WARNING
• Pedestrian and Cyclist Detection with Full Auto Brake will not provide awarning or brake the vehicle forpedestrians in darkness or in tunnels,even if there is street lighting in thearea.
• The auto-brake function can help pre-vent a collision or reduce the speed atimpact but the driver should alwaysapply the brakes for the best possiblebraking effect, even if auto-brake isactively applying the brakes.
• Never wait for a collision warning. Thissystem is designed to be a supple-mentary driving aid. It is not, however,intended to replace the driver's atten-tion and judgement. The driver isresponsible for maintaining a safe dis-tance and speed, even when the colli-sion warning system is in use.
• Maintenance of the Pedestrian andCyclist Detection with Full Auto Brakesystem's components must only beperformed by a trained and qualifiedVolvo technician.
Function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work together to detect a pedestrian, a cyclist, sta-tionary vehicles and vehicles that are movingin the same direction as your vehicle. If thereis a risk of collision with a vehicle, a cyclist ora pedestrian, the driver is alerted by a flash-ing red warning light and an audible warningsignal. The system is active at speeds above3 mph (4 km/h).
Brake SupportIf the risk of collision continues to increaseafter the collision warning has been given,Brake Support is activated. Brake Supportprepares the brake system to react quickly,and the brakes are applied slightly. This maybe experienced as a light tug. If the brakes are applied quickly, full braking effect will be provided. Brake Support alsoincreases brake force if the system deter-mines that the driver has not applied ade-quate pressure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver hasnot applied the brakes or begun to steeraround the vehicle, pedestrian or a cyclist,the auto-brake function is activated withoutthe driver pressing the brake pedal. Full brakeforce is applied to help reduce the vehicle’sspeed when the collision occurs or limitedbrake force is applied if this is sufficient toavoid the collision.
NOTE
The auto-brake and brake support func- tions are always on and cannot be turnedoff.

Warning distance.
The warning distance determines the level of sensitivity used by the system. The warning distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal.
WARNING
• The setting Short should only be used
in situations where traffic is light and moving at low speeds.
• Pedestrian and Cyclist Detection withFull Auto Brake alerts the driver to therisk of a collision but this function can-not reduce the driver’s reaction time.
• For the system to be as effective aspossible, it is recommended that Dis-tance Alert be set to 4 or 5, seepage 169.
NOTE
•When Adaptive Cruise Control is used, the warning light and signal will beused by that function, even if thewarnings provided by Pedestrian andCyclist Detection with Full Auto Brakehave been deactivated by the driver.
• In situations where traffic is moving atconsiderably different speeds, or if thevehicle ahead brakes suddenly, warn-ings may be considered to be late, even if the setting
Long has been
selected.
Checking settingsThe current system settings can be checked by pressing MY CAR on the center console

Maintenance
Camera and radar sensor 1
In order to function properly, the camera and radar sensor must be kept clean. Dirt, ice,snow, etc., will reduce the function of thesecomponents. Remove ice and snow when necessary and wash these areas regularly with a suitable carwashing liquid.
Limitations
Strong sunlight, reflections, extreme light contrasts, the use of sunglasses, or if thedriver is not looking straight ahead may makethe visual warning signal in the windshield dif-ficult to see. For this reason, always activatethe audible warning signal. Slippery driving conditions increase braking distance, which can reduce the system'scapacity to avoid a collision. In these condi-tions, the ABS and DSTC systems providethe best possible braking effect while helpingto maintain stability.
NOTE
The visual warning signal may be tempo- rarily disengaged in the event of high pas-senger compartment temperature due tostrong sunlight, etc. If this occurs, theaudible warning signal will be used, even ifit has been deactivated in the menu sys-tem.
WARNING
• In certain situations, the system can- not provide warnings or warnings maybe delayed if traffic conditions or otherexternal factors make it impossible forthe radar sensor or camera to detect apedestrian, a cyclist or a vehicleahead.
• Warnings may not be provided if thedistance to the vehicle ahead is short,or if movements of the steering wheel/brake pedal are great, such as duringactive driving.
• The sensor system has a limited rangefor pedestrians/cyclists and provideswarnings and braking effect mosteffectively at speeds up to 30 mph(50 km/h). For stationary or slow-mov-ing vehicles, the system functions bestif your vehicle’s speed is belowapproximately 45 mph (70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full Auto Brake system uses the same radar sen-sors as Adaptive Cruise Control. For more

WARNING
• The camera has the same limitations as the human eye. In other words, its“vision is impaired” by adverseweather conditions such as heavysnowfall, dense fog, etc. These condi-tions may reduce the function of sys-tems that depend on the camera orcause these systems to temporarilystop functioning.
• Never place any objects, decals, etc.,on the windshield in front of the cam-era. This could reduce or block thecamera’s function, and could causeone or more of the systems that utilizethe camera to stop functioning.
• Strong sunlight, reflections from theroad surface, ice or snow covering theroad, a dirty road surface, or unclearlane marker lines may drasticallyreduce the camera’s capacity todetect the side of a lane, a pedestrian,a cyclist or another vehicle.
Pedestrian detection
The system cannot identify all pedestrians
The Pedestrian and Cyclist Detection with Full Auto Brake system can only identify anddetect a pedestrian who is standing upright.This person can be standing still, walking orrunning. This means that the system has to be able to identify a person's head, arms, shoulders,legs, the upper and lower parts of the bodyand a person's pattern of movement whenwalking or running. If parts of the body are not visible to the cam- era, the system cannot detect the pedestrian. The following conditions apply:
• In order to detect a pedestrian, the sys- tem must have a full view of the person's entire body and the person must be atleast 32 in. (80 cm) tall.
• The system cannot detect a pedestriancarrying a large object.
• The camera's capacity to see a pedes-trian at dawn or dusk is limited, much asit is for the human eye.
• The camera's function is deactivated andwill not detect a pedestrian in darkness orin tunnels, even if there is street lighting inthe area.WARNING
• Pedestrian and Cyclist Detection with Full Auto Brake is designed to be asupplementary driving aid. It is not,however, intended to replace the driv-er's attention and judgement. Thedriver is always responsible for operat-ing the vehicle in a safe manner.
• The system cannot detect all pedes-trians in all situations, such as in dark-ness/at night and cannot detect parti-ally hidden pedestrians, people whoare less than approx. 32 in. (80 cm)tall, or people wearing clothing thatobscures the contours of their bodies.

