Hybrid battery - The hybrid battery's functionis to store electrical current. This energy isprovided by plugging the charging cable intoan electrical outlet, through regenerativebraking or from the high-voltage generator.This provides current to power the electricmotor and to temporarily power the electricalair conditioning to precondition the passen-ger compartment.
Combustion engine - The combustion enginestarts when the charge level in the hybridbattery is too low to provide the power outputrequested by the driver.
High-voltage generator2 - Charges the hybridbattery. Starter for the combustion engine.
Can provide the combustion engine withextra electrical current.
Electric motor - Powers the vehicle usingelectricity. Can provide extra torque andpower during acceleration. Provides electricalall-wheel drive functionality. Regeneratesbraking energy into electrical current.

Starting and stopping thecombustion engine in Twin Enginevehicles
An advanced control system determines the dis-tance that the vehicle can be driven on the com-bustion engine, electric motor, or both at thesame time. When driving on only the electricmotor, the vehicle may automatically start thecombustion engine due to outside circumstan-ces, e.g. low ambient temperatures. This is com-pletely normal. The combustion engine will alsoalways start when the hybrid battery is nearlyfully discharged.

Climate settings at low temperatures
At low ambient temperatures, the combustionengine will sometimes start automatically to helpachieve the desired passenger compartmenttemperature and air quality. The amount of timethe combustion engine is running can be affec-ted by:
lowering the temperature
reducing blower speed
activating Pure drive mode.

Using the electric motor in hot or cold
weather
At very low or high ambient temperatures, theelectric motor's driving range and power may be

Economical driving
Drive economically and more environmentallyconscious by thinking ahead, avoiding rapidstarts and stops and adapting driving style andspeed to the current traffic conditions.
To help achieve the greatest distance with thelowest fuel consumption with Twin Engine,observe the following:
Charge
Charge the vehicle regularly by plugging itinto an electrical outlet. Make it a habit toalways begin trips with the hybrid battery fullycharged.
Locate charging stations along your route.
If possible, choose parking spots with charg-ing stations.

NOTE
Charge the vehicle from the electricity grid asoften as possible!

Preconditioning
Whenever possible, precondition the vehiclebefore driving by connecting the chargingcable to an electrical outlet.
Avoid parking the vehicle somewhere wherethe interior will become too hot or too coldwhile the vehicle is parked. If possible, parkthe vehicle in a climate-controlled garage.
During a short drive after passenger com-partment preconditioning, turn off the pas-senger compartment fan or the air condition-ing in a hot climate.
If preconditioning is not possible when it iscold outside, use seat and steering wheelheating first. Avoid heating the entire pas-senger compartment to reduce the amountof current being taken from the hybrid bat-tery.

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.

Factors the driver cannot control
There are several outside conditions that affectrange to varying degrees:
the current traffic situation
driving short distances
topography
ambient temperature and headwinds
road conditions and road surface.
The following table shows the approximate rela-tionship between ambient temperature and driv-ing range with normal climate settings and withclimate settings turned off.
Up to a certain limit, warmer ambient tempera-tures increase the electric motor's driving range.
Ambient tem-peratureClimate set-tings turnedoff
Normal cli-mate set-tings

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.

Driving through standing water
Driving the vehicle through a deep pool of stand-ing water on a water-covered roadway is calledfording. This must be done with great caution.
To prevent damage to the vehicle when drivingthrough water (e.g. on flooded roads):
Do not drive in water higher than the floor ofthe vehicle. If possible, check the depth ofthe water at its deepest point before drivingthrough it. Be particularly careful when driv-ing through flowing water.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to help avoidthe risk of corrosion.

4.Avoid overfilling the tank. Do not press thehandle on the filler nozzle again after it hasinitially stopped pumping.
>The fuel tank is now filled.

NOTE
An over-full tank may overflow in hot weather.

CAUTION
Avoid spilling gasoline during refueling. Inaddition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.

Refueling from a fuel container
When filling from a fuel container, use the funnelprovided in a foam block under the floor hatch inthe cargo compartment.
1. Open the fuel filler door.
2. Insert the funnel into the fuel filler pipe'sopening. There are two flaps just inside thefuel filler pipe and the tube section of thefunnel must push both of these flaps openbefore fuel can be added.

Fuel
Volvo recommends the use of detergent gaso-line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.

NOTE
Volvo recommends not using external fuelinjector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.

Unleaded fuel
All Volvo vehicles have a three-way catalytic con-verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of
