Starting the engine – Flexifuel
Flexifuel engines can be driven on 95 octane unleaded petrol and bioethanol E85. Theengine is started in the same way as in a pet-rol-driven car.
Engine block heater*
Electrical input to the engine block heater.
Cars intended for E85 have an electric engine block heater. Starting and driving with a pre-heated engine means significantly reducedemissions and reduced fuel consumption. Forthis reason you should aim to use the engineblock heater throughout the winter months. • In outside temperatures between +5 °C and -10 °C, the electric engineblock heater should be activated for atleast 1 hour.
• In outside temperatures between-10 °C and -20 °C, the electric engine block heater should be activated for atleast 2 hours.
• In outside temperatures lower than-20 °C, the electric engine block heatershould be activated for at least 3 hours.
WARNING
The engine block heater is powered by high voltage. Fault tracing and repair of anelectric engine block heater and its electri-cal connections must only be carried outby a workshop - an authorised Volvo work-shop is recommended.
NOTE
Points to remember for carrying reserve fuel:
• In the event of stalling due to an empty fuel tank, bioethanol E85 from areserve fuel can may make the enginedifficult to start in extreme cold. This isavoided by filling the reserve fuel canwith 95 octane petrol.
For more information on Flexifuel's bioethanol E85 fuel, see Fuel - bioethanol E85 (p. 304).
In the event of starting difficultiesIf the engine does not start at the first startattempt: •
Make further attempts to start with the START/STOP ENGINE
button.
• Check that the engine block heater hasbeen activated and, where appropriate,activate it for the time specified above.
IMPORTANT
If the engine does not start despite repea- ted start attempts, you are recommendedto contact an authorised Volvo workshop.
Fuel adaptationFlexifuel engines can be driven on both 95 octane unleaded petrol and bioethanol E85.Both fuels are filled in the common fuel tankso that any variations of mixing ratiosbetween these two fuels is possible. If the fuel tank is filled with petrol after the car has been driven on bioethanol E85 (or viceversa) then the engine may run slightlyunevenly for a time. For this reason it isimportant to allow the engine to accustomitself (adapt) to the new fuel mixture. Adaptation takes place automatically when the car is driven for a short period at an evenspeed.

The foot brake can be released before setting off or reversing uphill - the HSA (Hill StartAssist) function means that the car does notroll backwards. The function means that the pedal pressure in the brake system remains for several secondswhile the driver's foot is moved from brakepedal to accelerator pedal. The temporary braking effect releases after several seconds or when the driver acceler-ates.

Start/Stop*
Some engine and gearbox combinations come fitted with a Start and Stop functionwhich engages in the event of e.g. stationarytraffic or waiting at traffic lights - the engine isthen switched off temporarily and restartsautomatically when the journey is due to con-tinue. Environmental care is one of Volvo Car Cor- poration's core values which guides all ouractivities. This target orientation has resultedin several separate energy-saving functions ofwhich Start/Stop is one, all with the collectivetask of reducing fuel consumption, which inturn helps to reduce exhaust emissions.
General information about Start/Stop
The engine is switched off - it becomes quieter and cleaner.

ECO*
ECO is an innovative Volvo function for auto- matic-gearbox cars, capable of reducing fuelconsumption by up to 5%, depending on thedriver's driving style. The function gives thedriver the option of a more active environ-mentally conscious way of driving.
GeneralThe following are changedupon activation of the ECOfunction:
• Gearbox gearshift points.
• Engine management and response from the accelerator pedal.
• Start/Stop function - the engine can alsoauto-stop before the car has stopped tobeing fully stationary.
• The Eco Coast function is activated -engine braking ceases.
• Climate control system settings - someelectricity consumers are deactivated oroperate at reduced power.
NOTE
When the ECO function is activated, sev- eral parameters in the climate control sys-tem's settings are changed, and severalelectricity consumer functions are reduced- a press of the
AC button resets the cli-
mate control system, but then withreduced AC function.
ECO - Operation
ECO On/Off
ECO symbol
The ECO function is deactivated when the engine is switched off, and must therefore beactivated after each time the engine isstarted. There are exceptions for certainengines. However, it is easily verified bymeans of both the combined instrument panel
ECO symbol and the ECO button lamp
illuminating when the function is activated.
ECO function On or OffDisengaged ECO function is indicated by the combined instrument panel
ECO sym-
bol and the ECO button lamp extinguishing. The function isthen switched off until it isreactivated with the ECObutton.
Eco Coast - FunctionThe Eco Coast subfunction means in practice that engine braking is deactivated, meaning inturn that the car's kinetic energy is used tocoast for longer distances. When the driverreleases the accelerator pedal the gearbox isautomatically disengaged from the enginewhose speed is reduced to idling speed withminimum consumption. This function is intended for use in the event of an anticipated reduction in speed, e.g. toroll forward to an intersection or a red light. Eco Coast enables proactive driving where the driver can use the so-called "Pulse &Glide" technique and a minimum of braking. Combination On and Off A combination of Eco Coast and temporarily deactivated ECO function can also collec-tively contribute to reduced consumption.Accordingly:
• Active Eco Coast: Long coasting
without
engine braking = Low consumption

