Signal Lights
Dashboard warning lights include the amber and red lights. These momentarily illuminate when you turn on your engine, but if they do so while it is running, they might be a sign of issues with the main systems of the car.
If there are major issues with these systems, it is frequently advisable to have your Nissan Altima towed if the nearest service facility is not very nearby.
- The anti-lock braking system is denoted by the huge, bold letters ABS. When you turn on your engine, this light will blink to show that the system is operational. You should have your anti-lock braking system checked if this signal ever shows at any other time.
- There are two brake warning lights: a capital “BRAKE” word and an exclamation point in a ring. These illuminate when the parking brake is engaged, therefore if you notice them when you aren’t using the parking brake, you should immediately check the level of your brake fluid and have your brakes examined.

Check all four tires while the automobile is stopped, then reflate as required.
- When the pressure monitor system activates after you have changed the pressure and drove at 16 mph, the tire pressure light will turn off. You should get your tire pressure monitor system checked if, after starting your automobile, the tire pressure indicator continues to flash for a full minute.
- In addition to various warning lights like the tire pressure, low gasoline, low washer fluid, loose fuel cap, no key, parking brake release, and door or trunk open warnings, there is also a master light that looks like an exclamation point inside of a triangle.
- The driver or front passenger hasn’t buckled their seat belt, according to a figure with a seat belt. This warning comes with a chime.
- Airbag: The airbag systems are represented by a sideways, belted figure confronting a circle. Have your air bags examined as soon as possible if it doesn’t illuminate when the engine starts, flashes, or stays on.

What use do master caution lights serve?
The installation of instruments serves the dual function of displaying current circumstances and alerting to undesirable conditions. To distinguish between distinct visual signals, uniform colors are employed. For instance, the color green denotes a favorable state of affairs. A dangerous condition that needs further monitoring is indicated by the color yellow. Unsatisfactory conditions are represented by the color red. These colors provide the pilot with quick-reference information, whether they are a component of the instrument face or of a visual warning system.
The majority of airplanes have annunciator lights, which turn on when something important happens. These show the aforementioned hues in a range of ways. Individual lights next to the corresponding cockpit instrument or a central display of all the lights for all the systems is typical. Each light is labeled or contains words to clearly and quickly identify any issue.
The condition of multiple systems and components must be known and kept up to date on complicated aircraft. A variety of systems and components require critical messages to be announced, hence centralized warning systems have been designed to do so in an easy-to-understand way. Finding a single annunciator panel and placing it someplace on the instrument panel will frequently do this. Depending on the manufacturer’s taste and the equipment installed, these analog aviation warning systems may appear differently in different types of aircraft. Fig. 10–128 As part of its previously mentioned flight control and monitoring capabilities, EFIS offers the annunciation of advisory and warning messages. The principal display unit is typically chosen as the site to show announcements.
In addition to an annunciator that outlines the issue, master caution lights are employed to alert the crew to a serious situation. These centrally wired master warning lights come on anytime any of the involved systems or parts need maintenance. The pilot is informed and has the option to dismiss the master caution, but until the issue that prompted the warning is resolved, a specific system or component annunciator light remains on. Even before the initial problem is fixed, canceling causes the master caution lights to be reset and warn of a later fault event. Image 10-129 The complete annunciator system has a press-to-test button that activates all of the warning circuits and lights to verify readiness. This test frequently reveals that the system’s tiny light bulbs need to be replaced.
Along with LED annunciator systems, aircraft have aural warning systems. They alert the pilot audibly when something needs their attention. To warn the crew of specific situations, the cockpit emits a variety of tones and phrases. For instance, an aural warning system is used to notify the crew of a hazardous situation in an aircraft with retractable landing gear. If the landing gear is not down and locked and the throttle is retarded, a bell will sound.
An aural warning system is typically installed in a transport category aircraft to notify the pilot to unusual takeoffs, landings, pressurization, mach airspeed circumstances, engine or wheel well fires, calls from the crew call system, collision avoidance advice, and more. Some of the issues that result in audible alerts are depicted in Figure 10-130, along with the steps that should be followed to resolve them.
