Jeep Grand Cherokee 2015, Operating Information Manual, Page: 292 / 878

WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in off
road conditions. The driver must remain at-
tentive to the driving conditions and is re-
sponsible for maintaining a safe vehicle
speed.
Electronic Stability Control (ESC)
This system 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 to assist in
counteracting the oversteer or understeer con-
dition. 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
appropriate wheel to assist in counteracting the
oversteer or understeer condition.
•
Oversteer - when the vehicle is turning more
than appropriate for the steering wheel posi-
tion.
•
Understeer - when the vehicle is turning less
than appropriate for the steering wheel
position.
The “ESC Activation/Malfunction Indicator
Light” located 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
Activation/Malfunction Indicator Light” begins to
flash during acceleration, ease up on the accel-
erator and apply as little throttle as possible. Be
sure to adapt your speed and driving to the
prevailing road conditions.
WARNING!
The Electronic Stability Control (ESC) can-
not prevent the natural laws of physics from
acting on the vehicle, nor can it increase the
traction afforded by prevailing road condi-

tions. ESC cannot prevent collisions, includ-
ing those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent col-
lisions resulting from loss of vehicle control
due to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skillful
driver can prevent collisions. The capabilities
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.
ESC Operating Modes
Depending upon model and mode of operation,
the ESC system has up to three operating
modes: “ESC On” “Partial Off,” and “Full Off.”
ESC On — Two-Wheel Drive Vehicles And
Four-Wheel Drive Vehicles In 2WD And 4WD
High Range
This is the normal operating mode for ESC
when operating a two-wheel drive vehicle. It is
