Assisted Driving Features
- Traffic-Aware Cruise Control : Like traditional cruise control, Traffic-Aware Cruise Control maintains a set driving speed. However, Traffic-Aware Cruise Control also slows down or accelerates Model 3 as needed to maintain the following distance from the vehicle in front of you. While Traffic-Aware Cruise Control is engaged, you are still responsible for steering Model 3 (see Traffic-Aware Cruise Control).
- Intelligent Assist Steer : Like Traffic-Aware Cruise Control, Intelligent Assist Steer maintains a set speed (if there is not a vehicle in front of you) or a set following distance (if there is a vehicle in front of you). In addition, Intelligent Assist Steer detects lane markings, road edges, and the presence of vehicles and objects to intelligently keep Model 3 in its driving lane (see Intelligent Assist Steer).
- Intelligent Assist Lane Change : When you engage a turn signal while Intelligent Assist Steer is active, Intelligent Assist Lane Change moves Model 3 into the adjacent lane in the direction indicated by the turn signal (see Intelligent Assist Lane Change).
- Intelligent Assist Navigate Driving : Intelligent Assist Navigate Driving builds on the features of Traffic-Aware Cruise Control and Intelligent Assist Steer . While Intelligent Assist Steer is active, Intelligent Assist Navigate Driving allows Model 3 to suggest and, if configured, automatically change lanes to pass other vehicles and follow the navigation route (see Intelligent Assist Navigate Driving).
Assisted Driving Settings
- Set Speed: Choose whether Assisted Driving engages at the currently detected speed limit or your current driving speed. Touch and choose either Speed Limit or Current Speed.
- Offset: If you choose Speed Limit, you can specify an offset by touching Set Speed Offset. You can choose Fixed (the cruising speed adjusts by a specific amount on all roads) or Percentage (the cruising speed is adjusted as a percentage of the road's detected speed limit).

When you engage Intelligent Assist Steer , Model 3 confirms activation with an audible chime and briefly displays a message on the touchscreen reminding you to pay attention to the road and be ready to take over at any time.
When Intelligent Assist Steer is able to detect lane markings, it displays the edges of the driving lane in blue on the touchscreen.
Whenever Intelligent Assist Steer is active, Traffic-Aware Cruise Control is active as well.
In situations where the speed limit cannot be detected when Intelligent Assist Steer is engaged, Intelligent Assist Steer reduces your driving speed and limits the set cruising speed to 70 km/h. Although you can manually accelerate to exceed the limited speed, Model 3 will not brake for detected obstacles as long as you are applying the accelerator pedal. Intelligent Assist Steer slows down to the limited speed when you release the accelerator pedal. When you leave the road or disengage Intelligent Assist Steer by using the steering wheel, you can increase your set speed again, if desired.
Intelligent Assist Lane Change
If you engage a turn signal while Intelligent Assist Steer is active, Model 3 moves into the adjacent lane in the direction indicated by the turn signal, provided the following conditions are met:
- The turn signal is engaged.
- Lane markings indicate that a lane change is permitted.
- Midway through the lane change, Model 3 must detect the target lane's outside lane marking. If this lane marking is not detected, the lane change is aborted and Model 3 returns to its original driving lane.
- The view of the camera(s) is not obstructed.
- Model 3 does not detect a vehicle in its blind spot, or a vehicle or obstacle up to the center of the target lane. If a vehicle or other obstacle is detected in the target lane, it is shown in red in the visualization on the touchscreen and Model 3 does not complete the lane change until it is safe to do so.
The minimum speed at which Assisted Driving changes lanes may vary depending on region, adjacent lane speeds, and other factors. Always be ready to manually steer and change lanes as necessary. When an automatic lane change is in progress, Overtake Acceleration is activated, allowing Model 3 to accelerate closer to a vehicle in front (see Overtake Acceleration).
When you engage a turn signal, Assisted Driving moves Model 3 one lane at a time. Moving into an additional lane requires you to engage the turn signal a second time after the first lane change is complete.
As Model 3 changes lanes, it is important to monitor its performance by watching the driving path in front of you and the surrounding area. Stay prepared to take over steering at any time. As you are crossing over into the adjacent lane, the touchscreen displays the location in the lane that Model 3 is moving into.
Intelligent Assist Navigate Driving
To enable Intelligent Assist Navigate Driving , touch . Then, to customize how you want Intelligent Assist Navigate Driving to operate, touch Customize Intelligent Assist Navigate Driving :
- Enable at Start of Every Trip: Choose whether to automatically enable Intelligent Assist Navigate Driving for every navigation route. When enabled, the Intelligent Assist Navigate Driving button on the turn-by-turn direction list is already enabled at the start of every trip.
- Speed Based Lane Changes: Intelligent Assist Navigate Driving is designed to perform both route-based and speed-based lane changes. Speed-based lanes changes are optional. You can use this setting to disable speed-based lane changes or to specify how assertively you want Intelligent Assist Navigate Driving to change lanes to achieve the set cruising speed (Mild, Average, or Mad Max).
- Exit Passing Lane: Choose whether you want Intelligent Assist Navigate Driving to maneuver out of a passing lane when navigating to a destination. In addition to route-based and speed-based lane changes, Intelligent Assist Navigate Driving requests a lane change out of a passing lane as a reminder to stay in a slower lane when you are not passing other vehicles. Choose No to disable this and keep Model 3 in a passing lane except when needed to stay on the navigation route.
