Why is my Adaptive Cruise Control Not Working?

One of the primary reasons why your ACC may stop working is due to faulty parts such as the spiral cable, vacuum actuator, or vacuum hoses. If you experience a sudden loss of ACC, you should avoid using it and take your vehicle to a certified auto mechanic for diagnosis and repair.

What are the signs of a failing cruise control?

If you notice any of the following signs, your ACC may be failing:

  • The system does not maintain a consistent speed when set.
  • The system does not engage.
  • Dashboard cruise control light issues.

How much does it cost to fix Adaptive Cruise Control?

The cost of fixing ACC can vary depending on the make and model of your vehicle, as well as the severity of the issue. On average, costs can range from $125 to $400 to fix cruise control-related problems.

Why does my cruise control say temporarily unavailable?

A “Adaptive Cruise Temporarily Unavailable” message may appear if any of the radars or the camera becomes blocked or misaligned. This can cause the ACC to be disabled, and you’ll need to have the problem fixed before you can use the feature again.

How do I enable Adaptive Cruise Control?

Enabling ACC is simple. To turn it on, press the cruise control ON/OFF button on the steering wheel. When the system is turned on, you’ll see a white adaptive cruise control icon in your cluster display or on your Head-Up Display, if your vehicle has that feature.

What causes cruise control malfunction?

Cruise control malfunctions can be caused by a variety of issues, ranging from serious problems like a weak car battery or a malfunctioning electronic control unit, to simple issues like a faulty wire or a blown fuse.

Can you deactivate Adaptive Cruise Control?

Yes, ACC can be deactivated and switched off. To do so, press the steering wheel button. The symbol and indicators will turn gray, and the ACC will be set in standby mode. The indicator for time interval and symbol for target vehicle, if activated, will also be switched off.

How do I fix adaptive cruise temporarily unavailable?

For most vehicles, the majority of Adaptive Cruise Temporarily Unavailable issues can be resolved by performing the Multi Axis Sensor learn. If the issue persists, you can perform the Long Range Radar Learn, as outlined in the Radar Sensor Module – Long Range Programming and Setup procedure in Service Information.

How do I reset my Adaptive Cruise Control?

Resetting ACC is simple. To do so, press and hold down the interval button (vehicle with four bars behind it) for approximately one second. Cruise Mode Selected will appear in the instrument panel. Press and hold the interval button again to reset the ACC feature.

Where is the Adaptive Cruise Control sensor located?

For most vehicles, the ACC camera is located behind the windshield, near the rearview mirror. This camera is responsible for tracking the speed and distance of the vehicles in front of your car. It is important to keep the windshield clean for the camera to work optimally.

Dirt, grime, or any other debris on the windshield may block or obstruct the camera’s view, which can cause the ACC to display a “Temporarily Unavailable” message.

In addition to the camera, some vehicles also use radar sensors located in the front grille or bumper to enhance the accuracy of ACC. These radar sensors work by sending out a signal that bounces back off the vehicle in front of you.

The time it takes for the signal to return helps the system determine the speed and distance of the vehicle in front. It is equally important to keep the grille or bumper area clean to ensure the sensors work correctly.

How to Turn On Adaptive Cruise Control

To turn on the adaptive cruise control in your vehicle, follow these simple steps:

Locate the cruise control button on your steering wheel. The button is typically labeled with a cruise control symbol, which is a car with a speedometer in the middle.

Press the button to turn on the adaptive cruise control. A white ADAPTIVE CRUISE CONTROL icon will appear in your vehicle’s cluster display or head-up display, if your vehicle has that feature.

Once the adaptive cruise control is on, you can set your desired speed by pressing the SET button or the accelerator pedal.

The adaptive cruise control system will automatically adjust your vehicle’s speed to maintain a safe distance from the vehicle in front of you.

It’s important to keep in mind that the adaptive cruise control system is not a substitute for safe and responsible driving. Always stay alert and pay attention to road conditions, other vehicles, and traffic signals.


Adaptive cruise control is a valuable feature for drivers who want to maintain a safe and consistent speed on the road. If you’re experiencing issues with your adaptive cruise control, it’s important to seek help from a certified auto mechanic. 

They can diagnose and repair any problems, ensuring that your adaptive cruise control system is working properly. By following the steps outlined in this blog post, you can ensure that your adaptive cruise control is functioning correctly and you’re able to enjoy a safe and comfortable driving experience.


Does cruise control save fuel?

Utilizing cruise control in your vehicle can help increase fuel efficiency and can result in an average fuel savings of 7-14%. This is because the feature helps maintain a consistent speed, reducing the need for acceleration and deceleration which can consume more fuel.

Does adaptive cruise control drain the battery?

No, adaptive cruise control will not drain your vehicle’s battery. However, it is important to note that if you leave other electrical components switched on for an extended period, it could potentially drain your battery. But ACC alone does not consume significant power from the battery.
