Driving through water
The vehicle should be driven with extreme caution if it is necessary to drive throughstanding water. The vehicle can be driven through water up to a depth of approximately 11 in. (30 cm) atwalking speed to help prevent water fromentering the differential and the transmission.Water reduces the oil's lubricating capacityand may shorten the service life of thesecomponents.
• Take particular care when driving through flowing water.
• Clean the electrical connections for trailerwiring after driving in mud or water.
• When driving through water, maintain lowspeed and do not stop in the water.WARNING
•Avoid driving through standing or rushing water. Doing so can be dan-gerous and it may also be difficult todetermine the actual depth of thewater.
• If water cannot be avoided, after driv-ing through the water, press lightly onthe brake pedal to ensure that thebrakes are functioning normally. Wateror mud can make the brake liningsslippery, resulting in delayed brakingeffect.
CAUTION
•
Engine damage will occur if water is drawn into the air cleaner.
• If the vehicle is driven through waterdeeper than approximately 11 in.(30 cm), water may enter the differen-tial and the transmission. This reducesthe oil's lubricating capacity and mayshorten the service life of these com-ponents.
• Damage to any components, theengine, transmission, turbo-charger,differential or its internal componentscaused by flooding, vapor lock orinsufficient oil is not covered underwarranty.
• Do not allow the vehicle to stand inwater up to the door sills longer thanabsolutely necessary. This could resultin electrical malfunctions.
• If the engine has been stopped whilethe vehicle is in water, do not attemptto restart it. Have the vehicle towedout of the water.

Engine and cooling system
Under special conditions, for example when driving in hilly terrain, extreme heat or withheavy loads, there is a risk that the engine andcooling system will overheat. Proceed as follows to avoid overheating the engine. •Maintain a low speed when driving with a trailer up long, steep hills. For informa-tion, see Towing a trailer (p. 281)
• Do not turn the engine off immediatelywhen stopping after a hard drive.
WARNING
The cooling fan may start or continue to operate (for up to 6 minutes) after theengine has been switched off.
•
Remove any auxiliary lights from in front of the grille when driving in hot weatherconditions.
• Do not exceed engine speeds of4500 rpm if driving with a trailer in hillyterrain. The oil temperature could becometoo high.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
• When the engine is not running, avoid using ignition mode
II. Many electrical
systems (the audio system, the optionalnavigation system, power windows, etc)will function in ignition modes 0 and I.
These modes reduce drain on the battery.
• Please keep in mind that using systems,accessories, etc., that consume a greatdeal of current when the engine is notrunning could result in the battery beingcompletely drained. Driving or having theengine running for approximately15 minutes will help keep the batterycharged.
• The optional 12-volt socket in the cargoarea (p. 141) area provides electrical cur-rent even with the ignition switched off,which drains the battery.
Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo serv-ice technician before driving long distances.Your retailer will also be able to supply youwith bulbs, fuses, spark plugs and wiperblades for your use in the event that problemsoccur. As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and that fuel consumption is normal.
• Check for fuel, oil, and fluid leakage.
• Have the transmission oil level (p. 377)checked.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (the spare tire aswell), and replace those that areworn (p. 290). Check tire pres-sure (p. 297).
• The brakes, front wheel alignment, andsteering gear should be checked by atrained and qualified Volvo service techni-cian only.
• Check all lights, including high beams.
• Reflective warning triangles are legallyrequired in some states/provinces.
• Have a word with a trained and qualifiedVolvo service technician if you intend to

drive in countries where it may be difficult to obtain the correct fuel.
• Consider your destination. If you will bedriving through an area where snow or iceare likely to occur, consider snowtires (p. 305).

