The passenger sensing system may suppress the
airbag deployment when liquid soaks into the seat.
If this happens, the off indicator in the passenger airbag
status indicator and the airbag readiness light on the
instrument panel will be lit. The system should resume
normal operation after the seat is allowed to dry. If
the system operates incorrectly after the seat has dried,
have your dealer/retailer check the system.
{CAUTION:
Stowing of articles under the passenger’s seat
or between the passenger’s seat cushion and
seatback may interfere with the proper
operation of the passenger sensing system.
Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the service
manual have information about servicing your vehicle and
the airbag system. To purchase a service manual, see
Service Publications Ordering Information on page 7-15.
{CAUTION:
For up to 10 seconds after the ignition is turned
off and the battery is disconnected, an airbag
can still inate during improper service. You
can be injured if you are close to an airbag when
it inates. Avoid yellow connectors. They are
probably part of the airbag system. Be sure to
follow proper service procedures, and make
sure the person performing work for you is
qualied to do so.
