(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.
Display Messages
The trailer brake control interacts with the
instrument cluster display. Display messages,
along with a single chime, will be displayed when a
malfunction is determined in the trailer
connection, trailer brake control, or on the trailer
Ú page 83.
NOTE:
An aftermarket controller may be available for
use with trailers with air or EOH trailer brake
systems. To determine the type of brakes on
your trailer and the availability 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 autho -
rized dealer if an aftermarket module is to be
installed.
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.

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 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

TOWING TIPS
Before towing, practice turning, stopping, and
backing up the trailer in an area located away from
heavy traffic.
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 AutoStick shift control to manually
select a lower gear.
If equipped with Tow N Go, it is recommended
to place the vehicle in tow mode by pushing the
TOW button.
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.
AutoStick
When using the AutoStick shift control, select
the highest gear that allows for adequate perfor -
mance 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 necessary to avoid extended driving at
high RPM. Return to a higher gear or vehicle
speed when grade and road conditions allow.
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 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.

194SAFETY
Disabling And Enabling HSA
This feature can be turned on or turned off.
To change the current setting see Ú page 159.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When Rain
Brake Support is active, there is no notification to
the driver and no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Controller (EBC) will prepare the brake system for
a panic stop.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of
each of the driven wheels. If wheel spin is
detected, the TCS may apply brake pressure to the
spinning wheel(s) and/or reduce engine power to
provide enhanced acceleration and stability. A
feature of the TCS, Brake Limited Differential (BLD)
functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one
wheel on a driven axle is spinning faster than the
other, the system will apply the brake of the
spinning wheel. This will allow more engine power
to be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and ESC are
in reduced modes.
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation 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. Failure to
follow these warnings can result in a collision or
serious personal injury.
WARNING!
If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there
may not be enough brake pressure to hold
both the vehicle and the trailer on a hill when
the brake pedal is released. In order to avoid
rolling down an incline while resuming accel -
eration, manually activate the trailer brake or
apply more vehicle brake pressure prior to
releasing the brake pedal.
HSA is not a parking brake. Always apply the
parking brake fully when exiting your vehicle.
Also, be certain to place the transmission
in PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

21_WD_OM_EN_USC_t.book Page 194

SAFETY195
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the
appropriate actions to attempt to stop the sway.
Note that TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and follow
the trailer tongue weight recommendations
Úpage 142.

When TSC is functioning, the ESC Activation/
Malfunction Indicator Light will flash, the engine
power may be reduced and you may feel the brakes
being applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” mode.

AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
BSM uses two radar sensors, located inside the
rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.) that enter the blind spot zones from the rear/front/
side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light
will momentarily illuminate in both outside
rearview mirrors to let the driver know that the
system is operational. The BSM system sensors
operate when the vehicle is in any forward gear.
The BSM detection zone covers approximately one
lane in width, on both sides of the vehicle 12 ft
(3.8 m). The zone length starts at the side of the
vehicle, near the B-pillar, and extends
approximately 10 ft (3 m) beyond the rear fascia/
bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle
when the vehicle speed has reached
approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
The BSM system DOES NOT alert the driver
about rapidly approaching vehicles that are
outside the detection zones.
The BSM system detection zone DOES NOT
change if your vehicle is towing a trailer. There -
fore, visually verify the adjacent lane is clear for
both your vehicle and trailer before making a
lane change. If the trailer or other object (i.e.,
bicycle, sports equipment) extends beyond the
side of your vehicle, this may result in random
false detections on the trailer, and false chimes
when the turn signal is used Ú page 159.
The BSM system can become blocked if snow,
ice, mud, or other road contaminations accumu -
late on the rear fascia/bumper where the radar
sensors are located. The system may also
detect blockage if the vehicle is operated in
areas with extremely low radar returns such as
a desert or parallel to a large elevation drop. If
blockage is detected, a “Blind Spot Temporarily
Unavailable, Wipe Rear Corners” message will
display in the cluster, both mirror lights will illu -
minate, and BSM and RCP alerts will not occur.
This is normal operation. The system will auto -
matically recover and resume function when the
condition clears. To minimize system blockage,
do not block the area of the rear fascia/bumper
WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and
adjust the trailer load to eliminate trailer sway.
