trailer Ram 1500 2016 Manual PDF

•Trailer brakes are recommended for trailers over
1,000 lbs (454 kg) and required for trailers in excess of
1,653 lbs (750 kg).
Integrated Trailer Brake Module — If Equipped
Your vehicle may have an Integrated Trailer Brake Mod-
ule (ITBM) for Electric and Electric Over Hydraulic
(EOH) trailer brakes.
NOTE:This module has been designed and verified with
electric trailer brakes and new electric over hydraulic
systems. Some previous EOH systems may not be com-
patible with ITBM.
Integrated Trailer Brake Module (ITBM)
1 — GAIN Adjustment Button
2 — GAIN Adjustment Button
3 — Manual Brake Control Lever 702 STARTING AND OPERATING

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 orsliding 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 Integrated
Trailer Brake Module (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 condi-
tions include trailer load, vehicle load, road conditions
and weather.

STARTING AND OPERATING 703

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 ad-
justed. See your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connec-
tions according to the trailer manufacturer’s instruc-
tions.
3. When a trailer with electric/EOH brakes is plugged
in, the trailer connected message should appear in the
EVIC/DID (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 EVIC/DID 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 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 com-
pletely.
9. If the trailer wheels lockup (indicated by squealing
tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
704 STARTING AND OPERATING

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 Electronic
Vehicle Information Center (EVIC) or Driver InformationDisplay (DID). Display messages, along with a single
chime, will be displayed when a malfunction is deter-
mined in the trailer connection, trailer brake control, or
on the trailer. Refer to “Electronic Vehicle Information
Center” or “Driver Information Display” in “Under-
standing Your Instrument Panel” for further information.

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 a increase in stop-
ping distance or trailer instability which could result
in damage to your vehicle, trailer, or other property.
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 a increase in stop-
ping distance or trailer instability which could result
in personal injury.NOTE:
•An aftermarket controller may be available for use
with trailers with air or electric-over-hydraulic 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 your authorized dealer if
an aftermarket module is to be installed.
706 STARTING AND OPERATING

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 har-
ness and connector.
NOTE:Do not cut or splice wiring into the vehicles
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.

Towing Tips
Before setting out on a trip, practice turning, stopping
and backing the trailer up in an area away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent
shifting does occur while in DRIVE, select TOW/HAUL
mode or select a lower gear range (using the Electronic
Range Select (ERS) shift control).
NOTE:Using TOW/HAUL mode or selecting a lower
gear range (using the ERS shift control) 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.

When towing a loaded trailer up steep grades at low
speeds (20 mph [32 km/h] or below), holding your
vehicle in first gear (using the ERS shift control) can help
to avoid transmission overheating.
If you regularly tow a trailer for more than 45 minutes of
continuous operation, then change the automatic trans-
mission fluid and filter(s) as specified forpolice, taxi,
fleet, or frequent trailer towing.Refer to the “Mainte-
nance Schedule” for the proper maintenance intervals.
NOTE:Check the automatic transmission fluid level
before towing (6-speed automatic only).
Tow/Haul Mode
To reduce potential for automatic transmission overheat-
ing, activate TOW/HAUL mode when driving in hilly
areas, or select a lower gear range (using the Electronic
Range Select (ERS) shift control) on more severe grades.
Electronic Speed Control — If Equipped
•Do not use in hilly terrain or with heavy loads.
•When using the speed control, if you experience 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.
Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
City Driving
When stopped for short periods of time, shift the trans-
mission into NEUTRAL and increase engine idle speed.
Highway Driving
Reduce speed.

STARTING AND OPERATING 709

Air Conditioning
Turn off temporarily.
Air Suspension System
To aid in attaching/detaching the trailer from the vehicle,
the air suspension system can be used. Refer to “Air
Suspension System” in “Starting And Operating” for
further information.
NOTE:The vehicle must remain in the engine running
position while attaching a trailer for proper leveling of
the air suspension system.
SNOWPLOW
1500 Models Only
NOTE:Do not use this model vehicle for snowplow
applications.
WARNING!
Snowplows and other aftermarket equipment should
not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in
the front end structure. The airbags could deploy
unexpectedly or could fail to deploy during a colli-
sion resulting in serious injury or death.
CAUTION!
Using this vehicle for snowplow applications can
cause damage to the vehicle.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
