VTM-4 System VTM-4 LOCK BUTTON Your vehicle is equipped with a variable torque management 4-wheel-drive system (VTM-4) that distributes engine torque to the appropriate drive axle depending on the available traction conditions. The system is completely automatic, always active, and does not require any driver interaction. If you become stuck, you can activate the VTM-4 by pressing the VTM-4 LOCK button while in first (1), second (2), or reverse (R) gear below 18 mph (30 km/h). This mode overrides the auto system to send maximum torque to the rear axle. This mode is only intended for intermittent use at low speed to free your vehicle if it becomes stuck or when you encounter a steep grade with one wheel on a slippery surface. Generally, you should first allow the auto mode to operate to adjust for the available traction conditions. To Engage the VTM-4 Lock: 1. The vehicle speed must be below 18 mph (30 km/h). 2. Move the shift lever to first (1), second (2), or reverse (R) gear. 3. Press the VTM-4 LOCK button. The indicator in the button comes on. To get unstuck, apply light pressure to the accelerator pedal. Do not spin the front tires for more than a few seconds. Because of the amount of torque applied to the rear tires, they should not spin. This is normal. If you are not able to move the vehicle, stop and reverse direction. Do not use the VTM-4 LOCK button on dry, paved roads. Driving on dry, paved roads with VTM-4 Lock ON may damage the rear dif f erential when making a turn. Strange noise and vibration can also result. 198
