Dashboard markings

Every year, the vehicle producers install the newest car systems, as well as functions with individual dashboard indicators and signs, reading them may be pretty hard. Moreover, function or system in vehicles from different manufacturers may have indicator that is not similar to the indicator of another brand.

In this article, we provide a list of dashboard displays that are used to alert the driver. It is not difficult to guess that the green display indicator reports on the work of one system or another. Yellow or red ones usually warn of the problem.

So let’s consider all the marks (lights) of the dashboard:

Warning Indicators

Handbrake is applied, there might be a low brake fluid level, as well as there is a possibility of the brake system malfunction.

Red color means cooling system overheat, blue means reduced temperature. Flashing indicator is a fault in the electrical parts of the cooling system.
