The sales of the 4S shop should have told you when you bought the car.
I came back to read the instructions myself.
I left my car to the old man, and now I ride a bike, hehe.
Not much to say, answering questions is the key.
That w key is used to prevent slipping. Just press it when running in the snow in winter.
In fact, the principle is to control the engine speed with a gearbox. Even if you step on the accelerator very hard, the car won't get up quickly, lest the tire spin and slip.
But I feel that this is mainly used at low speed, and it is unnecessary to start at high speed, and it takes a long time to consume oil.
When starting: put the gearbox into the D gear, press the W key, the green indicator will light up, and enter the anti-skid mode.
When turning off the engine: press the button again, the indicator light will go out and the vehicle will run normally.
Don't worry that the vehicle will run over it.
