ECO mode Ram 3500 Chassis Cab 2018 Service Manual

•Brake pedal must not be applied.
• Vehicle engine must be running.
• No vehicle, brake or clutch switch faults present.
• PTO must be correctly installed using the vehicle pro-
vided circuits.
The instrument cluster will display a PTO Onmessage 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 operation and return to “standard vehicle
operation” simply toggle the PTO switch to the OFF
position.
The torque converter clutch (TCC) will automatically en-
gage 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
manufacturer 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 rambodybuilder.com
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 instru-
ment cluster display.

STARTING AND OPERATING 265

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.
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 turning the ignition switch
OFF erases the set speed from memory.
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.

transmission is shifted into PARK or the ignition is
switched to the OFF position.
Whenever the Rear View Camera image is activated
through the Backup Camera button in theControls
menu, a display timer for the image is initiated. The image
will continue to be displayed until the display timer exceeds 10 seconds and the vehicle speed is above 8 mph
(13 km/h) or the touchscreen button
Xto disable display
of the Rear View Camera image is pressed.

3+H1 (about 1/3 the difference between H2 and H1
above normal ride height [H1]).
8. Use the instrument cluster or touch screen radio settings and switch off tire jack mode. Make sure the truck
returns to normal ride height. Preform a visual inspec-
tion of the trailer and weight distributing hitch to
confirm manufacturers’ recommendations have been
met.

NOTE:Before installation of a snowplow it is highly
recommended that the owner/installer obtain and follow
the recommendations contained within the current Body
Builders Guide. See your authorized dealer, installer or
snowplow manufacturer for this information. There are
unique electrical systems that must be connected to prop-
erly assure operator safety and prevent overloading ve-
hicle systems.
WARNING!
Attaching a snowplow to this vehicle could adversely
affect performance of the airbag system in a collision.
Do not expect that the airbag will perform as described
earlier in this manual.
CAUTION!
The “Lamp Out” indicator could illuminate if exterior
lamps are not properly installed.
Before Plowing
• Check the hydraulic system for leaks and proper fluid
level.
• Check the mounting bolts and nuts for proper tightness. •
Check the runners and cutting edge for excessive wear.
The cutting edge should be ¼ to ½ in (6 cm to 1.2 cm)
above ground in snow plowing position.
• Check that snowplow lighting is connected and func-
tioning properly.

For Information about snowplow applications visit
www.ramtrucks.com or refer to the current Body Builders
Guide.
1. The maximum number of occupants in the truck should not exceed two.
2. The total GVWR or the Front GAWR or the Rear GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of options or passengers, etc.
The loaded vehicle weight, including the snowplow sys-
tem, all aftermarket accessories, driver, passengers, op-
tions, and cargo, must not exceed either the Gross Vehicle
Weight (GVWR) or Gross Axle Weight (GAWR) ratings.
These weights are specified on the Safety Compliance
