Brake system
The brake system is a hydraulic system con- sisting of two separate brake circuits. If aproblem should occur in one of these circuits,it is still possible to stop the vehicle with theother brake circuit. If the brake pedal must be depressed farther than normal and requires greater foot pres-sure, the stopping distance will be longer. A warning light in the instrument panel will light up to warn the driver that a fault hasoccurred. If this light comes on while driving or braking, stop immediately and check the brake fluidlevel in the reservoir.
NOTE
Press the brake pedal hard and maintain pressure on the pedal – do not pump thebrakes.
WARNING
If the fluid level is below the MIN mark in
the reservoir or if a brake system message is shown in the information display: DO
NOT DRIVE . Have the vehicle towed to a
trained and qualified Volvo service techni-cian and have the brake system inspected.
Brake pad inspectionOn vehicles equipped with a jack*, the condi- tion of the brake pads can be checked byraising the vehicle (see page 312 for informa-tion about using the jack and removing awheel) and performing a visual inspection ofthe brake pads.
WARNING
• If the vehicle has been driven immedi- ately prior to a brake pad inspection,the wheel hub, brake components,etc., will be very hot. Allow time forthese components to cool before car-rying out the inspection.
• Apply the parking brake and put thegear selector in the Park (
P) position.
• Block the wheels standing on theground, use rigid wooden blocks orlarge stones.
WARNING
•Use the jack intended for the vehicle when changing a tire. For any otherjob, use stands to support the vehicle.
• The jack should be kept well-greasedand clean, and should not be dam-aged.
• Be sure the jack is on a firm, level,non-slippery surface.
• No objects should be placed betweenthe base of jack and the ground, orbetween the jack and the attachmentbar on the vehicle.
• The jack must correctly engage thejack attachment.
• Never allow any part of your body tobe extended under a vehicle suppor-ted by a jack.
Brake lightsThe brake lights come on automatically when the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event of sudden braking or if the ABS system isactivated. This function causes an additionaltaillight on each side of the vehicle to illumi-nate to help alert vehicles traveling behind.

Adaptive Cruise Control (ACC)*
04
* Option/accessory, for more information, see Introduction.151
•
The gear selected is moved to
P,N or R
• The driver presses the
button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the park- ing brake in order to continue keeping thevehicle at a standstill. This happens if:
• The driver opens the door or takes off his/her seat belt
• DSTC is put in Sport mode (seepage 138)
• ACC has kept the vehicle at a standstillfor more than 2 minutes
• The engine has been switched off
• The brakes have overheated
The radar sensor and its limitations
In addition to being used by ACC, the radar sensor is also used by Distance Alert (seepage 155) and Collision Warning with FullAuto-brake and Pedestrian Detection (seepage 164). This sensor is designed to detectcars or larger vehicles driving in the samedirection as your vehicle, in the same lane.
WARNING
• If there is visible damage to the front grille or you suspect that the radarsensor may be damaged in any way,contact a trained and qualified Volvoservice technician as soon as possible.The radar sensor may only functionpartially (or not at all) if it is damagedor is not securely fastened in place.
• Accessories or other objects, such asextra headlights, must not be installedin front of the grille.
• Modification of the radar sensor couldmake its use illegal.
The radar sensor's capacity to detect vehi- cles ahead is impeded:
• if the radar sensor is obstructed and can- not detect other vehicles, for example inheavy rain, or if snow or other objects areobscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor clean.
• if the speed of vehicles ahead is signifi- cantly different from your own speed.
Situations where ACC may not function optimally
WARNING
•The radar sensor has a limited field of vision. In some situations it may detecta vehicle later than expected or notdetect other vehicles at all.
• If ACC is not functioning properly,cruise control will also be disabled.

City Safety™
04
159
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:

