Heat
If the temperature in the passenger compartment
is very high, the camera and radar sensor may be
temporarily turned off for approx. 15 minutes
after the engine has been started to protect their
electronic components. When the temperature
has cooled sufficiently, the camera and radar
sensor will restart automatically.
The visual warning signal may also be temporarily
disabled due to high passenger compartment
temperatures caused by strong sunlight.
Warnings may not be given if the distance to the
vehicle ahead is short and the driver is actively
operating the vehicle (clearly depressing a pedal
or turning the steering wheel).
Reduced visibility
City Safety's functions may be greatly impeded or
deactivated by e.g., intense snowfall or rain, in
dense fog, in very dusty conditions or if there is
blowing snow in front of the vehicle. Condensa-
tion, ice, snow or dirt on the windshield may also
reduce the system's functionality.
NOTE
•
Keep the windshield in front of the radar
sensor free of ice, snow, dirt, etc.
•
Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sensor.
Keep the hood free of ice and snow.
•
Do not mount or in any way attach any-
thing on the windshield that could
obstruct the radar sensor.
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.
Camera and radar sensor components should
only be serviced or replaced by a trained and
qualified Volvo service technician.
Other limitations
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.
