2019 RAM CHASSIS CAB brake light

352 STARTING AND OPERATING
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.
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 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 area.
Four-Pin Connector1 — Female Pins 4 — Park
2 — Male Pin 5 — Left Stop/Turn

STARTING AND OPERATING 361
3. Press and hold the brake pedal.
4. Shift the transfer case into NEUTRAL:
• With manual shift transfer case, shift the transfer case
lever into NEUTRAL (N).
• With electronic shift transfer case, push and hold the
transfer case NEUTRAL (N) button. Some models have
a small, recessed "N" button (at the center of the
transfer case switches) that must be pressed using a
ballpoint pen or similar object. Other models have a
rectangular NEUTRAL switch, below the rotary
transfer case control knob. The NEUTRAL (N) indi -
cator light will blink while the shift is in progress. The
light will stop blinking (stay on solid) when the shift to
NEUTRAL (N) is complete. After the shift is completed
and the NEUTRAL (N) light stays on, release the
NEUTRAL (N) button.
5. Release the parking brake.
6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds and ensure that
there is no vehicle movement.
8. Repeat steps six and seven with automatic transmission
in DRIVE. 9. 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.
10. Shift the transmission into PARK.
11. Place the ignition in the OFF mode, and remove the key
fob.
12. Attach the vehicle to the tow vehicle using a suitable tow
bar.
13. Release the parking brake.
NOTE:
With electronic shift transfer case:
• Steps 2 through 3 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. 5

362 STARTING AND OPERATING
• The ignition must be in the ON/RUN mode for a shift to
take place and for the position indicator lights to be oper -
able. If the ignition 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 indi -
cates that shift requirements have not been met.
Shifting Out Of NEUTRAL (N)
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop, leaving it connected
to the tow vehicle.
2. Firmly apply the parking brake.
3. Press and hold the brake pedal.
4. Start the engine, and shift the transmission into
NEUTRAL.
• 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) indicator light turns off,
release the NEUTRAL (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 indi -
cator 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 8-speed automatic transmission, the engine
must remain running, since turning the engine OFF will shift
the transmission to PARK (and the transmission must be in
NEUTRAL 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 auto -
matically select PARK when the engine is turned off.
6. Release the brake pedal.
7. Disconnect vehicle from the tow vehicle.
8. Start the engine.

STARTING AND OPERATING 363
9. Press and hold the brake pedal.
10. Release the parking brake.
11. Shift the transmission into gear, release the brake pedal,
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 oper -
able. If the ignition 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 indi -
cates that shift requirements have not been met. DRIVING TIPS
Driving On Slippery Surfaces
Acceleration
Rapid acceleration on snow covered, wet, or other slippery
surfaces may cause the driving wheels to pull erratically to
the right or left. This phenomenon occurs when there is a
difference in the surface traction under the rear (driving)
wheels.
WARNING!
Rapid acceleration on slippery surfaces is dangerous.
Unequal traction can cause sudden pulling of the rear
wheels. You could lose control of the vehicle and
possibly have a collision. Accelerate slowly and carefully
whenever there is likely to be poor traction (ice, snow,
wet, mud, loose sand, etc.). 5

364 STARTING AND OPERATING
Driving Through Water
Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and prevent
damage to your vehicle.
Flowing/Rising Water Shallow Standing Water
Although your vehicle is capable of driving through shallow
standing water, consider the following Cautions and Warn -
ings before doing so.
WARNING!
Do not drive on or across a road or path where water is
flowing and/or rising (as in storm run-off). Flowing
water can wear away the road or path's surface and cause
your vehicle to sink into deeper water. Furthermore,
flowing and/or rising water can carry your vehicle away
swiftly. Failure to follow this warning may result in
injuries that are serious or fatal to you, your passengers,
and others around you. WARNING!
• Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping
distances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake pedal
several times to dry the brakes.
• Failure to follow these warnings may result in injuries
that are serious or fatal to you, your passengers, and
others around you.
