182 Airbag system
In conjunction with the three-point seat belts and side airbags, the
head-protection airbags give the occupants additional protection
against head and neck injuries in a severe side collision ⇒
"Important safety notes on the head-protection airbags" on
page 182.
Together with other design features (including cross-braces in the
seats and the overall strength of the body structure), the sideguard
system offers an effective further improvement to occupant protec-
tion in side impacts.
How the head-protection airbags work
When fully inflated, the airbags reduce the risk of head or
chest injury in a side collision.
In certain types of side collisions the head-protection airbag is trig-
gered together with the side airbag on the impact side of the vehicle
⇒ fig. 194.
When the system is triggered, the airbag fills with a propellant gas
and covers the entire area in front of the side windows, including
the door pillars. In this way the system is able to protect both the
front and the rear occupants on the side of the vehicle where the
impact occurs. The head-protection airbag inflates to soften the
impact if an occupant strikes parts of the interior or objects outside
the vehicle with their head. By reducing the head impact and
restraining uncontrolled movement of the head, the airbag also
reduces the forces acting on the neck. In addition, since it covers the
in front door pillar when fully inflated, the head-protection airbag also
gives extra protection if the car should collide with an obstacle at an
oblique angle.
The front airbags, side airbags and head-protection airbags may be
triggered together in certain types of accident.
In order to provide the desired extra protection in an accident, the
airbags have to inflate extremely rapidly (within fractions of a
second). The airbag releases a fine dust when it inflates. This is quite
normal and does not mean there is a fire in the vehicle.
Important safety notes on the head-
protection airbags
There are a number of safety points concerning the airbag
system which you should remember. This will help to
reduce the risk of injury in an accident.
WARNING
It is important to ensure that the area around the openings for

condition
The built-in coat hooks should only be used for lightweight
clothing. Do not leave any heavy or sharp-edged objects in the
pockets. When using the coat hooks, do not hang the clothes on
coat hangers.
The space between the passengers and the head-protection
airbags must never be occupied by children, other passengers or
pets. Passengers should never lean out or put a hand or arm out of
the window while the vehicle is in motion.
Do not move the sun visors out to cover the side windows if
there is anything attached to them (such as pens or a remote
