Volvo and the environment Volvo is committed to the well-being of its cus- tomers. As a natural part of this commitment, wecare about the environment in which we all live.Concern for the environment means an everydayinvolvement in reducing our environmentalimpact.
Volvo's environmental activities are based on a holistic view, which means we consider the over-all environmental impact of a product throughoutits complete life cycle. In this context, design, pro-duction, product use, and recycling are all impor-tant considerations. In production, Volvo haspartly or completely phased out several chemicalsincluding CFCs, lead chromates, asbestos, andcadmium; and reduced the number of chemicalsused in our plants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic converter with aLambda sond, now called the heated oxygen sen-sor, in 1976. The current version of this highlyefficient system reduces emissions of harmfulsubstances (CO, HC, NOx) from the exhaust pipeby approximately 95 – 99% and the search toeliminate the remaining emissions continues.Volvo is the only automobile manufacturer tooffer CFC-free retrofit kits for the air conditioningsystem of all models as far back as the 1975model 240. Advanced electronic engine controlsand cleaner fuels are bringing us closer to ourgoal. In addition to continuous environmental refinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in the work to lessen the car's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
• Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• Drive at a constant speed whenever possible.
• See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
• Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
• When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

CAUTION
•Use ample washer fluid when washing the windshield. The windshield should bethoroughly wet when the wipers are inoperation.
• Avoid using the washers if the fluid reser-voir is frozen or empty to help avoid dam-age to the pump.
When the washing system is used, the length of time that the windshield washers operatedepends on the ambient temperature. In coldweather, the amount of washer fluid used willalso be increased automatically to help improvecleaning.
Heated washer nozzles
*The washer nozzles are heated automatically incold weather to help prevent the washer fluidfrom freezing.
High-pressure headlight washing *High-pressure headlight washing consumes alarge quantity of washer fluid. To save fluid, theheadlights are washed once for every five timesthe windshield is washed.
Reduced washingWhen approx. 1 US quart (1 liter) of washer fluidremains in the reservoir, the headlights will nolonger be washed to conserve fluid. A text message and the
symbol will be dis-
played in the instrument panel to remind the driver to fill the washer fluid reservoir.

Starting and driving The vehicle is equipped with features that sup- plement its basic functions, such as shifting gears with steering wheel paddles * and the fuel-
conserving start/stop function.
The vehicle is equipped with an automatic trans- mission that also makes it possible to shift gearsmanually. Certain functions can also be used when the engine is not running, depending on the ignitionmode being used.

Brakes The brake system is a hydraulic system consist- ing of two separate brake circuits. If a problemshould occur in one of these circuits, it is stillpossible to stop the vehicle with the other brakecircuit.
Brake systemIf one of the brake circuits is not functioning, more pressure will be needed on the brake pedal(and the pedal will go down farther) for normalbraking effect. If the brake pedal must be depressed farther than normal and requires greater foot pressure,the stopping distance will be longer. Pressure on the brake pedal is enhanced by the power braking function. The power brakes only function when the engine is running. If the power brakes are not working, considerably higher pressure will be required on the brakepedal to compensate for the lack of power assis-tance. This can happen for example when towingyour vehicle or if the engine is switched off whenthe vehicle is rolling. The brake pedal feels stifferthan usual. When the Hill Start Assist function is being used, it will take slightly longer for the brake pedal toreturn to its normal position if the vehicle isparked on an incline or uneven surface. When driving in very hilly areas or if the vehicle iscarrying a heavy load, manual gear shifting canbe used for engine braking to augment the brakes.
Hill Descent Control can also be used
on steep downgrades to increase the engine braking effect at low speeds.
Anti-lock Braking System ABS
The ABS system helps to improve vehicle control (stopping and steering) during severe brakingconditions by limiting brake lockup. When ABS is operating, there may be some vibration in the brake pedal, which is normal. The system performs a brief self-diagnostic test when the engine has been started and driverreleases the brake pedal. Another automatic testmay be performed when the vehicle first reachesa speed of approximately 6 mph (10 km/h). Thebrake pedal will pulsate several times and asound may be audible from the ABS controlmodule, which is normal.
Cleaning the brake discsCoatings of dirt and water on the brake discsmay result in delayed brake function. This delay isminimized by cleaning the brake linings. Cleaning the brake pads is advisable in wet weather, prior to long-term parking, and after thevehicle has been washed. Do this by braking gen-tly for a short period while the vehicle is moving.

