General information about TwinEngine
Twin Engine vehicles are driven just like anyother vehicle, but certain functions differ from avehicle powered exclusively by gasoline. Theelectric motor powers the vehicle primarily at lowspeeds; the gasoline engine is used at higherspeeds or during more active driving.
The instrument panel displays Twin Engine-spe-cific information - charging information, selecteddrive mode, distance to discharged battery andhybrid battery charge level.
Different drive modes can be selected while driv-ing, e.g. electric power only or, if more power isneeded, a combination of electric and gasolinepower. The vehicle calculates the optimal combi-nation of driveability, driving experience, environ-mental impact and fuel economy for the selecteddrive mode.
In order to function optimally, the hybrid battery(and its electrical drive systems) and the gasolineengine (and its drive systems) must be at thecorrect operating temperature. Battery capacitycan be considerably reduced if the battery is toocold or too hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before driving to help reduce both wear andenergy consumption. It also helps increase thehybrid battery's range.
The hybrid battery which powers the electricmotor is recharged using the charging cable. It
can also be recharged during light braking andthrough engine braking in gear position B. Thecombustion engine can also help recharge thehybrid battery.
Important
No electrical current
Keep in mind that if there is no electrical currentto the vehicle, i.e. the ignition is switched off orthe start battery is discharged, certain functionssuch as brakes, power steering, etc. will not work.
WARNING
If the vehicle does not have electrical currentand both the electric motor and the gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
Towing not permitted
Never tow a Twin Engine vehicle behind anothervehicle, as this could damage the electric motor.
Exterior engine noise
WARNING
Please be aware that there is no sound fromthe engine when the vehicle is being poweredby the electric motor and it may be difficult todetect by children, pedestrians, cyclists andanimals. This is especially true at low speeds.
High-voltage electrical current
WARNING
A number of electrical components in TwinEngine Plug-in Hybrid vehicles use high-volt-age current and can be extremely dangerousif handled incorrectly. These components andany orange wiring in the vehicle may only behandled by trained and qualified Volvo servicetechnicians.
Do not touch anything that is not clearly descri-bed in this Owner's Manual.

Hybrid
This is the default mode in which the electricmotor and combustion engine work together.
The vehicle starts in Hybrid mode. The controlsystem uses both the electric motor and the gas-oline engine - separately or in tandem - and cal-culates optimal utilization with regard to perform-ance, fuel consumption and comfort. Drivingcapacity on the electric motor alone is deter-mined by factors such as the hybrid battery'scharge level, the need for heat or cooling in thepassenger compartment, etc.
If there is sufficient charge in the battery, it ispossible to drive solely on electric power. Whenthe accelerator pedal is pressed, only the electricmotor will be activated until the battery reaches acertain charge level. Above this level, the currentin the battery cannot supply the power requestedby the accelerator pedal and the combustionengine will start.
When the hybrid battery's charge level is low, thecombustion engine will start more frequently tosave the remaining current in the battery. Chargethe hybrid battery from a 120-240 volt outletusing a charging cable, or activate Charge inFunction view to reset the option of only usingthe electric motor.
This drive mode is designed for low energy con-sumption with an optimized mix between theelectric motor and gasoline engine, without com-promising on climate comfort or driving experi-
ence. When faster acceleration is requested bythe driver, the electric driveline will be utilized tohelp provide maximum additional power.
The vehicle also monitors the driving conditionsand automatically engages all-wheel drive if nec-essary. All-wheel drive and extra electric powerare always available regardless of the battery'scharging status.
Information in the instrument panel
When driving in Hybrid mode, a hybrid gauge willbe displayed in the instrument panel. The gaugewill indicate the amount of electrical currentrequired when the driver depresses the accelera-tor pedal. The marker between the lightning andthe drop shows how much current is available.
The instrument panel gauge when both the electricmotor and the combustion engine are being used.
The instrument panel also shows howmuch current is being restored to thebattery (regenerated) during light brak-ing.
Pure
Uses the electric motor only, with the lowestpossible energy consumption and carbondioxide emissions.
This drive mode maximizes the use of the hybridbattery. Certain climate system functions arereduced to provide the longest distance usingonly electricity.
Pure mode is available when the hybrid battery issufficiently charged. Even in Pure mode, thecombustion engine will start if the charge level inthe battery gets too low. The combustion enginewill also start
if the vehicle's speed goes above 125 km/h(78 mph)
if the driver requests more power than theelectric motor can provide
if factors such as cold weather affect thesystem or components.
STARTING AND DRIVING

* Option/accessory.421
Driving
Choose the Pure drive mode to help mini-mize electric power consumption.
Maintain a steady speed and a generous fol-lowing distance to traffic ahead to minimizebraking. This drive mode has the lowestpower 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 combustion engine,especially at low speeds.
When braking is necessary, brake gentlyusing the brake pedal. This will help rechargethe hybrid battery. A regenerative function isintegrated in the brake pedal and can beaugmented by the electric motor's brakingcapacity when the gear selector is in modeB.
Higher speeds increase energy consumption- air resistance increases with speed.
Activate the Hold function in the Functionview at high speeds when traveling fartherthan is possible using the hybrid battery'scapacity.
Whenever possible, avoid using the Chargefunction to charge the hybrid battery. Charg-ing the battery using the combustion engine
increases fuel consumption and carbon diox-ide emissions.
In a cold climate, reduce heating of the wind-shield/rear window, mirrors, seats and thesteering wheel.
Maintain the correct pressure in the tires andcheck pressure regularly.
The type of tires used could affect energyconsumption - consult a retailer for advice onsuitable tires.
Remove unnecessary items from the vehicle- the heavier the load, the higher the fuelconsumption.
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. Usethe brakes instead.

