2021 Polestar 1 Camera and Radar Sensor
Camera
Location of the camera
The camera is used by the following functions:
- Adaptive Cruise Control*
- Pilot Assist*
- Lane Keeping Aid
- Steering assistance at risk of collision
- City Safety
- Driver Alert Control
- Traffic sign information
- Active high beam
- Park Assist System
Camera/radar sensor limitations
Camera and radar sensor limitations
The area marked in the illustration must be cleaned regularly and kept free of decals, objects, solar film, etc. The camera is located on the upper interior section of the windshield along with the radar sensor. Do not place, affix or mount anything on the inside or outside of the windshield, or in front of or around the camera and radar sensor – this could disrupt camera and radar-based functions. It could cause functions to be reduced, deactivated completely or to produce an incorrect function response.High temperatures
If the temperature in the passenger compartment is very high, the camera/radar sensor will switch off temporarily for approx. 15 minutes after the engine is started to protect its electronic components. When the temperature has cooled sufficiently, the camera/radar sensor will automatically restart.
Damaged windshield
Failure to take action could result in reduced performance for the driver support systems that use the camera and radar unit. It could cause functions to be reduced, deactivated completely or to produce an incorrect function response.
To avoid the risk of malfunction of the driver support systems that use the radar sensor, the following also apply:
- If there are cracks, scratches or stone chips on the windshield in front of any of the camera and radar sensor “windows” and this covers an area of about 0.5×3.0 mm (0.02×0.12 in.) or more, contact Polestar Customer Support to have the windshield replaced.
- Polestar advises against repairing cracks, scratches or stone chips in the area in front of the camera and radar sensor – the entire windshield should instead be replaced.
- Before replacing the windshield, contact Polestar Customer Support to verify that the right windshield has been ordered and installed.
- The same type of windshield wipers or wipers approved by Polestar should be used for replacement.
- If the windshield is replaced, the camera and radar sensor must be recalibrated by a workshop to help ensure proper functioning of all of the vehicle’s camera and radar-based systems. Contact Polestar Customer Support.
Additional radar limitations
The radar sensor’s ability to detect a vehicle ahead is significantly reduced if the speed of the vehicle ahead differs greatly from your vehicle’s speed.
Limited field of vision
The radar sensor has a limited field of vision. In some situations, it may detect a vehicle later than expected or not at all.
The radar sensor’s field of vision
- The radar sensor’s detection of vehicles very close to your vehicle may be delayed in certain situations, e.g. if a vehicle pulls in between your vehicle and the vehicle directly ahead.
- Small vehicles, such as motorcycles, or vehicles that are not driving in the center of the lane may remain undetected.
- In curves, the radar may detect a different vehicle or lose sight of a target vehicle.
Low trailers
Low trailer in the radar shadow Low trailers may also be difficult or even impossible for the radar to detect. The driver should be extra alert when driving behind vehicles towing low trailers when Adaptive Cruise Control or Pilot Assist is activated.
Additional camera limitations
Cameras have the same limitations as the human eye. In other words, their “vision” is impaired by adverse weather conditions such as heavy snowfall/rain, dense fog, swirling dust/snow, etc. These conditions may reduce the function of systems that depend on the camera or cause these systems to temporarily stop functioning.
Strong sunlight, reflections from the road surface, ice or snow covering the road, a dirty road surface, or unclear lane marker lines may drastically reduce the camera’s ability to detect the side of a lane, a pedestrian, a cyclist, a large animal or another vehicle.
Additional Park Assist Camera limitations
There are “blind” sectors between the cameras’ fields of vision. With the Park Assist Camera’s 360° view selected, objects/obstacles may not be detected if they are located in the “joints” where the edges of the individual camera views meet.
Even if it seems as though only a fairly small section of the screen image is obstructed, this may mean that a relatively large sector is hidden and an obstacle there may not be detected until it is very near the vehicle.
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions. This means that the brightness and quality of the image may vary slightly. Poor lighting conditions may result in reduced image quality.
Camera/radar unit symbols and messages
Sensor blocked
If this symbol and the message Windscreen sensorSensor blocked, see Manual is displayed in the instrument panel, it means that the camera and radar sensor are unable to detect other vehicles, cyclists, pedestrians and large animals in front of the vehicle and that the vehicle’s camera and radar-based functions may be obstructed.
The following table shows some of the situations that can cause the message to be displayed, and suggested actions:
| Cause | Action |
|---|---|
| The area of the windshield in front of the camera/radar sensor is dirty or covered by ice or snow. | Clean the windshield in front of the camera/radar sensor and remove dirt, ice and snow. |
| Thick fog, heavy rain or snow is blocking the radar signals or the camera’s range of visibility. | No action. Heavy precipitation may sometimes prevent the camera/radar sensor from functioning. |
| Water or snow is spraying/swirling up and blocking the radar signals or the camera’s range of visibility. | No action. Very wet or snow-covered roads may sometimes prevent the camera/radar sensor from functioning. |
| There is dirt between the inside of the windshield and the camera/radar sensor. | The windshield on the inside of the camera casing needs to be cleaned – contact Polestar Customer Support. |
| Bright sunlight. | No action. The camera/radar sensor will reset automatically when lighting conditions improve. |
Defective camera
If a camera sector is dark and contains this symbol, this indicates that the camera is not functioning properly.
A dark camera sector may also be displayed in the following situations, but without the defective camera symbol:
- a door is open
- the trunk lid is open
- a rearview mirror is folded in
Radar sensor
The radar sensor is used by the following functions:
- Distance Alert*
- Adaptive Cruise Control*
- Pilot Assist*
- Lane Keeping Aid
- City Safety
Any modifications to the radar sensor may make its use illegal.

For detailed information on type approval, contact Polestar Customer Support.
Recommended camera and radar sensor maintenance
Dirt, ice and snow covering the sensors could cause false warnings, reduced function, or no function.
- For best possible performance, it is important to keep the areas in front of the sensors clean.
- Do not attach any objects, tape or decals to the surface of the sensors.
- Clean the camera lenses regularly using lukewarm water and car washing detergent. Wash gently to avoid scratching the lens.
Only a workshop may perform maintenance on driver support components – contact Polestar Customer Support.
