The PAP sequence is stopped:
- if the car is driven too quickly - above 7 km/h
- if the driver touches the steering wheel
- if the ABS or DSTC function is activated - e.g. if a wheel loses grip on a slippery road.
A text message indicates where the PAP sequence was stopped.
Dirt, ice and snow covering the sensors will reduce their function and may prevent measurement.
Under certain circumstances, PAP is unable to find parking spaces - one reason for this may be the fact that there is interference with the sensors from external sound sources which emit the same ultrasound frequencies as those with which the system works.
Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes and exhaust noises from motorcycles etc.
To bear in mind
The driver should bear in mind that the Park Assist Pilot is an aid – not an infallible, fully-automatic function. The driver must therefore be prepared to intervene. There are also a few details to bear in mind while parking, e.g.:
- PAP starts out from the current location of the parked vehicles - if they are inappropriately parked then the car's tyres and wheel rims may be damaged against kerbs.
- PAP is designed for parking on straight streets, not sharp curves or bends. For this reason, make sure the car is parallel to the parking space when PAP measures the space.
- It is not always possible to find parking spaces on narrow streets since there is not enough space for manoeuvring. In such parking situations, it helps the system to drive as close to the side of the road as possible where you intend to park.
- Bear in mind that the front of the car may swing out towards oncoming traffic while being parked.
- Objects situated higher than the detection areas of the sensors are not included when calculations are made for the parking manoeuvre. This may cause PAP to swing into the parking space too early, and hence such parking spaces should be avoided.
- The driver is responsible for determining whether the space selected by PAP is suitable for parking.
- Use approved tyreswith the correct tyre pressure - this affects PAP's ability to park the car.
"Approved tyres" refers to tyres of the same type and make as those fitted new on delivery from the factory.
- Heavy rain or snow may cause the system to measure the parking space incorrectly.
- Do not use PAP if snow chains or a spare wheel are fitted.
- Do not use PAP if loaded objects are protruding from the car.
The PAP system's parameters may need to be updated when changing to another approved wheel rim size involving changed tyre circumference. Consult a workshop - an authorised Volvo workshop is recommended.
The PAP sensors are located in the bumpers
The figure is schematic and therefore does not show the car model in question.
For the PAP function to work correctly, its sensors must be cleaned regularly with water and car shampoo - these are the same sensors as are used by parking assistance, see Park assist syst - cleaning the sensors.
