WARNING
•City Safety™ only reacts to vehicles traveling in the same direction as yourvehicle and does not react to smallvehicles or motorcycles or to people oranimals.
• City Safety™ is not activated whenyour vehicle is backing up.
• City Safety™ functions at speeds upto 30 mph (50 km/h). This system canhelp prevent a collision if the
differ-
ence in speed between your vehicle
and the vehicle ahead is less than9 mph (15 km/h). If the difference inspeed is greater, a collision cannot beavoided but the speed at which thecollision occurs can be reduced. Thedriver must apply the vehicle’s brakesfor full braking effect.
• City Safety™ will not intervene in apotential collision situation if the vehi-cle is being driven actively. The driveris always responsible for maintaining asafe distance to a vehicle or objectahead.
Function
Location of the laser sensor in the windshield 2
City Safety™ monitors traffic ahead of you using a laser sensor mounted in the uppersection of the windshield. If a collision isimminent, City Safety™ will automaticallyapply the brakes, which may feel like hardbraking. If the difference in speed between your vehi- cle and the vehicle ahead is more thanapproximately 9 mph (15 km/h), City Safety™alone cannot prevent a collision from takingplace. The driver must apply the brakes tohelp avoid a collision or reduce its effect. When the function activates and applies the brakes, a message will appear in the informa- tion display to indicate that the system is/hasbeen active.
NOTE
•
When City Safety™ applies the brakes, the brake lights will illuminate.
• In cases where City Safety™ has stop-ped the vehicle, the system will thenrelease the brakes. The driver mustapply the brakes to keep the vehicle ata standstill.
Using City Safety™
NOTE
The City Safety™ function is activated automatically each time the engine hasbeen switched off and restarted.
On and OffIn certain situations, it may be desirable to switch City Safety™ off, such as when drivingin close quarters where leaves, branches, etc.may obscure the hood and windshield. When the engine is running, City Safety™ can be switched off as follows:

NOTE
The function of aftermarket laser detectors may be affected by City Safety's laser sen-sor.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING
Eye injury may occur if any of the following points are not followed: • It is essential that all pertinent instruc- tions be followed when handling laserinstruments. Testing, repairing, remov-ing, adjusting and/or replacing anycomponents in the laser sensor mayonly be done by a trained and qualifiedVolvo service technician.
• Do not remove the laser sensor(including removal of the lenses). Alaser sensor that has been removedbelongs to laser class 3B according tostandard IEC 60825-1. Devices in laserclass 3B present a risk of injury to theeyes.
• The laser sensor’s connector must bedisconnected before the sensor isremoved from the windshield.
• The laser sensor must be mounted inplace on the windshield before con-necting the sensor’s connector.
• Do not view the laser sensor (whichemits spreading, invisible laser beams)with optical instruments from a dis-tance of less than 4 inches (100 mm).
Symbols and messages in the display
When City Safety™ automatically applies the brakes, one or more of the symbols in themain instrument panel may illuminate and itsassociated message will be displayed. A text message can be erased by pressing briefly on the
OK button on the turn signal

* Option/accessory, for more information, see Introduction.163
WARNING
• Collision Warning will not provide a warning 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 Collision Warningsystem'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, stationaryvehicles and vehicles that are moving in thesame direction as your vehicle. If there is arisk of collision with a vehicle or a pedestrian,the driver is alerted by a flashing red warninglight and an audible warning signal. Collisionwarning is active at speeds above 3 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 or pedestrian, the auto-brake function is activated without the driverpressing the brake pedal. Full brake force isapplied to help reduce the vehicle’s speedwhen the collision occurs or limited brakeforce is applied if this is sufficient to avoid thecollision.
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.
• Collision Warning alerts the driver tothe risk of a collision but this functioncannot reduce the driver’s reactiontime.
• For Collision Warning to be as effec-tive as possible, it is recommendedthat Distance Alert be set to 4 or 5, seepage 153.
NOTE
•When Adaptive Cruise Control is used, the warning light and signal will beused by that function, even if thewarnings provided by Collision Warn-ing have been deactivated by thedriver.
• 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.

Maintenance
Camera and radar sensor

.
In order to function properly, the camera and laser 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 or a vehicle ahead.
• 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 and provides warningsand braking effect most effectively atspeeds up to 30 mph (50 km/h). Forstationary or slow-moving vehicles, thesystem functions best if your vehicle’sspeed is below approximately 45 mph(70 km/h).
• Warnings for stationary or slow-mov-ing vehicles may not be provided indark conditions or in poor visibility.
The Collision Warning system uses the same radar sensors as Adaptive Cruise Control. Formore information on the radar sensor and itslimitations, see page 149.

166* Option/accessory, for more information, see Introduction.
NOTE
If warnings are given too frequently, the warning distance can be reduced (seepage 164). This causes the system to pro-vide later warnings, which decreases thetotal number of warnings provided.
WARNING
• The system is not activated at speeds under approx. 2 mph (4 km/h). There-fore, it will not brake your vehicle if youapproach a vehicle ahead at very lowspeed, such as when parking.
• The driver's actions always have high-est priority and override the CollisionWarning system. This means that thesystem will not intervene in situationswhere the driver is actively steering,braking or pressing the acceleratorpedal, even if a collision is imminent.
• When Auto-brake has prevented a col-lision with a stationary object, yourvehicle will remain at a standstill forapprox. 1.5 seconds. If your vehiclehas been braked for a moving vehicleahead, your vehicle's speed will bereduced to the same speed as thatvehicle's.
The camera’s limitationsThe camera is used by Collision Warning with Auto-brake, Driver Alert Control (seepage 170), and Lane Departure Warning (seepage 173).
NOTE
•To help protect the camera in very hot conditions, it may be temporarilyswitched off for approximately 15minutes after the engine has beenstarted.
• Keep the section of the windshield infront of the camera clean and free ofice, snow, or condensation.
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 pedestrianor another vehicle.

Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only iden- tify and detect a pedestrian who is standingupright. This person can be standing still,walking or running. 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'sentire 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
• Collision Warning with Full Auto-brake and Pedestrian Detection is designedto be a supplementary driving aid. It isnot, however, intended to replace thedriver'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.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the
camera is obscured and cannot detect pedestrians, vehicles or road marker lines infront of the vehicle. This, in turn, means that Collision Warning with Full Auto-brake and Pedestrian Detec-tion, Lane Departure Warning, and DriverAlert Control will not have full functionality. The table lists possible causes for this mes- sage being displayed, and suitable actions.

Park assist*
04
176* Option/accessory, for more information, see Introduction.
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.

178* Option/accessory, for more information, see Introduction.
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 176.
• 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.
• 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 trunk open: Driving with
the trunk open could lead to poisonous exhaust gases entering the passengercompartment. If the trunk must be keptopen for any reason, proceed as follows:
• 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.Remember that these properties can alterwith the vehicle load. The heavier the load inthe trunk, the less the tendency to under-steer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom-mended pressure according to the vehicleload. See the "Tire pressure" section. Loadsshould be distributed so that capacity weight
