Volvo and the environment
Volvo is committed to the well being of our
customers. 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 environmental 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 freons,
lead chromates, naphtanates, asbestos, mercury
and cadmium; and reduced the amount of
chemicals used in our plants 50% since 1991.

In use, Volvo was the first in the world to
introduce into production a three-way catalytic
converter with a Lambda sond, now called
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% 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 for
all models back to the M/Y 1975 240.
Advanced electronic engine controls, refined
purification systems and cleaner fuels are
In addition to continuous environmental
refinement of conventional gasoline-powered
internal combustion engines, Volvo is actively
looking at advanced technology alternative-
fuel vehicles.

When you drive a Volvo, you become our
partner in the work to lessen the car'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 fuel
economy with improperly inflated tires
l Follow the recommended maintenance
schedule
l Drive at a constant speed
l See an authorized Volvo retailer as
soon as possible for inspection if the
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, used
batteries, brake pads, etc.
l When cleaning your car, use Volvo's
own car care products, all of which
have systematically been adapted to the
environment

WARNING!
As its name implies, SRS is designed to be a
SUPPLEMENT to - not a replacement for - the
three-point belt system. For maximum
protection, wear seat belts at all times. Be
aware that no system can prevent all possible
injuries that may occur in an accident.
VOLVO SRS (cont.) pg. 5
A self-diagnostic system incorporated in the sensor
monitors the SRS. This system does not, however,
monitor the SIPS airbags. If a fault is detected, the
"SRS" warning light will illuminate. The light is
included in the warning/indicator light cluster in the
instrument panel. Normally, the SRS warning lamp
should light up when the ignition is switched on
and should go out after 10 seconds or when the
engine is started. Check that this light is
functioning properly every time the car is started.

The following items are monitored by all the self-
diagnostic system:
l Sensor unit
l Cable harness
There is no maintenance to perform on the SRS
yourself. The only periodic maintenance
recommended on the SRS is that the air bag
modules and front seat belts (including tensioners)
should be replaced approximately every ten years
and that the other components in the system
(wiring, connectors, etc.) should also be inspected
at this time. The SRS decal on your car shows the
month and year servicing is due. This service must
be performed by an authorized Volvo retailer.
Should you have any questions about the SRS
system, please contact your authorized Volvo
Retailer or Volvo Customer Support.

The warning lights described on pages 18 and 19 should never stay on whe\
n driving

When the ignition key is turned on, and before the engine starts, all of\
the warning lights should be on
to test the function of the bulbs. Should a light not go off after the e\
ngine has started, the system
indicated should be inspected. However, the parking brake reminder light\
will not go off until the
parking brake is fully released.
Generator warning
light

If the light comes on while the
engine is running, have the
charging system checked.

Malfunction
indicator lamp

If the lamp comes on (or stays
on after the vehicle has started),
the engine diagnostic system
has detected a possible fault in
the emission control system.
Although driveability may not
be affected, see an authorized
Volvo retailer as soon as
possible for inspection.

NOTE:If the fuel filler cap is
not closed tightly or if the
engine is running when the car
is refueled, the Malfunction
Indicator Lamp may indicate a
fault. Use only Volvo original
or approved fuel filler caps.
Oil pressure warning
light

If the light comes on while
driving, stop the car and then s
If the light stays on after restart,
have the car towed to the
nearest authorized Volvo
retailer. After hard driving, the
light may come on occasionally
when the engine is idling. This
is normal, provided it goes off
when the engine speed is
increased.

Parking brake
reminder light

This light will be on when the
parking brake (hand brake) is
applied. The parking brake
lever is situated between the
front seats. Canadian models
are equipped with this warning
light:

Brake failure
warning light

If the light comes on while
driving or braking, stop
immediately, open the hood and
check the brake fluid level in the
reservoir. See page 114 for
reservoir position.
Canadian models are equipped
with this warning light:


WARNING!
If the level is below the MIN
mark in either section of the
reservoir: DO NOT DRIVE.
Tow the car to a Volvo
retailer and have the brake
system checked and any
leakage repaired.

A new car should be broken-in!

Refrain from utilizing your car's full driving
potential, e.g. full-throttle acceleration, during the
first 1,200 miles (2,000 km).

Automatic transmission

Do not use "kick-down" during the first 1,200
miles (2,000 km).

NOTE - ENGINE OIL:

Although some oil consumption during normal
engine operation, more oil is consumed when the
engine is new as the internal parts generate higher
friction while wearing-in to each other. From the
time the engine is new until the first service is
performed, the oil consumption could be
higher than normal. For this reason, it is
especially important to check the oil every time
you refuel your car during this period. See
page 108.
In general, the rate of oil consumption depends on
such factors as: engine temperature, length of trip,
driving conditions, oil viscosity and quality,
engine speed and acceleration/deceleration.
Checking your engine oil level each time the car
is refuelled is one of the most important items
you can perform to help keep your car in good
running order.

Deposit control gasoline (detergent
additives)

Volvo recommends the use of gasoline containing
deposit control additives. These additives have
shown to be efficient in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good
driveability and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station operator.
Unleaded Fuel

Each Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps
delivering unleaded gasoline be labeled
"UNLEADED". Only these pumps have nozzles
which fit your car's filler inlet. It is unlawful to
dispense leaded fuel into a vehicle labeled
"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 effectiveness 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, possibly resulting
in emission test failure for misfueled 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 affected,
and the Malfunction Indicator Lamp located on
your instrument panel may light. If this occurs,
please return your vehicle to an authorized Volvo
retailer for service.

