What does pwr button of motor vehicle mean?

The pwr button of a motor vehicle is an indicator light that automatically changes the driving mode. When the mode selection switch is pressed, the indicator light will be displayed. PWR means that in power mode, the' ECT PWR' light on the instrument panel lights up, and the transmission shifts into a high gear when the vehicle speed is high, and shifts into a low gear more sensitively than in normal mode. PWR is the set value of the electronic throttle. After stepping on the accelerator, the accelerator will respond faster, delaying the timing of upshifting to peak torque, and even stepping on the accelerator deeply will even drop several gears. PWR is usually in normal mode. When the mode selection switch is pressed, that is, PWR mode is selected, the indicator light will be displayed. At this time, after the vehicle is started, the power ratio is lower than the normal mode. Press the indicator light of PWR/NORM mode selection switch again to turn it off. PWR means that in power mode, the' ECT PWR' light on the instrument panel lights up, and the transmission shifts into a high gear when the vehicle speed is high, and shifts into a low gear more sensitively than in normal mode. In power mode, it is obvious that the vehicle has sufficient power, because the shifting of the gearbox becomes more radical in pwr mode. In normal mode, the shift may start at 2000 rpm, and in pwr power mode, the shift will start at 3000 rpm. The shift delay of the gearbox keeps the engine at a high speed and makes the vehicle have better dynamic response. The electronic throttle control system is proportional to the throttle opening under all driving conditions, and the output power of the straw generator is always appropriate. The electronic throttle control system has three modes: normal mode, power mode and snow mode. Normal mode: Lexus suggests using normal mode to save fuel when driving normally. Power mode: used to strengthen acceleration and sports driving.
