[DeHarper]

You cannot start the car with one button if the key is not inside. The method to stop the engine with one-button start is as follows: 1. Press the brake pedal and bring the vehicle to a smooth stop; 2. Shift the gear from D to N; 3. Engage the handbrake; 4. Release the foot brake without turning off the power; 5. Press the foot brake again and shift the gear from N to P; 6. Release the foot brake and press the one-button start to turn off the power. The functions of one-button start include: 1. No need for the original car key or remote to unlock the door; 2. Automatic window closing when leaving the car; 3. Enhanced safety for night driving; 4. Convenient starting with self-diagnosis protection for the original starting system; 5. Built-in car anti-theft function.
