Note that the steering wheel can "spring" backwhen the procedure is completed and the drivermay need to turn the steering wheel back to themaximum position in order to pull out of the park-ing space.
If PAP determines that the driver can pull out ofthe parking space without any extra maneuvers,the function will be deactivated, even if it seemsas though the vehicle is not completely out of theparking space.

Park Assist Pilot* limitations
Park Assist Pilot PAP120 may not be able todetect all conditions in all situations and func-tionality may therefore be limited.
WARNING
The PAP function is supplementary driversupport intended to facilitate driving andhelp make it safer – it cannot handle allsituations in all traffic, weather and roadconditions.
Pay particular attention to people andanimals near the vehicle.
Bear in mind that the front end of thevehicle may swing out towards oncomingtraffic during the parking maneuver.
Objects situated higher than the detec-tion area of the sensors are not includedwhen the parking maneuver is calculated,which could cause PAP to swing into theparking space too early. Such parkingspaces should be avoided for this reason.
PAP is not a substitute for the driver'sattention and judgment. The driver isalways responsible for ensuring the vehi-cle is driven in a safe manner, at theappropriate speed, with an appropriatedistance to other vehicles, and in accord-ance with current traffic rules and regula-tions.
The driver should be aware of the following limi-tations for Park Assist Pilot:

The parking sequence is cancelled
A parking sequence will be cancelled if:
the driver moves the steering wheel
the vehicle's speed exceeds 7 km/h (4 mph)
the driver taps Cancel in the center display
when the anti-lock brakes or the Electronicstability control are engaged - e.g. when awheel loses grip on a slippery road
when the power steering works at reducedpower - e.g. during cooling due to overheat-ing (see section "Speed-dependent steeringforce").
A message in the center display will explain whythe parking sequence was cancelled.

CAUTION
Under certain circumstances, PAP may not beable to find parking spaces – one reason maybe that the sensors are disrupted by externalsound sources that emit the same ultrasonicfrequencies that the system works with.
Examples of such sources include horns, wettires on asphalt, pneumatic brakes, exhaustnoise from motorcycles, etc.
NOTE
Dirt, ice and snow covering the sensorsreduce their function and can make measure-ment impossible.

Driver responsibility
The driver should keep in mind that PAP is aparking aid ‒ not an infallible fully automatic sys-tem. The driver must always be prepared to takecontrol and cancel a parking sequence if neces-sary.
There are a number of things to keep in mindwhen parking, including:
The driver is always responsible for determin-ing if the space suggested by PAP is suita-ble for parking.
Do not use PAP when using snow chains ora temporary spare tire.
Do not use PAP if there are any objects pro-truding from the vehicle.
Heavy rain or snowfall may inhibit PAP's abil-ity to accurately measure a parking space.
While searching and measuring the parkingspace, PAP may be unable to detect objectslocated far into the space.
PAP may not suggest parking spaces onnarrow streets if it does not detect sufficientspace for maneuvering the vehicle.
Use approved tires121 inflated to the correcttire pressure because this affects PAP's abil-ity to provide parking assistance.
PAP's function is based on the way the vehi-cles are parked behind and in front of yourparking 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.
Perpendicular parking spaces may not bedetected or may be suggested unnecessarilyif a parked vehicle is sticking out more thanother parked vehicles.
PAP is intended to provide parking assis-tance on straight streets, not sections ofstreet with sharp curves or bends. Alwaysmake sure that your vehicle is parallel to rel-evant parking spaces when PAP is measur-ing the parking space.

CAUTION
Switching to another approved wheel and/ortire dimension could change the tire circum-ference, which would then require the PAPsystem to be updated. Consult a workshop –an authorized Volvo workshop is recom-mended.
121"Approved tires" refers to tires of the same type and make as the vehicle's original, factory-installed tires.

Hill Start Assist
The function for assisting when starting the vehi-cle on inclines, Hill Start Assist (HSA), helpsprevent the vehicle from rolling backward whenstarting on an uphill gradient. When backing upa hill, HSA helps prevent the vehicle from rollingforward.
The function retains pressure from the brakepedal in the brake system for several secondsafter the brake pedal has been released.
This temporary braking effect is released after afew seconds or when the driver begins driving.
Hill Start Assist is available even if the Auto-holdbrake function is switched off.

Braking assist after a collision
In a collision in which the activation level isreached for the pyrotechnic seat belt tensionersor airbags, or if a collision with a large animal isdetected, the vehicle's brakes will be automati-cally activated. This function is intended to helpprevent or reduce the effects of any subsequentcollision.
After a serious collision, it may no longer be pos-sible to control and steer the vehicle. In order toavoid or mitigate a possible further collision witha vehicle or an object in the vehicle's path, thebrake assist system is activated automatically tohelp stop the vehicle safely.
The brake lights and hazard warning flashers areactivated during braking. When the vehicle hasstopped, the hazard warning flashers will con-tinue to flash and the parking brake will beapplied.
If braking is not appropriate, e.g. if there is a riskof being hit by passing traffic, the driver can over-ride the system by depressing the acceleratorpedal.
This function assumes that the brake system isintact after a collision.
Brake assist is part of the Rear Collision Warningand Blind Spot Information safety systems.
