Volvo and the environment
Volvo is committed to the well being of its customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact. Volvo's environmental activities are based on a holistic view, which means we consider the
overall environmental impact of a product
pg. 3 Introduction
throughout its complete life cycle. In this context, design, production, product use, and recycling are all important
considerations. In production, Volvo has partly or completely phased out several chemicals including freons, lead
chromates, naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50%
since 1991.
Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda sond, now
called the heated oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system of all models as far back as the 1975 model 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal. After Volvo cars and parts have fulfilled their
use, recycling is the next critical step in completing the life cycle. The metal content is about 75% of the total weight
of a car, which makes the car among the most recycled industrial products. In order to have efficient and well
controlled recycling, many Volvo variants have printed dismantling manuals, indicating the weight and material of
individual components. For Volvo, all homogeneous plastic parts weighing more than 1.7 oz. (50 grams) are marked
with international symbols that indicate how the component is to be sorted for recycling. In addition to continuous
environmental refinement of conventional gasoline-powered internal combustion engines, Volvo is actively looking at
advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment. To reduce
your vehicle's environmental impact, you can:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated tires.
Follow the recommended maintenance schedule in your Warranty and Service Records Information booklet.
Drive at a constant speed whenever possible.
See a trained and qualified Volvo service technician as soon as possible for inspection if the check engine
(malfunction indicator) lamp illuminates, or stays on after the vehicle has started.
Properly dispose of any vehicle-related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to the
environment.

pg. 58 Climate
General information
Air conditioning - A/C
Your car is equipped with Electronic Climate Control (ECC), which automatically maintains the selected temperature
in the passenger compartment and helps dehumidify the air.
NOTE:
The air conditioning system can be switched off, but for optimal air quality in the passenger compartment and to
prevent the windows from fogging, the air conditioning should be left on - even in cool weather.
In warm weather, a small amount of water may accumulate under the car when it has been parked. This water is
condensation from the A/C system and is normal.
Ice and snow
Always keep the air intake grille at the base of the windshield free of snow.
Climate control maintenance
Special tools and equipment are required to maintain and carry out repairs on the climate system. Work of this type
should only be done by a trained and qualified Volvo service technician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your car contains a CFC-free refrigerant - R134a.
This substance will not deplete the ozone layer. The system contains 1.2 lbs (530 g) R134a (HFC 134a), and uses PAG
oil.
Passenger compartment filter
Replace the cabin air filter with a new one at the recommended intervals. Please refer to your Warranty and Service
Records Information booklet, or consult a trained and qualified Volvo service technician for these intervals. The filter
should be replaced more often when driving under dirty and dusty conditions. The filter cannot be cleaned and
therefore should always be replaced with a new one.
NOTE: There are different types of cabin air filters. Ensure that the correct type is installed.

ECC functions
1. Auto -On/Off
The AUTO function automatically regulates climate control to maintain the desired temperature. The
automatic function controls heating, air conditioning, blower speed, recirculation, and air distribution.
When the retractable hard top is down, warm or cool air from the climate system is directed downward in the
passenger compartment, and the climate system's effect is limited if it is not possible to compensate for the ambient
temperature.
If you select one or more manual functions, the remaining functions continue to be controlled automatically. All
manual settings are switched off when AUTO is switched on. AUTO CLIMATE is shown in the display.
2. Blower speed
The blower speed can be increased or decreased by turning the knob. The blower speed is regulated
automatically if AUTO is selected. The previously set blower speed is disconnected.
NOTE: If the knob is turned counterclockwise and the blower indication in the display goes out, the blower and the air
conditioning are switched off. The display shows the blower symbol and OFF.
3. Recirculation
This function can be used to shut out exhaust fumes, smoke, etc from the passenger compartment. The air
in the passenger compartment is then recirculated, i.e. no air from outside the car is taken into the car when this
function is activated.
ProCarManuals.com
pg. 61 Climate
Electronic climate control (ECC)
If the air in the car recirculates for too long, there is a risk of condensation forming on the insides of the windows,
especially in winter.
Timer
The timer function minimizes the risk of fogging, or stale air when the recirculation function is selected. See page 52
for information on setting the recirculation timer.
NOTE: Recirculation is always disengaged if the defroster button is engaged to clear ice or condensation from the side
windows.
4. Defroster
Directs airflow to the windshield and side windows and increases blower speed. The LED in the defroster
button lights up when this function is activated. The air conditioning system is controlled to provide maximum air
dehumidification. The air is not recirculated.
5. Airflow controls
Press one of the three buttons in the illustration to activate the selected airflow. A symbol in the display
above the climate control panel and a lit LED in the selected button indicate that the manual function has been
selected. With manually selected airflow both warm and cool air can be selected. See also the table on page 63
.
6. Air conditioning On/Off
The air conditioning system is controlled automatically by the system when the ON LED is lit to maintain
the selected temperature.
When OFF is selected and the OFF LED is lit, the air conditioning system is deactivated. Other functions are still
controlled automatically.
When Defroster (4) is selected, the air conditioning system is activated for maximum dehumidifying.
7 and 8. Heated front seats (option)
Maximum heating: Press the button once - both LEDs light up.
Reduced heating: Press the button a second time - one LED lights up.
Seat heating off: Press the button a third time - no LEDs are lit.
9. Rear window and door mirror defrosters
Press to defrost the rear window and door mirrors.

