City Safety limitations
City Safety ™ may have limited or reduced func-
tionality in certain situations.
The function has several limitations that the driver should be familiar with:
Low objects
Hanging objects, such as flags for overhanging loads or accessories such as auxiliary lights orfront protective grids that extend beyond theheight of the hood may limit City Safety's func-tion.
Slippery driving conditions
The extended braking distance on slippery roads may reduce City Safety's capacity to help avoid acollision. In situations of this type, the ABSbrakes and Electronic Stability Control will helpprovide braking power and stability.
Backlighting
Strong sunlight, reflections, extreme light con- trasts, the use of sunglasses, or if the driver is notlooking straight ahead may make the visual warn-ing signal in the windshield difficult to see.
Heat
If the temperature in the passenger compartment is very high, the camera and radar sensor may betemporarily turned off for approx. 15 minutesafter the engine has been started to protect theirelectronic components. When the temperaturehas cooled sufficiently, the camera and radarsensor will restart automatically. The visual warning signal may also be temporarilydisabled due to high passenger compartmenttemperatures caused by strong sunlight. Warnings may not be given if the distance to the vehicle ahead is short and the driver is activelyoperating the vehicle (clearly depressing a pedalor turning the steering wheel).
Reduced visibility
City Safety's functions may be greatly impeded or deactivated by e.g., intense snowfall or rain, indense fog, in very dusty conditions or if there isblowing snow in front of the vehicle. Condensa-tion, ice, snow or dirt on the windshield may alsoreduce the system's functionality.
NOTE
•
Keep the windshield in front of the radar sensor free of ice, snow, dirt, etc.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sensor.Keep the hood free of ice and snow.
• Do not mount or in any way attach any-thing on the windshield that couldobstruct the radar sensor.

The tone becomes constant when you are within approximately 1 ft (30 cm) of an object and theinnermost sensor field will be red. If there areobjects within this distance both behind and infront of the vehicle, the tone alternates betweenfront and rear speakers. 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 Setting menu.
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 thevehicle is approximately 1 ft (0.3 m). 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 (0.8 m). 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.

Park Assist Camera (PAC) *
limitations
The Park Assist Camera system has certain limi- tations that the driver should be aware of.
NOTE
Bicycle carriers or other accessories mounted on the tailgate may obstruct the camera'sfield of vision.
Blind sectorsEven if a fairly small section of the screen image appears to be obstructed, this may mean that arelatively large area is hidden and objects theremay not be detected until they are very near thevehicle.
The "blind" sectors between the cameras' fields of vision
• With 360° view selected, objects/obstacles
may not be detected at the edges of the indi- vidual cameras' fields of vision.
• A crossed-out camera icon means that thecamera is not functioning properly.
Ambient lightingThe camera images are adjusted automatically to the ambient light, which means the image mayvary slightly in terms of light and quality. Poorambient lighting may reduce the quality of theimage.
Maintenance
• Keep the camera's lens free of dirt, ice and snow. This is particularly important in poorambient lighting conditions.
• Remove dirt, ice and snow carefully to avoidscratching the lenses.
• Clean the lens regularly with warm water anda suitable car washing detergent.

Park Assist Pilot (PAP) *
Park Assist Pilot (PAP) helps the driver drive into and leave parallel parking spaces.
Park Assist Pilot (PAP) provides assistance when parking by measuring the parking space andturning the steering wheel to guide the vehicleinto the space. Information about the actions required by the driver is provided in the center display in the formof symbols, images and text.
NOTE
The driver's task is to follow the instructions, select a gear ( D or R), regulate the vehicle's
speed, apply the brakes when necessary and stop.

320 adjusted by driving slightly forward and backing up. 1.
Put the gear selector in D, wait until the
steering wheel has turned and drive forward slowly.
2. Stop the vehicle when you are instructed by PAP to do so.
3. Put the gear selector in R, back up slowly
and stop when you are instructed by PAP todo so.
When the parking procedure is finished (this will be 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 is using the sensors than when Park Assist isusing them.
Leaving a parking spaceThis function can only be used for a vehicle that has been par-allel parked and is activated inthe center display's Functionview. 1. Tap the
Park out button in
the center display's Function view.
2. Follow the instructions provided. The proce- dure is the same as when parking the vehicle. The steering wheel may turn back slightly when the function is completed and the driver mayhave to turn the back before leaving the parkingspace. If PAP determines that the driver can leave the parking space without assistance, the functionwill deactivate before the vehicle is completelyout of the space.

