HOW TO USE SUPER CRUISE®

Super Cruise®† is a driver assistance technology that allows hands-free driving on compatible roads. While you’re using the feature, it helps prompt you to pay close attention to the road so you’re ready to take control.

Learn how to use Super Cruise on vehicles equipped with this feature. Super Cruise requires an active subscription.
USING SUPER CRUISE

To use Super Cruise, Adaptive Cruise Control† must be on.

1. Make sure Adaptive Cruise Control is enabled. You will see one of two icons: a white illuminated Adaptive Cruise Control or a green illuminated icon with the set speed limit. If you don’t see either of these, press the Adaptive Cruise Control button on your steering wheel.

2. Then, when Super Cruise detects you are on a compatible road and all other driving conditions necessary for the feature to function are met (e.g., lane markings visible, GPS available, no system faults), the Super Cruise symbol illuminates in white on the instrument cluster.

a. On some models, you will have to center your vehicle in the lane before seeing the Super Cruise symbol appear.

3. When it is safe to do so, press the Super Cruise button on the steering wheel to engage Super Cruise.

a. When all other driving conditions are met but your vehicle is not centered in your lane, the Super Cruise symbol will light up blue until your vehicle is centered in your lane.

4. When the symbol and the steering wheel light bar illuminate in green, you may remove your hands from the steering wheel. You should not remove your hands from the steering wheel unless the light bar is green, which lets you know Super Cruise is steering the vehicle.

5. If an Adaptive Cruise Control† speed was not previously set, Super Cruise will set your current speed as the cruise speed.

6. On some models, Super Cruise is turned on, it will activate the Enhanced Automatic Emergency Braking†, Forward Collision Alert†, Lane Change Alert with Side Blind Zone Alert† and Trailer Side Blind Zone Alert† features, even if you had previously turned them off. On these vehicles, when you turn Super Cruise off, these features will revert to the settings you had previously set for them. On other vehicles, your settings for these features will remain set, even if you turn your vehicle off and on again.

TURNING SUPER CRUISE OFF

To turn Super Cruise off, press the Super Cruise button again or firmly take control of steering and press your brake pedal.

You can also turn Super Cruise off by pressing the Adaptive Cruise Control† on/off or cancel button, or by pulling the Regen On Demand paddle toward you on an EV.

UNDERSTANDING THE STEERING WHEEL LIGHT INDICATORS

When Super Cruise is off, the light bar on your steering wheel will be off and the Super Cruise symbol on your Driver Information Center will also be off. You must steer the vehicle.

When Super Cruise is on, the steering wheel light bar and Super Cruise symbol will indicate the system status. The symbol looks like a steering wheel. Here is what the lights on the bar and symbol mean:

  • Solid Green Bar and Solid Green Symbol: Super Cruise is active and automatically steering your vehicle.
  • Flashing Green Bar and Solid Green Symbol (1st Alert): Super Cruise is active, but the system detects that you need to pay attention to the road.
  • Pulsing Blue Bar and Solid Blue Symbol: Super Cruise is active, but the system detects that you are manually steering. To engage Super Cruise, position your vehicle in the center of the lane and hold the steering wheel steady until you see the green indicators.
  • Flashing Red Bar, Solid Red Symbol and Beeps Sound (2nd Alert): You need to take steering control immediately. The system cannot operate properly under current conditions. Your vehicle will begin to coast until you take steering control. You will have to turn Super Cruise back on to use the system again.
  • Flashing Red Bar, Solid Red Symbol, Beeps Sound, and Voice Prompt (3rd Alert): You need to take steering control immediately. A voice prompt will tell you to take over steering control. If you do not take steering control, your vehicle will steer and brake gradually to a stop in its current lane.
    • If this occurs, an OnStar Emergency-Certified Advisor† will contact you to ensure that you are safe and are paying attention to the road. 
    • Super Cruise will not be available until you turn your vehicle off and ignition cycle your vehicle again.
LANE CHANGE ON DEMAND

Select compatible GMC models equipped with Super Cruise can steer to perform a single lane change under certain conditions†, if Lane Change On Demand capability is enabled in the vehicle’s Settings menu. Not all vehicles with Super Cruise can do this. Lane change functionality does not work while trailering.

Remember, you must continue to focus on the road and traffic at all times, including prior to and during the lane change maneuver.

To request a lane change while you’re using Super Cruise with Lane Change On Demand:

1. Verify the lane next to your vehicle is clear and conditions are safe to make a lane change.

2. When Super Cruise is engaged, move the turn signal in the direction of the lane you’d like to change to. You do not need to fully latch the turn signal to activate Lane Change On Demand. Your vehicle will keep your turn signal active while Super Cruise completes the lane change maneuver. 