Driving in cold weather
Check your vehicle before the approach of cold weather. The following advice is worth noting:
• Make sure that the engine cool- ant (p. 331) contains 50 percent anti-freeze. Any other mixture will reducefreeze protection. This gives protectionagainst freezing down to –31 °F (–35 °C).The use of "recycled" antifreeze is notapproved by Volvo. Different types ofantifreeze must not be mixed.
• Volvo recommends using only genuineVolvo antifreeze in your vehicle's radiator.
• Try to keep the fuel tank well filled – thishelps prevent the formation of condensa-tion in the tank. In addition, in extremelycold weather conditions it is worthwhileto add fuel line de-icer before refueling.
• The viscosity of the engine oil is impor-tant. Oil with low viscosity (thinner oil)improves cold-weather starting as well asdecreasing fuel consumption while theengine is warming up. Full synthetic0W-30 oil is recommended for driving inareas with sustained low temperatures.
• The load placed on the battery is greaterduring the winter since the windshieldwipers, lighting, etc., are used moreoften. Moreover, the capacity of the bat-tery decreases as the temperature drops.In very cold weather, a poorly chargedbattery can freeze and be damaged. It is therefore advisable to check the state ofcharge more frequently and spray an anti-rust oil on the battery posts.
• Volvo recommends the use of snow tireson all four wheels for winter driving, seeSnow tires/studded tires (p. 305).
• To prevent the washer fluid (p. 344)reser-voir from freezing, add washer solventscontaining antifreeze. This is importantsince dirt is often splashed on the wind-shield during winter driving, requiring thefrequent use of the washers and wipers.Volvo Washer Solvent should be dilutedas follows: Down to 14 °F (–10 °C): 1 partwasher solvent and 4 parts water Downto 5 °F (–15 °C): 1 part washer solventand 3 parts water Down to 0 °F (–18 °C):1 part washer solvent and 2 parts waterDown to –18 °F (–28 °C): 1 part washersolvent and 1 part water.
• Use Volvo Teflon Lock Spray in the locks.
• Avoid using de-icing sprays as they cancause damage to the locks.

Refueling – fuel requirements
Volvo recommends the use of detergent gas- oline to control engine deposits.
Deposit control gasoline (detergentadditives)
Detergent gasoline is effective in keepinginjectors and intake valves clean. Consistentuse of deposit control gasolines will helpensure good drivability and fuel economy. Ifyou are not sure whether the gasoline con-tains deposit control additives, check with theservice station operator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline belabeled "UNLEADED". Only these pumpshave nozzles which fit your vehicle's fillerinlet. It is unlawful to dispense leaded fuelinto a vehicle labeled "unleaded gasolineonly". Leaded gasoline damages the three-way catalytic converter and the heated oxy-gen sensor system. Repeated use of leadedgasoline will lessen the effectiveness of theemission control system (p. 279) and could result in loss of emission warranty coverage.State and local vehicle inspection programswill make detection of misfueling easier, pos-sibly resulting in emission test failure for mis-fueled vehicles.
NOTE
Some U.S. and Canadian gasolines con- tain an octane enhancing additive calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator light)located on your instrument panel maylight. If this occurs, please return yourvehicle 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 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. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel.
Volvo allows the use of the following "oxy-genated" fuels; however, the octane rat-ings (p. 276) listed must still be met.
Alcohol – EthanolFuels containing up to 10% ethanol by vol- ume may be used. Ethanol may also be refer-red to as Ethyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.

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 ifyou detect engine misfire, noticeable lossof power or other unusual operating con-ditions, such as engine overheating orbackfiring. A properly tuned engine willhelp avoid malfunctions that could dam-age the three-way catalytic converter.
• Do not park your vehicle over combusti-ble materials, such as grass or leaves,which can 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 cat-alytic converter or exhaust system over-heating.
• Remember that tampering or unauthor-ized modifications to the engine, theEngine Control Module, or the vehiclemay be illegal and can cause three-waycatalytic converter or exhaust systemoverheating. This includes: altering fuelinjection settings or components, alteringemission system components or location or removing components, and/or repea-ted use 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. Readingsare fed into a control module that continu-ously monitors engine functions and controlsfuel injection. The ratio of fuel to air into theengine is continuously adjusted for efficientcombustion to help reduce harmful emis-sions.

Economical driving
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions.
Economical driving conserves natural resources
Observe the following rules:
• Bring the engine to normal operating tem- perature as soon as possible by drivingwith a light foot on the accelerator pedalfor the first few minutes of operation. Acold engine uses more fuel and is subjectto increased wear.
• Whenever possible, avoid using the vehi-cle for driving short distances. This doesnot allow the engine to reach normaloperating temperature.
• Drive carefully and avoid rapid accelera-tion and hard braking.
• Use the transmission's Drive (
D) position
as often as possible and avoid using kick-down.
