RAM 1500 2020 Owner's Manual page 235

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 in
the center of the 4WD Control Switch and is
pushed by using a ballpoint pen or similar
object. 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 HIGH, 4LOW, and 4WD AUTO) 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:
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 the transfer case does not shift into the
desired position, one or more of the following
events may occur:
1. The indicator light for the current position
will remain ON.
2. The newly selected position indicator light
will continue to flash.
3. If the transfer case will not shift, there will
be a cluster message stating the 4WD shift
has canceled.
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, push the current position, wait
five seconds, and retry selection. To find the
STARTING AND OPERATING
shift requirements, refer to the "Shifting Proce-
dure" for your transfer case, located in this
section.
The "SVC 4WD Warning Light" monitors the
electronically shifted 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.
WARNING!
Always engage the parking brake when pow-
ering down the vehicle if the "SVC 4WD Warn-
ing Light" is illuminated. Not engaging the
parking brake may allow the vehicle to roll
which may cause personal injury or death.
NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. This could
cause damage to driveline components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that
of the 2WD, 4WD AUTO 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).
