Selectable Drive Modes

The selectable drive mode system optimizes driveability and comfort as well as maximizing traction while operating on different types of terrain. Drive modes are selected using the AWDMSS and the ATCM controls the drive mode selection. When a drive mode is selected, the ATCM sends the drive mode message to the ABS module over the FD-CAN. When the ABS module receives the message, it alters the intervention thresholds for the stability and traction control features based on the selected mode. The ABS module also sends the drive mode message out to several other modules. The following modules receive the message and respond by altering their operation as follows:

• AWD module: automatically engages and disengages specific 4WD modes and raises or lowers torque output based on the selected mode.
• PCM : adjusts throttle response and gear changes to enhance powertrain response based on the selected mode.
• PSCM : adjusts steering effort and feel based on the selected mode.

The following drive modes are available:

• Baja 

  : For high speed off-road driving. Baja mode optimizes the throttle control for better response and torque delivery.

• Eco 

  : For efficient driving. This mode helps deliver maximum fuel efficiency and helps to increase driving range.

• Mud / Ruts 

  : For off-road driving. This mode enhances vehicle performance to traverse muddy, rutted or uneven terrains.

• Normal 

  : For everyday driving. This mode is a perfect balance of excitement, comfort and convenience. This is the default mode after each ignition cycle.

• Rock Crawl 

  : For off-road driving and optimum rock-climbing ability. Rock crawl mode optimizes the throttle and transmission response to provide additional control of the vehicle.

• Sand 

  : For off-road driving on soft, dry sand or deep snow.

• Slippery 

  : For less than ideal road conditions such as snow or ice covered roads. Slippery mode lowers throttle response and optimizes shifting for slippery surfaces.

• Sport 

  : For sporty driving with improved performance handling and response. This mode increases accelerator pedal response and provides a sportier steering feel. The powertrain system holds onto lower gears longer, allowing the vehicle to accelerate faster.

Drive mode changes are not available when the ignition is off. If a mode is unavailable, the system defaults to Normal mode.
