Questions and Answers on Super Cruise

The Super Cruise™ system available on the 2018 Cadillac CT6 automatically steers the vehicle when driving on a limited-access freeway, allowing drivers the convenience of hands-free driving. The system uses a variety of advanced technology so customers may have a number of questions about the system, how it operates, and when it can be used. (Fig. 7) Here are answers to a few frequently asked questions on Super Cruise.

Is Super Cruise driving the vehicle?


No. Super Cruise does not perform all aspects of driving nor does it do everything a driver can do. Super Cruise allows the driver to drive hands-free when conditions allow the feature to be available; but the driver needs to pay close attention to the road at all times.


What is defined as a limited-access freeway?


Super Cruise can only be used on limited-access freeways, which generally only allow high-speed traffic, are separated from opposing traffic, and are accessible by entrance and exit ramps only.


Besides being on a limited-access freeway, are there any other limitations for using Super Cruise?


Super Cruise should never be used under difficult or uncertain driving conditions, including in construction zones, when lane markings are poor, when there is limited visibility, while in a tunnel, when towing a trailer, on a road shoulder or service drive, or in slippery or other adverse conditions, including rain, sleet, fog, ice or snow.


To use Super Cruise, verify that Adaptive Cruise Control is on, Teen Driver is not active, Forward Automatic Braking is set to Alert and Brake, and camera and radar sensors are not obstructed or damaged.


What happens if a driver tries to activate Super Cruise when not on a limited-access freeway?


Super Cruise will not activate and a Driver Information Center message will display.


How does Super Cruise know how fast to go?


Super Cruise will use the Adaptive Cruise Control set speed. If the Adaptive Cruise Control speed is not set when Super Cruise is activated, it will use the current speed as the set speed. Super Cruise also will slow down around sharp curves.


When should the driver manually take control of the vehicle?


The vehicle needs to be manually steered when changing lanes or to avoid a traffic condition ahead, such as traffic cones, a pothole, road debris, etc. — even when Super Cruise is engaged. The steering wheel light bar pulses blue when the driver is steering.


To allow Super Cruise to resume steering again, simply position the vehicle in the center of the lane, hold the steering wheel until the light bar turns green and then release the steering wheel when it is safe to do so. If the driver takes control of the steering wheel and presses the brake pedal, Super Cruise and Adaptive Cruise Control will disengage.


Will Super Cruise know when the vehicle is entering a construction zone?


No. Super Cruise does not detect construction zones; the driver should always take control of steering prior to entering and while driving through construction zones.


If there’s an obstruction on the freeway, will Super Cruise steer around it?


No. Super Cruise can’t steer to avoid any objects (including other vehicles, animals, pedestrians, bicyclists, potholes, debris, construction barriers or cones). It is not a crash avoidance system. It is designed to assist the driver to stay in a single lane and work to keep a set distance between the vehicle and a vehicle ahead.


How is Super Cruise disengaged?


To disengage Super Cruise, press the Super Cruise button on the steering wheel or press the brake pedal.


Is the camera on the steering column recording?


No. The camera is part of the Driver Attention system and estimates driver attention to the road ahead. The camera does not record or share pictures, audio, or video.


Wearing sunglasses, hats or other types of clothing that alter the shape of the head may interfere with camera performance, which could cause Super Cruise not to be available.


Does the driver have to pay attention if Super Cruise is engaged?


It is important to always remember that Super Cruise is a convenience system and cannot accurately detect all situations. Super Cruise cannot determine whether the driver is awake, impaired or properly focused on safe driving. Complete attention is always required while driving, even when using Super Cruise. The driver should always be prepared to take over steering or apply the brakes at any time.


Why does a Super Cruise message appear on the infotainment system display after using it for a few minutes?


If Super Cruise has been steering for several minutes, a chime may sound and a Super Cruise message may be displayed on the infotainment system screen. This is to help ensure the driver is paying attention to the road and that the Driver Attention Camera is working properly. Read the message when it is safe to do so and the message will be removed. If the Driver Attention Camera determines that the driver has not read the message, Super Cruise will alert you.


A bike rack was installed on the vehicle, and now Super Cruise will not activate. Is there a connection?


If, as a result of the bike rack or other type of accessory on the rear bumper triggering collision alerts, the feature is set to the Off or Alert setting, as opposed to Alert and Brake, Super Cruise will not engage. Super Cruise will only work if the Forward Automatic Braking system is set to Alert and Brake. If you have a bike rack or other detectable object on the back of the vehicle, turn off Rear Parking Assist. This will help stop the collision alerts triggered by the accessory without impacting Super Cruise operation.


Why isn’t my Super Cruise system working?


Verify the following conditions are met:

  • The vehicle is on a limited-access freeway.
  • Adaptive Cruise Control is on.
  • Lane markings are clearly visible. Do not use Super Cruise in poor weather conditions or when visibility is limited.
  • The steering wheel is adjusted, and the driver’s face is visible.
  • Teen Driver is not active.
  • The Wi-Fi hotspot is turned on.
  • Forward Automatic Braking is set to Alert and Brake. Go to Settings > Vehicle > Collision/Detection Systems > Forward Collision System.
  • The camera or radar sensors are not obstructed or damaged.
