Passing Assistance with Adaptive Cruise Control or Pilot Assist
ACC or Pilot Assist can assist the driver when passing other vehicles.
How passing assistance worksWhen ACC or Pilot Assist is following another vehicle and the driver indicates that he/she isabout to pass that vehicle by using the left turnsignal, ACC or Pilot Assist will begin acceleratingtoward the vehicle ahead before your vehicle hasmoved into the passing lane. The function will then delay a speed reduction to avoid early braking as your vehicle approachesthe slower-moving vehicle. The function is active until your vehicle has passed the other vehicle.
WARNING
Be aware that this function may be activated in situations other than when passing a vehi-cle, such as if the turn signal is used to indi-cate a lane change or to indicate a turn. Thevehicle will accelerate briefly.
Using passing assistanceTo activate passing assistance:
• Your vehicle (ACC or Pilot Assist) must be following another vehicle (the target vehicle).
• Current speed must be at least approx.45 mph (70 km/h ). •
The speed set for ACC or Pilot Assist mustbe high enough to safely pass the vehicleahead.
Starting passing assistanceTo start a passing assistance sequence:
• Activate the left turn signal.
Passing assistance limitations
WARNING
The driver should be prepared for sudden changes when passing assistance is used. Incertain cases, there may be undesired accel-eration. Certain situations should be avoided, such as: • If the vehicle is approaching an exit to the left or a left turn.
• If the vehicle ahead slows down beforeyour vehicle has moved into the passinglane.
• Traffic in the passing lane slows down.
Passing assistance in these situations can bedeactivated by putting ACC or Pilot Assist instandby mode.

Changing target vehicles and automatic braking with AdaptiveCruise Control (ACC)
At certain speeds, Adaptive Cruise Control can change target vehicles and automatically applythe brakes.
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.

Adaptive Cruise Control (ACC) - limitations
Adaptive Cruise Control (ACC) functionality may be limited in certain situations.
Steep roads and/or heavy loadsAdaptive Cruise Control is primarily intended for use on relatively level roads. The function may notbe able to maintain the correct time interval tothe vehicle ahead when driving down steep hills.The driver should be attentive and prepared toapply the brakes in these situations. Do not use Adaptive Cruise Control when the vehicle is transporting a heavy load or if it is tow-ing a trailer.
Additional information
• The Off Road drive mode cannot be
selected if Adaptive Cruise Control is acti- vated.
• Adaptive Cruise Control uses the vehicle'scamera and radar sensor, which have certaingeneral limitations. See the articles "Cameralimitations" and "Radar sensor limitations"for additional information.

284sensor, the system may apply the brakes in your vehicle suddenly or not at all. Pilot Assist is designed to follow a vehicle ahead in the same traffic lane at a preset time intervalset by the driver. If the radar sensor does notdetect a vehicle ahead, the vehicle will insteadmaintain the speed set by the driver. This will alsobe the case if a vehicle ahead accelerates andexceeds the set speed.
• Pilot Assist can follow another vehicle from astandstill up to a speed of approx. 125 mph(200 km/h)
• Pilot Assist can provide steering assistancefrom very low speeds up to approx. 87 mph(140 km/h).
Never exceed posted speed limits.
WARNING
• Pilot Assist is not a collision avoidance system. The driver must react if the sys-tem does not detect another vehicle.
• Pilot Assist does not react to people, ani-mals, stationary objects, small vehicles(such as bicycles and motorcycles), lowtrailers and slow moving, parked orapproaching vehicles.
• Do not use Pilot Assist in demandingdriving conditions such as city driving orother heavy traffic situations, in areas withintersections, in slippery conditions, whenthere is a great deal of water or slush onthe road, during heavy rain or snow, inpoor visibility, on winding roads, on high-way on- or off-ramps or if the vehicle istowing a trailer, boat, etc.
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 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 driving conditions 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 Pilot Assist 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 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 PilotAssist.
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. 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 be
selected if Pilot Assist is activated.
• Pilot Assist uses the vehicle's camera and radar sensor, which have certain general limi-tations. See the articles "Camera limitations"and "Radar sensor limitations" for additionalinformation.

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 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
Warning.
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, Rear Collision Warning (RCW) will
not activate the rear turn signals.
That part of the function will be deacti- vated.
• The use of the rear turn signals will alsobe deactivated if the City Safety warning level is set at
Later. See also the section

Park Assist *
The Park Assist system is designed to assist you
when driving into parking spaces, garages, etc. An audible signal and symbols in the instrumentpanel and center display indicate the distance tothe object.
Display view showing object zones and sensor sectors
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The highlighted sector shows which of the sen- sors has detected the object. The closer thehighlighted sector is to the vehicle symbol, thecloser the actual object is to your vehicle. The Park Assist system uses an intermittent tone that pulses faster as you come closer to anobject. Sound from the infotainment system willbe temporarily turned down. The audible signals for objects in front of and tothe sides are active while the vehicle is movingand will stop after the vehicle has been stoppedfor approx. 2 seconds. The audible signals forobjects behind the vehicle are active even whenthe vehicle has stopped moving. The audible signal becomes constant when you are within approximately 1 ft (30 cm) of an objectand the highlighted sensor field is filled in. While an audible signal is being given, its volume level can be raised/lowered using the
>II control
in the center console or can be adjusted in the center displays Top view under
Settings.
NOTE
Audible alerts will only be provided for objects that are directly in the vehicle's path.
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to bea supplementary aid when parking the vehicle.It is not, however, intended to replace the driv-er's attention and judgement.
Rear park assist
The system's rear sensors are activated automat- ically when the engine is started and are active ifthe vehicle rolls rearward with the gear selector in N or if R has been selected.
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The rear sensors will be deactivated automatically when towing a trailer if Volvo genuine trailer wir-ing is used. If a non-Volvo trailer hitch is beingused, it may be necessary to switch off the sys-tem manually.
