Dashboard warning lights can be a source of anxiety for many drivers. A sudden illumination of an unfamiliar symbol can lead to confusion and concern about potential vehicle malfunctions. The Nissan Sentra, like many modern vehicles, is equipped with a variety of dashboard symbols that inform the driver about the car's status, from minor alerts to serious warnings that require immediate attention.

Understanding Dashboard Symbols

The master warning light appears as an exclamation point inside a triangle. It signifies that one or more systems in the vehicle require attention. This could range from low washer fluid to an open door. If this light activates, check your vehicle information display for specific alerts.

The check engine light (CEL) is one of the most recognized symbols among drivers. It indicates that the vehicle's onboard diagnostics system has detected an issue with the engine or its components. Common causes include:
- Loose or damaged gas cap
- Faulty oxygen sensor

Ignoring this light can lead to significant engine problems, so it’s advisable to have it checked promptly.
Brake Warning Light
This light may illuminate as either the word "BRAKE" or an exclamation point within a circle. It can indicate:

If this light remains on while driving, it’s crucial to stop and investigate immediately.

Failure to address this warning can lead to a dead battery or electrical failure.
