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 re\
ducing our environmental impact. Volvo's environmental
activities are based on a holistic view, which means we consider the ove\
rall environmental impact of a product throughout its complete
life cycle. In this context, design, production, product use, and recycl\
ing are all important considerations. In production, Volvo has partly
or completely phased out several chemicals including CFCs, lead chromate\
s, 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-wa\
y catalytic converter with a Lambda sond, now called the heated
oxygen sensor, in 1976. The current version of this highly efficient sys\
tem 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 sy\
stem of all models as far back as the 1975 model 240. Advanced
electronic engine controls and cleaner fuels are bringing us closer to o\
ur goal. After Volvo vehicles and parts have fulfilled their use,
recycling is the next critical step in completing the life cycle. The me\
tal content is about 75% of the total weight of a vehicle, which makes
the vehicle among the most recycled industrial products. In order to hav\
e efficient and well controlled recycling, all Volvo variants have
printed dismantling manuals, indicating the weight and material of indiv\
idual components. For Volvo, all homogeneous plastic parts
weighing more than 3.4 oz. (100 grams) are marked with international s\
ymbols that indicate how the component is to be sorted for
recycling. In addition to continuous environmental refinement of convent\
ional 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:
l Maintain proper air pressure in your tires. Tests have shown decreased f\
uel economy with improperly inflated tires.
l Follow the recommended maintenance schedule in your Warranty and Service\
Records Information booklet.
l Drive at a constant speed whenever possible.
l See a trained and qualified Volvo service technician as soon as possible\
for inspection if the check engine (malfunction indicator) light
illuminates, or stays on after the vehicle has started.
l Properly dispose of any vehicle-related waste such as used motor oil, us\
ed batteries, brake pads, etc.
l When cleaning your vehicle, please use genuine Volvo car care products. \
All Volvo car care products are formulated to be
environmentally friendly.

General information
Air conditioning - A/C
Your car is equipped with an Electronic Climate Control (ECC).
The air conditioning system can be switched off, but for optimal air qua\
lity in the passenger compartment
and to prevent the windows from fogging, the air conditioning should be \
left on - even in cool weather.
NOTE

In warm weather, a small amount of water may accumulate under the car wh\
en 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 repai\
rs on the climate system. Work of
this type should only be done by a trained and qualified Volvo service t\
echnician.
Refrigerant
Volvo cares about the environment. The air conditioning system in your c\
ar contains a CFC-free
refrigerant - R134a. This substance will not deplete the ozone layer. Th\
e 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 your Volvo retailer \
for these intervals. The filter
should be replaced more often when driving under dirty and dusty conditi\
ons. 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 t\
hat have been made.
Personal settings
There are two functions in the climate system that can be set to your pr\
eferences:
l Blower speed to Auto mode (models with ECC only).
l Timer controlled recirculation of the air in the passenger compartment.

122 06 Starting and driving
General information
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid\
starts and stops and adjusting
the speed of your vehicle to immediate traffic conditions.
Observe the following rules:
l 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.
l Whenever possible, avoid using the vehicle for driving short distances. \
This does not allow the engine
to reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Use the transmission's Drive (D) position as often as possible and avo\
id using kickdown.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the vehicle.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l At highway driving speeds, fuel consumption will be lower with the air c\
onditioning on and the
windows closed than with the air conditioning off and the windows open. \
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard\
maintenance intervals.
Avoid overheating the engine
Do not drive at engine speeds above 4,500 rpm if you tow a trailer in hi\
lly areas. This could cause the
engine oil to overheat.