3. Super Cruise will then begin searching for an acceptable opening in the lane, while giving other drivers enough time to see your turn signal. You’ll see a message in your Driver Information Center (DIC) letting you know Super Cruise is looking for an opening.

a. If Super Cruise does not detect a lane opening in a certain amount of time, you will see a “canceled” message in your DIC and Super Cruise will revert to maintaining your lane position.

5. When Super Cruise determines the lane is open, it will begin to enter the lane. You’ll see a DIC message that says, “Auto Lane Change: Changing Lanes.”

6. When Lane Change On Demand is finished changing lanes, you’ll see a message in your DIC that says the lane change is complete. If you fully latched the turn signal to begin Lane Change On Demand, you must unlatch it when the lane change is finished to turn off the turn signal.

Early in a Lane Change On Demand maneuver, you can cancel it by moving the turn signal stalk away from the direction of the lane change. When you do this, your vehicle will return to its original lane and the Super Cruise symbol will remain green. At any time during the maneuver, you can cancel Lane Change On Demand by manually steering. The Super Cruise symbol will turn blue when you do this and the maneuver will be canceled. Once your vehicle is centered in the lane, the Super Cruise symbol will transition back to green.

If Super Cruise detects you aren’t paying attention to the road, if it cannot detect lane lines or if it detects a vehicle entering the lane after you’ve started transitioning out of the previous lane, you will see a DIC message indicating Lane Change On Demand has been canceled. The Super Cruise symbol will then turn red and you will need to immediately retake control of the vehicle.

Important information about lane change availability:

  • Lane Change On Demand functionality is only available on Super Cruise-enabled divided roads.
  • Super Cruise lane change functionality is not available when a construction zone is detected.
  • Super Cruise lane change will be disabled when a trailer is detected and may be disabled when other accessories (e.g., bike rack, cargo tray, etc.) are detected.
AUTOMATIC LANE CHANGE

On GMC models equipped with Super Cruise, if the Automatic Lane Change capability is enabled in the vehicle’s Settings menu, Super Cruise may initiate a lane change under the following conditions:

  • The Super Cruise System may initiate a lane change to the left or right to pass a slower-moving vehicle ahead and a subsequent lane change to return to your original lane.
  • The Super Cruise System may initiate a lane change to the left or right when the current lane is ending ahead.
  • The system may initiate an Automatic Lane Change to the left or right when a slower-moving vehicle is detected in a lane that’s ending to provide space for a merging vehicle. 

A message appears on the DIC during the lane change to provide more information on the status of the lane change. To cancel a Super Cruise lane change, move the turn signal lever or manually take over the steering wheel at any time.

You can enable or disable lane changes by going to Settings > Vehicle Personalization > Super Cruise Lane Change.

Important information about Automatic Lane Change availability:  

  • Lane change functionality does not work while trailering. 
  • If a bike rack or other object on the rear of your vehicle obstructs the rear radar sensor, the performance of Lane Change On Demand may be inhibited.

Note: Automatic Lane Change and Lane Change On Demand functionality will be temporarily disabled and will not be available when Super Cruise detects construction or while trailering.
TRAILERING WITH SUPER CRUISE

If your vehicle is properly equipped, Super Cruise can recognize when you’re pulling a trailer and automatically adjust the gap to the next vehicle ahead for extra stopping distance. Lane change functionality is temporarily disabled and will not be available when you’re trailering with Super Cruise.

On some older GMC HUMMER EV models, this enhancement will be delivered via a Vehicle Software Update.†

Once the update completes downloading, you will be prompted with a pop-up notification on your infotainment screen. This will appear once you shift your vehicle back into Park after your next drive.

If you have questions about this upgrade, contact OnStar to speak to an Advisor.

For your security, please don’t include personal info such as phone number, address or credit card details.

Troubleshooting Super Cruise Issues

Q&As

Does the Super Cruise system turn my vehicle into an autonomous vehicle?

No. Super Cruise can’t drive the vehicle or replace your responsibility to be attentive and ready to take control at any time. Even when Super Cruise is engaged, you must remain attentive and act as a supervisor for the system. 

Are there any cameras or sensors I need to keep clean for Super Cruise to work?

Yes. There is a forward-facing camera and radar sensors on all sides of the vehicle that must be kept clean. Refer to your Owner’s Manual for the locations of these sensors. 

If there is an obstruction on the road, will Super Cruise steer around it?

No. Super Cruise cannot steer to avoid any objects (including vehicles, animals, pedestrians, bicyclists, potholes, debris, construction barriers or cones). It is not a crash avoidance system. It is designed to help you stay in a single lane and works with Adaptive Cruise Control† to help you keep distance between you and the vehicle ahead of you.
