RAM 2500 2020 Owner's Manual page 253

When additional traction is required, the
transfer case 4WD HIGH and 4WD LOW
positions can be used to maximize torque to the
front driveshaft, forcing the front and rear
wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control
Switch to the desired position.
Refer to "Shifting Procedure" in this section for
specific shifting instructions.
The 4WD HIGH and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD HIGH and 4WD LOW
positions on dry hard surfaced roads may cause
increased tire wear and damage to the driveline
components.
NOTE:
The transfer case NEUTRAL button is located on
the lower left hand corner of the 4WD Control
Switch. The transfer case NEUTRAL position is
to be used for recreational towing only. Refer to
"Recreational Towing" in "Starting And Oper-
ating" for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights
(4WD and 4LOW) are located in the instrument
cluster and indicate the current and desired
transfer case selection. When you select a
different transfer case position, the indicator
lights will do the following:
If All Of The Following Shift Conditions Are Met:
1. The current position indicator light will turn
OFF.
2. The selected position indicator light will
flash until the transfer case completes the
shift.
3. When the shift is complete, the indicator
light for the selected position will stop
flashing and remain ON.
If One Or More Of The Following Shift Conditions
Are Not Met:
1. The indicator light for the current position
will remain ON.
2. The newly selected position indicator light
will continue to flash.
3. The transfer case will not shift.
STARTING AND OPERATING
NOTE:
Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry
the selection, turn the control switch back to the
current position, wait five seconds, and retry
selection. To find the shift requirements, refer
to the "Shifting Procedure" for your transfer
case, located in this section.
The "SVC 4WD Warning Light" monitors the
electronic shift four-wheel drive system. If this
light remains on after engine start up or
illuminates during driving, it means that the
four-wheel drive system is not functioning
properly and that service is required.
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning, as this can
cause damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 2WD or 4WD HIGH positions at a given
road speed. Take care not to overspeed the
engine and do not exceed 25 mph (40 km/h).
