Jeep Grand Cherokee Owner's Manual page 164

Full Off (4WD Models Only)
This mode is intended for off-highway or off-
road use when ESP stability features could
inhibit vehicle maneuverability due to trail con-
ditions. 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 Indi-
cator Light will illuminate, and the "ESP OFF"
message will appear in the Electronic Vehicle
Information Center (EVIC). Refer to "Electronic
Vehicle Information Center (EVIC)" in Section 4
of this manual for more information.
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 deactivated 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
162
turn ESP on again, momentarily press the ESP
OFF switch. This will restore the normal "ESP
On" mode of operation.
NOTE:
The "ESP OFF" message will display, and
the audible chime will sound, when the shift
lever is placed in 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.
WARNING!
With the ESP switched off, the enhanced
vehicle stability offered by ESP and ERM are
unavailable. In an emergency evasive maneu-
ver, the ESP and ERM systems will not en-
gage to assist in maintaining stability. The
"Full Off" ESP mode is intended for off-road
use only.
4WD Low Range
Full Off
This is the normal operating mode for ESP in
4WD LOW range. Whenever the vehicle is
started in 4WD LOW range, or the transfer case
(if equipped) is shifted from 4WD HIGH range
or NEUTRAL to 4WD LOW range, the ESP
system will be in this "Full Off" mode. In 4WD
LOW range, 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 normal ESP stability function
returns, but TCS remains off. When the vehicle
speed drops below 35 mph (56 km/h), the ESP
system shuts off. ESP is deactivated at low
vehicle speeds in 4WD LOW range so that it will
not interfere with off-road driving, but ESP func-
tion returns to provide the stability feature at
speeds above 40 mph (64 km/h). The ESP/TCS
Indicator Light will always be illuminated in
4WD LOW range when ESP is off.
