mation (  page 85). Also, always observe the 54
Occupant safety

notes on rearward-facing or forward-facing child
r estraint systems on the front passenger seat
(  page 84).
Information on automatic front passenger airbag
shutoM
Only when the PASSENGER AIR BAG OFF indica-
tor lamp is oM can the front passenger airbag
deploy in the event of an accident. If the front
passenger seat is occupied, make sure, both
before and during the journey, that the status of
the front passenger airbag is correct
(  page 59).
* NOTE Deplo
yment of components of the
restraint system when the front passenger
seat is unoccupied In an accident, the components of the
r
estraint system may deploy unnecessarily on
the front passenger side if:
= There are heavy objects on the front
passenger seat.
= The seat belt tongue is engaged in the seat
belt buckle of the front passenger seat and
the front passenger seat is unoccupied. 
Stow objects in a suitable place. 
Only one person should use each seat
belt at an
y one time. Depending on the detected accident situation, the
windo
w airbag on the front passenger side may
deploy. The airbag is deployed regardless of
whether the front passenger seat is occupied.
Information on the centre airbag
When triggered, the centre airbag deploys
between the front seats. Do not stow any objects
in the deployment area of the centre airbag.
Information on the rear airbag
Always observe the information on the rear air-
bag, especially in the following situations:
= A person is sitting on the outer rear seat.
= You install a child restraint system on the
outer rear seat.
= You stow objects behind the front seats.
Before beginning the journey, observe the infor-
mation on the rear airbag (  page 62). Be
aware of the status of the respective rear airbag depending on the situation both before and during
t

he journey (  page 63).
Information on the cushionbag in the reclining
rear seat
The cushionbag oMers additional occupant protec-
tion in the event of frontal impacts. When ena-
bled, the cushionbag deploys under the seat cush-
ion. This helps prevent the vehicle occupant from
slipping oM the seat cushion.
If you install a child restraint system on the reclin-
ing rear seat, always observe the additional notes
(  page 71). Protection provided by the airbags
Depending on the accident situation, an airbag
ma

y supplement the protection oMered by a cor-
rectly fastened seat belt. &
WARNING Risk of injur