NOTE: Do not add additives yourself to the
gasoline, unless you are recommended to do so
by an authorized Volvo retailer.
Fuel requirements, Refueling pg. 55
Octane Rating

Volvo engines are designed for
optimum performance on
unleaded premium gasoline
with an octane rating, AKI of
91, or above. AKI (ANTI
KNOCK INDEX) is an average
of the Research Octane
Number, RON, and the Motor
Octane Number, MON, (RON
+ MON/ 2).
The minimum octane
requirement is AKI 87 (RON
91).

Gasoline Containing
Alcohol and Ethers

"Oxygenated fuels"
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 indicating use of
alcohol 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
seasonal air quality restrictions,
some states require the use of
"oxygenated" fuel in certain
areas.
Alcohol -- Ethanol
Fuels containing up to 10%
ethanol by volume may be
used.
Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers -- MTBE
Fuels containing up to 15%
MTBE may be used.

Refueling

The fuel tank filler cap is
located behind the door on the
left rear fender. Open cap
slowly during hot weather
conditions.
When filling, position the cap
in the special bracket on the
door.
After filling the tank, install the
cap and turn until a "click" is
heard.
The fuel tank is designed to
hold approximately 21.1 US
gals (80 liters) with sufficient
volume left over to
accommodate possible
expansion of the fuel in hot
weather. The "usable" capacity
is 20.3 US gallons (77 liters).
When the fuel level is low,
such factors as ambient
temperature, the fuel's "vapor
pressure" characteristics, and
terrain can affect the fuel
pumps' ability to supply the
engine with an adequate supply CAUTION:
l Avoid spilling gasoline during
refueling. Gasolines containing
alcohol can cause damage to
painted surfaces, which may not
be covered under the New
Vehicle Limited Warranty.
l Do not use gasoline
containing methanol (methyl
alcohol, wood alcohol). This
practice can result in vehicle
performance deterioration and
can damage critical parts in the
fuel system. Such damage may
not be covered under the New
Vehicle Limited Warranty.
l Allow for fuel expansion by
not overfilling the tank.
Overfilling could also cause
damage to the emission control
systems.

Volvo allows the use of the
following "oxygenated fuels";
however, the octane ratings
listed on this page must still be
met. of fuel. Therefore, it is
advisable to refuel as soon as
possible when the needle nears
the red zone, or when the fuel
warning light comes on.
Driving economy pg. 56
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:

l Bring the engine to normal
operating temperature 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.

l Whenever possible, avoid
using the car for driving short
distances. This does not allow
the engine to reach normal
operating temperature.

l Drive carefully and avoid
rapid acceleration and hard
braking.

l Do not exceed speed limit.

l Avoid carrying unnecessary
items (extra load) in the car.

l Check tire pressure regularly
l Remove snow tires when
threat of snow or ice has ended.

l Note that roof racks, ski
racks, etc., increase air
resistance and thereby fuel
consumption.

l Avoid using automatic
transmission kick-down feature
unless necessary.

l Avoid using the air
conditioning when it is not
required. When engaged, the
air conditioner's compressor
places places an additional load
on the engine. However, please
note that fuel consumption is
lower with the air conditioning
on than it is when driving with
the air conditioning switched
off and the windows down.

Other factors which decrease
gas mileage are:
l Worn or dirty spark plugs
l Incorrect spark plug gap
l Dirty air cleaner
l Dirty engine oil and clogged
oil filter
l Dragging brakes
l Incorrect front end alignment

Some of the above mentioned

(check when tires are cold). items and others are checked at
the standard Maintenance
Service intervals.

NOTE: Since using (D)rive
improves fuel economy, it
should be used as often as
possible.
Starting the engine pg. 57
Starting and stopping a
car equipped with
automatic transmission

1 Fasten the seat belt.
WARNING! Before
starting, check that the seat
is adjusted properly. Make
sure the brake pedal can be
depressed completely. Move
the seat closer if necessary.
Refer to section "Front
seats".

2 Apply the parking brake, if
not already set. The gear
selector is locked in the (P)ark
position (SHIFTLOCK).

3Without touching the
accelerator pedal ,turn the
ignition key to the starting
position. Allow the starter to
operate for 5-10 seconds.
Release the key as soon as the
engine starts. If the engine fails
to start, repeat step 3.

5 Select desired gear. The gear
engages after a slight delay,
especially noticeable when
selecting R.
CAUTION: Engine should
be idling; never accelerate
until after you feel the gear
engage! Too rapid
acceleration immediately
after selecting a gear will
cause harsh engagement and
premature transmission
wear.

NOTE:Your car is equipped
with a KEYLOCK system.
When the engine is switched
off, the gear selector must be in
the (P)ark position before the
key can be removed from the
ignition switch.

Engine warm-up - initial
driving procedure

Engines in vehicles driven short
distances are subject to
abnormally rapid wear because
the engine never reaches normal
operating temperature. It is
therefore beneficial to reach
normal operating temperature as
soon as possible. This is best
achieved by driving with a light
foot on the accelerator pedal for
a few minutes after starting,
rather than prolonged idling.

B6304 S Engine


This engine features hydraulic
valve lifters which means that
valve clearance is adjusted
automatically. It is possible that
the valve lifters will produce a
ticking sound for the first few
seconds after the engine is
started, while the oil pressure is
increasing.
If the car has not been used for a
long period of time, this ticking
sound may last for up to 15
minutes. This is entirely normal.
