differential JEEP GRAND CHEROKEE 2005 WK / 3.G Owners Manual

“TRACTION SYS DISABLED” message will be displayed
in the Electronic Vehicle Information Center (EVIC).
Refer to Section 4 of this manual.
To turn the system back ON, press the switch a second
time, until the “Traction Control Indicator Light” turns
off.When the Traction Control System has been turned off
using the switch, a feature of the system remains active.
This feature functions similar to a limited slip differential
and controls the wheel spin across an axle. 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.
NOTE:
•The “Traction Control Indicator Light” comes on mo-
mentarily each time the ignition switch is turned ON.
This will occur even if you used the switch to turn the
system OFF.
•Each time the ignition is turned ON, the Traction
Control System will be ON even if it was turned OFF
previously.
•The Traction Control System will make buzzing or
clicking sounds when it is active.

To turn the ESP system OFF, press the switch, located
below the climate controls in the center stack, until the
ESP Indicator Lightin the instrument cluster turns on
and the messageESP SYSTEM DISABLEDappears in
the Electronic Vehicle Information Center (EVIC). Refer
to Section 4 of this manual. To turn the system back ON,
press the switch a second time until theESP Indicator
Lightturns off. ESP is always available during braking
(in 4WD Hi) even if it has been switched off.
When the ESP system has been switched off, a feature of

Quadra-DriveSystem — If Equipped
The optional Quadra-DriveSystem features three
torque transfer couplings. The couplings include ELSD
(Electronic Limited Slip Differential) front and rear axles
and Quadra-Trac IItransfer case. The optional ELSD
axles are fully automatic and require no driver input to
operate. Under normal driving conditions the units func-
tion as standard axles 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 couplings differ in design, theiroperation is similar. Follow the Quadra-Trac IItransfer
case shifting information, preceding this section, for
shifting this system.PARKING BRAKE
To set the parking brake, pull the lever up as firmly as
possible. When the parking brake is applied with the
ignition ON, the “Brake Warning Light” in the instru-
ment cluster will light.
NOTE:The instrument cluster “Brake Warning Light”
indicates only that the parking brake is applied. It does
not indicate the degree of brake application.
