To initiate Traffic-Aware Cruise Control when no vehicle is detected ahead of you, you must be driving at least 18 mph (30 km/h), unless certain vehicle and environmental conditions are met, in which case, you may be able to initiate it at lower speeds. If a vehicle is detected ahead of you, you can initiate Traffic-Aware Cruise Control at any speed, even when stationary, provided Model S is at least 5 feet (150 cm) behind the detected vehicle and certain vehicle and environmental conditions are met.
NOTE: The maximum cruising speed is 90 mph (150 km/h). It is the driver's responsibility to cruise at a safe speed based on road conditions and speed limits.
When Traffic-Aware Cruise Control is available but not engaged, the instrument panel displays the cruising speed in gray. The number shown represents the cruising speed that will be set when you engage Traffic-Aware Cruise Control.
When Traffic-Aware Cruise Control is actively cruising at a set cruising speed, the cruising speed is highlighted with blue text.
1. Touch Controls > Autopilot > Autosteer Activation and choose Double Click to allow you to use Traffic- Aware Cruise Control independently of Autosteer when you single press the right scroll wheel.
NOTE: If Autosteer Activation is set to single-click, pressing the right scroll wheel once also activates Autosteer (which includes Traffic-Aware Cruise Control).
2. You can choose whether Traffic-Aware Cruise Control engages at the currently detected speed limit or your current driving speed. Touch Controls > Autopilot > Set Speed and choose either Speed Limit or Current Speed. If you choose to engage Traffic-Aware Cruise Control at the currently detected speed limit, you can specify an off set. Touch Set Speed Off set. You can choose a Fixed off set, in which the cruising speed adjusts by a specific number of mph (km/h) on all roads, or a Percentage off set, in which the cruising speed is adjusted as a percentage of the road's detected speed limit.
WARNING: When cruising at the speed limit, there may be situations where the cruising speed may not change when the speed limit changes.
WARNING: Do not rely on Traffic-Aware Cruise Control or Speed Assist to determine an accurate or appropriate cruising speed. It is the driver's responsibility to cruise at a safe speed based on road conditions and applicable speed limits.
