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 willlessen 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

NOTE
When switching to higher octane fuel or changing gasoline brands, it may be neces-sary to fill the tank more than once before adifference in engine operation is noticea-ble.
Fuel FormulationsDo not use gasoline that contains lead or man- ganese as a knock inhibitor, and do not uselead additives. Besides damaging the exhaustemission 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 linked tocertain forms of cancer. If you live in an areawhere you must fill your own gas tank, takeprecautions. These may include: standing upwind away from the filler noz-zle while refueling
refueling only at gas stations with vaporrecovery systems that fully seal the mouthof 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 in fireand injury.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumesinside the vehicle, make sure the passengercompartment is ventilated, and immedi-ately return the vehicle to a trained andqualified Volvo service technician for cor-rection.
Demanding drivingIn demanding driving conditions, such as when towing a trailer or driving in hot weather or for prolonged periods at high altitudes, it may be a good idea to switch to a higher- octane fuel (AKI
15
91 or higher) or to switch to
another brand of gasoline in order to fully uti- lize the vehicle's engine capacity and optimizetraction.

Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involvingthe electrical, fuel or distributor ignitionsystems, may cause unusually high three-way catalytic converter temperatures. Donot continue to operate your vehicle if youdetect engine misfire, noticeable loss ofpower or other unusual operating condi-tions, such as engine overheating or back-firing. A properly tuned engine will helpavoid malfunctions that could damage thethree-way catalytic converter.
Do not park your vehicle over combustiblematerials, such as grass or leaves, whichcan come into contact with the hotexhaust system and cause such materialsto ignite under certain wind and weatherconditions.
Excessive starter cranking (in excess ofone minute), or an intermittently firing orflooded engine can cause three-way cata-lytic converter or exhaust system over-heating.
Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehicle maybe illegal and can cause three-way cata-lytic converter or exhaust system over-heating. This includes: altering fuel injec- tion settings or components, alteringemission system components or locationor removing components, and/or repeateduse of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxy- gen content of the exhaust gases. Readings are fed into a control module that continuouslymonitors engine functions and controls fuelinjection. The ratio of fuel to air into the engineis continuously adjusted for efficient combus-tion to help reduce harmful emissions.

WARNING
High voltage may be dangerous if handled incorrectly. Do not touch anything on bat-teries that is not clearly described in thisOwner's Manual. Never use a 48 V support battery to jump start the vehicle.
External electrical equipment may notunder any circumstance be connectedto the 48 V battery.
Only a workshop may replace or per-form service on the 48 V battery – anauthorized Volvo workshop is recom-mended.
WARNING
PROPOSITION 65 WARNING!
Battery
posts, terminals, and related accessories contain lead and lead compounds, chemi-cals known to the state of California tocause cancer and reproductive harm. Washhands after handling.
WARNING
Batteries generate hydrogen gas, which is flammable and explosive.
Do not connect the jumper cable toany part of the fuel system or to anymoving parts. Avoid touching hotmanifolds.
Battery fluid contains sulfuric acid. Donot allow battery fluid to contact eyes,skin, fabrics or painted surfaces.
If contact occurs, flush the affectedarea immediately with water. Obtainmedical help immediately if eyes areaffected.
Never expose the battery to open flameor electric spark. Do not smoke nearthe battery. Failure to follow theinstructions for jump starting can leadto injury.
NOTE
If the starter battery has been discharged to the extent that the vehicle does not havenormal electrical functions and the enginemust then be jump-started with an externalbattery or a battery charger, the Start/Stopfunction may remain activated. If the Start/Stop function shortly thereafter auto-stopsthe engine, there is a huge risk that auto-start of the engine will fail due to insuffi-cient battery capacity since the battery hadnot had time to recharge. If the vehicle has been jump-started or if there has not been enough time for thebattery to be charged with a batterycharger, the Start/Stop function should betemporarily deactivated until the batteryhas been recharged by the vehicle. At anambient temperature of about +15°C(about 60°F), the battery must be chargedby the vehicle for at least one hour. Atlower ambient temperatures, the chargingtime can increase to 3-4 hours. It is advisa-ble to charge the battery with an externalbattery charger.

Towing using a towline
This section refers to one vehicle being towed behind another using a towline.
Before towing another vehicle, check applica- ble speed limit regulations.
Preparations and towing
CAUTION
Vehicles with the small gear selector can- not shift out of the P position when theengine is off. Contact an authorized Volvoworkshop or a professional towing com-pany for assistance towing the vehicle.
CAUTION
Note that the vehicle must always be towed with the wheels rolling forward.
Do not tow a vehicle with automatictransmission at a speed greater than80 km/h (50 mph) or for a distancegreater than 80 km (50 miles).
WARNING
Ignition mode
II must be active – all
airbags are deactivated in ignition mode I.
Always have the remote key in thevehicle when it is towed.
WARNING
The brake and steering servos do not work when the engine is off – it takesabout 5 times more pressure on the brakepedal and steering requires much moreeffort than normal.
1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.
3. Put the vehicle in ignition mode II – with-
out pressing the brake pedal, turn the start knob clockwise and hold it there for about4 seconds. Release the knob, which willautomatically return to its original position.
4. Move the gear selector to neutral (N) and release the parking brake. If the battery charge level is too low, it may not be possible to release the parkingbrake. Connect an auxiliary battery to thevehicle if the battery is discharged.
> The towing vehicle can now start driv-ing.

can then be removed. 4. Screw the towing eyelet into place as far
as possible.Fasten the eyelet securing by, for example, inserting a lug wrench * through it and
using this as a lever.
CAUTION
It is important that the towing eye is screwed in securely as far as possible.
To consider before using the towing eyelet
In certain conditions, the towing eyelet may be used to pull the vehicle onto a flat-bed tow truck. The vehicle's position andground clearance determines if this is pos-sible.
If the incline of the tow truck is too steepor if the ground clearance under the vehi-cle is insufficient, attempting to pull it up using the towing eyelet may result in dam-age.
If necessary, lift the vehicle using the towtruck's lifting device instead of using thetowing eyelet.
WARNING
No person or object should be behind the tow truck when the vehicle is lifted ontothe bed of the truck.
CAUTION
The towing eyelet is only intended for tow- ing on roads – not for pulling vehicles fromditches or any similar purpose involvingsevere strain. Call a tow truck for profes-sional assistance.
Removing the towing eyelet–Unscrew the towing eyelet after use and return it to its storage location in the foamblock. Replace the cover on the bumper.
