Low speed
City Safety is not activated at very low speeds - below 4 km/h (3 mph) - and the system there-fore does not intervene in situations where yourcar is approaching a vehicle ahead very slowly,e.g. when parking.
Active driver
Driver commands are always prioritised, which is why City Safety does not intervene or postponewarning/intervention in situations where thedriver is steering and accelerating in a decisivemanner, even if a collision is unavoidable. Active and aware driving behaviour can therefore delay a collision warning and intervention in orderto minimise unnecessary warnings.
Miscellaneous
WARNING
Warnings and brake interventions could be implemented late or not at all if a traffic situa-tion or external influences mean that the cam-era and radar unit cannot detect pedestrians,cyclists, large animals or vehicles correctly. For vehicles to be detected at night, their headlamps and rear lamp cluster must beswitched on and shining clearly. The camera and radar unit has a limited range for pedestrians and cyclists. The system canprovide effective warnings and brake interven-tions as long as the relative speed is below50 km/h (30 mph). For stationary or slow-moving vehicles, warnings and brake interven-tions are effective at vehicle speeds up to70 km/h (43 mph). Speed reduction for largeanimals is less than 15 km/h (9 mph) andcan be achieved at vehicle speeds above70 km/h (43 mph). The warning and brakeintervention for large animals is less effectiveat lower speeds. Warnings for stationary or slow-moving vehi- cles and large animals could be disengageddue to darkness or poor visibility. Warnings and brake interventions for pedes- trians and cyclists are deactivated at vehiclespeeds exceeding 70 km/h (43 mph). Do not place, stick or mount anything on the outside or inside of the windscreen in front ofor around the camera and radar unit — thiscan interfere with camera-dependent func-tions.
Objects, snow, ice or dirt in the area of the camera sensor may reduce its function, fullydeactivate it or give incorrect functionresponse.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

Limitations of Blind Spot Information*
The Blind Spot Information (BLIS) function may have limitations in certain situations.
Examples of limitations:
• Dirt, ice and snow covering the sensors may reduce the functions and deactivate alerts.
• BLIS is deactivated when a trailer is con-nected to the car

Limitations of Cross Traffic Alert The Cross Traffic Alert (CTA) function may have limitations in certain situations.
CTA does not perform optimally in all situations but has some limitations. For example, the CTAsensors cannot "see" through other parked vehi-cles or obstructing obstacles. Here are some examples of situations where CTA

Keep the surface clean - on both the left and right-hand sides of the car 18
.
To ensure optimal functionality, the surfaces in front of the sensors must be kept clean. Do not affix any objects, tape, labels or similar within the area of the sensors.
IMPORTANT
Repair of the BLIS and CTA functions' com- ponents or repainting the bumpers must onlybe performed by a workshop - an authorisedVolvo workshop is recommended.

Park Assist*
Parking assistance assists the driver when manoeuvring in tight spaces by indicating thedistance to obstacles by acoustic signals com-bined with graphics on the centre display.
Screen view showing obstacle zones and sensor sectors.
The centre display shows an overview of the rela- tionship between the car and detected obstacles. The highlighted sector indicates the location of the obstacle. The closer the car symbol is to ahighlighted sector box, the shorter the distancebetween the car and detected obstacle. The shorter the distance to the obstacle, the faster the signal sounds. Other sound from theaudio system is muted automatically. The acoustic signal for obstacles ahead and to the sides is active when the car is moving butstops after the car has been stationary for approx. 2 seconds. The acoustic signal for obsta-cles behind is also active when the car is station-ary. At a distance within 30 cm from an obstacle behind or in front of the car, the tone is constantand the active sensor's field closest to the carsymbol is filled. The volume of the parking assistance signal can be adjusted while the signal is sounding by means of the [
>II] knob on the centre console.
Adjustment can also be performed in the top view's
Settings menu option.
NOTE
• Acoustic warnings are only given for objects directly on the vehicle's route.
WARNING
•Parking assistance does not relinquish the driver's own responsibility duringparking.
• The sensors have blind spots whereobstacles cannot be detected.
• Be aware of e.g. people or animals nearthe car.
Backwards
NOTE: The illustration is schematic - details may vary depending on car model.
The sensors for reverse are activated if the car rolls backward without a gear engaged or whenthe gear lever is moved to reverse position. The measuring range starts approx. 1.5 metres behind the car. When reversing with a hitched trailer, parking assistance backward is deactivated automatically.
NOTE
When reversing with e.g. a trailer or bike car- rier on the towbar - without Volvo genuinetrailer wiring - parking assistance may need tobe switched off manually in order that thesensors do not react to them.

Along the sides
Parking assistance side sensors are activated automatically when the engine is started. Theyare active at speeds below 10 km/h (6 mph). The measuring range starts approx. 30 cm from the sides. The acoustic signal for obstacles onthe sides comes from the side loudspeakers.
Forwards
NOTE: The illustration is schematic - details may vary depending on car model.
The front parking assistance sensors are acti- vated automatically when the engine is started.The front sensors are active at speedsbelow 10 km/h (6 mph). The measuring range starts approx. 0.8 metres in front of the car.
NOTE
Parking assistance is deactivated when the parking brake is applied or P mode is
selected in a car with an automatic gearbox.
IMPORTANT
When auxiliary lamps are fitted: Remember that these must not obscure the sensors - theauxiliary lamps may then be perceived as anobstacle.

Activating/deactivating Parking assistance*
The Parking assistance function can be acti- vated/deactivated.
The front and side parking assistance sensors are activated automatically when the engine isstarted. The rear sensors activate if the car rollsbackwards or if reverse gear in engaged.
The function is activated/deac-tivated in function view in thecentre display. Parking assistance can also be activated/deactivated from thecamera views.

Limitations of Parking assistance *
The Parking assistance function may have limita- tions in certain situations.
NOTE
Since a towbar is configured with the car's electrical system, towbar protrusion isincluded when the function measures the dis-tance to an object behind the car.
IMPORTANT
Objects e.g. chains, thin glossy poles or low barriers may be in the "signal shadow" andare then temporarily not detected by the sen-sors - the pulsating tone may then unexpect-edly stop instead of changing over to theexpected constant tone. The sensors cannot detect high objects, such as projecting loading docks.
• In such situations, pay extra attention andmanoeuvre/reposition the car particularlyslowly or stop the current parkingmanoeuvre - there may be a high risk ofdamage to vehicles or other objects sinceinformation from the sensors is notalways reliable in such situations.
IMPORTANT
In certain conditions the parking assistance system may produce incorrect warning sig-nals that are caused by external soundsources that emit the same ultrasonic fre-quencies that the system works with. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles, etc.
Maintenance
Location of the parking sensors 24
.
For parking assistance to work optimally, the parking assistance sensors must be cleaned reg-ularly with water and car shampoo.
