Park Assist*
The Park Assist system is designed to assist youwhen 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 tonethat 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 youare within approximately 1 ft (30 cm) of an objectand the highlighted sensor field is filled in.
While an audible signal is being given, its volumelevel can be raised/lowered using the >II controlin the center console or can be adjusted in thecenter displays Top view under Settings.

NOTE
Audible alerts will only be provided for objectsthat are directly in the vehicle's path.

WARNING
Park Assist is an information system, NOT asafety 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 selectorin N or if R has been selected.
The distance monitored behind the vehicle isapproximately 5 ft (1.5 m). The audible signalcomes from the rear speakers.
The rear sensors will be deactivated automaticallywhen 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.

Backing up
Location of the rear Park Assist Camera (generic illus-tration)
The rear camera shows a wide area behind thevehicle and on certain models, part of the bumperand the trailer hitch (if installed) will be visible.
Some objects on the screen may appear to “lean”slightly, which is normal.

WARNING
People/objects/obstructions displayed on thecenter console screen may be closer to thevehicle than they appear.
Front camera
Location of the front Park Assist Camera (generic illus-tration)
The front camera is located behind the grill andcan be useful when driving off in areas with lim-ited visibility (hedges, bushes, etc). It is active atspeeds up to approx. 16 mph (25 km/h) and isautomatically turned off when the vehicleexceeds this speed.
However, if the vehicle's speed does not exceed30 mph (50 km/h) and its speed goes under14 mph (22 km/h) within 60 seconds after thecamera has been switched off, the front camerawill reactivate.

When the vehicle is backing up, PAP will steer itinto the parking space. Do as follows:
1.Check that the area behind the vehicle isclear and put the gear selector in R.
2. Back up slowly without moving the steeringwheel. The vehicle's speed must be belowapproximately 4 mph (7 km/h).
3. Keep an eye on the instrument panel and beprepared to stop the vehicle when you areinstructed by PAP to do so.

NOTE
•Release the wheel while PAP is steeringthe vehicle.
•The steering wheel must be able to turnfreely.
•For PAP to function optimally, wait untilthe steering wheel is no longer turningbefore beginning the next phase of theparking procedure.
3: Adjusting the vehicle's position
Parallel
Perpendicular
After the vehicle has backed into the parkingspace, its position in the space has to be
adjusted by driving slightly forward and backingup.
1.Put the gear selector in D, wait until thesteering wheel has turned and drive forwardslowly.
2.Stop the vehicle when you are instructed byPAP to do so.
3.Put the gear selector in R, back up slowlyand stop when you are instructed by PAP todo so.
When the parking procedure is finished (this willbe indicated by a text message and a graphicimage), PAP switches off automatically. If neces-sary, the driver may need to make minor adjust-ments to ensure that the vehicle is parked cor-rectly.

CAUTION
The warning distance is shorter when PAP isusing the sensors than when Park Assist isusing them.

Leaving a parking space
This function can only be usedfor a vehicle that has been par-allel parked and is activated inthe center display's Functionview.

STARTING AND DRIVING
* Option/accessory, for more information, see Introduction.376
Starting and driving
The vehicle is equipped with an automatic trans-mission that also makes it possible to shift gearsmanually.
Certain functions can also be used when theengine 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 system
If 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 fartherthan normal and requires greater foot pressure,the stopping distance will be longer.
Pressure on the brake pedal is enhanced by thepower braking function.

WARNING
If the vehicle does not have electrical currentand both the electric motor and gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
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, using brake mode B toaugment the brakes or the Off Road* drive
mode can also be used on steep downgrades toincrease 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 somevibration in the brake pedal, which is normal.
The system performs a brief self-diagnostic testwhen 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.

Function check when the engine is
started
A Plug-in Hybrid is equipped with a "brake bywire" brake system. A function check is per-formed each time the engine is started and thedriver depresses the brake pedal to move thegear selector from P.
In certain cases, a message may appear in theinstrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.

Light braking charges the hybrid battery
When the brakes are applied lightly, the electricmotor's braking function is used, which converts

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 parkingbrake, 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*

Braking effect after a collision
In certain types of collisions, the vehicle's brakesare applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collisionmay be difficult. To help avoid or mitigate theeffect of a secondary collision, the brakes areapplied automatically to help bring the vehicle toa stop.
The brake lights and hazard warning flashers willbe activated and the flashers will remain on afterthe vehicle has come to a standstill. The parkingbrake will then be applied automatically.
In a situation where stopping the vehicle may notbe desirable, the driver can override this systemby pressing the accelerator pedal.
This feature can only function if the brake systemis intact after the collision.

•Airbag system (p. 71)
•Rear Collision Warning (RCW) (p. 338)
Emergency brake lights
The emergency brake lights activate in the eventof hard braking/rapid deceleration at most nor-mal driving speeds or if the ABS system is acti-vated. This function causes an additional taillighton each side of the vehicle to illuminate to helpalert vehicles traveling behind.
Once the emergency brake lights have been acti-vated, if the driver releases the brake pedal, thebrake lights will return to their normal function.

Hill Descent Control (HDC)
HDC is a type of low-speed automatic enginebrake and makes it possible to increase ordecrease the vehicle's speed on steep downhillgradients using only the accelerator pedal, with-out applying the brakes.
HDC is integrated into the Off Road drivemode.
HDC is particularly useful when driving downsteep hills with rough surfaces, and where theroad may have slippery patches.

WARNING
HDC does not function in all situations, and isa supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.

Function
HDC allows the vehicle to roll forward or inreverse at very low speed with enhanced enginebraking. However, speed can be adjusted withthe accelerator pedal. When the acceleratorpedal is released, the vehicle will return to verylow speed.
The driver can use the brakes to slow or stop thevehicle at any time.
HDC is activated along with Low Speed Control(LSC), which together make driving on slipperysurfaces at low speeds easier.

Before a long distance trip
It is always worthwhile to have your vehiclechecked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should bechecked before any long trip:
•Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
•Before leaving on a trip, fill the fuel tank andmake sure the hybrid battery is fully charged.During the trip, make a habit of refueling reg-ularly.
•Check for fuel, oil, and fluid leakage.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully and replace thosethat are worn. Also, check tire inflation pres-sure.
•The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
•Check all lights, including high beams.
•Reflective warning triangles are legallyrequired in some states/provinces.
•Have a word with a trained and qualifiedVolvo service technician if you intend to drive
in countries where it may be difficult toobtain the correct fuel.
•Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained bythinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.

Driving economically with the XC90 T8
Twin Engine Plug-in Hybrid
Plan your driving in order to utilize the electricmotor as much as possible.
An energy-conserving driving style lowers currentconsumption from the hybrid battery and helpsincrease electric driving range.

Charging
•Charge the hybrid battery regularly using thecharging cable. Whenever possible, begin adrive with a fully charged battery.
•Check the location of charging points.
•Where possible, choose parking spaces withcharging points.
