NOTE1:Don't use it for to long or your motor will overheat and capture fireplace, and if you put on't maintenance the engine with the Ur button your racing pod WILL explode. When it will be full, release the A button and rapidly press and keep the A new button once again to get a increase. (Make certain you have the A new button kept down) If the meter has a green light in the group, keep the analog stay up to create the bar meter rise from the base.
While race, If you look at the bottom level right hand part, there is definitely a meter.
