Introduction
Start/Stop is a function that is available with certain engines/transmissions. It temporarilyswitches off the engine when the vehicle isnot moving, for instance in heavy traffic or ata traffic light to help reduce fuel consumption.
Function and use
Start/Stop symbol in the instrument panel
Start/Stop button on the center console
Start/Stop is activated automatically each time the engine is started 1
. The symbol in the
instrument panel will be displayed for several seconds when the engine starts and the indi-cator light in the On/Off button will remainilluminated while the function is activated. All of the vehicle's systems will function while the engine is auto-stopped, although the function of certain systems may reduced atthis time. For example, blower speed andhigh infotainment system volume may bereduced to help conserve the battery'scapacity.
Auto-stopping the engineNormally, when Start/Stop is activated andthe brakes are applied until the vehicle comesto a standstill, the engine will auto-stop auto-matically
if the driver keeps the brake pedal
depressed .
To remind the driver that the enginehas been auto-stopped, theStart/Stop symbol will illuminate inthe instrument panel and remain on
until the engine restarts.
If the ECO function* (see page 128) is activated, theengine may auto-stop beforethe vehicle comes to a com-plete standstill.
Auto-starting the engineThe engine restarts as soon as the driver releases the brake pedal.
Deactivating Start/StopIn certain situations (e.g.,driving in heavy, stop-and-gotraffic), it may be preferableto deactivate Start/Stop. This is done by pressing the button in the center console.
The indicator light in the button will go out. Start/Stop will remain deactivated until the button is pressed again or until the engine isswitched off and restarted by the driver.
Hill Start Assist (HSA)When starting on steep hills, HSA (see page 121) retains pressure on the brake pedalfor several seconds after the pedal has beenreleased in order to keep the vehicle at astandstill. The brakes will be released afterseveral seconds or when the driver pressesthe accelerator pedal.

Before a long distance tripIt is always worthwhile to have your vehicle checked by a trained and qualified Volvoservice technician before driving long dis-tances. Your retailer will also be able to sup-ply you with bulbs, fuses, spark plugs andwiper blades for your use in the event thatproblems occur. As a minimum, the following items should be checked before any long trip:• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage
• Have the transmission oil level checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that are worn.Check tire pressures.
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to drive in countries where it may be difficultto obtain the correct fuel.
• Consider your destination. If you will bedriving through an area where snow or iceare likely to occur, consider snow tires.
Cold weather precautionsIf you wish to check your vehicle before the approach of cold weather, the followingadvice is worth noting:
• Make sure that the engine coolant con- tains 50 percent antifreeze. Any othermixture will reduce freeze protection. Thisgives protection against freezing down to–31 °F (–35 °C). The use of "recycled"antifreeze is not approved by Volvo. Dif-ferent types of antifreeze must not bemixed.
• Volvo recommends using only genuineVolvo antifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensa-tion in the tank. In addition, in extremelycold weather conditions it is worthwhileto add fuel line de-icer before refueling.
• The viscosity of the engine oil is impor-tant. Oil with low viscosity (thinner oil)improves cold-weather starting as well asdecreasing fuel consumption while theengine is warming up. Full synthetic0W-30 oil is recommended for driving inareas with sustained low temperatures. •
The load placed on the battery is greaterduring the winter since the windshieldwipers, lighting, etc., are used moreoften. Moreover, the capacity of the bat-tery decreases as the temperature drops.In very cold weather, a poorly chargedbattery can freeze and be damaged. It istherefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tireson all four wheels for winter driving, seepage 307.
• To prevent the washer fluid reservoir fromfreezing, add washer solvents containingantifreeze. This is important since dirt isoften splashed on the windshield duringwinter driving, requiring the frequent useof the washers and wipers. Volvo WasherSolvent should be diluted as follows:Down to 14 °F (–10 °C): 1 part washersolvent and 4 parts water Down to 5 °F(–15 °C): 1 part washer solvent and3 parts water Down to 0 °F (–18 °C):1 part washer solvent and 2 parts waterDown to –18 °F (–28 °C): 1 part washersolvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Vehicles equipped with the high perform- ance 4-cylinder engines (B4204T9 and B4204T10) require premium fuel 2
.
TOP TIER Detergent GasolineVolvo endorses the use of “TOP TIER Deter- gent Gasoline” where available to help main-tain engine performance and reliability. TOPTIER Detergent Gasoline meets a new stand-ard jointly established by leading automotivemanufactures to meet the needs of today’sadvanced engines. Qualifying gasoline retail-ers (stations) will, in most cases, identify theirgasoline as having met the “TOP TIER Deter-gent Gasoline” standards.
NOTE
Information about TOP TIER Detergent Gasoline is available atwww.toptiergas.com.
Demanding drivingIn demanding driving conditions, such as operating the vehicle in hot weather, towing atrailer, or driving for extended periods athigher altitudes than normal, it may be advis-able to switch to higher octane fuel (91 orhigher) or to change gasoline brands to fullyutilize your engine's capacity, and for thesmoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be nec-essary to fill the tank more than oncebefore a difference in engine operation isnoticeable.
Fuel FormulationsDo not use gasoline that contains lead as a knock inhibitor, and do not use lead addi-tives. Besides damaging the exhaust emis-sion 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 linkedto certain forms of cancer. If you live in anarea where you must fill your own gas tank,take precautions. These may include:
• standing upwind away from the filler noz- zle while refueling
• refueling only at gas stations with vaporrecovery systems that fully seal themouth of 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 infire and injury.
WARNING
Carbon monoxide is a poisonous, color- less, and odorless gas. It is present in allexhaust gases. If you ever smell exhaustfumes inside the vehicle, make sure thepassenger compartment is ventilated, andimmediately return the vehicle to a trainedand qualified Volvo service technician forcorrection.
Opening/closing the fuel filler door
The fuel filler door is located on the right rear fender (indicated by an arrow beside the fueltank symbol on the information display
)
With the ignition switched off, press and release the button on the lighting panel tounlock the fuel filler door. Please note that thefuel filler door will remain unlocked until thevehicle begins to move forward. An audibleclick will be heard when the fuel filler doorrelocks. • If you intend to leave your vehicle while it is being refueled, this feature enables youto lock the doors/trunk while leaving thefuel filler door unlocked.
• You can also keep the vehicle locked ifyou remain inside it during refueling. The central locking button does not lock thefuel filler door.
• Be sure the fuel filler door is not obstruc-ted and is completely closed after refuel-ing.
• Open the fuel filler cap slowly during hotweather.
Close the fuel filler door by pressing it; a click indicates that it is closed.
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.