Before a long journey
Before a long journey, it makes good sense to go through the following points: •Check that the engine is working normally and that fuel consumption (p. 403) is nor-mal.
• Make sure that there are no leaks (fuel, oilor other fluid).
• Check all bulbs and tyre tread depths.
• Carrying a warning triangle (p. 329) is alegal requirement in certain countries.

Winter driving
For winter driving it is important to perform certain checks in order to ensure that the carcan be driven safely. Check the following in particular before the cold season:
• The engine coolant (p. 349) must contain at least 50% glycol. This mixture protectsthe engine against frost erosion down toapproximately –35 °C. To achieve opti-mum antifreeze protection, different typesof glycol must not be mixed.
• The fuel tank must be kept filled to pre-vent condensation.
• Engine oil viscosity is important. Oils withlower viscosity (thinner oils) facilitate star-ting in cold weather and also reduce fuelconsumption while the engine is cold. Formore information on suitable oils, seeEngine oil - adverse driving conditions (p.395).
IMPORTANT
Low viscosity oil must not be used for hard driving or in hot weather.
•The condition of the starter battery and charge level must be inspected. Coldweather places great demands on the starter battery and its capacity is reducedby the cold.
• Use washer fluid (p. 361) to avoid iceforming in the washer fluid reservoir.
To achieve optimum roadholding Volvo rec- ommends using winter tyres on all wheels ifthere is a risk of snow or ice.
NOTE
The use of winter tyres is a legal require- ment in certain countries. Studded tyresare not permitted in all countries.
Slippery driving conditionsPractise driving on slippery surfaces under controlled conditions to learn how the carreacts.

Filling with a fuel can14When filling with a fuel can, use the funnel located under the floor hatch in the cargoarea. The funnel is located by the spare wheelor in the well under the floor hatch. Make sure you insert the funnel's pipe firmly into the filler pipe. The filler pipe has an open-able cap and the funnel's pipe must bemoved past the cap before filling can begin.

Fuel - handling
Fuel of a lower quality than that recom- mended by Volvo must not be used as enginepower and fuel consumption is negativelyaffected.
WARNING
Always avoid inhaling fuel vapour and get- ting fuel splashes in the eyes. In the event of fuel in the eyes, remove any contact lenses and rinse the eyes in plentyof water for at least 15 minutes and seekmedical attention. Never swallow fuel. Fuels such as petrol, bioethanol and mixtures of them and die-sel are highly toxic and could cause per-manent injury or be fatal if swallowed.Seek medical attention immediately if fuelhas been swallowed.
WARNING
Fuel which spills onto the ground can be ignited. Switch off the fuel-driven heater before starting to refuel. Never carry an activated mobile phone when refuelling. The ring signal couldcause spark build-up and ignite petrolfumes, leading to fire and injury.
IMPORTANT
Mixing different types of fuel or the use of fuel not recommended invalidates Volvo'sguarantees, and any associated serviceagreement. This applies to all engines.NOTE: It does not apply to cars withengines that are adapted to run on ethanolfuel (E85).
NOTE
Extreme weather conditions, driving with a trailer or driving at high altitudes in combi-nation with fuel grade are factors thatcould affect the car's performance.

Fuel - petrol
Petrol is used as fuel. Petrol must fulfil the EN 228 standard. Most engines can be run with octane ratings of 95and 98 RON. Only in exceptional casesshould 91 RON be used.
• 95 RON can be used for normal driving.
• 98 RON is recommended for optimum performance and minimum fuel consump-tion.
When driving in temperatures above +38 °C, fuel with the highest possible octane rating isrecommended for optimum performance andfuel economy.
IMPORTANT
• Always refuel with unleaded petrol so as not to damage the catalytic con-verter.
• Do not use additives not recom-mended by Volvo.

