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.

•
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.

Active chassis (Four C)
Active chassis, Four-C (Continuously Con- trolled Chassis Concept), regulates the cha-racteristics of the shock absorbers so that thevehicle's driving characteristics can beadjusted. There are three settings: Comfort,Sport and Advanced.
NOTE
This system is available on Canadian mod- els only.
ComfortComfort mode offers a somewhat softer ride and the transmission shifts gears at lowerrpm. This mode is particularly suitable forlong-distance highway driving. The indicatorlight in the button will be on when this modeis selected.
SportIn this mode, the vehicle's body sway isreduced during cornering and steeringresponse is more immediate. The transmis-sion shifts up at higher rpm for sportier driv-ing. The indicator light in the button will be onto indicate that Sport mode has beenselected.
AdvancedIn this mode, body sway in curves is minimaland steering response is very direct. Gearshifting is done at high rpm in each gear fordynamic and active driving.
Operation

Sub-channels
Example of an HD Radio station with sub-chan- nels
In many cases, a main HD Radio station (FM wavebands only) will also have sub-channelsoffering additional types of programming ormusic. In such cases, the “-” symbol will be dis- played to the left of the frequency numberand a number will be displayed to the right ofthe frequency number indicating that the cur-rently tuned frequency has at least one sub-channel.
Selecting sub-channelsTo listen to a station's sub-channel(s), press and hold the right arrow key on the centerconsole or on the steering wheel keypad forapproximately 1 second. To go back to the main channel, press and hold the left arrowkey on the center console or on the steeringwheel keypad for approximately 1 second. Togo to subchannel 2 (if available), press andhold the right arrow key on the center consoleor on the steering wheel keypad for approxi-mately 1 second. If you are currently tuned to a frequency's main channel, pressing and holding the leftarrow key for approximately 1 second willtune to the next lower radio frequency.
NOTE
•
When the radio has gone into HD mode, it may take several secondsbefore the ">" symbol (if the currentfrequency has any sub-channels) isdisplayed to the left of the frequency.Pressing and holding the arrow keysfor approximately 1 second before themain-/sub-channel icon is displayedwill cause the radio to tune to the nextavailable radio station, not to the cur-rent station's sub-channels.
• When you are no longer in broadcast-ing range of the currently tuned
sub-
channel ,
No reception will be dis-
played. The radio will then be muted and it will be necessary to tune to orsearch for a new radio station.
Sub-channels can also be stored as presets, see page 251 for information on storing sta-tions. If you press a sub-channel's preset button, it may take up to 6 seconds before the channel
becomes audible. If you press this buttonwhile you are out of digital range of the trans- mitter,
No reception will be displayed.
SiriusXM™ satellite radio*
Listening to satellite radioThe SiriusXM ™ satellite system consists of a
number of high elevation satellites in geosyn- chronous orbit.
NOTE
• The digital signals from the satellites are line-of-sight, which means thatphysical obstructions such as bridges,tunnels, etc, may temporarily interferewith signal reception.
• Avoid any obstructions, such as metal-lic objects transported on roof racks orin a ski box, or other antennas thatmay impede signals from the Sir-iusXM
™ satellites.

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.

08 Wheels and tires
General information

Introduction
Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to roadhazard damage and, depending on drivingconditions, may achieve a tread life of lessthan 20,000 miles (30,000 km). Even if thisvehicle is equipped with Volvo’s advancedAWD or DSTC system, these tires are notdesigned for winter driving, and should bereplaced with winter tires when weatherconditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of road holding on slippery surfacesthan tires without the "all-season" rating.However, for optimum road holding on icy orsnow-covered roads, we recommend suitablewinter tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the car's roadholding andhandling characteristics.
New Tires
Remember that tires are perishable goods. Asof 2000, the manufacturing week and year(Department of Transportation (DOT) stamp)will be indicated with 4 digits (e.g., 1513means that the tire illustrated was manufac-tured during week 15 of 2013).
Tire rotationYour vehicle has no required tire rotation. Tire wear is affected by a number of factors suchas tire inflation, ambient temperature, drivingstyle, etc.
NOTE
•
If the tires are rotated, they should only be moved from front to rear orvice versa. They should never be rota-ted left to right/right to left.
• Ideally, tire rotation should be done thefirst time after approximately 3,000miles (5,000 km) and thereafter at6,000-mile (10,000-km) intervals.Some customers find that tire rotationmay help to get extra mileage from tirelife.
• Tire rotation should only be performedif front/rear tire wear is fairly even andtread height is above 1/16" (1.6 mm).
Tire ageTires degrade over time, even when they are not being used. It is recommended that tiresgenerally be replaced after 6 years of normalservice. Heat caused by hot climates, fre- quent high loading conditions or Ultra Violet(U.V.) exposure can accelerate the aging
