DRIVER SUPPORT
320Do not mount or in any way attach anything on the windshield that could obstruct the camera/radar sensor.
WARNING
•
The camera has the same type of limita- tions as the human eye, i.e., it cannot seeas well in heavy snowfall or rain, thick fogor in heavy blowing dust or snow. In suchconditions, systems depending on thecamera may experience greatly reducedfunctionality or may be temporarily deacti-vated.
• Never place any objects, decals, etc., onthe windshield in front of the camera. Thiscould reduce or block the camera

Camera and radar sensor's field of vision
The camera and radar sensor have limited fields of vision. In some situations they may detect avehicle, large animal, pedestrian or cyclist laterthan 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 sensorare blocked, it may be difficult for City Safety todetect a vehicle, pedestrian or cyclist and thesystem's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit- uations in which the camera and/or radarsensor are blocked. It is therefore essential tokeep the windshield in front the camera/radarsensor clean and free from snow, ice, etc. Camera and radar sensor components should only be serviced or replaced by a trained andqualified Volvo service technician.
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 thatthe system will not be triggered if your vehicleapproaches a vehicle ahead at very low speed,such as when parking.
Active driver
Action by the driver always has priority. For this reason, City Safety may not react or react laterthan expected in situations in which the driver isactively operating the vehicle, even if a collision isimminent. This is also done to help eliminateexcessive warnings.
Other limitations
City Safety uses the vehicle's camera and radar sensor, which have certain general limitations.See the articles "Camera limitations" and "Radarsensor limitations" for additional information.
WARNING
•
Warnings and braking may be delayed or not occur at all if traffic, weather or otherconditions prevent the camera and/orradar sensor from detecting pedestrians,cyclists, large animals or other vehiclescorrectly.
• Other vehicles can only be detected indarkness if their headlights and taillightsare clearly visible.
• The sensors have a limited range forpedestrians and cyclists. The systemfunctions best at relative speeds up to30 mph (50 km/h). For stationary orslow-moving vehicles, the system func-tions best at speeds up to approx.43 mph (70 km/h).
• If there is a risk of colliding with a largeanimal, City Safety can reduce the vehi-cle's speed by up to 9 mph (15 km/h).Warnings and braking are most effectiveat speeds above 43 mph (70 km/h) andless effective at lower speeds.

WARNING
•Warnings for stationary or slow-moving vehicles and large animals may be impe-ded by darkness or poor visibility.
• Warnings and braking for pedestrians andcyclists will not be provided at speedsabove approx. 43 mph (70 km/h).
• Do not place, attach or mount any objectson the inside or outside of the windshieldnear or over the sensor. This could affectthe camera-based functions.
• Objects, snow, ice or dirt in the camera'sfield of vision may result in certain func-tions being reduced or disabled, or theymay respond incorrectly.

Blind Spot Information (BLIS) *
limitations
Blind Spot Information functionality may be reduced in certain situations.
• Dirt, ice and snow on the sensors may reduce functionality and prevent the systemfrom providing warnings.
• Do not attach any objects, tape, decals, etc.,on the surface of the sensors.
• BLIS is deactivated if a trailer is attached tothe vehicle's electrical system.
Maintenance
The BLIS/CTA 5
sensors are located on the
inside of the rear fenders/bumper.
Keep the highlighted area clean (on both sides of the vehicle)
For the system to function optimally, the area over and around the sensors must be kept clean.
CAUTION
Repairs to the BLIS/CTA systems and/or repainting the rear bumper should only bedone by a trained and qualified Volvo servicetechnician.

Cross Traffic Alert (CTA) *
Cross Traffic Alert (CTA) is a supplementary part of Blind Spot Information and is intended todetect vehicles crossing behind your vehiclewhile you are backing up.
When does Cross Traffic Alert function
Principle for CTA
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, for example,when backing out of a parking space. It is primarily designed to detect another vehicle but in certain cases may also detect pedestriansor smaller objects such as bicycles. CTA is only activated when the vehicle is rolling rearward or when the gear selector is put inreverse.

WARNING
•BLIS and CTA are information systems, NOT warning or safety systems and donot function in all situations.
• BLIS and CTA do not eliminate the needfor you to visually confirm the conditionsaround you, and the need for you to turnyour head and shoulders to make surethat you can safely change lanes or backup.
• As the driver, you have full responsibilityfor changing lanes/backing up in a safemanner.

Cross Traffic Alert (CTA) * limitations
CTA functionality may be reduced in certain sit- uations.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see" throughother parked vehicles or obstructions. The following are several examples where CTA's "field of vision" may initially be limited andapproaching vehicles cannot be detected untilthey are too close:
The vehicle is pulled far into a parking space
In angled parking spaces, CTA may be "blind" on one side
CTA's blind area
CTA's "field of vision"
However, as you back your vehicle out of a park- ing space, CTA's "field of vision" expands. Examples of other limitations include:
• Dirt, ice or snow obstructing the sensors may reduce the system's function or make itimpossible to detect other vehicles orobjects.
• CTA is deactivated if a trailer's wiring is con-nected to the vehicle's electrical system.
MaintenanceThe CTA sensors are located on the inside of therear fenders/bumper.
