City Safety limitations
City Safety functionality may be reduced in cer-tain situations.

Surroundings
Low objects
Hanging objects, such as flags for overhangingloads 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 roadsmay reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con-
trol (ESC68) will help provide optimal brakingpower with maintained stability.

Backlighting
The visual warning signal in the windshield maybe 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 compartmentis 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 thanclean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all.
If a text message displayed in the instrumentpanel 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 Safetycomponents may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when thevehicle is backing up.

Low speed
City Safety is not activated at very low speedsunder 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. CitySafety 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 thereforedelay collision warnings and intervention in orderto minimize unnecessary warnings.

Other limitations
WARNING
Warnings and brake interventions can betriggered late or not at all if the traffic sit-uation or external influences prevent thecamera and radar unit from properlydetecting pedestrians, cyclists, large ani-mals or vehicles ahead of the vehicle.
To be able to detect vehicles at night, itsfront and rear lights must work and illumi-nate clearly.
The camera and radar unit have a limitedrange for pedestrians and cyclists – thesystem can provide effective warningsand brake interventions if the relativespeed is lower than 50 km/h (30 mph).For stationary or slow-moving vehicles,warnings and brake interventions areeffective at vehicle speeds of up to70 km/h (43 mph). Speed reduction forlarge animals is less than 15 km/h(9 mph) and can be achieved at vehiclespeeds over 70 km/h (43 mph). At lowerspeeds, the warning and brake interven-tion for large animals is less effective.
Warnings for stationary or slow-movingvehicles and large animals can be disen-gaged due to darkness or poor visibility.
Warnings and brake interventions forpedestrians and cyclists are disengagedat vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anything onthe inside or outside of the windshield, orin front of or around the camera andradar unit – this could disrupt camera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce the func-tion, disengage it completely or give animproper function response.

NOTE
The function uses the vehicle's combinedcamera and radar unit, which has certain gen-eral limitations; see sections "Camera limita-tions" and "Radar sensor limitations".

Market limitations
City Safety is not available in all countries. If CitySafety is not shown in the center display'sSettings menu, your vehicle is not equipped withthis function.

Rear Collision Warning
The Rear Collision Warning (RCW) function canhelp the driver avoid rear-end collisions fromvehicles approaching from behind.
RCW is automatically activated each time theengine is started.
RCW can warn the driver of a potential collisionwith vehicles approaching from behind by rapidlyflashing the turn signals.
If, at a speed below 30 km/h (20 mph), the RCWfunction detects that the car is in danger of beinghit from behind, the seatbelt tensioners may ten-sion the front seatbelts and activate the WhiplashProtection System safety system.
Immediately before a collision from behind, RCWmay also activate the foot brake in order toreduce the forward acceleration of the car duringthe collision. However, the brakes will only beapplied if your vehicle is stationary. The brakeswill be immediately released if the acceleratorpedal is depressed.

Whiplash Protection System (p. 46)
Rear Collision Warning limitations
In some situations, it may be difficult for RCW towarn the driver of a collision risk.
This may be the case if:
the vehicle approaching from the rear isdetected at a late stage
the vehicle approaching from the rearchanges lanes at a late stage
the vehicle approaching from the rear is mov-ing at a speed above 80 km/h (50 mph)
a trailer, bicycle holder or similar is con-nected to the vehicle's electrical system - theRCW function will then be automaticallydeactivated.
NOTE
In certain markets RCW does not warn withthe direction indicators due to local trafficregulations – in such cases, that part of thefunction is deactivated.

NOTE
The warning with direction indicators for RearCollision Warning is deactivated if the colli-sion warning distance in the City Safety func-tion is set to the lowest level "Late".
The seat belt tensioning and braking func-tions remain active.
