under certain conditions.

The OWS uses a PASSENGER AIRBAG OFF

indicator lamp which will illuminate and stay on

to remind you that the passenger's side front

airbag is disabled. The PASSENGER AIRBAG

OFF indicator lamp is located in the overhead

console, near the base of the rearview mirror.

Disabling the passenger's side front

airbag

The OWS works with sensors that are part of

the front passenger's seat and seat belt. The

sensors are designed to detect the presence of

a properly seated occupant and determine if

the passenger's side front airbag should be

enabled (may inflate) or disabled (will not

inflate).

NOTE

When the ignition is switched on, the OWS

indicator light will go on for up to 10 seconds

while the system performs a self-diagnostic

test.

The OWS will disable (will not inflate) the pas-

senger's side front airbag when:

the front passenger's seat is unoccupied,

or has small/medium objects in the front

seat,

Volvo recommends that ALL occupants (adults

and children) shorter than 4 feet 7 inches

(140 cm) be seated in the rear seat of any vehi-

cle with a passenger's side front airbag, and be

properly restrained. Children should always be

seated in child restraints appropriate for their

size and weight. See also the child safety rec-

ommendations on page 38.

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.

Volvo 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 disable (will not inflate)

the passenger's side front airbag when a rear

restraint, or a booster seat is detected. The

WARNING

Keep the following points in mind with

respect to the OWS system. Failure to follow

these instructions could adversely affect the

system's function and result in serious injury

to the occupant of the front passenger's

seat:

No objects that add to the total weight

on the seat should be placed on the

front passenger's seat. If a child is

seated in the front passenger's seat

with any additional weight, this extra

weight could cause the OWS system to

enable the airbag, which might cause it

to deploy in the event of a collision,

thereby injuring the child.

The full weight of the front seat passen-

•

ger should always be on the seat cush-

ion. The passenger should never lift

him/herself off the seat cushion using

the armrest in the door or the center

console, by pressing the feet on the

floor, by sitting on the edge of the seat

cushion, or by pressing against the

backrest in a way that reduces pressure

on the seat cushion. This could cause

OWS to disable the passenger's side

front airbag.

The seat belt should never be wrapped

around an object on the front passeng-

er's seat. This could interfere with the

OWS system's function.

•

In Canada

The front passenger's seat belt should

never be used in a way that exerts more

pressure on the passenger than normal.

This could increase the pressure exer-

ted on the weight sensor by a child, and

could result in the airbag being enabled,

which might cause it to deploy in the

event of a collision, thereby injuring the

child.
