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 thevehicle
•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 displayindicate when the various steps in the parkingprocedure will be carried out.
PAP can be activated if the following conditionsare 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)
NOTE
If a trailer hitch is configured in the vehicle'selectrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.

Parking
Procedure for parking:
1. The system searches for and measures apossible parking space.
2. The vehicle is steered while it is backing intothe parking space.
3. The vehicle's position is adjusted in the park-ing space by moving forward and rearward.

1: Searching and measuring
Parallel parking
Perpendicular parking
PAP searches for a potential parking space andmeasures it to see if there is sufficient space foryour vehicle. To start this procedure:
1. Tap the Park In button inthe center display's Functionview.
If necessary, slow down to:
•a speed below 20 mph (30 km/h) for parallelparking
•approx. 12 mph ( 20 km/h) for perpendicularparking.
2.Keep an eye on the display and be preparedto stop the vehicle when you are instructedby PAP to do so.
3.Select Parallel parking or Perpendicularparking and put the transmission in reverse.
4.Keep an eye on the display and be preparedto stop the vehicle when you are instructedby PAP to do so.
5. Stop the vehicle when instructed to do so.

NOTE
PAP normally searches for available parkingspaces along the curb on the right (passeng-er's) side of the vehicle. However, it can alsoassist in finding and parking in spaces on thedriver's side. To do so:
•Activate the left turn signal. PAP will thensearch for a parking space on the leftside of the vehicle.
2: Backing into the parking space
Parallel parking
Perpendicular parking

371
When the vehicle is backing up, PAP will steer itinto the parking space. Do as follows:
1.Check that the area behind the vehicle isclear and put the gear selector in R.
2. Back up slowly without moving the steeringwheel. The vehicle's speed must be belowapproximately 4 mph (7 km/h).
3. Keep an eye on the instrument panel and beprepared to stop the vehicle when you areinstructed by PAP to do so.

NOTE
•Release the wheel while PAP is steeringthe vehicle.
•The steering wheel must be able to turnfreely.
•For PAP to function optimally, wait untilthe steering wheel is no longer turningbefore beginning the next phase of theparking procedure.
3: Adjusting the vehicle's position
Parallel
Perpendicular
After the vehicle has backed into the parkingspace, its position in the space has to be
adjusted by driving slightly forward and backingup.
1.Put the gear selector in D, wait until thesteering wheel has turned and drive forwardslowly.
2.Stop the vehicle when you are instructed byPAP to do so.
3.Put the gear selector in R, back up slowlyand 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 isusing the sensors than when Park Assist isusing them.

Leaving a parking space
This function can only be usedfor 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'sFunction view.
2. Use the turn signal to indicate the direction inwhich the vehicle should leave the parking space.
3. Follow the instructions provided in the centerdisplay. The procedure is the same as when park-ing the vehicle.
The steering wheel may turn back slightly whenthe function is completed and the driver mayhave to turn the back before leaving the parkingspace.
If PAP determines that the driver can leave theparking 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 cancelled
A 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 withsufficient 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.
Points to keep in mind
PAP is a parking aid only and the driver shouldalways 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.

DRIVER SUPPORT
* Option/accessory, for more information, see Introduction.373
•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 outtoward 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, for more information, see Introduction.376
Starting and driving
The vehicle is equipped with an automatic trans-mission that also makes it possible to shift gearsmanually.
Certain functions can also be used when theengine is not running, depending on the ignitionmode being used.

•Starting the engine (p. 402)
•Ignition modes (p. 400)
•Automatic transmission (p. 424)
•Opening/closing the fuel filler door (p. 393)
•Parking brake (p. 382)
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 system
If 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 fartherthan normal and requires greater foot pressure,the stopping distance will be longer.
Pressure on the brake pedal is enhanced by thepower braking function.

WARNING
If the vehicle does not have electrical currentand 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 iscarrying a heavy load, using brake mode B toaugment the brakes or the Off Road* drive
mode can also be used on steep downgrades toincrease 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 somevibration in the brake pedal, which is normal.
The system performs a brief self-diagnostic testwhen 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 thegear selector from P.
In certain cases, a message may appear in theinstrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.

Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor's braking function is used, which converts

kinetic energy into electricity that is used tocharge the hybrid battery. This is indicated in theinstrument panel, see also the article "Generalinformation about the XC90 T8 Twin EnginePlug-in Hybrid".
Battery charging gauge in the instrument panel
This function is active at speeds from approx.90 mph (150 km/h) down to 3 mph (5 km/h).When braking at speeds outside of this range orduring harder braking, the hydraulic brake systemis used.

Cleaning the brake discs
Coatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wetweather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.
Driving on wet or salted roads
Prolonged driving on wet or salted roads canaffect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.

Brake pad inspection
On vehicles equipped with a jack*, the conditionof the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake pads.

WARNING
•If the vehicle has been driven immediatelyprior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
•Apply the parking brake and put the gearselector in the Park (P) position.
•Block the wheels standing on the ground,use rigid wooden blocks or large stones.
WARNING
•Use the jack intended for the vehiclewhen changing a tire. For any other job,use stands to support the vehicle.
•The jack should be kept well-greased andclean, and should not be damaged.
•Be sure the jack is on a firm, level, non-slippery surface.
•No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
•The jack must correctly engage the jackattachment.
•Never allow any part of your body to beextended under a vehicle supported by ajack.

Brake functions
The vehicle's standard braking features are aug-mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parkingbrake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill.
These systems include:
•Auto-hold brakes
•Hill Start Assist
•Braking assist after a collision
•Hill Descent Control*
