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.

Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles *.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function.
WARNING
If the vehicle does not have electrical current and both the electric motor and gasolineengine are switched off, the brakes cannot beused to stop the vehicle.
When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle is carrying a heavy load, using brake mode B to
augment the brakes or the
Off Road* drive mode can also be used on steep downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System
ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Function check when the engine is
started
A Plug-in Hybrid is equipped with a "brake bywire" brake system. A function check is per-formed each time the engine is started and thedriver depresses the brake pedal to move the gear selector from P.
In certain cases, a message may appear in the instrument panel saying that pressure on thebrake pedal is too low. Press harder on the pedal.
Light braking charges the hybrid batteryWhen the brakes are applied lightly, the electricmotor's braking function is used, which converts

Brake functions
The vehicle's standard braking features are aug- mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking brake, the vehicle is equipped with several auto-matic brake assist functions. These systems helpthe driver by e.g., keeping the vehicle stationarywhen the brake pedal is not depressed (at a traf-fic light or intersection), when starting up a hill orwhen driving down a hill. These systems include: • Auto-hold brakes
• Hill Start Assist
• Braking assist after a collision
• Hill Descent Control

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.
