•The pedals cannotbe adjusted when the vehicle is in
REVERSE or when the Speed Control System is on. The
following messages will appear on vehicles equipped
with an instrument cluster display if the pedals are
attempted to be adjusted when the system is locked out:
“Adjustable Pedal Disabled — Cruise Control Engaged”
or “Adjustable Pedal Disabled — Vehicle In Reverse”.
NOTE:
• Always adjust the pedals to a position that allows full
pedal travel.
• Further small adjustments may be necessary to find the
best possible seat/pedal position.
• For vehicles equipped with Driver Memory Seat, you
can use your remote keyless entry key fob or the
memory switch on the driver ’s door trim panel to return
the adjustable pedals to pre-programmed positions. Re-
fer to “Driver Memory Seat” in “Getting To Know Your
Vehicle” for further information.
WARNING!
Do not adjust the pedals while the vehicle is moving.
You could lose control and have an accident. Always
adjust the pedals while the vehicle is parked.
CAUTION!
Do not place any article under the adjustable pedals or
impede its ability to move, as it may cause damage to
the pedal controls. Pedal travel may become limited if
movement is stopped by an obstruction in the adjust-
able pedal’s path.
MIRRORS
Inside Day/Night Mirror — If Equipped
The mirror head can be adjusted up, down, left, and right
for various drivers. The mirror should be adjusted to center

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any emissions tests
can be performed.
• If the MIL is flashing while the vehicle is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.

GETTING TO KNOW YOUR INSTRUMENT PANEL 159

•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.
• (ON/OFF) switch has been activated.
• Vehicles with automatic transmission must be in PARK
or DRIVE.

STARTING AND OPERATING 267

SPEED CONTROL
When engaged, the Speed Control takes over accelerator
operations at speeds greater than 25 mph (40 km/h).
The Speed Control buttons are located on the right side of
the steering wheel.NOTE:
In order to ensure proper operation, the Speed
Control System has been designed to shut down if multiple
speed control functions are operated at the same time. If
this occurs, the Speed Control System can be reactivated by
pushing the Speed Control ON/OFF button and resetting
the desired vehicle set speed.
To Activate
Push the ON/OFF button. The Cruise Indicator Light in
the instrument cluster display will illuminate. To turn the
system off, push the ON/OFF button a second time. The
Cruise Indicator Light will turn off. The system should be
turned off when not in use.
WARNING!
Leaving the Speed Control system on when not in use
is dangerous. You could accidentally set the system or
cause it to go faster than you want. You could lose
control and have an accident. Always leave the system
off when you are not using it.
