Parking lights
The parking lights can be used to help otherroad users see the vehicle if it is stopped orparked. Use the lighting ring on the steeringwheel lever to turn on the parking lights.
Lighting ring in the parking light position.
Turn the lighting ring to the position toturn on the parking lights (the license plate light-ing will also illuminate).
Canadian models: If the ignition is in the II posi-tion, the daytime running lights will illuminateinstead of the front parking lights. With the light-ing ring in this position, the parking lights willremain on regardless of what position the ignitionis in.
US models: When mode is selected, thedaytime running lights can be deactivated in thecenter display. The parking lights will also be
deactivated. In weak daylight or dark conditions,the parking lights and low beams will be illumi-nated.
In dark conditions, the rear parking lights alsoilluminate when the trunk lid is opened to alertfollowing traffic. This happens regardless of whatposition the lighting ring or ignition is in.

Adjusting the rearview mirrordimming function
Bright light entering the vehicle from behind, e.g.from the headlights of following vehicles, couldreflect in the rearview mirror and door mirrorsand cause a glare. Use the dimming functionwhen light from behind is distracting.

Auto-dim
If bright light enters the vehicle from behind, thedoor mirrors will automatically dim. Auto-dim isalways active when the engine is running, exceptwhen reverse gear is engaged.

NOTE
Adjustments to the sensitivity level will not benoticeable immediately but will instead takeeffect after a short period of time.
The sensitivity level for dimming will affect boththe rearview mirror and door mirrors.
To change the dimming sensitivity level:
1.Tap Settings in the Top view in the centerdisplay.
2.Tap My CarMirrors and Convenience.
3.Under Rearview Mirror Auto Dimming,select Normal, Dark or Light.
The rearview mirror instead has two sensors -one pointing forward and one pointing rearward -
which work together to identify and eliminateglare. The forward-pointing sensor monitorsambient light, while the rearward-pointing sensormonitors light from the headlights of followingvehicles.
For the door mirrors to be equipped with auto-dim, the rearview mirror must also be equippedwith auto-dim.
NOTE
If the sensors are obstructed by e.g. a parkingpermit, transponder, sunshade or objects onthe seats or parcel shelf in a way that pre-vents light from reaching the sensors, theauto-dim function in the rearview and doormirrors will be reduced.

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.

Cross Traffic Alert*
CTA77 is a supplementary driver support system
to BLIS78 that is intended to help the driverdetect vehicles crossing behind the vehiclewhile backing up.
CTA overview.
CTA supplements BLIS by detecting traffic cross-ing from the side, e.g. when backing out of aparking space.
CTA is primarily designed to detect vehicles, butin certain cases can also detect pedestrians orsmaller objects such as bicycles.
CTA is only active when the vehicle is movingbackward or if reverse gear is engaged.
If CTA detects that something is approachingyour vehicle from the side:
an audible signal will sound from either theleft or right speaker, depending on whichside of your vehicle the object is approachingfrom.
an icon will illuminate in the PAS79 graphicon the screen.
an icon will appear in the Park Assist Cam-era's Top view.
Illuminated CTA icon in the PAS graphic80 on thescreen.

WARNING
The Cross Traffic Alert function is supple-mentary driver support intended to facili-tate driving and make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
The responsibility for reversing the vehiclesafely and using good judgment alwaysrests with the driver.
Cross Traffic Alert is not a substitute forthe driver's attention and judgment. Thedriver is always responsible for ensuringthe vehicle is driven in a safe manner, atthe appropriate speed, with an appropri-ate distance to other vehicles, and inaccordance with current traffic rules andregulations.

Cross Traffic Alert limitations
CTA82 functionality may be reduced in certainsituations.
CTA does not function optimally in all situationsand has certain limitations. The CTA sensors, forexample, cannot "see" through other parkedvehicles or objects blocking the vehicle.
Below are a few examples of situations in whichCTA's field of vision may be initially limited andapproaching vehicles may therefore not bedetected until they are very close to your vehicle:
The vehicle is parked very far into a parking space.
In a diagonal parking space, CTA may be completely"blind" on one side of your vehicle.

However, as you back your vehicle slowly out of aparking space, CTA's field of vision changes inrelation to the obstructing vehicle/object and itsblind zone is reduced.

