STARTING AND OPERATING 245
Torque Converter Clutch
A feature designed to improve fuel economy
has been included in the automatic
transmission on your vehicle. A clutch within the
torque converter engages automatically at
calibrated speeds. This may result in a slightly
different feeling or response during normal
operation in the upper gears. When the vehicle
speed drops or during some accelerations, the
clutch automatically disengages.
NOTE:
The torque converter clutch will not engage,
until the transmission fluid and engine
coolant are warm [usually after 1 to 3 miles
(2 to 5 km) of driving]. Because engine speed
is higher when the torque converter clutch is
not engaged, it may seem as if the transmis-
sion is not shifting properly when cold. This is
normal. Using the Electronic Range Select
(ERS) shift control, when the transmission is
sufficiently warm, will demonstrate that the
transmission is able to shift into and out of
Overdrive.
If the vehicle has not been driven for several
days, the first few seconds of operation after
shifting the transmission into gear may seem
sluggish. This is due to the fluid partially
draining from the torque converter into the
transmission. This condition is normal and
will not cause damage to the transmission.
The torque converter will refill within five
seconds after starting the engine.
AUXILIARY SWITCHES — IF EQUIPPED
There can be up to six 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 sixth 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
instrument cluster display. 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.com
and choosing the appropriate links.
ACTIVE NOISE CANCELLATION
Your vehicle is equipped with an Active Noise
Cancellation system that cannot be turned off.
This system is designed to address exhaust and
engine noise. The system relies on four
microphones embedded in the headliner, which
monitor exhaust and engine noise, and assists
an onboard frequency generator, which creates
counteracting sound waves in the audio
system’s speakers. This helps keep the vehicle
quiet at idle and during drive. The system is
deactivated when the windows are rolled down.
FOUR-WHEEL DRIVE OPERATION — IF
EQUIPPED
Four-wheel drive trucks are equipped with
either a manually shifted transfer case or an
electronically shifted transfer case. Refer to the
operating instructions for your transfer case,
located in this section for further information.
