Activating and starting the Pilot Assist
*
Pilot Assist must first be activated and then started to be able to control speed and distanceand to give steering assistance.
NOTE: The illustration is schematic - details may vary depending on car model.
In order to start the Pilot Assist it is required that:
• The driver's seatbelt must be buckled and the driver's door must be closed.
• There must be a vehicle (the "target vehicle")within reasonable distance in front of the car,or the current speed must be at least15 km/h (9 mph).
• For cars with manual gearbox. Speed mustbe at the lowest 30 km/h (20 mph).

Automatic standby mode
Pilot Assist is dependent on other systems, e.g. stability control/anti-skid ESC. If any of theseother systems stops working, Pilot Assist isswitched off automatically. In the event of automatic deactivation a signal will sound and a message is shown in the driver dis-play. The driver must then intervene and adaptthe speed and distance to the vehicle ahead. Automatic deactivation may occur if:
• the speed is below 5 km/h (3 mph) and Pilot Assist is uncertain whether the vehicle aheadis a stationary vehicle or an object, such as aspeed bump.
• the speed is below 5 km/h (3 mph) and thevehicle ahead turns off so that Pilot Assist nolonger has a vehicle to follow.
• speed is reduced to below 30 km/h(20 mph) - only applies to cars with manualgearbox.
• the driver's hands are not on the steeringwheel
• the driver opens the door
• the driver takes off the seatbelt
• engine speed is too low/high
• wheels lose traction
• brake temperature is high
• the parking brake is applied •
the camera and radar unit is covered by e.g.snow or heavy rainfall (camera lens/radiowaves are blocked).
Reactivating Pilot Assist from the
standby mode
NOTE: The illustration is schematic - details may vary depending on car model.
–Press the steering wheel button (1).
> The speed is then set to the most recently stored speed.
NOTE
A marked speed increase may occur once the speed has been resumed by pressing steer- ing wheel button

IMPORTANT
In certain situations, Pilot Assist steering assistance may have difficulty helping thedriver in the right way or it may be automati-cally deactivated - in which case, the use ofPilot Assist is not recommended. Examples ofsuch situations may be that: •the lane markings are worn, missing or cross each other.
• lane division is unclear, for example, whenthe lanes divide or merge or at exits or inthe event of multiple sets of markings.
• edges or other lines than lane markingsare present on or near the road, e.g.curbs, joints or repairs to the road sur-face, edges of barriers, roadside edges orstrong shadows.
• the lane is narrow or winding.
• the lane contains ridges or holes.
• weather conditions are poor, e.g. rain,snow or fog or slush or impaired viewwith poor light conditions, back-lighting,wet road surface etc.
The driver should also note that Pilot Assisthas the following limitations: • High kerbs, roadside barriers, temporary obstacles (traffic cones, safety barriers,etc.) are not detected. Alternatively, theymay be detected incorrectly as lane
markings, with a subsequent risk of con- tact between the car and such obstacles.The driver must ensure him/herself thatthe car is at a suitable distance from suchobstacles.
• The camera and radar sensor does nothave the capacity to detect all oncomingobjects and obstacles in traffic environ-ments, e.g. potholes, stationary obstaclesor objects which completely or partiallyblock the route.
• Pilot Assist does not "see" pedestrians,animals, etc.
• The recommended steering input is forcelimited, which means that it cannotalways help the driver to steer and keepthe car within the lane.
The driver always has the possibility of correcting or adjusting a steering intervention imposed byPilot Assist and can turn the steering wheel tothe desired position.
Steep roads and/or heavy loadBear in mind that Pilot Assist is primarilyintended for use when driving on level road surfa-ces. The function may have difficulty in keepingthe correct distance from the vehicle ahead whendriving on steep downhill slopes - in which case,be extra attentive and ready to brake. Do not usePilot Assist with a heavy load or with a trailer con-nected to the car.
Miscellaneous
•Off Road drive mode cannot be selected
when Pilot Assist is activated.
NOTE
The function uses the car's camera unit, which has some general limitations, see the"Limitations for camera unit" section.
NOTE
The function uses the car's radar unit, which has some general limitations, see the "Limita-tions for radar unit" section.

The previous illustration 11
shows that Pilot Assist
is set to maintain 110 km/h and that there is no vehicle ahead to follow. Pilot Assist provides no steering assistance since the lane's side markings cannot be detected.
The previous illustration 11
shows that Pilot Assist
is set to maintain 110 km/h and at the same time follow the vehicle ahead that is keeping thesame speed. Pilot Assist provides no steering assistance since the lane's side markings cannot be detected.
10 In the following illustrative example, the RSI (Road Sign Information) function informs that the maximum permitted speed is 130 km/h.

