Hybrid gauge
In Hybrid and Pure drive modes, the instrumentpanel will display a hybrid gauge, which can helpthe driver achieve optimal driving economy.
The hybrid gauge shows the ratio between theelectric motor's current power consumption andthe remaining available power. This information isshown in various ways.
Symbols in the hybrid gauge
Indicates the current available powerfrom the electric motor. A solid symbolindicates that the electric motor isbeing used.
A hollow symbol indicates that theelectric motor is not being used.
Indicates the power level when theinternal combustion engine starts. Asolid symbol indicates that the internalcombustion engine is being used.
Indicates the power level when theinternal combustion engine will start. Ahollow symbol indicates that the inter-nal combustion engine is not beingused.
Indicates that the hybrid battery isbeing charged, e.g. by lightly pressingthe brake pedal.
Driver-requested power
The hybrid gauge displays the amount of powerrequested (utilized) by the driver through pres-sure on the accelerator pedal. The higher thereading on the scale, the more power utilized inthe current gear. The mark between the lightningsymbol and the drop symbol indicates the pointat which the combustion engine will start.

CAUTION
Parts of the vehicle (e.g. engine, transmission,driveline, electrical components, etc.) can bedamaged if the vehicle is driven through waterhigher than its floor level. Damage to anycomponents caused by flooding, vapor lock orinsufficient oil is not covered under warranty.
If the engine stalls while the vehicle is inwater, do not attempt to restart it. Have thevehicle towed on the bed of a tow truck to aworkshop - an authorized Volvo workshop isrecommended.

CAUTION
Because it can be difficult to determine thewater depth, avoid driving through standing orrunning water.
When you have passed the water, press lightly onthe brake pedal and check that the brakes arefunctioning properly. Water, mud, slush, etc. canmake the brake linings slippery, resulting indelayed braking effect.
If the vehicle is equipped with a trailer couplingcontact, clean the contact after driving in water ormud.

Volvo recommends the use of detergent gaso-line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddriveability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.

NOTE
Volvo recommends not using external fuelinjector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.

Unleaded fuel
All Volvo vehicles have a three-way catalytic con-verter and must only use unleaded gasoline. USand Canadian regulations require that pumpsdelivering unleaded gasoline are labeled"UNLEADED". Only the nozzles of these pumpswill fit in your vehicle's fuel filler inlet. It is unlaw-ful to dispense leaded fuel into a vehicle labeled"unleaded gasoline only". Leaded gasoline dam-ages the three-way catalytic converter and theheated oxygen sensor system. Repeated use ofleaded gasoline will lessen the effectiveness of

the emission control system and could result inloss of emission warranty coverage. State andlocal vehicle inspection programs will makedetection of misfueling easier, possibly resultingin emission test failure for misfueled vehicles.

NOTE
Some U.S. and Canadian gasolines contain anoctane 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 permits the use of the following "oxygen-ated" fuels. However, the specified octane ratingsmust still be met.
Alcohol - Ethanol
Fuels containing up to 10% ethanol by volumemay be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol".
Ethers - MTBE/ETBE: Fuels containing up to22% MTBE/ETBE by volume may be used.

Methanol
Do 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.

TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER DetergentGasoline" where available to help maintainengine performance and reliability. TOP TIERDetergent Gasoline meets a new standard jointlyestablished by leading automotive manufacturesto meet the needs of today's advanced engines.Qualifying gasoline retailers (stations) will, inmost cases, identify their gasoline as having metthe "TOP TIER Detergent Gasoline" standards.

NOTE
Information about TOP TIER Detergent Gaso-line is available at www.toptiergas.com.

NOTE
When switching to higher octane fuel orchanging gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticeable.

Fuel Formulations
Do not use gasoline that contains lead or manga-nese as a knock inhibitor, and do not use leadadditives. Besides damaging the exhaust emis-sion control systems on your vehicle, lead hasbeen strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.Unburned benzene has been strongly linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, take pre-cautions. These may include:
standing upwind away from the filler nozzlewhile refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouth ofthe filler neck during refueling
wearing neoprene gloves while handling afuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze duringwinter 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 onwhile refueling your vehicle. If the phone rings,this may cause a spark that could ignite gaso-line fumes, resulting in fire and injury.
5AKI (Anti Knock Index) is an average value of RON (Research Octane Number) and MON (Motor Octane Number) - (RON)+(MON)/26For supplementary information - see the car's Service and Warranty Booklet.

WHEELS AND TIRES
* Option/accessory.549
Checking tire pressure
Correct inflation pressure helps improve drivingstability, save fuel and increase the service life ofthe tires.
Tire pressure decreases over time, which is nor-mal. Tire pressure also varies depending on theambient temperature. Driving on under-inflatedtires could cause the vehicle to overheat and leadto damage. Tire pressure affects traveling com-fort, road noise and driving characteristics.
Check the pressure in the tires every month. Usethe recommended inflation pressure for cold tiresfor optimal tire performance and wear. Under-inflated or over-inflated tires could cause uneventread wear.
Use an air pressure gauge and check the infla-tion pressure on all the tires, including the spare
tire4, at least once a month and before long trips.Volvo strongly recommends buying a reliable airpressure gauge, as the automatic gauges provi-ded at service stations may be inaccurate.

WARNING
Under-inflation is the most commoncause of tire failure and may result insevere tire cracking, tread separation, or"blow-out," with unexpected loss of vehi-cle control and increased risk of injury.
Under-inflated tires reduce the load car-rying capacity of your vehicle.

Cold tires
Inflation pressure should be checked when thetires are cold.
The tires are considered to be cold when theyhave the same temperature as the surrounding(ambient) air.
This temperature is normally reached after thevehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),the tires are considered to be warm. If you needto drive longer than that to inflate the tires, checkand record the inflation pressure of the tires firstand inflate accordingly when you arrive at thepump.
When the ambient temperature changes, so doesthe inflation pressure. A 10-degree temperaturedrop causes a corresponding drop in inflationpressure of 1 psi (7 kPa). Check the inflationpressure of the tires regularly and adjust to the
correct pressure, which can be found on the vehi-cle's tire information placard or certification label.
If you check inflation pressure when the tires arewarm, you should never release air. The tiresbecome warm after driving and it is normal forwarm tires to have an inflation pressure abovethe recommended pressure for cold tires. A warmtire with an inflation pressure equal to or underthe recommended pressure for cold tires couldbe significantly under-inflated.
