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 fuel
Each Volvo has a three-way catalytic converterand 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 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 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 volumemay be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol".
Ethers – MTBE: Fuels containing up to15% MTBE 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.

CAUTION
Avoid spilling gasoline during refueling. Inaddition 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. Certainengine 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
or location or removing components, and/orrepeated use of leaded fuel.

NOTE
Unleaded fuel is required for vehicles withthree-way catalytic converters.

Heated oxygen sensors
The heated oxygen sensors monitor the oxygencontent of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

WHEELS AND TIRES

14. Immediately drive the vehicle for approxi-mately 2 miles (3 km) at a maximum speedof 50 mph (80 km/h) to distribute the seal-ing compound in the tire. During the tire'sfirst revolution, some sealing compound mayspray out of the puncture hole.

WARNING
No one should stand closer to the vehiclethan approx. 7 ft (2 m) when it drives away tohelp avoid being sprayed with sealing com-pound.

CAUTION
If your vehicle is equipped with the Tire Pres-sure Monitoring System (TPMS), the use ofthe sealing compound may lead to incorrecttire pressure readings or in rare cases, dam-age to the tire pressure sensor. Use the tiresealing system to check and adjust the dam-aged tire's inflation pressure.

NOTE
•Safely stow the tire sealing system in aconvenient place as it will soon be usedagain to check the tire

CAUTION
•Not checking the oil level regularly canresult in serious engine damage if the oillevel becomes too low.
•Oil that is lower than the specified qualitycan damage the engine.
•Volvo does not recommend the use of oiladditives.
•Always add oil of the same type and vis-cosity as already used.
•Oil changes should be carried out by atrained and qualified Volvo service techni-cian.
•Using oil of higher than the specifiedquality is permitted and may be neces-sary for demanding driving.
Also, refer to the Warranty and Service Recordsinformation booklet for information on oil changeintervals and oil specifications.

It may be necessary to top up engine oil betweenregularly scheduled services.
No action is necessary until a message is dis-played in the instrument panel.
WARNING
•Do not allow oil to spill onto or come intocontact with hot exhaust pipe surfaces.
•If Engine oil level Service required isdisplayed, have the vehicle checked by atrained and qualified Volvo service techni-cian. The oil level may be too high.
Checking the oil level
The oil level can be checked inthe center display when theengine is not running.
From the center display'sHome view, swipe the screenfrom right to left to open Appview. Tap Car status and then tap Status toshow the oil level.
Oil level graphic in the center display
The oil level should be checked at regular inter-vals, particularly during the period up to the firstscheduled maintenance service.
If the oil level sensor indicates that the level istoo low, using the correct oil, top up with theamount of oil indicated as soon as possible.
6Models with an electronic oil level sensor do not have a dipstick.

NOTE
•The system cannot detect changes in theoil level immediately. The vehicle must bedriven approximately 20 miles (30 km) orhave been parked on level ground withthe engine off for 5 minutes before theoil level reading will be correct.
•If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked onan incline, etc.), No values available willbe displayed. This does not indicate aproblem with the oil level sensor.
