Tesla's Cruise Control Systems
Yes, Tesla vehicles have cruise control, but Tesla calls it Autopilot and offers it in two versions depending on your model year and what you paid for. The basic version is Traffic-Aware Cruise Control, which works like traditional cruise control on other cars — you set a speed and the car maintains it. The more advanced version is Full Self-Driving (FSD) Capability, which adds steering control and other features on top of the cruise function.
The difference matters because they work differently and have different limitations. Traffic-Aware Cruise Control handles speed only; you still steer. Full Self-Driving can steer the car on highways and city streets, though you must keep your hands on the wheel and stay alert. Neither one drives the car without you.
Key Takeaways
- All Teslas come with Traffic-Aware Cruise Control, which maintains your set speed and slows for traffic ahead, similar to cruise control in other cars.
- Full Self-Driving is an optional paid upgrade that adds steering control and other features, but requires you to keep your hands on the wheel and watch the road at all times.
- You set up cruise control by pulling the stalk toward you once (Traffic-Aware) or twice (Full Self-Driving) while driving on a highway or suitable road.
- The system uses cameras and radar to detect traffic, pedestrians, and road markings, and will disengage if it detects you are not paying attention.
How to Turn On Traffic-Aware Cruise Control
To use the basic cruise control in a Tesla, you pull the cruise control stalk (the lever on the right side of the steering column) toward you once. The car will begin maintaining whatever speed you are currently driving. You can then adjust the speed up or down using the scroll wheel on the stalk — scroll up to increase speed, scroll down to decrease it.
The system will automatically slow down if it detects a car ahead of you, and speed back up when that car moves out of the way. This is why Tesla calls it "Traffic-Aware" — it is not just holding a fixed speed like older cruise control. If you want to cancel it, push the stalk away from you or press the brake pedal.
Full Self-Driving and What It Actually Does
Full Self-Driving is a paid subscription or one-time purchase that adds steering control on top of cruise control. When you pull the stalk toward you twice (or hold it), the car will steer itself on highways and, depending on your software version, on city streets with traffic lights and stop signs. It will change lanes, navigate intersections, and handle turns.
The critical thing to understand: you must keep your hands on the wheel. The car monitors whether you are touching the steering wheel and will give you warnings if you are not. If you ignore the warnings, the system will disengage. This is not a self-driving car in the sense that you can take a nap — it is an advanced driver information system that requires your constant attention and willingness to take over when ready if something goes wrong.
Full Self-Driving is not included in the base price of a Tesla. You either pay for it upfront when you buy the car, or you can subscribe to it monthly through the Tesla app. The monthly cost varies by region and changes over time.
What Sensors and Cameras Make This Work
Tesla's cruise control systems rely on eight cameras mounted around the car, radar, and ultrasonic sensors. The cameras watch the road ahead, the lanes on either side, and behind the car. The radar looks through rain, fog, and darkness to detect other vehicles. Together, these sensors let the car see traffic, pedestrians, lane markings, and obstacles.
The car's computer processes this information many times per second and decides whether to speed up, slow down, steer, or change lanes. If the sensors fail or become obstructed — for example, if a camera is covered with mud or snow — the system may not work or may disengage without warning. This is why Tesla recommends keeping cameras and sensors clean.
When Cruise Control Will Not Work
Traffic-Aware Cruise Control and Full Self-Driving only work on roads where the car can see lane markings or detect the road structure clearly. They do not work on local streets without clear markings, in parking lots, or on roads where visibility is very poor. The system also requires that you are actively driving — you cannot engage it while parked or at very low speeds.
In heavy rain, snow, or fog, the system may not work as well or may disengage because the cameras cannot see the road clearly enough. Similarly, if the car detects that you are not paying attention — by monitoring whether your hands are on the wheel or your eyes are on the road — it will turn off the system and alert you to take control.
Cruise Control Versus Full Self-Driving: Which One Do You Get
Every Tesla comes with Traffic-Aware Cruise Control included in the base price. You do not pay extra for this. Full Self-Driving is optional and costs extra — either as a one-time purchase or a monthly subscription. If you are not sure whether your Tesla has Full Self-Driving, you can check by opening the Controls menu on your touchscreen and looking for the Autopilot section. If you see "Full Self-Driving" listed, you have it. If you only see "Traffic-Aware Cruise Control," you have the basic version.
Many owners use Traffic-Aware Cruise Control on long highway drives and never buy Full Self-Driving. Others subscribe to Full Self-Driving for city driving or highway use. The choice depends on your budget and how much automation you want.
Safety Reminders and Limitations
Both systems require you to stay alert and ready to take control. Tesla's own documentation is clear: these are driver information features, not self-driving features. You are responsible for the car at all times. The system can fail, misread the road, or encounter a situation it was not trained to handle. If you are tired, distracted, or impaired, do not use cruise control.
The National Highway Traffic Safety Administration (NHTSA) has investigated Tesla's Autopilot system multiple times. Some investigations have found that the system can be engaged in situations where it should not be, or that it does not always detect obstacles. If you use these features, understand their limitations and treat them as tools that help you drive, not replacements for your attention.
Frequently Asked Questions
Can I use cruise control on city streets or just highways?
Traffic-Aware Cruise Control works on any road where the car can see lane markings clearly — highways, rural roads, and some city streets. Full Self-Driving can navigate city streets with traffic lights and stop signs, but only if your software version supports it and the road is clear enough for the cameras to see. Local streets without clear markings usually will not work.
What happens if I fall asleep while cruise control is on?
The system will detect that you are not touching the wheel and will alert you with warnings and sounds. If you do not respond, it will disengage and slow the car down. It will not keep driving — you must be awake and attentive. Never rely on cruise control as a substitute for rest.
Does cruise control work in rain or snow?
Traffic-Aware Cruise Control usually works in light rain, but heavy rain, snow, or fog can degrade the cameras' ability to see the road. The system may not work as well or may turn off without warning. In severe weather, it is safer to drive manually.
Can I upgrade from Traffic-Aware Cruise Control to Full Self-Driving later?
Yes. You can purchase Full Self-Driving at any time through your Tesla app or account. The cost may be different from what it was when you bought the car, as Tesla adjusts pricing. You can also cancel a subscription at any time.
Is Full Self-Driving the same as a fully autonomous car?
No. Full Self-Driving still requires you to keep your hands on the wheel and watch the road. You must be ready to take over when ready. It is an advanced driver information system, not a fully self-driving vehicle. You are always responsible for the car.
