2018 Ram 3500 brake light

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 isactivated 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 con-
nection 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
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 condi-
tion and should be changed as towing condi-
tions change. Changes to towing conditions
include trailer load, vehicle load, road condi-
tions 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 your trailer
dealer if necessary.

2. Hook up the trailer and make the electri-cal 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 recog-
nized 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” ap-
pears 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 maxi-
mum GAIN setting of 10.

the trailer brakes, driving and road state may
also affect the selection. Display Messages
The trailer brake control interacts with the
instrument cluster display. Display mes-
sages, along with a single chime, will be
displayed when a malfunction is determined
in the trailer connection, trailer brake con- trol, or on the trailer. Refer to “Instrument
Cluster Display” in “Getting To Know Your
Instrument Panel” for further information.
CAUTION!
Connecting a trailer that is not compatible
with the ITBM system may result in re-
STARTING AND OPERATING

The NEUTRAL (N) indicator light will
blink while the shift is in progress. The
light will stop blinking (stay on solid)
when the shift to NEUTRAL (N) is com-
plete. After the shift is completed and
the NEUTRAL (N) light stays on, re-
lease the NEUTRAL (N) button.
6. Release the parking brake.
7. Shift the transmission into REVERSE.
8. Release the brake pedal (and clutch pedal on manual transmissions) for five seconds
and ensure that there is no vehicle
movement.
9. Repeat steps 7 and 8 with automatic transmission in DRIVE or manual trans-
mission in first gear.
10. Shift the transmission to NEUTRAL. Firmly apply the parking brake. Turn OFF
the engine. For vehicles with Keyless
Enter-N-Go, push and hold the ENGINE
START/STOP button until the engine
shuts off.
11. Shift the transmission into PARK or place manual transmission in gear (NOT in Neutral). On 8-speed transmissions
the shifter will automatically select
PARK when the engine is turned off.
12. Turn the ignition to the OFF mode, then cycle the ignition to the RUN mode and
back to the OFF mode. Remove the key
fob from the ignition.
13. Attach the vehicle to the tow vehicle using a suitable tow bar.
14. Release the parking brake.
NOTE:
With electronic shift transfer case:
• Steps 2 through 4 are requirements that must be met before pushing the NEUTRAL
(N) button, and must continue to be met
until the shift has been completed. If any of
these requirements are not met before
pushing the NEUTRAL (N) button or are no
longer met during the shift, the NEUTRAL
(N) indicator light will flash continuously
until all requirements are met or until the
NEUTRAL (N) button is released. • The ignition must be in the ON/RUN mode
for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indicator
lights will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have
not been met.
• If the vehicle is equipped with air suspen- sion, the engine should be started and left
running for a minimum of 60 seconds (with
all the doors closed) at least once every
24 hours. This process allows the air sus-
pension to adjust the vehicle’s ride height
to compensate for temperature effects.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your
vehicle for normal usage:
1. Bring the vehicle to a complete stop, leav-
ing it connected to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
199

4. Start the engine. Shift the transmissioninto NEUTRAL. Depress the clutch pedal
on a manual transmission.
• With manual shift transfer case, shift the transfer case lever to the desired
position.
• With electronic shift transfer case with rotary selector switch, push and hold
the transfer case NEUTRAL (N) button
until the NEUTRAL (N) indicator light
turns off. After the NEUTRAL (N) indi-
cator light turns off, release the NEU-
TRAL (N) button. After the NEUTRAL
(N) button has been released, the
transfer case will shift to the position
indicated by the selector switch.
• With electronic shift transfer case with push-button selector switch, push and
hold the switch for the desired transfer
case position, until the NEUTRAL (N)
indicator light turns off and the desired
position indicator light turns on. NOTE:
When shifting out of transfer case NEUTRAL
(N), turning the engine OFF is not required,
but may be helpful to avoid gear clash. With
the 8-speed automatic transmission, the en-
gine must remain running, since turning the
engine OFF will shift the transmission to
PARK (and the transmission must be in NEU-
TRAL for the transfer case to shift out of
NEUTRAL).
5. Turn the engine OFF. Shift automatic
transmission into PARK. On 8-speed
transmissions the shifter will automati-
cally select PARK when the engine is
turned off.
6. Release the brake pedal (and clutch pedal on a manual transmission).
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal (and clutch pedal on
manual transmissions), and check that
the vehicle operates normally. NOTE:
With electronic shift transfer case:
• Steps 3 and 4 are requirements that must
be met before pushing the button to shift
out of NEUTRAL (N), and must continue to
be met until the shift has been completed.
If any of these requirements are not met
before pushing the button or are no longer
met during the shift, the NEUTRAL (N)
indicator light will flash continuously until
all requirements are met or until the button
is released.
• The ignition must be in the ON/RUN mode for a shift to take place and for the position
indicator lights to be operable. If the igni-
tion is not in the ON/RUN mode, the shift
will not take place and no position indicator
lights will be on or flashing.
• A flashing NEUTRAL (N) position indicator light indicates that shift requirements have
not been met.
