UTILITY
WARNING!
You or others could be injured if you leave the vehicle unattended with the transfer
case in the N (NEUTRAL) position without first fully engaging the parking brake.
The transfer case N (NEUTRAL) position disengages both the front and rear
driveshafts from the powertrain and will allow the vehicle to move, even if the
transmission is in PARK. The parking brake should always be applied when the
driver is not in the vehicle.
