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.
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 or thesystem may not function at all.

Backing up
Location of the rear Park Assist Camera (generic illus- tration)
The rear camera shows a wide area behind the vehicle and on certain models, part of the bumperand the trailer hitch (if installed) will be visible. Some objects on the screen may appear to “lean” slightly, which is normal.
WARNING
People/objects/obstructions displayed on the center console screen may be closer to thevehicle than they appear.
Front camera
Location of the front Park Assist Camera (generic illus- tration)
The front camera is located behind the grill and can be useful when driving off in areas with lim-ited visibility (hedges, bushes, etc). It is active atspeeds up to approx. 16 mph (25 km/h) and isautomatically turned off when the vehicleexceeds this speed. However, if the vehicle's speed does not exceed 30 mph (50 km/h) and its speed goes under14 mph (22 km/h) within 60 seconds after thecamera has been switched off, the front camerawill reactivate.
NOTE
The front camera will only reactivate automati- cally if Auto Camera Reverse Activation
has been selected in SettingsMy CarPark Assist.
Side camera
The side cameras are located in the respective door mirrors and show views along the sides ofthe vehicle.

trajectory lines and fields
The Park Assist Camera system uses trajectory lines and fields to indicate the vehicle's positionin relation to its immediate surroundings.
Trajectory lines
Sample guidelines
The trajectory lines are intended to show the position of the vehicle's outermost dimensionsbased on the current position of the steeringwheel to help simplify parallel parking, backinginto tight spaces or when attaching a trailer. The lines on the screen are projected as if they were a path on the ground around the vehicleand are directly affected by the way in which thesteering wheel is turned. This enables the driverto see path the vehicle will take, even if he/sheturns the steering wheel. These lines also indicate the outermost limits thatany object (door mirrors, corners of the body, atrailer hitch, etc.) extends out from the vehicle,even when it turns.
NOTE
When backing up with a trailer, the trajectory lines show the path that the
vehicle will take,
not the trailer. Trajectory lines will not be displayed while zooming in.
WARNING
Keep in mind that when the rear camera has been selected, the image on the screen onlyshows the area behind the vehicle. The drivermust always watch for people, animals, othervehicles, etc., near the sides or the front of thevehicle when turning while backing up. The opposite is true when the front camera is selected. Please note that the trajectory lines show the shortest path. Be sure that the vehicle

Perpendicular parking
Procedure for perpendicular parking
PAP helps park the vehicle as follows:
1. The system searches for and measures a
possible parking space. While this is being done, the vehicle's speed may not exceedapprox. 4 mph ( 7 km/h).
2. The vehicle is steered while it is backing into the parking space and its position in thespace is adjusted by prompting the driver to select D or R while the system steers. The
driver has to control the vehicle's speed.
NOTE
PAP's Park out function cannot be used to
help a vehicle leave a parking space if the
Perpendicular parking function was used
to park the vehicle.
WARNING
• PAP does not function in all situations and is only intended to assist the driverduring parallel or perpendicular parking.
• As the driver, you have full responsibilityfor parking the vehicle in a safe manner.

Using Park Assist Pilot (PAP) *
Park Assist Pilot (PAP) gives the driver instruc- tions during the parking procedure. The functioncan also assist when leaving a parking space.
NOTE
While PAP is active, the driver's task is to:
• carefully monitor the area around the vehicle
• follow the instructions provided in thecenter display
• select a gear (
D or R) when prompted
• regulate the vehicle's speed
• apply the brakes when necessary andstop the vehicle
Symbols, images and text in the center display indicate when the various steps in the parkingprocedure will be carried out. PAP can be activated if the following conditions are met after the engine has started:
• The vehicle may not be towing a trailer.
• The vehicle's speed must be below approx.20 mph (30 km/h).
• The distance between the vehicle and aparking space must be between 1.6-5.0 ft(0.5-1.5 m)

358 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 willbe 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 in
the center display's Function view.
1. Tap the Park out button in the center display's
Function view. 2. Use the turn signal to indicate the direction in which the vehicle should leave the parking space. 3. Follow the instructions provided in the center display. The procedure is the same as when park-ing 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.

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 whythe 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.

DRIVER SUPPORT

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 thevehicles 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 between1.5-5.0 ft (0.5-1.5 m) from the side of theroad where the 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
In order for PAP to function correctly, these sen- sors must be cleaned regularly with water and asuitable car washing detergent.

STARTING AND DRIVING
* Option/accessory.
362
Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles *.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function.
WARNING
If the vehicle does not have electrical current and both the electric motor and gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle is carrying a heavy load, using brake mode B to
augment the brakes or the
Off Road* drive mode can also be used on steep downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System
ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Function check when the engine is
started
A Plug-in Hybrid is equipped with a "brake bywire" brake system. A function check is per-formed each time the engine is started and thedriver depresses the brake pedal to move the gear selector from P.
In certain cases, a message may appear in the instrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.
Light braking charges the hybrid batteryWhen the brakes are applied lightly, the electricmotor's braking function is used, which converts
