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.

Brake lights
The brake lights come on automatically when
the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event
of sudden braking or if the ABS system is acti-
vated. This function causes an additional tail-
light on each side of the vehicle to illuminate to
help alert vehicles traveling behind.
The adaptive brake lights activate if:
•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
Brake pad inspection
On vehicles equipped with a jack*, the condi-
tion of the brake pads can be checked by rais-
ing the vehicle (see page 200 for information
about using the jack and removing a wheel)
and performing a visual inspection of the brake
pads.
WARNING
•If the vehicle has been driven immedi-
ately prior to a brake pad inspection, the
wheel hub, brake components, etc., will
be very hot. Allow time for these com-
ponents to cool before carrying out the
inspection.
•Apply the parking brake and put the
gear selector in the Park (P) position.
•Block the wheels standing on the
ground, use rigid wooden blocks or
large stones.
WARNING
•Use the jack intended for the vehicle
when changing a tire. For any other job,
use stands to support the vehicle.
•The jack should be kept well-greased
and clean, and should not be damaged.
•Be sure the jack is on a firm, level, non-
slippery surface.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.
•The jack must correctly engage the jack
attachment.
•Never allow any part of your body to be
extended under a vehicle supported by
a jack.
Brake circuit malfunction
The brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.

A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in 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 system message is
shown in the information display, DO NOT
DRIVE. Have the vehicle towed to a Volvo
retailer and have the brake system inspec-
ted.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
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 cause 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 occa-
sionally 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 weather.
Severe strain on the brake system
The brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less 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 will be subjected to
a greater than normal load.
Anti-lock brakes (ABS)
The Anti-lock Braking System (ABS) helps to
improve vehicle control (stopping and steering)
during severe braking conditions by limiting
brake lockup. When the system "senses"
impending lockup, braking pressure is auto-
matically modulated in order to help prevent
lockup that could lead to a skid.
The system performs a self-diagnostic test
when the engine is started and when the
vehicle first reaches a speed of approxi-
mately 12 mph (20 km/h). The brake pedal will
pulsate several times and a sound may be
audible from the ABS control module. This is
normal.
For optimal ABS braking effect:1. Press down on the brake pedal with full
force. The pedal will pulsate.
2. Steer the vehicle in the direction of travel
and keep the brake pedal depressed.
Electronic Brake Force Distribution
(EBD)
EBD is an integrated part of the ABS system.
EBD regulates the hydraulic pressure to the
rear brakes to help provide optimal braking
capacity.
The switching of the ABS modulator will be
audible and the brake pedal will pulsate during
