STARTING AND OPERATING 271
To exit ERS mode, simply push and hold the GEAR+ switch
until the gear limit display disappears from the instrument
cluster.
When to Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting occurs,
push the TOW/HAUL switch to activate TOW/HAUL
mode. This will improve performance and reduce the poten-
tial for transmission overheating or failure due to excessive
shifting. TOW/HAUL Switch
The “TOW/HAUL Indicator Light” will illuminate in the
instrument cluster to indicate that TOW/HAUL mode has
been activated. Pushing the switch a second time restores
normal operation. Normal operation is always the default at
engine start-up. If TOW/HAUL mode is desired, the switch
must be pushed each time the engine is started.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

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

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.
