Volvo and the environment
Volvo is committed to the well being of its cus-
tomers. 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 environ-
mental 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 emis-
sions 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 elec-
tronic engine controls and cleaner fuels are
bringing us closer to our goal. In addition tocontinuous environmental refinement of con-
ventional gasoline-powered internal combus-
tion engines, Volvo is actively looking at
advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our part-
ner 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 econ-
omy with improperly inflated tires.
•Follow the recommended maintenance
schedule in your Warranty and Service
Records Information booklet.
•Drive at a constant speed whenever pos-
sible.
•See a trained and qualified Volvo service
technician as soon as possible for inspec-
tion if the check engine (malfunction indi-
cator) light illuminates, or stays on after the
vehicle has started.
•Properly dispose of any vehicle-related
waste such as used motor oil, used batter-
ies, brake pads, etc.
•When cleaning your vehicle, please use
genuine Volvo car care products. All Volvo
car care products are formulated to be
environmentally friendly.
RecyclingAs part of Volvo’s commitment to the environ-
ment, it is essential for the vehicle to be recy-
cled in an environmentally sound way. Almost
the entire vehicle can be recycled and for that
reason, the vehicle’s final owner is requested
to contact a Volvo retailer for information about
approved and certified recycling facilities.

Introduction
Air conditioningThe vehicle is equipped with Electronic Climate
Control (ECC). The climate control system
cools, heats or dehumidifies the air in the pas-
senger compartment.
NOTE
•The air conditioning can be switched
off, but to ensure the best possible cli-
mate comfort in the passenger com-
partment and to prevent the windows
from misting, it should always be on.
•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.
Sensor location
•The sunlight sensor is located on the top
side of the dashboard.
NOTE
The sunlight sensor monitors which side of
the car that is most exposed to sunlight.
This can mean that the temperature may
differ between the right and left-side air
vents, even if the temperatures set for both
sides of the passenger compartment are the
same.
•The temperature sensor for the passenger
compartment is located below the climate
control panel.
•The outside (ambient) temperature sensor
is located on the door mirror.
•The humidity sensor* is located in the inte-
rior rearview mirror.
NOTE
Do not cover or block the sensors with
clothing or other objects.
Side windows and moonroofTo ensure that the air conditioning works opti-
mally, the side windows, and the optional
moonroof should be closed.
Fog on the inside of the windowsThe defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-mercially available window washing spray will
also help prevent fogging or misting.
Temporary shut-off of the air
conditioning
The air conditioning is momentarily disen-
gaged during full-throttle acceleration or when
driving uphill with a trailer. This may result in a
temporary increase in cabin temperature.
Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.
Climate system maintenanceSpecial 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 tech-
nician.
RefrigerantVolvo 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 air condi-
tioning system contains 1.7 lbs (770 g) of
R134a. The systems uses PAG oil.
Passenger compartment filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to

dows.
Temperature controlThe temperatures on the
driver and passenger sides
can be set independently.
When the vehicle is started,
the most recent setting is
resumed.
NOTE
Heating or cooling cannot be speeded up by
selecting a higher/lower temperature than
the actual temperature required.
A/C – ON/OFFThe air conditioning is con-
trolled automatically by the
system when the ON light is
on. This cools/heats and
dehumidifies the incoming air.
When the OFF light is on, the
air conditioning is always dis-
engaged. Other functions are still controlled
automatically. When defroster is selected, the
air conditioning system is set for maximum
blower speed and dehumidification.
DefrosterThis function defrosts/de-ices
the windshield and front side
windows. The indicator light
in the defroster button lights
when the function is active.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
Air conditioning can be switched off by
pressing the AC button.

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:
•Bring the engine to normal operating tem-
perature 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 Drive (D) position
as often as possible and avoid using kick-
down.
•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 con-
sumption.
•At highway driving speeds, fuel consump-
tion 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 tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the tailgate 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 win-
dows and the blower control to its high-
est setting.
Weight distribution affects handlingAt 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, roadholdingVehicle 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 dis-
tributed so that capacity weight or maximum
permissible axle loads are not exceeded.