CauseAction
Water or snow from the road surface swirls up and blocks the radar signals or camera view. No action. Sometimes the unit does not work on a very wet or snow-coveredroad surface.
Dirt has appeared between the inside of the windscreen and the cameraand radar unit. Visit a workshop to have the windscreen inside the unit's cover cleaned - anauthorised Volvo workshop is recommended.
NOTE
Keep the windscreen clean in front of the camera and radar unit.
Vehicle speedThe capacity of the radar unit to detect vehicles ahead is reduced significantly if:
• the speed of the vehicle ahead is signifi-cantly different from that of your own car
Limited field of visionThe radar unit has a limited field of vision. Insome situations another vehicle is not detected,or the detection is made later than expected.
The radar unit's field of vision.
Sometimes the radar unit is late at detecting vehicles at close distances - e.g. a vehicle that drives in between your car and the vehi-cle ahead.
Small vehicles, such as motorcycles, or vehi- cles not driving in the centre of the lane canremain undetected.
In bends, the radar unit may detect the wrong vehicle or lose a detected vehicle fromview.
Low trailers
Low trailer in radar shadow.
Low trailers can also be difficult for the radar unit to detect, or are not detected at all - the drivershould therefore be particularly careful when driv-ing behind low trailers when the adaptive cruisecontrol or Pilot Assist is activated.

WARNING
City Safety is an aid and does not work in all driving situations, traffic, weather and roadconditions. Warning only activated in the event of a high risk for collision. This section and the section"Limitations for City Safety" inform about limi-tations that the driver should be aware ofbefore using City Safety. Warnings and brake interventions for pedes- trians and cyclists are deactivated at vehiclespeeds above 70 km/h (43 mph). City Safety's auto-brake function can prevent a collision or reduce collision speed. Toensure full brake performance, the drivershould always depress the brake pedal - evenif the car auto-brakes. City Safety does not activates any auto-brake functions in the event of heavy acceleration. The driver is always responsible for maintain- ing the correct distance and speed - neverwait for a collision warning or for City Safetyto intervene.
Market limitationCity Safety is not available in all countries. If City Safety does not appear in the centre display's
Settings menu, the car is not equipped with this
function. Search path in the top menu:

Acoustic warning signal in the event of a risk of collision
Warning signal in the event of a risk of colli- sion
Distance measurement with the camera and radar unit
City Safety carries out three steps in the follow-ing order:
1. Collision warning
2. Brake support
3. Auto Brake
Collision warning
The driver is first warned of a potentially immi- nent collision. City Safety can detect pedestrians, cyclists or vehicles that are stationary or moving in the samedirection as the car and are ahead. City Safetycan also detect pedestrians, cyclists or large ani-mals that are crossing the road in front of the car. In the event of a risk of collision with a pedes- trian, large animal, cyclist or vehicle (includingvehicles described in the "City Safety in crosstraffic" section), the driver's attention is alerted bymeans of a red flashing warning signal, an acous-tic signal and a haptic warning in the form of abrake pulse. At lower speeds or with hard brakingor acceleration there will be no haptic warning.The brake pulse frequency varies according tothe car's speed.
Brake support
If the risk of collision has increased further after the collision warning then the brake support isactivated. Brake support reinforces the driver

334bicycle outline, requiring the ability to identify the bicycle, head, arms, shoulders, legs, upper andlower body plus a normal human pattern of move-ment. If large parts of the cyclist's body or bicycle are not visible to the function's camera then the sys-tem cannot detect a cyclist. For the function to be able to detect a cyclist, he/she must be an adult and riding a bicycledesigned for adults.
WARNING
City Safety is an aid, and cannot detect all cyclists in all situations and, for example, can-not see: •
partially obscured cyclists.
• cyclists wearing clothing that obscures the body outline.
• bicycles loaded with large objects.
The driver is always responsible that the vehi- cle is driven correctly and with a safety dis-tance adapted to the speed.
Pedestrians
Optimal examples of what the system regards as pedes- trians with clear body outlines.
For optimal performance, the system function that detects pedestrians must receive the clear-est possible information about the body outline,requiring the ability to identify the head, arms,shoulders, legs, upper and lower body plus a nor-mal human pattern of movement. In order that it shall be possible to detect a pedestrian there must be a contrast with thebackground and this will be affected by suchthings as clothes, the background and theweather. With poor contrast the pedestrian mayeither be detected late or not at all, which maymean that warnings and braking are late or omit-ted. City Safety can also detect pedestrians in thedark if they are illuminated by the car's head-lamps.
WARNING
City Safety is an aid and cannot detect all pedestrians in all situations and, for example,cannot see:
• partially obscured pedestrians, people in clothing that hides their body contour orpedestrians shorter than 80 cm.
• pedestrians if the background contrast ofthe pedestrians is poor - warning andbrake interventions may then be late ornot occur at all.
• pedestrians who are carrying largerobjects.
The driver is always responsible that the vehi-
cle is driven correctly and with a safety dis- tance adapted to the speed.

Large animals
Optimum examples of what City Safety interprets as large animals - standing still or walking slowly and withclear body outline.
Optimal performance requires that the system function that detects a large animal (e.g. elk andhorse) must receive the clearest possible infor-mation about the body outline, requiring the abil-ity to identify the animal directly from the side incombination with what is a normal pattern ofmovement for the animal. If parts of the animal's body are not visible to the function's camera then the system cannot detectthe animal. City Safety can also detect large animals in the dark if they are illuminated by the car's head-lamps.
WARNING
City Safety is an aid, and cannot detect all large animals in all situations and, for exam-ple, cannot see:
• partially obscured large animals.
• larger animals seen from the front or from behind.
• large animals that run or move quickly.
• large animals if the background contrastof the animals is poor - warning andbrake interventions may then be late ornot occur at all.
• small animals such as dogs and cats, forexample.
The driver is always responsible that the vehi- cle is driven correctly and with a safety dis-tance adapted to the speed.
