2019 Ram 4500 Chassis Cab pedal

282 STARTING AND OPERATING
Stationary Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Transmission in PARK position.
• PTO switch has been activated.
• Brake pedal must not be applied.
• Vehicle engine must be running.
• No vehicle, or brake faults present.
• PTO must be correctly installed using the vehicle providedcircuits.
The instrument cluster will display a "PTO On" message for
five seconds if the above conditions are met. Otherwise, the
instrument cluster will display a message "To Operate PTO
Shift To Park" indicating what operator action should be
taken to engage the PTO mode.
The customer has the choice to operate the PTO by utilizing
the cruise control switches or by utilizing a remote control
(provided by the PTO supplier). To operate the feature using
the cruise control switches, the customer must first activate
the PTO switch which will turn on the PTO. In order to
increase or decrease the engine idle speed, to optimize the
PTO function, the “RESUME/ACCEL” and “DECEL” cruise switches can be used respectively. To disengage PTO opera
-
tion and return to “standard vehicle operation” simply
toggle the PTO switch to the OFF position.
The torque converter clutch (TCC) will automatically engage
at engine speeds above 1,200 RPM (engine speed) in PTO
stationary mode. Once engaged, the TCC will remain
applied and will not disengage until the engine speed falls
below 1,000 RPM. TCC engagement is desirable for certain
types of PTO applications (Automatic Transmission Only).
To operate the PTO via a remote switch, the customer must
make sure the above conditions are met. It is vital for proper
operation that the PTO and remote have been installed
correctly, paying special attention to ensure the vehicle
provided wiring has been connected properly. This is the
responsibility of the installer of the PTO and switches/
remote system. It is the responsibility of the PTO manufac -
turer to ensure that their electrical (switches and remote)
system is compatible with the vehicle’s electrical architecture
and software functionality.
NOTE:
Single set speed can be programmed via the PTO menu on
the instrument cluster display. Further details are available
at the Ram Truck Bodybuilders web site located at rambody-
builder.com

STARTING AND OPERATING 283
Mobile Mode
To operate the PTO in this mode the vehicle must meet the
following conditions:
• Mobile mode is activated via the menu on the instrumentcluster display.
• (ON/OFF) switch has been activated.
• Transmission must be in PARK or DRIVE.
• Parking brake must not be applied.
• Brake pedal must not be applied.
• No vehicle or brake faults present.
• Vehicle engine must be running.
• PTO must be correctly installed using the vehicle provided circuits.
The customer may choose to use the PTO while the vehicle is
moving. To do so, the PTO function must be activated prior
to taking the vehicle out of PARK. This is accomplished by
activating the upfitter-provided PTO on/off switch. At this
point, the customer may place the vehicle in a forward or
reverse gear and have PTO operation once the vehicle begins
to move. To disengage PTO operation and return to “stan -
dard vehicle operation” simply toggle the on/off switch to
the OFF position. NOTE:
For application specific information with respect to PTO and
pump requirements and additional vehicle information
(wiring schematics, preset idle values, engine speed limits,
and vehicle hardware and software requirements) please
refer to the Body Builders Guide by accessing

POWER STEERING
Hydraulic Power Steering
The standard power steering system will give you good
vehicle response and increased ease of maneuverability in
tight spaces. The system will provide mechanical steering
capability if power assist is lost.
If for some reason the power assist is interrupted, it will still
be possible to steer your vehicle. Under these conditions, you
will observe a substantial increase in steering effort, espe -
cially at very low vehicle speeds and during parking maneu-
vers.

STARTING AND OPERATING 287
U.S. Speed (mph)
• Pushing the SET (-) button once will result in a 1 mph decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 mph.
• If the button is continually pushed, the set speed will continue to decrease until the button is released, then the
new set speed will be established.
Metric Speed (km/h)
• Pushing the SET (-) button once will result in a 1 km/h decrease in set speed. Each subsequent tap of the button
results in a decrease of 1 km/h.
• If the button is continually pushed, the set speed will continue to decrease until the button is released, then the
new set speed will be established.
To Accelerate For Passing
Press the accelerator as you would normally. When the pedal
is released, the vehicle will return to the set speed. Using Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE:
The Speed Control system maintains speed up and down
hills. A slight speed change on moderate hills is normal.
On steep hills, a greater speed loss or gain may occur so it
may be preferable to drive without Speed Control.
WARNING!
Speed Control can be dangerous where the system
cannot maintain a constant speed. Your vehicle could go
too fast for the conditions, and you could lose control
and have an accident. Do not use Speed Control in heavy
traffic or on roads that are winding, icy, snow-covered or
slippery.

