Park Assist*
Parking assistance assists the driver when manoeuvring in tight spaces by indicating thedistance to obstacles by acoustic signals com-bined with graphics on the centre display.
Screen view showing obstacle zones and sensor sectors.
The centre display shows an overview of the rela- tionship between the car and detected obstacles. The highlighted sector indicates the location of the obstacle. The closer the car symbol is to ahighlighted sector box, the shorter the distancebetween the car and detected obstacle. The shorter the distance to the obstacle, the faster the signal sounds. Other sound from theaudio system is muted automatically. The acoustic signal for obstacles ahead and to the sides is active when the car is moving butstops after the car has been stationary for approx. 2 seconds. The acoustic signal for obsta-cles behind is also active when the car is station-ary. At a distance within 30 cm from an obstacle behind or in front of the car, the tone is constantand the active sensor's field closest to the carsymbol is filled. The volume of the parking assistance signal can be adjusted while the signal is sounding by means of the [
>II] knob on the centre console.
Adjustment can also be performed in the top view's
Settings menu option.
NOTE
• Acoustic warnings are only given for objects directly on the vehicle's route.
WARNING
•Parking assistance does not relinquish the driver's own responsibility duringparking.
• The sensors have blind spots whereobstacles cannot be detected.
• Be aware of e.g. people or animals nearthe car.
Backwards
NOTE: The illustration is schematic - details may vary depending on car model.
The sensors for reverse are activated if the car rolls backward without a gear engaged or whenthe gear lever is moved to reverse position. The measuring range starts approx. 1.5 metres behind the car. When reversing with a hitched trailer, parking assistance backward is deactivated automatically.
NOTE
When reversing with e.g. a trailer or bike car- rier on the towbar - without Volvo genuinetrailer wiring - parking assistance may need tobe switched off manually in order that thesensors do not react to them.

Limitations of Parking assistance *
The Parking assistance function may have limita- tions in certain situations.
NOTE
Since a towbar is configured with the car's electrical system, towbar protrusion isincluded when the function measures the dis-tance to an object behind the car.
IMPORTANT
Objects e.g. chains, thin glossy poles or low barriers may be in the "signal shadow" andare then temporarily not detected by the sen-sors - the pulsating tone may then unexpect-edly stop instead of changing over to theexpected constant tone. The sensors cannot detect high objects, such as projecting loading docks.
• In such situations, pay extra attention andmanoeuvre/reposition the car particularlyslowly or stop the current parkingmanoeuvre - there may be a high risk ofdamage to vehicles or other objects sinceinformation from the sensors is notalways reliable in such situations.
IMPORTANT
In certain conditions the parking assistance system may produce incorrect warning sig-nals that are caused by external soundsources that emit the same ultrasonic fre-quencies that the system works with. Examples of such sources include horns, wet tyres on asphalt, pneumatic brakes andexhaust noises from motorcycles, etc.
Maintenance
Location of the parking sensors 24
.
For parking assistance to work optimally, the parking assistance sensors must be cleaned reg-ularly with water and car shampoo.

Backwards
The backwards-facing camera 27
is fitted above the reg-
istration plate.
The backward-facing camera shows a wide area behind the car. For certain models, part of thebumper can be seen as well as the towbar insome cases. Objects shown in the centre display may appear slightly tilted — this is normal.
NOTE
Objects on the centre display may be closer to the car than they appear to be on thescreen.
Forwards
The forwards parking camera 27
is located in the grille.
The front camera can be helpful on an exit road with limited visibility to the sides, e.g. when thereare high hedges. It is active at speeds up to25 km/h (16 mph) - following which, the frontcamera is switched off. If the car does not reach 50 km/h (30 mph), and the speed falls below 22 km/h (14 mph) within60 seconds after the forward-facing camera hasbeen switched off, the camera is reactivated.
NOTE
Automatic reactivation of the front camera on speed reduction requires that Auto Camera
Reverse Activation is selected in Settings
My CarPark Assist.
The sides
The side cameras 27
are positioned in each door mirror.
The side cameras show what is along each side of the car.

