Brake and Accelerator Operation Techniques for Off-Road Driving For logs, walls, rocks, severe ditches, hills, sand, etc. 1. Bring the vehicle to a complete stop. Do not rev the engine. 2. Select the proper transmission and transfer case gear range; usually FIRST (1) gear, Four-Wheel-Low Lock for such obstacles. 3. If wheel spin is experienced, maintain steady throttle, with your foot off the brake pedal, to allow the Traction Control System (TCS) to control the wheel spin. TCS will not operate if the brakes are applied, even slightly. Your vehicle can climb a 16 inch (40.6 cm) vertical step. Step climbing is best done by approaching the step at an angle rather than straight on. 4. If wheel spin cannot be controlled by the system, fully press the brake pedal with your left foot so all wheel spin is halted. 5. Back away from the obstacle so that a new approach can be tried. 6. As the first wheel crosses the obstacle, be prepared to alternate the brake and accelerator pedal to maintain control and avoid tire drop-off from obstacles. Repeat this process for the other wheels. 4-22
