2019 JEEP GRAND CHEROKEE LIMITED differential

Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, the TCS may
apply brake pressure to the spinning wheel(s) and/or
reduce engine power to provide enhanced acceleration and
stability. A feature of the TCS, 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 power to be applied to the wheel
that is not spinning. BLD may remain enabled even if TCS
and ESC are in a reduced mode.
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 apply-
ing the brake of the appropriate wheel(s) to assist in
counteracting the oversteer or understeer condition. En-
gine 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 position.
• 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
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
accelerator and apply as little throttle as possible. Be sure to
adapt your speed and driving to the prevailing road
conditions.

SAFETY 171

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the Quadra-
Trac II transfer case. The optional ELSD axle is fully
automatic and requires no driver input to operate. Under
normal driving conditions, the unit functions as a standard
axle, balancing torque evenly between left and right
wheels. With a traction difference between left and right
wheels, the coupling will sense a speed difference. As one
wheel begins to spin faster than the other, torque will
automatically transfer from the wheel that has less traction,
to the wheel that has traction. While the transfer case and
axle coupling differ in design, their operation is similar.
Follow the Quadra-Trac II transfer case shifting informa-
tion, preceding this section, for shifting this system.
QUADRA-LIFT — IF EQUIPPED
Description
The Quadra-Lift air suspension system provides full time
load leveling capability along with the benefit of vehicle
height adjustment by the push of a button. The vehicle will
automatically raise and lower the ride height to adapt to
the appropriate driving conditions. At higher speeds, thevehicle will lower to an aerodynamic ride height and when
operating in off-road modes, the vehicle will raise the ride
height accordingly. The buttons near the terrain switch in
the center console area can be used to set preferred ride
height to match the appropriate conditions.
