When the headlights are turned on, the Grace electronic throttle will be turned off.

. Hello, this may be because your battery is low. I turn on the headlights and turn off the lights. Just go to the repair shop and change the battery. I hope my answer is helpful to you. Have a nice trip. Thank you! If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
