vehicle serviced promptly, because an
adult-size person sitting in the right front
passenger's seat may not have the protection
of the frontal airbag. See Airbag Readiness
Light on page 3-31 for more on this, including
important safety information.
Aftermarket equipment, such as seat covers, can affect
how well the passenger sensing system operates.
You may want to consider not using seat covers or other
aftermarket equipment if your vehicle has the passenger
sensing system. See Adding Equipment to Your
Airbag-Equipped Vehicle on page 1-62 for more
information about modifications that can affect how the
system operates.
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.
