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.

152
Introduction
The Dynamic Stability and Traction Control system (DSTC) consists of a number of func-tions designed to help reduce wheel spin,counteract skidding, and to generally helpimprove directional stability.
CAUTION
A pulsating sound will be audible when the system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel spin by transferring power from a drivewheel that begins to lose traction to thewheel on the opposite side of the vehicle (onthe same axle). TC is most active at low speeds.This is one of DSTC's permanent functions and cannot be switched off.
Active Yaw Control (AYC)This function helps maintain directional stabil-ity, for example when cornering, by brakingone or more of the wheels if the vehicleshows a tendency to skid or slide laterally.This is one of DSTC's permanent functionsand cannot be switched off.
Spin control (SC)The spin control function is designed to helpprevent the drive wheels from spinning whilethe vehicle is accelerating.
Trailer Stability Assist – TSA
1Trailer Stability Assist helps stabilize a vehiclethat is towing a trailer when the vehicle andtrailer have begun to sway. See page 304 formore information. This system is automatically deactivated if the driver selects
Sport mode.
Operation
Sport modeThe stability system is always activated and cannot be switched off. However, the driver can select Sport mode,
which offers more active driving characteris- tics. In this mode, the engine managementsystem monitors movement of the acceleratorpedal and steering wheel for sportier driving by allowing more lateral movement of the rearwheels before DSTC is activated. Under certain circumstances, such as when driving with snow chains, or driving in deepsnow or loose sand, it may be advisable totemporarily use
Sport mode for maximum
tractive force. If the driver releases pressure on the acceler- ator pedal, DSTC will also activate to helpstabilize the vehicle. To switch to Sport mode:
1. Press the My Car button in the center
console control panel and select
My
XC70
DSTC in the menu.
2. Unselect the symbol and leave the menu by pressing EXIT.
> This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is switched off. DSTC will return to normalmode when the engine is restarted.

}}
* 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.

Signals from the park assist system
View in the display (warning for objects front left/ right rear)
Visual indicatorThe audio system’s display gives an overview of the vehicle’s position in relation to adetected object. The marked sectors in the display indicate that one or more of the sensors has detectedan object. The closer the car symbol comesto a sector, the closer the vehicle is to theobject. If the infotainment system is switched off, the park assist system will not be able to providea visual indicator. An audible signal will stillbe provided.
Audible signalThe Park Assist system uses an intermittenttone that pulses faster as you come close toan object, and becomes constant when youare within approximately 1 ft (30 cm) of anobject in front of or behind the vehicle. Ifthere are objects within this distance bothbehind and in front of the vehicle, the tonealternates between front and rear speakers.
NOTE
The level of the audible signal can be low- ered/raised with the infotainment volumecontrol. The level can also be set in the MYCAR menu system. See page 209 for adescription of the menu system.
If the volume of another source from the audio system is high, this will be automati-cally lowered.
Rear park assist
G017833
The distance monitored behind the vehicle is approximately 5 ft (1.5 m). The audible signalcomes from the rear speakers. The system must be deactivated when towing a trailer, carrying bicycles in a rear-mountedcarrier, etc, which could trigger the rear parkassist system's sensors.

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.

Rear Park Assist Camera (PAC)*
04
}}
* Option/accessory, for more information, see Introduction.197
Introduction
The Park Assist Camera (PAC) uses the dis- play in the center console to show the areabehind the car while you are backing up. PAC also shows guiding lines in the on- screen image to indicate the direction that thevehicle will take as it moves rearward, whichhelps simplify parallel parking, backing into atight space or when attaching a trailer to thevehicle. The images of vehicles in this section are generic and may not depict your specificmodel.
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
• PAC is designed to be a supplemen- tary aid when parking the vehicle. It isnot, however, intended to replace thedriver’s attention and judgment.
• The camera has blind spots where itcannot detect objects or peoplebehind the vehicle.
• Pay particular attention to people oranimals that are close to the vehicle.
• Objects seen on the screen may becloser than they appear to be.
Function
The driver sees what is behind the vehicle and if a person or animal should suddenlyappear from the side. PAC is mounted on the tailgate, near the opening handle. The camera has built-in electronics that help reduce the “fish-eye” effect so that the imageshown on the screen is as natural as possi-ble. This may cause some objects on thescreen to “lean,” which is normal.
Ambient lighting conditionsThe camera automatically monitors the ambi-ent lighting conditions behind the vehicle andconstantly adjusts sensitivity to light. Thismay cause the brightness and quality of theimage on the screen to vary slightly. Sensitiv-ity to light is increased in dark conditions or inbad weather, which may affect image quality. If the image on the screen seems too dark, brightness can be increased with the thumbwheel on the lighting panel.
NOTE
In order to function properly, the camera lens should always be kept clean. This isparticularly important in bad weather.Keep the lens free of dirt, ice or snow.
