or twice as needed according to the instruc- tions in the previous section "Turning ACC offcompletely." The next time the system isswitched on, ACC will be reactivated.
Queue Assist
IntroductionQueue Assist is an added ACC feature that is linked to your vehicle's automatic transmis-sion. Queue Assist consists of the following func- tions: • Enhanced speed interval (including when the vehicle is at a complete stop or is moving at speed below 18 mph(30 km/h))
• Automatic standby mode when ACCchanges target vehicles
• No automatic braking when at a standstill
• The parking brake is applied automati-cally
Please note that the lowest speed that can be set is 18 mph (30 km/h), although ACC canmaintain a set speed/distance to a vehicleahead down to a standstill. Queue Assistconsists of the following features:
Enhanced speed interval
NOTE
The driver's door must be closed and the driver's seat belt must be fastened beforeACC can be put in active mode. If the driv-er's seat belt is taken off or if the driver'sdoor is opened, ACC will return to standbymode.

Introduction
Distance Alert is part of Adaptive Cruise Con- trol and is a function that provides informa-tion about the time interval to the vehicleahead. Distance Alert is active at speeds above approximately 18 mph (30 km/h). Time inter-val information is only given for a vehicle thatis driving ahead of your vehicle in the samedirection. No information is provided for vehi-cles driving toward you, moving very slowly,or at a standstill.
Amber warning light 1
.
An amber warning light in the windshield glows steadily if your vehicle is closer to theone ahead than the set time interval.

Collision warning with Full Auto-brake and Pedestrian Detection*
04
162* Option/accessory, for more information, see Introduction.
Introduction
Collision Warning with Full Auto-brake and Pedestrian Detection is designed to assist thedriver if there is a risk of a collision with apedestrian, a vehicle ahead that is at a stand-still or one that is moving in the same direc-tion as your vehicle. Collision Warning consists of the following three functions:
• Collision Warning
warns the driver of a
potential collision situation.
• Brake Support
helps the driver brake
efficiently in a critical situation.
• Auto-brake
brakes the vehicle automati-
cally if a collision with a pedestrian or another vehicle cannot be avoided andthe driver does not apply the brakes intime or steer around the person/vehicle.Auto-brake can help prevent a collision orreduce the speed at which a collisionoccurs.
Since Collision Warning with Full Auto-brake and Pedestrian Detection is activated in cir-cumstances where the driver should havebegun braking much sooner, the system willnot be able to assist the driver in all situa-tions. This system is designed to activate as late as possible to help avoid unnecessary interven-tion. The system should not be used in such a waythat the driver changes his/her way of operat-ing the vehicle. If the driver relies entirely onthe system, the chances of an accident even-tually occurring increase considerably. The Collision Warning and City Safety™ sys- tems supplement each other. See page 156for detailed information about City Safety™.
WARNING
No automatic system can be guaranteed to function 100% correctly in all situations.For that reason, never test the Auto-brakesystem by driving toward a person orobject. This could result in serious injury ordeath.
WARNING
•
Collision Warning does not work in all driving, traffic, weather and road con-ditions. It does not react to vehiclesnot traveling in the same direction asyour vehicle.
• Collision Warning does not react toanimals.
• Warnings are only provided when therisk of collision is high. The "Function"section provides information aboutlimitations that the driver must beaware of before using Collision Warn-ing.
• Collision Warning will not provide awarning or brake the vehicle forpedestrians at speeds above 50 mph(80 km/h).

* Option/accessory, for more information, see Introduction.177
Signals from the park assist system
View in the display (warning for objects front left/ right rear)
Visual indicatorThe audio system’s display gives an overview of the vehicle’s position in relation to adetected object. The marked sectors in the display indicate that one or more of the sensors has detectedan object. The closer the car symbol comesto a sector, the closer the vehicle is to theobject. If the infotainment system is switched off, the park assist system will not be able to providea visual indicator. An audible signal will stillbe provided.
Audible signalThe Park Assist system uses an intermittenttone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. Ifthere are objects within this distance bothbehind and in front of the vehicle, the tonealternates between front and rear speakers.
NOTE
The level of the audible signal can be low- ered/raised with the infotainment volumecontrol. The level can also be set in the MYCAR menu system. See page 193 for adescription of the menu system.
If the volume of another source from the audio system is high, this will be automati-cally lowered.
Rear park assist
G021423
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.

178* Option/accessory, for more information, see Introduction.
NOTE
• Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see page 176.
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.
Front park assist
G021424
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audiblesignal comes from the audio system's frontspeakers. It may not be possible to combine auxiliary headlights and front park assist since theselights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the parking brake is applied and or when thegear selector is in the
P position.
Faults in the system
If the information symbol illuminates andPark assist syst Service required is shown
on the information display, this indicates that the system is not functioning properly andhas been disengaged. Consult a trained andqualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.

Blind Spot Information System (BLIS)*
04
* Option/accessory, for more information, see Introduction.185
When does BLIS function
The system functions when your vehicle is moving at speeds above 6 mph (10 km/h).
When you pass another vehicle:The system reacts when you pass another vehicle at a speed of up to 6 mph (10 km/h)faster than that vehicle.
When you are passed by another
vehicle:
The system reacts if your vehicle is passed by another vehicle at a speed of up to 43 mph(70 km/h) faster than your vehicle.
WARNING
• BLIS does not function in sharp curves.
• BLIS does not function when yourvehicle is backing up.
• If you are towing a wide trailer, thismay prevent the BLIS cameras fromdetecting other vehicles in adjacentlanes.
How BLIS functions in daylight and darkness
DaylightBLIS reacts to the
shape of surrounding vehi-
cles. The system is designed to help detect motor vehicles such as cars, trucks, buses, motorcycles, etc.
DarknessBLIS reacts to the
headlights of surrounding
vehicles. In order to be detected by BLIS, a vehicle in the blind area must have its head-lights on. This means, for example, that thesystem will not detect a trailer without head-lights that is being towed behind a car ortruck.
WARNING
• BLIS does not react to cyclists or mopeds.
• BLIS does not react to vehicles thatare standing still.
• The BLIS cameras have the same limi-tation as the human eye. In otherwords, their "vision is impaired" byadverse weather conditions such asheavy snowfall, intense light directlyinto the camera, dense fog, etc.
LimitationsIn certain situations, the BLIS indicator light(s) may illuminate even when there are no othervehicles in the area monitored by the system.
NOTE
If the BLIS indicator lights illuminate occa- sionally even when there are no other vehi-cles in the blind area, this does not indi-cate a fault in the system. In the event of a fault,
Blind spot syst.
Service required will be displayed.
The following are several examples of situa- tions in which the BLIS indicator light(s) mayilluminate even when there are no other vehi-cles in the area monitored by the system.
