2016 JEEP GRAND CHEROKEE differential

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
information, preceding this section, for shifting this sys-
tem.
SELEC-TERRAIN — IF EQUIPPED
Description
Selec-Terrain combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.

mode by normal use of the air suspension switches. Refer
to “Quadra-Lift – If Equipped” in “Starting And Operat-
ing” for further information.
When To Use 4WD LOW Range — If Equipped
When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme situa-
tions such as deep snow, mud, or sand where additional
low speed pulling power is needed. Vehicle speeds in
excess of 25 mph (40 km/h) should be avoided when in
4WD LOW range.
WARNING!
Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range
locks front and rear drivelines together and does not
allow for differential action between the front to rear

driveshafts. Driving in 4WD-LOW on pavement will
cause driveline binding; use only on wet or slippery
surfaces.
Driving Through Water
Although your vehicle is capable of driving through
water, there are a number of precautions that must be
considered before entering the water.
NOTE:Your vehicle is capable of water fording in up to
20 inches (51 cm) of water, while crossing small rivers or
streams. To maintain optimal performance of your vehi-
cle’s heating and ventilation system it is recommended to
switch the system into recirculation mode during water
fording.5
