Tesla offers an optional enhanced autopilot package which enables features like Traffic-Aware Cruise Control, Autosteer and Auto Lane Change. After completing the self-calibration process these feature can be activated.
To activate Traffic-Aware Cruise Control pull the cruise control lever towards you and release. You can adjust the cruising speed by moving the lever up and down. Once activated the gray speedometer icon turns blue and shows the set speed. The maximum speed is 90 mph (150 km/h) and the driver is responsible to recognize speed limits and be aware of road conditions. If you are driving on the right-most lane and engage the right turn signal within 164 feet (50 meters) of an exit Traffic-Aware Cruise Control slows down the vehicle. (In left hand traffic countries you need to be on the left-most lane and engage the left turn signal.)
Teslas autopilot features are currently in BETA status. Teslas autopilot is a level 2 autonomous driving system which requires the driver to stay alert, drive safely and be in control of the vehicle at all times. For current information on software updates please visit Tesla.com.
