Drive-E ‒ purer driving pleasure
Volvo is committed to the well-being of its customers. As a natural part of this commit-ment, we care about the environment inwhich we all live. Concern for the environ-ment means an everyday involvement inreducing our environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider theoverall environmental impact of a productthroughout its complete life cycle. In this con-text, design, production, product use, andrecycling are all important considerations. Inproduction, Volvo has partly or completelyphased out several chemicals including CFCs,lead chromates, asbestos, and cadmium; andreduced the number of chemicals used in ourplants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic converterwith a Lambda sond, now called the heatedoxygen sensor, in 1976. The current version ofthis highly efficient system reduces emissionsof harmful substances (CO, HC, NOx) from theexhaust pipe by approximately 95 - 99% andthe search to eliminate the remaining emis-sions continues. Volvo is the only automobilemanufacturer to offer CFC-free retrofit kits forthe air conditioning system of all models as farback as the 1975 model 240. Advanced elec-tronic engine controls and cleaner fuels arebringing us closer to our goal. In addition to continuous environmental refinement of con-ventional gasoline-powered internal combus-tion engines, Volvo is actively looking atadvanced technology alternative-fuel vehicles. When you drive a Volvo, you become our part- ner in the work to lessen the vehicle's impacton the environment. To reduce your vehicle'senvironmental impact, you can:
Maintain proper air pressure in your tires.Tests have shown decreased fuel econ-omy with improperly inflated tires.
Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
Drive at a constant speed whenever possi-ble.
See a trained and qualified Volvo servicetechnician as soon as possible for inspec-tion if the check engine (malfunction indi-cator) light illuminates, or stays on afterthe vehicle has started.
Properly dispose of any vehicle-relatedwaste such as used motor oil, used batter-ies, brake pads, etc.
When cleaning your vehicle, please usegenuine Volvo car care products. All Volvocar care products are formulated to beenvironmentally friendly.
Twin Engine vehicles
If possible, precondition the vehicle withthe charging cable before driving.
If preconditioning is not possible in coldweather, use the seat and steering wheelheating primarily. Avoid heating the entirepassenger compartment, which reducesthe hybrid 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 function when the acceleratorpedal is released. This helps charge thehybrid battery.

Hybrid gauge In Hybrid and Pure drive modes, the instru- ment panel will display a hybrid gauge, whichcan help the driver achieve optimal drivingeconomy.
The hybrid gauge shows the ratio between the electric motor's current power consumptionand the remaining available power. This infor-mation is shown in various ways.
Symbols in the hybrid gaugeIndicates the current available powerfrom the electric motor. A solid sym-bol indicates that the electric motoris being used.
A hollow symbol indicates that the electric motor is not being used.
Indicates the power level when the internal combustion engine starts. Asolid symbol indicates that the inter-nal combustion engine is being used.
Indicates the power level when the internal combustion engine will start.A hollow symbol indicates that theinternal combustion engine is not
being used.
Indicates that the hybrid battery is being charged, e.g. by lightly press-ing the brake pedal.
Driver-requested powerThe hybrid gauge displays the amount of power requested (utilized) by the driverthrough pressure on the accelerator pedal. Thehigher the reading on the scale, the morepower utilized in the current gear. The markbetween the lightning symbol and the dropsymbol indicates the point at which the com-bustion engine will start.

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.

Preparing for a long trip
It is important to have the vehicle's systems and equipment checked carefully before driv-ing long distances.
Check that
the engine is running properly and that fuel consumption is normal
there are no leaks (fuel, oil or other fluid)
the brake pedal is functioning properly
all lights are working
‒ adjust the head-
light height if the vehicle is carrying aheavy load
tire tread depth and air pressure are atcorrect levels. Change to snow tires whendriving in areas where there is a risk ofsnowy or icy roads
the start battery is sufficiently charged
the wiper blades are in good condition

Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to makesure it can be driven safely.
Before the cold season arrives: Make sure the engine coolant contains 50% antifreeze. This mixture helps pro-tect the engine from frost erosion down toapprox. –35 °C (–31 °F). Do not mix dif-ferent types of antifreeze as this couldpose a health risk.
Keep the fuel tank well filled to preventcondensation from forming.
Check the viscosity of the engine oil. Oilwith low viscosity (thinner oil) improvescold-weather starting and reduces fuelconsumption when driving with a coldengine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
Check the condition and charge level of the start battery. Cold weather placesgreater demands on the start battery andreduces its capacity.
Use washer fluid containing antifreeze tohelp prevent ice from forming in thewasher fluid reservoir.
Slippery driving conditionsTo help optimize traction and roadholding,Volvo recommends using snow tires on allwheels whenever there is a risk of snow or iceon the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under controlled conditions to learn how the vehiclereacts.

