Convenience

This intelligent cruise control system maintains a preset following distance behind another vehicle, automatically braking or accelerating as required.

Safety and Security

The vehicle is equipped with a system that senses, and then prepares, the vehicle and/or occupants, for an impending forward collision.
The vehicle constantly monitors the roadway in front of the vehicle and identifies and tracks pedestrians on an interior display. If the system determines a likely impact, it will automatically take preventative steps to avoid hitting the pedestrian.
The vehicle is equipped with a camera that displays an image of the area behind the vehicle on an interior display.
A head-up display projects gauge (speed, RPM, etc.) information onto the inside of the windshield just below the driver's line of sight.

Technology and Telematics

Apple CarPlay/Android Auto smart device wireless mirroring
Mobile devices can wirelessly connect to the internet through the vehicle's private mobile network.
