Continue cycling through for more information by continuing to press up and down arrow keys at same time.

Answer 16

– ABS also allows for Anti-Slip-Resistance (ASR) feature. If one wheel is off the road, spinning, ASR will apply that brake to increase torque to the other wheel, allowing it to pull the apparatus out. – If both wheels are spinning, ASR will reduce the engine torque to match the conditions. – ASR is completely automatic, the driver does not need to do anything.

Answer 17

Sometimes, you may not want the ASR to work at 100%, such as when trying to climb out of deep mud or snow, loose dirt or sand. – In that case, press the Off Road Traction Control switch. This will allow some slippage (spinning) to assist in climbing out. – Press again to turn off. It will also reset with the ignition switch cycling

Answer 18

* Onspot automatic chains are on the rear inside duals. * Effective up to about four inches. Advantage is ability to turn on for snowy or icy roads and off for clear roads. * Locking switch on the driver’s switch panel. – Engage when traveling between 2-25 mph just before reaching slippery conditions. – Do not exceed 35 mph. – Can stop on chains and start again, as long as switch is still in the active position.

Answer 19

– Comes on with master switch. – There is a momentary Opticom switch. – To operate: Press and hold the momentary button to turn on without master switch.
