Avoid drifting out of your lane unintentionally. This is done using a camera that detects right and left lane markings.

Keep your vehicle at a safe distance behind others on the road with available Following Distance Indicator. Using forward-facing cameras and/or radar sensors, this feature monitors vehicles you're behind. When you're between .5 and 2.5 seconds away from another detected vehicle, the following time will be displayed.
With pulsing driver seat vibrations to communicate the direction of a possible crash threat, the available Safety Alert Seat works with the other available safety and driver assistance features using ultrasonic camera and/or radar sensors equipped on the vehicle to detect a possible collision situation. The Safety Alert Seat pulses on the left, right or both sides of the seat to alert you in the direction of the possible danger.
If a vehicle is approaching from the left or right when you're backing up, available Rear Cross Traffic Alert can signal you to a possible crash. When in reverse, sensors look for left or right cross traffic behind you. When detected, a red flashing triangle displays on the rear vision camera screen and points toward the approaching vehicle, along with audible beeps.
Park with ease when available Rear Park Assist is activated. Your rear speakers will emit repeated beeping sounds when your vehicle detects objects up to 8 feet behind you. The closer you move toward the object, the spacing between beeps will get shorter, helping you avoid the collision while you park your vehicle.