Fuel - diesel
Diesel is used as fuel. Only use diesel fuel from well-known produc- ers. Never use diesel of dubious quality. Die-sel should fulfil the EN 590 or JIS K2204standards. Diesel engines are sensitive tocontaminants in the fuel, such as excessivelyhigh volumes of sulphur particles for exam-ple. At low temperatures (-6 °C to -40 °C), a par- affin precipitate may form in the diesel fuel,which may lead to ignition problems. Specialdiesel fuel designed for low temperaturesaround freezing point is available from themajor oil companies. This fuel is less viscousat low temperatures and reduces the risk ofparaffin precipitate. The risk of condensation in the fuel tank is reduced if the tank is kept well filled. Whenrefuelling, check that the area around the fuelfiller pipe is clean. Avoid spilling fuel onto thepaintwork. Wash off any spillage with deter-gent and water.
IMPORTANT
Only ever use fuel that fulfils the European diesel standard. The sulphur content must be a maximum of 50 ppm.
IMPORTANT
Diesel type fuels that must not be used:
• Special additives
• Marine diesel fuel
• Heating oil
• FAME 15
(Fatty Acid Methyl Ester) and
vegetable oil.
These fuels do not fulfil the requirements in accordance with Volvo recommendationsand generate increased wear and enginedamage that is not covered by the Volvowarranty.
Empty tankThe design of the fuel system in a diesel engine means that if the vehicle runs out offuel, the tank may need to be vented in theworkshop in order to restart the engine afterfuelling. Once the engine has stopped due to fuel starvation, the fuel system needs a fewmoments to carry out a check. Do this beforestarting the engine, once the fuel tank hasbeen filled with diesel:
1. Insert the remote control key in the igni- tion switch and push it in to the end posi-

tion, see Key positions (p. 70) for more information.
2. Press the START button without
depressing the brake and/or clutch pedal.
3. Wait approx. 1 minute.
4. To start the engine: Depress the brake and/or clutch pedal and then press the START button again.
NOTE
Before filling with fuel in the event of fuel shortage:
• Stop the car on as flat/level ground as possible - if the car is tilting there is arisk of air pockets in the fuel supply.
Draining condensation from the fuel filter
The fuel filter separates condensation from the fuel. Condensation can disrupt engineoperation. The fuel filter must be drained at the intervals specified in the Service and Warranty Bookletor if you suspect that the car has been filledwith contaminated fuel. For more information,see Volvo service programme (p. 340).
IMPORTANT
Certain special additives remove the water separation in the fuel filter.

Catalytic converters
The purpose of the catalytic converters is to purify exhaust gases. They are located closeto the engine so that operating temperature isreached quickly. The catalytic converters consist of a monolith (ceramic or metal) with channels. The channelwalls are lined with a thin layer of platinum/rhodium/palladium. These metals act as cata-lysts, i.e. they participate in and accelerate achemical reaction without being used upthemselves.
Lambda-sond TM
oxygen sensorThe Lambda-sond is part of a control systemintended to reduce emissions and improvefuel economy (see Fuel consumption andCO2 emissions (p. 403)). An oxygen sensor monitors the oxygen con- tent of the exhaust gases leaving the engine.This value is fed into an electronic systemthat continuously controls the injectors. Theratio of fuel to air directed to the engine iscontinuously adjusted. These adjustmentscreate optimal conditions for efficient com-bustion, and together with the three-way cat-alytic converter reduce harmful emissions(hydrocarbons, carbon monoxide and nitrousoxides).

Diesel particle filter (DPF)
Diesel cars are equipped with a particle filter, which results in more efficient emission con-trol. The particles in the exhaust gases are collec- ted in the filter during normal driving. So-called "regeneration" is started in order toburn away the particles and empty the filter.This requires the engine to have reached nor-mal operating temperature. Regeneration of the particle filter is automatic and normally takes 10-20 minutes. It maytake a little longer at a low average speed.Fuel consumption may increase slightly dur-ing regeneration.
Regeneration in cold weatherIf the car is frequently driven short distancesin cold weather then the engine does notreach normal operating temperature. Thismeans that regeneration of the diesel particlefilter does not take place and the filter is notemptied. When the filter has become approx. 80% full of particles, a yellow warning triangle isshown in the combined instrument panel, and the message
Soot filter full See manual is
shown in its information display. Start regeneration of the filter by driving the car until the engine reaches normal operatingtemperature, preferably on a main road or motorway. The car should then be driven forapproximately 20 minutes more.
NOTE
The following may arise during regenera- tion:
• a smaller reduction of engine power may be noticed temporarily
• fuel consumption may increase tem-porarily
• a smell of burning may arise.
When regeneration is complete the warning text is cleared automatically. Use the parking heater* in cold weather - the engine then reaches normal operating tem-perature more quickly.
IMPORTANT
If the filter is completely filled with parti- cles, it may be difficult to start the engineand the filter is non-functional. Then thereis a risk that the filter will need to bereplaced.
