How do I activate the heat pump in my Audi e-Tron for optimal energy efficiency?

I recently purchased an Audi e-Tron and want to make sure I am using the heat pump effectively to minimize energy consumption. Can you provide step-by-step instructions on how to activate the heat pump and any additional tips for maximizing its efficiency?

To activate the heat pump in your Audi e-Tron, navigate to the climate control settings and select the 'Heat Pump' option. This will help reduce energy consumption by utilizing the heat from the outside air to heat the cabin, instead of relying solely on battery power. Additionally, make sure to keep your vehicle plugged in while pre-heating or pre-cooling the interior to preserve battery life.
