The Variable Torque Management
4WD System (VTM-4) automatically
transf ers varying amounts of engine
torque to the rear wheels under low
traction conditions.If more traction is needed when your
MDX is stuck or is likely to become
stuck, you can use the VTM-4 Lock
button to increase torque to the rear
wheels. As soon as this feature is no
longer needed, press the VTM-4
Lock button again to disengage the
VTM-4 Lock.
