RAM 2015 1500, Operating Information Manual, Page: 274 / 998

This electronically shifted transfer case is de-
signed to be driven in the two-wheel drive
position (2WD) for normal street and highway
conditions on dry, hard surfaced roads.
When additional traction is required, the trans-
fer case 4WD LOCK 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 LOCK and 4WD LOW positions are
designed for loose, slippery road surfaces only.
Driving in the 4WD LOCK 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 position is se-
lected by pressing the button 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 Operat-
ing” 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 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 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.
NOTE:
Before retrying a selection, make certain
that all the necessary requirements for se-
lecting a new transfer case position have
been met. To retry the selection, turn the
control knob back to the current position,
wait five seconds, and retry selection. To
find the shift requirements, refer to the

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 illumi-
nates 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
Warning Light” is illuminated. Not engaging
the parking brake may allow the vehicle to
roll, which may cause personal injury.
