Deactivate passenger airbag only
in combination with the use of a
child restraint system, subject to
the instructions and restrictions in
the table 3 67.
Otherwise, there is a risk of fatal
injury for a person occupying a
seat with a deactivated front
passenger airbag.
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 the control indicator * illuminates
after the ignition is switched on, the front passenger airbag system is
deactivated. It stays on while the
airbag is deactivated.
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.
Consult a workshop immediately if
