What does S1 mean in automatic transmission?

[Dallas]

S1 is the sport mode. If you continue to accelerate, it will shift to S2, S3, and up to the highest gear. Normally, a car in D mode shifts at 3,000 RPM, but in S mode, it shifts at 5,000 RPM or higher. This mainly delays gear shifting to enhance the car's acceleration and achieve faster acceleration. The downside is increased fuel consumption and engine wear. Here is an introduction to the gears in an automatic transmission car: 1. P—Parking gear: Used when the car is parked and not in use. In this position, the wheels are mechanically locked to prevent rolling. 2. R—Reverse gear: Used for reversing. 3. N—Neutral gear: Used for temporary parking. Note that this gear indicates neutral. To prevent the car from rolling on a slope, always keep the brake pedal pressed. 4. D—Drive gear: Used for moving forward. 5. 2—Low gear: Used for starting on steep slopes or very inclined gradients. 6. L—Low gear: When going downhill or on long descents, placing the gear here limits the car to the lowest gear, allowing the engine to assist in braking. This prevents the driver from overusing the brakes, which could lead to overheating and potential danger.
