Deactivation of the Auto-hold brake function
In certain situations, auto-hold will be deacti- vated when the vehicle is at a standstill andthe function will go into standby mode. Thismeans that the brakes will be released and thevehicle could begin to roll. The driver mustactively apply the brakes to keep the vehiclestationary. This can occur if:
the driver depresses the brake pedal
the parking brake is applied
the gear selector is moved to the
P, N or R
positions
the driver puts the function in standby mode.
Auto Activate Parking BrakeIn certain situations, the parking brake will beapplied to keep the vehicle at a standstill. This occurs if the function is keeping the vehi- cle stationary using the brakes and:
the driver opens the door or unbuckleshis/her seat belt
the function has kept the vehicle at astandstill for more than approx. 5 minutes
the brakes overheat
the driver switches off the engine man-ually.

Drive mode for driver support The driver can choose different drive modes to determine how driver support shouldmaintain a time interval to the vehicle ahead.
Settings are made using the
DRIVE MODE
controls. Select one of the following:

Pure - Driver support will focus on provid-
ing good fuel economy, which will increase the time interval to the vehicleahead.

Hybrid - Driver support will focus on fol-
lowing the set time interval to the vehicle ahead as smoothly as possible.

Power - Driver support will focus on fol-
lowing the set time interval to the vehicle ahead more exactly, which could meanfaster acceleration and heavier braking.

Park Assist Camera *
Blind sectors
There are "blind" sectors between the cameras' fields of vision.
With Park Assist Camera's 360° view *
selected, objects/obstacles may not be detected if they are located in the "joints"where the edges of the individual cameraviews meet.
WARNING
Even if it seems as though only a fairly small section of the screen image isobstructed, this may mean that a relativelylarge sector is hidden and obstacles theremay not be detected until they are verynear the vehicle.
Defective camera
If a camera sector is dark and contains this symbol, thisindicates that the camera isnot functioning properly. See the following illustration for an example.
The vehicle's left-side camera is malfunctioning.
A dark camera sector may also be displayed in the following situations, but without the
defective camera symbol: a door is open
the trunk lid is open
a rearview mirror is folded in
Lighting conditions
The camera image is automatically adjusted according to the current lighting conditions.This means that the brightness and quality of the image may vary slightly. Poor lighting con-ditions may result in reduced image quality.
Rear Park Assist Camera
NOTE
A bike carrier and other accessories moun- ted on the rear of the vehicle can obscurethe camera's view.

Recommended camera and radar sensor maintenance
In order for the camera and radar sensor to function properly, they must be kept free ofdirt, ice, snow, etc. and should be washedregularly with water and car washing deter-gent.
NOTE
Dirt, ice and snow covering the sensors could cause false warnings, reduced func-tion, or no function.
Location of the Park Assist sensors.
Location of rear radar sensors. Keep the marked area clean (on both the left and right sides of the vehicle).
For best possible performance, it is impor- tant to keep the areas in front of the sen-sors clean.
Do not attach any objects, tape or decalsto the surface of the sensors.
Clean the camera lenses regularly usinglukewarm water and car washing deter-gent. Wash gently to avoid scratching thelens.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.

