9 Danger
Deactivate passenger airbag only

child restraint system, subject to
the instructions and restrictions in
the tables 3 52.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
Seats, restraints
If the control indicator V illuminates
for approx. 60 seconds after the
ignition is switched on, the front
passenger airbag system will inflate
in the event of a collision.
If both control indicators are
illuminated at the same time, there is
a system failure. The status of the
system is not discernible, therefore
no person is allowed to occupy the
front passenger seat. Contact a
workshop immediately.
Change status only when the vehicle
is stopped with the ignition off.
Status remains until the next change.
Control indicator for airbag
deactivation 3 90.
