* (p. 280)
Distance Alert limitations36
Distance Alert functionality may be reduced in certain situations.WARNING
• The radar sensor has a limited field of vision. In some situations, it may detect avehicle later than expected or not detectother vehicles at all.
• The radar sensor cannot cover all drivingsituations and traffic, weather and roadconditions.
• The driver is responsible for maintaining asafe distance and speed and must inter-vene if the various driver support systemsdo not maintain a suitable speed or suita-ble distance to the vehicle ahead.
• Maintenance of radar sensor componentsmay only be performed by a trained andqualified Volvo technician.
• Strong sunlight, reflections from the roadsurface, strong lighting contrasts or usingsunglasses may make the warning light inthe windshield difficult to see. Poorweather or winding roads can affect theradar sensor's capacity to detect vehiclesahead.
• A vehicle's size (e.g., a motorcycle) canalso affect the radar sensor's capacity todetect another vehicle. This may result inthe warning light illuminating at a shorter

Adaptive Cruise Control regulates speed by accelerating and braking. It is normal for thebrakes to emit a slight sound when they arebeing used to adjust speed. Adaptive Cruise Control always attempts to regu- late speed smoothly. The driver must apply thebrakes in situations requiring immediate braking.For example, when there are great differences inspeed between vehicles or if the vehicle aheadbrakes suddenly. Due to limitations in the radarsensor, braking may occur unexpectedly or not atall. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintain atime interval to that vehicle set by the driver. If theradar sensor does not detect a vehicle ahead, itwill instead maintain the speed set by the driver.This will also happen if the speed of the vehicleahead exceeds the set speed for your vehicle.
• Adaptive Cruise Control can follow anothervehicle at speeds from a standstill up to200 km/h (125 mph).
WARNING
• Adaptive Cruise Control is not a collision avoidance system. The driver is alwaysresponsible and must intervene if the sys-tem fails to detect a vehicle ahead.
• Adaptive Cruise Control does not brakefor people or animals and does not brakefor small vehicles, such as bikes andmotorcycles. Similarly, it does not brakefor low trailers, oncoming, slow-moving orstationary vehicles and objects.
• Do not use Adaptive Cruise Control indemanding situations, such as in city traf-fic, at intersections, on slippery surfaces,with a lot of water or slush on the road, inheavy rain/snow, in poor visibility, onwinding roads, or on on/off ramps.
CAUTION
Maintenance of Adaptive Cruise Control com- ponents may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.

WARNING
•The Pilot Assist function is supplementary driver support intended to facilitate driv-ing and help make it safer – it cannothandle all situations in all traffic, weatherand road conditions.
• The driver is advised to read all sectionsin the Owner's Manual about this functionto learn of its limitations, which the drivermust be aware of before using the func-tion (see the link list at the end of thisarticle).
• Pilot Assist should only be used if thereare clear lane lines painted on each sideof the lane. All other use will increase therisk of contact with nearby obstacles thatcannot be detected by the functions.
• Pilot Assist is not a substitute for the driv-er's attention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theproper position within the lane, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
NOTE
Depending on market, this function may be either Standard or Optional.
Pilot Assist regulates speed by accelerating and braking. It is normal for the brakes to emit a slightsound when they are being used to adjust speed. Pilot Assist attempts to smoothly regulate speed. The driver must apply the brakes in situationsrequiring immediate braking. For example, whenthere are great differences in speed betweenvehicles or if the vehicle ahead brakes suddenly.Due to limitations in the camera and radar sen-sor, braking may occur unexpectedly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same lane and maintain a time interval tothat vehicle set by the driver. If the radar sensordoes not detect a vehicle ahead, it will insteadmaintain the speed set by the driver. This will alsohappen if the speed of the vehicle aheadexceeds the set speed for your vehicle.
• Pilot Assist can follow another vehicle atspeeds from a standstill up to 200 km/h(125 mph).
• Pilot Assist can provide steering assistancefrom near-stationary speeds up to 140 km/h(87 mph).
WARNING
• Pilot Assist is not a collision avoidance system. The driver must intervene if thesystem fails to detect a vehicle ahead.
• Pilot Assist does not brake for people,animals, objects, small vehicles (e.g.cycles and motorcycles), low trailers aswell as oncoming, slow or stationary vehi-cles.
• Do not use Pilot Assist in demanding sit-uations, such as in city traffic, at intersec-tions, on slippery surfaces, with a lot ofwater or slush on the road, in heavy rain/snow, in poor visibility, on winding roads,on highway on- or off-ramps, or with atrailer connected to the vehicle.
CAUTION
Maintenance of the integrated components in Pilot Assist may only be performed by a work-shop – an authorized Volvo workshop is rec-ommended.
In curves and forks in the roadPilot Assist is designed to interact with the driver. The driver should never wait for steering assis-tance from Pilot Assist, but instead should alwaysbe ready to increase his or her own steeringefforts, particularly in curves.

