Function buttons and symbols
–Press the button (2).
> The
symbol in the instrument panel
will change colors from WHITE to GRAY and the set speed in the center of thespeedometer will change from BEIGE toGRAY.
Standby mode due to action by the driverACC is temporarily deactivated and put in standby mode if:
• the brakes are applied
• The gear selector is moved to
N
• the vehicle is driven faster than the set speed for more than 1 minute. In these cases, the driver will have to regulate the vehicle's speed. A temporary increase in speed, such as when passing another vehicle, does not affect the ACCset speed. The vehicle will return to the set speedwhen the accelerator pedal is released.
Automatic standby modeACC interacts with other systems, such as Electronic Stability Control. If any of these othersystems are not functioning properly, ACC willturn off automatically.
WARNING
If this happens, the driver will be alerted by an audible signal and a message in the instru-ment panel. The driver will have to adapt thevehicle's speed, apply the brakes when nec-essary and keep a safe distance to the vehicleahead.
ACC switches automatically to standby mode if: • the vehicle's speed goes below approx. 3 mph (5 km/h) and ACC cannot determineif the vehicle ahead is stationary or is anobject such as a speed bump, 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
• the driver opens the door
• the driver unbuckles the seat belt •
engine speed (rpm) is too high/low
• the wheels lose traction
• the parking brake is applied
• the stability system's
ESC Sport Mode is
activated
• the
Off Road drive mode is selected
• The radar sensor is covered by e.g., wet snow or if heavy rain interferes with radar waves
Reactivating ACC from standby modeTo reactivate ACC after it has temporarily been put in standby mode:
–Press the button (1).
> The vehicle will then return to the most
recently set speed .
WARNING
There may be a significant increase in speed after the
button has been pressed.

WARNING
•Pilot Assist is designed to be a supple- mentary driving aid and cannot cover alldriving situations, traffic, weather and/orroad conditions.
• The driver should be familiar with all ofthe information in this article regardingPilot Assist, including its limitations.
• Pilot Assist is not intended to replace thedriver's attention and judgement.
• Pilot Assist must only be used wherethere are clearly visible traffic lane sidemarker lines on both sides of the currenttraffic lane. In other circumstances thereis an increased risk of collision with sur-rounding obstacles that are not detectedby the system.
• The driver is always responsible for steer-ing the vehicle and maintaining a suitablespeed and distance to the vehicle aheadand must intervene if necessary, even ifPilot Assist is being used.
Pilot Assist is designed to regulate speed smoothly but in situations calling for fast braking,the driver must apply the brakes. This applies tosituations where there are considerable differen-ces in speed or if the vehicle ahead brakes sud-denly. Due to the limitations of the camera andradar sensor, the system may apply the brakes inyour vehicle suddenly or not at all. The default speed for Pilot Assist is preset toapprox. 30 mph (50 km/h) and cannot bechanged. If the vehicle ahead increases speed toover 30 mph (50 km/h) and pulls away from yourvehicle, Pilot Assist will go into standby mode.
NOTE
•
Pilot Assist maintenance should only be carried out by a trained and qualifiedVolvo service technician.
• Pilot Assist regulates your vehicle'sspeed using the accelerator pedal andthe brakes. Please be aware that theremay be a faint sound from the brakeswhen the system is using them.
WARNING
•Pilot Assist does not react to people or animals, or small vehicles such as bicy-cles and motorcycles. It also does notreact to low trailers, slow moving, parkedor approaching vehicles, or stationaryobjects.
• 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.

Starting and activating Pilot Assist
The Pilot Assist feature helps keep the vehicle in its current traffic lane, at a set speed and a settime interval to the vehicle ahead.
Function buttons and symbols
PrerequisitesThe prerequisites for activating Pilot Assist are:
• The vehicle ahead must be within a reasona- ble (detectable) distance
• The camera must be able to clearly detectthe traffic lane's side marker lines
• The vehicle's speed must be under approx.30 mph (50 km/h). A WHITE symbol indicates that Pilot Assist has been selected. In other cases, the WHITE arrow pointing to the right indi-cates that the system is availa-ble.
A YELLOW symbol with a flashing WHITE arrowindicates that the system is about to shift intostandby mode.
With ACC in standby mode: 1. Tap ▶ (4).
> The symbol will be displayed and Pilot Assist will go into standby mode.
2. Press the
button (1) on the left-side
steering wheel keypad.

• 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.

DRIVER SUPPORT
274When triggered, City Safety carries out three steps in the following order: 1.
Collision warning
2. Brake assistance
3. Auto-brake
1: Collision warningThe driver is first alerted to the risk of an immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary or that are moving inthe same direction as your vehicle. The driver isalerted by a flashing red warning signal, an audi-ble signal and pulsations in the brake pedal.
2: Brake assistanceIf the risk of a collision increases, brake supportwill be activated. This function increases pressure on the brake pedal if the driver does not apply enough pres-sure to the pedal.
3: Auto-brakeThe brakes will be applied automatically. If the driver has not taken action at this stage and a collision is imminent, auto-braking will be trig-gered. Full braking effect will be used to avoidthe collision if possible or to make the speed atthe point of impact as low as possible. In certain situations, auto-braking may begin with limited effect before full braking is used. If City Safety has prevented a collision, the vehi-cle will be kept at a standstill until the drivertakes action. If the vehicle has slowed to avoidcolliding with the vehicle ahead, your speed willbe reduced to that vehicle's speed. When auto-break is triggered, the seat belt pre- tensioners may also be activated, see the article"Seat belts" for additional information. Auto-braking can be cancelled if the driver presses hard on the accelerator pedal. When City Safety applies the brakes, the brake lights will illuminate. When City Safety is triggered and applies the brakes, a text message will be displayed in theinstrument panel.
WARNING
Warnings will only be provided if there is an imminent risk of a collision taking place. Thedriver should be aware of the system's limita-tions before operating the vehicle. Warnings for pedestrians and cyclists will not be provided if the vehicle's speed is above50 mph (80 km/h). City Safety's auto-brake function can help prevent a collision or reduce the speed atwhich a collision occurs. However, the drivershould always apply the brakes, even if auto-brake is operating. The driver is always responsible for maintain- ing the correct speed and distance in relationto the vehicle ahead. Never wait for a collisionwarning or for City Safety to intervene. City Safety maintenance may only be carried out by a trained and qualified Volvo servicetechnician.

City Safety warning level settingsCity 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 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. 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. 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.
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.

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,

276shoulders, legs, the upper and lower parts of the body 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 an "adult-size" bike.
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.
• carrying a large object.
The driver is always responsible for operating the vehicle in a safe manner.
