RAM 1500 CLASSIC 2020 Owner's Manual page 181

Because four-wheel drive provides improved
traction, there is a tendency to exceed safe turning
and stopping speeds. Do not go faster than road
conditions permit.
WARNING!
You or others could be injured or killed if you

leave the vehicle unattended with the transfer
case in the NEUTRAL (N) position without first
fully engaging the parking brake. The transfer
case NEUTRAL (N) position disengages both
the front and rear drive shaft from the power-
train, and will allow the vehicle to roll, even if
the transmission is in PARK. The parking
brake should always be applied when the
driver is not in the vehicle.
The transmission may not engage PARK if the

vehicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and
verify that the transmission gear position indi-
cator solidly indicates PARK (P) without
blinking. Ensure that the vehicle is completely
stopped, and the PARK position is properly
indicated, before exiting the vehicle.
Shifting Procedure
NOTE:
If any of the requirements to select a new

transfer case position have not been met, the
transfer case will not shift. The position indi-
cator light for the previous position will remain
on and the newly selected position indicator
light will continue to flash until all the require-
ments for the selected position have been met.
If all the requirements to select a new transfer

case position have been met, the current position
indicator light will turn off, the selected position
indicator light will flash until the transfer case
completes the shift. When the shift is complete,
the position indicator light for the selected posi-
tion will stop flashing and remain on.
2WD TO 4WD LOCK
Push the desired position on the 4WD control
switch to shift the transfer case. Shifts between
2WD and 4WD LOCK can be done with the vehicle
stopped or in motion. With the vehicle in motion,
the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal
after selecting the desired position on the control
switch. If the vehicle is stopped, the ignition must
be in the ON position with the engine either
running or off. This shift cannot be completed if the
ignition switch is in the ACC position.
STARTING AND OPERATING
NOTE:
The four-wheel drive system will not allow shifts
between 2WD/4WD LOCK if the front and/or rear
wheels are spinning (no traction). In this situation,
the selected position indicator light will flash and
the original position indicator light will remain ON.
At this time, reduce speed and stop spinning the
wheels to complete the shift.
2WD OR 4WD LOCK TO 4WD LOW
NOTE:
When shifting into or out of 4WD LOW some gear

noise may be heard. This noise is normal and is
not detrimental to the vehicle or occupants.
When shifting into 4WD LOW press and hold the

button until the indicator light starts blinking.
Shifting can be performed with the vehicle rolling
2 to 3 mph (3 to 5 km/h) or completely stopped.
Use either of the following procedures:
Preferred Procedure
1. With the engine running, slow the vehicle to
2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, push the desired position on
the transfer case control switch.
4. After the desired position indicator light is ON
(not flashing), shift the transmission back into
gear.
