STARTING AND DRIVING
464Refueling is done as follows.
1. Turn off the engine and open the fuel filler
door.
NOTE
Refueling must be done within approximately 10 minutes of opening the fuel filler door.After this time, the valve opened by pushingthe button will close and it will no longer bepossible to refuel without the pump's nozzleswitching off. If the valve is closed before refueling is com- plete - press the button again and wait until the driver display shows the message
Fuel
tank Ready for refueling.
2. Select a fuel approved for use in the vehicle. For more information on approved fuels, see the section on "Gasoline".
3. Insert the pump's nozzle into the fuel filler pipe's opening. There are two flaps justinside the fuel filler pipe and the pump's noz-zle must push both of these flaps openbefore fuel can be added. 4. Avoid overfilling the tank. Do not press the
handle on the filler nozzle again after it hasinitially stopped pumping.
> The fuel tank is now filled.
NOTE
An over-full tank may overflow in hot weather.
CAUTION
Avoid spilling gasoline during refueling. In addition to causing damage to the environ-ment, gasolines containing alcohol can causedamage to painted surfaces, which may notbe covered under the New Vehicle LimitedWarranty.
Refueling from a fuel containerWhen filling from a fuel container, use the funnel provided in a foam block under the floor hatch inthe cargo compartment.
1. Open the fuel filler door.
2. Insert the funnel into the fuel filler pipe'sopening. There are two flaps just inside the fuel filler pipe and the tube section of thefunnel must push both of these flaps openbefore fuel can be added.

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

WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaustgases. If you ever smell exhaust fumes insidethe vehicle, make sure the passenger com-partment is ventilated, and immediately returnthe vehicle to a trained and qualified Volvoservice technician for correction.
Demanding drivingIn demanding driving conditions, e.g. when driving in a hot climates, driving with a trailer or drivingfor longer periods at higher altitudes (mountainlandscapes) than normal, it is recommended switching to a higher octane fuel than AKI 916
or
changing gasoline brand to take full advantage of your car's engine capacity and obtain the opti-mum driving force.

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.

Engine oil
For the recommended service intervals and war- ranties to be applied, an approved engine oilmust be used.
Volvo recommends:
If 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.

Automatic car washes The vehicle should be washed as soon as it becomes dirty. This makes the vehicle easier toclean because dirt does not attach as strongly. Italso reduces the risk of scratches and keeps thevehicle looking new.
Automatic car washesAn automatic car wash is a fast and easy way to keep your vehicle clean, but it does not reach allareas of the vehicle. For best results, Volvo rec-ommends hand washing your vehicle or supple-menting automatic car washes with a hand wash.
NOTE
Volvo recommends not washing the vehicle in an automatic car wash during the first fewmonths; the paintwork on new vehicles takessome time to fully harden.
CAUTION
Before driving the vehicle into a car wash, deactivate the Automatic Braking when Sta-tionary and Automatic Parking Brake Applica-tion functions. If the functions are not deacti-vated, the brake system will seize when thevehicle is stationary and the vehicle will not beable to roll.
CAUTION
For automatic car washes in which the vehicle is pulled forward on rolling wheels:
1. Before washing the vehicle, make surethat the automatic rain sensor is deacti- vated. If it is not deactivated and inadver-tently starts, the wiper arms could bedamaged.
2. To help prevent damage from the auto- matic car wash machinery, make surethat the door mirrors are folded in, anten-nas retracted or removed, and any auxili-ary lights secured.
3. Drive into the automatic car wash.
4. Turn off the "Automatic Braking when Stationary" function using the switch in the tunnel console.
5. Turn off the "Automatic Parking Brake Application" function in the center dis-play's Top view.
6. Turn off the engine by turning the start knob in the tunnel console clockwise.Hold the knob in position for at least2 seconds.
The vehicle is now ready for the automatic carwash.
CAUTION
The system will automatically change to P
mode if the above steps are not followed. In P
mode, the wheels are locked, which they should not be when the vehicle is beingwashed in a car wash.

Changing rear window wipers
The wiper blades help remove water from the windshield and rear window. Along with thewasher fluid, they clean the glass and helpimprove visibility while driving. The windshieldand rear window wiper blades can be replaced.
Changing rear window wipers
Lift the wiper arm from the window and pull the lower section of the blade to the right.
1. Grasp the center of the wiper blade and
lift it from the window to the stop position.
NOTE
When the wiper arm is halfway folded out, it will stop in a locking position that helps pre-vent the arm from falling back onto the rearwindow. The wiper arm must be pulled pastthe locking position stop in order to changethe wiper blade.
2. Grip the lower part of the blade and pull
to the right until the blade loosens from the arm.
3. Press the new wiper blade until it clicks into place. Check to make sure the blade issecurely in place.
4. Fold the wiper arm back toward the window.
CAUTION
Check the blades regularly. Neglected main- tenance shortens the life of the blades.
