The instrument panel or panel, which is located on the dash behind the steering wheel, describes a set of indicators that provide the driver with all the necessary information on each of the vehicle’s systems or components.
If we refer to the most basic configurations, it is composed of the speedometer, tachometer, remaining fuel indicator and the engine temperature indicator.
However, as time has passed, this component has evolved in such a way that today it includes, in addition to the previous one, much more data in analog or digital format, or in a combination of both, such as fuel consumption in time. real.
In addition to the clocks, there are also a series of intermittent indicator lights, which can be preventive, informative or of some failure, and which account for the oil pressure and inflation in the tires, the battery charge, the level of brake fluid, among many others.
To understand it better, many of the electrical terminals of all systems reach the instrument panel and its objective is to establish a means of communication with the operator while the car is running, and it is divided into three groups that we will explain below.
1. Exclusive instruments to control the technical performance indexes of the vehicle. Typically on a dashboard, depending on the vehicle model, the following controls can be found:
Fuel level gauge. It is responsible for providing information related to the level of fuel in the tank.
Speed indicator. It allows the driver to know the speed at which the vehicle is moving.
Oil pressure gauge. It informs about the pressure of this fluid inside the engine. Proper oil pressure allows all internal components to be properly lubricated and thus prevents wear.
Coolant temperature gauge. It is a thermometer that warns us of any sudden variation in temperature in the engine.
Battery charge level indicator. If the accumulator does not receive enough charge, it can stop working, since all cars need electrical energy to start and continue their operation.
2. Alarm signals. Better known as witnesses, they can be audible, luminous or both and are in charge of informing the driver in the event of failures in any of the important vehicle systems.
When the lights on the dashboard light up green or blue, it indicates that everything is working properly in the vehicle.
The alarm signals that light up in yellow are a warning to the driver, that is, that it is possible to continue driving with some of the limited functions, but the vehicle is presenting faults, so it is necessary to seek technical advice depending on the warning light that is present. lit on the dash.
As users, we must be very attentive if the dashboard indicates an alarm signal in red, since the vehicle is definitely presenting an alert for which it needs to stop and seek help immediately.
3. Warning signs. These types of signals warn the driver about the operating status of some of the systems that make up the vehicle and that are under his responsibility, in order to make the pertinent modifications and guarantee the good performance of the car. The following examples are found in this group of signals.
Tire pressure monitoring. It warns the driver of the loss of air inside any of the four tires, which can be caused by a puncture.
Door Sensor. It lights up in red, indicating that one or more of the vehicle’s doors are not properly closed.
Brakes. If it appears on and in red, it informs the driver that the brake fluid level is very low, a delicate situation because without brake fluid these do not work properly.
High beam indicator. It is usually blue in color and indicates that the high beams are active.
Now that we have a clearer idea of how the instrument panel of our car works, it is important to be aware of the information it displays and thus prevent any damage to the systems that comprise it.
