4WD JEEP WRANGLER UNLIMITED 2011 Owners Manual

WARNING!
Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents, in-
cluding those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro-
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capa-
bilities of an ESC 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 ESC system has three available operating modes in
4H range. The system has one operating mode in 4L
range. Two-wheel drive vehicles and four-wheel drive
vehicles in 2H range have two operating modes.
4H Range (4WD Models) Or 2WD Models
On
This is the normal operating mode for ESC in 4H and
2WD vehicles.
Partial Off
This mode is entered by momentarily pressing the ESC
OFF switch.
426 STARTING AND OPERATING

WARNING!
With the ESC switched off, the enhanced vehicle
stability offered by ESC and ERM are unavailable. In
an emergency evasive maneuver, the ESC and ERM
systems will not engage to assist in maintaining
stability. The “Full Off” ESC mode is intended for
off-road use only.
4L Range (4WD Models)
ESC Off
This is the normal operating mode for ESC in 4L range.
Whenever the vehicle is started in 4L range, or the
transfer case (if equipped) is shifted from 4H range or
NEUTRAL to 4L range, the ESC system will be in this
mode. In 4L range, ESC and TCS, except for the “limitedslip” 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 ESC stability function
returns but TCS remains off. When the vehicle speed
drops below 35 mph (56 km/h), the ESC system shuts off.
The ESC is off at low vehicle speeds in 4L range so that it
will not interfere with off-road driving, but the ESC
function returns to provide the stability feature at speeds
above 40 mph (64 km/h). The “ESC Activation/
Malfunction Indicator Light” will always be illuminated
in 4L range when ESC is off.
NOTE:
The “ESC OFF” message will display and the
audible chime will sound when the shift lever is placed in
the PARK position from any position other than PARK,
and then moved out of the PARK position. This will
occur even if the message was previously cleared.
