Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

Battery drain
The electrical functions in the vehicle drain the battery to varying degrees. Avoid usingignition mode II when the engine is switched
off. Use ignition mode I instead, as this uses
less electrical current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical currentwhen the engine is turned off. Examples ofsuch functions are: blower
headlights
windshield wipers
audio system (especially at high volume).
If the starter battery voltage is low, a message is shown in the driver display. The vehicle'senergy-saving function will then turn off orreduce certain functions, such as the blowerand/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (driv-ing charges the battery faster than lettingthe engine idle).

CAUTION
The charging point of the vehicle is only intended for jump starting the vehicle inquestion. The charging point is notintended for jump-starting another vehicle.Using the charging point to start anothervehicle could cause a fuse to blow, whichwould cause the charging point to stopworking.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instrument panel. Volvo recommends contact- ing an authorized Volvo workshop. To avoid short circuits or other damage, the following steps are recommended when jumpstarting the battery:
1. Put the ignition in mode
0.
2. Make sure the auxiliary battery (the bat- tery used to jump start the discharged battery) has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and makesure that the vehicles are not touchingeach other.
4. Clamp the red jumper cable onto the auxil- iary battery's positive (+) terminal (1).
CAUTION
Connect the jump cable carefully to pre- vent short circuits with other componentsin the engine compartment.
5. Fold back the cover over your vehicle'spositive (+) jump start terminal (2).
6. Clamp the other end of the red jumper cable to your vehicle's positive (+) jump start terminal (2).

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Never attempt to tow a Twin Engine vehicle behind another vehicle as this could damagethe electric motor. The vehicle must instead belifted onto a tow truck and transported with allfour wheels on the bed or lifting platform ofthe truck (no wheels may touch the road).
Towing another vehicleTowing another vehicle requires a lot of power - use the Constant AWD drive mode. This
helps charge the hybrid battery and improve the vehicle's driving and roadholding characte-ristics. Before towing another vehicle, check applica- ble speed limit regulations.
Jump startingNever attempt to tow the vehicle to start theengine, as this could damage the electricmotor. Use an auxiliary battery if the start bat-tery's charge level is so low that the enginecannot be started.
CAUTION
Attempts to tow-start the vehicle could cause damage to the electrical drive motorand three-way catalytic converter.

HD Radio™
HD Radio is a brand name registered by the
DTS, Inc. 3
. They are the developer of a broad-
casting technology called IBOC or In Band On Channel, which refers to the method of trans-mitting a digital radio broadcast signal cen-tered on the same frequency as the FM sta-tion's present frequency.
Introduction
Display when the radio is receiving an HD Radio broadcast (generic illustration)
NOTE
HD Radio volume may fade in and out at times due to coverage limitations.
The IBOC system is referred to as a "hybrid" since it is both analog and digital. Duringhybrid operation, receivers still continue toreceive the analog (non-digital) signal. HDRadio receivers incorporate both modes ofreception, where the receiver will automati-cally switch to the analog signal if the digitalsignal cannot be decoded or is lost by thereceiver. When you have tuned to an HD Radio station, the
symbol will appear in the infotain-
ment system display. The symbol will be dis- played in different colors: Grayed-out symbol
: no HD Radio broad-
cast reception
White symbol
: the radio is actively receiv-
ing an HD broadcast
Orange symbol
: the radio is receiving an
HD broadcast with digital sound
More information about HD Radio and IBOC can be found on DTS, Inc.'s website,www.dts.com.
Artist Experience ™A radio station's logo and album art can bedisplayed. If a station opts to provide thisinformation, it is broadcast once every 12minutes, which means that there may be adelay before the logo/album art appear on the screen. The radio can store 100 station logosso the next time the radio is tuned to the samestation, the logo will be displayed immedi-ately. Album art is synched with the artist thatyou are currently listening to.
Ball game modeThis feature means that a main FM station(HD1) will broadcast live events, where thecontent of the programming is more importantthan sound quality, in analog mode only tohelp prevent the delay between analog anddigital broadcasting. The HD Radio symbolwill be white during live broadcasts and "Live"will be displayed next to the symbol.
Benefits of digital broadcasting

Better sound (FM sounds near CD qual-ity).
Some FM frequencies offer a greaternumber of listening choices through multi-casting (consisting of a frequency's mainchannel and any sub-channels that mayalso be available on that particular fre-quency.)
When receiving a digital signal there is nomultipath disturbance or hisses/pops/crackling due to outside influences.

Limitations
Main channel vs. sub-channels (FM only)
: The main channel is the only chan-
nel that can receive in hybrid mode (bothdigital and analog). If a frequency has sub-channels, they are broadcast in digitalmode only. The main FM channel will bedisplayed as, for example, "WRIF-FMHD1". The sub-FM channels will be dis-played as"WRIF-FM HD2", "WRIF-FMHD3", etc.
Reception coverage area
: Due to current
IBOC transmitter power limitations, thereception coverage area in digital mode issomewhat more limited than the station'sanalog coverage area. Be aware that, likeall radio transmission technology, terrain,time of day, vegetation and buildings canhave a positive or negative effect on radioreception.
Analog to digital/digital to analogblending
: Analog to digital blending will
occur as the signal strength reaches a pre-set threshold in the receiver. This will benoticeable in fringe areas (areas with weakreception) and is normal.
NOTE
There may be a noticeable difference in sound quality when a change from ana-logue to digital or digital to analogueoccurs, such as:
Volume increase or decrease
Equalizer settings, i.e., Bass/ Mid-range/Treble cut or boost
Time alignment (Digital program mate-rial in extreme cases can be as muchas 8 seconds behind the analogue).This will noticeable as a "stuttering"effect.
The above items are dependant on thebroadcaster's equipment settings anddo not indicate a fault in the vehicle'sradio receiver or antenna systems .
