2009 Ram 1500 4WD

NOTE:To improve the vehicle’s traction when driving
with snow chains or starting off in deep snow, sand or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the ESP OFF switch. Once the situation
requiring ESP to be switched to the “Partial Off” mode is
overcome, turn ESP back on by momentarily pressing 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 Four-Wheel Drive Vehicles in 4WD AUTO and
4WD LOCK Modes Can Also Choose the
Following ESP Operating Mode. This is the Only
ESP Operating Mode in 4WD LOW:
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 pressing and holding
the ESP OFF switch for five seconds when the vehicle 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 instru-
ment 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 illuminated
when ESP is off. To turn ESP on again, momentarily
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 orthe 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
Light
The 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

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 depressing the transfer case NEUTRAL button
and must continue to be met until one second elapses
and the shift has been completed. If any of these
requirements (with the exception of step 3 - key ON)
are not met prior to pressing the NEUTRAL button, or
are no longer met during the one second time, then all
of the mode position indicator lights will flash con-
tinuously until all requirements are met or until the
NEUTRAL button is released.
•The ignition key must be ON for a transfer case shift to
take place and for the position indicator lights to be
operable. If the key is not ON, the shift will not take
place and no position indicator lights will be on or
flashing.
•The flashing NEUTRAL position indicator light indi-
cates that shift requirements have not been met.
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,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
