Medical Condition.A passenger has a
medical condition which, according to his or
her physician:

causes the passenger airbag to pose a special risk
for the passenger; and
makes the potential harm from the passenger
airbag in a crash greater than the potential
harm from turning off the airbag and allowing the
passenger, even if belted, to hit the dashboard
or windshield in a crash.
{CAUTION:
If the right front passenger’s airbag is turned off
for a person who is not in a risk group identied
by the national government, that person will not
have the extra protection of an airbag. In a
crash, the airbag will not be able to inate and
help protect the person sitting there. Do not turn
off the passenger’s airbag unless the person
sitting there is in a risk group.To turn off the right front passenger’s airbag, insert your
ignition key into the switch, push in, and move the
switch to the off position.
The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The airbag off
light will stay on to remind you that the airbag is off. The
right front passenger’s airbag will remain off until you
turn it back on again.United States
Canada
1-66

{CAUTION:
If the airbag readiness light ever comes on
when you have turned off the airbag, it means
that something may be wrong with the airbag
system. The right front passenger’s airbag
could inate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identied as a
member of a passenger airbag risk group sit in
the right front passenger’s position (for
example, do not secure a rear-facing child
restraint in the right front passenger’s seat)
until you have your vehicle serviced. See
Airbag Readiness Light on page 3-32for
additional information.To turn the right front passenger’s airbag on again,
insert your ignition key into the switch, push in,
and move the switch to the on position.United States
Canada

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. You do not want the system to
inate while someone is working on your vehicle. Your
dealer and the service manual have information
about servicing your vehicle and the airbag system. To
purchase a service manual, seeService Publications
Ordering Information on page 7-15.
{CAUTION:
For up to two minutes after the ignition key 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 wires,
wires wrapped with yellow tape or 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.
The airbag system does not need regular maintenance.
