Introduction

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.

Fuel requirements

Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
store-bought fuel injector cleaning addi-
tives.
Unleaded fuel
Each Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense leaded fuel into a vehicle labelled
"unleaded gasoline only". Leaded gasoline
damages the three-way catalytic converter and
the heated oxygen sensor system. Repeated
use of leaded gasoline will lessen the effective-ness of the emission control system and could
result in loss of emission warranty coverage.
State and local vehicle inspection programs
will make detection of misfueling easier, pos-
sibly resulting in emission test failure for mis-
fueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain
an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician for maintenance.
Gasoline containing alcohol and ethers
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws
require that the service pump be marked indi-
cating use of alcohols or ethers. However,
there are areas in which the pumps are
unmarked. If you are not sure whether there is
alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel. Volvo allows theuse of the following "oxygenated" fuels; how-
ever, the octane ratings listed on this page
must still be met.
Alcohol – Ethanol: Fuels containing up to 10%
ethanol by volume may be used. Ethanol may
also be referred to as Ethyl alcohol, or "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.
Fuel filler door
Press the button on the light switch panel (see
the illustration on page 64) with the ignition
switched off to unlock the fuel filler door.
Please note that the fuel filler door will remain
unlocked until the vehicle begins to move for-
ward. An audible click will be heard when the
fuel filler door relocks.
If you intend to leave your vehicle while it is
being refueled, this feature enables you to lock
the doors/trunk while leaving the fuel filler door
unlocked.

160
WARNING
Towing a vehicle with a locked steering
wheel will make the vehicle impossible to
steer.
2. Insert the key into the ignition to unlock the
steering wheel. The steering wheel must be
unlocked. With the engine off and the vehi-
cle at a standstill, great effort will be
required to turn the steering wheel.
3.
Turn the ignition key to position II.
4. Place the gear selector in neutral. For vehi-
cles with automatic transmissions, follow
instruction on page 152, "Shiftlock over-
ride" to allow the gear selector to be moved
from the Park position.
5. Keep firm pressure on the brake pedal
while releasing the parking brake.
6. When towing has been completed, return
the gear selector to Park and apply the
parking brake.
The following points should also be
observed:
•Never exceed 50 mph (80 km/h). Never
exceed local towing speed limits and heed
all local towing restrictions.
•Never tow farther than 50 miles (80 km).
•Keep the tow rope taut at all times while the
vehicle is in motion.
•The disabled vehicle should be towed in
the forward direction only.
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 162 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.

279 Three-way catalytic converter –
general information
•Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.
•Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot exhaust
system and cause such materials to ignite
under certain wind and weather condi-
tions.
•Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•Remember that tampering or unauthorized
modifications to the engine, the Electronic
Control Module, or the vehicle may be ille-
gal and can cause three-way catalytic con-
verter or exhaust system overheating. This
includes: altering fuel injection settings or
components, altering emission systemcomponents or location, or removing com-
ponents, and/the repeated use of leaded
fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.
