How to Use Adaptive Cruise Control

1. Adaptive Cruise Control is a different kind of cruise control. Instead of keeping your vehicle at a set speed, it’s designed to help keep a set distance between you and the vehicle in front of you. 

a. That distance is called the “following gap.”

2. On newer vehicles, Adaptive Cruise Control uses your vehicle’s forward-looking camera and radar sensors to detect vehicles directly ahead of you. That’s how it can speed up and slow down your vehicle to maintain the following gap you select.

3. On older vehicles, Adaptive Cruise Control will use either just the camera or just a radar to detect vehicles ahead.

4. The feature will work the same either way. The only thing that changes is what sensors you might have to clean in case they get dirty.

1. Some newer vehicles are equipped with a feature that detects nearby speed limit signs and can adjust your set Adaptive Cruise Control speed to the newly detected speed limit. Your vehicle must have the available Traffic Sign Recognition feature to use this part of Adaptive Cruise Control.
   
2. When your vehicle detects a new speed limit sign, you’ll see a prompt to change your set Adaptive Cruise Control speed in your DIC. You can choose to accept or deny the suggested speed. Press Resume/+ to accept or Set/- to deny.
   
3. If you don’t do anything, your vehicle will automatically set your Adaptive Cruise Control speed to the detected speed limit.
   
4. You can set an offset to the detected speed limit in case you want your set Adaptive Cruise Control speed to be higher or lower than the detected speed limit. Use the Resume/+ or Set/- buttons to set the offset. Your vehicle will remember the offset when a new speed limit is detected.
5. This feature may not work properly if the feature’s camera is obscured or dirty.

You should read your Owner’s Manual to learn more about the limitations of the system.

• Tap the brake pedal
• Press the Cancel button
• Press the cruise control On/Off button

2. Your vehicle must have the available Traffic Sign Recognition feature to use this part of Adaptive Cruise Control.

• You have to enable this in the Settings menu under "Collision and Detection." > "Adaptive Cruise Speed from Signs."

3. When you turn this on, Adaptive Cruise Control will automatically update its set speed when your vehicle detects a new speed limit sign.

4. If you don’t do anything, your vehicle will automatically set your Adaptive Cruise Control speed to the detected speed limit.

6. This feature may not work properly if the feature’s camera is obscured or dirty. Check your Owner’s Manual for more information on cleaning the camera.

On some newer vehicles, you can set an Adaptive Cruise Control speed while you’re stopped (the system must be on, you must apply the brake pedal and your vehicle must be in a Forward gear).

1. When your vehicle is stopped, hold the brake pedal and press the Set button.
2. Keep your foot on the brake and press the Resume/+ or Set/- buttons to set the cruise speed you want.
3. Then, lift your foot off the brake. The vehicle won’t move till you press the Resume button or press the accelerator.
4. Then, your vehicle will automatically accelerate to the set speed or following gap time if it detects a vehicle ahead.

On most vehicles, Adaptive Cruise Control can follow a vehicle ahead to a stop. When the vehicle ahead starts moving again, you should check that it’s safe to proceed and then either press the accelerator pedal or Resume/+ button to continue driving. For very brief stops, Adaptive Cruise Control will automatically resume and follow the vehicle ahead.

Adaptive Cruise Control has limited braking capability, so if the vehicle you’re following stops too suddenly, you’ll get an alert to take action by quickly applying the brakes yourself.

If your vehicle has the Driver Attention System on the steering column, Adaptive Cruise Control may automatically resume and follow the vehicle ahead for longer stops, if the system detects that you're paying attention to the road.

Check your Owner’s Manual to learn more about how Adaptive Cruise Control works on your vehicle at low speeds.

If equipped, you can also use Adaptive Cruise Control when towing an attached trailer that is electrically connected and within GM-approved allowable size and weight limits.

• When you have your trailer electrically connected to your vehicle and turn on Adaptive Cruise Control, you’ll see an icon in your DIC showing that Adaptive Cruise Control with trailering is on.
• When towing a trailer, Adaptive Cruise Control will change the way it accelerates and brakes to account for the weight of the trailer.
• When towing a trailer with Adaptive Cruise Control, it is important to properly set the Trailer Gain. Check your Owner’s Manual for more information on setting Trailer Gain.
  • You should select Tow/Haul mode when driving down steep hills or mountain grades, or when hauling heavy loads.
• If you turn on Adaptive Cruise Control and do not see the trailering Trailering icon in the DIC when you change your gap setting, your vehicle is not equipped to use Adaptive Cruise Control while trailering or your trailer is not electrically connected. Do not use Adaptive Cruise Control while trailering if this is the case.
• Adaptive Cruise Control should not be used while towing a trailer with an aftermarket trailer brake controller. Aftermarket trailer brake controllers may not function properly with the system.

• The system can only brake so much. Your complete attention is always required while driving.
  
• Adaptive Cruise Control does not steer your vehicle. You must always be in control of vehicle steering.
  
• The system may not react to parked, stopped or slow-moving vehicles. You should always be ready to take action and apply the brakes.
  
• Don’t use the system on winding or hilly roads, on freeway exit or entrance ramps, or when trailering (if your vehicle isn’t equipped with Adaptive Cruise Control with trailering). In these driving conditions, the system may not detect the vehicle ahead.
  
• The system can’t detect traffic lights or traffic signs, so you still need to brake when necessary at intersections and lights.
  
• Avoid using Adaptive Cruise Control when the rear of the vehicle or truck bed is heavily loaded. See your Vehicle Load Limits and Owner’s Manual for more information.
