How can I activate the accessory mode in a Chevy Tahoe?

★ Top Answer

To activate the accessory mode in your Chevy Tahoe, begin with the engine off. Without stepping on the brake pedal, press the start-stop button to enable the vehicle's accessory mode. In this mode, all electronic accessories in your SUV will operate, but the engine will remain idle. It's advisable to not keep your vehicle in accessory mode for an extended period as it may deplete the battery. When the engine is off, the alternator is also not functioning, making the electrical system solely dependent on the battery's stored energy.
