The drain holes on the doors of the 2021 Corolla are located beneath the door panels. Generally, each door has at least two drain holes. However, due to their low position, these holes can easily become clogged when driving frequently on muddy roads. If water accumulates inside the door, it can erode the door panel, potentially damaging components such as the window regulator and audio system. Additional Information: 1. To ensure the proper functioning of the vehicle, different drain holes are designed for various functions to expel accumulated water. If these holes become blocked, water may backflow, corroding the body and electrical components or seeping into the cabin, affecting vehicle performance and safety. 2. Door leaks are typically caused by aging window seals or clogged door drain holes. This can lead to water seeping through the door trim and, in severe cases, pooling under the cabin carpet. Key drain holes on a car include those for the sunroof, doors, trunk, fuel filler cap, and front engine compartment. It is essential to clear these holes regularly during the rainy season. Sunroof leaks, commonly encountered, are often due to clogged sunroof drain holes, which can wet the roof lining or, in severe cases, flood water into the cabin.

What Causes the Engine Warning Light to Illuminate When the Car Is Not Started?

When the car is not started, the engine warning light is on because the vehicle is performing a self-check, indicating that the engine is not yet operational. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, creating expanding gases that push the pistons to perform work. Internal combustion engines typically transform chemical energy into mechanical energy. Methods for maintaining the engine include: 1. Regularly changing the oil and oil filter; 2. Using lubricants of appropriate quality grades; 3. Periodically cleaning the radiator; 4. Regularly replacing the air filter, oil filter, and fuel filter; 5. Ensuring good ventilation in the crankcase and cleaning it regularly; 6. Regularly cleaning the fuel system.

Should a car be driven frequently during the break-in period?

Whether to drive a car frequently during the break-in period depends on personal usage needs. The break-in period for a new car typically ranges between 3,000 to 5,000 km. Although new cars undergo initial break-in at the factory, the surfaces of components remain relatively rough. The break-in period significantly impacts the vehicle's future lifespan. Proper usage methods during the break-in period include: 1. Preheating the cold engine – reasonable warm-up allows the oil to lubricate the engine internals effectively, reducing wear; 2. Timely gear shifting while driving, especially for manual transmission vehicles – appropriate gear changes during break-in help avoid phenomena like high gear with low RPM or low gear with high RPM; 3. New vehicles require timely maintenance during the break-in phase.
