Principles of Operation

The AWD system is active all the time and requires no input from the driver. The AWD system continuously monitors vehicle conditions and automatically applies torque to the front wheels when conditions or a drive mode selection commands it. During normal operation, torque is always applied to the rear drive axle. If wheel slip is detected the vehicle is under heavy acceleration or if the vehicle is in a handling event, the AWD system commands the transfer case actuator motor to apply torque to the ball ramp and clutch, and provides a request for the front axle disconnect actuator to engage to provide AWD torque distribution across all four wheels.

Drive Mode Control 

NOTE: Drive mode changes may not be available when the ignition is off or when the engine is not running.

The system delivers a driving experience through a suite of sophisticated electronic vehicle systems. These systems optimize steering, handling and powertrain response. This provides a single location to control the performance settings of multiple systems.

Drive Mode Control (if equipped) 

Changing the drive mode automatically changes the functionality of the following systems:

Drive mode selection is made through the drive mode switch. For center console mounted drive mode switch, the switch is integral to the ATCM. For column shift stalk mounted drive mode switch, the mode selection is made using the drive mode button underneath the information display.
