Dodge 2007 Ram Pickup 3500 - Manual (Page 354)

The ESP system has multiple operating modes depend-
ing on vehicle type – Two Wheel Drive (2WD) or Four
Wheel Drive (4WD). 4WD vehicles may be equipped
with either a four mode position (2WD/Neutral/4HI/
4LO) transfer case or a five mode position (2WD/Auto/
Neutral/4H/4LO) transfer case. If you have a 4WD
vehicle, refer to the Four Wheel Drive Operating Section
to determine which transfer case is on your vehicle and
how to operate it.
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 4LO or neutral back to 4HI or Auto, the ESP
system will be in this mode. This mode should be used
for almost all driving situations. ESP should only be
turned to “Partial Off” or “ESP Off” for specific reasons
as noted below.
This mode is entered by momentarily
depressing the “ESP Control Switch”.
When in “Partial Off” mode, the TCS
portion of ESP, except for the “limited
slip” feature described in the TCS sec-
tion, has been disabled and the “ESP/
TCS Indicator Light” will be illumi-
nated. All other features of ESP function normally, with
the exception of engine power reduction. Engine power
is not reduced in this mode. This mode is intended to be
used if the vehicle is in deep snow, sand or gravel
conditions and more wheel spin than ESP would nor-
mally allow is required to gain traction. To turn ESP on
again, momentarily depress the “ESP Control Switch”.
This will restore the normal “ESP On” mode of operation.
