Volvo and the environment
Volvo is committed to the well being of its customers. As a natural part of this commit-ment, we care about the environment inwhich we all live. Caring for the environmentmeans an everyday involvement in reducingour environmental impact. Volvo's environ-mental activities are based on a holistic view,which means we consider the overall environ-mental impact of a product throughout itscomplete life cycle. In this context, design,production, product use, and recycling are allimportant considerations. In production,Volvo has partly or completely phased outseveral chemicals including CFCs, lead chro-mates, asbestos, and cadmium; and reducedthe number of chemicals used in ourplants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic con-verter with a Lambda sond, now called theheated oxygen sensor, in 1976. The currentversion of this highly efficient system reducesemissions of harmful substances (CO, HC,NOx) from the exhaust pipe by approximately95 – 99% and the search to eliminate theremaining emissions continues. Volvo is theonly automobile manufacturer to offer CFC-free retrofit kits for the air conditioning systemof all models as far back as the 1975model 240. Advanced electronic engine con-trols and cleaner fuels are bringing us closerto our goal. In addition to continuous environ-mental refinement of conventional gasoline-powered internal combustion engines, Volvois actively looking at advanced technologyalternative-fuel vehicles. When you drive a Volvo, you become our partner in the work to lessen the car's impacton the environment. To reduce your vehicle'senvironmental impact, you can: •
Maintain proper air pressure in your tires. Tests have shown decreased fuel econ-omy with improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• Drive at a constant speed whenever pos-sible.
• See a trained and qualified Volvo servicetechnician as soon as possible forinspection if the check engine (malfunc-tion indicator) light illuminates, or stayson after the vehicle has started.
• Properly dispose of any vehicle-relatedwaste such as used motor oil, used bat-teries, brake pads, etc.
• When cleaning your vehicle, please usegenuine Volvo car care products. AllVolvo car care products are formulated tobe environmentally friendly.

Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount of condensation thatforms on the windows. Use a commercialwindow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Cabin air filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer toyour Warranty and Service Records Informa-tion booklet, or consult a trained and qualifiedVolvo service technician for these intervals.The filter should be replaced more often whendriving under dirty and dusty conditions. Thefilter cannot be cleaned and therefore shouldalways be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and passenger compartment temperature sensorin the ECC control panel should not be cov-ered in any way as this could cause incorrectinformation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in warm weather, opening the windows andmoonroof* for several minutes before drivingwill help release the warm air from the pas-senger compartment. When the engine is run-ning, close the windows and moonroof anduse the recirculation function for severalminutes to enable the air conditioning to coolthe compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win- dows and optional moonroof are closed. Ifyou drive with the moonroof open, we recom-mend that you manually adjust the tempera-ture and blower control (the LED in the AUTO
switch should be off).
Acceleration
The air conditioning is momentarily disen- gaged during full-throttle acceleration.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climatesystem. Work of this type should only bedone by a trained and qualified Volvo servicetechnician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your vehicle containsa CFC-free refrigerant – R134a (HFC134a).This substance will not deplete the ozonelayer. The approximate amount of R134acontained in the system is a follows: 6-cylinder engine Single A/C system: 1.5 lbs (700 g) Dual 1
A/C system: 2.2 lbs (1000 g)
The system also uses PAG oil.

contaminated outside air, the air intake closes and the air inside the passenger compart-ment is recirculated, i.e. no outside air entersthe vehicle. The filter also cleans recirculatedpassenger compartment air. When the ECC system is in the
AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation function (air in the passenger compartmentrecirculates – no fresh air enters the compart-ment). The LED in the switch will light up toindicate that the function is engaged. • Use this function if the outside air is con- taminated with exhaust gases, smoke,etc or to heat/cool the vehicle quickly.
• Recirculation should not be used for morethan 15 minutes. If your windows begin tofog or mist, make sure that the recircula-tion function is switched off.
• Selecting
Defroster automatically
switches recirculation off.
• Timer mode activation: (Vehicles equip-ped with the Interior Air Quality systemhave no timer mode) Press and hold therecirculation button for at least 3 secondsto activate a recirculation timer mode.The amber LED in the recirculation buttonwill flash 5 times to show that the timermode is being activated. In timer mode, each time the recirculation button ispressed, the climate control system willrecirculate the air in the passenger com-partment for 5 – 12 minutes, dependingon the outside air temperature, and thenrevert back to fresh air.
• Timer mode deactivation: Press and holdthe recirculation button for 3 seconds.The amber LED in the recirculation buttonwill illuminate steadily for 5 seconds toshow a return to "normal" mode.
• In normal mode, when the recirculationbutton is pressed, the climate controlsystem will recirculate the air in the pas-senger compartment until the recircula-tion button is pressed again.
• Timer mode memory: If the vehicle isturned off while timer mode is active,timer mode will still be active when thevehicle is restarted.
AUTO
This function automatically regulates the Electronic Climate Control system so that theselected temperatures are maintained. Theblower, heating, air distribution (air flow), airconditioning, and optional air quality sensorare controlled.

Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid starts andstops and adjusting the speed of your vehicleto immediate traffic conditions. Observe thefollowing 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
D (Drive) position
as often as possible and avoid using"kickdown" to help improve fuel econ-omy.
• Do not exceed posted speed limits.
• Avoid carrying unnecessary items (extraload) in the vehicle.
• Maintain correct tire pressure. Check tirepressure regularly (when tires are cold).
• Remove snow tires when threat of snowor ice has ended. •
Note that roof racks, ski racks, etc,increase air resistance and also fuel con-sumption.
• At highway driving speeds, fuel consump-tion will be lower with the air conditioningon and the windows closed than with theair conditioning off and the windowsopen.
• Using the onboard trip computer's fuelconsumption modes can help you learnhow to drive 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 oth- ers are checked at the standard MaintenanceService intervals.
CAUTION
Drive slowly and carefully if going through standing water (i.e. flooded roadways,etc.). Damage to the engine could result ifexcess water is drawn in through the airintake system. Never drive the vehicle inwater deeper than 18 inches (48 cm).

Belt check
Check the belt regularly to make sure it is in good condition and is clean. A worn or dirtybelt can cause poor cooling and low alterna-tor output as well as impair the operation ofthe power steering and the air conditioningunit.
NOTE
The drive belt is equipped with a self-ten- sioning mechanism and requires noadjustment between changes.
WARNING
The engine must not be running when this check is performed.
Check coolant level
The cooling system must be filled with cool- ant and not leak to operate at maximum effi-ciency. Check the coolant level regularly. Thelevel should be between the MAX and MIN
marks on the expansion tank. The checkshould be made with particular thoroughnesswhen the engine is new or when the coolingsystem has been drained. Do not remove the filler cap other than for topping up with coolant. Frequent removalmay prevent coolant circulation between the engine and the expansion tank during enginewarm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be drained, con-sult a trained and qualified Volvo servicetechnician. Do not top off with water only. This reduces the rust-protective and antifreeze qualities ofthe coolant and has a lower boiling point. Itcan also cause damage to the cooling systemif it should freeze. Top off with Volvo GenuineCoolant/Antifreeze only (a 50/50 mix of waterand antifreeze.
CAUTION
The cooling system must always be kept filled to the correct level. If it is not keptfilled, there can be high local temperaturesin the engine which could result in dam-age. Different types of antifreeze/coolantmay not be mixed.
WARNING
•
Never remove the expansion tank cap while the engine is warm. Wait until theengine cools.
• If it is necessary to top off the coolantwhen the engine is warm, unscrew theexpansion tank cap slowly so that theoverpressure dissipates.
