4WD Ram 2500 2011 User Guide

drive will be automatically engaged when the vehicle
senses a loss of traction. Because the front axle is en-
gaged, this mode will result in lower fuel economy than
the 2WD mode.
When additional traction is required, the transfer case
4WD LOCK and 4WD LOW positions can be used to lock
the front and rear driveshafts together 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” for spe-
cific 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 in-
creased tire wear and damage to the driveline compo-
nents.
NOTE:The transfer case NEUTRAL position is selected
by depressing the recessed button located on the lowerleft 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 Operating” for further information.
Transfer Case Position Indicator Lights
The Transfer Case Position Indicator Lights (4WD,
4LOW, and 4WD AUTO) are located on the instrument
cluster and indicate the current and desired transfer case
selection. When you select a different transfer case posi-
tion, the position 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.

STARTING AND OPERATING 335

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 con-
tinue to flash.
3. The transfer casewill notshift.
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 knob back to the current position, wait five
seconds, and retry selection. To find the shift require-
ments, refer to theShifting Procedurefor your transfer
case, located in this section of the owner’s manual.
The “SVC 4WD Warning Light” monitors the electronic
shift four-wheel drive system. If this light remains onafter engine start up or illuminates during driving, it
means that the four-wheel drive system is not function-
ing properly and that service is required.
WARNING!
Always engage the parking brake when powering
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.
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
336 STARTING AND OPERATING

AUTO or 4WD LOCK positions at a given road speed.
Take care not to overspeed the engine and do not exceed
25 mph (40 km/h).
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case.
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 if you leave the
vehicle unattended with the transfer case in the
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear driveshafts from
the powertrain and will allow the vehicle to move
regardless of the transmission position. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position, see the information below:
2WD
Rear-Wheel Drive High Range - This range is for normal
street and highway driving on dry hard surfaced roads.

STARTING AND OPERATING 337

4WD AUTO
Four-Wheel Drive Auto Range - This range sends power
to the rear wheels. The four–wheel drive system will be
automatically engaged when the vehicle senses a loss of
traction. Additional traction for varying road conditions.
4WD LOCK
Four-Wheel Drive Lock Range - This range locks the front
and rear driveshafts together forcing the front and rear
wheels to rotate at the same speed. Additional traction
for loose, slippery road surfaces only.
4WD LOW
Four-Wheel Drive Low Range - This range provides low
speed four-wheel drive. Locks the front and rear drive-
shafts together forcing the front and rear wheels to rotate
at the same speed. Additional traction and maximum
pulling power for loose, slippery road surfaces only. Do
not exceed 25 mph (40 km/h).N
Neutral - This range disengages both the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting and Operating” for further
information.
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 indicator light for the previous
position will remain ON, and the newly selected
position indicator light will continue to flash until all
the requirements for the selected position have been
met. To retry a shift: return the control knob back to the
original position, make certain all shift requirements
have been met, wait five seconds and try the shift
again.
338 STARTING AND OPERATING

•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 position will stop flashing and remain
ON.
2WD⇔4WD AUTO or 4WD LOCK
Rotate the 4WD Control Switch to the desired position.
Shifts between 2WD and 4WD AUTO 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 accelera-
tor pedal after turning the control switch. If the vehicle is
stopped, the ignition switch 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.
2WD or 4WD AUTO or 4WD LOCK⇔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.
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, rotate the transfer case control
switch to the desired position.
4. After the desired position indicator light is ON (not
flashing), shift the transmission back into gear.

EVIC Equipped Vehicles
HSA is a Customer Programmable Feature on a EVIC
equipped vehicle. If you wish to turn off the HSA feature,
refer to “Electronic Vehicle Information Center (EVIC)/
Customer Programmable Features” in “Understanding
Your Instrument Panel” for further information.
Electronic Stability Control (ESC) – If Equipped
The ESC system enhances directional control and stabil-
ity of the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer condition.
Engine power may also be reduced to help the vehicle
maintain the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not matchthe intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
•Understeer - when the vehicle is turning less than
appropriate for the steering wheel position.
All Two-Wheel Drive Vehicles and Four-Wheel
Drive Vehicles in 2WD, 4WD AUTO, or 4WD
LOCK Modes Can Choose the Following ESP
Operating Modes:
ESC On
This is the normal operating mode for ESC in 2WD/4WD
AUTO/4WD LOCK modes and in 2WD vehicles. When-
ever the vehicle is started or the transfer case (if
equipped) is shifted from 4WD LOW or Neutral, back to
4WD LOCK or 4WD AUTO, the ESC system will be in
396 STARTING AND OPERATING

All Four-Wheel Drive Vehicles in 4WD AUTO and
4WD LOCK Modes Can Also Choose the
Following ESC Operating Mode. This is the Only
ESC Operating Mode in 4WD LOW:
Full Off
This mode is intended for off-road use when ESC stabil-
ity features could inhibit vehicle maneuverability due to
trail conditions. This mode is entered by pressing and
holding the “ESC Off” switch for five seconds when the
vehicle is stopped and the engine is running. After five
seconds, the “ESP Off Indicator Light” will illuminate
and the “ESC Off” message will appear in the odometer.
Press and release the trip odometer button located on the
instrument cluster to clear this message.
NOTE:The “ESC OFF” message will display and the
audible chime will sound when the shift lever is placedinto the PARK position from any other position and then
moved out of the PARK position. This will occur even if
the message was previously cleared.
In this mode, ESC and TCS except for the “limited slip”
feature described in the TCS section are turned off until
the vehicle reaches a speed of 40 mph (64 km/h). At
40 mph (64 km/h) the system returns to “Partial Off”
mode, described above. When the vehicle speed drops
below 35 mph (56 km/h) the ESC system shuts off. ESC
is off at low vehicle speeds so that it will not interfere
with off-road driving but ESC function returns to provide
the stability feature at speeds above 40 mph (64 km/h).
The “ESC Off Indicator Light” will always be illuminated
when ESC is off. To turn ESC on again, momentarily
press the “ESC Off” switch. This will restore the normal
“ESC On” mode of operation.
398 STARTING AND OPERATING

“ESC Off” is the only operating mode for ESC in 4WD
LOW. Whenever the vehicle is started in 4WD LOW or
the transfer case (if equipped) is shifted from 4WD LOCK
or NEUTRAL, to 4WD LOW, the ESC system will be in
this mode.
WARNING!
With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver the ESC system will not
engage to assist in maintaining stability. “ESC Off”
mode is intended for off-highway or off-road use
only.
ESC Activation/Malfunction Indicator Light and
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles (kilometers) at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/

transmission in gear (not in Neutral).
CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
NEUTRAL and the engine running. With the transfer
case in NEUTRAL, ensure that the engine is OFF
prior to shifting the transmission into PARK.
15. Remove the key fob from the ignition switch.
16. Attach the vehicle to the tow vehicle using a suitable
tow bar.
17. Release the parking brake.
NOTE:
•The transfer case cannot be shifted into NEUTRAL
from the 4WD AUTO (if equipped) position.
•Steps 1 through 5 are requirements that must be met
prior to pressing the NEUTRAL button, and must
continue to be met until the shift has been completed.
If any of these requirements are not met prior to
pressing the NEUTRAL button or are no longer met
during the shift, the NEUTRAL indicator light will
flash continuously until all requirements are met or
until the NEUTRAL button is released.
•The ignition switch must be in the ON/RUN position
for a shift to take place and for the position indicator
lights to be operable. If the ignition switch is not in the
ON/RUN position, the shift will not take place and no
position indicator lights will be on or flashing.
•A flashing NEUTRAL indicator light indicates that
shift requirements have not been met.