Loads
Properly loading your vehicle will provide maximum return of vehicle design perform-ance. Before loading your vehicle, familiarize your- self with the following terms for determiningyour vehicle's weight ratings, with or withouta trailer, from the vehicle's Federal/CanadianMotor Vehicle Safety Standards (FMVSS/CMVSS) label, and the vehicle's tire informa-tion placard:
Curb weightThe weight of the vehicle including a full tankof fuel and all standard equipment. It doesnot include passengers, cargo, or optionalequipment.
Capacity weightAll weight added to the curb weight, includingcargo and optional equipment. When towing,trailer hitch tongue load is also part of cargoweight.
NOTE
For trailer towing information, please refer to the section "Towing a trailer" on page287.
Permissible axle weightThe 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.
Gross vehicle weight (GVW)The vehicle's curb weight + cargo + passen-gers.
NOTE
•The location of the various labels in your vehicle can be found on page366.
• A table listing important weight limitsfor your vehicle can be found on page369.
Steps for Determining Correct Load Limit
1. Locate the statement "the combined
weight of occupants and cargo should never exceed XXX pounds" on your vehi-cle's placard. 2. Determine the combined weight of the
driver and passengers that will be ridingin your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX kilo-grams or XXX pounds.
4. The resulting figure equals the available amount of cargo and luggage loadcapacity. For example, if the "XXX"amount equals 1400 lbs. and there will befive 150 lb. passengers in your vehicle,the amount of available cargo and lug-gage load capacity is 650 lbs. (1400 – 750 (5 × 150) = 650 lbs.)
5. Determine the combined weight of lug- gage and cargo being loaded on the vehi-cle. That weight may not safely exceedthe available cargo and luggage loadcapacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual 1
to deter-
mine how this reduces the available cargo and luggage load capacity of yourvehicle.

Washing the car
The following points should be kept in mind when washing and cleaning the car: •The car should be washed at regular intervals since dirt, dust, insects and tarspots adhere to the paint and may causedamage. To help prevent corrosion, it isparticularly important to wash the car fre-quently in the wintertime.
• Avoid washing your car in direct sunlight.Doing so may cause detergents and waxto dry out and become abrasive. To avoidscratching, use lukewarm water to softenthe dirt before you wash with a softsponge, and plenty of sudsy water.
• Bird droppings
: Remove from paintwork
as soon as possible. Otherwise the finishmay be permanently damaged.
• A detergent can be used to facilitate thesoftening of dirt and oil.
• Dry the car with a clean chamois andremember to clean the drain holes in thedoors and rocker panels.
• Tar spots can be removed with tarremover after the car has been washed.
• A stiff-bristle brush and lukewarm soapywater can be used to clean the wiperblades. Frequent cleaning of the wind-shield and wiper blades improves visibility considerably and also helps prolong theservice life of the wiper blades.
• Wash off the dirt from the underside(wheel housings, fenders, etc).
• In areas of high industrial fallout, morefrequent washing is recommended.
NOTE
When washing the car, remember to remove dirt from the drain holes in thedoors and sills.
CAUTION
• During high pressure washing, the spray mouthpiece must never becloser to the vehicle than 13" (30 cm).Do not spray into the locks.
• Dirt, snow, etc., on the headlights canreduce lighting capacity considerably.Clean the headlights regularly, forexample when refueling.
Special moonroof cautions:
• Always close the moonroof and sunshade before washing your vehicle.
• Never use abrasive cleaning agents onthe moonroof.
• Never use wax on the rubber sealsaround the moonroof.
Exterior componentsVolvo recommends the use of special clean- ing products, available at your Volvo retailer,for cleaning colored plastic, rubber, or orna-mental components such as chromed stripson the exterior of your vehicle. The instruc-tions for using these products should be fol-lowed carefully. Solvents or stain removersshould not be used.
CAUTION
•Avoid waxing or polishing plastic or rubber components
• Polishing chromed strips can wearaway or damage the surface
• Polishes containing abrasive sub-stances should not be used
Automatic car wash
•
We do NOT recommend washing your car in an automatic wash during the firstfew months (because the paint will nothave hardened sufficiently).
• An automatic wash is a simple and quickway to clean your car, but it is worthremembering that it may not be as thor-ough as when you yourself go over thecar with sponge and water. Keeping theunderbody clean is most important, espe-cially in the winter. Some automatic
