Airbag Warning Light (SRS) on a Lexus GS
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Airbag Warning Light (SRS) Means on a Lexus GS
On the Lexus GS, an illuminated airbag light indicates the SRS module found a problem in the airbag circuit, a seat-belt pretensioner, or a crash sensor. The system disables itself to avoid an unintended or failed deployment.
How Urgent Is the Airbag Warning Light (SRS)?
Urgency level for this indicator on the Lexus GS: high. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Airbag Warning Light (SRS) appeared, how the Lexus GS is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
