Time interval controls
Press to reduce the time interval to the vehi- cle ahead
Press to increase the time interval to the vehicle ahead
Distance indicator
In order to follow the vehicle ahead as smoothly as possible, Pilot Assist allows the time interval tovary considerably in certain situations. At lowspeeds, when the distance to the vehicle aheadis short, Pilot Assist increases the time intervalslightly.
• If Pilot Assist does not seem to react when it is put in active mode, this may be becausethe set time interval to the vehicle aheaddoes not allow an increase in speed.
• The higher the speed, the greater the dis-tance to the vehicle ahead for a given timeinterval.
WARNING
• Only use a time interval that is suitable in current traffic conditions.
• A short time interval gives the driver lim-ited reaction time if an unexpected situa-tion occurs in traffic.

Pilot Assist auto-hold brake function At certain speeds, Pilot Assist provides braking effect.
Stop-and-go drivingDuring brief stops in slow-moving traffic or att traffic lights where the vehicle is not stopped formore than 3 seconds, driving will resume auto-matically. If it takes more than 3 seconds for thevehicle ahead to begin moving again, Pilot Assistwill go into standby mode and the auto-holdbrake function will activate. The driver will then have to reactivate Pilot Assist as follows:
–•
Press the button
• Press the accelerator pedal
> Pilot Assist will resume following the vehi- cle ahead if it begins to move within approx. 6 seconds.
NOTE
• Pilot Assist can keep the vehicle station- ary for max. 5 minutes, after which theparking brake will be set and Pilot Assistwill go into standby mode.
• The parking brake must be releasedbefore Pilot Assist can be reactivated.

City Safety warning level settings
City Safety is always activated but the function's warning distance can be adjusted.
NOTE
City Safety cannot be turned off and activates automatically each time the engine/electricmotor is started.
Setting a warning level (distance)
The distance set for warnings determines the system's responsiveness and sets the distance atwhich visual, audible and tangible (haptic) warn-ings will be triggered. To do so:1. Tap
Settings in the center display's Top
view.
2. Tap
My CarIntelliSafeCity Safety.
3. Choose among
Earlier, Normal or Later.
Begin by choosing
Earlier. If too many warnings
are given, change to Normal.
If the driver feels that warnings are given too often, the warning level can be lowered. Thismeans that warnings will be provided later, result-ing in fewer warnings being given. The setting
Later should only used in exceptional
circumstances, e.g., for a more dynamic driving style.
WARNING
• No automatic system can be guaranteed to function 100% correctly in all situa-tions. For that reason, never test CitySafety by driving toward a person orobject. This could result in serious injuryor death.
• Even if the setting
Earlier has been
selected, warnings may be perceived as being given late, e.g., if the difference inspeed is great or if the vehicle aheadbrakes suddenly.
• City Safety can provide a warning for apotential collision but it can never shortenthe driver's reaction time.
• To help make City Safety as effective as possible, always using the setting
Earlieris recommended.
NOTE
•Due to local traffic regulations in certain markets, RCW will
not activate the rear
turn signals. That part of the function will be deactivated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section
"Setting a warning level (distance)" in the article "City Safety settings."
• If RCW detects a vehicle approachingfrom behind, the seat belt pretensioners

Detecting cyclists and pedestrians with City Safety
City Safety can detect vehicles, cyclists and pedestrians.
VehiclesCity Safety detects most types of vehicles that are either stationary, moving in the same direc-tion as your vehicle or approaching when you areabout to turn left. In order for City Safety to detect a vehicle in darkness, its headlights and taillights must be onand clearly visible.
Cyclists
Optimal example of what the system considers to be a cyclist: clear body/bike contours
To help function optimally, City Safety's function for cyclist detection needs clear informationabout the bike itself and the rider's head, arms, shoulders, legs, the upper and lower parts of thebody and a cyclist's normal pattern of movement.
• If major parts of the cyclist's body are not visible to the camera, the system cannotdetect the cyclist.
• The cyclist must be an adult riding a bikeintended for an adult.
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect:
• all cyclists in all situations, e.g., a partially obscured cyclist will not be detected.
• a cyclist whose clothing prevents a clearview of the person's body contours.
• a cyclist transporting a large object.
The driver is always responsible for operating the vehicle in a safe manner.

