Just turn it off? right!
I havn't found that switch yet. Here is some more Info.
Adding to the overall sense of control is a highly developed Bosch four-channel antilock braking/traction control system (ABS/TCS). In addition to providing optimum control on slippery surfaces, the ABS can detect and adjust its braking capabilities to rough off-road surfaces like gravel and potholes. The TCS also provides the ability to gain traction through a single wheel, if necessary. A second mode of the TCS system, "TC2," used in conjunction with the transfer case's selections, provides three additionaloperating modes: "4 HI Locked + TC2," "4 LO Locked + TC2" and "4 LO Locked + Rear Diff Locked + TC2." This provides distinct advantages in different driving conditions, such as loose sand or gravel in the desert or mud or slippery conditions.
The H2's ABS is uniquely designed to detect rough-road surfaces and respond accordingly in addition to providing normal on-road control on slick surfaces. The ABS has separate control logic schemes to discern and react to deformable surfaces and provide the best solution for braking. As a result, the driver is frequently not aware that the ABS system is engaged, just feeling the sensation of a smooth responsive stop. In a very loose gravel surface, the driver may recognize added pedal travel during the stop, when the system has determined that more braking force is the correct solution. The result is an approximate 50 percent increase in deceleration on this surface condition.
