 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.

Indicates the temperature 
slightly above the surface of the 
road. An amber warning lamp 
lights up when the temperature 
is in the range of 23-36° F (-5 - 
+ 2° C). At low speeds or when 
the car is not moving, the 
temperature readings may be 
slightly higher than the actual 
ambient temperature due to heat 
generated by the engine.

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.
