Many off road vehicle such as the new Toyota Rav 4 come with a system known as DAC or Downhill assist control, this form of system is available as standard on Automatic vehicles only.
This intelligent system allows for feet off driving on steep off-road descents when engine braking alone is not enough to slow down the car. This is where DAC comes in, it will electronically manage the vehicle’s brakes to ensure that exactly the right amount of hydraulic pressure is applied in order to prevent the wheels locking.
This will help in preventing the vehicle from slipping sideways to help keep it stable and of course steady, which will allow the driver to concentrate on the steering. This will not only make off road driving much safer, it will also make it much easier for drivers to tackle those tough off road enviroments and keep in complete control.