The PAP function may be limited in certain situa- tions.
The PAP parking sequence is cancelledA parking sequence will be cancelled:
• if the vehicle is driven too fast (above approx. 4 mph (7 km/h)
• if the driver taps
Cancel in the center display
• if the driver moves the steering wheel with sufficient force.
• if the anti-lock brakes or Electronic StabilityControl are activated (e.g., if a wheel beginsto spin or lose traction)
In such cases, a text message will explain why the parking sequence was cancelled.
NOTE
• PAP will not function correctly if its sen- sors are obstructed by dirt, snow, etc.
• In certain situations, PAP may not be ableto measure a parking space. This couldbe due to external sources of sound (e.g.,a vehicle's horn, tires on wet asphalt,pneumatic brakes, noise from a motorcy-cle's exhaust, etc.) emitting ultrasoundusing approximately the same frequen-cies as PAP.

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 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.
WARNING
If vehicle does not have electrical current and both the electric motor and gasoline engineare switched off, the brakes cannot be usedto 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 is carrying a heavy load, using brake mode B to augment the brakes or the
Off Road* drive mode can also be used 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.
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 the gear selector from P.
In certain cases, a message may appear in the instrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.
Light braking charges the hybrid batteryWhen 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 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 control
Auto-hold control and indicator light
Turn Auto-hold on or off by pressing the control in the tunnel console. The indicator light illumi-nates when the function is on. When Auto-hold is off, Hill Start Assist (HSA) willbe activated to help prevent the vehicle from roll-ing backwards when starting up a hill.

Brake assist system
The Brake Assist System (BAS) increases brak- ing force, thereby helping reduce braking dis-tance. The system monitors the driver's braking habits and increases braking force when necessary.Brake force can be increased up to the point atwhich the ABS system is activated. The functionis deactivated when pressure on the brake pedaldecreases.

Braking effect after a collisionIn certain types of collisions, the vehicle's brakes are applied to help prevent or mitigate a secon-dary collision.
Maintaining control of the vehicle after a collision may 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 will be 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 not be desirable, the driver can override this systemby pressing the accelerator pedal. This feature can only function if the brake system is intact after the collision.

Emergency brake lights
The emergency brake lights activate in the event of 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 engine brake 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 drive
mode.
HDC is particularly useful when driving down steep hills with rough surfaces, and where theroad may have slippery patches.
WARNING
HDC does not function in all situations, and is a supplementary braking aid. The driver hasfull responsibility for driving in a safe manner.
FunctionHDC allows the vehicle to roll forward or in reverse 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 the vehicle at any time. HDC is activated along with Low Speed Control (LSC), which together make driving on slipperysurfaces at low speeds easier.

Parking brake The electric parking brake helps to keep the vehicle stationary when it is parked.
Parking brake control in the tunnel console between the front seats
NOTE
•A faint sound from the parking brake's electric motor can be heard when theparking brake is being applied. Thissound can also be heard during the auto-matic function check of the parkingbrake.
• The brake pedal will move slightly whenthe electric parking brake is applied orreleased.
If the vehicle is not moving when the parking brake is applied, only the rear wheels are affec- ted. If it is applied while the vehicle is moving, thenormal brakes are used on all four wheels. Thebrakes will only be applied on the rear wheelsonce the vehicle has stopped.

Before a long distance trip
It is always worthwhile to have your vehicle checked 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 be checked before any long trip:
• Check that engine runs smoothly and that fuel 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 by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Driving economically with the XC90 T8Twin Engine Plug-in Hybrid
Plan your driving in order to utilize the electric motor as much as possible. An energy-conserving driving style lowers current consumption from the hybrid battery and helpsincrease electric driving range.
Charging
• Charge the hybrid battery regularly using the charging cable. Whenever possible, begin adrive with a fully charged battery.
• Check the location of charging points.
• Where possible, choose parking spaces withcharging points.
