2004 JEEP GRAND CHEROKEE Cluster

Quadra-DriveTSystem Ð If Equipped
The optional Quadra-DrivetSystem features three
torque transfer couplings. The couplings include Vari-
Lok front and rear axles and Quadra-Trac IIttransfer
case. The optional Vari-Lok axles are fully automatic and
require no driver input to operate. Under normal driving
conditions the units function 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 automati-
cally transfer from the wheel that has less traction to the
wheel that has traction. While the transfer case and axle
couplings differ in design, their operation is similar.
Follow the Quadra-Trac IIttransfer case shifting infor-
mation, preceding this section, for shifting this system.
VARI-LOK FRONT AND REAR AXLES Ð IF
EQUIPPED
The optional Vari-Lok axle is fully automatic and requires
no driver input to operate. Under normal driving condi-
tions 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 automati-
cally transfer from the wheel that has less traction to the
wheel that has traction.
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 ªBrake Warning Lightº in the instru-
ment cluster will light.
194 STARTING AND OPERATING

NOTE:The instrument cluster ªBrake Warning Lightº
indicates only that the parking brake is applied. It does
not indicate the degree of brake application.Before leaving the vehicle parked on a hill, you must
make sure the parking brake is fully applied and place
the gear selector in the P (Park) position. Make certain the
transfer case is in gear. Failure to do so may cause the
vehicle to roll and cause damage or injury.
When parking on a hill, it is important to set the parking
brake before placing the gear selector in P (Park), other-
wise the load on the transmission locking mechanism
may make it difficult to move the selector out of P (Park).
The parking brake should always be applied when the
driver is not in the vehicle.
