LIGHTING
156
Parking lights The parking lights can be used to help other road 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 to
turn on the parking lights (the license plate light- ing will also illuminate). Canadian models: If the ignition is in the II posi-
tion or the engine is running, the daytime running lights will illuminate instead of the front parkinglights. With the lighting ring in this position, theparking lights will remain on regardless of whatposition the ignition is in. US models: When
mode is selected, the
daytime running lights can be deactivated in the center 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 also illuminate when the tailgate is opened to alert fol-lowing 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-dimIf bright light enters the vehicle from behind, the door mirrors will automatically dim. Auto-dim isalways active when the engine is running, exceptwhen reverse gear is engaged.
NOTE
When the level of sensitivity is changed, this change will not be noticeable immediately butwill instead take effect after a short period oftime.
The sensitivity level for dimming will affect both the rearview mirror and door mirrors. 1. Tap
Settings in the Top view in the center
display.
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 eliminate glare. 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 parking permit, transponder, sunshade or objects onthe seats or in the cargo compartment in away that prevents light from reaching the sen-sors, the auto-dim function in the door andrearview mirrors 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 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.

Cross Traffic Alert *
CTA 86
is a supplementary driver support system
to BLIS 87
that is intended to help the driver
detect vehicles crossing behind the vehicle while 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, but in certain cases can also detect pedestrians orsmaller objects such as bicycles. CTA is only active when the vehicle is moving backward 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 PAS 88
graphic
on the screen.
• an icon will appear in the Park Assist Cam-era's Top view.

CTA 91
functionality may be reduced in certain
situations.
CTA does not function optimally in all situations and 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 which CTA'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 a parking 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 driver
when maneuvering in tight spaces by indicating distances 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 obstacle is located. The closer the vehicle symbol is to amarked sector, the closer the detected obstacleis to your vehicle. The audible signals will also speed up the closer the obstacle is to the vehicle. The volume of theaudio system will be automatically lowered. Audible signals for obstacles in front and to the sides of the vehicle are active when the vehicle is moving 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 30 cm (1 ft) from the front or rear of the vehicle, the tone willbecome constant and the active sensor's fieldclosest to the vehicle symbol will be filled in. The volume of the Park Assist audible signals can be adjusted while the signal is being given using the
>II knob or in the center display's Top
view under
Settings.
NOTE
• Acoustic warnings are only given for objects directly in front of the vehicle'spath.
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 depending on which part of the vehicle is approaching anobstacle.
Back
Note: This illustration is general and details may vary depending on model.
The rear sensors will be activated if the vehicle begins rolling backward or if reverse gear isengaged. The distance monitored begins approx. 1.5 meters (5 feet) behind the vehicle. The rear sensors will be automatically deactivated if the vehicle is backing up with a trailer attached.
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.
Side sensors
Park Assist's side sensors are automatically acti- vated when the engine is started. They are activeat speeds below 10 km/h (6 mph). The distance monitored begins approx. 30 cm (1 ft) from the sides. The audible signal for obsta-cles along the sides of the vehicle is emittedfrom the side speakers.
Front camera
Note: This illustration is general and details may vary depending on model.
Park Assist's front sensors are automatically acti- vated when the engine is started. The front sen-sors are active at speeds below 10 km/h(6 mph). The distance monitored begins approx. 80 cm (2.5 ft) in front of the vehicle.
NOTE
The Parking Assist system is deactivated when the parking brake is applied or when P
is selected on vehicles with automatic trans- mission.
