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.

steering wheel). Within this context, they
should strive to position the seat with as large
a distance as possible between their belly and
the steering wheel.
Child seats
Please refer to page 40 for information on
securing child seats with the seat belts.
Seat belt reminder
G029652
Seat belt reminder light in ceiling console
The seat belt reminder consists of an audible
signal, an indicator light near the rearview mir-
ror and a symbol in the instrument panel that
alert all occupants of the vehicle to fasten theirseat belts. The audible signal and warning light
will be on for a total of 6 seconds from the time
the ignition is switched on, regardless of
whether or not the seat belts are fastened.
If the front seat belts are unbuckled while the
vehicle is in motion, the audible signal and
warning light will be active for a total of 6 sec-
onds.
Rear seatsThe seat belt reminder in the rear seat has two
additional functions:
•It provides information about which seat
belts are fastened in the rear seat. A mes-
sage will appear in the information display
when a belt is being used. This message
will disappear after approximately 6 sec-
onds or can be erased by pressing the
READ button on the left steering wheel
lever.
•It also provides a reminder if one of the
occupants of the rear seat has unbuckled
his/her seat belt while the vehicle is in
motion. A visual and audible signal will be
given. These signals will stop when the
seat belt has been re-buckled or can be
stopped by pressing the READ button.
The message in the information display can
always be accessed, even if it has been erased,
by pressing the READ button to display stored
messages.
Seat belt maintenance
Check periodically that the seat belts are in
good condition. Use water and a mild deter-
gent for cleaning. Check seat belt mechanism
function as follows: attach the seat belt and pull
rapidly on the strap.

01 Safety
Occupant Weight Sensor (OWS)01

29
WARNING
If a fault in the system is detected and indi-
cated as explained on the preceding page,
be aware that the passenger's side front air-
bag will not deploy in the event of a collision.
In this case, the SRS system and Occupant
Weight Sensor should be inspected by a
trained and qualified Volvo service techni-
cian as soon as possible.
WARNING
•Never try to open, remove, or repair any
components in the OWS system. This
could result in system malfunction.
Maintenance or repairs should only be
carried out by an a trained and qualified
Volvo service technician.
•The front passenger's seat should not
be modified in any way. This could
reduce pressure on the seat cushion,
which might interfere with the OWS sys-
tem's function.
The OWS is designed to disable (will not inflate)
the passenger's side front airbag when a rear
facing infant seat, a forward-facing child
restraint, or a booster seat is detected. The
PASSENGER AIRBAG OFF indicator lamp will
illuminate and stay on to remind you that thepassenger's side front airbag is disabled (see
the following table).

AVolvo recommends that children always be properly
restrained in appropriate child restraints in the rear seats. Do
not assume that the passenger's side front airbag is disabled
unless the PASSENGER AIRBAG OFF indicator lamp is lit.
Make sure the child restraint is properly installed. If there is
any doubt as to the status of the passenger's side front air-
bag, move the child restraint to the rear seat.
The OWS is designed to enable (may inflate)
the passenger's side front airbag in the event
of a collision anytime the system senses that aperson of adult size is sitting properly in the
front passenger's seat. The PASSENGER
AIRBAG OFF indicator lamp will be off and
remain off.
If a person of adult size is sitting in the front
passenger's seat, but the PASSENGER
AIRBAG OFF indicator lamp is on, it is possible
that the person isn't sitting properly in the seat.
If this happens:
1. Turn the vehicle off and ask the person to
place the seatback in an upright position.
2. Have the person sit upright in the seat,
centered on the seat cushion, with the per-
son's legs comfortably extended.
3. Restart the vehicle and have the person
remain in this position for about two
minutes. This will allow the system to
detect that person and enable the pas-
senger's frontal airbag.
4.
If the PASSENGER AIRBAG OFF indicator
lamp remains on even after this, the person
should be advised to ride in the rear seat.
This condition reflects limitations of the OWS
classification capability. It does not indicate
OWS malfunction.ModificationsIf you are considering modifying your vehicle in
any way to accommodate a disability, for

01 Safety
Roll-over Protection system (ROPS) 01
36
Introduction
G020797
Deployed ROPS roll bars
The ROPS system consists of two roll bars
located behind the rear seat head restraints,
and a sensor that monitors the roll or pitch
angle of the vehicle.
If the vehicle rolls or pitches beyond a preset
angle, or in the event of a rear-end collision of
sufficient force, the roll bars are automatically
deployed (raised).
The ROPS system is designed to function
regardless of whether the power retractable
hard top is up or down. By design, the tops of
the roll bars are equipped with a point in order
to pierce the rear window if the top is up.
NOTE
If ROPS has deployed, the system should
be inspected by a trained and qualified
Volvo service technician.
WARNING
•The rear seat of the Volvo C70 is
intended for two occupants, and only
two rear seat belts are provided. The
center section of the seat should never
be used to seat a passenger.
•No objects should be placed over the
roll bars or behind the rear seat head
restraints.
•All repairs or maintenance to the ROPS
system should only be performed by a
trained and qualified Volvo service tech-
nician.

to indicate a fault that could affect
the car's drivability.This symbol
illuminates when the vehicle is
traveling at speeds above 5 mph
(7 km/h). A text explaining the nature of the fault
will also be shown in the information display.
The symbol and accompanying text will remain
on until the fault has been corrected. This sym-
bol may also light up in combination with other
indicator or warning symbols.
If the red warning symbol lights up:
1. Stop the car as soon as possible in a suit-
able location.
2. Read the message in the information dis-
play.
3. Follow the instructions provided, or con-
tact a trained and qualified Volvo service
technician. Erase the message by pressing

88
Air conditioning – A/C
Your car is equipped with a climate control
system that includes either manually adjusta-
ble air conditioning or optional Electronic Cli-
mate Control (ECC).
The air conditioning system can be switched
off, but for optimal air quality 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 when 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.
Fog on the inside of the windows
The 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
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 tech-
nician.
Refrigerant
Volvo 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 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 Informa-
tion 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.

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.
•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 trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:
1. Close the windows.
2. 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 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 dis-
tributed 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.
