Master Light
These are both Master Dashboard Warning Light and Attention symbols, in red. If this light is on, there will likely be text displayed as well on the instrument panel, or another warning light. Look for text in particular. It could very well point out something as serious as low oil pressure. However, despite the serious look to the symbol, it is generally associated with simple reminders such as a door ajar or that it is time to change the oil.

So, what’s up with the next one??
This same symbol, an exclamation point in a triangle, in yellow/amber has been used by European and Asian vehicle manufacturers in two ways. First, it indicates a fault in the vehicle’s Stability Control System, as well as a slip indicator. Click here for more. The vehicle can be driven with caution, but without the benefit of the advanced electronic control system.
Second, it is used in many cases to indicate that a text warning is available in the vehicle’s Information Display. It may involve a malfunction in any system. A Check Control message will likely require changing screens to discover the root problem.

And then there are these, which feature a lower case letter “i” in a square. It too is meant to alert the driver to look for a message in the information center, but the message will not involve a serious drivability issue. The manufacturer uses the red triangles for this. It may be seen in yellow/amber or black and white.
If you’re seeing red, see your dealer or authorized service center as soon as possible.
