How to maintain the fuel efficiency of my Toyota Highlander?

I have recently purchased a Toyota Highlander and I want to make sure I am taking the necessary steps to maintain its fuel efficiency. Can you give me some tips and advice on how to do so?

Regularly check and replace dirty air filters as they can reduce fuel efficiency.

Make sure to keep your tires properly inflated according to the recommended air pressure, as under-inflated tires can decrease fuel efficiency.

Try to avoid idling for long periods of time, as it wastes fuel.

Get your Toyota Highlander's engine tuned up regularly to maintain its fuel efficiency.

Use cruise control on the highway to maintain a consistent speed and save on fuel consumption.
