Volkswagen VW Adaptive Cruise Control in short ACC is one of the driver assistant features now available as a new function on VW vehicles. The system is designed to assist you when driving both short and long distances. When you become accustomed to having the system activated you will find driving safer and easier. To enjoy the benefits of the system and improve your driving experience please read below, to understand how the system works and how to adjust it to suit your individual driving style.
How does Volkswagen adaptive cruise control work?
The ACC system works in two ways, by maintaining a set speed and also by maintaining a set distance between your vehicle and the vehicle in front of you. Radar enables the sensors on your vehicle to detect the distance of the vehicle in front of you and the system is activated between speeds from approximately 20 mph up to 95 mph. You can choose to adjust the adaptive cruise control distance, and when a vehicle is moving slower than you the system automatically decreases the speed of your vehicle. In addition, when a vehicle suddenly stops or starts to move slowly in front of you, the system is also capable of activating the brakes, if required.
How to use adaptive cruise control in your Volkswagen car?
You will then be able to select the speed you want the cruise control to maintain. To do this you need to press the set button and if you look at the instrument cluster, the speed you have selected will then be visible.
The next step is adjusting the following distance by setting a time interval.
You will find the “Adaptive Distance” button located on your steering wheel. The time interval is set by pressing this button and can be altered by pressing the plus or minus buttons, this will allow you to select between the five available time interval options.
How to deactivate the Adaptive Cruise Control system
There are two ways to deactivate the system; on your steering wheel you can press the cruise control or you can use the brakes. When you want to reactivate the cruise control, simply press the button labeled “Resume” located on the steering wheel and the most recent speed selected will then be reset.
But if your VW ACC is deactivated and can't be enabled via steering wheel or other ways it might be that radar has malfunction and needs to be replaced.
Additional driving assistant package
In addition to the adaptive cruise control system, the other available features of the driving assistant package include:
The blind spot monitor feature- this uses sensors to notify you if there is a vehicle in your blind spot when you want to change lanes.
The lane assist system- this senses if the vehicle starts to drift and alerts you to change your steering.
The park assist system- this will check if your vehicle has enough room to fit into a gap and will direct your steering to assist you with parking in the space.
The front assist system- this consists of a collection of features. Forward collision warning, autonomous emergency braking, and pedestrian monitoring systems work in conjunction to make you aware of any vehicles or pedestrians in front of you and when necessary will apply the brakes to avoid a collision.
The rear traffic alert feature- this uses sensors located at the back of your vehicle to make you aware of any vehicles or pedestrians behind you applying the brakes when needed to prevent impact.
