Adaptive Cruise Control (ACC) -> Troubleshooting for Your Volkswagen Polo SUV Seventh Generation (2021-2025)

- 1 km/h (1 mph):  
Press the  
button, only when ACC is active.  
+ 10 km/h (5 mph):  
Press the button. The first time it is pressed, it jumps to the next higher ten (km/h) or five (mph) increment.  
- 10 km/h (5 mph):  
Press the button. The first time it is pressed, it jumps to the next lower ten (km/h) or fives (mph) increment  
Press and hold the or button to continuously change the stored speed.  
WARNING  
ACC cannot detect all driving situations correctly. If you do not maintain the minimum distance to the vehicle in front or if the  
difference in speed between the vehicle in front and your own vehicle is so great that the braking action of ACC is insufficient, you are  
in danger of colliding with the vehicle in front. This can cause serious injuries or death.  
Always be prepared to brake the vehicle yourself.  
Press the accelerator to override Adaptive Cruise Control. ACC does not brake automatically in this case.  
Observe any country-specific regulations relating to the minimum distance.  
Always set a larger distance in wet or snowy conditions or when visibility is poor.  
Setting the system behaviour  
You can influence how dynamically ACC reacts:  
Vehicles with driving profile selection:  
Set preferred driving profile.  
Vehicles without driving profile selection:  
Select the desired gearbox program in the Assist systems menu of the Infotainment system.  
Some settings can be stored in the user accounts of the personalisation function and therefore change automatically when the  
user account changes.  
ACC not available  
The indicator lamp lights up yellow. A message will also appear on the instrument cluster display.  
The radar sensor is dirty. Clean the radar sensor (→ Vehicle care).  
The view of the radar sensor is impaired due to the weather conditions, e.g. snow, or due to detergent deposits or coatings. Clean  
the radar sensor (→ Vehicle care).  
The view of the radar sensor is impaired by add-on parts, number plate holders with trim frames or stickers. Keep the area around  
the radar sensor free (→ Accessories and replacement parts).  
The radar sensor has been displaced or damaged, e.g. due to damage to the front of the vehicle. Check whether damage is visible  
(→ Accessories and replacement parts).  
Fault or malfunction. Switch off and restart the engine.  
Paint work or structural modifications were carried out on the front of the vehicle (→ Repairs and technical modifications).  
The genuine Volkswagen badge is not used. Volkswagen recommends using Volkswagen Genuine Parts® or Volkswagen Genuine  
Accessories, which you can purchase from an authorised Volkswagen repairer.  
If the problem persists, go to a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.  
The ACC does not function as expected  
The radar sensor is dirty. Clean the radar sensor (→ Vehicle care).  
The ultrasound sensors are dirty, covered or damaged. Clean the ultrasound sensors (→ Vehicle care).  
Keep the area around the ultrasound sensors clear and check whether there is any visible damage (→ Accessories and replacement  
parts).  
The system limits have been exceeded (→ Adaptive Cruise Control (ACC)).  
The brakes have overheated, control was cancelled automatically. Allow the brakes to cool down and check their functionality again.  
If the problem persists, go to a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.  
Depending on the malfunction, additional information may be displayed in the vehicle status (→ Vehicle settings menu).  
Control cannot be started  
Make sure that the following conditions are met:  
Vehicles with a manual gearbox: A forward gear other than 1st gear has been engaged and the speed is at least 25 km/h (16 mph).  
Vehicles with an automatic gearbox: A position has been selected for driving forward.  
The brake lights on the vehicle are working.  
The brake lights on the electrically connected trailer are in working order.  
ESC is not performing a control intervention.  
If control is to be started while the vehicle is stationary, depress the brake pedal. Otherwise, do not depress the brake pedal.  
Unusual noises during automatic braking  
This is normal and is not a fault.  
The predictive cruise control adapts the vehicle speed to detected speed limits and the course of the road ahead, e.g. bends,  
junctions, roundabouts.  
The predictive cruise control is an extension of ACC and makes use of Dynamic Road Sign Display and navigation data provided in the  
Infotainment system.  
The predictive cruise control function is dependent on the equipment level and is not available in all countries.  
WARNING  
The predictive cruise control system is not a substitute for the full attention of the driver and operates only within the limits of the  
system. The predictive cruise control system cannot detect all applicable speed limits and may not react or may react with a delay or  
in an undesired way. If you do not pay due attention, there is a risk of accidents and serious or even fatal injuries.  
Always pay due attention and do not rely exclusively on the system. The driver is responsible for the stored vehicle speed at all  
times.  
Observe the system limits (→ Predictive cruise control system).  
Ensure that your speed is always appropriate for the current visibility, weather and road/traffic conditions.  
Keep the navigation data up-to-date.  
Always observe the maximum speed limit.  
Please note that the speeds regulated by the system do not necessarily correspond to your driving style.  
Also observe the system limits and the information for ACC.  
The system also uses navigation data even if the vehicle does not have a navigation system. Keep the navigation data up-to-  
date (→ Navigation). If you have any questions, please contact a suitably qualified workshop. Volkswagen recommends using  
an authorised Volkswagen repairer.
