Limitations of Park Assist Pilot*

The Active parking assistance (Park Assist Pilot – PAP) function may have limitations in certain situations.

Parking is discontinued

A parking sequence will be discontinued:
  • if the driver moves the steering wheel
  • if the car is driven too quickly - above 7 km/h (4 mph)
  • if the driver presses Cancel in the centre display
  • when the anti-lock brakes or the Electronic stability control are engaged - e.g. when a wheel loses grip on a slippery road.

Where applicable, a message in the centre display states the reason for a parking sequence being discontinued.


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.

Driver responsibility

The driver should bear in mind that the PAP is an aid – not an infallible, fully-automatic function. The driver must therefore be prepared to interrupt a parking step.

There are also a few details to bear in mind while parking, e.g.:
  • PAP bases itself on the locations of vehicles already parked nearby - if they are inappropriately parked, your own car's tyres and wheel rims may be damaged by contact with the kerb.
  • 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.
  • Parking spaces on narrow streets are not always feasible, since the space required for manoeuvring may not be sufficient.
  • 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 taken into account when calculating the parking manoeuvre. This may cause PAP to turn 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 tyres1 with the correct tyre pressure - this affects the ability of PAP to park the car.
  • 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 cargo items are protruding from the car.
  • Perpendicular parking spaces may be missed or offered unnecessarily if one parked car is protruding more than other parked cars.


Changing to another approved wheel rim and/or tyre dimension may involve a changed tyre circumference, which means that the PAP system's parameters may then need to be updated. Consult a workshop - an authorised Volvo workshop is recommended.

For the PAP function to work correctly, its sensors must be cleaned regularly with water and car shampoo.
