Parking on a hill
Always use the parking brake when parking on a hill.
WARNING
Always apply the parking brake when parking on an incline. Selecting a gear or putting the automatic transmission in P may not be suffi-
cient to keep the vehicle stationary in all sit- uations.
If the vehicle is pointing uphill: • Turn the front wheels so they are pointing away from
the curb.
If the vehicle is pointing downhill:
• Turn the front wheels so they are pointingtoward
the curb.
Heavy load uphill
Heavy loads, such as a trailer, could cause the vehicle to roll backward when the parking brakeis released automatically on steep uphill gradi-ents. To help avoid this, pull the control upwardwhile you are driving away. Release the controlwhen the vehicle gains traction.

Parking brake malfunction
If you are unable to deactivate or activate the parking brake after several attempts, contact anauthorized Volvo workshop.
A audible warning signal will sound if the parking brake is applied while the vehicle is being driven. If the vehicle must be parked before the problem is rectified, turn the wheels as when parking on an incline and put the gear selector in P.
Low battery charge levelIf the battery charge level is too low, it will not be possible to apply or release the parking brake.Connect an auxiliary battery to the vehicle if thebattery is discharged.
Replacing brake padsDue to the design of the electric parking brake,the rear brake pads must be replaced by a work-shop. An authorized Volvo workshop is recom-mended.

All Wheel Drive (AWD)
*
All-wheel drive, All Wheel Drive (AWD), also called four-wheel drive, means that power is dis-tributed to all four wheels, which improves trac-tion.
To achieve the best traction, power is automati- cally directed to the wheels that have the bestgrip. The system continuously calculates theneed for torque to the rear wheels, and canimmediately redistribute up to half of the engine'storque to the rear wheels. All-wheel drive also has a stabilizing effect at higher speeds. In normal driving conditions, mostof the engine's power is directed to the frontwheels. When the vehicle is stationary, all-wheeldrive is always activated in preparation for maxi-mum traction during acceleration. All-wheel drive reacts differently depending on which drive mode * is selected.

ECO
• Adapt the vehicle for more fuel-efficient and eco-friendly driving with Eco mode.
In this mode, the Start/Stop function is activatedand certain climate settings are reduced. The instrument panel has an ECO gauge to facili- tate fuel-efficient driving.
DYNAMIC
• Dynamic mode is designed to provide sport- ier driving characteristics and a faster accel-eration response.
Gear shifting will be faster and more distinct andthe transmission will prioritize gears with a highertraction force. Steering response is faster and suspension is stiffer 4
to help reduce body roll when cornering.
The Start/Stop function is deactivated.
INDIVIDUAL
• Customizes drive mode to personal preferen- ces.
Select one of the drive modes as a basis andadjust the settings to achieve your preferred driv- ing characteristics. These settings will be stored in your driver profile. Individual drive mode is only available if it has been activated in the center display.Settings view 5

Audio, media and Internet
The audio and media system consists of a media player and a radio. A cellular phone can also beconnected through Bluetooth to use hands-freefunctions or play music in the vehicle. When thevehicle is connected to the Internet, it is alsopossible to use apps to play media.
Audio and media overview
The functions can be controlled using voice com- mands, the steering wheel keypad or the centerdisplay. The number of speakers and amplifiersvaries depending on the audio system installed inthe vehicle.
System updates
The audio and media system is continuously improved. When the vehicle has an Internet con-nection, system updates can be downloaded foroptimal functionality; see support.volvocars.com.

Sound settings
The audio system is precalibrated for optimal sound reproduction but these settings can bepersonalized.
The system's volume is normally adjusted using the volume control below the center display orthe right-side steering wheel keypad. Thisapplies, for example, when playing music or theradio or during phone calls and active traffic mes-sages.
Optimal sound reproductionThe audio system is precalibrated for optimalsound reproduction using digital signal process-ing. This calibration takes into account speakers,amplifiers, passenger compartment acoustics, lis-tener position, etc. for each combination of vehi-cle model and audio system. There is also adynamic calibration that takes into account thevolume control setting and the vehicle's speed.
Sound settings as needed
In Top view under SettingsSound, the fol-
lowing settings can be selected:
•
Tone — personal preference for bass, treble,
equalizer for example.
•
Balance - balance between right/left and
front/rear speakers.
•
System Volumes – adjusts volume in the
various systems of the car, e.g. Voice
Control, Park Assist and Phone Ringtone.

WHEELS AND TIRES
518
Tires
The function of the tires is to carry loads, provide traction on road surfaces, reduce vibrations andprotect the wheels from wear.
The tires significantly influence the vehicle's driv- ing characteristics. The type, dimensions, tirepressure and speed rating have a considerableimpact on how the vehicle performs. Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pil-lar (the structural member at the side of the vehi-cle, at the rear of the driver's door opening).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheel com-bination designed to provide maximum drypavement performance with consideration forhydroplaning resistance. They may be moresusceptible to road hazard damage and,depending on driving conditions, may achievea tread life of less than 30,000 km (20,000miles). Even if this vehicle is equipped withVolvo's advanced AWD or stability system,these tires are not designed for winter driving,and should be replaced with winter tires whenweather conditions dictate.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces.It should be noted however that the tires havebeen developed to give these features on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higher degree of road-holding on slippery road surfaces than tires with-out the "all-season" rating. However, for optimalroadholding on icy or snow-covered roads, werecommend snow tires on all four wheels. When replacing tires, be sure that the new tires are the same size designation, type (radial) andpreferably from the same manufacturer, on all four wheels. Otherwise there is a risk of alteringthe vehicle's roadholding and handling characte-ristics.
Recommended tiresOn delivery, the car is equipped with Volvo origi- nal tires that have the VOL
1
marking on the side
of the tires. These tires have been designed spe- cifically for your vehicle. It is therefore importantwhen replacing tires that the new tires have thissame marking to help maintain the vehicle's driv-ing characteristics, comfort and fuel consumption.
New tires
Tires are perishable goods. After a few years, they will begin to harden and their friction proper-ties will gradually deteriorate. Always replace tireswith the freshest tires possible. This is particularlyimportant for snow tires. A series of numbers is

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.
