Common limitations for camera and radar
The marked area must be cleaned regularly and kept free from stickers, objects, shade film, etc.
The camera unit is placed inside the upper section of the windscreen together with the car's radar unit.
Do not place, stick or mount anything on the inside or outside of the windscreen, in front of or around the camera and radar unit – this may interfere with camera and radar-based functions. This may result functions being reduced, being switched off completely or giving incorrect function responses.
At very high temperatures the camera and radar unit can temporarily be switched off for about 15 minutes after the engine is started so as to protect the unit's electronics. The camera and radar unit restarts automatically when the temperature has fallen sufficiently.
If not rectified it can lead to reduced performance for the driver support systems that use the camera and radar unit. This may result functions being reduced, being switched off completely or giving incorrect function responses.
The following is also applicable so as not to risk incorrect function for the driver supports that use the radar unit:
- If a scratch, crack or stone chip appears on the windscreen in front of any of the "windows" for the camera and radar unit and covers an area of approx. 0.5 × 3.0 mm (0.02 × 0.12 in.) or more, a workshopmust be contacted so that the windscreen can be replaced.
An authorised Volvo workshop is recommended.
- Volvo recommends not repairing cracks, scratches or stone chips in the area in front of the camera and radar unit – the entire windscreen should be replaced instead.
- Before replacing a windscreen, contact a workshop
An authorised Volvo workshop is recommended.to verify that the correct windscreen has been ordered and will be fitted.
- The same type of windscreen wipers or windscreen wipers approved by Volvo must be fitted when the windscreen is replaced.
- When replacing the windscreen, the camera and radar unit must be recalibrated by a workshop
An authorised Volvo workshop is recommended.to ensure the functionality of all the camera and radar-based systems in the car.
Further limitations for radar
The radar unit's ability to detect a vehicle ahead is greatly reduced if the speed of the vehicle ahead is very different to the speed of your own car.
Limited field of vision
The radar unit has a limited field of vision. In some situations another vehicle is not detected, or the detection is made later than expected.

Low trailer in radar shadow
Low trailers can also be difficult for the radar unit to detect, or are not detected at all - the driver should therefore be particularly careful when driving behind low trailers when the adaptive cruise control* or Pilot Assist* is activated.
Further limitations for camera
The cameras have limitations similar to the human eye, i.e. may "see" worse in for example intense snowfall or rain, dense fog, heavy dust storms and snow flurries. Under such conditions, the functions of camera-dependent systems could be significantly reduced or temporarily disengaged.
Strong oncoming light, reflections in the carriageway, snow or ice on the road surface, dirty road surfaces or unclear lane markings can also significantly reduce camera function when it is used to scan the carriageway to detect pedestrians, cyclists, large animals and other vehicles.
Further limitations for Park assist camera*
There are "blind" sectors between the cameras' fields of vision.
In the park assist camera's 360° view* obstacles/objects may "vanish" in the gaps between the individual cameras.
Pay attention to the possibility that, even if it only looks like a relatively small part of the image is obscured, a relatively large sector could be hidden from view. An obstacle could thereby go undetected until the car is very close to it.
The camera image is adjusted automatically according to prevailing light conditions. Because of this, the image may vary slightly in brightness and quality. Poor light conditions can result in reduced image quality.
A bike carrier or other accessory mounted on the rear of the car could obscure the camera's view.
