What does the light symbol on whose car mean? The sign marked with a cross light bulb comes from Audi.

1, exhaust temperature warning lamp

Modern cars are equipped with a three-way catalyst on the exhaust pipe, so the exhaust temperature rises, but too high exhaust temperature is easy to damage the three-way catalyst, so this kind of cars have exhaust temperature alarm devices.

2. Brake the anti-lock warning light.

The anti-lock braking warning light is yellow (or amber) with the word "ABS" in the circle.

For an automobile equipped with anti-lock braking system (ABS), when the ignition switch is turned to the "on" position, the ABS warning light on the dashboard lights up for 3 s 6 s, which is a self-inspection process of ABS and is a normal phenomenon. As soon as the self-inspection process is over, if the ABS is normal, the alarm light will go out.

3. Airbag warning light

There are three display modes of the AIR BAG system (SRS) indicator light, one is the word "SRS", the other is the word "air bag" (produced by Toyota before August 1992), and the third is the graphic of "airbag protects passengers".
