RSI may have difficulty reading signs that are:
• Faded
• Located in a curve
• Twisted or damaged
• Positioned high above the road
• Obstructed (by bushes, etc.)
• Partially covered by snow, ice, etc.
The camera used by RSI (and other driver sup- port systems such as Adaptive Cruise Control *)
has certain limitations. See the article "City Safety limitations" for additional information.
NOTE
RSI may perceive certain types of bicycle holders (with wiring attached to the trailerelectrical socket) as a trailer, which may resultin faulty speed limit information to the driver.

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 tone becomes constant when you are within approximately 1 ft (30 cm) of an object and theinnermost sensor field will be red. If there areobjects within this distance both behind and infront of the vehicle, the tone alternates betweenfront and rear speakers. 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 Setting menu.
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.
Side park assist
The system's side sensors are activated automat- ically when the engine is started and are active atspeeds below approximately 6 mph (10 km/h). The distance monitored along the sides of thevehicle is approximately 1 ft (0.3 m). The audiblesignal comes from the side speakers.
Front park assist
The system's front sensors are activated auto- matically when the engine is started and areactive at speeds below approximately 6 mph(10 km/h). The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audible signalcomes from the front speakers. Front Park Assist is deactivated if the parking brake is applied or if the gear selector is put in
P.
When installing auxiliary headlights, be sure that they do not obstruct the front sensors. Otherwise,these lights could trigger a Park Assist warning.

Park Assist limitations
The Park Assist system has certain limitations.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will be takeninto account when measuring the availablespace behind the vehicle.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.309
NOTE
•The system will not detect high objects, such as a loading dock, etc.
• Certain materials or fabrics may not bedetected by the sensors. Objects made ofthese materials or people wearing cloth-ing made of these fabrics may not bedetected.
• Children or animals near the vehicle maynot always be detected.
• Objects such as chains, thin shiny polesor low objects may temporarily not bedetected by the system. This may resultin the pulsing tone unexpectedly stoppinginstead of changing to a constant tone asthe vehicle approaches the object. Insuch cases, use caution when backing upor stop the vehicle to help avoid damage.
• In certain circumstances, the park assistsystem may give unexpected warning sig-nals that can be caused by externalsound sources that use the same ultra-sound frequencies as the system. Thismay include such things as the horns ofother vehicles, wet tires on asphalt, pneu-matic brakes, motorcycle exhaust pipes,other vehicles with similar ultrasound sys-tems, etc. This does not indicate a fault inthe system.
Cleaning the sensors
Location of the Park Assist sensors
The sensors must be cleaned regularly to ensure that they work properly. Clean them with waterand a suitable car washing detergent.
NOTE
If the sensors are obstructed by e.g., dirt, snow, or ice, this could result in false warningsignals from the park assist system.

320 adjusted by driving slightly forward and backing up. 1.
Put the gear selector in D, wait until the
steering wheel has turned and drive forward slowly.
2. Stop the vehicle when you are instructed by PAP to do so.
3. Put the gear selector in R, back up slowly
and stop when you are instructed by PAP todo so.
When the parking procedure is finished (this will be indicated by a text message and a graphicimage), PAP switches off automatically. If neces-sary, the driver may need to make minor adjust-ments to ensure that the vehicle is parked cor-rectly.
CAUTION
The warning distance is shorter when PAP is using the sensors than when Park Assist isusing them.
Leaving a parking spaceThis function can only be used for a vehicle that has been par-allel parked and is activated inthe center display's Functionview. 1. Tap the
Park out button in
the center display's Function view.
2. Follow the instructions provided. The proce- dure is the same as when parking the vehicle. The steering wheel may turn back slightly when the function is completed and the driver mayhave to turn the back before leaving the parkingspace. If PAP determines that the driver can leave the parking space without assistance, the functionwill deactivate before the vehicle is completelyout of the space.

Park Assist Pilot (PAP) * limitations
The PAP function may be limited in certain situa- tions.
The PAP parking sequence is cancelledA parking sequence will be cancelled:
• if the vehicle is driven too fast (above approx. 4 mph (7 km/h)
• if the driver taps
Cancel in the center display
• if the driver moves the steering wheel with sufficient force.
• if the anti-lock brakes or Electronic StabilityControl are activated (e.g., if a wheel beginsto spin or lose traction)
In such cases, a text message will explain why the parking sequence was cancelled.
NOTE
• PAP will not function correctly if its sen- sors are obstructed by dirt, snow, etc.
• In certain situations, PAP may not be ableto measure a parking space. This couldbe due to external sources of sound (e.g.,a vehicle's horn, tires on wet asphalt,pneumatic brakes, noise from a motorcy-cle's exhaust, etc.) emitting ultrasoundusing approximately the same frequen-cies as PAP.

Points to keep in mindPAP is a parking aid only and the driver should always be prepared to take control and cancel aparking sequence. This can be due to one ormore of the following factors:
• PAP's function is based on the way that the vehicles are parked behind and in front ofyour parking space. If they are, for example,parked too close to the curb, there is a riskthat your vehicle's tires or wheel rims couldbe damaged by the curb during the parkingprocedure.
• PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with curved or irregular curbs. Be surethat your vehicle is parallel to the curb whenPAP measures the parking space.
• PAP may not be able to provide parkingassistance on narrow streets due to lack ofspace to maneuver the vehicle. In situationslike this, it may help to drive between 1.5-5 ft(0.5-1.5 m) from the side of the road wherethe parking space is located.
• Use only approved tires with the correct infla-tion pressure because this affects PAP'scapacity to provide parking assistance.Changing to a different approved tire sizemay affect PAP's parameters. Consult atrained and qualified Volvo service technician.
• Heavy rain or snow may inhibit PAP'scapacity to correctly measure a parkingspace. •
Do not use PAP when using snow chainsand/or a temporary spare tire.
• Do not use PAP if there are any objects pro-truding from the vehicle.
WARNING
• The front end of your vehicle may turn out toward oncoming traffic during the park-ing procedure.
• Objects located above the parking sen-sors' field of vision are not included whenPAP measures a parking space. For thisreason, PAP may turn into the parkingspace too soon. Avoid parking spaces ofthis type.
• The driver is always responsible for deter-mining if PAP has selected a suitableparking space.
Maintenance
Location of the PAP sensors
PAP uses the same sensors as the Park Assist system. To function correctly, these sensors mustbe cleaned regularly with water and a suitable carwashing detergent.