Select
Off.
If the engine is switched off, City Safety™ will reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni- tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
• Follow the same procedure as for switch- ing City Safety™ off but select
On.
Limitations
The sensor used by City Safety™ is designed to detect cars and other larger motor vehiclesahead of your vehicle in both daylight anddarkness.
WARNING
The laser sensor has certain limitations and its function may be reduced (or it maynot function at all) in conditions such asheavy rain or snowfall, or by dense fog orthick, blowing dust or snow. Condensa-tion, dirt, ice or snow on the windshieldmay also interfere with the sensor’s func-tion.
Objects such as warning flags hanging from long objects on the roof or accessories suchas auxiliary lights or protective arches on thefront of the vehicle that are higher than thehood may also impede the sensor’s function. Braking distance to the vehicle ahead increa- ses on slippery road surfaces, which mayreduce City Safety’s capacity to avoid a colli-sion. In situations like this, the DSTC system(see page 138) will help provide the best pos-sible braking capacity and stability. City Safety™ emits a laser beam and meas- ures the way in which the light is reflected.Therefore, vehicles or objects with low-reflec-tive surfaces may not be detected. Normally,the license plate and taillight reflectors givethe rear section of a vehicle ahead sufficientreflective surfaces to be detected.
NOTE
•Keep the windshield in front of the laser sensor free of ice, snow, dirt, etc.See page 159.
• Snow or ice on the hood deeper than2 inches (5 cm) may obstruct the sen-sor. Keep the hood free of ice andsnow.
• Do not mount or in any way attachanything on the windshield that couldobstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the City Safety™ laser sensor is obstructed insome way and cannot detect vehicles aheadof you, which means that the system is notfunctioning. However, this message will not be displayed in all situations in which the sensor isobstructed. For this reason, the driver mustensure that the area of the windshield in frontof the sensor is always kept clean. The following table shows some of the situa- tions that can cause the message to be dis-played and suggested actions.

180* 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 178.
• 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
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.

Blind Spot Information System (BLIS)*
04
186* Option/accessory, for more information, see Introduction.
Introduction
BLIS is an information system that indicates the presence of another vehicle moving in thesame direction as your vehicle on roads withseveral lanes. The system helps provide infor-mation about:
• Other vehicles in your door mirrors' "blind area"
• Vehicles that are about to pass your vehi-cle in the left and/or right lanes
• Cross Traffic Alert (CTA) is a supple- mentary BLIS function
intended to
detect vehicles crossing behind your vehicle while you are backing up.WARNING
• BLIS and CTA are information sys- tems, NOT warning or safety systemsand do not function in all situations.
• BLIS and CTA do not eliminate theneed for you to visually confirm theconditions around you, and the needfor you to turn your head and should-ers to make sure that you can safelychange lanes or back up.
• As the driver, you have full responsibil-ity for changing lanes/backing up in asafe manner.

The number or combinations of options on the vehicle may not leave a space availableon the center console for the BLIS button. Ifthis is the case, BLIS can be deactivated/reactivated in the MY CAR menu system (see
page 197)
• Select Off or On in
SettingsCar
settings
BLIS.
When BLIS is deactivated/reactivated, the indicator lights will go out/illuminate (the indi-cators will also flash once when the functionis reactivated) and a message will appear inthe instrument panel. To erase the message: •
Press the
OK button on the left steering
wheel lever
or
• Wait for approx. 5 seconds for the mes- sage to disappear
When does BLIS function
Zone 1. Blind area, Zone 2. Area for passing vehicles
The system functions when your vehicle is moving at speeds above 6 mph (10 km/h). BLIS is designed to react to:
• Other vehicles in your door mirrors' "blind area"
• Vehicles that are passing your vehicle When BLIS detects a vehicle in zone 1 or a passing vehicle in zone 2, the indicator light inthe door panel will glow steadily. If the driverthen uses the turn signal on the side on whichthe warning is given, the indicator light willflash and become brighter.
WARNING
•
BLIS does not function in sharp curves.
• BLIS does not function when yourvehicle is backing up.
Deactivating/reactivating CTA
On vehicles equipped with the optional Park assist system (see page 178), Cross TrafficAlert (CTA) can be deactivated/reactivated bypressing the Park assist button on the centerconsole.

When does CTA function
How CTA works
CTA supplements BLIS by warning the driver of crossing traffic behind your vehicle, forexample, when backing out of a parkingspace. It is primarily designed to detect another vehi- cle but in certain cases may also detectpedestrians or smaller objects such as bicy-cles. CTA is only activated when the vehicle is backing up and is activated automaticallywhen the gear selector is put in reverse.
• An audible signal indicates that CTA has detected something that is approachingfrom the side. The signal will come fromeither the left or right audio systemspeakers, depending on which the side of your vehicle the approaching vehicle/object has been detected.
• CTA also provides a warning by illuminat-ing the BLIS indicator lights.
• An icon will also illuminate in the Parkassist graphic on the center console dis-play.
LimitationsCTA has limitations in certain situations, for example, the CTA sensors cannot "see"through other parked vehicles or obstruc-tions. The following are several examples where CTA's "field of vision" may initially be limitedand approaching vehicles cannot be detecteduntil they are too close:
