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 stop-
ping distance or trailer instability which could result in
damage to your vehicle, trailer, or other property.
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 elec-
tronic 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 har-
ness 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 con-
nector. Refer to the following illustrations.
NOTE:
•
Disconnect the trailer wiring connector from the
vehicle (or any other device plugged into the vehi-
cle's electrical connectors) before launching a boat
into water.
•
Be sure to reconnect once clear from water area.
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 move-
ment when gear selector is moved to PARK.
Automatic Transmission
Select the DRIVE (D) range when towing. The transmis-
sion 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.
