Repair Instructions:

Step 1: Reset the Maintenance Light

Turn the Ignition On:
- Insert the key fob into the ignition and turn it to the "ON" position without starting the engine.
Access the Odometer Display:
- Ensure that the odometer is displayed on the multi-information display (MID) screen.

Step 2: Perform Required Maintenance

Oil Change (if due):
- Lift the Vehicle: Use a jack and jack stands to elevate the vehicle safely.
- Drain Old Oil: Place an oil catch pan under the oil pan, remove the drain plug, and let the old oil drain completely.
- Replace Oil Filter: Use an oil filter wrench to remove the old filter. Install the new oil filter, ensuring a proper seal.
- Add New Oil: Replace the drain plug, and add fresh oil through the oil filler cap. Check the owner’s manual for the correct oil type and capacity.
- Check Oil Level: Use the dipstick to ensure the oil level is within the recommended range.
Tire Rotation (if due):
- Loosen Lug Nuts: Slightly loosen the lug nuts on all four tires.
- Lift the Vehicle: Use a jack to lift the vehicle and secure it with jack stands.
- Rotate Tires: Move the front tires to the rear and vice versa, ensuring to follow the correct rotation pattern.
- Tighten Lug Nuts: Reinstall and tighten all lug nuts in a criss-cross pattern to ensure even pressure.
Replace Air Filter (if due):
- Locate Air Filter Housing: Open the hood and find the air filter housing.
- Remove Old Filter: Unsnap or unscrew the housing and remove the old filter.
- Install New Filter: Place the new filter in the housing, ensuring it fits snugly.
Check Fluid Levels:
- Inspect and top off all essential fluids (brake, coolant, transmission, power steering, windshield washer fluid).
Inspect Brake Pads & Rotors (if necessary):
- Check the wear on brake pads and rotors. Replace if necessary.

Step 3: Final Check

After completing the maintenance, start the engine and check if the "Maintenance Required" light is off.
If the light remains illuminated after performing the necessary maintenance, consider consulting with a professional technician for further diagnostic testing.

Conclusion:

The "Maintenance Required" light in your 2018 Toyota Camry serves as an essential reminder for routine maintenance. By following the steps outlined above, you can ensure your vehicle remains in optimal condition and prevent potential issues down the line.