The previous illustration 65
shows that Pilot Assist
is set to maintain a speed of 110 km/h (68 mph) and that there is no target vehicle ahead to fol-low. In this example, Pilot Assist will provide steering assistance because it can detect the lane's sidemarking lines.

City Safety
™
City Safety can alert the driver with light, sound and pulsations in the brake pedal to help thedriver detect pedestrians, cyclists, large animalsand vehicles that appear suddenly – the vehiclewill then attempt to automatically brake if thedriver does not act within a reasonable amountof time.
Location of the camera and radar sensor 71
.
City Safety can help prevent a collision or lower the vehicle's speed at the point of impact. City Safety is an aid intended to assist the driver if a collision with a pedestrian, large animal,cyclist or vehicle is imminent. City Safety can help the driver avoid a collision when e.g. driving in stop-and-go traffic, when changes in the traffic ahead and driver distractioncould lead to an incident. The function assists the driver by automatically applying the brakes if there is an imminent risk ofa collision and the driver does not react in time bybraking and/or steering away. City Safety activates a brief, forceful braking in an attempt to stop your vehicle immediately behindthe vehicle or object ahead. City Safety is activated in situations in which the driver should have applied the brakes much ear-lier, which means that the system will not be ableto assist the driver in all situations. City Safety is designed to be activated as late as possible to help avoid unnecessary intervention. Normally, the occupants of the vehicle will not be aware of City Safety except when the systemintervenes when a collision is imminent.

City Safety limitations
City Safety functionality may be reduced in cer- tain situations.
Surroundings
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 function-ality.
Slippery road conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In these types of situations, the Anti-lock Braking System and Electronic Stability Con- trol (ESC 73
) will help provide optimal braking
power with maintained stability.
Backlighting
The visual warning signal in the windshield may be difficult to detect in bright sunlight, if there arereflections, or if the driver is wearing sunglassesor not looking straight ahead.
Heat
If the temperature in the passenger compartment is high due to e.g. bright sunlight, the visual warn-ing signal in the windshield may be temporarilydisabled.
Camera and radar sensor's field of vision
The camera's field of vision is limited and in cer- tain situations, it may be unable to detect pedes-trians, large animals, cyclists or vehicles, or it maydetect them later than expected. Vehicles that are dirty may be detected later than clean vehicles, and in dark conditions, motorcy-cles may be detected late or not at all. If a text message displayed in the instrument panel indicates that the camera/radar sensor isobstructed, it may be difficult for City Safety todetect pedestrians, large animals, cyclists, vehi-cles or lane markings in front of the vehicle. CitySafety functionality may therefore be reduced. Text messages may not be displayed for all situa- tions in which the windshield sensors areblocked. The driver must therefore always keepthe windshield in front of the camera/radar sen-sor clean.
CAUTION
Maintenance and replacement of City Safety components may only be performed by aworkshop – an authorized Volvo workshop isrecommended.
Driver intervention
Backing up
City Safety is temporarily deactivated when the vehicle is backing up.
Low speed
City Safety is not activated at very low speeds under 4 km/h (3 mph). The system will thereforenot intervene in situations in which your vehicle isapproaching another vehicle very slowly, such aswhen parking.
Active driver
Action by the driver always has priority. City Safety will therefore not react or will react at alater stage with a warning or intervention in situa-tions in which the driver is clearly steering andoperating the accelerator pedal, even if a collisionis unavoidable. An active and aware driving style may therefore delay collision warnings and intervention in order to minimize unnecessary warnings.
