What does the '3' in front of the Corolla gear shift mean?

For the automatic transmission Toyota Corolla, the gear positions are as follows: P is for parking, R for reverse, D for automatic mode, '3' is for mountain driving and limits the transmission to third gear at most, and L is for low gear, used when the vehicle is stuck. Below are specific details: 1. Driving tips: When waiting at a red light, whether to use N or D gear can be based on personal preference. Temporarily stopping and holding the brake in D gear does not harm the vehicle. The torque converter in the transmission is equipped with a reaction wheel with a one-way clutch, which amplifies the torque from the engine crankshaft and does not rotate at engine idle speed, only engaging when the engine speed increases. 2. Engine start: When starting the engine, the automatic transmission also imposes gear restrictions. This is an adjustment made to the transmission for safety reasons. The engine can only be started when the gear lever is in the P or N position.
I often drive a Toyota Corolla, and the '3' position in front of the gear shift is actually designed to keep your automatic transmission shifting only among the first three gears, without going up to the fourth or higher gears. This is particularly useful in specific situations, such as driving downhill in 3rd gear to use the engine's resistance for deceleration, reducing the burden on the brakes and avoiding overheating and wear; or when towing items or climbing steep slopes, engaging 3rd gear provides stronger torque and power control, making the car respond more quickly. Having driven for over ten years, I've noticed many beginners are unaware of this function, wasting this safety protection design. I recommend not abusing it in congested urban areas, as it may increase fuel consumption or transmission load, but learning to use it appropriately is definitely a small trick to enhance driving pleasure and safety.
As someone who enjoys delving into automotive details, the number 3 in front of the Corolla's gear lever serves to limit the automatic transmission's highest gear to third. When you shift the gear lever to position 3, the transmission is locked to operate in first, second, or third gear, and will not automatically shift to higher gears. This is particularly useful in scenarios where the engine requires high RPM, such as on winding mountain roads, where staying in third gear helps maintain vehicle stability and reduces the jolts from frequent gear shifts. Similarly, in congested traffic, using third gear prevents sudden acceleration caused by automatic upshifts, making the car easier to control. However, it's important to remember that prolonged use may slightly increase fuel consumption, so it's best to switch to this mode only when necessary and return to normal driving mode afterward.
