Park Assist *
The Park Assist system is designed to assist you
when driving into parking spaces, garages, etc. An audible signal and symbols in the instrumentpanel and center display indicate the distance tothe object.
Display view showing object zones and sensor sectors
The center display shows an overview of the vehi- cle in relation to objects that have been detected. The highlighted sector shows which of the sen- sors has detected the object. The closer thehighlighted sector is to the vehicle symbol, thecloser the actual object is to your vehicle. The Park Assist system uses an intermittent tone that pulses faster as you come closer to anobject. Sound from the infotainment system willbe temporarily turned down. The audible signals for objects in front of and tothe sides are active while the vehicle is movingand will stop after the vehicle has been stoppedfor approx. 2 seconds. The audible signals forobjects behind the vehicle are active even whenthe vehicle has stopped moving. The audible signal becomes constant when you are within approximately 1 ft (30 cm) of an objectand the highlighted sensor field is filled in. While an audible signal is being given, its volume level can be raised/lowered using the
>II control
in the center console or can be adjusted in the center displays Top view under
Settings.
NOTE
Audible alerts will only be provided for objects that are directly in the vehicle's path.
WARNING
Park Assist is an information system, NOT a safety system. This system is designed to bea supplementary aid when parking the vehicle.It is not, however, intended to replace the driv-er's attention and judgement.
Rear park assist
The system's rear sensors are activated automat- ically when the engine is started and are active ifthe vehicle rolls rearward with the gear selector in N or if R has been selected.
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The rear sensors will be deactivated automatically when towing a trailer if Volvo genuine trailer wir-ing is used. If a non-Volvo trailer hitch is beingused, it may be necessary to switch off the sys-tem manually.

Side park assist
The system's side sensors are activated automat- ically when the engine is started and are active atspeeds below approximately 6 mph (10 km/h). The distance monitored along the sides of the vehicle is approximately 1 ft (30 cm). The audiblesignal comes from the side speakers.
Front park assist
The system's front sensors are activated auto- matically when the engine is started and areactive at speeds below approximately 6 mph(10 km/h). The distance monitored in front of the vehicle is approximately 2.5 ft (80 cm). The audible signalcomes from the front speakers. Front Park Assist is deactivated if the parking brake is applied or if the gear selector is put in P.
When installing auxiliary headlights, be sure that they do not obstruct the front sensors. Otherwise,these lights could trigger a Park Assist warning.

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)

STARTING AND DRIVING
* Option/accessory.

Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles * and the fuel-
conserving start/stop function.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function. The power brakes only function when the engine is running. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels stifferthan usual. When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle iscarrying a heavy load, manual gear shifting canbe used for engine braking to augment the brakes. Use the
Off Road*
drive mode on steep
downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Driving on wet or salted roadsProlonged driving on wet or salted roads can affect brake function and increase stopping dis-tance. Be sure to keep a safe distance to thevehicle ahead when driving under these condi-tions.
Brake pad inspection
On vehicles equipped with a jack *, the condition
of the brake pads can be checked by raising thevehicle and performing a visual inspection of thebrake pads.
WARNING
• If the vehicle has been driven immediately prior to a brake pad inspection, the wheelhub, brake components, etc., will be veryhot. Allow time for these components tocool before carrying out the inspection.
• Apply the parking brake and put the gear selector in the Park (
P) position.
• Block the wheels standing on the ground, use rigid wooden blocks or large stones.
WARNING
•
Use the jack intended for the vehicle when changing a tire. For any other job,use stands to support the vehicle.
• The jack should be kept well-greased andclean, and should not be damaged.
• Be sure the jack is on a firm, level, non-slippery surface.
• No objects should be placed between thebase of jack and the ground, or betweenthe jack and the attachment bar on thevehicle.
• The jack must correctly engage the jackattachment.
• Never allow any part of your body to beextended under a vehicle supported by ajack.

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control

Auto-hold brake function
With the Auto-hold brake function, the driver can release the brake pedal and the brakes willremain applied, for example, when the vehiclehas stopped at a traffic light or intersection.
When the vehicle is no longer moving forward, Auto-hold applies the brakes automatically, eitherusing the normal brakes or the parking brake.The brakes will be released when the acceleratorpedal is depressed. If the driver's door is opened or the engine is turned off, the parking brake will be applied auto-matically. Auto-hold is deactivated when the transmission is in neutral or if the driver's door is open and theseat belt is unbuckled.
