Here is a concise summary of the 7 things you should never do in an automatic car:
1. **Don't shift gears while moving**: Can damage transmission and its components.
2. **Don't put the car in park before stopping**: Can cause irreversible damage to the transmission.
3. **Don't engage neutral when stopped at traffic lights**: Reduces control, wastes fuel, and can cause engine overheating.
4. **Don't put the car in neutral while going downhill**: Saves negligible fuel, reduces control, and can cause engine failure.
5. **Don't accelerate a stationary car in neutral**: Prematurely wears out belts and clutch in automatic transmissions.
6. **Don't leave the gas tank low regularly**: Can cause fuel pressure issues, wear out parts, and lead to costly repairs.
7. **Don't let water enter the transmission**: Can cause catastrophic damage, rust, and potentially require replacement.
Here are the key facts extracted from the text, numbered and in short sentences, excluding opinions:
**Automatic Car Facts**
1. Driving an automatic car seems easier than driving a manual car due to a simpler interface.
2. Automatic gearboxes are advantageous when climbing hills and in traffic jams.
3. Switching gears while the car is moving can damage the transmission and its components.
4. Replacing brakes costs around 640 reais, while repairing a damaged transmission can cost over 3,000 reais.
5. Newer car models use speed sensors to prevent shifting into park while moving.
6. Engaging the parking position (P) locks the transmission, preventing wheel movement.
7. Leaving the car in neutral at a traffic light can reduce control over the vehicle.
8. Modern automatic cars cut off fuel supply when going downhill, even in drive (D) gear.
9. Going downhill in neutral can reduce engine cooling and increase wear on engine components.
10. Accelerating from neutral can prematurely wear out belts and clutches in automatic transmissions.
11. Low fuel levels can cause increased wear on car parts due to reduced lubrication and fluid pressure.
12. Water in the transmission can cause significant damage, potentially requiring replacement.
13. Water in the transmission is absorbed by friction materials, causing damage that cannot be completely eliminated.
14. Rust can occur on metal transmission parts when water is present.