Opening/closing the fuel filler door
A button on the instrument panel is used to unlock the fuel filler door.
An arrow next to the fuel pump symbol in the instru-ment panel indicates the sideof the vehicle on which thefuel filler door is located.
1. Press the button on the dashboard.
> Pressure equalization in the fuel tankcauses a slight delay before the fuel filler door opens. The message
Preparing for refuel Fuel lid will be
unlocked when ready will appear in
the instrument panel. When the system is ready, the message
Fuel tank Ready
for refueling will be shown. If the gas-
oline engine is activated when the but- ton is pressed, it will usually be deacti-vated and the vehicle will switch toelectric propulsion.
NOTE
Refueling must be done within approxi- mately 15 minutes of opening the fuel fillerdoor. After this time, the valve opened bypushing the button for opening the fuelfiller door will close and it will no longer bepossible to refuel without the pump's noz-zle switching off. If the valve is closed before refueling is complete - press the button again and waituntil the driver display shows the message
Fuel tank Ready for refueling.
2. After refueling, press the fuel filler door lightly to close it.

WHEELS AND TIRES
520
TiresThe function of the tires is to carry loads, pro- vide traction on road surfaces, reduce vibra-tions and protect the wheels from wear.
The tires significantly influence the vehicle's driving characteristics. The type, dimensions,tire pressure and speed rating have a consid-erable impact on how the vehicle performs. Your vehicle is equipped with tires according to the vehicle's tire information placard on theB-pillar (the structural member at the side ofthe vehicle, at the rear of the driver's dooropening).
WARNING
A damaged tire could cause the driver to lose control of the vehicle.
CAUTION
Some Volvo models are equipped with an Ultra High Performance tire and wheelcombination designed to provide maxi-mum dry pavement performance with con-sideration for hydroplaning resistance.They may be more susceptible to road haz-ard damage and, depending on drivingconditions, may achieve a tread life of lessthan 30,000 km (20,000 miles). Even ifthis vehicle is equipped with Volvo'sadvanced AWD or stability system, thesetires are not designed for winter driving,and should be replaced with winter tireswhen weather conditions dictate.
The tires have good road holding characteris- tics and offer good handling on dry and wetsurfaces. It should be noted however that thetires have been developed to give these fea-tures on snow/ice-free surfaces. Most models are equipped with "all-season" tires, which provide a somewhat higherdegree of roadholding on slippery road surfa-ces than tires without the "all-season" rating.However, for optimal roadholding on icy orsnow-covered roads, Volvo recommendssnow tires on all four wheels. When replacing tires, be sure that the newtires are the same size designation, type(radial) and preferably from the same manu-facturer, on all four wheels. Otherwise there isa risk of altering the vehicle's roadholding andhandling characteristics.
Recommended tiresOn delivery, the car is equipped with Volvo original tires that have the VOL
1
marking on
the side of the tires. These tires have been designed specifically for your vehicle. It istherefore important when replacing tires thatthe new tires have this same marking to helpmaintain the vehicle's driving characteristics,comfort and fuel consumption.

WHEELS AND TIRES

Checking tire pressure
Correct inflation pressure helps improve driv- ing stability, save fuel and increase the serv-ice life of the tires.
Tire pressure decreases over time, which is normal. Tire pressure also varies depending onthe ambient temperature. Driving on under-inflated tires could cause the vehicle to over-heat and lead to damage. Tire pressure affectstraveling comfort, road noise and driving cha-racteristics. Check the pressure in the tires every month. Use the recommended inflation pressure forcold tires to help maintain good tire perform-ance. Under-inflated or over-inflated tirescould cause uneven tread wear. Use an air pressure gauge and check the infla- tion pressure on all the tires, including the spare tire 4
, at least once a month and before
long trips. Volvo recommends buying a relia- ble air pressure gauge, as the automaticgauges provided at service stations may beinaccurate.
WARNING
Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation,or "blow-out," with unexpected loss ofvehicle control and increased risk ofinjury.
Under-inflated tires reduce the loadcarrying capacity of your vehicle.
Cold tiresInflation pressure should be checked when thetires are cold. The tires are considered to becold when they have the same temperature asthe surrounding (ambient) air. This tempera-ture is normally reached after the vehicle hasbeen parked for at least 3 hours. After driving for approximately 1.6 km (1 mile), the tires are considered to be warm. If youneed to drive longer than that to inflate thetires, check and record the inflation pressureof the tires first and inflate accordingly whenyou arrive at the pump. When the ambient temperature changes, so does the inflation pressure. A 10-degree tem-perature drop causes a corresponding drop ininflation pressure of 1 psi (7 kPa). Check theinflation pressure of the tires regularly andadjust to the correct pressure, which can be found on the vehicle's tire information decal orcertification label. If you check inflation pressure when the tires are warm, you should never release air. Thetires become warm after driving and it is nor-mal for warm tires to have an inflation pres-sure above the recommended pressure forcold tires. A warm tire with an inflation pres-sure equal to or under the recommended pres-sure for cold tires could be significantly under-inflated.Related information
