Reverse Shifting
To shift into REVERSE (R), bring the vehicle to a com-
plete stop. Press the clutch and pause briefly to allow the
gear train to stop rotating. Beginning from the NEUTRAL
(N) position, move the shift lever in one quick smooth
motion straight across and into the REVERSE (R) area
(the driver will feel a firm “click” as the shifter passes the
“knock-over”). Complete the shift by pulling the shift
lever into REVERSE (R).
The “knock-over” prevents the driver from accidentally
entering the REVERSE (R) shift area and warns the driver
that they are about to shift the transmission into RE-
VERSE (R). Due to this feature, a slow shift to REVERSE
(R) can be perceived as a high shift effort.
To shift out of REVERSE bring the vehicle to a complete
stop and press the clutch. Shifting out of REVERSE prior
to a complete stop may cause high shift effort.
POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with either the AS68RC
automatic six-speed or G-56 manual six-speed transmis-
sions, will allow for an aftermarket upfit with a transmis-
sion driven PTO (power take off). The customer will have
the ability to operate the PTO in either a “stationary” or
“mobile” mode. The vehicles will be factory set to the
“stationary” mode. In order to select the “mobile” mode
an authorized dealership is required to modify the vehi-
cle’s settings using their proprietary authorized dealer
service tool.
AS68RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS68RC) operates at
torque converter turbine speed. The turbine speed will be
less than engine speed when the torque converter clutch
is not engaged and will be same as engine speed when
the torque converter clutch is engaged.
78 STARTING AND OPERATING

Stationary Mode
To operate the PTO in this mode the vehicle must meet
the following conditions:
•Be in PARK position (vehicles equipped with auto-
matic transmission)
•Upfitter provider (on/off) switch has been activated
•Parking brake applied (vehicles equipped with
manual transmission)
•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
provided circuits
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 oper-
ate the feature using the cruise control switches, the
customer must first activate the upfitter-provided on/off
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 turn the upfitter-provided on/off switch to the
OFF position.
The torque converter lockup clutch will automatically
engage at engine speeds above 1,200 RPM (engine speed)
in PTO stationary mode. Once engaged, the lockup clutch
will remain on and not disengage until the engine speed
is below 1,000 RPM. Lockup clutch engagement is desir-
able for certain types of PTO applications (AS68RC
Six-Speed Automatic Transmission Only).

STARTING AND OPERATING 79

The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center
(EVIC)” in “Understanding Your Instrument Panel” for
system messages and warnings.NOTE:
The DEF pump will run for a period of time
after engine shutdown to purge the DEF system. This is
normal operation.
