To reset the maintenance light, turn the ignition key to the 'ON' position without starting the engine. Ensure the odometer is set to 'ODO'. Turn the ignition key to the 'OFF' position.

The recommended tire pressure for a 2012 Toyota Corolla Sedan is typically 32 psi for both front and rear tires. Always check the owner's manual or the sticker on the driver's side door jamb for specific recommendations.

It is recommended to change the oil every 5,000 miles or six months, whichever comes first, when using conventional oil. If using synthetic oil, you may extend the interval to 7,500 to 10,000 miles. Always check the owner's manual for specifics.

The 2012 Toyota Corolla typically uses 0W-20 viscosity synthetic oil. However, 5W-20 can also be used if 0W-20 is not available. Always refer to the owner's manual for the most accurate information.

To replace the air filter, open the hood and locate the air filter box near the engine. Unclip or unscrew the fasteners to open the box. Remove the old filter and insert the new one, ensuring it fits snugly. Secure the air filter box with the fasteners.

A squealing noise upon starting could be due to a worn or loose serpentine belt. Inspect the belt for any signs of wear or damage, and if necessary, replace or tighten it. If the problem persists, consult a professional mechanic.

To jump-start your Corolla, position another vehicle with a good battery close enough for the jumper cables to reach both batteries. Turn off both vehicles. Connect the red positive cable to the positive terminal of the dead battery, then to the positive terminal of the good battery. Connect the black negative cable to the negative terminal of the good battery, and attach the other end to an unpainted metal surface on the Corolla. Start the working vehicle, then the Corolla. Remove cables in reverse order.

Common causes include a loose gas cap, a faulty oxygen sensor, a malfunctioning catalytic converter, or an issue with the spark plugs. It's best to use an OBD-II scanner to read the error codes or consult a mechanic for a proper diagnosis.

To improve fuel efficiency, ensure tires are properly inflated, perform regular maintenance such as oil changes and air filter replacements, drive smoothly avoiding rapid acceleration, and reduce excess weight in the vehicle.

Spongy brakes could indicate air in the brake lines or low brake fluid. Check the brake fluid level and top it off if necessary. If the brake fluid is fine, the system may need to be bled. If unsure, consult a professional mechanic.
