Objects use more energy when increasing in speed or starting while objects use less energy while going at a steady pace.
When a moving car slows down, its kinetic energy decreases because kinetic energy is directly related to an object's speed. As the car decelerates, its speed decreases, causing its kinetic energy to decrease as well. This energy is ultimately transferred into other forms, such as heat generated by the brakes.
Basically, in physics, total energy is always conserved. Of course, it is possible for some of the energy from a car to go somewhere else.
"Brakes" make the whole car slow down.
Generally speaking for cars that have "disk brakes", friction slows the car. When the driver presses down on the brake pedal the brake calipers squeeze the brake pads against the brake rotor inside each car wheel causing the car to slow down by friction.
converting kinetic energy into thermal energy through friction in the brakes, resulting in a decrease in speed.
The engine doesn't have to use as much fuel when the car is traveling downhill.

When the car has no gas, no energy is used and no energy is produced.

Most of the mechanical (or kinetic) energy is converted to heat.

Yes. Acceleration is any change in velocity. When a car slows down it is decelerating; think of deceleration as acceleration in the negative direction.
A car goes faster when you accelerate. It slows down when you brake.
When a car slows down
The car is losing kinetic energy as it climbs the hill. This kinetic energy is being transferred into potential energy due to the increasing height gained during the climb.