Pedestrians
Optimal example of what the system considers to be a pedestrian: clear body contours
To help function optimally, City Safety's function for pedestrian detection needs clear informationabout the person's head, arms, shoulders, legs,the upper and lower parts of the body and a per-son's normal pattern of movement. In order to detect a pedestrian, there must be a contrast to the background. If there is little con-trast, the person may be detected late or not atall, which may result in a late or no reaction fromthe system. City Safety can also detect pedestrians in dark- ness with the help of the vehicle's headlights.•
If major parts of the pedestrian's body are not visible to the camera, he/she may not bedetected.
• In order to detect a pedestrian, the systemmust have a full view of the person's entirebody and the person must be at least 32 in.(80 cm) tall.
WARNING
City Safety is designed to be a supplementary driving aid. It cannot detect pedestrians:
• who are partially obscured, wearing cloth- ing that prevents a clear view of the per-son's body contours or who are not atleast 32 in. (80 cm) tall.
• who have limited contrast to their immedi-ate background. A warning or brakingmay be delayed or not come at all.
• carrying a large object.
The driver is always responsible for operating
the vehicle in a safe manner.

City Safety in crossing traffic
City Safety can help the driver when making a left turn in an intersection.
Turning at an intersection
1. The area in which City Safety can detect an oncoming vehicle
In order for City Safety to detect an approaching vehicle in situations where there is a risk of a col-lision, that vehicle must be within City Safety'srange (the red area in the illustration). The following criteria must also be met:
• your vehicle's speed must be at least 3 mph (4 km/h)
• the approaching vehicle's headlights must beon

City Safety limitations
City Safety ™ may have limited or reduced func-
tionality in certain situations.
The function has several limitations that the driver should be familiar with:
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's func-tion.
Slippery driving conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In situations of this type, the ABSbrakes and Electronic Stability Control will helpprovide braking power and stability.
Backlighting
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is notlooking straight ahead may make the visual warn-ing signal in the windshield difficult to see.
Heat
If the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically. The visual warning signal may also be temporarilydisabled due to high passenger compartmenttemperatures caused by strong sunlight. Warnings may not be given if the distance to the vehicle ahead is short and the driver is activelyoperating the vehicle (clearly depressing a pedalor turning the steering wheel).
Reduced visibility
City Safety's functions may be greatly impeded or deactivated by e.g., intense snowfall or rain, indense fog, in very dusty conditions or if there isblowing snow in front of the vehicle. Condensa-tion, ice, snow or dirt on the windshield may alsoreduce the system's functionality.
NOTE
•
Keep the windshield in front of the radar sensor free of ice, snow, dirt, etc.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sensor.Keep the hood free of ice and snow.
• Do not mount or in any way attach any-thing on the windshield that couldobstruct the radar sensor.

