Warning light
Pilot Assist can exert brake force that is equiva- lent to approximately 40% of the vehicle's totalbraking capacity. In situations requiring more brake force than Pilot Assist can provide and if the driver does notapply the brakes, an audible signal from the CitySafety system will sound and warning light willilluminate in the windshield to alert the driver toreact.
Head-up-display*
A flashing symbol alerts the driver
If the vehicle is equipped with a head-up display *,
a flashing symbol in the windshield will alert the driver.
NOTE
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver isnot looking straight ahead may make the vis-ual warning signal in the windshield difficult tosee.

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.

WARNING
•Pilot Assist is not a collision avoidance system. The driver is always responsiblefor applying the brakes if the system doesnot detect another vehicle.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in slipperyconditions, when there is a great deal ofwater or slush on the road, during heavyrain or snow, in poor visibility, on windingroads or on highway on- or off-ramps.
• Pilot Assist uses the vehicle's cameraand radar sensor, which have limitations.
Pilot Assist may deactivate or not function optimally if:
• the lane's side market lines are missing, badly faded or cross each other.
• the division of lanes is not clear, e.g.,when a line divides or merges withanother, at exits or if there are many roadsigns/markers.
• if there are edges or other lines on ornear the lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
• the lane is narrow or winding.
• the weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that Pilot Assist has the following limitations:
• High curbs, barriers and temporary obsta- cles (cones, barriers etc) may not bedetected or could be detected incorrectlyas side marker lines, which may create arisk of collision. The driver must ensure asafe distance to these obstacles.
• The camera or radar sensor may not beable to detect objects if there are pot-holes or if there are stationary objectspartially or completely blocking the road.
• Pilot Assist does not "see" pedestrians,animals, etc.
• Pilot Assist's steering capacity is limitedand may not always be able to help thedriver keep the vehicle in the lane.
The driver can always take action to override Pilot Assist.
Steep roads and/or heavy loadsPilot Assist is primarily intended for use on rela-tively level roads. The function may not be able tomaintain the correct time interval to the vehicleahead on when driving down steep hills, when thevehicle is transporting a heavy load or if it is tow-ing a trailer. The driver should be attentive andprepared to apply the brakes in these situations.

Other Adaptive Cruise Control (ACC) functions
ACC has several supplementary functions:
• Changing target vehicles
• Automatic standby mode when changing tar- gets
• Auto-hold brake function
• Deactivation of the auto-hold brake function
• Automatically setting the parking brake
Changing target vehicles
If the target vehicle turns suddenly, there may be a sta- tionary vehicle ahead
When ACC is actively following another vehicle at speeds
under 20 mph (30 km/h) and changes
targets from a moving vehicle to a stationary one, the system will brake for the stationary vehicle.
WARNING
If ACC changes targets from a moving vehicle to a stationary one at speeds above 20 mph
(30 km/h), the system will not react to the
stationary vehicle and will accelerate to the previously set speed. The driver must actively apply the brakes to slow/stop the vehicle.
Automatic standby mode when changing targets
ACC disengages and goes into standby mode if:
• your vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determine ifthe target object is a stationary vehicle orsome other type of object such as a speedbump, etc
• the vehicle's speed goes below approx.3 mph (5 km/h) and the vehicle aheadchanges lanes or turns so that ACC nolonger has a target vehicle to follow
Auto-hold brake functionIn slow-moving, stop-and-go traffic or when stop- ped at a traffic light, driving will resume automati-cally if the vehicle is not stopped for more thanapprox. 3 seconds. If it takes more than3 seconds for the vehicle ahead to begin movingagain, ACC will go into standby mode and theauto-hold brake function will activate.
–The driver will then have to reactivate ACC in one of the following ways:
• Press the
button on the left-side
steering wheel keypad
• Press the accelerator pedal
> ACC will resume following the vehicle ahead (target vehicle) if it begins to move
within approx. 6 seconds.
NOTE
ACC can keep the vehicle at a standstill for up to 5 minutes, after which the parking brakewill be set and ACC will go into standbymode. The parking brake has to be released before ACC 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.
