Key blades
Your vehicle is equipped with two coded remote key transmitters with integrated igni-tion key blades called Key Integrated Remote(KIR). To unlock/lock the vehicle using the key blade:
1. If necessary, press button (1) to fold outthe key blade.
2. Insert the key blade in the driver's door lock and turn it once to unlock the driv-
er's door only .
3. Turn the key blade again (within 10 sec- onds) to unlock all doors and the tailgate. 4. Turn the key blade once in the opposite
direction to lock all doors and the tailgate.
Use the switch on the driver's door armrest to lock/unlock the vehicle from the inside.
WARNING
If the doors are locked while driving, this may hinder rapid access to the occupantsof the vehicle in the event of an accident.(Also see information on "Child safetylocks".)
NOTE
To help prevent accidentally locking the keys in the vehicle, the central locking sys-tem is designed to unlock the doors imme-diately if the key is left in the ignitionswitch, the vehicle is locked using the lockbutton on the door and the door is thenclosed. A sound from the lock will be audi-ble at this time. Please note that this function will not unlock the doors if the engine is running.
Immobilizer (start inhibitor)Each of the keys supplied with your vehicle contains a coded transmitter. The code in thekey is transmitted to an antenna in the igni-tion switch where it is compared to the code stored in the start inhibitor module. The vehi-cle will start only with a properly coded key. Each key has a unique code, which your Volvo retailer uses if new keys are required. Amaximum of six remote keys can be pro-grammed and used for one vehicle. If you misplace a key, take the other keys to an authorized Volvo retailer for reprogram-ming as an antitheft measure. If two of the keys to your vehicle are close together, e.g., on the same key ring, whenyou try to start the vehicle, this could causeinterference in the immobilizer system andresult in the vehicle not starting. If this shouldoccur, remove one of the keys from the keyring before trying to start the vehicle again.
NOTE
This device complies with part 15 of the FCC rules. Operation is subject to the fol-lowing condition: (1) This device may notcause harmful interference, and (2) thisdevice must accept any interferencereceived, including interference that maycause undesired operation.

Engine oil
Although some oil consumption occurs dur- ing normal engine operation, more oil is con-sumed when the engine is new as the internalparts generate higher friction while wearing-into each other. From the time the engine isnew until the first maintenance is performed,the oil consumption could be higher than nor-mal. For this reason, it is especially importantto check the oil regularly during this period,see page 222.
Fuel requirements
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gas- oline to control engine deposits. Detergentgasoline is effective in keeping injectors andintake valves clean. Consistent use of depositcontrol gasolines will help ensure good driva-bility and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station oper-ator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline be label-led "UNLEADED". Only these pumps havenozzles which fit your vehicle's filler inlet. It isunlawful to dispense leaded fuel into a vehiclelabelled "unleaded gasoline only". Leadedgasoline damages the three-way catalyticconverter and the heated oxygen sensor sys-tem. Repeated use of leaded gasoline willlessen the effectiveness of the emission con-trol system and could result in loss of emis-sion warranty coverage. State and local vehi-cle inspection programs will make detectionof misfueling easier, possibly resulting inemission test failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines con- tain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator lamp)located on your instrument panel maylight. If this occurs, please return yourvehicle to a trained and qualified Volvoservice technician for maintenance.
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. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxy- genated" fuels; however, the octane ratingslisted on page 139 must still be met. Alcohol – Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanolmay also be referred to as Ethyl alcohol, or"Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.

Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium for best per- formance, but using 87 octane 1
or above will
not affect engine reliability.
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
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.

WARNING
Driving with the tailgate open: Driving
with the tailgate open could lead to poi- sonous exhaust gases entering the pas-senger compartment.
• If the tailgate must be kept open for any reason, proceed as follows:
• Close the windows
• Set the ventilation system control to airflow to floor, windshield and side win-dows and blower control to its highestsetting.
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. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxy- genated" fuels; however, the octane ratingslisted on page 139 must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by vol- ume may be used. Ethanol may also be refer-red to as Ethyl 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 practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.
Weight distribution affects handlingAt the specified curb weight your vehicle hasa tendency to understeer, which means thatthe steering wheel has to be turned morethan might seem appropriate for the curva-ture of a bend. This ensures good stability and reduces the risk of rear wheel skid. Remember that theseproperties can alter with the vehicle load. The heavier the load in the cargo area, the less the tendency to understeer.
Handling, roadholdingVehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the recom- mended pressure according to the vehicleload. See "Tire pressure" section. Loads should be distributed so that capacity weight or maximum permissible axle loadsare not exceeded.
Conserving electrical currentKeep the following in mind to help minimizebattery drain:
• When the engine is not running, avoid turning the ignition key to position
II (see
page 145). Many electrical systems (theaudio system, the optional infotainment/navigation systems, power windows, etc)will function with the ignition key in posi-tion I. This position reduces drain on the
battery.
• Please keep in mind that using systems,accessories, etc that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.
NOTE
A warning message will be displayed in the text window in the instrument panel whenthe battery charge is low.
