258 STARTING AND OPERATING

CAUTION!
If you skip a gear while downshifting or downshift
at too high of a vehicle speed, these conditions may
cause the engine to overspeed if too low of a gear is
selected and the clutch pedal is released. Damage to
the clutch and the transmission can result from
skipping a gear while downshifting or downshifting
at too high of a vehicle speed even if the clutch pedal
is held pressed (i.e., not released).
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.AUXILIARY SWITCHES — IF EQUIPPED
There can be up to five auxiliary switches located in the
lower switch bank of the instrument panel which can be
used to power various electronic devices and PTO
(Power Take Off) – If Equipped. If Power Take Off is
equipped, it will take the place of the fifth Auxiliary

switch. Connections to the switches are found under the
hood in the connectors attached to the auxiliary Power
Distribution Center.
You have the ability to configure the functionality of the
auxiliary switches via the Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID). All
switches can now be configured for setting the switch
type operation to latching or momentary, power source of
either battery or ignition, and ability to hold last state
across key cycles.
NOTE:Holding last state conditions are met when
switch type is set to latching and power source is set to
ignition.
For further information on using the auxiliary switches,
please refer to the Ram Body Builders Guide by accessing
www.rambodybuilder.comand choosing the appropri-
ate links.
POWER TAKE OFF OPERATION — IF EQUIPPED
(CHASSIS CAB ONLY)
This vehicle when equipped with PTO Prep and either
the AS69RC automatic six-speed or G-56 manual six-
speed transmissions, will allow for an aftermarket upfit
with a transmission 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. To select ’mobile
mode’ You will need to enter the commercial vehicle
menu on the EVIC/DID screen and select mobile PTO
mode. Details of the PTO selection modes and further
PTO information is available at the Ram Truck Body-
builders web site. www.rambodybuilder.com
AS69RC Six-Speed Automatic Transmission Only
The PTO drive gear (part of the AS69RC) operates at
torque converter turbine speed. The turbine speed will be
