What does Crawl Mode mean?

Crawl Mode refers to the low-speed cruise driving assistance system, also known as the foolproof off-road system. This system ensures that the vehicle will not cause wheel slippage or get stuck when the speed is too high. It can be understood that the vehicle can automatically control the engine's torque output, transmission system, and brakes, allowing the car to pass through rough terrain at a very slow speed. In Crawl Mode, the driver only needs to focus on steering and does not need to press the accelerator or brake. The vehicle can control itself and release torque based on feedback from the road conditions. By electronically distributing the braking force to all four wheels, it prevents the wheels from slipping or getting stuck. On the lower right side of the central console gear lever, there is a knob that can be used to switch between three different speeds.
I remember the first time I used crawl control was on a muddy road back in my hometown, right after it had rained. The wheels kept slipping. This feature is like giving the car an automatic throttle control—no need to press the brake or accelerator at all. The system automatically adjusts the power output based on tire traction, making the car move forward steadily like a caterpillar. It's especially useful for driving on sand, snow slopes, or particularly steep mountain roads, and you don’t even need to be too precise with the steering wheel. Last time I took a friend to the desert, his manual transmission car got stuck in the sand three times, while my car with crawl control didn’t get stuck once. The difference was so obvious.
Once I accidentally activated the crawl mode while driving a friend's car. At a red light, I noticed the car inching forward slowly and initially thought the brakes had failed. Later, I learned that this is a unique low-speed cruise function for off-road vehicles, operating similarly to handing throttle control to the vehicle's computer. The system uses ESP to monitor wheel speed differences; if it detects a wheel spinning freely, it automatically locks the differential and distributes torque to the wheels with traction. Regular cruise control only supports speeds as low as 30 km/h, whereas this mode enables ultra-low-speed driving at 5 km/h. Toyota calls it Crawl Control, while Land Rover refers to it as All-Terrain Progress Control, but the core purpose is to assist drivers in escaping difficult terrain.
When driving an automatic transmission car through a gravel beach, I rely on the crawl mode, completely releasing the accelerator pedal, with both hands only needing to control the direction. The car, with the cooperation of the low gear of the transmission and engine braking, continuously outputs stable traction like a gecko climbing a wall. Compared to traditional four-wheel drive that requires constant tapping of the brakes to prevent skidding, this feature causes much less tire wear. The most practical scenario is descending long steep slopes; once activated, there's no need to constantly press the brakes, avoiding overheating and failure of the brake pads. Last year on the 72 bends of the Sichuan-Tibet line, I saw several car teams slowly descending slopes with this function turned on.