Factors affecting electric motorrange
A number of factors affect the electric motor'sdriving range. The ability to achieve a long driv-ing range varies according to the outside condi-tions and to how the vehicle is driven.
The certified value for the distance that can bedriven using the electric motor should not beconsidered an expected driving range. The actualrange is dependent on a number of factors.
Factors affecting driving range
The driver can influence some factors affectingdriving range, but not all.
The longest range is achieved under very favora-ble conditions when all factors positively influ-ence range.

Preparing for a long trip
It is important to have the vehicle's systems andequipment checked carefully before driving longdistances.
Check that
the engine is running properly and that fuelconsumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning optimally
all lights are working ‒ adjust the headlightheight if the vehicle is carrying a heavy load
tire tread depth and air pressure are at cor-rect levels. Change to snow tires when driv-ing in areas where there is a risk of snowy oricy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before drivingin cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
Make sure the engine coolant contains 50%antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
Keep the fuel tank well filled to prevent con-densation from forming.
Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.
CAUTION
Low-viscosity oil should not be used with harddriving or in hot weather.
Check the condition and charge level of thestart battery. Cold weather places greaterdemands on the start battery and reduces itscapacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.
Slippery driving conditions
For optimal traction and roadholding, Volvo rec-ommends using snow tires on all wheels when-ever there is a risk of snow or ice on the road.
NOTE
Certain countries require use of winter tiresby law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con-trolled conditions to learn how the vehicle reacts.

STARTING AND DRIVING
434
If contact occurs, flush the affected areaimmediately with water. Obtain medicalhelp immediately if eyes are affected.
Never expose the battery to open flameor electric spark. Do not smoke near thebattery. Failure to follow the instructionsfor jump starting can lead to injury.
NOTE
The vehicle cannot be started if the hybridbattery is discharged.
NOTE
If the starter battery has been discharged tothe extent that the vehicle does not have nor-mal electrical functions and the engine mustthen be jump-started with an external batteryor a battery charger, the Start/Stop functionmay remain activated. If the Start/Stop func-tion shortly thereafter auto-stops the engine,there is a huge risk that auto-start of theengine will fail due to insufficient batterycapacity since the battery had not had time torecharge.
If the vehicle has been jump-started or ifthere has not been enough time for the bat-tery to be charged with a battery charger, theStart/Stop function should be temporarilydeactivated until the battery has beenrecharged by the vehicle. At an ambient tem-perature of about +15°C (about 60°F), thebattery must be charged by the vehicle for atleast one hour. At lower ambient tempera-tures, the charging time can increase to3-4 hours. It is advisable to charge the batterywith an external battery charger.

Driving with a trailer
There are a number of things to consider whentowing a trailer, such as the towbar, the trailerand how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi-cle's curb weight. The total weight of all passen-gers and any installed accessories, e.g. towbar,reduces the vehicle's load-carrying capacity bythe corresponding amount.
Towbars used on the vehicle must beapproved for the applicable use.
Distribute the load on the trailer so that theweight on the towbar complies with thespecified maximum towball weight. Thetongue weight is calculated as part of thevehicle's payload.
Increase the tire pressure to the recom-mended pressure for a full load.
The engine is subjected to more load thanusual when towing a trailer.
Towing a trailer affects the vehicle's han-dling, durability and driving economy.
Do not drive with a heavy trailer when thevehicle is very new. Wait until the mileagehas reached at least 1000 km (620 miles).
On long and steep downgrades, the vehicle'sbrakes are subjected to much more loadthan usual. When manually shifting, down-shift and adapt speed accordingly.

MAINTENANCE AND SERVICE
576
NOTE
If the starter battery becomes discharged toomany times, it will shorten its service life.
The service life of the starter battery is affec-ted by several factors, such as driving condi-tions and climate. The starting capacity of thebattery reduces gradually over time. The bat-tery must therefore be recharged if the vehi-cle is not used or a long period of time or if itis only driven short distances. Severe cold fur-ther limits the starting capacity.
To keep the starter battery in a good condi-tion, the vehicle should be driven at least15 minutes per week or the battery should beconnected to a battery charger with automatictrickle charging.
A starter battery that is always kept fullycharged has the maximum service life.
Location
The start battery is located in the trunk.
WARNING
If the starter battery is disconnected, the func-tion for automatic opening and closing mustbe reset to function correctly. A reset isrequired in order for the pinch protection towork.
CAUTION
On certain models, the battery is secured witha tensioning strap. Make sure that the ten-sioning strap is always securely tightened.
