Seat belts

The seat belts are locked during

heavy acceleration or deceleration of

the vehicle holding the occupants in

the sitting position. Thereby the risk of

injury is considerably reduced.

9 Warning

Fasten seat belt before each trip.
In the event of an accident, people

not wearing seat belts endanger

their fellow occupants and

themselves.

Seat belts are designed to be used by

only one person at a time. They are

not suitable for people smaller than

150 cm. Child restraint system

 60.

Periodically check all parts of the belt

system for damage and proper

functionality.
Have damaged components

replaced. After an accident, have the

belts and triggered belt pretensioners

replaced by a workshop.

Note

Make sure that the belts are not

damaged by shoes or sharp-edged

objects or trapped. Prevent dirt from

getting into the belt retractors.

Seat belt reminder X 3 96.

Belt force limiters

Stress on the body is reduced by the

gradual release of the belt during

a collision.

Belt pretensioners

In the event of a head-on or rear-end

collision of a certain severity, the front

seat belts are tightened.

9 Warning

Incorrect handling (e.g. removal or

fitting of belts) can trigger the belt

pretensioners.

Deployment of the belt pretensioners

is indicated by continuous illumination

of control indicator v 3 96.
Triggered belt pretensioners must be

replaced by a workshop. Belt

pretensioners can only be triggered

once.

Note

Do not affix or install accessories or

other objects that may interfere with

the operation of the belt

pretensioners. Do not make any

modifications to belt pretensioner

components as this will invalidate

the vehicle type approval.

Airbag system

The airbag system consists of

a number of individual systems

depending on the scope of

equipment.
When triggered the airbag inflates

within milliseconds. They also deflate

so quickly that it is often unnoticeable

during the collision.

9 Warning

If handled improperly the airbag

systems can be triggered in an

explosive manner.

Note

The control electronics of the airbag

systems, belt pretensioners and

deployable anti-roll bars are located

in the centre console area. Do not

put any magnetic objects in this

area.
Do not stick anything on the airbag

covers and do not cover them with

other materials.

Each airbag/anti-roll bar is triggered

only once. Have deployed airbags/

anti-roll bars replaced by

a workshop. Furthermore, it might be

necessary to have the steering

wheel, the instrument panel, parts of

the panelling, the door seals,

handles and the seats replaced.
Do not make any modifications to

the airbag system/anti-roll bars as

this will invalidate the vehicle type

approval.

When the airbags inflate, escaping

hot gases may cause burns.
Control indicator v for airbag systems

and anti-roll bars 3 96.

Front airbag system

The front airbag system consists of

one airbag in the steering wheel and

one in the instrument panel on the

front passenger side. These can be

identified by the word AIRBAG.

58

Seats, restraints

There is also a warning label on the

side of the instrument panel, visible

when the front passenger door is

open.
The front airbag system is triggered in

the event of a front-end impact of

a certain severity. The ignition needs

to be switched on.

The inflated airbags cushion the

impact, thereby reducing the risk of

injury to the upper body and head of

the front seat occupants

considerably.

9 Warning

Optimum protection is only

provided when the seat is in the

proper position 3 49.
Keep the area in which the airbag

inflates clear of obstructions.

Fit the seat belt correctly and

engage securely. Only then the

airbag is able to protect.

Side airbag system

The side airbag system consists of an

airbag in each front seat backrest.

This can be identified by the word

AIRBAG.
The side airbag system is triggered in

the event of a side impact of a certain

severity. The ignition needs to be

switched on.

Seats, restraints

59

The inflated airbags cushion the

impact, thereby reducing the risk of

injury to the upper body and pelvis in

the event of a side-on collision

considerably.

9 Warning

Keep the area in which the airbag

inflates clear of obstructions.

Note

Only use protective seat covers that

have been approved for the vehicle.

Be careful not to cover the airbags.

Curtain airbag system

The curtain airbag system consists of

an airbag in the roof frame on each

side. This can be identified by the

word AIRBAG on the roof pillars.
The curtain airbag system is triggered

in the event of a side-on impact of

a certain severity. The ignition needs

to be switched on.

The inflated airbags cushion the

impact, thereby reducing the risk of

injury to the head in the event of

a side-on impact considerably.

9 Warning

Keep the area in which the airbag

inflates clear of obstructions.
The hooks on the handles in the

roof frame are only suitable for

hanging up light articles of

clothing, without coat hangers. Do

not keep any items in these

clothes.

Seat occupancy

recognition

60

Seats, restraints

Identified by a label on the lower

panel of the front passenger seat and

by control indicator y, which

illuminates for approx. 4 seconds

when the ignition is switched on.
The seat occupancy recognition

system deactivates the passenger

front and side airbag if the front

passenger seat is not occupied or is

fitted with an Opel child restraint

system with transponders. The

curtain airbag system remains

activated.

9 Danger

Only Opel child restraint systems

with transponders should be fitted

on the front passenger seats. Use

of systems without transponders

poses a risk of fatal injury.

Control indicator 3 96.

Note

Anyone weighing less than 35 kg

should only travel on the rear seats.
Do not place any heavy objects on

the front passenger seat. Otherwise

the seat will register as occupied and

the airbag system for the front

passenger seat will not be

deactivated.
Do not use protective covers or seat

cushions on the front passenger

seat.
Note

On the Astra TwinTop, there may be

interference in radio reception of

certain frequencies in the medium

waveband when the roof is open and

the front passenger seat is

unoccupied.

Child restraints

Child restraint systems

We recommend the Opel child

restraint system which is tailored

specifically to the vehicle.
When a child restraint system is being

used, pay attention to the following

usage and installation instructions

and also those supplied with the child

restraint system.
Always comply with local or national

regulations. In some countries, the

use of child restraint systems is

forbidden on certain seats.

Selecting the right system

The rear seats are the most

convenient location to fasten a child

restraint system.
Children should travel facing

rearwards in the vehicle as long as

possible. This makes sure that the

child's backbone, which is still very

weak, is under less strain in the event

of an accident.

Seats, restraints

61

Children under the age of 12 years

that are smaller than 150 cm are only

allowed to travel in a restraint system

that is suitable for the child. Suitable

are restraint systems that comply with

ECE 44-03 or ECE 44-04. Since

a proper position of the belt is rarely

possible with a child that is smaller

than 150 cm, we strongly advise to

use an appropriate child restraint

system, even though this might, due

to the age of the child, no longer be

legally binding.
Ensure that the child restraint system

to be installed is compatible with the

vehicle type.
Ensure that the mounting location of

the child restraint system within the

vehicle is correct.
Allow children to enter and exit the

vehicle only on the side facing away

from the traffic.
When the child restraint system is not

in use, secure the seat with a seat belt

or remove it from the vehicle.

Note

Do not stick anything on the child

restraint systems and do not cover

them with any other materials.
A child restraint system which has

been subjected to stress in an

accident must be replaced.
