Dashboard Indicator Lights

04/Feb/2023 393 |

The instrument panel on the dashboard has multiple gauges and indicators. The ones that are included in each vehicle will vary by make and model. A better resource to learn the meaning of each dashboard symbol for a specific vehicle is the owner’s manual for that vehicle.

  1. Dashboard lights can be red, orange (or yellow), or blue.
  2. Generally, when a red light comes on while driving, it means you should immediately pull over safely and call a tow truck. However, there are some exceptions – some lights which are generally red can be yellow or orange, and some red lights can be fixed immediately (seat belt light – put your seat belt on, door ajar light – close all the doors).
  3. Orange or yellow lights generally indicate that there is a problem with your vehicle, but it is safe to drive to a repair facility or your home residence to investigate further. 

The following are the general symbols:

Airbag Light or Supplemental Restraint Warning Light
Red, Orange, or Yellow. Whenever this light illuminates the airbag system senses a problem, which could be a safety issue. It doesn’t necessarily mean that the airbags will not work. The airbags might or might not still deploy during an accident. The light means that there is a part of the airbag system that may not work.
Anti-Lock Brakes Light
Orange or yellow light. This indicates a failure in the anti-lock brake (ABS) system and anti-lock brakes are disabled. The purpose of the ABS is to allow steering control of a vehicle while braking and to avoid skidding during a panic stop. If this light is on, then the normal conventional brake function will continue. If it’s on in the event of a panic stop then the vehicle will skid.
Brake Light
Red light, immediately pull over safely and have the vehicle towed (or disengage the parking brake if applicable). This light indicates that there is something wrong with the brakes. There could be a low brake fluid level, there could be a hydraulic brake failure, or the parking brake is engaged.
Change Oil Soon
Orange or yellow light. This light indicates that routine oil change and maintenance is due. It’s based on revolutions of the crankshaft, which is even more accurate than basing routine oil changes on mileage.
Check Engine Light
Red or yellow light. There is a problem with the vehicle emissions and the vehicle’s computer will have diagnostic trouble codes (DTCs) which will be retrieved when the vehicle is inspected. The light may come on and then off. If there are any performance issues with the way the vehicle is driving, then pull over and have it towed. If the light comes on and stays on, or comes on and then flashes during acceleration, then immediately pull over safely and have it towed to a shop.
Door Ajar Indicator Light
Red light. One of the vehicle doors is open. Close the open door before proceeding to drive. There may also be a separate light for the trunk.
High Beam Indicator or Brights.
Usually blue, but can be red on older vehicles. This indicates that your brights are on.
Low Coolant Level Light
Red, Orange, or yellow light. This light indicates that the engine coolant level is low, which could be due to a leak. It is still safe to drive as long as the engine temperature light is not on. In some vehicles, the first symbol above, the thermometer symbol, can also be a temperature light. Some vehicles can have a blue thermometer symbol. Consult the owner’s manual for its description.
Low Fuel Light
Yellow or Orange. This light indicates that fuel is low. It could also be a simple round light that illuminates when the fuel gauge is nearing empty.
Low Oil Level Light
Yellow or Orange. The oil level is low. Refill the oil as soon as possible and bring the vehicle to a shop to see why it was low.
Low Oil Pressure or Engine Oil Pressure Light
Red light (immediately pull over safely). Once you pull over you could check your oil level and add oil if it’s low. If the light continues to be illuminated then you should have your vehicle towed to a facility. Catastrophic engine failure will occur if the oil pressure is low. Repairs for these damages can be very expensive.
Parking Brake Light
Red light. The parking brake is engaged or not fully released. Release it completely before driving.
Service Vehicle Soon
Yellow light. This light may be used in conjunction with other lights. Depending on which other lights are illuminated, there may be a problem with the anti-lock brakes (ABS), brake hydraulic system, and traction control system (TCS).
Temperature Light (or Hot Light)
Red light (immediately pull over safely, turn off the engine, and have it towed). This light means engine temperature has exceeded maximum parameters. Severe engine failure will result if you continue to drive.
Throttle Control Warning Light
Yellow or orange. In some vehicles, the throttle has an electronic control system. These lights indicate that there is a problem with the system. Has the vehicle been serviced as soon as possible? In some makes and models, the wrench light can be for other purposes. Be sure to consult the owner’s manual.
Tire Pressure Warning Light
Yellow or orange. This light indicates that one or more of the tires has fallen below 25% of the recommended pressure. Have the tires checked soon?
Turn Signals and Hazard Light Display
These will only illuminate when a turn signal (left or right) or the hazard lights (both simultaneously) are turned on. If one stays on instead of blinking in rhythm or blinks slower or quicker than usual then there is a problem. One of the bulbs may need to be replaced or there is something wrong with the circuit.
Voltage Light.
Red Light (pull over safely and get it towed). If this particular light illuminates while you’re on the freeway then you may be able to proceed to the next exit. This light indicates that voltage is below the minimum specification and your vehicle will stop running once the battery dies. Safely pulling over and having the vehicle towed is even more important at night since you’ll lose the use of your headlights, which tend to drain the battery even quicker. Some of the samples are yellow; in this case, you should still treat it as a red light.
Security Light.
Red, Orange, or Yellow. This indicates that there is a problem with the theft deterrent system. Sometimes the vehicle will not run if this light illuminates or blinks.
Seat Belt Light.
Red light. This means that the driver and/or passenger do not have their seat belts fastened.
Traction Control Light or Low Track Light
Yellow, orange, or blue light. This indicates drive wheel speed is higher than the coasting wheel speed. For example, if you have front-wheel drive, then the front-wheel speed is higher than the rear-wheel speed. This can be useful on ice, dirt, or any low-traction condition. Be careful while driving in these conditions, especially when turning.
