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 par\
tly or completely phased out several
chemicals including freons, lead chromates, naphtanates, asbestos, mercu\
ry 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-wa\
y catalytic converter with a Lambda sond,
now called oxygen sensor, in 1976. The current version of this highly ef\
ficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximatel\
y 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 vehicles and parts have fulfilled their use, recycling is th\
e 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 contro\
lled recycling, many Volvo variants have
printed dismantling manuals, indicating the weight and material of indiv\
idual components. For Volvo, all
homogeneous plastic parts weighing more than 1.7 oz. (50 grams) are ma\
rked with international symbols that
indicate how the component is to be sorted for recycling.
In addition to continuous environmental refinement of conventional gasol\
ine-powered internal combustion
engines, Volvo is actively looking at advanced technology alternative-fu\
el vehicles.
When you drive a Volvo, you become our partner in the work to lessen the\
vehicle'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.
l See an authorized Volvo retailer as soon as possible for inspection if t\
he check engine (malfunction indicator)
lamp 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, use Volvo's own vehicle care products, all o\
f which have systematically been
adapted to the environment.
PremAir® (certain models only)
The surface of the radiator in the engine compartment
1 is treated with a special coating called PremAir2. This
coating works as a catalytic converter, converting most of the ground le\
vel ozone passing through the

reservoir.
NOTE: Press the brake pedal hard and maintain pressure on the pedal - do not \
pump the brakes.
WARNING!
If the fluid level is below the MIN mark in the reservoir or if a "Brake\
failure - Service urgent"
message is displayed in the text window: DO NOT DRIVE. Have the vehicle \
towed to a Volvo
retailer and have the brake system inspected.
NOTE: When the vehicle is at a standstill and the engine is idling, e.g. at a\
traffic light and the brake
pedal is depressed, the pedal may go down slightly. This is a normal fun\
ction of the power-assisted
brake system.
Power brakes function only when the engine is running
The power brakes utilize vacuum pressure which is only created when the \
engine is running. Never let
the vehicle roll to a stop with the engine switched off.
If the power brakes are not working, the brake pedal must be pressed app\
roximately four times harder
than usual to make up for the lack of power assistance. This can happen \
for example when towing your
vehicle or if the engine is switched off when the vehicle is rolling. Th\
e brake pedal feels harder than
usual.
Water on brake discs and brake pads affects braking
Driving in rain and slush or passing through an automatic car wash can c\
ause water to collect on the
brake discs and pads. This will cause a delay in braking effect when the\
pedal is depressed. To avoid
such a delay when the brakes are needed, depress the pedal occasionally \
when driving through rain,
slush etc. This will remove the water from the brakes. Check that brake \
application feels normal. This
should also be done after washing or starting in very damp or cold weath\
er.
Severe strain on the brake system
The brakes will be subject to severe strain when driving in mountains or\
hilly areas or towing. Vehicle
speed is usually slower, which means that the cooling of the brakes is l\
ess efficient than when driving on
level roads. To reduce the strain on the brakes, shift into a lower gear\
and let the engine help with the
braking. Do not forget that, if you are towing a trailer, the brakes wil\
l be subjected to a greater than
normal load.
