bringing us closer to our goal.

After Volvo cars and parts have fulfilled their
use, recycling is the next critical step in
completing the life cycle. The metal content is
about 75% of the total weight of the car, which
makes the car among the most recycled
industrial products. In order to have efficient
and well controlled recycling, many Volvo
variants have printed dismantling manuals
indication the weight and material of
individual components. For Volvo, all
homogeneous plastic parts weighing more than
1.7 oz. (50 grams) are marked with
international symbols that indicate how the
component is to be sorted for recycling.

Contents

Important

Before you operate your car for the first
time, please familiarize yourself with
the BREAK-IN information on page 54.
You
should also be familiar with the information
in the first three chapters of this book.
Information contained in the balance of the
manual is extremely useful and
should be studied after operating the vehicle
for the
first time. This manual is structured so that
it can be used for reference. It should thus
be kept in the car for ready access.

Chapter 1 - Occupant safety
VOLVO SRS
pg. 4
VOLVO SRS
As an enhancement to the three-point seat belt
system, your Volvo is equipped with a
Supplemental Restraint System (SRS). The Volvo
SRS consists of airbags (2) and knee bolsters (5)
on both the driver's and passenger's sides and seat
belt tensioners in both front door pillars (4). The
system is designed to supplement the protection
provided by the three-point seat belt system.

The SRS system is indicated by the "SRS"
embossed on the steering wheel pad and above
the glove compartment, the knee bolsters beneath
the steering column and the glove compartment
and decals on both sun visors and on the far right
side of the dash.

The airbags are folded and located in the center of
the steering wheel and above the glove
compartment. They are designed to deploy during
certain frontal or front-angular collisions,
impacts, or decelerations, depending on the crash
severity, angle, speed and object impacted. Both
airbags and seat belt tensioners will deploy, even
if the passenger seat is not occupied.
The airbag system includes gas generators (1)
surrounded by the airbags (2) and front seat belt
tensioners for both of the front seats (4). To deploy the
system, the sensor (3) activates the gas generators
causing the airbags to be inflated with nitrogen gas. As
the movement of the seats' occupants compresses the
airbags, some of the gas is expelled at a controlled rate
to provide better cushioning. Both seat belt tensioners
also deploy, minimizing any seat belt slack.

The entire process, including inflation and deflation of
the airbags, takes approximately two-tenths of a second.
WARNING!
When installing any optional equipment make sure
that the SRS system is not damaged. Do not attempt
to service any component of the SRS yourself.
Attempting to do so may result in serious personal
injury. If a problem arises, take your car to the
nearest authorized Volvo Retailer for inspection as
soon as possible.

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.

NOTE:The information on this page does not pertain
to the Side Impact Protection System airbags.

When are the airbags deployed?

The SRS system is designed to deploy during certain
frontal or front-angular collisions, impacts, or
decelerations, depending in the crash severity, angle,
speed, and object impacted. The SRS sensor is
designed to react to both the impact of the collision
and the inertial forces generated by it and to
determine if the intensity of the collision is sufficient
for the airbags to be deployed.
WARNING! The SRS is designed to help prevent
serious injury. Deployment occurs very quickly
and with considerable force. During normal
deployment and depending on variables such as
seating position, one may experience abrasions,
bruises, swellings, or other injuries as a result of
airbag(s) deployment.
Seat belts - the heart of the Volvo safety
system

The heart of the Volvo safety system is the three-
point seat belt (a Volvo invention)! In order for the
SRS system to provide the protection intended, seat
belts must be worn at all times by everyone in the car.
The SRS system is a supplement to the seat belts.
WARNING! If your car has been subjected to
flood conditions (e.g. soaked carpeting/standing
water on the floor of the vehicle) or if your car has
become flood-damaged in any way, do not
attempt to start the vehicle or put the key in the
ignition before disconnecting the battery (see
below). This may cause airbag deployment which
could result in personal injury. Have the car towed
to an authorized Volvo retailer for repairs.