Before a long distance trip
It is always worthwhile to have your vehicle checked by a trained and qualified Volvo servicetechnician before driving long distances. Yourretailer will also be able to supply you with bulbs,fuses, spark plugs and wiper blades for your usein the event that problems occur.
As a minimum, the following items should be checked before any long trip:
• Check that engine runs smoothly and thatfuel consumption and the oil level are normal.
• Check for fuel, oil, and fluid leakage.
• Check condition of drive belts.
• Check state of the battery's charge.
• Examine tires carefully (including the sparetire where applicable), and replace those thatare worn. Also, check tire inflation pressure.
• The brakes, front wheel alignment, and steer-ing gear should be checked by a trained andqualified Volvo service technician 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

STARTING AND DRIVING

• Consider your destination. If you will be driv-ing through an area where snow or ice arelikely to occur, consider using snow tires.
Driving economically
Better driving economy can be obtained by thinking ahead, avoiding rapid starts and stopsand adjusting the speed of your vehicle to imme-diate traffic conditions.
Economical driving conserves natural resources
Observe the following rules: • Bring the engine to normal operating tem- perature as soon as possible by driving witha light foot on the accelerator pedal for thefirst few minutes of operation. A cold engineuses more fuel and is subject to increasedwear.
• Whenever possible, avoid using the vehiclefor driving short distances. This does notallow the engine to reach normal operatingtemperature.
• Drive carefully and avoid rapid accelerationand hard braking.
• Use the transmission's Drive (
D) position as
often as possible and avoid using kick-down.
• Using the engine's Eco function can helpimprove fuel economy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extra load)in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when the tires are cold). •
Use tires recommended by Volvo for yourvehicle.
• Remove snow tires when threat of snow orice has ended.
• Note that roof racks, ski racks, etc, increaseair resistance and also fuel consumption.
• At highway driving speeds, fuel consumptionwill be lower with the air conditioning on andthe windows closed than with the air condi-tioning off and the windows open.
• Using the onboard trip computer's fuel con-sumption modes can help you learn how todrive more economically.
Other factors that decrease gas mileage are:
• Dirty air cleaner
• Dirty engine oil and clogged oil filter
• Dragging brakes
• Incorrect front end alignment
Some of the above mentioned items and othersare checked at the standard maintenance inter-vals.
Handling and roadholding
• Vehicle load, tire design and inflation pres-sure all affect vehicle handling. Therefore,check that the tires are inflated to the rec-ommended pressure according to the vehicleload. Loads should be distributed so that

Driving with a trailer
When towing a trailer, always observe the legal requirements of the state/province.
• All Volvo models are equipped with energy- absorbing shock-mounted bumpers. Trailerhitch installation should not interfere with theproper operation of this bumper system.
Trailer towing does not normally present any par-ticular problems, but take into consideration:
• Increase tire pressure to recommended fullpressure.
• When your vehicle is new, avoid towing heavytrailers during the first 620 miles (1,000 km).
• Maximum speed when towing a trailer:50 mph (80 km/h).
• Engine and transmission are subject toincreased loads. Therefore, engine coolanttemperature should be closely watched whendriving in hot climates or hilly terrain. Use alower gear and turn off the air conditioner ifthe temperature gauge needle enters the redrange.
• If the automatic transmission begins to over-heat, a message will be displayed in the textwindow.
• Avoid overload and other abusive operation.
• Hauling a trailer affects handling, durability,and economy. •
It is necessary to balance trailer brakes withthe towing vehicle brakes to provide a safestop (check and observe state/local regula-tions).
• Do not connect the trailer's brake systemdirectly to the vehicle's brake system.
• More frequent vehicle maintenance isrequired.
• Remove the ball holder when the hitch is notbeing used.
NOTE
•
When parking the vehicle with a trailer on a hill, apply the parking brake before put- ting the gear selector in
P. Always follow
the trailer manufacturer's recommenda- tions for wheel chocking.
• When starting on a hill, put the gear selector in
D before releasing the parking
brake.
• If you use the manual (Geartronic) shift positions while towing a trailer, make surethe gear you select does not put toomuch strain on the engine (using toohigh a gear).
• The drawbar assembly/trailer hitch maybe rated for trailers heavier than the vehi-cle is designed to tow. Please adhere toVolvo's recommended trailer weights.
• Avoid driving with a trailer on inclines ofmore than 15%.
