How It Works
Your Model S includes the following components that actively monitor the surrounding area:
- A camera is mounted above the rear license plate.
- Ultrasonic sensors (if equipped) are located in the front and rear bumpers.
- A camera is mounted in each door pillar.
- Three cameras are mounted to the windshield above the rear view mirror.
- A camera is mounted to each front fender.
- Radar is mounted behind the front bumper.
Model S is also equipped with high precision electronically-assisted braking and steering systems.
Active Safety Features
These Active Safety features, available on all vehicles that are equipped with the components shown above, are designed to increase your safety:
- Lane Assist (see Lane Assist)
- Collision Avoidance Assist (see Collision Avoidance Assist)
- Speed Assist (see Speed Assist)
You can enable/disable some of these features and in some cases, control how they work. To access settings for these features, touch.
These Autopilot convenience features are designed to reduce driver workload:
- Traffic-Aware Cruise Control (see Traffic-Aware Cruise Control)
- Autosteer (see Autosteer)
- Auto Lane Change (see Auto Lane Change)
- Autopark (see Autopark)
- Summon (see Summon)
- Smart Summon (Smart Summon)
- Stop Light and Stop Sign Warning (see Stop Light and Stop Sign Warning)
- Navigate on Autopilot (see Navigate on Autopilot)
- Traffic Light and Stop Sign Control (see Traffic Light and Stop Sign Control)
You can enable/disable some of these features and in some cases, control how they work. To access settings associated with these features, touch.
Drive to Calibrate Cameras
Model S must maneuver with precision when Autopilot features are being used. Therefore, before some features can be used for the first time or after some types of service repairs, cameras must complete a self-calibration process. For your convenience, the instrument panel displays a progress indicator.
When calibration is complete, Autopilot features are available for use. Calibration typically completes after driving 32-40 km, but the distance varies depending on road and environmental conditions. For example, calibration completes quicker when driving on a straight road with multiple lanes (such as a controlled-access highway), with highly-visible lane markings (in the driving lane as well as the adjacent lanes). Contact Tesla only if your Model S has not completed the calibration process after driving 160 km in the described conditions.
If a camera has shifted from its calibrated position (for example, the camera or windshield was replaced), you must clear the calibration. To do so, touch Model S repeats the calibration process. While this helps re-calibrate the cameras in many cases, Clear Calibration may not resolve all camera and sensor concerns.. When the calibration is cleared,
Many factors can impact the performance of Autopilot components, causing them to be unable to function as intended. These include (but are not limited to):
- Poor visibility (due to heavy rain, snow, fog, etc.).
- Bright light (due to oncoming headlights, direct sunlight, etc.).
- Damage or obstructions caused by mud, ice, snow, etc.
- Interference or obstruction by object(s) mounted onto the vehicle (such as a bike rack).
- Obstruction caused by applying excessive paint or adhesive products (such as wraps, stickers, rubber coating, etc.) onto the vehicle.
- Traffic signs that do not conform to standard recognizable formats, such as digital or temporary speed signs.
- Narrow or winding roads.
- A damaged or misaligned body panel.
- Use of gray or aftermarket glass.
- Interference from other equipment that generates ultrasonic waves.
- Extremely hot or cold temperatures.
Cleaning Cameras and Sensors
To ensure the various Autopilot components can provide information that is as accurate as possible, keep cameras and sensors (if equipped) clean and free of obstructions, condensation, or damage (see Cleaning).
Condensation can form inside the camera enclosures, especially if you park your vehicle outside in cold or wet conditions. The instrument cluster may display an alert stating that a camera is blocked and that some or all Autopilot features may be temporarily restricted until the camera vision is clear. To proactively dry the condensation, precondition the cabin by setting it to a warm temperature, turning the windshield defroster on, and directing the front air vents toward the door pillars (see Mobile App).
