Four-wheel Drive
Active Drive (4WD) And Active Drive Low (4WD LOW)
Your vehicle may be equipped with a Power Transfer Unit (PTU). This system is automatic with no driver inputs or additional driving skills required. Under normal driving conditions, the front wheels provide most of the traction. If the front wheels begin to lose traction, power is shifted automatically to the rear wheels. The greater the front wheel traction loss, the greater the power transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle input (where one may have no wheel spin), torque will be sent to the rear in a preemptive effort to improve vehicle launch and performance characteristics.
CAUTION:
All wheels must have the same size and type tires. Unequal tire sizes must not be used. Unequal tire size may cause failure of the power transfer unit.
FOUR-WHEEL DRIVE (4WD)
The four-wheel drive (4WD) is fully automatic in normal driving mode.
Note:
It is not possible to carry out the change of mode when the vehicle exceeds the speed of 75 mph (120 km/h).
Enabling Four-Wheel Drive (4WD)
The buttons for the activation of four-wheel drive are located on the Selec-Terrain switch and allow you to select the following:
4WD LOCK
4WD LOW — (Trailhawk models only)
Active Drive Control — If Equipped
4WD LOCK Button
The Power Transfer Unit (PTU) is locked to ensure immediate availability of torque to the rear drive axles. This feature is selectable in AUTO mode and automatic in the other driving mode. 4WD LOCK can be enabled by the following ways:
When the 4WD LOCK button is pushed.
When the Selec-Terrain switch is rotated from AUTO to any other off-road modes.
Active Drive With Low Control — (Trailhawk Models Only)
4WD LOW Button (Trailhawk)
The 4WD LOW mode helps to improve the off-road performance in all modes. To enable 4WD LOW, please see the following steps:
Enabling 4WD LOW
With the vehicle stationary, the ignition in RUN position or with the engine running, shift the transmission into NEUTRAL and push the 4WD LOW button once. The instrument cluster will display the message "4WD LOW" once the shift is complete.
Note:
Both LOCK and LOW LED lights will blink and then become active on the Selec-Terrain switch until the shift is complete.
The instrument cluster display will illuminate the "4WD LOW" icon.
Disabling 4WD LOW
To disable the 4WD LOW mode, the vehicle must be stationary and the transmission shifted into NEUTRAL. Push the 4WD LOW button once.
