trajectory lines and fields
The Park Assist Camera system uses trajectory lines and fields to indicate the vehicle's positionin relation to its immediate surroundings.
Trajectory lines
Sample guidelines
The trajectory lines are intended to show the position of the vehicle's outermost dimensionsbased on the current position of the steeringwheel to help simplify parallel parking, backinginto tight spaces or when attaching a trailer. The lines on the screen are projected as if they were a path on the ground around the vehicleand are directly affected by the way in which thesteering wheel is turned. This enables the driverto see path the vehicle will take, even if he/sheturns the steering wheel. These lines also indicate the outermost limits thatany object (door mirrors, corners of the body, atrailer hitch, etc.) extends out from the vehicle,even when it turns.
NOTE
When backing up with a trailer, the trajectory lines show the path that the
vehicle will take,
not the trailer. Trajectory lines will not be displayed while zooming in.
WARNING
Keep in mind that when the rear camera has been selected, the image on the screen onlyshows the area behind the vehicle. The drivermust always watch for people, animals, othervehicles, etc., near the sides or the front of thevehicle when turning while backing up. The opposite is true when the front camera is selected. Please note that the trajectory lines show the shortest path. Be sure that the vehicle

Location of the cameras and their fields of vision (generic illustration)
On models with the 360° panorama camera sys- tem, trajectory lines will be shown behind, in frontof or to the sides of the vehicle, depending on itsdirection.
• When driving forward: front lines
• When backing up: side/rear lines
When the front or rear camera is selected, trajec-tory lines will be shown regardless of the vehi-cle's direction. If a side camera is selected, trajectory lines will only be shown if the vehicle is backing up.
Trajectory lines for a trailer hitch (towbar)

Perpendicular parking
Procedure for perpendicular parking
PAP helps park the vehicle as follows:
1. The system searches for and measures a
possible parking space. While this is being done, the vehicle's speed may not exceedapprox. 4 mph ( 7 km/h).
2. The vehicle is steered while it is backing into the parking space and its position in thespace is adjusted by prompting the driver to select D or R while the system steers. The
driver has to control the vehicle's speed.
NOTE
PAP's Park out function cannot be used to
help a vehicle leave a parking space if the
Perpendicular parking function was used
to park the vehicle.
WARNING
• PAP does not function in all situations and is only intended to assist the driverduring parallel or perpendicular parking.
• As the driver, you have full responsibilityfor parking the vehicle in a safe manner.

Using Park Assist Pilot (PAP) *
Park Assist Pilot (PAP) gives the driver instruc- tions during the parking procedure. The functioncan also assist when leaving a parking space.
NOTE
While PAP is active, the driver's task is to:
• carefully monitor the area around the vehicle
• follow the instructions provided in thecenter display
• select a gear (
D or R) when prompted
• regulate the vehicle's speed
• apply the brakes when necessary andstop the vehicle
Symbols, images and text in the center display indicate when the various steps in the parkingprocedure will be carried out. PAP can be activated if the following conditions are met after the engine has started:
• The vehicle may not be towing a trailer.
• The vehicle's speed must be below approx.20 mph (30 km/h).
• The distance between the vehicle and aparking space must be between 1.6-5.0 ft(0.5-1.5 m)

NOTE
If a trailer hitch is configured in the vehicle's electrical system, PAP will take the trailerhitch into consideration when determining thenecessary size of a parking space.
ParkingProcedure for parking:
1. The system searches for and measures apossible parking space.
2. The vehicle is steered while it is backing into the parking space.
3. The vehicle's position is adjusted in the park- ing space by moving forward and rearward.
1: Searching and measuring
Parallel parking
Perpendicular parking
PAP searches for a potential parking space and measures it to see if there is sufficient space foryour vehicle. To start this procedure:
1. Tap the
Park In button in
the center display's Function view. If necessary, slow down to:
• a speed below 20 mph (30 km/h) for parallel parking
• approx. 12 mph ( 20 km/h) for perpendicularparking. 2. Keep an eye on the display and be prepared
to stop the vehicle when you are instructedby PAP to do so.
3. Select
Parallel parking or Perpendicular
parking and put the transmission in reverse.
4. Keep an eye on the display and be prepared to stop the vehicle when you are instructed by PAP to do so.
5. Stop the vehicle when instructed to do so.
NOTE
PAP normally searches for available parking spaces along the curb on the right (passeng-er's) side of the vehicle. However, it can alsoassist in finding and parking in spaces on thedriver's side. To do so:
• Activate the left turn signal. PAP will thensearch for a parking space on the leftside of the vehicle.

HDC is activated along with Low Speed Control (LSC), which together make driving on slipperysurfaces at low speeds easier. When HDC and LSC are activated, this changes the response from the accelerator pedal andengine.
Activating HDCThis function can be activated in different ways,depending on how the vehicle is equipped.
Select the Off Road drive mode to activate the
function. Select a different drive mode to turn HDC off. If this is done while the vehicle is on a steep down-grade, engine braking will decrease gradually.

Low Speed Control (LSC) Low Speed Control (LSC) helps make off-road driving easier on slippery surfaces when towinga trailer on grass, etc. This feature is part of the
Off Road drive mode.
When driving at low speeds, LSC prioritizes low gears and all wheel drive to help avoid wheelspin and to improve traction on slippery surfa-ces. The accelerator pedal and engine react dif-ferently to make low-speed driving easier.
LSC is activated along with the Off Road drive
mode. It is activated along with Hill Descent Control (HDC), which increases engine braking to helpkeep vehicle speed low and smooth, even drivingdown steep hills.

Driving through standing water
The vehicle should be driven with extreme cau- tion if it is necessary to drive through standingwater.
The vehicle can be driven through water up to a depth approximately level with the floor at walk-ing speed to help prevent water from enteringthe differential and/or the transmission or dam-aging electrical components. • If possible, check the depth of the water at its deepest point before driving through it.Take particular care when driving throughflowing water.
• Before driving through water, always select the
Off Road drive mode to ensure that the
gasoline engine is running and to maximize ground clearance.
• After driving through water, apply the brakesand check that they are functioning correctly.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.
CAUTION
•Damage may occur to the engine, trans- mission, electrical components, etc. if thevehicle is driven through water higherthan its floor level. Be aware that wavescreated by other vehicles could cause thelevel to temporarily be above the vehicle'sfloor level.
• Damage to any components due to waterabove the floor level, vapor lock or insuffi-cient oil is not covered under warranty.
• If the engine has been stopped while thevehicle is in water, do not attempt torestart it. Have the vehicle towed out ofthe water and inspected by a trained andqualified Volvo service technician.
WARNING
•Avoid driving through standing or rushing water. Doing so can be dangerous and itmay also be difficult to determine theactual depth of the water.
• If water cannot be avoided, after drivingthrough the water, press lightly on thebrake pedal to ensure that the brakes arefunctioning normally. Water or mud canmake the brake linings slippery, resultingin delayed braking effect.
