Winter driving
It is important to check the vehicle before driving in cold/snowy conditions to make sure it can bedriven safely.
Before the cold season arrives:
• Make sure the engine coolant contains 50% antifreeze. This mixture helps protect theengine from frost erosion down toapprox. -35 °C (-31 °F). Do not mix differenttypes of antifreeze as this could pose ahealth risk.
• Keep the fuel tank well filled to prevent con-densation from forming.
• Check the viscosity of the engine oil. Oil withlow viscosity (thinner oil) improves cold-weather starting and reduces fuel consump-tion when driving with a cold engine.
CAUTION
Low-viscosity oil should not be used with hard driving or in hot weather.
•
Check the condition and charge level of the start battery. Cold weather places greaterdemands on the start battery and reduces itscapacity.
• Use washer fluid containing antifreeze tohelp prevent ice from forming in the washerfluid reservoir.
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.

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.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine 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 with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content 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.

Battery drain The electrical functions in the vehicle drain the battery to varying degrees. Avoid using ignitionmode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain power from the electrical system. Do not usefunctions that use a lot of electrical current whenthe engine is turned off. Examples of such func-tions are:
• blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message isshown in the driver display. The vehicle's energy-saving function will then turn off or reduce certainfunctions, such as the blower and/or the audio system.
–Charge the battery by starting the engine and let it run for at least 15 minutes (drivingcharges the battery faster than letting theengine idle).