288 STARTING AND OPERATING
To Resume Speed
To resume a previously set speed, push the RES (+) button
and release. Resume can be used at any speed above 20 mph
(32 km/h).
To Deactivate
A soft tap on the brake pedal, pushing the CANCEL button,
or normal brake pressure while slowing the vehicle will
deactivate the Speed Control without erasing the set speed
from memory.
Pushing the On/Off button, or returning the ignition to OFF,
erases the set speed from memory.
ADAPTIVE CRUISE CONTROL (ACC) — IF EQUIPPED
Adaptive Cruise Control (ACC) increases the driving conve-
nience provided by cruise control while traveling on high -
ways and major roadways. However, it is not a safety system
and not designed to prevent collisions. Speed Control func-
tion performs differently. Please refer to the proper section
within this chapter.
ACC will allow you to keep cruise control engaged in light
to moderate traffic conditions without the constant need to
reset your cruise control. ACC utilizes a radar sensor and a forward facing camera designed to detect a vehicle directly
ahead of you.
NOTE:
• If the sensor does not detect a vehicle ahead of you, ACC
will maintain a fixed set speed.
• If the ACC sensor detects a vehicle ahead, ACC will apply limited braking or accelerate (not to exceed the original set
speed) automatically to maintain a preset following
distance, while matching the speed of the vehicle ahead.
The Cruise Control system has two control modes:
• Adaptive Cruise Control mode for maintaining an appro -
priate distance between vehicles.
• Normal (Fixed Speed) Cruise Control mode for cruising at a constant preset speed. For additional information, refer
to “Normal (Fixed Speed) Cruise Control Mode” in this
section.
NOTE:
Normal (Fixed Speed) Cruise Control will not react to
preceding vehicles. Always be aware of the mode selected.
You can change the mode by using the Cruise Control
buttons. The two control modes function differently. Always
confirm which mode is selected.

292 STARTING AND OPERATING
To Set A Desired ACC Speed
When the vehicle reaches the speed desired, push the SET (-)
button and release. The instrument cluster display will show
the set speed.
If the system is set when the vehicle speed is below 20 mph
(32 km/h), the set speed shall be defaulted to 20 mph
(32 km/h). If the system is set when the vehicle speed is
above 20 mph (32 km/h), the set speed shall be the current
speed of the vehicle.
NOTE:
ACC cannot be set if there is a stationary vehicle in front of
your vehicle in close proximity.
Remove your foot from the accelerator pedal, after the ACC
has been set. If you do not, the vehicle may continue to accel-
erate beyond the set speed. If this occurs:
• The message “ACC DRIVER OVERRIDE” will display in the instrument cluster display.
• The system will not be controlling the distance between your vehicle and the vehicle ahead. The vehicle speed will
only be determined by the position of the accelerator
pedal.
To Cancel
The following conditions cancel the system:
• The brake pedal is applied.
• The CANC (cancel) button is pushed.
• An Anti-Lock Brake System (ABS) event occurs.
• The gear selector is removed from the DRIVE position.
• The Electronic Stability Control/Traction Control System(ESC/TCS) activates.
• The vehicle parking brake is applied.
• Driver seatbelt is unbuckled at low speeds.
• Driver door is opened at low speeds.
• A Trailer Sway Control (TSC) event occurs.
• The driver switches ESC to full-off mode.
• The braking temperature exceeds normal range (over -
heated).

STARTING AND OPERATING 293
To Turn Off
The system will turn off and clear the set speed in memory if:
• The Adaptive Cruise Control (ACC) on/off button ispushed.
• The Normal (Fixed Speed) Cruise Control on/off button is pushed.
• The ignition is turned OFF.
• You switch to Four-Wheel Drive Low.
To Resume
If there is a set speed in memory push the RES (+) button and
then remove your foot from the accelerator pedal. The instru-
ment cluster display will display the last set speed.
NOTE:
• If your vehicle stays at standstill for longer than two seconds, the driver will have to push the RES (+) button to
reengage the ACC to the existing set speed.
• ACC cannot be resumed if there is a stationary vehicle in-front of your vehicle in close proximity.
To Vary The Speed Setting
To Increase Speed
While ACC is set, you can increase the set speed by pushing
the RES (+) button.
The speed increment shown is dependant on the chosen
speed unit of U.S. (mph) or Metric (km/h):
U.S. Speed (mph)
• Pushing the RES (+) button once will result in a 1 mph increase in set speed. Each subsequent tap of the button
results in an increase of 1 mph.
WARNING!
The Resume function should only be used if traffic and
road conditions permit. Resuming a set speed that is too
high or too low for prevailing traffic and road conditions
could cause the vehicle to accelerate or decelerate too
sharply for safe operation. Failure to follow these
warnings can result in a collision and death or serious
personal injury.

STARTING AND OPERATING 295
• The ACC system decelerates the vehicle to a full stop whenfollowing a target vehicle. If an ACC host vehicle follows a
target vehicle to a standstill, after two seconds the driver
will either have to push the RES (+) button, or apply the
accelerator pedal to reengage the ACC to the existing set
speed.
• The ACC system maintains set speed when driving up hill and down hill. However, a slight speed change on
moderate hills is normal. In addition, downshifting may
occur while climbing uphill or descending downhill. This
is normal operation and necessary to maintain set speed.
When driving up hill and down hill, the ACC system will
cancel if the braking temperature exceeds normal range
(overheated).Setting The Following Distance In ACC
The specified following distance for ACC can be set by
varying the distance setting between four bars (longest),
three bars (long), two bars (medium) and one bar (short).
Using this distance setting and the vehicle speed, ACC calcu-
lates and sets the distance to the vehicle ahead. This distance
setting displays in the instrument cluster display.
Distance Setting 4 Bars (Longest)

PARKSENSE REAR PARK ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system provides visual and
audible indications of the distance between the rear fascia
and a detected obstacle when backing up, e.g. during a
parking maneuver. Refer to “ParkSense System Usage
Precautions” in this section for limitations of this system and
recommendations.
ParkSense will retain the last system state (enabled or
disabled) from the last ignition cycle when the ignition is
changed to the ON/RUN position.5
