4WD DODGE RAM 2500 DIESEL 2009 4.G User Guide

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 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.
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 - Locks the front and rear
driveshafts together forcing the front and rear wheels to
rotate at the same speed. Additional traction and maxi-
mum pulling power for loose, slippery road surfaces
only. Do not exceed 25 mph (40 km/h).N
Neutral - This range disengages the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in this section.
Shifting Procedure — Electronically Shifted
Transfer CaseNOTE:•
If any of the requirements to select a new transfer case
position have not been met, the transfer case will not
shift. The “Transfer Case Position Indicator Light” for
the previous position will remain ON and the newly
selected “Transfer Case 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.
276 STARTING AND OPERATING

•
If all the requirements to select a new transfer case
position have been met, the current “Transfer Case
Position Indicator Light” will turn OFF, the selected
“Transfer Case Position Indicator Light” will flash
until the transfer case completes the shift. When the
shift is completed, the “Transfer Case Position Indica-
tor Light” for the selected position will stop flashing
and remain ON.
2WD⇔4WD LOCKRotate the transfer case switch to the desired position.
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 turn-
ing the switch. If the vehicle is stopped, the ignition key
must be in the ON position with the engine either
running or off. This shift cannot be completed if the key
is in the ACC position. NOTE:
The transfer case will not allow shifts between
2WD and 4WD LOCK if the front and/or rear wheels are
spinning (no traction). In this situation, the selected
“Transfer Case Position Indicator Light” will flash and
the original “Transfer Case Position Indicator Light” will
remain ON. At this time, reduce speed and stop spinning
the wheels to complete the shift.
2WD or 4WD LOCK⇔ 4WD LOWNOTE: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 engine running, slow the vehicle to 2 to 3 mph (3
to 5 km/h).

accelerator and apply as little throttle as possible. Be sure
to adapt your speed and driving to the prevailing road
conditions.
WARNING!
•
ESP (Electronic Stability Program) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions.
•
ESP cannot prevent accidents, including those
resulting from excessive speed in turns, driving on
slippery surfaces, or hydroplaning. Only a safe,
attentive, and skillful driver can prevent accidents.
•
The capabilities of an ESP-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.The ESP system has multiple operating modes depend-
ing on vehicle type: Two-Wheel Drive (2WD) or Four-
Wheel Drive (4WD). Four-wheel drive vehicles may be
equipped with either a four-mode position (2WD/4WD
LOCK/4WD LOW/Neutral) transfer case or a five-mode
position (2WD/4WD AUTO/4WD LOCK/4WD LOW/
Neutral) transfer case. If you have a four-wheel drive
vehicle, and want to determine which transfer case is on
your vehicle and how to operate it, refer to the “Four
Wheel Drive Operation” in this section.
All 2WD vehicles and 4WD vehicles in 2WD,
AUTO or 4HI Modes can choose the following ESP
operating modes:ESP On
This is the normal operating mode for ESP in 2WD/
AUTO/4HI Modes and in 2WD vehicles. Whenever the
vehicle is started, or the transfer case (if equipped) is
shifted from 4WD LO or Neutral, back to 4WD LOCK or

overcome, turn ESP back on by momentarily depressing
the ESP OFF switch. This may be done while the vehicle
is in motion.
WARNING!
In the “Partial Off” mode, the engine torque reduc-
tion and stability features are desensitized. There-
fore, the enhanced vehicle stability offered by ESP is
unavailable.All 4WD vehicles in Auto and 4HI Modes can also
choose the following ESP operating mode. This is
the only ESP operating mode in 4LO:Full Off
This mode is intended for off-road use when ESP stability
features could inhibit vehicle maneuverability due to trail
conditions. This mode is entered by depressing and
holding the ESP OFF switch for five seconds when thevehicle is stopped and the engine is running. After five
seconds, the “ESP/TCS Indicator Light” will illuminate
and the “ESP 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 “ESP OFF” message will display and the
audible chime will sound when the shift lever is placed
into 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, ESP 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 ESP system shuts off. ESP
is off at low vehicle speeds so that it will not interfere
with off-road driving but ESP function returns to provide

the stability feature at speeds above 40 mph (64 km/h).
The “ESP/TCS Indicator Light” will always be illumi-
nated when ESP is off. To turn ESP on again, momen-
tarily depress the ESP OFF switch. This will restore the
normal “ESP On” mode of operation.
“ESP Off” is the only operating mode for ESP 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 ESP system will be in this
mode.
WARNING!
With the ESP switched off, the enhanced vehicle
stability offered by ESP is unavailable. In an emer-
gency evasive maneuver, the ESP system will not
engage to assist in maintaining stability. “ESP Off”
mode is intended for off-highway or off-road use,
only.
ESP/BAS Warning Light and ESP/TCS Indicator
LightThe malfunction indicator for the ESP is combined with
the BAS indicator. The “ESP/BAS Warning Light” and
the “ESP/TCS Indicator Light” in the instrument cluster
both come on when the ignition switch is turned to the
ON position. They should both go out with the engine
running. If the “ESP/BAS Warning Light” comes on
continuously with the engine running, a malfunction has
been detected in either the ESP or BAS system, or both. 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.
NOTE:•
The “ESP Indicator Light” and the “ESP/BAS Warning
Light” come on momentarily each time the ignition
switch is turned ON.
