Yellow (sometimes orange) dashboard lights usually mean something needs to be repaired or serviced soon and to operate with caution. Green (sometimes blue) dashboard lights usually indicate a system is on or is operating, and the light is giving you a visual cue.Īdditionally, it is important to know a flashing dashboard warning light is used to inform the driver of a state of urgency related to the system referenced by the light. You should study the owner's manual for your vehicle and learn the meaning of each specific dashboard light applicable to your vehicle. While dashboard lights may vary by vehicle, the following are some examples of very common warning and informational lights that could appear on the dashboard of your vehicle: This will help you to be better prepared in the event one of the warning lights comes on and also to understand what all of the dashboard lights mean. The brake system light could mean the brake fluid level is low, the parking brake is on or there is an issue with the anti-lock braking system (ABS). Perform a quick visual inspection to see if the parking brake is engaged and inspect the brake fluid level to ensure it is full. This warning light could be serious if it is related to a loss of brake fluid due to a leak. The engine coolant temperature warning light is serious and indicates your engine is too hot, or your coolant level is low or the vehicle may have a faulty coolant temperature sensor. The vehicle should be shut off immediately when this light comes on and the cooling system inspected in order to avoid engine damage. The check engine light indicates the engine computer has set a diagnostic trouble code (DTC) in the engine management system and is usually related to emission control systems or running concerns. The vehicle still may appear to be running normally. A check engine light doesn't mean you have to immediately pull the car to the side of the road, but it should be inspected as soon as possible. A flashing check engine light requires immediate attention. The engine oil pressure warning light comes on when the oil pressure sensor detects low oil pressure. This could indicate low engine oil level, a loss of engine oil pressure or a faulty engine oil pressure sensor. The engine oil level and pressure should be checked immediately. Low oil level or low oil pressure will cause serious damage to the internally lubricated parts of the engine. The battery/charging light indicates the battery voltage level is below normal, and the charging system is not functioning properly. The alternator belt should be inspected, the battery terminals and connections inspected and the alternator should be tested. #FREIGHTLINER GREEN ENGINE LIGHT MANUAL#.#FREIGHTLINER GREEN ENGINE LIGHT DRIVER#. ![]()
