Energy distribution in hybrid mode using map data *
The
Hybrid drive mode is the vehicle's
default drive mode in which the electric motor and the combustion engine work sepa-rately or together in hybrid mode. If a destina-tion has been selected in the navigation sys- tem *, the Predictive Efficiency 8
function can
use map data to effectively distribute the electric power consumption throughout thetrip.
This can lower fuel consumption in compari- son with normal hybrid mode, in which thevehicle first runs on electricity and thenswitches to the gasoline engine when thehybrid battery is discharged.
FunctionIf the distance to the selected destination isgreater than the calculated range on the elec-tric motor, the function will distribute the elec-tric power to make consumption as energy-efficient as possible throughout the trip. Thismakes it possible to avoid situations in whichnormal hybrid mode would otherwise use alarge portion of the electric power to e.g. usethe electric motor at high speeds on a high-way and then use the combustion engine atlower speeds during city driving. The greatest fuel savings are achieved when
the trip begins on a highway
the trip is between 50 and 100 km (30and 60 miles) long
the hybrid battery is fully charged at thestart of the trip.
Requirements for the functionCertain conditions must be met for the func-tion to be possible:
A destination must be set in the navigationsystem and the distance to the destinationmust be longer than the possible rangeusing only the electric motor.

Hybrid drive mode must be selected.
The
Hold and Charge functions must be
disabled.
The hybrid battery must be charged.
Usage tipsIf you commute and it is not possible to charge the vehicle at work, enter your work-place as a waypoint and your home as thedestination. Discharging of the hybrid batterywill then be distributed over the entire com-mute to and from work. Add similar commutes, i.e. the route between two charges, as
Favorites in the navigation
system to facilitate access.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. To help achieve the greatest distance with the lowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging it into an electrical outlet. Make it a habit toalways begin trips with the hybrid batteryfully charged.
Locate charging stations along your route.
If possible, choose parking spots withcharging stations.
NOTE
Charge the vehicle from the electricity grid as often as possible!
Preconditioning
Whenever possible, precondition the vehi- cle before driving by connecting thecharging cable to an electrical outlet.
Avoid parking the vehicle somewherewhere the interior will become too hot ortoo cold while the vehicle is parked. If pos- sible, park the vehicle in a climate-con-trolled garage.
During a short drive after passenger com-partment preconditioning, turn off thepassenger compartment fan or the airconditioning in a hot climate.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe hybrid battery.

Driving
Choose the Pure drive mode to help mini-
mize electric power consumption.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. This drive mode has thelowest power consumption.
Balance energy requirements using theaccelerator pedal. Use the indicator on theinstrument panel to see available electricpower and avoid starting the combustionengine unnecessarily. The electric motor ismore effective than the combustionengine, especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will helprecharge the hybrid battery. A regenerativefunction is integrated in the brake pedaland can be augmented by the electricmotor's braking capacity when the gearselector is in mode
B.
Higher speeds increase energy consump-tion - air resistance increases with speed.
Activate the
Hold function in the Function
view at high speeds when traveling farther than is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the
Charge function to charge the hybrid bat-
tery. Charging the battery using the com- bustion engine increases fuel consump- tion and carbon dioxide emissions.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for adviceon suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
Roof loads increase air resistance andincrease fuel consumption. Remove roofboxes, ski racks, etc. that are not in use.
Avoid driving with the windows open.
Do not keep the vehicle still on an upwardgradient by using the accelerator pedal.Use the brakes instead.

Factors affecting electric motor range
A number of factors affect the electric motor's driving range. The ability to achieve along driving range varies according to theoutside conditions and to how the vehicle isdriven.
The certified value for the distance that can be driven using the electric motor should not beconsidered an expected driving range. Theactual range is dependent on a number of fac-tors.
Factors affecting driving rangeThe driver can influence some factors affectingdriving range, but not all. The longest range is achieved under very favorable conditions when all factors positivelyinfluence range.

Hold and Charge functions
In certain situations, it can be useful to con- trol the hybrid battery's charge level while driving. This is possible with the
Hold andCharge functions.Hold and Charge are available in all drive
modes. The functions will switch off if Puredrive mode is activated.
Function buttons for Hold and ChargeThe functions can be activated in the center display's Function view.
Hold
Battery level sustained for later use.
This function retains the charge in the hybrid batteryfor the electric motor andsaves available electrical cur-
rent for use at a later time, such as when driv-ing in an urban area or residential neighbor-hood. The vehicle will function as in normal hybrid driving with a discharged battery - in additionto reusing energy from e.g. regenerative brak-ing, the combustion engine will be used morefrequently to maintain the charge in the bat-tery.
Charge
Engine charges hybrid battery.
This function charges the hybrid battery with the helpof the combustion engine forincreased use of the electric
motor at a later time.
Symbols in the instrument panel
The symbol is displayed in the hybrid battery
gauge when Hold is activated.

STARTING AND DRIVING
44211. Start your vehicle's engine. If the engine
does not start, allow an additional 10 minutes of charging time and then try tostart the engine again.
NOTE
When the engine is started under normal conditions, the vehicle's electrical drivemotor is prioritized – the gasoline engineremains off. This means that after the startknob has been turned clockwise, the elec-tric motor has "started" and the vehicle isready to be driven. Start of the electricmotor is indicated by the indicator lights onthe instrument panel going out and its pre-selected theme illuminating.
CAUTION
Do not touch the connections between the cable and the vehicle during the startattempt. Risk of sparking.
12. Remove the jumper cables in the reverseorder ‒ first the black cables and then the
red cables. Make sure that none of the clamps of the black jumper cables come into contactwith either vehicle's positive (+) jump startterminals or either of the red jumpercable's connected clamps.

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 .
