2014 JEEP WRANGLER brake

WARNING!(Continued)
•Failure to follow these warnings may cause the
vehicle to roll down the incline and could collide
with another vehicle, object or person, and cause
serious or fatal injury. Always remember to use the
parking brake while parking on a hill and that the
driver is responsible for braking the vehicle.
NOTE: The HSA system may also be turned on and off if
the vehicle is equipped with the Electronic Vehicle Infor-
mation Center (EVIC). Refer to “Electronic Vehicle Infor-
mation Center (EVIC)” in “Understanding Your Instru-
ment Panel” for further information.
HSA Off
If you wish to turn off the HSA system, follow this
procedure: 1. Start with the engine off and vehicle in PARK (auto-
matic transmission) or NEUTRAL with clutch out
(manual transmission) with wheels straight. Apply
parking brake on manual transmission vehicle.
2. Start the engine.
3. With the engine running, the brake applied, and the clutch out, rotate the steering wheel 180° counterclock-
wise from center.
4. Press the ESC OFF switch four times within twenty seconds.
5. Rotate the steering wheel 360° clockwise (180° clock- wise from center).
6. Cycle ignition switch OFF then ON.
7. If the sequence was completed properly, the “ESC Activation/Malfunction Indicator Light” will blink
several times to confirm HSA is off.
472 STARTING AND OPERATING

Steps 1-7 must be completed within 90 seconds to turn off
HSA. Repeat steps 1-7 to re-enable HSA functionality.
Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the
speed of the vehicle. When ERM determines that the rate
of change of the steering wheel angle and vehicle’s speed
are sufficient to potentially cause wheel lift, it applies the
appropriate brake and may reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers.
Electronic Roll Mitigation (ERM) can only reduce the
chance of wheel lift occurring during severe or evasive
driving maneuvers. It cannot prevent wheel lift due to
other factors such as road conditions, leaving the road-
way or striking objects or other vehicles.NOTE:
Anytime the ESC system is in the “Full Off”
mode, ERM is disabled. Refer to Electronic Stability
Control (ESC) for a complete explanation of the available
ESC modes.
WARNING!
Many factors, such as vehicle loading, road condi-
tions and driving conditions, influence the chance
that wheel lift or rollover may occur. Electronic Roll
Mitigation (ERM) cannot prevent all wheel lift or
rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the safety
of others.

Electronic Stability Control (ESC)
This system enhances directional control and stability of
the vehicle under various driving conditions. The ESC
corrects for over/under steering of the vehicle by apply-
ing the brake of the appropriate wheel to assist in
counteracting the over/under steer condition. Engine
power may also be reduced to help the vehicle maintain
the desired path.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the appro-
priate wheel to assist in counteracting the oversteer or
understeer condition.
•Oversteer - when the vehicle is turning more than
appropriate for the steering wheel position.
• Understeer - when the vehicle is turning less than
appropriate for the steering wheel position. The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster), starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also
flashes when TCS is active. If the “ESC Activation/
Malfunction Indicator Light” begins to flash during ac-
celeration, ease up on the accelerator and apply as little
throttle as possible. Be sure to adapt your speed and
driving to the prevailing road conditions.
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

474 STARTING AND OPERATING

In the ESC “Full Off” mode, the engine torque reduction
and stability features are disabled. Therefore, the en-
hanced vehicle stability offered by ESC is unavailable. In
an emergency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. “ESC Off” mode
is intended for off-highway or off-road use only.When in ESC Off mode, ESC and TCS, except for the
Brake Limited Differential (BLD) feature described in the
TCS section, are turned off until the vehicle reaches a
speed of 40 mph (64 km/h). For speeds at or exceeding
40 mph (64 km/h) the ESC goes into partial off. When the
vehicle speed drops below 35 mph (56 km/h), the ESC
system goes back to off. To turn ESC on again, momen-
tarily press the ESC OFF switch. This will restore normal
“ESC On” mode of operation. The
ESC Off Indicator
Light” will always be illuminated when ESC is off and
partial off.
WARNING!
With the ESC in Full Offmode, the engine torque
reduction and stability features offered by ESC and
ERM are disabled. In an emergency evasive maneu-
ver, 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 Brake
Limited Differential (BLD) feature described in the TCS
section, are turned off until the vehicle reaches a speed of
40 mph (64 km/h). For speeds at or exceeding 40 mph
(64 km/h) the ESC goes into partial 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 OFF 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.
WARNING!
In the ESC Full Offmode, the engine torque reduc-
tion and stability features are disabled. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. ESC Off
mode is intended for off-highway or off-road use
only.
478 STARTING AND OPERATING

NOTE:
•The “ESC Off Indicator Light” and the “ESC
Activation/Malfunction Indicator Light” come on mo-
mentarily each time the ignition switch is turned to the
ON/RUN position.
• Each time the ignition is cycled to the ON/RUN
position, the ESC system will be ON even if it was
cycled off previously.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
The “ESC OFF Indicator Light” indicates the
Electronic Stability Control (ESC) is partially
off or full off.Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an exces-
sively swaying trailer and will take the appropriate
actions to attempt to stop the sway. The system may
reduce engine power and apply the brake of the appro-
priate wheel(s) to counteract the sway of the trailer. TSC
will become active automatically once an excessively
swaying trailer is recognized. TSC cannot stop all trailers
from swaying. Always use caution when towing a trailer
and follow the tongue weight recommendations. Refer to
“Trailer Towing” in “Starting and Operating” for further
information. When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will flash, the
engine power may be reduced and you may feel the
brakes being applied to individual wheels to attempt to
stop the trailer from swaying. TSC is disabled when the
ESC system is in the “Partial Off” or “Full Off” modes.

STARTING AND OPERATING 481

WARNING!
If TSC activates while driving, slow the vehicle
down, stop at the nearest safe location, and adjust the
trailer load to eliminate trailer sway.
Hill Descent Control (HDC) — If Equipped
HDC is only intended for low speed off-road driving.
HDC maintains vehicle speed while descending hills in
off-road driving conditions by applying the brakes when
necessary.The symbol indicates the status of the Hill
Descent Control (HDC) feature. The lamp will
be on solid when HDC is armed. HDC can only
be armed when the transfer case is in the “4WD
LOW” position and the vehicle speed is less then 30 mph
(48 km/h). If these conditions are not met while attempt-
ing to use the HDC feature, the HDC indicator light will
flash on/off. When enabled, HDC senses the terrain and activates
when the vehicle is descending a hill. HDC speed may be
adjusted by the driver to suit the driving conditions. The
speed corresponds to the transmission gear selected.

482 STARTING AND OPERATING

However, the driver can override HDC operation by
applying the brake to slow the vehicle down below the
HDC control speed. If more speed is desired during HDC
control, the accelerator pedal will increase vehicle speed
in the usual manner. When either the brake or the
accelerator is released, HDC will control the vehicle at the
original set speed.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to“Four-Wheel Drive Operation” in “Starting and Oper-
ating” for further information.
2. Press the “Hill Descent” button. The “Hill Descent Control Indicator Light” in the instrument cluster will
turn on solid. NOTE:
•If the transfer case is not in 4WD LOW range, the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will not be enabled.
• If the ESC senses that the brakes are overheating the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.
Disabling HDC
Press the “Hill Descent” button or shift the transfer case
out of 4WD LOW range. The “Hill Descent Control
Indicator” light in the instrument cluster will turn off.
