How can I improve the fuel efficiency in my Volkswagen Touareg?

I recently bought a new Volkswagen Touareg and I noticed that it is quite fuel-consuming. Are there any tips or tricks to improve its fuel efficiency?

Regularly check your tire pressure to make sure they are inflated to the recommended level. Underinflated tires can decrease your fuel efficiency.

Avoid accelerating and braking aggressively. This can use up more fuel than necessary. Try to maintain a consistent speed while driving.

Consider using a fuel additive to help improve your engine's performance and increase fuel efficiency.
