When following a vehicle, Traffic-Aware Cruise Control remains active at low speeds, even when Model Y comes to a full stop. When the vehicle is moving again, Traffic- Aware Cruise Control resumes operating at the set speed. However, under the following circumstances, Traffic-Aware Cruise Control goes into a HOLD state, in which case, you need to briefly press the accelerator pedal to resume cruising. When the HOLD status is active, the instrument panel displays the HOLD icon and a message that indicates that you need to resume cruise control. The following circumstances can cause Traffic- Aware Cruise Control to go into the HOLD state:
Cruising Near or On Exits
When cruising near an exit on a controlled-access highway and engaging the turn signal toward the off- ramp, Traffic-Aware Cruise Control assumes you are exiting and begins to slow down Model Y. If you do not drive onto the off -ramp, Traffic-Aware Cruise Control resumes cruising at the set speed. In a region with right hand traffic, this occurs only when you engage the right turn signal when driving in the right-most lane within 164 feet (50 meters) of an exit. Likewise in regions with left hand traffic; when engaging the left turn signal when driving in the left-most lane within 164 feet (50 meters) of an exit.
When cruising onto an on-ramp to a controlled-access highway, Traffic-Aware Cruise Control automatically adjusts the set cruising speed to the speed limit of the highway, plus any off set you have specified.
NOTE: The on-board Global Positioning System (GPS) determines if you are driving in a region with right or left hand traffic. In situations where GPS data is unavailable (for example, if there is inadequate signal), engaging the turn signal near an exit does not cause Traffic-Aware Cruise Control to slow down Model Y.
When enabled while on a highway interchange or off- ramp, Traffic-Aware Cruise Control may reduce your set speed in 5 mph (5 km/h) increments - to as slow as 25 mph (40 km/h) - to better match the reported speeds of other Tesla vehicles that have driven at that specific location. To override this and continue cruising at your set speed, tap the accelerator pedal. The new set speed is maintained for the duration of the interchange or off -ramp (unless you override it or cancel Traffic- Aware Cruise Control). After the interchange or off- ramp, the set speed may revert or change as necessary based on the new location. For example, if you merged onto a different highway, the set cruising speed reverts back to what it was before driving on the interchange.
WARNING: In some cases (such as having insufficient data), Traffic-Aware Cruise Control may not automatically reduce the set speed on the highway interchange or off -ramp. Do not rely on Traffic-Aware Cruise Control to determine an appropriate driving speed. Tesla recommends driving at a speed that is safe for road conditions and within posted speed limits.
