WARNING
Please be aware that there is no sound from the 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 Twin Engine 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.
Hybrid-unique functions
Drive modes
Different drive modes can be selected while driv- ing, e.g., electric power only or a combination ofelectric and gasoline power. The vehicle calcu-lates the optimal combination of drivability, drivingexperience, environmental impact and fuel econ-omy for the selected drive mode. See also thearticle "Drive modes" for additional information.
Instrument panel
In certain driving situations, hybrid-unique infor- mation may be displayed in the instrument panel,such as: a hybrid battery gauge (current chargelevel), the current drive mode, a symbol that illu-minates when the gasoline engine is being used,a Hybrid Guide and the level of energy regenera-tion.
Preconditioning
In order to function optimally, the hybrid battery (and its related electrical systems) and the gaso-line engine (and its drive systems) should be atthe correct operating temperature. The hybridbattery's capacity is reduced considerably if it istoo cold or hot. Preconditioning prepares thevehicle's drive systems and passenger compart-ment before the vehicle is driven to help reducewear and energy consumption.
Charging the hybrid battery
CAUTION
Never connect the charging cable if there is a risk of thunderstorms/lightning.
Twin Engine Plug-in Hybrid vehicles use a lith- ium-ion battery that can be charged in severalways:
• A charging cable can be connected from thevehicle to a 110-volt AC socket. Chargingtime depends on the strength of the current.
• When the brakes are applied lightly, the elec-tric motor is used for engine braking, duringwhich the vehicle's kinetic energy is conver-ted into electric current that is used to helprecharge the hybrid battery.
• The hybrid battery is also recharged to a cer-tain extent when the gasoline engine is inoperation.

Volvo and the environment Volvo is committed to the well-being of its cus- tomers. As a natural part of this commitment, wecare about the environment in which we all live.Concern for the environment means an everydayinvolvement in reducing our environmentalimpact.
Volvo's environmental activities are based on a holistic view, which means we consider the over-all environmental impact of a product throughoutits complete life cycle. In this context, design, pro-duction, product use, and recycling are all impor-tant considerations. In production, Volvo haspartly or completely phased out several chemicalsincluding CFCs, lead chromates, asbestos, andcadmium; and reduced the number of chemicalsused in our plants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic converter with aLambda sond, now called the heated oxygen sen-sor, in 1976. The current version of this highlyefficient system reduces emissions of harmfulsubstances (CO, HC, NOx) from the exhaust pipeby approximately 95 – 99% and the search toeliminate the remaining emissions continues.Volvo is the only automobile manufacturer tooffer CFC-free retrofit kits for the air conditioningsystem of all models as far back as the 1975model 240. Advanced electronic engine controlsand cleaner fuels are bringing us closer to ourgoal. In addition to continuous environmentalrefinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in the work to lessen the car's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
• Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• Drive at a constant speed whenever possible.
• See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
• Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
• When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.
Twin Engine Plug-in Hybrid vehicles
• If possible, precondition the vehicle with thecharging cable before driving.
• If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
• Choose the
Pure drive mode to help mini-
mize electric power consumption.
• In hilly terrain, put the gear selector in mode B
to utilize the electric motor's braking func-
tion when the accelerator pedal is released. This helps charge the hybrid battery.

Trip computer The trip computer registers and calculates infor- mation such as distance driven, fuel consump-tion and average speed. This information is dis-played in the instrument panel.
To help promote fuel efficient driving, the trip computer provides readings for current and aver-age fuel consumption. The trip computer includes the following gauges:
• Trip odometers
• Odometer
• Current fuel consumption
• Distance to empty
• Tourist (alternative speedometer)
Trip odometerThere are two trip odometers: TM and TA. During a drive, the trip odometer registers:
• Mileage
• Driving time
• Average speed
• Average fuel consumption
The values displayed are those since the lasttime the trip odometer was reset.
OdometerThe odometer registers the vehicle's total mile-age and cannot be reset.
Current fuel consumptionThis gauge shows the current fuel consumption.This reading is updated once a second.
Distance to emptyThis function shows the approximate distancethat can be driven on the fuel remaining in thetank. The calculation is based on average fuel con- sumption during the last 20 miles (30 km) ofdriving and the amount of fuel remaining in thetank. When the gauge displays "----", there is very little useable fuel remaining in the tank; refuel as soonas possible.

