How to optimize fuel economy in a BMW X5?

I have noticed that my BMW X5 consumes a lot of fuel. What steps can I take to improve the fuel economy and save money on gas?

Check your tire pressure regularly as under-inflated tires can increase fuel consumption. Keep them at the recommended pressure level for your vehicle.

Avoid aggressive driving and quick acceleration. This not only puts unnecessary strain on your car's engine, but also burns more fuel.

Try to avoid idling for long periods of time. If you're going to be stopped for more than a minute, it's better to turn off your engine and restart it when you're ready to move again.
