2014 JEEP GRAND CHEROKEE wheel

When the parking brake is applied with the ignition
switch in the ON position, the “Brake Warning Light” in
the instrument cluster will illuminate.NOTE:
•
When the parking brake is applied and the transmis-
sion is placed in gear, the “Brake Warning Light” will
flash. If vehicle speed is detected, a chime will sound
to alert the driver. Fully release the parking brake
before attempting to move the vehicle.
•
This light only shows that the parking brake is applied.
It does not show the degree of brake application.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
Parking Brake
416 STARTING AND OPERATING

WARNING!(Continued)
•Always fully apply the parking brake when leav-
ing your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.
CAUTION!
If the “Brake Warning Light” remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Traction Control System (TCS), Brake
Assist System (BAS), Electronic Roll Mitigation (ERM),
and Electronic Stability Control (ESC). All five of these
systems work together to enhance vehicle stability and
control in various driving conditions.
Also, your vehicle is equipped with Trailer Sway Control
(TSC).
Anti-Lock Brake System (ABS)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
418 STARTING AND OPERATING

WARNING!
The ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded by prevailing road conditions. The
ABS cannot prevent collisions, including those result-
ing from excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. The capabilities of
an ABS-equipped vehicle must never be exploited in a
reckless or dangerous manner which could jeopardize
the user’s safety or the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each
of the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability.A feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited-slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if
ESC system is in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for further
information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very
5
STARTING AND OPERATING 419

quickly results in the best BAS assistance. To receive the
benefit of the system, you must applycontinuousbrak-
ing pressure during the stopping sequence (do not
“pump” the brakes). Do not reduce brake pedal pressure
unless braking is no longer desired. Once the brake pedal
is released, the BAS is deactivated.
WARNING!
• The BAS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road conditions.
• The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
•
The capabilities of a BAS-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 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 then
applies the appropriate brake and may also reduce
engine power to lessen the chance that wheel lift will
occur. ERM will only intervene during very severe or
evasive driving maneuvers.
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 roadway, or striking objects or
other vehicles.
420 STARTING AND OPERATING

WARNING!
Many factors, such as vehicle loading, road condi-
tions, and driving conditions, influence the chance
that wheel lift or rollover may occur. 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 reck-
less 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. ESC cor-
rects for oversteering or understeering of the vehicle
by applying the brake of the appropriate wheel to assist
in counteracting the oversteer or understeer 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 will start to flash as soon
as the tires lose traction and the ESC system becomes
active. The “ESC Activation/Malfunction Indicator
Light” also flashes when the TCS is active. If the “ESC

Partial Off
This mode is entered by momentarily pressing the “ESC
OFF” switch. When in “Partial Off” mode, the TCS
portion of ESC, except for the BLD feature described in
the TCS section, has been disabled and the “ESC Off
Indicator Light” will be illuminated. All other stability
features of ESC function normally. This mode is intended
to be used if the vehicle is in deep snow, sand, or gravel
conditions and more wheel spin than ESC would nor-
mally allow is required to gain traction. To turn ESC on
again, momentarily press the “ESC OFF” switch. This
will restore the normal “ESC On” mode of operation.NOTE:To improve the vehicle’s traction when driving
with snow chains, or starting off in deep snow, sand, or
gravel, it may be desirable to switch to the “Partial Off”
mode by pressing the “ESC OFF” switch. Once the

NOTE:TheESC OFF message will display and the
audible chime will sound when the shift lever is moved
into the PARK position from any position other than
PARK and then moved out of the PARK position. This
will occur when the message was previously cleared.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled. There-
fore, the enhanced 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.
NOTE: When the ESC is switched OFF, a feature of the
system remains active. This feature controls wheel spin
across an axle quite similarly to a limited slip differential. If one wheel on an axle is spinning faster than the other,
the system will apply the brake of the spinning wheel
and allow more engine torque to be applied to the wheel
that is not spinning. To improve the vehicle’s traction
when driving with tire chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to switch
to the “Partial Off” mode by momentarily pressing the
“ESC Off” switch.
WARNING!
With the ESC switched OFF, the enhanced vehicle
stability offered by ESC is unavailable. In an emer-
gency evasive maneuver, the ESC system will not
engage to assist in maintaining stability. The “Full
Off” ESC mode is intended for off-highway or off-
road only.

STARTING AND OPERATING 425

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. Note that TSC cannot stop
all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations. Refer to “Trailer Towing” in this sec-
tion 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” mode.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.
