What does ACC stand for in a car?

I’m teaching my son to drive and he noticed the second position on the ignition switch says ACC. He asked me what this stands for and I had to admit I don’t know. What does ACC stand for?

What a lucky kid! In this particular case, ACC stands for Accessory, which is the ignition position that turns on car accessories but not the engine.
When you turn your key to the second ignition position the engine does not turn. With your car in this position, you can use the following features and more without your engine running:
  • Windshield wipers
  • Radio
  • Power windows
  • Lights
  • Heat and air conditioning
Keep in mind that using a bunch of features without your car running could
drain the battery
. If you’re just listening to the radio you should be fine for a while.
But if you are blasting the heat your battery could drain rather quickly. To prevent this, turn your engine on for a couple of minutes every once in a while to charge the battery.
If you have a push-button start and want to access accessory mode, depending on your car model you may have to:
  • Press the start button once or twice without your foot on the brake
  • Shift into neutral, push the ignition button, then return the car to park
  • You may have an accessory button on your dashboard
However, ACC can also refer to
Adaptive Cruise Control
. Depending on the context, you’ll need to determine whether the reference is being made to the accessory ignition position or the driving feature.
If your son is going to be driving soon, this is a perfect time to make sure you have the best
