The driver is responsible for ensuring that the vehicle maintains a suitable distancefrom such obstacles.
• The camera and radar sensors do nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects that completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is lim-ited in force, which means that it cannotalways help the driver to steer and keepthe vehicle within the lane.
• Pilot Assist is switched off if the powersteering is working with reduced power -e.g. during cooling due to overheating(see section "Speed-dependent steeringforce").
The driver can always correct or adjust steeringassistance provided by Pilot Assist by turning thesteering wheel to the desired position.
Steep roads and/or heavy loadsPilot Assist is primarily intended to be driven onflat roads. The function may not be able to main-tain the correct time interval to the vehicle aheadwhen driving down steep hills. The driver should be extra attentive and prepared to apply thebrakes.
• Do not use Pilot Assist if the vehicle is carry-ing a heavy load or towing a trailer.
NOTE
Pilot Assist cannot be activated if a trailer, bike carrier or similar is connected to thevehicle electrical system.
Other limitations
•
The Off Road drive mode cannot be
selected when Pilot Assist is activated.
NOTE
The function uses the vehicle's camera unit, which has some general limitations – see thesection "Camera unit limitations".
NOTE
The function uses the vehicle's radar unit, which has some general limitations – see thesection "Radar unit limitations".

Radar sensor limitations
The radar sensor used by several of the driver support functions has certain limitations, whichalso affect the functions using the radar sensor.
Obstructed camera
The area marked in the illustration must be kept free of decals, objects, solar film, etc. 70
The radar sensor is located on the upper interior section of the windshield along with the camera.
CAUTION
Do not place, affix or mount anything on the inside or outside of the windshield, or in frontof or around the camera and radar unit – thiscould disrupt camera and radar-based func-tions. It could cause functions to be reduced, deac- tivated completely or produce an incorrectfunction response.
If this symbol and the message "Windscreen sensor Sensor
blocked, see Owner's manual" is
displayed in the instrument panel, it
means that the camera and radar sensor are unable to detect other vehicles, cyclists, pedes-trians and large animals in front of the vehicleand that the vehicle's camera and radar-basedfunctions may be obstructed, reduced, completelydisabled or providing inaccurate responses.
The following table shows some of the situations that can cause the message to be displayed, and suggested actions:
CauseAction
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, iceand snow.
Thick fog, heavy rain or snow is blocking the radar signals or the camera'srange of visibility. No action. Heavy precipitation may sometimes prevent the camera/radar sensorfrom functioning.

3 - Auto-brake
The automatic braking function is activated at the last moment. If the driver has not taken evasive action by this stage and a collision is imminent, the automaticbraking function will be triggered. This occurswhether or not the driver is pressing the brakepedal. Full braking force will be applied to reducethe speed at impact or reduced braking effect willbe applied if this is sufficient to avoid the colli-sion. The seat belt tensioners may be activated along with the automatic braking function. See "Seatbelt tensioners" for more information. In certain situations, auto-braking may begin with a limited braking force before applying full brak- ing force. If City Safety has prevented a collision, the vehi- cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with a slower-moving vehicle ahead, yourspeed will be reduced to that vehicle's speed. Auto-braking can always be cancelled if the driver presses hard on the accelerator pedal.
NOTE
When City Safety activates the brakes, the brake lights come on.
When City Safety applies the brakes, a text mes- sage will appear in the instrument panel to notifythe driver that the function is/was activated.
WARNING
City Safety may not be used to change how the driver operates the vehicle. The drivermust not only rely on City Safety to brake thevehicle.

Setting a warning distance for CitySafety
City Safety is always active, but the function's warning distance can be adjusted.
NOTE
The City Safety function cannot be deacti- vated. It is activated automatically each timethe engine/electric motor is started.
The alert distance determines the sensitivity of the system and regulates the distance at whichthe light, sound and brake pulsations will be acti-vated. To select warning distance:
1. Select
SettingsMy CarIntelliSafe in
the center display's Top view.
2. Under
City Safety Warning, tap Late,Normal or Early to set the desired warning
distance.
If the driver feels that the
Early setting is giving
too many warnings or finds them irritating, the
Normal or Late warning distance settings can
be selected instead. If the driver feels that the warnings are too fre- quent and distracting, the warning distance canbe reduced. This will reduce the total number ofwarnings, but it will also result in City Safety pro-viding warnings at a later stage.

City Safety limitations
City Safety functionality may be reduced in cer- tain situations.
Surroundings
Low objects
Hanging objects, such as flags for overhanging loads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood, may limit City Safety function-ality.
Slippery road conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con- trol (ESC 77
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may be difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.
Heat
If the temperature in the passenger compartment is high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer- tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected. Vehicles that are dirty may be detected later than clean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all. If a text message displayed in the instrument panel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced. Text messages may not be displayed for all situa- tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.
CAUTION
Maintenance and replacement of City Safety components may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable. An active and aware driving style may therefore delay collision warnings and intervention in order to minimize unnecessary warnings.
