Slippery driving conditionsFor optimal traction and roadholding, Volvo rec- ommends using snow tires on all wheels when-ever there is a risk of snow or ice on the road.
NOTE
Certain countries require use of winter tires by law. Not all countries permit the use ofstudded tires.
Practice driving on slippery surfaces under con- trolled conditions to learn how the vehicle reacts.

Driving through standing water
Driving the vehicle through a deep pool of stand- ing water on a water-covered roadway is calledfording. This must be done with great caution.
The vehicle can be driven through water up to a depth of 25 cm (9.8 in) at no more than walkingspeed. Be particularly careful when drivingthrough flowing water. When driving through standing water, drive slowly and do not stop the vehicle. When you havepassed the water, press lightly on the brake pedaland check that the brakes are functioning prop-erly. Water, mud, slush, etc. can make the brakelinings slippery, resulting in delayed brakingeffect.
• If the vehicle is equipped with contacts for anelectric heater or trailer coupling, clean theseafter driving in water or mud.
• Do not allow the vehicle to stand in water upto the sills any longer than absolutely neces-sary. This could result in electrical malfunc-tions.
CAUTION
• Engine damage could occur if water enters the air cleaner.
• If water enters the transmission, the lubri-cating ability of the oils is reduced andthe service life of these systems is short-ened.
• Damage to any component, engine,transmission, turbocharger, differential orits internal components caused by flood-ing, vapor lock or insufficient oil is notcovered under warranty.
• If the engine stalls while the vehicle is inwater, do not attempt to restart it. Havethe vehicle towed out of the water to aworkshop. An authorized Volvo workshopis recommended. Risk of engine failure.

•Opening/closing the fuel filler door (p. 427)
Fuel 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 fuel injector cleaning systems, e.g. do not adddetergent additives to gasoline before or afterrefueling.
Unleaded fuelAll 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 an octane 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.

Preparations and towing
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 air-
bags are deactivated in ignition mode I.
• Always have the remote key in the vehicle 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 more effortthan normal. 1. Turn on the hazard warning flashers.
2. Attach the towline to the towing eyelet.3.
Put the vehicle in ignition mode II – without
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 parking brake.Connect an auxiliary battery to the vehicle ifthe battery is discharged.
> The towing vehicle can now start driving.
5. Keep the towline taut when the towing vehi- cle slows down by applying light pressure to the brake pedal. This will help avoid jarringmovements.
6. Be prepared to apply the brakes to stop the vehicle.
Jump startingDo not tow the vehicle to start the engine. Use anauxiliary battery if the start battery's charge levelis so low that the engine cannot be started.

Emission inspection readiness
How do states use OBD II for emission
inspections?
Many states connect a computer directly to a vehicle's OBD II system. The inspector can thenread "faults." In some states, this type of inspec-tion has replaced the tailpipe emission test.
How can my vehicle fail OBD II emission
inspection?
Your vehicle can fail OBD II emission inspection for any of the following reasons:
• If your Check Engine (MIL) light is lit, yourvehicle may fail inspection.
• If your vehicle's Check Engine light was lit,but went out without any action on your part,OBD II will still have a recorded fault. Yourvehicle may pass or fail, depending on theinspection practices in your area.
• If you had recent service that required dis-connecting the battery, OBD II diagnosticinformation may be incomplete and "notready" for inspection. A vehicle that is notready may fail inspection.
How can I prepare for my next OBD II
emission inspection?
• If your Check Engine (MIL) light is lit - or was lit but went out without service, have your vehicle diagnosed and, if necessary, servicedby a qualified Volvo technician.
• If you recently had service for a lit CheckEngine light, or if you had service thatrequired disconnecting the battery, a periodof driving is necessary to bring the OBD IIsystem to "ready" for inspection. Two half-hour trips of mixed stop-and-go/highwaydriving are typically needed to allow OBD II toreach readiness. Your Volvo retailer can pro-vide you with more information on planning atrip.
• Maintain your vehicle in accordance with yourvehicle's maintenance schedule.
Owner maintenancePeriodic maintenance requirements and intervalsare described in your vehicle's Warranty andService Records Information booklet. The following points can be carried out between the normally scheduled maintenance services.
Each time the car is refueled:
•Check the engine oil level.
• Clean the windshield, windshield wipers, headlights, and taillights.
Monthly:
• Check cold tire pressure in all tires. Inspect the tires for wear.
• Check that engine coolant and other fluidlevels are between the indicated "min" and"max" markings.
• Clean interior glass surfaces with a glasscleaner and soft paper towels.
• Wipe driver information displays with a softcloth.
• Visually inspect battery terminals for corro-sion. Corrosion may indicate a loose terminalconnector, or a battery near the end of itsuseful service life. Consult your Volvo retailerfor additional information.
As needed:
Wash the car, including the undercarriage, to reduce wear that can be caused by a buildup ofdirt, and corrosion that can be caused by salt res-idues. Clean leaves and twigs from air intake vents at the base of the windshield, and from other placeswhere they may collect.

MAINTENANCE AND SERVICE
560If the engine oil is not checked regularly and the level becomes low, this could cause seriousengine damage.
CAUTION
To satisfy the requirements for the engine's service intervals, all engines are factory-filledwith a specially adapted synthetic engine oil.Great care has been put into the choice of oil,with consideration given to service life, starta-bility, fuel consumption and environmentalimpact. For the recommended service intervals to apply, an approved engine oil must be used.Only use the prescribed oil grade to top off orchange the oil. Otherwise, there is a risk ofthe vehicle's service life, startability, fuel con-sumption and environmental impact beingaffected. Failure to use engine oil of the prescribed grade and viscosity could cause damage toengine-related components. Volvo Car Corpo-ration disclaims warranty liability for such typeof damage. Volvo recommends entrusting oil changes to an authorized Volvo workshop.
Volvo uses different systems to warn if the oil level is too low/high or the oil pressure is low. Onengine variants with an oil pressure sensor, a
warning symbol is displayed in the instrument panel when oil pressure is low
. On engine
variants with an oil level sensor, the
warn-
ing symbol in the instrument panel and display messages are used to alert the driver. Someengine variants have both systems. Contact aVolvo retailer for more information. Change the engine oil and oil filter according to the schedule specified in the Warranty and Main-tenance Records Information booklet. Oils of ahigher grade than that specified may be used. Ifthe vehicle is driven in adverse conditions, Volvorecommends using an oil with a higher gradethan that specified.
