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.

Economical driving
Drive economically and more environmentally conscious by thinking ahead and avoidingrapid starts and stops.
Adapt your driving style and speed to the cur- rent traffic conditions. Observe the following rules:
For lower fuel consumption, activate
Ecodrive mode.
Use the Eco Coast function in drive mode
Eco - engine braking is deactivated, allow-
ing the vehicle's kinetic energy to be used to roll greater distances.
Use gear
D as often as possible and avoid
using the kick-down function.
For manual gear shifting, use the highestpossible gear for the current traffic situa-tion and road conditions - fuel consump-tion is reduced at lower engine speeds (rpm). Use the gear indicator 13
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking.
Fuel consumption is increased at highspeeds - air resistance increases withspeed.
The trip computer's current fuel consump-tion indicator can help promote more fuel-efficient driving.
Do not warm up the engine by idling. It isbetter to begin driving normally immedi-ately after starting the engine. A coldengine uses more fuel than a warmengine.
Whenever possible, avoid using the vehi-cle to drive short distances. The enginedoes not have time to reach a normaloperating temperature and this leads toincreased fuel consumption.
Use engine braking to brake the vehicle,when this is safe for other road users.
Maintain the correct pressure in the tiresand check pressure regularly.
The type of tires used could affect fuelconsumption - 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.

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.

WHEELS AND TIRES
500
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.

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

Tire pressure monitoring system

The tire pressure monitoring system 6
pro-
vides a warning symbol in the instrument panel if pressure is too low in one or moretires.
This symbol illuminates to indicate low inflation pressure. If there is a system malfunction, the inflation pressure warning symbol
will flash for approximately one minute andthen glow steadily.
System descriptionThe tire pressure monitoring system measures differences in rotational speed between thewheels through the ABS system to determineif the tires are properly inflated. If inflationpressure in a tire is too low, its diameter (andconsequently its rotational speed) changes. Bycomparing the tires with each other, the sys-tem can determine if the pressure in one ormore tires is too low.
General information about the tire pressure monitoring system
In the following description, the tire monitor- ing system is generally referred to as TPMS. Each tire, including the spare (if provided) 7
should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different size thanthe size indicated on the vehicle placard or tireinflation pressure label, you should determinethe proper tire inflation pressure for thosetires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (TPMS) that illuminates a low tirepressure telltale when one or more of yourtires is significantly under-inflated. Accord-ingly, when the low tire pressure telltale illumi-nates, you should stop and check your tires assoon as possible, and inflate them to theproper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tirefailure. Under-inflation also reduces fuel effi-ciency and tire tread life, and may affect thevehicle's handling and stopping ability. Pleasenote that the TPMS is not a substitute forproper tire maintenance, and it is the driver'sresponsibility to maintain correct tire pressure,even if under-inflation has not reached thelevel to trigger illumination of the TPMS lowtire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when

CAUTION
Risk of overheating. The compressor should not be running for longer than 10minutes at a time.
5. Inflate the tire to the pressure specified on
the tire pressure decal on the driver's side door pillar. If the inflation pressure is toohigh, use the air release valve to releaseair.
6. Switch off the compressor. Remove the hose and the electrical cable.
7. Screw the valve cap back onto the tire.
NOTE
After inflating a tire, always replace the valve cap to help prevent valve damagecaused by gravel, dirt, etc.
Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
NOTE
The compressor is an electric device. Fol- low local regulations for disposal.

Determining the vehicle's permitted weight
Properly loading your vehicle will provide maximum return of vehicle design perform-ance.
Weight designationsBefore loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or without atrailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weight
The weight of the vehicle including a full tank of fuel and all standard equipment. It does notinclude passengers, cargo, or optional equip-ment.
Capacity weight
All weight added to the curb weight, including cargo and optional equipment. When towing,towbar weight is also part of cargo weight.
Permissible axle weight
The maximum allowable weight that can be carried by a single axle (front or rear). Thesenumbers are shown on the Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label. The total load on each axlemust never exceed its maximum permissibleweight.

Engine oil For the recommended service intervals and warranties to be applied, an approved engineoil must be used.
Volvo recommends:
If the engine oil is not checked regularly and the level becomes low, this could cause seri-ous engine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filled with a specially adapted syntheticengine oil. Great care has been put into thechoice of oil, with consideration given toservice life, startability, fuel consumptionand environmental impact. For the recommended service intervals to apply, an approved engine oil must beused. Only use the prescribed oil grade totop off or change the oil. Otherwise, thereis a risk of the vehicle's service life, starta-bility, fuel consumption and environmentalimpact being affected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Cor-poration disclaims warranty liability forsuch type of damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low.On engine variants with an oil pressure sensor,

Wash using a sponge, car washing deter- gent and plenty of lukewarm water.
Clean the wiper blades with lukewarmsoap solution or car washing detergent.
Dry the vehicle using a clean, soft chamoisor a squeegee. Try not to let drops ofwater dry in strong sunlight. This couldcause water drying stains that may needto be polished out.
In areas with heavy industrial emissions,more frequent washing of the vehicle'sexterior is recommended.
Tar spots from asphalt may remain evenafter washing. Use a tar remover toremove these spots.
WARNING
Always entrust engine washing to a work- shop. If the engine is hot, there is a risk offire.
CAUTION
Dirty headlights do not work as well. Clean them regularly, e.g. when refueling. Do not use corrosive cleaners. Use water and a non-abrasive sponge.
NOTE
Exterior lighting such as headlights and taillights may develop temporary conden-sation on the inside of the lens. This is nor-mal. All exterior lighting is designed toresist this. Condensation is normally ven-ted out of the lamp housing once the lighthas been lit for some period of time.
CAUTION
Make sure that the panoramic roof and sun shade are closed before washingthe vehicle.
Never use abrasive polishing agents onthe panoramic roof.
Never use wax on the rubber sealsaround the panoramic roof.
