7 Introduction
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 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 CFCs, lead chromates, asbestos, and cadmium; and reduced the number 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 95-99% 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 and cleaner
fuels are bringing us closer to our goal. After Volvo vehicles 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 vehicle, which makes
the vehicle among the most recycled industrial products. In order to have efficient and well-controlled recycling,
dismantling information is available for all Volvo models. For Volvo, all homogeneous plastic parts weighing more
than 3.4 oz. (100 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.

The defroster function should be used to remove fog or mist from the inside of the windows. Keeping the windows
clean with a commercially available window washing spray will also help prevent fogging or misting.
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 vehicle 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.
Display
The display above the climate control panel shows the climate settings that have been made.
Personal settings
There are two functions in the climate system that can be set to your preferences:
Blower speed to Auto mode (models with ECC only).
Timer controlled recirculation of the air in the passenger compartment.
For information about how to make these settings, see the Personal settings section on page 78
.

General information
Models equipped with ECC (option)
Sensors
The sunlight sensor is on the upper side of the dashboard
The passenger compartment temperature sensor is located behind the climate system control panel.
The ambient temperature sensor is in the driver's side door mirror.
The humidity sensor is in the rearview mirror.
These sensors should never be obstructed.

Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the vehicle for driving short distances. This does not allow the engine to reach
normal operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Use the transmission's (D)rive position as often as possible and avoid using kickdown.
Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the vehicle.
Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
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.
WARNING
Driving with the rear liftgate open : Driving with the rear liftgate open could lead to poisonous exhaust gases
entering the passenger compartment. If the rear liftgate must be kept open for any reason, proceed as follows:
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.
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.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
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.
Driving through water

The vehicle can be driven through water up to a depth of approximately 9 in. (25 cm), at a maximum speed of 6 mph
(10 km/h).
Take particular care when driving through flowing water.
Clean the electrical connections for trailer wiring after driving in mud or water.
When driving through water, maintain low speed and do not stop in the water.
WARNING
After driving through water, press lightly on the brake pedal to ensure that the brakes are functioning normally.
Water or mud can make the brake linings slippery, resulting in delayed braking effect.
CAUTION
Engine damage will occur if water is drawn into the air cleaner.
If the vehicle is driven through water deeper than 9 in (25 cm), water may enter the differential and the
transmission. This reduces the oil's lubricating capacity and may shorten the service life of these components.
Do not allow the vehicle to stand in water up to the door sills longer than absolutely necessary. This could result
in electrical malfunctions.
If the engine has been stopped while the vehicle is in water, do not attempt to restart the engine. Have the vehicle
towed out of the water.
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. Your Volvo retailer stocks plenty
of Volvo engine coolant to help protect your vehicle during cold weather.
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
well as decreasing fuel consumption while the engine is warming up. For winter use, 5W -30 oil, particularly the
synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-weather oil for hard driving or in
warm weather. See page 251
for more information.
The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc. are used more
often. Moreover, the capacity of the battery decreases as the temperature drops. In very cold weather, a poorly charged
battery can freeze and be damaged. It is therefore advisable to check the state of charge
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please
consult a trained and qualified Volvo service technician.

more frequently and spray an anti-rust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires."
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 202 for the
location of the washer fluid reservoir). This is important since dirt is often splashed on the windshield during winter

When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be suspended off the floor or placed on their sides
on the floor. Tires not mounted on rims should be stored on their sides or standing upright, but should not be
suspended.
WARNING
Tires should preferably be stored in a cool, dry, dark place, and should never be stored in close proximity to
solvents, gasoline, oils, etc.
WARNING
The wheel and tire sizes for your Volvo are specified to meet stringent stability and handling requirements.
Unapproved wheel/tire size combinations can negatively affect your vehicle's stability and handling. Approved tire
sizes are shown in the Tire inflation pressure tables on page 170
.
Any damage caused by installation of unapproved wheel/tire size combinations will not be covered by your new
vehicle warranty. Volvo assumes no responsibility for death, injury, or expenses that may result from such
installations.
Tread wear indicator
The tires have wear indicator strips running across or parallel to the tread. The letters TWI are printed on the side of
the tire. When approximately 1/16" (1.6 mm) is left on the tread, these strips become visible and indicate that the tire
should be replaced. Tires with less than 1/16" (1.6 mm) tread offer very poor traction.
When replacing worn tires, it is recommended that the tire be identical in type (radial) and size as the one being
replaced. Using a tire of the same make (manufacturer) will prevent alteration of the driving characteristics of the
vehicle.

Washing the car
The following points should be kept in mind when washing and cleaning the car:
The vehicle should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may
cause damage. To help prevent corrosion, it is particularly important to wash the vehicle frequently in the wintertime
when salt has been used on the roads.
Avoid washing your vehicle in direct sunlight. Doing so may cause detergents and wax to dry out and become
abrasive. To avoid scratching, use lukewarm water to soften the dirt before you wash with a soft sponge, and plenty of
sudsy water.
Bird droppings : Remove from paintwork as soon as possible. Otherwise the finish may be permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the vehicle with a clean chamois and remember to clean the drain holes in the doors and rocker panels.
Tar spots can be removed with kerosene or tar remover after the vehicle has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning of the
windshield and wiper blades improves visibility considerably and also helps prolong the service life of the wiper
blades.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.

Synthetic oil is not used when the oil is changed at the normal service intervals. This oil is only used at customer
request, at additional charge. Please consult a trained and qualified Volvo service technician.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 104° F (40° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and complying with oil quality requirements are recommended for driving
in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
