Jeep Wrangler: Electronic Stability Control (ESC) / ESC Operating Modes
Depending upon model and mode of operation,
the ESC system may have multiple operating
modes.
ESC On
“ESC On” is the normal operating mode for the
ESC. Whenever the vehicle is started, the ESC
system will be in this mode. This mode should
be used for most driving conditions. Alternate
ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes
stuck. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed.
To enter the “Partial Off” mode, momentarily
push the ESC OFF switch and the ESC OFF
Indicator Light will illuminate. To turn the ESC
on again, momentarily push the ESC OFF switch
and the ESC OFF Indicator Light will turn off.
NOTE:
For vehicles with multiple partial ESC modes,
the push and release of the button will toggle
the ESC modes. Multiple attempts may be
required to return to “ESC On”.
WARNING!
- When in “Partial Off” mode, the TCS functionality
of ESC, except for the limited slip
feature described in the TCS section, has
been disabled and the ESC OFF Indicator
Light will be illuminated. When in “Partial
Off” mode, the engine power reduction
feature of TCS is disabled, and the
enhanced vehicle stability offered by the
ESC system is reduced.
- Trailer Sway Control (TSC) is disabled when
the ESC system is in the “Partial Off” mode.
ESC enhances directional control and stability
of the vehicle under various driving conditions.
ESC corrects for oversteering or understeering
of the vehicle by applying the brake of the
appropriate wheel(s) to counteract the above
conditions...
The “Full Off” mode is intended for off-highway
or off-road use only and should not be used on
any public roadways. In this mode, TCS and ESC
features are turned off...
Other information:
The Side Air Bags are designed to activate in
certain side impacts. The Occupant Restraint
Controller (ORC) determines whether the
deployment of the Side Air Bags in a particular
impact event is appropriate, based on the
severity and type of collision...
Do not interconnect the hydraulic brake
system or vacuum system of your vehicle
with that of the trailer. This could cause inadequate
braking and possible personal injury.
An electronically actuated trailer brake
controller is required when towing a trailer
with electronically actuated brakes...
