Camera and radar sensor's field of vision
The camera and radar sensor have limited fields
of vision. In some situations they may detect a
vehicle, pedestrian or cyclist later than expected
or not detect them at all.
Other vehicles that are dirty may be detected
later than others and in dark conditions, motorcy-
cles may be detected late or not at all.
If a text message is displayed in the instrument
panel indicates that the camera or radar sensor
are blocked, it may be difficult for City Safety to
detect a vehicle, pedestrian or cyclist and the
system's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit-
uations in which the camera and/or radar
sensor are blocked. It is therefore essential to
keep the windshield in front the camera/radar
sensor clean and free from snow, ice, etc.
Camera and radar sensor components should
only be serviced or replaced by a trained and
qualified Volvo service technician.
Other limitations
City Safety uses the vehicle's camera and radar
sensor, which have certain general limitations.
See the articles "Camera limitations" and Radar
sensor limitations" for additional information.
WARNING
•
Warnings and braking may be delayed or
not occur at all if traffic, weather or other
conditions prevent the camera and/or
radar sensor from detecting pedestrians,
cyclists or other vehicles correctly.
•
Other vehicles can only be detected in
darkness if their headlights and taillights
are clearly visible.
•
The sensors have a limited range for
pedestrians and cyclists. The system
functions best at speeds up to 30 mph
(50 km/h). For stationary or slow-moving
vehicles, the system functions best at
speeds up to approx. 43 mph (70 km/h).
•
Warnings for stationary or slow-moving
vehicles may be impeded by darkness or
poor visibility.
•
Warnings and braking for pedestrians and
cyclists will not be provided at speeds
above approx. 50 mph (80 km/h).
•
Do not place, attach or mount any objects
on the inside or outside of the windshield
near or over the sensor. This could affect
the camera-based functions.
Action by the driver
Backing up
City Safety is temporarily deactivated while the
vehicle is backing up.
Low speed
City Safety is not activated at very low speeds
(under approx. 3 mph (4 km/h). This means that
the system will not be triggered if your vehicle
approaches a vehicle ahead, such as when park-
ing.
Active driver
Action by the driver always has priority. For this
reason, City Safety may not react or react later
than expected in situations in which the driver is
actively operating the vehicle, even if a collision is
imminent. This is also done to help eliminate
excessive warnings.
