Brake Assist System The brake enhancing system, (BAS 3
), helps
increase braking force and can thereby reduce braking distance.
The system monitors the driver's braking hab- its and increases braking force when neces-sary. Braking force can be increased up to thepoint at which the ABS intervenes. The func-tion is deactivated when pressure on the brakepedal is decreased.

Preconditioning
Whenever possible, precondition the vehi- cle before driving by connecting thecharging cable to an electrical outlet.
Avoid parking the vehicle somewherewhere the interior will become too hot ortoo cold while the vehicle is parked. If pos-sible, park the vehicle in a climate-con-trolled garage.
During a short drive after passenger com-partment preconditioning, turn off thepassenger compartment fan or the airconditioning in a hot climate.
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 hybrid battery.
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 combustion engine unnecessarily. The electric motor is more effective than the combustion engine, 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.

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.

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.
To help prevent damage to the vehicle when driving through water:
Do not drive in water higher than the floorof the vehicle. If possible, check the depthof the water at its deepest point beforedriving through it. Be particularly carefulwhen driving through flowing water.
Always select the
Off Road drive mode
before driving in water to ensure the gaso- line engine is running.
Do not drive faster than walking speed.
Do not stop the vehicle in the water. Drivecarefully forward or back the vehicle out ofthe water.
Remember that waves created by passingvehicles could cause the water level to riseabove the vehicle's floor level.
Avoid driving through salt water to helpavoid the risk of corrosion.
CAUTION
Parts of the vehicle (e.g. engine, transmis- sion, driveline, electrical components, etc.)can be damaged if the vehicle is driventhrough water higher than its floor level.Damage to any components caused byflooding, vapor lock or insufficient oil is notcovered under warranty. If the engine stalls while the vehicle is in water, do not attempt to restart it. Havethe vehicle towed on the bed of a towtruck to a workshop - an authorized Volvoworkshop is recommended.
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.
When you have passed the water, press lightly on the brake pedal and check that the brakesare functioning properly. Water, mud, slush,etc. can make the brake linings slippery,resulting in delayed braking effect. If the vehicle is equipped with a trailer cou- pling contact, clean the contact after driving inwater or mud.

handle on the filler nozzle again after it has initially stopped pumping.
> The fuel tank is now filled.
NOTE
An over-full tank may overflow in hot weather.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol cancause damage to painted surfaces, whichmay not be covered under the New VehicleLimited Warranty.
Refueling from a fuel containerWhen filling from a fuel container, use the fun- nel provided in a foam block under the floorhatch in the cargo compartment.
1. Open the fuel filler door.
2. Insert the funnel into the fuel filler pipe'sopening. There are two flaps just inside the fuel filler pipe and the tube section ofthe funnel must push both of these flapsopen before fuel can be added.

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 will lessen 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
meet seasonal air quality standards, someareas 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.