SIPS airbag decal*
SIPS airbag (front seats only)
As an enhancement to the structural Side
Impact Protection System built into your
car, your car is also equipped with Side
Impact Protection System (SIPS) airbags.
The SIPS airbag system consists of airbag
modules built into the sides of both front
seat backrests (1), cables (2) from these
modules to the mechanical sensor units (3)
and gas generators (4).
The SIPS airbag system is designed to help
increase occupant protection in the event of
certain side impact collisions. The SIPS
airbags are designed to deploy only during
certain side-impact collisions, depending on
the crash severity, angle, speed, and point of
impact. The airbags are not designed to
deploy in all side impact situations.
covers may be
used. The use of
non-approved
aftermarket seat
covers may impede
SIPS airbag
deployment.
l No objects,
accessory
equipment or
stickers may be
placed on, attached
to or installed near
the SIPS airbag
system or in the
area affected by
SIPS airbag
deployment (see
illustration to the
right above).
l Never try to open
or repair any
components of the
SIPS airbag system.
This should only be
done by an
authorized Volvo
service technician.
l For best protection
from the SIPS
airbag system, both
front seat occupants
should sit in an
upright position
with the seat belt
properly fastened.
NOTE: SIPS airbag
deployment (one airbag)
occurs only on the side of
the vehicle affected by the
impact.

WARNING!
l Never drive with the
airbags deployed. The
fact that they hang out
can impair the steering
of your car. Other
safety systems can
also be damaged. The
smoke and dust
formed when the
airbags are deployed
can cause skin and eye
irritation in the event
of prolonged
exposure.
l If your car has been
subjected to flood
conditions (e.g.
soaked carpeting/
standing water on the
floor of the vehicle) or
if your car has become
flood-damaged in any
way, do not attempt to
start the vehicle or put
the key in the ignition
before disconnecting
the battery. This may
cause airbag
deployment which
could result in
personal injury. Have
the car towed to an
authorized Volvo
retailer for repairs.

Anti-lock Brake
System (ABS)

If the warning lamp lights up
there is a malfunction of the
ABS system (the standard
braking system will however
function). The vehicle should be
driven to a Volvo retailer for
inspection.
See page 67 for additional
information.
Canadian models are equipped
with this warning light:


Mode "W" engaged

The lamp will light up when the
Winter/Wet mode is engaged.
If the warning lamp begins to
flash,this means that there is a
fault in the automatic gearbox.
Contact your Volvo retailer.
Supplemental
Restraint System

If the light comes on (or stays
on after the vehicle has started),
the SRS diagnostic system has
detected a fault. Drive to an
authorized Volvo retailer for an
inspection of the system. See
the SRS section for more
information.

Service reminder
indicator

This light will come on at
10,000 mile (16,000 km)
intervals. It is a reminder to the
driver that the 10,000 mile
(16,000 km) service interval has
been exceeded. The light will
stay on 2 minutes after start
until reset by the servicing
retailer.

Coolant level sensor

If the light comes on while
driving, the coolant level is low.
The coolant level in the
expansion tank should be
checked immediately and
topped off if necessary. The
cooling system should be
inspected by an authorized
Volvo retailer.
Turn signal indicators-
trailer (certain models)

When towing a trailer, this light
will flash simultaneously with
the turn signals on the trailer. If
the light does not flash when
signaling, neither the trailer's turn
signals nor the car's turn signals
are functioning.

Bulb failure warning
light

The light will come on if any of
the following bulbs are defective:
one of the low beam headlights
one of the tail lights
one of the brake lights when the
brake pedal is depressed.

ECC - Electronic Climate Control

This is an automatic system that also permits
manual operation. The in-car temperature is
automatically monitored by two sensors located in
the passenger compartment.
One sensor is located on the top of the dashboard
where it can sense sunlight. The second sensor is
located on the courtesy light fixture where it can
sense the temperature in the center of the car. The
following pages describe how ECC works and
how it can be used most effectively.

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 2 lbs
(0.9 kg) R134a and uses Sanden SP-20 (type
PAG) oil.