Cyclist detection
Optimal example of what the system considers to be a cyclist: clear body/bike contours, straightfrom behind and directly in front of the vehicle
In order to help detect a cyclist, the system has to receive clear information about thecontours of the cyclist's body and the bike. Ithas to able to clearly detect the bike, thecyclist's head, arms, shoulders, legs andupper and lower body combined with the per-son's pattern of movement when cycling.
The function only detects cyclists from behind who are moving in the same direction as yourvehicle
The Cyclist Detection feature requires the fol- lowing in order to function: • The cyclist must be an adult riding an "adult-size" bike
• The bike must be equipped with anapproved and clearly visible rear-facingred reflector that is mounted at least27 in. (70 cm) above the road surface
• The feature can only detect a cycliststraight from behind and who is moving inthe same direction as your vehicle
• A cyclist who is to the left or right of yourvehicle may be detected late or not at all. •
The camera's capacity to see a cyclist atdawn or dusk is limited, much as it is forthe human eye.
• The camera's function is deactivated andwill not detect a cyclist in darkness or intunnels, even if there is street lighting inthe area.
• For optimal cyclist detection, CitySafety™ must be activated (seepage 172)

* Option/accessory, for more information, see Introduction.193
Introduction
The park assist system is designed to assist you when driving into parking spaces,garages, etc. It utilizes ultrasound sensors inthe front bumper and rear bumper(s) to meas-ure the distance to a vehicle or an object thatmay be close to the front or rear of your vehi-cle. An audible signal and symbols in theaudio system’s display indicate the distanceto the object.
NOTE
A trailer hitch whose wiring is integrated with the vehicle's electrical system will beincluded in the measurement of the availa-ble space behind the vehicle.
WARNING
Park Assist is an information system, NOT a safety system. This system is designedto be a supplementary aid when parkingthe vehicle. It is not, however, intended toreplace the driver's attention and judge-ment.
Function
Park assist button
The system is activated automatically when the vehicle is started. The indicator light in thebutton in the center console illuminates whenthe system is on.
• The front park assist system is active from the time the engine is started untilthe vehicle exceeds a speed of approxi-mately 6 mph (10 km/h). It is also activewhen the vehicle is backing up.
• Rear park assist is active when the engineis running and reverse gear has beenselected.
Activating/deactivatingThe system is activated automatically when the vehicle is started.
–Press the Park assist button on the center console to temporarily deactivate the sys-tem(s).
> The indicator light in the button will go
out when the system has been deacti- vated.
Park assist will be automatically reactivatedthe next time the engine is started, or if thebutton is pressed (the indicator light in thebutton will illuminate).
NOTE
Park assist is disengaged automatically when the parking brake is applied.

NOTE
• Rear park assist is deactivated auto- matically when towing a trailer if Volvogenuine trailer wiring is used. If a non-Volvo trailer hitch is being used, it maybe necessary to switch off the systemmanually, see page 193.
• The system will not detect highobjects, such as a loading dock, etc.
• Objects such as chains, thin shinypoles or low objects may temporarilynot be detected by the system. Thismay result in the pulsing tone unex-pectedly stopping instead of changingto a constant tone as the vehicleapproaches the object. In such cases,use caution when backing up or stopthe vehicle to help avoid damage.
Front park assist
G021424
The distance monitored in front of the vehicle is approximately 2.5 ft (0.8 m). The audiblesignal comes from the audio system's frontspeakers. It may not be possible to combine auxiliary headlights and front park assist since theselights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the parking brake is applied and or when thegear selector is in the
P position.
Faults in the system
If the information symbol illuminates andPark assist syst Service required is shown
on the information display, this indicates that the system is not functioning properly andhas been disengaged. Consult a trained andqualified Volvo service technician.
CAUTION
In certain circumstances, the park assist system may give unexpected warning sig-nals that can be caused by external soundsources that use the same ultrasound fre-quencies as the system. This may includesuch things as the horns of other vehicles,wet tires on asphalt, pneumatic brakes,motorcycle exhaust pipes, etc. This doesnot indicate a fault in the system.

General information
Economical driving conserves natural
resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions. Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.
• Using the engine's optional Eco function 1
can help improve fuel economy. Seepage 134 for additional information. •
Using the transmission's Sport mode 2
may increase fuel consumption some-what. Use the transmission's Drive ( D)
position as often as possible. See page129 for additional information about Sportmode.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extraload) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended.
• Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive more economically.
Other factors that decrease gas mileage are: •
Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and oth-ers are checked at the standard maintenanceintervals.
WARNING
Driving with the tailgate open: Driving
with the tailgate open could lead to poi- sonous exhaust gases entering the pas-senger compartment. If the tailgate mustbe kept open for any reason, proceed asfollows: • Close the windows
• Set the ventilation system control to air flow to floor, windshield and side win-dows and the blower control to itshighest setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.
