When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying a
heavy load, etc., and frequent transmission shifting
occurs, push the TOW/HAUL switch to activate TOW/
HAUL mode. This will improve performance and reduce
the potential for transmission overheating or failure due
to excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the
transmission will automatically downshift (for engine
braking) when the throttle is closed and/or during
steady braking maneuvers.
The TOW/HAUL Indicator Light will illuminate in the
instrument cluster to indicate that TOW/HAUL mode
has been activated. Pushing the switch a second time
restores normal operation. Normal operation is always
the default at engine start-up. If TOW/HAUL mode is
desired, the switch must be pushed each time the
engine is started.
WARNING!
Do not use the TOW/HAUL feature when driving in icy
or slippery conditions. The increased engine braking
can cause the rear wheels to slide, and the vehicle to
swing around with the possible loss of vehicle control,
which may cause an accident possibly resulting in
personal injury or death.
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 accel-
erations, 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 transmission is not shifting properly when cold;
this is normal. Using the Electronic Range Select
(ERS) shift control, when the transmission is suffi-
ciently 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 transmis-
sion. The torque converter will refill within five sec-
onds 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 Power
Take Off (PTO). If 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 Builder’s Guide by

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.