Park Assist*
The Park Assist function can help the driverwhen maneuvering in tight spaces by indicatingdistances to obstacles using audible signals andgraphics in the center display.
Display view showing obstacle zones and sensor sec-tors.
The center display shows an overview of the vehi-cle in relation to objects that have been detected.
The marked sector indicates where the obstacleis located. The closer the vehicle symbol is to amarked sector forward/rearward, the closer thedetected obstacle is to your vehicle.
The side sectors change color as the distancebetween the vehicle and an object decreases.
The audible signals will also speed up the closerthe obstacle is to the vehicle. The volume of theaudio system will be automatically lowered.
Audible signals for obstacles in front and to thesides of the vehicle are active when the vehicle ismoving but will cease after the vehicle has beenstationary for approx. 2 seconds. Audible signalsfor obstacles behind the vehicle will remain activeeven when the vehicle is stationary.
If a detected obstacle is within approx. 30 cm(1 ft) from the front or rear of the vehicle, thetone will become constant and the active sen-sor's field closest to the vehicle symbol will befilled in.
At distances within approx. 25 cm (0.8 ft) from anobstacle to the sides of the vehicle, an rapid puls-ing signal will be given and the active sectorfields will change color from ORANGE to RED.
The volume of the Park Assist audible signalscan be adjusted while the signal is being givenusing the >II knob or in the center display's Topview under Settings.

NOTE
Besides in the sector closest to the vehi-cle symbol, audible warnings are only pro-vided for objects located directly in thevehicle's path.
WARNING
The Parking Assist function is supple-mentary driver support intended to facili-tate driving and help make it safer – itcannot handle all situations in all traffic,weather and road conditions.
The parking sensors have dead/blindspots where objects cannot be detected.
Pay particular attention to people andanimals near the vehicle.
Parking Assist is not a substitute for thedriver's attention and judgment. The driveris always responsible for ensuring thevehicle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.

Park Assist front, rear and sides
Park Assist has different parameters dependingon which part of the vehicle is approaching anobstacle.

Front camera
Continuous tone warning signal when the obstacle isless than approx. 30 cm (1 ft) from the vehicle 107.
Park Assist's front sensors are automatically acti-vated when the engine is started. They are activeat speeds below 10 km/h (6 mph).
The distance monitored extends approx. 80 cm(2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivatedwhen the parking brake is applied or when Pis selected on vehicles with automatic trans-mission.

CAUTION
When installing auxiliary lights: Make surethese do not obscure the sensors – the auxili-ary lights could be perceived as an obstacle.

Back
Continuous tone warning signal when the obstacle isless than approx. 30 cm (1 ft) from the vehicle 107
The rear sensors will be activated if the vehiclebegins rolling backward or if reverse gear isengaged.
The distance monitored extendsapprox. 1.5 meters (5 ft) behind the vehicle.
The Parking Assist system's rear sensors will beautomatically deactivated if the vehicle is backingup with a trailer connected to the vehicle's elec-trical system.
NOTE
When reversing with e.g. a trailer or bike car-rier on the trailer hitch – without Volvo originaltrailer cables – the Parking Assist system mayhave to be turned off manually to prevent thesensors from reacting to these.

Park Assist limitations
Park Assist may not be able to detect all condi-tions in all situations and functionality may there-fore be limited in certain cases.
The driver should be aware of the following limi-tations for Park Assist:

WARNING
Be extra cautious whenreversing if this symbol isshown when a trailer, bikecarrier or similar is attachedand electrically connectedto the vehicle.
The symbol indicates thatthe rear parking assist sensors are deacti-vated and will not warn of any obstacles.
CAUTION
Objects such as chains, thin and glossy polesor low obstacles may end up in the "signalshadow" and then go temporarily undetectedby the sensors – the pulsating tone may thenunexpectedly stop instead of becoming aconstant tone as expected.
The sensors cannot detect high objects, suchas protruding ramps.
In such situations, pay extra attention andmaneuver/drive the vehicle very slowly orstop the current parking maneuver –there may be a high risk of damage tothe vehicle or other objects since infor-mation from the sensors is not alwaysreliable in such situations.

CAUTION
In some circumstances, the Park Assist Sys-tem may produce false warnings due to exter-nal sound sources with the same ultrasonicfrequencies as those the system works with.
Examples of such sources are horns, wet tireson asphalt, pneumatic brakes, exhaust noisefrom motorcycles, etc.
NOTE
When a trailer hitch is configured with thevehicle electrical system, the trailer hitch pro-trusion is included when the function meas-ures the distance to objects behind the vehi-cle.