Park assist lines and fields for the Park Assist Camera *
The Park Assist Camera indicates the position of the car in relation to its surroundings by display-ing lines on the camera image.
Park assist lines
Examples of how the park assist lines can be displayed for the driver.
Park assist lines show the intended route for the car's external dimensions with the current steer-ing wheel angle - this facilitates parallel parking,reversing into tight spaces and when connectinga trailer. The lines on the screen are projected as if they were at ground level behind the car and responddirectly to steering wheel movements, showingthe driver the path the car will take - also whenthe car is turning. These park assist lines include the car's mostprotruding parts, e.g. towbar, door mirrors andcorners.
NOTE
Park assist lines are not shown when zoom- ing in.
NOTE
•
When reversing with a trailer which is not connected electrically to the car, the lines on the display show the route the
car will
take - not the trailer.
• The screen shows no lines when a trailer is connected electrically to the car's elec-trical system.
IMPORTANT
Remember that when rear camera view is selected, the centre display only shows thearea behind the car. Keep an eye on the sidesand front of the car when turning the steeringwheel while reversing. The same applies vice versa - note what hap- pens to the rear parts of the car when thefront camera view is selected. Note that the guide lines show the
shortest
route. Therefore, pay extra attention to the car's sides so that they do not go against/over something when the steering wheel isturned when driving forward or that the frontsweeps against/over something when thesteering wheel is turned when reversing.

Driving with a trailer
When driving with a trailer, there are a number of points that are important to think about regar-ding the towing bracket, the trailer and how theload is positioned in the trailer.
Payload depends on the car's kerb weight. The total of the weight of the passengers and allaccessories, e.g. towbar, reduces the car's pay-load by a corresponding weight. The car is supplied with the necessary equipment for towing a trailer.
• The car's towing bracket must be of anapproved type.
• Distribute the load on the trailer so that theweight on the towing bracket complies withthe specified maximum towball load. Towballload is calculated as part of the car's payload.
• Increase the tyre pressure to the recom-mended pressure for a full load. For moreinformation on tyre pressure, see the section"Approved tyre pressures".
• The engine is loaded more heavily than usualwhen driving with a trailer.
• Do not tow a heavy trailer when the car isbrand new. Wait until it has been driven atleast 1000 km.
• The brakes are loaded much more than usualon long and steep downhill slopes. Downshiftto a lower gear and adjust your speed. •
Follow the regulations in force for the permit-ted speeds and weights.
• Maintain a low speed when driving with atrailer up long, steep ascents.
• The maximum trailer weights given only applyto altitudes up to 1000 metres above sealevel. At higher altitudes, engine power andthus the car's climbing ability is decreaseddue to the reduced air density, and the maxi-mum trailer weight must therefore bereduced. The weight of the car and trailermust be decreased by 10 % for each addi-tional 1000 m (or part thereof).
• Avoid driving with a trailer on inclines of morethan 12%.
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combina-tion with fuel quality are factors that consider-ably increase the car's fuel consumption.
Trailer connectorAn adapter is required if the car's towing bracket has a 13 pin connector and the trailer has a 7 pinconnector. Use an adapter approved by Volvo.Make sure the cable does not drag on theground.
IMPORTANT
When the engine is switched off, the constant battery voltage to the trailer connector can beswitched off automatically so as not to drainthe starter battery.
Trailer weightsInformation about Volvo's permitted trailer weights is available in the article "Towingcapacity and towball load".
WARNING
Follow the stated recommendations for trailer weights. Otherwise, the car and trailer may bedifficult to control in the event of suddenmovement and braking.
NOTE
The stated maximum permitted trailer weights are those permitted by Volvo. National vehicleregulations can further limit trailer weightsand speeds. Towbars can be certified forhigher towing weights than the car canactually tow.
Direction indicators and brake lights on the trailer
If one or more of the trailer's direction indicators or brake light bulbs is broken, the driver display
