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.

NOTE
The light illuminates on the side of the vehiclewhere the system has detected the vehicle. Ifthe vehicle is passed on both sides simulta-neously, both lights come on.

WARNING
The BLIS function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
The responsibility for changing lanessafely and using good judgment alwaysrests with the driver.
BLIS is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle 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.

Ignition modes
The vehicle's ignition can be put in variousmodes (levels) to make different functions availa-ble.
To enable the use of a limited number of func-tions when the engine is not running, the ignitioncan be put in one of three different levels: 0, Iand II. These levels are referred to as "ignitionmodes" in the Owner's Manual.
The following table shows which functions areavailable in each ignition mode:
Mode Functions
0The odometer, clock and tem-
perature gauge are illuminatedA.
The power* seats can beadjusted.
The power windows can be used.
The center display is activated
and can be usedA.
The infotainment system can be
usedA.
In this mode, the functions are availa-ble for a limited time and then switchoff automatically.
IThe panoramic roof, power win-dows, 12-volt electrical socket inthe passenger compartment,Bluetooth, navigation, phone,blower and windshield wipers canbe used.
The power seats can be adjusted.
The 12-volt electrical socket* inthe trunk can be used.
Electrical current will be takenfrom the battery in this ignitionmode.
Mode Functions
IIThe headlights illuminate.
Warning/indicator lights illumi-nate for 5 seconds.
A number of other systems areactivated. However, seat and rearwindow heating can only be acti-vated when the engine is running.
This ignition mode uses a lot ofcurrent from the battery andshould be avoided whenever pos-sible!

WARNING
If the warning symbols for both brake faultand ABS fault are lit simultaneously, theremay be a fault in the brake system.
If the brake fluid reservoir level is normalwhen this occurs, drive carefully to thenearest workshop to have the brake sys-tem checked - an authorized Volvo work-shop is recommended.
If the brake fluid has fallen below the MINlevel in the brake fluid reservoir, the vehi-cle should not be driven until the brakefluid has been filled. The reason for thebrake fluid loss must be checked.

Brake Assist System
The brake enhancing system, Brake AssistSystem (BAS), helps increase braking force andthereby reduce braking distance.
The system monitors the driver's braking habitsand increases braking force when necessary.Braking force can be increased up to the point atwhich the ABS intervenes. The function is deacti-vated when pressure on the brake pedal isdecreased.

Hill Start Assist
The function for assisting when starting the vehi-cle on inclines, Hill Start Assist (HSA), helpsprevent the vehicle from rolling backward whenstarting on an uphill gradient. When backing upa hill, HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-holdbrake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.
