Warning Lights for the 2022 Toyota Highlander

The 2022 Toyota Highlander features a variety of warning lights on its dashboard that indicate various issues or alerts regarding the vehicle's systems. Below is a detailed list of common warning lights, their meanings, and what actions should be taken if they illuminate.

1. Check Engine Light (Malfunction Indicator Lamp)

Symbol: Engine outline with an illuminated yellow/orange light.
Meaning: Indicates a problem with the engine or emissions system.
Action: Check for diagnostic trouble codes (DTCs) using an OBD-II scanner. If the light is steady, it may be safe to drive to a service center; if it is flashing, reduce speed and seek immediate assistance.

2. Oil Pressure Warning Light

Symbol: Oil can with a droplet.
Meaning: Low oil pressure or oil level.
Action: Pull over and check the oil level using the dipstick. If low, add oil. If the light remains on, there could be a serious issue, and the vehicle should not be driven.

3. Battery/Charging Alert Light

Symbol: Battery shape with a plus and minus sign.
Meaning: Charging system malfunction (such as a dead battery or faulty alternator).
Action: Check battery connections for corrosion or looseness. If problems persist, have the battery and alternator tested.

4. Brake Warning Light

Symbol: Exclamation mark inside a circle or "BRAKE" text.
Meaning: This light can indicate several issues, including the parking brake being engaged, low brake fluid, or a malfunction in the braking system.
Action: Check if the parking brake is engaged. If it’s off and the light remains illuminated, check brake fluid levels. If low, refill and inspect for leaks. If still on, seek professional assistance.

5. Tire Pressure Warning Light

Symbol: Tire with an exclamation mark inside.
Meaning: Indicates that one or more tires are under-inflated.
Action: Check tire pressures and inflate to the recommended levels. If the light does not turn off after correcting tire pressure, have the system checked for faults.

6. Anti-lock Brake System (ABS) Warning Light

Symbol: Circle with "ABS" inside.
Meaning: Indicates a malfunction in the ABS.
Action: If the light comes on, the ABS may be disabled. Regular brakes will function normally, but have the ABS system diagnosed.

7. Traction Control Warning Light

Symbol: Car with squiggly lines beneath it.
Meaning: Indicates that the traction control system is active or has detected a fault.
Action: If it’s flashing, it means the system is working to maintain traction. If it stays on, have the system checked.

8. Lane Departure Alert (LDA) Warning Light

Symbol: Car with lane markings on either side.
Meaning: Alerts the driver if the vehicle is unintentionally drifting out of its lane.
Action: Check the lane assist settings. If the light stays on, ensure that the cameras and sensors are clean, and seek professional diagnostics.

9. Forward Collision Warning Light

Symbol: Car with an exclamation mark in front.
Meaning: Indicates that the vehicle's pre-collision system has detected a potential collision.
Action: Maintain distance from other vehicles. If the light stays on, it may need calibration or repairs.

10. Engine Coolant Temperature Warning Light

Symbol: Thermometer submerged in liquid.
Meaning: Indicates that the engine is overheating.
Action: Pull over safely, turn off the engine, and allow it to cool. Check coolant levels and inspect for leaks. Do not open the radiator cap until the engine is cool.
