Airbag Warning Light
You will want to have the airbag system ready to inflate
for your protection in an impact. The airbag system is
designed to be maintenance free. If any of the following
occurs, have an authorized dealer service the system
promptly:
•
Airbag Warning Light does not come on during the six
to eight seconds after the ignition switch is first turned
on,
•
Remains on after the six to eight second interval, or
•
Flickers, or comes on and remains on for any period of
time while driving.
NOTE: If the speedometer, tachometer, or any engine
related gauges are not working, the airbag control mod-
ule may also be disabled. The airbags may not be ready
to inflate for your protection. Promptly check the fuse
block for blown fuses. Refer to “Fuses” in Section 7 of this
manual. See your authorized dealer if the fuse is good.
Event Data Recorder (EDR)
In the event of an accident, your vehicle is designed to
record up to five seconds of specific vehicle data param-
eters (see the following list) in an event data recorder
prior to the moment of airbag deployment, or near
deployment, and up to one-quarter second of high-speed
deceleration data during and/or after airbag deployment
or near-deployment. EDR data are ONLY recorded if an
airbag deploys, or nearly deploys, and are otherwise
unavailable.
NOTE:
•
A near-deployment event occurs when the airbag
sensor detects severe vehicle deceleration usually in-
dicative of a crash, but not severe enough to warrant
airbag deployment.
