–The driver will then have to reactivate PilotAssist in one of the following ways:
•Press the button on the left-sidesteering wheel keypad
•Press the accelerator pedal
>Pilot Assist will resume following the vehi-cle ahead (target vehicle) if it begins tomove within approx. 6 seconds.
NOTE
Pilot Assist can keep the vehicle at a stand-still for up to 5 minutes, after which the park-ing brake will be set and Pilot Assist will gointo standby mode.
The parking brake has to be released beforePilot Assist can be reactivated.
Deactivation of the auto-hold brake function
In certain situations, auto-hold will be deactivatedwhen the vehicle is at a standstill and Pilot Assistwill go into standby mode.
This means that the brakes will be released andthe vehicle can begin to roll.
The driver must actively apply the brakes to keepthe vehicle at a standstill.
This can occur in the following situations:
•the driver presses the brake pedal
•the parking brake is set
•the gear selector is moved to the P, N or Rpositions
•the driver puts Pilot Assist in standby mode
Automatically setting the parking brake
In certain situations, the parking brake is setautomatically to help keep the vehicle at a stand-still.
This occurs if Pilot Assist keeps the vehicle at astandstill with the brakes and:
•the driver unbuckles the seat belt or opensthe door
•Pilot Assist has kept the vehicle at a stand-still for more than approx. 5 minutes
•the engine is turned off
•the brakes overheat

WARNING
Pilot Assist is not a collision avoidance sys-tem. The driver is always responsible forsteering or applying the brakes if the systemdoes not detect another vehicle.
Do not use Pilot Assist in demanding drivingconditions such as city driving or other heavytraffic situations, in slippery conditions, whenthere is a great deal of water or slush on theroad, during heavy rain or snow, in poor visibil-ity, on winding roads or on highway on- or off-ramps.
In certain situations, it may be difficult for PilotAssist to assist the driver correctly or to deac-tivate automatically. In such cases, it is advisa-ble not to use Pilot Assist. Examples of suchsituations may be:
•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.
•there are edges or other lines on or nearthe lane, e.g., curbs, cracks, repairedareas, sharp shadows, etc.
•the lane is narrow or winding.
•the lane is at the top of a hill, on anuneven road surface or over a bump.
•bad weather conditions (rain, snow, fog,slush, poor visibility, backlighting, etc).
The driver should also be aware that PilotAssist 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 PilotAssist.
Steep roads and/or heavy loads
Pilot 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. Thedriver should be attentive and prepared to applythe brakes in these situations.
Do not use Pilot Assist when the vehicle is trans-porting a heavy load or if it is towing a trailer.
Additional information
•The Off Road drive mode cannot beselected if Pilot Assist is activated.
•Pilot Assist uses the vehicle's camera andradar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

Radar sensor limitations
The radar sensor used by several of the driversupport systems has certain limitations, whichalso affect the systems using it.
Obstructions
The marked area must not be obstructed in any way.This area of the windshield should always be kept clean
The radar sensor is located at the upper, centersection of the windshield along with the camera.
WARNING
Never place any objects, decals, electronic tolldevices, window tinting films etc., on the wind-shield in front of or around the camera/radarsensor. This could reduce or block these com-ponents' functions, and could cause one ormore of the systems that utilize them to stopfunctioning.
This can also result in certain functions beingreduced or disabled, or they may respondincorrectly.
If this symbol and the messageWindscreen Sensors blockedappear in the instrument panel, thisindicates that the camera and/or radarsensor cannot detect other vehicles ahead.
The following table shows some of the situationsthat can cause the message to be displayed andsuggested actions.
CauseAction
The area of the windshield in front of the camera/radar sensor is dirty or covered by iceor snow.Clean the windshield or remove the ice/ snow.
Thick fog or heavy rain/snow reduces the camera/radar sensor's range of visibility.No action. The driver should be extra alert in conditions of thistype.
Water or snow on the surface of the road swirl up and block radar signals or the camera'sview.No action. The driver should be extra alert in conditions of thistype.
There is dirt between the inside of the windshield and the camera/radar sensor.Have the area of the windshield cleaned by a trained and quali-fied Volvo service technician.

WARNING
Warnings will only be provided if there is animminent risk of a collision taking place. Thedriver should be aware of the system's limita-tions before operating the vehicle.
Warnings and automatic braking for pedes-trians and cyclists are deactivated at speedsabove approx. 43 mph (70 km/h).
City Safety's auto-brake function can helpprevent 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 does not activate the auto-brakefunction during fast acceleration.
City Safety maintenance may only be carriedout by a trained and qualified Volvo servicetechnician.
Function overview
Audio-visual collision warning
Distance monitoring by a camera and radarsensor
When triggered, City Safety carries out threesteps in the following order:
1.Collision warning
2.Brake assistance
3.Auto-brake
1: Collision warning
The driver is first alerted to the risk of an immi-nent collision.
City Safety can detect pedestrians, cyclists orvehicles that are stationary, are moving in thesame direction as your vehicle or are in your vehi-cle's path.
City Safety can also detect pedestrians, large ani-mals or cyclists that are crossing in front of yourvehicle.
If there is a risk of a collision with a pedestrian,cyclist, large animal or a vehicle, as well as vehi-cles described in the article "City Safety in cross-ing traffic," the driver will be alerted by a flashingred warning signal, an audible signal and a hapticwarning in the form of pulsations in the brakepedal. At lower speeds, during hard braking or ifthe accelerator pedal is pressed, the haptic warn-ing will not be given.
2: Brake assistance
If the risk of a collision increases, brake supportwill be activated.
This function increases pressure on the brakepedal if the driver does not apply enough pres-sure to the pedal.
3: Auto-brake
The brakes will be applied automatically.
If the driver has not taken action at this stage anda 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 withlimited effect before full braking is used.
If City Safety has prevented a collision, the vehi-cle will be kept at a standstill until the driver
