Toyota Radar Cruise Control Unavailable

As one of the most popular car brands in the world, Toyota is always looking for ways to improve the driving experience for their customers. One feature that they have been working on is radar cruise control. This system uses sensors to detect the speed and distance of the car in front of you, so it can automatically adjust your speed to maintain a safe following distance.

However, this system is not yet available on all Toyota models.

If your Toyota is equipped with radar cruise control, you may have noticed that the feature has been unavailable recently. This is because Toyota issued a recall for certain vehicles that were equipped with the feature. The recall was issued because it was discovered that there was a potential issue with the software that could cause the radar cruise control to malfunction.

As a result, Toyota has disabled the feature until they can develop and release a software update to fix the problem. In the meantime, you’ll just have to enjoy your Toyota without radar cruise control.

Why Does My Radar Cruise Control Say Unavailable?

If you’re driving a car with radar cruise control and it says “unavailable,” there are several potential reasons why. The most likely explanation is that the radar sensor, which is located behind the front grill, is obstructed. This can happen if there’s debris or ice on the sensor, or if the sensor gets dirty over time.

Another possibility is that the radar cruise control system itself is malfunctioning. In this case, you should take your car to a dealer or qualified mechanic to have it checked out.

How Do I Fix Adaptive Cruise Temporarily Unavailable?

If you’re experiencing the “Adaptive Cruise Temporarily Unavailable” error message on your car’s display, there are a few things you can try to fix the issue. First, check to make sure that all of the sensors on your car are clean and free of debris. If they’re dirty, they may not be able to properly detect other vehicles on the road, causing the adaptive cruise control system to become unavailable.

Next, try restarting your car. This will reset all of the electronic systems in your vehicle and may clear up any glitches that were causing the adaptive cruise control system to be unavailable. If neither of these solutions works, then you may need to take your car to a dealership or service center for further diagnosis and repairs.

What Causes the Adaptive Cruise Control to Stop Working?

If your adaptive cruise control system isn’t working properly, there are a few potential causes. One possibility is that the radar sensor is dirty or obstructed. This sensor is responsible for detecting objects in front of the vehicle, so if it can’t see clearly, the system won’t work correctly.

Another possibility is that there’s an issue with the vehicle’s speed sensors. These sensors send information to the cruise control system about how fast the car is going, so if they’re not working properly, the system won’t be able to maintain a consistent speed. Finally, a software glitch could also be to blame.

If there’s an error in the code that runs the adaptive cruise control system, it could cause problems with its operation.

If you’re having trouble with your adaptive cruise control, it’s best to take it to a qualified technician for diagnosis and repair. They’ll be able to pinpoint the exact cause of the problem and get your system up and running again quickly.

Can You Disable Radar Cruise Control Toyota?

Radar cruise control is a driver assistance feature that uses radar to detect vehicles in front of your car and automatically adjust your speed to maintain a safe following distance. This can be a useful feature for highway driving, but you may want to disable it under certain circumstances. For example, if you’re driving in stop-and-go traffic or in bad weather, you may find that radar cruise control doesn’t work well and can actually be more of a hindrance than a help.

To disable radar cruise control on Toyota vehicles, press the “Cancel” button on the steering wheel. This will turn off the system and allow you to resume manual control of your vehicle’s speed.


Radar Cruise Control Unavailable See Owners Manual

If your car is equipped with radar cruise control, you may have noticed a message on your dash that says “Radar Cruise Control Unavailable – See Owner’s Manual.” This message is displayed when the system is not able to properly function and needs to be disabled. There are a few reasons why this message may appear:

1. The vehicle ahead of you has moved out of the system’s range. Radar cruise control needs to be able to see the vehicle ahead in order to maintain a set distance. If the vehicle moves out of range, the system will disable itself.

2. There is something blocking the radar sensor. This could be something as simple as dirt or snow on the sensor, or it could be a more permanent obstruction like a plastic cover over the sensor (as is common on some aftermarket grilles). 3. The radar sensor has failed.

This is less common, but it can happen if there is an issue with the wiring or software. In this case, you’ll need to take your car to a dealer for diagnosis and repair. If you see this message pop up, don’t worry – it’s not necessarily indicative of a problem with your car.

However, if it happens frequently, it’s worth taking your car in for service just to make sure everything is working properly.


According to Toyota, radar cruise control will be unavailable on some of its vehicles due to a software issue. The problem affects the Pre-Collision System (PCS) and Dynamic Radar Cruise Control (DRCC) systems, and is caused by a software error that could potentially cause the systems to malfunction. As a result, Toyota has advised owners of affected vehicles to avoid using these features until the problem can be fixed.

The company is currently working on a software update that will resolve the issue, but it is unclear when this will be released. In the meantime, Toyota recommends that drivers use caution when operating their vehicles in areas where PCS or DRCC are active.