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 there-fore not intervene in situations in which yourvehicle is approaching another vehicle veryslowly, such as when 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 insituations in which the driver is clearly steeringand operating the accelerator pedal, even if acollision is unavoidable. An active and aware driving style may there- fore delay collision warnings and interventionin order to minimize unnecessary warnings.
Other limitations
WARNING
The driver support system only issues a warning for obstacles detected by its radarsensor – thus, a warning may come after adelay or not at all. Never wait for a warning or assistance. Apply the brakes when necessary.
WARNING
Warnings and brake interventions can be triggered late or not at all if the traf-fic situation or external influences pre-vent the camera and radar unit fromproperly detecting pedestrians,cyclists, large animals or vehiclesahead of the vehicle.
To be able to detect vehicles at night,its front and rear lights must work andilluminate clearly.
The camera and radar unit have a lim-ited range for pedestrians and cyclists– the system can provide effectivewarnings and brake interventions if therelative speed is lower than 50 km/h(30 mph). For stationary or slow-mov-ing vehicles, warnings and brake inter-ventions are effective at vehicle speedsof up to 70 km/h (43 mph). Speedreduction for large animals is less than15 km/h (9 mph) and can be achievedat vehicle speeds over 70 km/h(43 mph). At lower speeds, the warn-ing and brake intervention for large ani-mals is less effective.
Warnings for stationary or slow-mov-ing vehicles and large animals can bedisengaged due to darkness or poorvisibility.
Warnings and brake interventions for pedestrians and cyclists are disen-gaged at vehicle speeds over 80 km/h(50 mph).
Do not place, affix or mount anythingon the inside or outside of the wind-shield, or in front of or around the cam-era and radar unit – this could disruptcamera-based functions.
Objects, snow, ice or dirt in the area ofthe camera sensor can reduce thefunction, disengage it completely orgive an improper function response.

Cross Traffic Alert *67
Cross Traffic Alert(CTA) is a supplementary driver support system to BLIS 68
that is
intended to help the driver detect vehicles crossing behind the vehicle while backing up. The auto-brake subfunction can help the
driver stop the car if there is a risk of collision with an unobserved vehicle.
Examples of areas in which CTA can help the driver detect obstacles while backing up.
CTA supplements BLIS by detecting traffic crossing from the side, e.g. when backing outof a parking space. CTA is primarily designed to detect vehicles, but in certain cases can also detect pedes-trians or smaller 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 approaching your vehicle from the side:
an audible signal will sound from eitherthe left or right speaker, depending onwhich side of your vehicle the object isapproaching from.
an icon will illuminate in the
Park Assist
System graphic on the screen.
an icon will appear in the Park Assist Cam- era's Top view.
Illuminated CTA icon in the
Park Assist System
graphic on the screen.
If the driver does not pay attention to the warning from CTA and a collision is unavoida- ble, the
auto brake function will intervene to
stop the vehicle and a text will be shown onthe instrument panel to explain why the vehi-cle was braked.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.

limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in
certain situations. Auto-brake is active atspeeds under 15 km/h (9.3 mph).
WARNING
The auto-brake sub-function can only
detect and apply the brakes for other mov- ing vehicles – not for e.g. stationary obsta-
cles, cyclists or pedestrians.
CTA has certain limitations – The CTA sen- sors, for example, cannot "see" through otherparked vehicles or objects blocking the vehi-cle. Below are a few examples of situations in which CTA's field of vision may be initially lim-ited and approaching vehicles may thereforenot be detected until they are very close toyour vehicle:
69 Warning for crossing traffic when the vehicle is backing up.
70 Warning for crossing traffic when the vehicle is backing up.

Park Assist*
The Park Assist function can help the driver when maneuvering in tight spaces by indicat-ing distances to obstacles using audible sig-nals and graphics in the center display.
Display view showing obstacle zones and sensor sectors.
The center display shows an overview of the vehicle in relation to objects that have beendetected. The marked sector indicates where the obsta- cle is located. The closer the vehicle symbol isto a marked sector forward/rearward, thecloser the detected obstacle is to your vehicle. The side sectors change color as the distance between the vehicle and an object decreases. The audible signals will also speed up the closer the obstacle is to the vehicle. The vol- ume of the audio system will be automaticallylowered. Audible signals for obstacles in front and to the sides of the vehicle are active when thevehicle is moving but will cease after the vehi-cle has been stationary for approx. 2 seconds.Audible signals for obstacles behind the vehi-cle will remain active even when the vehicle isstationary. 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 an obstacle to the sides of the vehicle, anrapid pulsing signal will be given and theactive sector fields will change color fromORANGE to RED. The volume of the Park Assist audible signals can be adjusted while the signal is being givenusing the
>II knob or in the center display's
Top view under
Settings.
NOTE
Besides in the sector closest to the vehicle symbol, audible warnings are only providedfor objects located directly in the vehicle'spath.
