What is Hummer EV Super Cruise?
Super Cruise – activated safely and correctly – allows you to temporarily remove your hands from the steering wheel and pedals on high-quality, multi-lane highways.
You must always be ready to jump back in and take control if the system fails or turns off. This could happen for multiple reasons, so it’s vital to always be aware and alert.
You must also adhere to local laws. For example, these might prevent removing your hands from the steering wheel at any time.
How to turn Super Cruise on in the Hummer EV
You need to be on a compatible road and meet many criteria to be able to use Super Cruise. See your owner’s manual for more information.
Follow the instructions below to turn on Super Cruise in your Hummer EV.
- Press the ACC button to turn on Advanced Cruise Control.
- You’ll find this on the left of your steering wheel.
- The white steering wheel icon displays in the instrument cluster when Super Cruise is available.
- Press the Super Cruise button.
- It’s a steering wheel in between lane markings.
- You’ll find this button next to the ACC control.
- Always check the white Super Cruise icon is on before pressing the button to avoid severe injury or death.
The ACC is now controlling the speed. It will either maintain the current speed or resume the previously-stored setting.
- When the steering wheel icon and light bar are blue, Super Cruise is not controlling the steering. You still have to do this yourself.
- Super Cruise controls the steering when the steering wheel icon and light bar are green.
You can manually override Super Cruise at any time by steering, accelerating, or braking. Read your owner’s manual for more information about how Super Cruise works (including the significant risks, automatic lane changes, and much more)!
Take Over Alert
Under any number of circumstances, the Hummer EV could instruct you to take control of the car immediately.
Find a more complete list of these situations in the owner’s manual.
If you don’t take control of the steering immediately, the Hummer EV will slow down and eventually stop in your lane. This in itself is incredibly dangerous but slightly less risky than continuing at highway speeds and crashing.
You’ll notice the following:
- Audible warning
- The steering wheel icon turns red
- The bar light turns red
- Display message appears in the instrument cluster
Resume steering immediately. Super Cruise will deactivate as soon as you grab the wheel.
Deactivating Hummer EV Super Cruise
There are two ways to deactivate Super Cruise on your Hummer EV.
- Press the Super Cruise button while your hands are on the steering wheel; or
- Tap the brake pedal.
- This disengages ACC as well as Super Cruise.