At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how 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 others are checked at the standard maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
WARNING!
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason,
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
pg. 99 Starting and driving
General information
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to -31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze
is not approved by Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator.
Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as
ProCarManuals.com
Never attempt to push- or tow-start a vehicle with a dead battery. This would inject unburned fuel into the three-
way catalytic converter(s), causing overheating, backfiring, and damage. See page 119 for instructions on jump
starting the vehicle.
Having the car towed
Volvo recommends the use of flat bed equipment for towing vehicles with front wheel drive. If wheel lift equipment
must be used, please use extreme caution to help avoid damage to the vehicle.
In this case, the vehicle should be towed with the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the previous page.
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use slingtype equipment at the rear or apply lifting equipment inside the rear wheels;
serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the flat
bed. Consult the tow truck operator.
WARNING!
The towing eyelets must not be used for pulling the vehicle out of a ditch or for any similar purpose involving
severe strain.
Do not use the towing eyelets to pull the vehicle up onto a flat bed tow truck.
pg. 119 Starting and driving
Jump starting
Follow these instructions to jump start your vehicle's dead battery or to jump start another vehicle's dead battery using
your vehicle. If the 12-volt auxiliary battery to be used is in another vehicle, check that the vehicles are not touching to
prevent premature completion of a circuit. Be sure to follow jump starting instructions provided for the other vehicle.
To jump start your vehicle:
Switch off the ignition.
First connect the auxiliary battery positive (+) terminal (1) to the positive (+) terminal in your vehicle's battery (2),
marked with a "+" sign.
Connect the auxiliary battery's negative (-) terminal (3) to the ground point in your vehicle's engine compartment
near the driver's side spring strut (4).
Start the engine in the assisting vehicle, then start the engine in the vehicle with dead battery.

Clean with soapy water or a detergent. For more difficult spots caused by oil, ice cream, shoe polish, grease, etc.,
use a clothing/fabric stain remover. Consult your Volvo retailer.
Interior plastic components
Cleaning interior plastic components should be done with a cleaning agent specially designed for this purpose.
Consult your Volvo retailer.
Alcantera™ suede-like material
Suede -like upholstery can be cleaned with a soft cloth and mild soap solution.
Leather care
Volvo's leather upholstery is manufactured with a protectant to repel soiling. Over time, sunlight, grease and dirt can
break down the protection. Staining, cracking, scuffing, and fading can result.
Volvo offers an easy-to-use, non-greasy leather care kit formulated to clean and beautify your vehicle's leather, and to
renew the protective qualities of its finish. The cleaner removes dirt and oil buildup. The light cream protectant
restores a barrier against soil and sunlight.
Volvo also offers a special leather softener that should be applied after the cleaner and protectant. It leaves leather soft
and smooth, and reduces friction between leather and other finishes in the vehicle.
Volvo recommends cleaning, protecting and conditioning your vehicle's leather two to four times a year. Ask your
Volvo retailer about Leather Care Kit 951 0251 and Leather Softener 943 7429.
CAUTION!
Under no circumstances should gasoline, naphtha or similar cleaning agents be used on the plastic or the leather
since these can cause damage.
Take extra care when removing stains such as ink or lipstick since the coloring can spread.
Use solvents sparingly. Too much solvent can damage the seat padding.
Start from the outside of the stain and work toward the center.
Sharp objects (e.g. pencils or pens in a pocket) or Velcro fasteners on clothing may damage the textile upholstery.
Cleaning the seat belts
Clean only with lukewarm water and a mild soap solution.
Cleaning floor mats
The floor mats should be vacuumed or brushed clean regularly, especially during winter when they should be taken out
for drying. Spots on textile mats can be removed with a mild detergent. For best protection in winter, Volvo
recommends the use of Volvo rubber floor mats. Consult your Volvo retailer.
pg. 151 Vehicle care
Paint touch up
Touching up minor paint damage
Paint damage requires immediate attention to avoid rusting. Make it a habit to check the finish regularly - when
washing the vehicle for instance. Touch-up if necessary. Paint repairs require special equipment and skill. Contact your
Volvo retailer for any extensive damage. Minor scratches can be repaired by using Volvo touch-up paint.
