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.

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.

Parking with Active parking assistance *
The Active parking assistance (Park Assist Pilot - PAP) helps the driver park in three steps. Thefunction can also help the driver to leave a park-ing space.
NOTE
The PAP function measures the space and steers the car - the driver's task is to:
• keep a close watch around the car
• follow the instructions in the centre dis-play
• change gear (reverse/forward)
• control and maintain a safe speed
• brake and stop.
PAP can be activated if the following criteria are met once the engine has been started:
• No trailer is attached to the car.
• Speed must be lower than 30 km/h(20 mph).
NOTE
The distance between the car and parking spaces should be 0.5-1.5 metres while PAPis searching for a parking space.
ParkingThe PAP function parks the car using the follow- ing steps:
1. A parking space is identified and measured.
2. The car is reversed into the space.
3. The car is positioned into the space - the
system may then request that the driver changes gear.
Finding and measuring parking spaces
The function can be activated in the centre display's functionview. It can also be accessed from the camera views.
Principle for parallel parking.
Principle for perpendicular parking.
1. Drive no faster than 30 km/h (20 mph) forparallel parking or 20 km/h (12 mph) for perpendicular parking.
2. Tap on the
Park In button in function view.
> PAP searches for a parking space and checks whether it is big enough.
3. Keep an eye on the centre display - be ready to stop the car when the graphic and mes- sage indicate that a suitable parking spacehas been found.
> A pop-up window is shown.
4. Select
Parallel parking or Perpendicular
parking and select reverse gear.

Parking on a hill
WARNING
Always use the parking brake when parking on an inclined surface. Engaging a gear or the automatic transmission's P position is not suf-
ficient to hold the car stationary in all situa- tions.
If the car is parked facing uphill: • Turn the wheels
away from the kerb.
If the car is parked facing downhill:
• Turn the wheels
towards the kerb.
Heavy load uphill
A heavy load, such as a trailer, can cause the car to roll backward when the parking brake isreleased automatically on a steep incline. Avoid this by pulling the control upwards while drivingthe car away. Release the control when theengine achieves traction.
Settings for parking brake
Automatic activation of the parking brake isselected via the centre display. Automatic activation when the car is switched off:1.

In the event of a fault in the parking brake
Contact an authorised Volvo workshop if it is not possible to release or apply the parking brakeafter several attempts.
An acoustic warning signal sounds when driving with the parking brake applied. If the car has to be parked before a possible fault is rectified then the wheels must be turned as ifparking on a hill and the gear selector must be in position P, or engage first gear if the car has a
manual gearbox.
Low battery voltageIf the battery voltage is too low then the parking brake can neither be released nor applied. Con-nect a donor battery if the battery voltage is toolow.
Replacing the brake liningsThe rear brake linings must be replaced at aworkshop due to the design of the electrically-operated parking brake - an authorised Volvoworkshop is recommended.

Driving in water Driving in water means that the car is driven through deep water on a water-covered road-way. Driving in water must be carried out withgreat caution.
The car can be driven through water at a maxi- mum depth of 25 cm at a maximum speed ofwalking pace. Extra caution should be exercisedwhen passing through flowing water. During driving in water, maintain a low speed and do not stop the car. When the water has beenpassed, depress the brake pedal lightly andcheck that full brake function is achieved. Waterand mud for example can make the brake liningswet resulting in delayed brake function.
• If necessary, clean the contacts for the elec-tric heater and trailer coupling after driving inwater and mud.
• Do not let the car stand with water over thesills for any long period of time - this couldcause electrical malfunctions.

Overloading the starter battery
The electrical functions in the car load the starter battery to varying degrees. Avoid using the igni-tion position II when the car is switched off.
Instead, use ignition position I - which uses less
power.
Also, be aware of different accessories that load the electrical system. Do not use functions whichuse a lot of power when the car is switched off.Examples of such functions are:
• ventilation fan
• headlamps
• windscreen wiper
• audio system (high volume).
If the starter battery voltage is low, the message
12 V Battery Low charge, will soon enter
power save mode is shown in the driver display.
The energy-saving function then shuts down cer- tain functions or reduces certain functions suchas the ventilation fan and/or audio system.
–In which case, charge the starter battery by starting the car and then running it for atleast 15 minutes - starter battery charging ismore effective during driving than runningthe engine at idling speed while stationary.

Preparations for a long trip
Before a driving holiday or some other type of long journey, it is important to check the car'sfunctions and equipment particularly carefully.
Check that:
• the engine is working normally and that fuel consumption is normal
• there are no leaks (fuel, oil or other fluid)
• all bulbs are working
• the tyres have sufficient tread depth andpressure
• a warning triangle and high-visibility vest arelocated in the car - legally required in certaincountries
• the wiper blades are in good condition.

Winter driving
For winter driving it is important to perform cer- tain checks of the car in order to ensure that itcan be driven safely.
Check the following in particular before the cold season:
• The engine coolant must contain 50% glycol.This mixture protects the engine againstfrost erosion down to approximately –35 °C.To avoid health risks, different types of glycolmust not be mixed.
• The fuel tank must be kept filled to preventcondensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate startingin cold weather and also reduce fuel con-sumption while the engine is cold. Readmore about suitable oils in the section"Adverse driving conditions for engine oil".
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
• The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reduced by thecold.
• Use washer fluid with antifreeze to avoid iceforming in the washer fluid reservoir.
Slippery driving conditionsTo achieve optimum roadholding Volvo recom-mends using winter tyres on all wheels if there isa risk of snow or ice.
NOTE
The use of winter tyres is a legal requirement in certain countries. Studded tyres are notpermitted in all countries.
Practise driving on slippery surfaces under con- trolled conditions to learn how the car reacts.
