What does the "Rock" mode on the Selec-Terrain system optimize for?

The "Rock" mode on the Selec-Terrain system is specifically designed to optimize off-road traction when driving over rocky surfaces. This mode enhances the vehicle's ability to maintain grip on uneven terrain, which is essential for navigating challenging off-road conditions. By adjusting throttle response, shifting patterns, and traction control settings, "Rock" mode allows the vehicle to effectively tackle obstacles such as boulders and loose rocks, providing better control and stability. This ensures that the tires maintain optimal contact with the ground, reducing the risk of wheel slip and improving overall performance on rugged landscapes.

In comparison to the other choices, modes aimed at fuel efficiency, high-speed stability, or wet road performance are focused on different driving conditions that do not apply to rock crawling or navigating rough terrains.
