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
identi ed 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
in ate 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.United States

The airbag off light will come on to let you know that the
right front passenger’s airbag is off. The 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.
{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 in ate even though the switch is off. If
this ever happens, do not let anyone whom the
national government has identi ed 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 3-29for
additional information.To turn the right front passenger’s airbag on, insert your
ignition key into the switch, push in, and move the
switch to the on position.United States

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
inflate 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 7-11.
{CAUTION:
For up to 10 seconds after the ignition key is
turned off and the battery is disconnected, an
airbag can still in ate during improper service.
You can be injured if you are close to an airbag
when it in ates. 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
quali ed to do so.
The airbag system does not need regular maintenance.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front of the
vehicle that could keep the airbags from
working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Also, the airbag system may
not work properly if you relocate any of the airbag
sensors. If you have any questions about this,
you should contact Customer Assistance before you
modify your vehicle. The phone numbers and
addresses for Customer Assistance are in Step Two
of theCustomer Satisfaction Procedure on
page 7-2.

At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
•Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
•Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
•Check to determine if battery replacement is
necessary. See “Battery Replacement” under
Remote Keyless Entry System Operation on
page 2-4.
•If you are still having trouble, see your dealer or a
qualified technician for service.
