Below, our experts at Leesburg Buick GMC answer layered and practical FAQs based on real owner feedback and the exceptional technologies that are shaping your drive.
What is the AutoSense Power Liftgate and how does it work?
The AutoSense Power Liftgate is a hands-free technology that allows you to open the liftgate simply by approaching the rear of the vehicle with your key fob in hand. As you come within 10 feet, then move closer to within about 3 feet, the liftgate will prepare to open, signaled by four quick beeps and flashing exterior lights. For safety, this feature operates only when the vehicle is in PARK, and it can be enabled in the center display’s Hands-Free Exterior Storage Access settings. If a trailer is attached, the AutoSense function is temporarily disabled for your security.
Why did my liftgate not open, even though I heard the vehicle beeping?
If you receive beeps and light flashes but the liftgate doesn’t open, you may have moved out of the authentication zone (within 3 feet of the rear) during the three-second alert period. To avoid unintentional activation, simply step away or press the liftgate button on your key fob to cancel. Also, ensure your key fob is not muted—remaining in the approach zone for over two minutes will require you to unlock the vehicle or press a key fob button to reactivate the liftgate.
Is there a way to reset or disable the AutoSense Liftgate if needed?
Absolutely. Press and hold the liftgate’s interior button for over five seconds to turn the feature off or on. In the center display, navigate to Vehicle Settings > Comfort and Convenience to conveniently toggle AutoSense functionality. If the power liftgate is disabled, remember to re-enable AutoSense separately.
What is the eTrunk™ and Power Hood, and how do I access it?
The eTrunk™ is a spacious, secure storage compartment unique to select electric GMC vehicles, accessible through a Power Hood. You can open or close the Power Hood using the designated button inside the vehicle, on your key fob, or—on some models—with a fascia-mounted exterior button. This extra storage is conveniently powered, includes hooks and accessory outlets, and can even stow the Infinity Roof Sky Panels in the GMC HUMMER EV. Manual access is possible in case of loss of electric power.
Can I use my myGMC mobile app to control the eTrunk™ or Power Hood?
While you cannot directly open or close the eTrunk™ or Power Hood via the mobile app, select models allow you to lock the eTrunk™ remotely. For complete access, use the in-vehicle controls, key fob, or exterior button.
What are EV Energy Transfer Outlets and why should I use them?
Energy Transfer Outlets are high-capacity outlets in GMC EVs that allow you to power tools and devices using your vehicle’s battery. The system offers multiple 120V (20-amp circuits) and a single 240V (30-amp) outlet, with a maximum total power draw of 7.2 kW. Outlets can be managed through the Power Station app in the center display, with timer and range reserve settings to protect your driving range and automatically disable power once a set battery percentage or time is reached.
How can I monitor and protect the battery when using these EV outlets?
You can set limits on the duration or minimum battery state-of-charge using the Power Station interface. We recommend setting a prudent Range Reserve and using the Timer feature for events such as camping or power outages. The vehicle also provides real-time feedback on power draw to help you avoid exceeding the system’s limits.
How do seat and steering wheel temperature controls work in my GMC?
Depending on your model, you could have Cooled, Ventilated, and Heated Seat features for the front and rear outboard seating positions, plus a Heated Steering Wheel. Activate these features via physical buttons or with automatic mode in the center display, which uses outside and cabin temperature to adjust comfort settings. Remote Start will precondition seats and steering wheel for comfort based on the weather.
Why aren’t my passenger seat functions activating automatically?
Automatic seat heating, cooling, and ventilation on the passenger side require the seat to be occupied. Rear seat features must be activated manually and are limited to outboard seating positions. If a desired function isn’t operating, ensure the feature is enabled in the center display’s Climate and Air Quality menu.
What is Hands-Free Start, and is it available on every GMC?
Hands-Free Start lets you start your vehicle by simply sitting in the driver’s seat with the key fob on your person and closing the door or pressing the brake. There is no need for a traditional Start/Stop button in select GMC EV models. The system automatically turns off after inactivity while in PARK, and you can manually end the session through the Vehicle Off icon in the center display.
What if my vehicle does not start automatically when I close the driver door?
If the hood is open or if the key fob has been left inside from a prior drive, Hands-Free Start won’t engage when you close the door. In such cases, simply press the brake pedal to initialize the vehicle.
How does the In-Vehicle Trailering System enhance towing experiences?
The In-Vehicle Trailering App combines digital checklists, trailer profiles (including maintenance reminders), tire pressure monitoring (with accessory sensors), and integrated camera views for easier hitching, checking trailer lights, and situational awareness. For boats, it provides ramp launch guides and tutorials. Newer SUVs offer route planning in Google Maps engineered specifically for your trailer’s dimensions, helping you navigate low bridges and tight routes safely.
Does the Trailering system alert me to potential theft?
Yes, enable the Trailer Theft alert in your profile. If the trailer’s wiring harness disconnects while the vehicle is parked, the alarm sounds, and owners with active OnStar® Safety & Security plans (and notification preferences set) can receive immediate alerts.
