With the touch of a button the Active Park Assist system uses an ultrasonic-based sensing system and Electric Power Assisted Steering (EPAS) to parallel park the vehicle without any assistance from the driver. There are sensors on the front and rear of the vehicle to help the system guide the vehicle into the driver's desired parking spot. Ford claims that its system is better than what is offered by Lexus since it requires less driver interface.
The Active Park Assist system will be available in mid-2009 on the Lincoln MKT and MKS. Ford hasn't stated what vehicles are next in line for the technology. Instead only mentioning that the system will be on 90 percent of Ford, Mercury and Lincoln vehicles by 2012.
