Understanding the Maintenance Required Light on a 2020 Toyota Highlander

Tools Required

OBD-II Scanner (Optional): To check for any additional fault codes that may be stored in the vehicle’s computer.
Owner's Manual: For reference on maintenance schedules and reset procedures.
Ratcheting Socket Set: In case any physical maintenance tasks need to be performed.
Service Manual: For detailed service procedures if deeper inspections are required.
Diagnostic Software: If available, for a more in-depth look at the vehicle’s condition.

Repair Instructions

Step 1: Identify Maintenance Needed

Review Maintenance Schedule: Check the maintenance interval for oil changes, tire rotations, and other services as outlined in your owner’s manual. For the 2020 Toyota Highlander, oil changes are typically recommended every 5,000 to 10,000 miles, depending on oil type and driving conditions.

Step 2: Perform Required Maintenance

Oil Change:
- Gather tools: oil filter wrench, socket set, oil catch pan, new oil filter, and new oil.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the oil drain plug and allow old oil to drain into the catch pan.
- Replace the oil filter with a new one.
- Reinstall the drain plug and fill the engine with new oil.
Air Filter Replacement:
- Locate the air filter housing, usually near the engine intake.
- Remove the clips or screws securing the housing cover.
- Take out the old air filter and replace it with a new one.
Tire Rotation:
- Use a jack to lift the vehicle and secure it with jack stands.
- Loosen lug nuts and remove the wheels.
- Rotate the tires according to the recommended pattern (front-to-back, or side-to-side).
- Reinstall the wheels and lug nuts, tightening them in a crisscross pattern.

Step 3: Reset the Maintenance Light

Turn On the Ignition: Do not start the engine. Just turn the key or press the “Start” button until the dash lights come on.
Navigate to Settings: Use the menu button on the steering wheel to navigate to the “Settings” or “Maintenance” menu on the multi-information display (MID).
Select Maintenance Reset: Choose the option to reset the maintenance light. Confirm the reset when prompted.
Verify Reset: Turn off the ignition and then turn it back on to check that the maintenance required light is off.

Conclusion

The maintenance required light on your 2020 Toyota Highlander is an important reminder for regular vehicle upkeep. If the light is illuminated, it’s crucial to check the maintenance schedule and perform any required services. Resetting the light after maintenance is completed ensures you are aware of when the next service is due. If issues persist after maintenance, further diagnostics may be necessary.
