Winter driving
Check your vehicle before the approach of cold weather.
The following advice is worth noting:
• Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture willreduce freeze protection. This gives protec-tion against freezing down to –31 °F(–35 °C). The use of "recycled" antifreeze isnot approved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuine Volvoantifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensationin the tank. In addition, in extremely coldweather conditions it is worthwhile to addfuel line de-icer before refueling.
• The viscosity of the engine oil is important.Oil with low viscosity (thinner oil) improvescold-weather starting as well as decreasingfuel consumption while the engine is warm-ing up. Full synthetic 0W-30 oil is recom-mended for driving in areas with sustainedlow temperatures.
• The load placed on the battery is greater dur-ing the winter since the windshield wipers,lighting, etc., are used more often. Moreover,the capacity of the battery decreases as thetemperature drops. In very cold weather, apoorly charged battery can freeze and bedamaged. It is therefore advisable to check the state of charge more frequently andspray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tires onall four wheels for winter driving.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt is oftensplashed on the windshield during winterdriving, requiring the frequent use of thewashers and wipers. Volvo Washer Solventshould be diluted as follows: Down to 14 °F(–10 °C): 1 part washer solvent and 4 partswater Down to 5 °F (–15 °C): 1 part washersolvent and 3 parts water Down to 0 °F(–18 °C): 1 part washer solvent and 2 partswater Down to –18 °F (–28 °C): 1 partwasher solvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle inspection programs will make detection of mis-fueling easier, possibly resulting in emission testfailure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl(MMT). If such fuels are used, your EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician 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 laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxygen- ated" fuels; however, the octane ratings listedmust still be met.

Alcohol – Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

Use of AdditivesWith the exception of gas line antifreeze during winter months, do not add solvents, thickeners, orother store-bought additives to your vehicle'sfuel, cooling, or lubricating systems. Overuse maydamage your engine, and some of these additivescontain organically volatile chemicals. Do notneedlessly expose yourself to 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 gaso-line fumes, resulting in fire and injury.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.

Refueling from a service station pump
To refuel:
1. Open the fuel filler door. Do not refuel withthe engine running 1
2. Insert the pump's nozzle into the fuel filler pipe's opening as far as possible (see the
illustration).
3. Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle after it has stopped pumping. Too much fuel in the tankin hot weather conditions can cause the fuelto overflow. Overfilling could also cause dam-age to the emission control systems.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components

Charging the hybrid battery In addition to the conventional fuel tank, the XC90 T8 Twin Engine Plug-in Hybrid is alsoequipped with a rechargeable lithium-ion hybridbattery.
The hybrid battery is recharged using a charging cable located in a storage compartment underthe floor of the cargo area. See also the article"Charging cable."
WARNING
The hybrid electrical system in your vehicle uses high voltage electrical current. Any dam-age to this system or to the hybrid batterymay result in the danger of overheating, fire,or serious injury. If the vehicle is involved in acollision or is subjected to flooding, fires, etc.,have it inspected by a trained and qualifiedVolvo service technician. Prior to this inspec-tion, the vehicle should be parked outdoors ata safe distance from any building or poten-tially flammable materials.
The hybrid battery's charging time depends on the charging current used.

NOTE
The capacity of the hybrid battery diminishes somewhat with age and use, which couldresult in increased use of the gasoline engineand consequently, slightly higher fuel con-sumption.
Charging is indicated in three ways: •Charge module (the unit that is plugged into the wall socket): The blue indicator light onthe cable's charge module will flash red sev-eral times when the unit is plugged into awall socket while a safety check is being per-formed and will then glow steadily blue toindicate that the charger is ready to use.
• A green indicator light in the vehicle's charg-ing socket will flash green while the batteryis charging and will glow steadily green whenthe hybrid battery is fully charged. The blueindicator light in the charge module will alsoflash while charging is underway and willglow steadily blue when charging is comple-ted.
• A gauge in the instrument panel will alsoindicate the battery's charge level.
The hybrid battery charging process also charges the vehicle's start battery. If the hybrid battery's temperature is below – 13 ºF (–10 ºC) or above +104 ºF (+40 ºC), some
of the vehicle's functions may be reduced or not be available at all (e.g., drive mode may not be available). The electric motor cannot be used if the hybrid battery's temperature is too low or too high. If thePURE drive mode is selected, the gasolineengine will be used.Temperature controlDuring charging, if the temperature in the charg-ing cable becomes too high and reaches a criticallimit, charging will be interrupted.
CAUTION
If charging is interrupted repeatedly, have the charging cable and the vehicle's chargingsystem inspected by a trained and qualifiedVolvo service technician.
Charging using the gasoline engine
Current is generated to charge the hybrid battery, such as light braking and when engine braking on down-slopes
Using the
B gear mode when driving on down-
slopes will also recharge the hybrid battery. The hybrid battery can also be charged by the gasoline engine. During light braking, the batteryis recharged.

Available drive modes
HYBRID
This is the default mode. The vehicle normally starts in
Hybrid mode 4
. The
engine management system uses both the elec- tric motor and gasoline engine (separately or intandem) and calculates the optimal levels of per-formance, fuel consumption and comfort. Athigher speeds, ground clearance is reducedautomatically to help reduce wind resistance. The amount of driving done using only the elec- tric motor in
Hybrid mode is determined by the
hybrid battery's charge level and the need for heating/cooling in the passenger compartment. If sufficient electrical energy is available, only the electric motor will be activated when the driverpresses the accelerator pedal up to a certainlevel. Above this level, the gasoline engine willstart.The instrument panel gauge when both the electric motor and gasoline engine are being used
The long needle in the gauge indicates the amount of energy that the vehicle is currentlyusing. The short white line between the "light-ning" and "oil drop" symbols indicates theamount of energy available. See also the article"General information about the XC90 T8 TwinEngine Plug-in Hybrid" for additional information. The gasoline engine starts when the response required when the driver presses the acceleratorpedal cannot be provided by the electric motoralone. The gauge also indicates when the battery is being recharged (regenerated) during light brak-ing. See the article "Brakes" for additional infor-mation. When the hybrid battery's charge level is low, thegasoline engine will start more often to help con-serve electrical energy. Charge the battery withthe charging cable as soon as possible or switch to the
Save drive mode.
PURE
This mode activates the electric motor only with as low energy consumption as possible and thelowest possible carbon dioxide emissions. Ground clearance will be lowered to help reduce wind resistance and certain climate system func-tions will be reduced.
Pure mode is available when the hybrid battery is
sufficiently charged. If the level gets too low, the gasoline engine will start. The gasoline engine will also start: • If the vehicle's speed goes above approx. 75 mph (125 km/h)
• If the driver wants more response than theelectric motor alone can provide
• If factors such as cold weather, etc., affectthe system or components
To restart the climate system functions that have been reduced in the mode, press the,
AUTO or
defroster buttons.
4 Unless the vehicle was switched off in Off Road mode. If so, it will restart in Off Road mode.