Camera and radar sensor's field of vision
The camera and radar sensor have limited fields of vision. In some situations they may detect avehicle, pedestrian or cyclist later than expectedor not detect them at all. Other vehicles that are dirty may be detected later than others and in dark conditions, motorcy-cles may be detected late or not at all. If a text message is displayed in the instrument panel indicates that the camera or radar sensorare blocked, it may be difficult for City Safety todetect a vehicle, pedestrian or cyclist and thesystem's functionality may be reduced.
WARNING
Text messages may not be displayed in all sit- uations in which the camera and/or radarsensor are blocked. It is therefore essential tokeep the windshield in front the camera/radarsensor clean and free from snow, ice, etc.
Camera and radar sensor components should only be serviced or replaced by a trained andqualified Volvo service technician.
Other limitations
City Safety uses the vehicle's camera and radar sensor, which have certain general limitations.See the articles "Camera limitations" and Radarsensor limitations" for additional information.
WARNING
• Warnings and braking may be delayed or not occur at all if traffic, weather or otherconditions prevent the camera and/orradar sensor from detecting pedestrians,cyclists or other vehicles correctly.
• Other vehicles can only be detected indarkness if their headlights and taillightsare clearly visible.
• The sensors have a limited range forpedestrians and cyclists. The systemfunctions best at speeds up to 30 mph(50 km/h). For stationary or slow-movingvehicles, the system functions best atspeeds up to approx. 43 mph (70 km/h).
• Warnings for stationary or slow-movingvehicles may be impeded by darkness orpoor visibility.
• Warnings and braking for pedestrians andcyclists will not be provided at speedsabove approx. 50 mph (80 km/h).
• Do not place, attach or mount any objectson the inside or outside of the windshieldnear or over the sensor. This could affectthe camera-based functions.
Action by the driver
Backing up
City Safety is temporarily deactivated while the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds (under approx. 3 mph (4 km/h). This means thatthe system will not be triggered if your vehicleapproaches a vehicle ahead, such as when park-ing.
Active driver
Action by the driver always has priority. For this reason, City Safety may not react or react laterthan expected in situations in which the driver isactively operating the vehicle, even if a collision isimminent. This is also done to help eliminateexcessive warnings.

The tone becomes constant when you are within approximately 1 ft (30 cm) of an object and theinnermost sensor field will be red. If there areobjects within this distance both behind and infront of the vehicle, the tone alternates betweenfront and rear speakers. While an audible signal is being given, its volume level can be raised/lowered using the
>II control
in the center console or can be adjusted in the Setting menu.
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to bea supplementary aid when parking the vehicle.It is not, however, intended to replace the driv-er's attention and judgement.
Rear park assist
The system's rear sensors are activated automat- ically when the engine is started and are active ifthe vehicle rolls rearward with the gear selector in N or if R has been selected.
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The rear sensors will be deactivated automatically when towing a trailer if Volvo genuine trailer wir-ing is used. If a non-Volvo trailer hitch is beingused, it may be necessary to switch off the sys-tem manually.
Side park assist
The system's side sensors are activated automat- ically when the engine is started and are active atspeeds below approximately 6 mph (10 km/h). The distance monitored along the sides of thevehicle is approximately 1 ft (0.3 m). The audiblesignal comes from the side speakers.
Front park assist
The system's front sensors are activated auto- matically when the engine is started and areactive at speeds below approximately 6 mph(10 km/h). The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signalcomes from the front speakers. Front Park Assist is deactivated if the parking brake is applied or if the gear selector is put in
P.
When installing auxiliary headlights, be sure that they do not obstruct the front sensors. Otherwise,these lights could trigger a Park Assist warning.

Overview
Blind Spot Information indicators
Indicator light
Blind Spot Information symbol
The indicator light illuminates on the side of the vehicle where the system has detected anothervehicle. If your vehicle is passed on both sides atthe same time, both lights will illuminate.
Principle for Blind Spot Information: Zone 1. Blind area, Zone 2. Area for approaching/passing vehicles
Blind Spot Information functions when your vehi- cle is moving at speeds above approx. 6 mph(10 km/h). Blind Spot Information is designed to react to:
• vehicles that are passing your vehicle
• other vehicles that are rapidly approaching your vehicle
When Blind Spot Information detects a vehicle in zone 1 or a fast-approaching vehicle in zone 2,the indicator light in the respective door mirrorwill glow steadily. If the driver then uses the turn signal on the side on which the warning is given, the indicator lightwill begin flashing and become brighter.
WARNING
• Blind Spot Information does not function in sharp curves.
• Blind Spot Information does not functionwhen your vehicle is backing up.

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control
