Hyundai Elantra MD/UD: Air bag warning light
This warning light will illuminate for approximately 6 seconds each time you turn the ignition switch to the ON position.
This light also comes on when the Supplemental Restraint System (SRS) is not
working properly. If the SRS air bag warning light
does not come on, or continuously remains
on after operating for about 6 seconds when you turned the ignition switch to the
ON position or started the engine, or if it comes on while driving, have the SRS
inspected by an authorized HYUNDAI dealer.
