speed refers to the speed limit reminder. The function of the car's speed is the speed indicator light, generally used in vehicles with speed limit settings. When the speed exceeds the set range, the speed light will flash. If this light is illuminated on the car dashboard, it indicates that the vehicle has exceeded the speed limit, and the driver should reduce the speed. More related information is as follows: Car speed limiter: The car speed limiter uses microcomputer program control to effectively control the maximum driving speed of the vehicle without affecting the original power of the car. The main categories of car speed limiters on the market are: mechanical throttle (cable throttle) speed limiters and electronic throttle speed limiters. Centering on the two themes of logistics transportation and car safety, the car speed limiter not only controls the safety risks caused by speeding violations but also complies with the relevant standards for car registration and annual inspection.

When I drive my Land Cruiser on long trips, the feature I on most is the 'Speed' function, which is actually the cruise control system. After setting the speed on the highway, it automatically maintains the speed without needing to constantly press the accelerator, making long-distance driving much easier. Models with cruise control buttons on the steering wheel can activate it with just a press, effortlessly maintaining a speed of 120 km/h. This feature is especially useful on desert roads or highways with light traffic, as it reduces driving fatigue. However, I immediately switch back to manual control in complex road conditions, as safety is always the top priority. Additionally, the new Land Cruiser also comes with an upgraded adaptive cruise control that can automatically adjust speed based on the vehicle ahead.

You're asking about the Speed in the Land Cruiser, that refers to the cruise control function. This system uses an electronic control unit to adjust the throttle opening, maintaining the vehicle at a set speed. It's particularly useful on flat highways - after turning on the switch, you just need to set the speed value without pressing the accelerator. I think this feature is especially suitable for driving across western Gobi deserts in the Land Cruiser, allowing continuous driving for seven or eight hours without fatigue. Note it's better not to use it in rainy weather as sudden intervention on wet roads may cause skidding. Also, some older Land Cruiser models require modifications to add this function.

As a Land Cruiser owner for ten years, I use the Speed function every day, which is the cruise control system. The operation is extremely simple: push the lever on the right side of the steering wheel up to activate, then press the SET button to lock the speed once you reach your desired velocity. It's particularly stable cruising at 80 km/h on national highways, completely freeing your right foot. Another benefit of this feature for the fuel-guzzling Land Cruiser is fuel efficiency, as maintaining a constant speed saves more fuel than frequent acceleration. However, I advise against using it in urban areas or mountainous roads, especially on continuous curves, as it can reduce control.

The full name of the Land Cruiser's Speed function is the Constant Speed Control System, which we in the auto repair shop often refer to as cruise control. The principle involves the vehicle's computer receiving speed signals and controlling the throttle opening via a servo motor. There's a button with a speed icon in the steering wheel control area that serves as the switch. I've found that 90% of the malfunctions are due to poor button contact or issues with the speed sensor, and cleaning the contacts yourself can usually resolve the problem. It's recommended to inspect the related wiring every 20,000 kilometers to prevent sudden failures during long-distance driving.

When purchasing the Land Cruiser, the salesperson emphasized this 'Speed' function, which is actually cruise control. After activating it on the highway, the vehicle can automatically maintain the set speed, making long-distance driving particularly effortless. I tested it and found that setting it at 100km/h saves about 5% more fuel compared to manual throttle control. New owners should note that the function can only be activated after fastening the seatbelt, and it automatically turns off in congested city traffic. Paired with the Land Cruiser's comfortable suspension, driving on the highway feels like riding a high-speed train.