INSTRUMENTS AND CONTROLS
100The accuracy of this figure may vary if your driv- ing style changes. An economical driving style willgenerally increase this distance.
Distance to discharged batteryThis gauge shows the approximate dis-tance that can be driven on the chargeremaining in the hybrid battery.
When the gauge displays "----" there is no guar- anteed driving charge remaining in the battery. This calculation is based on the average electrical current consumption in a normally loaded vehicleduring normal driving, and whether the A/C is on or off. Changing drive modes from
Hybrid toPure may increase the calculated distance to a
discharged battery since Pure mode reduces
certain climate system functions. An economical driving style will generally increase this distance.
Distance using the electric motor
To get the optimal driving distance using the electric motor, it is essential to conserve current.Functions that use a great deal of current (e.g.,audio system, electrical heating in the steeringwheel/door mirrors/rear window/seats, very coldair from the climate system, etc.) reduce the pos-sible driving distance.
NOTE
In addition to high electrical consumption in the passenger compartment, fast accelera-tion, sudden braking, heavy loads, low ambienttemperatures and driving up hills can reducethe possible driving distance.
Tourist (alternative speedometer)This is an alternative digital speedometer can be used when driving in areas in which the speedlimit is listed in a different unit of measure. If the speedometer is in mph, this gauge will show the
vehicle's speed in km/h and vice versa.

Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
• Before leaving on a trip, fill the fuel tank andmake sure the hybrid battery is fully charged.During the trip, make a habit of refueling reg-ularly.
• Check for fuel, oil, and fluid leakage.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drive in countries where it may be difficult toobtain the correct fuel.
• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Driving economically with Twin EnginePlug-in Hybrid vehicles
Plan your driving in order to utilize the electric motor as much as possible. An energy-conserving driving style lowers current consumption from the hybrid battery and helpsincrease electric driving range.
Charging
• Charge the hybrid battery as often as possi- ble from the electricity grid using the charg-ing cable. Whenever possible, begin a drivewith a fully charged battery.
• Check the location of charging points.
• Where possible, choose parking spaces withcharging points.

STARTING AND DRIVING

Preconditioning
•If possible, precondition the vehicle with the charging cable before driving.
• Avoid parking the vehicle so that the passen-ger compartment becomes too hot or cold.Park, if possible, in a climate controlled park-ing garage.
• For short drives after using the precondition-ing function, turn off the climate systemblower if possible.
• If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reduces thehybrid battery's charge level.
Driving
•
Choose the Pure drive mode to help mini-
mize electric power consumption.
• Maintain a constant speed and an adequate distance to the vehicle ahead to minimizeuse of the brakes.
• Balance energy requirements using theaccelerator pedal and utilize the gauge onthe instrument panel to see the amount ofpower available from the electric motor. Thishelps avoid starting the gasoline engineunnecessarily. The electric motor is moreenergy-efficient than the gasoline engine,especially at lower speeds. See also the arti-cle "Hybrid-related symbols and messages". •
Brake as gently as possible; doing socharges the hybrid battery. There is a regen-erative function in the brake pedal which canbe augmented by the electric motor's brakingcapacity when the gear selector is in mode B
.
• Higher speeds increase energy consumption and the vehicle's wind resistance increasesalong with speed. Do not exceed postedspeed limits.
• In hilly terrain, put the gear selector in mode B
to utilize the electric motor's braking func-
tion when the accelerator pedal is released. This helps charge the hybrid battery.
• Use the
Hold function at highway speeds
when traveling farther than is possible using the hybrid battery's capacity.
• Whenever possible, avoid using the
Chargefunction to charge the hybrid battery. Charg- ing the battery using the gasoline engineincreases fuel consumption and carbon diox-ide emissions.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold).
• Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended. •
Note that roof racks, ski racks, etc, increaseair resistance and also energy consumption.
• Avoid driving with open windows.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so thatcapacity weight or maximum permissible axleloads are not exceeded.
• At the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stabilityand reduces the risk of rear wheel skid.Remember that these properties can alterwith the vehicle load. The heavier the load inthe cargo compartment, the less the ten-dency to understeer.
