Generally, no special maintenance is required. As long as the "SRS / AIRBAG" warning light on the dashboard starts the self-check process for a few seconds and then goes off, it indicates normal operation. If any of the following situations occur, immediate repair is necessary:

• After startup, the SRS indicator light remains constantly on or does not go out
• A collision occurred (even though it did not explode)
• The vehicle has been submerged in water severely or the steering wheel/airbag module has been disassembled or assembled

Generally, manufacturers recommend that the airbag system be inspected every 10 to 15 years or as per the maintenance manual. Some brands specify that the entire module should be replaced when it becomes old.

Yes. For most GMC models such as Yukon, Sierra, and Terrain, the panel in the center of the steering wheel, which has the GMC logo on it, is directly beneath the driver's frontal airbag module. This panel is designed with a pre-set tear line. In the event of a collision, it will instantly burst open, allowing the airbag to deploy and protect the driver's head and chest.

The GMC model uses the SRS (Supplemental Restraint System) from General Motors.

Meaning of the name: SRS indicates that it is an "auxiliary" system and must be used in conjunction with seat belts.

Technical Feature: Modern GMC models (such as Yukon Denali, Sierra 1500) are usually equipped with dual-stage airbags. The ECU will control the inflation intensity (moderate or intense) based on the severity of the collision to reduce the impact injury caused by the airbags themselves to the driver.

No.

Driver's airbag: As per safety regulations, it is always activated and cannot be manually deactivated.

Side airbag for the co-pilot: Most GMC models (especially older models with a switch or specific market models) allow it to be turned off through the keyhole on the glove compartment or via the central control panel, but not for the driver's side.
