2023 GMC Hummer EV Information Displays 

The information screens in the 2023 GMC Hummer EV are an example of cutting-edge technology being used together to give drivers a full and complete experience. A huge 13.4-inch diagonal touchscreen screen is in the front. It’s the command center for a lot of different functions, like navigation, entertainment, and setting up the car. Along with this huge screen, there is a 12.3-inch digital instrument panel that can be customized and shows a lot of important data. This makes sure that drivers always have access to important information. These screens have clear graphics, easy-to-use controls, and smart features that work well with each other. For example, Super Cruise lets you drive without using your hands, and the UltraVision system lets you see what’s under the car. The 2023 GMC Hummer EV’s information displays basically change the way we think about technology inside of cars. They provide a beautiful, information-packed cockpit that improves both the driving experience and the car’s overall usefulness, setting a new standard in the electric vehicle market.

• Charging
  Important Information about Electric Vehicle Charging Charging an electric vehicle can stress a building’s electrical system more than a typical household appliance.
• Charge cord limits can vary from vehicle to vehicle, and increased charging rates can stress a building’s electrical system.
• Before plugging into any electrical outlet ,have a qualified electrician inspect and verify the electrical system (electrical outlet, wiring, junctions, and protection devices) for heavy-duty service at a 12 amp continuous load.
• Electrical outlets may wear out with normal usage or may be damaged over time, making them unsuitable for electric vehicle charging.
• Check the electrical outlet/plug while charging and discontinue use if the electrical outlet/plug is hot, then have the electrical outlet serviced by a qualified electrician.
• When outdoors, plug into an electrical outlet that is weatherproof while in use.
• Mount the charging cord to reduce strain on the electrical outlet/plug.
• Do not place the charge cord in a position where it is expected to be submerged iNWS alter.

Danger

Improper use of portable electric vehicle charge cords may cause a fire, electrical shock, or burns, and may result in damage to property, serious injury, or death.

• Do not use extension cords, multi-outlet power strips, splitters, grounding adapters, surge protectors, or similar devices.

Danger (Continued)

• Do not use an electrical outlet that is worn or damaged, or will not hold the plug firmly in place.
• Do not use an electrical outlet that isn’t properly grounded.
• Do not use an electrical outlet that is on a circuit with other electrical loads.

When the dialog closes, the charging information listed on the Charging screen is updated to reflect any changes made.

Charge Later

Instead of charging immediately to a desired Charge Level, you may choose to delay the charge to the vehicle and have it complete by your desired departure time. This may be a more economical choice and a more efficient use of energy when charging at home. To use this mode, touch the Charge Later tab from the Charging screen.

With Charge Later selected, the Charging screen displays:

Text explaining that your vehicle will delay the planned charge to be ready by the time specified.
Charge Complete by: The time at which the vehicle will reach the desired Charge Level.

. Charge Level: The percentage to which you would like the vehicle to charge.
. An estimate of the vehicle’s range upon completing the charging session.
. Cabin Pre-Conditioning: Allows the vehicle to heat or cool the cabin to your desired temperature using energy from the charger. This means energy from the battery is not used to condition the cabin, ensuring the vehicle gets the greatest range from the charging session. Cabin pre-conditioning happens at the end of the charge, and right before the departure time.

To set the time desired for the vehicle to complete charging, touch the time listed under Charge Complete By. This will display the Charge Complete By dialog.

The Charge Complete By dialog displays:

• A time selector that allows you to specify the hour, the minutes in 15-minute increments at which the vehicle will reach the desired Charge Level.
  An allows you to close the Charge Complete By dialog. Settings made here are automatically saved when the dialog is exited.
