Why Is My Airbag Light On?

You should never ignore the airbag light when it appears on your Mercedes-Benz's dashboard. In case of an accident, the airbags are a vital safety feature that could save your life and that of your passengers. If you see your airbag light is on, it could be one of the following issues:

Deployment Issues

If you see the airbag light, it could be a sign of problems with the vehicle's Supplemental Restraint System (SRS). It means the airbags will not deploy in case of an accident.
One or more of the airbags failing to open during a collision could be deadly. The airbags could still deploy even when there is an SRS problem, but it is best not to take a chance.

Seat Belts

A car's SRS is responsible for collision sensors, airbags, and seatbelt pretensioners. During an accident, the sensor will detect the forward momentum and lock the seatbelt pretensioners to keep you in your seat.
An issue with the pretensions will be signaled by the airbag light. When you see the sign, see an expert to get help with your car's SRS.

Crash Sensors

It is paramount that your vehicle's sensors function optimally. The sensors are a critical part of the SRS, which activate the airbags and seatbelt pretensioners for your protection in a collision.
When the crash sensors are damaged, they will not send the signal to the SRS to deploy the safety features. If you are involved in an accident and airbags don't deploy, fix the sensors.


An airbag warning light may be due to electrical or wiring issues, particularly if airbags do not deploy during a collision. It could also be a problem with the SRS computer. An advanced test of the electrical circuits and wiring is crucial to solving it.
