Windshield washing
Washing function Move the lever toward the steering wheel to start the windshield and headlight washers.After the lever is released the wipers makeseveral extra sweeps.
Heated washer nozzles*The washer nozzles are heated automaticallyin cold weather to help prevent the washerfluid from freezing.
High-pressure headlight washing*High-pressure headlight washing consumes alarge quantity of washer fluid. To save fluid,the headlights are washed using two alterna-tives:
• Low/high beam headlights on.
The
headlights will be washed the first time the windshield is washed. Thereafter, theheadlights will only be washed once forevery five times the windshield is washedwithin a 10-minute period.
• Parking lights on.
Optional Active Bend-
ing Lights will be washed once for everyfive times the windshield is washed. Nor-mal halogen headlights will not bewashed.
CAUTION
• Use ample washer fluid when washing the windshield. The windshield shouldbe thoroughly wet when the wipers arein operation.
• When approx. 1 US quart (1 liter) ofwasher fluid remains in the reservoir,the headlights will no longer bewashed. A text message will also bedisplayed to remind the driver to fill thewasher fluid reservoir.

}}
* Option/accessory, for more information, see Introduction.141
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 331 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.

03 Your driving environment
Brakes
03
142
The adaptive brake lights activate if: •The ABS system activates for more than approximately a half second
• In the event of sudden braking while thevehicle is moving at speeds aboveapproximately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake lights and additional taillights remain onfor as long as the brake pedal is depressed oruntil braking force on the vehicle is reduced.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the engine is run-ning. Never let the vehicle roll to a stop withthe engine switched off. If the power brakes are not working, consid- erably higher pressure will be required on thebrake pedal to compensate for the lack ofpower assistance. This can happen for exam-ple when towing your vehicle or if the engineis switched off when the vehicle is rolling. Thebrake pedal feels harder than usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing throughan automatic car wash can cause water tocollect on the brake discs and pads. This willcause a delay in braking effect when the pedal is depressed. To avoid such a delaywhen the brakes are needed, depress thepedal occasionally when driving through rain,slush, etc. This will remove the water from thebrakes. Check that brake application feelsnormal. This should also be done after wash-ing or starting in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strainwhen driving in mountains or hilly areas, orwhen towing a trailer. Vehicle speed is usuallyslower, which means that the cooling of thebrakes is less efficient than when driving onlevel roads. To reduce the strain on thebrakes, shift into a lower gear and let theengine help with the braking. Do not forgetthat if you are towing a trailer, the brakes willbe subjected to a greater than normal load.
Anti-lock braking system (ABS)The Anti-lock Braking System (ABS) helps toimprove vehicle control (stopping and steer-ing) during severe braking conditions by limit-ing brake lockup. When the system "senses"impending lockup, braking pressure is auto-matically modulated in order to help preventlockup that could lead to a skid. The system performs a brief self-diagnostic test when the engine has been started anddriver releases the brake pedal. Another auto-matic test may be performed when the vehi-
cle first reaches a speed of approximately6 mph (10 km/h). The brake pedal will pulsateseveral times and a sound may be audiblefrom the ABS control module, which is nor-mal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. Thisdelay is minimized by cleaning the brake lin-ings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and afterthe vehicle has been washed. Do this bybraking gently for a short period while thevehicle is moving.
Emergency Brake AssistanceEBA is designed to provide full brake effectimmediately in the event of sudden, hardbraking. The system is activated by the speedwith which the brake pedal is depressed. When the EBA system is activated, the brake pedal will go down and pressure in the brakesystem immediately increases to the maxi-mum level. Maintain full pressure on thebrake pedal in order to utilize the systemcompletely. EBA is automatically deactivatedwhen the brake pedal is released.

Hill Descent Control (HDC)*
03
}}
* Option/accessory, for more information, see Introduction.147
Introduction
Normally, when the accelerator pedal is released while driving down hills, the vehicle'sspeed slows as the engine runs at lower rpm(the normal engine braking effect). However, ifthe downhill gradient becomes steeper and ifthe vehicle is carrying a load, speed increasesdespite the engine braking effect. In this sit-uation, the brakes must be applied to reducethe vehicle's speed. HDC is a type of automatic engine brake and makes it possible to increase or decrease thevehicle's speed on downhill gradients usingonly the accelerator pedal, without applyingthe brakes. The brake system functions auto-matically to maintain a low and steady speed. 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. Thedriver has full responsibility for driving in asafe manner.
Function
• HDC can be switched on and off with the button in the center console. An indicatorlight in the button illuminates when HDCis activated.
• The indicator light
in the instru-
ment panel illuminates and a message is displayed when the system is controllingthe vehicle's speed.
• HDC only functions when
first or reverse
gears are selected (
1 will be shown in the
instrument panel display when first gear is selected).
NOTE
HDC cannot be activated if the gear selec- tor is the D position.
Using HDC
HDC allows the car to roll forward at a maxi- mum speed of 6 mph (10 km/h), and 4 mph(7 km/h) in reverse. However, the acceleratorpedal can be used to select any speed that ispossible in first or reverse gears. When theaccelerator pedal is released, speed isquickly reduced again to 6 mph (10 km/h) or4 mph (7 km/h), depending on the gearselected, regardless of the hill's gradient. It isnot necessary to apply the brakes.
• The brake lights illuminate automatically when HDC is controlling the vehicle'sspeed.
• The driver can slow or stop the vehicle atany time by applying the brakes.
HDC is deactivated when:
• The button on the center console ispressed
• A gear higher than first gear is selected
• D
is selected on vehicles with an auto-
matic transmission
HDC can be deactivated at any time. If this is done while driving down a steep hill, the sys-tem's braking effect will decrease gradually.

}}
* Option/accessory, for more information, see Introduction.165
•
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 152)
• 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 169) and Collision Warning with FullAuto-brake and Pedestrian Detection (seepage 178). 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.

}}
173
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:

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 152) 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 173.
• 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.

* Option/accessory, for more information, see Introduction.195
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.
