What is auto hold and does the rented vehicle have it?

Auto hold function holds the vehicle on a slope for easier start up. This function, if the mechanical/electrical handbrake is released, holds the brake for a couple of seconds while the driver is switching his leg  to the gas pedal, so the car would not go down the slope.  Most of the cars in our fleet are equipped with the mentioned function, however, on our web you can find the technical specifications and the equipment list that the rented vehicle has, as well as if it has the auto hold function or not.
