should appear in the
instrument cluster display (if the connection is not
recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and the
correct type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the “Trailer Brake Type” appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type appears
on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier trailer,
trailer wheel lockup may not be attainable even with the
maximum GAIN setting of 10.

Úpage 99.
NOTE:
An aftermarket controller may be available for use with
trailers with air or EOH trailer brake systems. To deter -
mine the type of brakes on your trailer and the avail -
ability of controllers, check with your trailer
manufacturer or dealer.
 Removal of the ITBM will cause errors and it may cause
damage to the electrical system and electronic
modules of the vehicle. See an authorized dealer if an
aftermarket module is to be installed.
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 the vehicle's electrical
connectors) before launching a boat into water.
 Be sure to reconnect once clear from water area.

Four-Pin Connector

WARNING!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
personal injury.
CAUTION!
Connecting a trailer that is not compatible with the
ITBM system may result in reduced or complete loss of
trailer braking. There may be an increase in stopping
distance or trailer instability which could result in
damage to your vehicle, trailer, or other property.

TOWING TIPS
Before towing, practice turning, stopping, and backing up
the trailer in an area located away from heavy traffic. If
equipped with Quadra-Lift air suspension, the automatic
Entry/Exit feature may be disabled through the Uconnect
Touchscreen Radio to prevent vehicle and trailer
movement when gear selector is moved to PARK.
Automatic Transmission
Select the DRIVE (D) 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 Electronic Range Select
(ERS) 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
build-up. 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.

DRIVING TIPS
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
characteristics give them a higher center of gravity than
conventional passenger cars.
An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems. They
are not designed for cornering at the same speeds as
conventional passenger cars any more than low-slung
sports cars are designed to perform satisfactorily in
off-road conditions. Avoid sharp turns or abrupt
maneuvers. As with other vehicles of this type, failure to
operate this vehicle correctly may result in loss of control
or vehicle rollover.
OFF-ROAD DRIVING TIPS
Quadra-Lift — If Equipped
When off-roading, it is recommended that the lowest
useable vehicle height that will clear the current obstacle
or terrain be selected. The vehicle height should then be
raised as required by the changes in terrain.
The Selec-Terrain switch will automatically change the
vehicle to the optimized height based on the Selec-Terrain
switch position. The vehicle height can be changed from
the default height for each Selec-Terrain mode by normal
use of the air suspension switches
