What are the essential maintenance tips for maximizing the fuel efficiency of a Toyota Prius?

I just bought a Toyota Prius and want to make sure I'm getting the best fuel efficiency possible. What are some tips for maintaining my car that will help me save on gas in the long run?

Regularly check your tire pressure and make sure they're properly inflated. Underinflated tires can decrease fuel efficiency by up to 3%.

Don't carry unnecessary weight in your car, as it can decrease your fuel efficiency. Clean out your trunk and only keep essentials.

Try to avoid rapid acceleration and braking, as it can significantly impact your fuel efficiency. Accelerate and decelerate gradually to save on gas.

Regularly change your air filter to improve air flow and save on gas. A dirty filter can decrease fuel efficiency by up to 10%.

Plan your trips and combine errands to reduce the amount of driving you do. The less you drive, the less gas you'll use.
