Economical driving
A more economical driving style can help lower fuel consumption.
Before driving
If possible, precondition the vehicle before driving.
If preconditioning is not possible when itis cold outside, use seat and steeringwheel heating first. Avoid heating theentire passenger compartment to reducethe amount of current being taken fromthe start battery.
Avoid using idling to warm up the vehiclebefore driving.
The type of tires and inflation pressureused could affect energy consumption –consult an authorized Volvo retailer foradvice on suitable tires.
Remove unnecessary items from the vehi-cle - the heavier the load, the higher thefuel consumption.
While driving

Activate Eco drive mode.
Use gear selector position
D as often as
possible.
When using manual gear shifting, drive using the highest possible gear. Use the gear indicator 19
.
Maintain a steady speed and a generous following distance to traffic ahead to mini-mize braking. Use engine braking if possi-ble.
Higher speeds increase energy consump-tion because air resistance increases withspeed.
In a cold climate, reduce heating of thewindshield/rear window, mirrors, seatsand the steering wheel.
Avoid driving with the windows open.
Do not use the accelerator pedal to keepthe vehicle stationary on an uphill gradi-ent. Instead, activate the auto-hold brakefunction at a standstill.
Use trip data to see current fuel consump-tion.
WARNING
Never turn off the engine while the vehicle is moving, e.g. when driving downhill. Thisdeactivates certain important systemssuch as power steering and brakes.

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
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.
Check the condition and charge level ofthe 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.
See separate section for engine oil recommen-dations.

Driving through standing water
It may be necessary to drive the vehicle through standing water e.g. deep puddles orflooding on the road. This must be done withgreat caution.
The vehicle can be driven through water up to a depth of 30 cm (11 in) at no more than walk-ing speed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When youhave passed the water, press lightly on thebrake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc.can make the brake linings slippery, resultingin delayed braking effect. If the vehicle is equipped with contacts for an electric heater or trailer coupling, cleanthese after driving in water or mud.
Do not allow the vehicle to stand in waterup to the sills any longer than absolutelynecessary. This could result in electricalmalfunctions.
CAUTION
Engine damage could occur if water enters the air cleaner.
If water enters the transmission, thelubricating ability of the oils is reducedand the service life of these systems isshortened.
Damage to any component, engine,transmission, turbocharger, differentialor its internal components caused byflooding, vapor lock or insufficient oil isnot covered under warranty.
If the engine stalls while the vehicle isin water, do not attempt to restart it.Have the vehicle towed out of thewater to a workshop. An authorizedVolvo workshop is recommended. Riskof engine failure.
CAUTION
Because it can be difficult to determine the water depth, Volvo recommends not driv-ing through standing or running water. Thedriver is always responsible for operatingthe vehicle in a safe manner and adheringto all applicable laws and regulations.

Fuel
Volvo recommends the use of detergent gas- oline to control engine deposits.
Deposit control gasoline (gasoline with detergent additives)
Detergent gasoline is effective in keeping injectors and intake valves clean. Consistentuse of deposit control gasolines will helpensure good driveability and fuel economy. Ifyou are not sure whether the gasoline containsdeposit control additives, check with the serv-ice station operator.
NOTE
Volvo recommends not using external fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before orafter refueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic converter and must only use unleaded gaso-line. US and Canadian regulations require thatpumps delivering unleaded gasoline arelabeled "UNLEADED". Only the nozzles ofthese pumps will fit in your vehicle's fuel fillerinlet. It is unlawful to dispense leaded fuel intoa vehicle labeled "unleaded gasoline only".Leaded gasoline damages the three-way cata-lytic converter and the heated oxygen sensor system. Repeated use of leaded gasoline willlessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicleinspection programs will make detection ofmisfueling easier, possibly resulting in emis-sion test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tricar-bonyl (MMT). If such fuels are used, yourEmission Control System performancemay be affected, and the Check EngineLight (malfunction indicator light) locatedon your instrument panel may light. If thisoccurs, please return your vehicle to atrained and qualified Volvo service techni-cian for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. To

STARTING AND DRIVING
440meet seasonal air quality standards, some areas require the use of "oxygenated" fuel. Volvo permits the use of the following "oxy- genated" fuels. However, the specified octaneratings must still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred toas Ethyl alcohol, or "Gasohol". Ethers - MTBE/ETBE: Fuels containing up to 22% MTBE/ETBE by volume may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriorationand can damage critical parts in the fuel sys-tem. Such damage may not be covered underthe New Vehicle Limited Warranty.

NOTE
When switching to higher octane fuel or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticea-ble.
Fuel FormulationsDo not use gasoline that contains lead or man- ganese as a knock inhibitor, and do not uselead additives. Besides damaging the exhaustemission control systems on your vehicle, leadhas been strongly linked to certain forms ofcancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, takeprecautions. These may include: standing upwind away from the filler noz-zle while refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouthof the filler neck during refueling
wearing neoprene gloves while handling afuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze dur-ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.
WARNING
Never carry a cell phone that is
switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that could ignite gasoline fumes, resulting in fireand injury.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumesinside the vehicle, make sure the passengercompartment is ventilated, and immedi-ately return the vehicle to a trained andqualified Volvo service technician for cor-rection.
Demanding drivingIn demanding driving conditions, such as when towing a trailer or driving in hot weather or for prolonged periods at high altitudes, it may be a good idea to switch to a higher- octane fuel (AKI
21
91 or higher) or to switch to
another brand of gasoline in order to fully uti- lize the vehicle's engine capacity and optimizetraction.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.
