Limitations of Park Assist Pilot *
The Active parking assistance (Park Assist Pilot – PAP) function may have limitations in certainsituations.
Parking is discontinuedA 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 awheel loses grip on a slippery road.
Where applicable, a message in the centre dis-play states the reason for a parking sequencebeing discontinued.
NOTE
Dirt, ice and snow covering the sensors will reduce their function and may prevent meas-urement.
IMPORTANT
Under certain circumstances, PAP is unable to find parking spaces - one reason for thismay be the fact that there is interference withthe sensors from external sound sourceswhich emit the same ultrasound frequenciesas those with which the system works. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles etc.
Driver responsibilityThe driver should bear in mind that the PAP is an aid – not an infallible, fully-automatic function.The driver must therefore be prepared to inter-rupt a parking step. There are also a few details to bear in mind while parking, e.g.:
• PAP bases itself on the locations of vehiclesalready parked nearby - if they are inap-propriately parked, your own car's tyres andwheel rims may be damaged by contact withthe kerb.
• PAP is designed for parking on straightstreets - not sharp curves or bends. For thisreason, make sure the car is parallel to theparking space when PAP measures thespace. •
Parking spaces on narrow streets are notalways feasible, since the space required formanoeuvring may not be sufficient.
• Bear in mind that the front of the car mayswing out towards oncoming traffic whilebeing parked.
• Objects situated higher than the detectionareas of the sensors are not taken intoaccount when calculating the parkingmanoeuvre. This may cause PAP to turn intothe parking space too early, and hence suchparking spaces should be avoided.
• The driver is responsible for determiningwhether the space selected by PAP is suita-ble for parking.
• Use approved tyres 28
with the correct tyre
pressure - this affects the ability of PAP topark the car.
• Heavy rain or snow may cause the system tomeasure the parking space incorrectly.
• Do not use PAP if snow chains or a sparewheel are fitted.
• Do not use PAP if cargo items are protrudingfrom the car.
• Perpendicular parking spaces may be missedor offered unnecessarily if one parked car isprotruding more than other parked cars.
28
"Approved tyres" refers to tyres of the same type and make as those fitted new on delivery from the factory.

IMPORTANT
Changing to another approved wheel rim and/or tyre dimension may involve a changedtyre circumference, which means that thePAP system's parameters may then need tobe updated. Consult a workshop - an author-ised Volvo workshop is recommended.

Engine oil
An approved engine oil must be used in order that the recommended service intervals can beapplied.
Volvo recommends:
IMPORTANT
In order to fulfil the requirements for the engine's service intervals all engines are filledwith a specially adapted synthetic engine oilat the factory. The choice of oil has beenmade very carefully with regard to service life,starting characteristics, fuel consumption andenvironmental impact. An approved engine oil must be used in order that the recommended service intervals canbe applied. Only use a prescribed grade of oilfor both filling and oil change, otherwise thereis a risk of the service life, starting characte-ristics, fuel consumption and environmentalimpact of the car being affected. If engine oil of the prescribed grade and vis- cosity is not used, engine related componentsmay become damaged. Volvo Car Corporationdisclaims any liability for any such damage. Volvo recommends that oil changes are car- ried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/ high oil level or low oil pressure. Certain enginevariants have an oil pressure sensor, and then thedriver display's warning symbol for low oil pres- sure
is used. Other variants have an oil
level sensor, when the driver is informed via the driver display's warning symbol
and display texts. Certain variants have both systems. Contact a Volvo dealer for more information. Change the engine oil and oil filter in accordance with the intervals specified in the Service andWarranty Booklet. Using oil of a higher than specified grade is per- mitted. If the car is driven in adverse conditions,Volvo recommends using an oil of a higher gradethan the one specified.

Checking and filling with engine oil The oil level is detected with the electronic oil level sensor.
Filler pipe8
.
In some cases, oil may need to be topped up between service intervals. Action with regard to engine oil level does not need to be taken until a message is shown in thedriver display.
WARNING
If this symbol is shown together with the message Engine oil level
Service required, visit a workshop
- an authorised Volvo workshop is
recommended. The oil level may be too high.
IMPORTANT
If this symbol is shown together with a message about low oil level, such as
Engine oil level low
Refill 1 litre for example, then only
fill the volume specified, e.g. 1 litre.
WARNING
Do not spill oil onto the hot exhaust manifold due to the risk of fire.
Check the oil level
1. Open the Car status app from the app view
in the centre display.
2. Press the
Status button to show the oil
level.
Graphics for oil level in the centre display.
The oil level is checked using the electronic oil level gauge in the centre display when the engineis switched off.
NOTE
The system cannot directly detect changes when the oil is filled or drained. The car musthave been driven approx. 30 km and havebeen stationary for 5 minutes with the engineswitched off and on level ground before theoil level indication is correct.
8 Engines with electronic oil level sensor do not have a dipstick.