- Require Lane Change Confirmation: (if equipped) By default, Intelligent Assist Navigate Driving requires your confirmation before proceeding with a lane change by engaging the appropriate turn signal. If you do not confirm the lane change within 3 seconds, a chime sounds to remind you that Intelligent Assist Navigate Driving requires your confirmation to change lanes.
- Lane Change Notification: You can specify if or how you want to be notified of lane changes (Off, Chime, Vibrate, or Both).
If Enable at Start of Every Trip is turned on, Intelligent Assist Navigate Driving engages automatically when:
- Intelligent Assist Steer is active.
- You are navigating to a destination.
- You are on a controlled-access highway.
Once enabled, the Intelligent Assist Navigate Driving button appears on the map’s turn-by-turn direction list whenever a navigation route is active and the route includes at least one controlled-access highway.
If Enable at Start of Every Trip is turned off, touch the Intelligent Assist Navigate Driving button above the turn-by-turn directions to enable it. Once the Intelligent Assist Navigate Driving is selected, it will engage whenever you engage Intelligent Assist Steer .
Whenever Intelligent Assist Navigate Driving is active, the Intelligent Assist Navigate Driving button is blue and the touchscreen displays the driving lane as a single blue line in front of Model 3:
The turn-by-turn directions display the Intelligent Assist Steer icon next to the maneuvers (such as off-ramps) that Intelligent Assist Navigate Driving will handle.
When Intelligent Assist Navigate Driving is engaged Model 3 automatically makes both speed-based and route-based lane changes.
- Speed Based Lane Changes: Intelligent Assist Navigate Driving changes lanes to reduce driving time to your destination. For example, if Model 3 is behind a vehicle going below the set cruising speed, Intelligent Assist Navigate Driving will move into the passing lane to pass it. Speed-based lanes changes are optional.
- Route Based Lane Changes: Intelligent Assist Navigate Driving changes lanes to route you to your destination. For example, Intelligent Assist Navigate Driving will move into the exit lane as Model 3 approaches the off-ramp specified by the navigation route.
If you ignore a route-based lane change suggestion (for example, you are driving in the left lane while approaching an off-ramp on the right side of the highway), Intelligent Assist Navigate Driving is unable to maneuver onto the off-ramp and as a result, you are re-routed to your destination.
Intelligent Assist Navigate Driving activates and deactivates based on the type of road you are driving on. When Intelligent Assist Navigate Driving is active and you approach an off-ramp or interchange along your navigation route, the appropriate turn signal engages and Intelligent Assist Steer maneuvers Model 3 onto the off-ramp or interchange.
When you leave a controlled-access highway Intelligent Assist Navigate Driving reverts to Intelligent Assist Steer —a chime sounds and the touchscreen displays the driving lane lines in blue (instead of the single blue in front of Model 3). When Intelligent Assist Navigate Driving deactivates, Intelligent Assist Steer remains active. Always be prepared to take appropriate action.
Canceling Assisted Driving
Traffic-Aware Cruise Control cancels when:
- You press the right scroll button on the steering wheel.
- You press the brake pedal.
- You exceed 140 km/h.
- You shift into Reverse, Park, or Neutral.
- A door is opened.
- An Automatic Emergency Braking event occurs (see Collision Avoidance Assist).
- The driver's seatbelt is released, and/or the driver gets out of their seat.
When Traffic-Aware Cruise Control cancels, the cruising speed icon on the touchscreen turns gray to indicate that Traffic-Aware Cruise Control is no longer active.
- You exceed 140 km/h.
- You take over steering
manually.WarningIf Assisted Driving Activation is set to Double Click and Intelligent Assist Steer cancels because you started steering manually, Traffic-Aware Cruise Control remains active. If Assisted Driving Activation is set to Single Click and Intelligent Assist Steer cancels because you started steering manually, Traffic-Aware Cruise Control also cancels.
- You do not respond to repeated reminders to keep your hands on the wheel and subsequent messages on the touchscreen .
When Intelligent Assist Steer cancels, a chime sounds and the Intelligent Assist Steer icon either turns gray to indicate that Intelligent Assist Steer is no longer active, or disappears to indicate that it is not currently available.
- You touch the Intelligent Assist Navigate Driving button on the map’s turn-by-turn direction list. In this case, Intelligent Assist Steer is still active.
- You leave a controlled-access highway. When this happens, Intelligent Assist Steer is still active.
When Intelligent Assist Navigate Driving cancels but Intelligent Assist Steer remains active, a chime sounds and the visualization goes from a single blue line in the driving lane to two blue lines on either side of the lane.
When Traffic-Aware Cruise Controlor Intelligent Assist Steer cancels, Model 3 does not coast. Instead, regenerative braking slows down Model 3 in the same way as when you move your foot off the accelerator when driving without Traffic-Aware Cruise Control (see Regenerative Braking).
While Using Assisted Driving
When Traffic-Aware Cruise Control is active and Assisted Driving is maintaining a set speed, the speed is highlighted with blue text on the touchscreen.
When Intelligent Assist Steer is active, the steering wheel icon is blue and the lane markings are highlighted in blue on the visualization. If Intelligent Assist Navigate Driving is also active, the Intelligent Assist Navigate Driving button is blue and the touchscreen displays the driving lane as a single blue line in front of Model 3.
If unable to detect lane markings, Intelligent Assist Steer may determine the driving lane based on a vehicle you are following. In most cases, Intelligent Assist Steer attempts to center Model 3 in the driving lane. However, there may be situations in which Intelligent Assist Steer follows a driving path that is offset from the center of the lane (for example, if guard rails are detected).
Maintaining the Set Speed
When Assisted Driving is active, Model 3 maintains your set cruising speed whenever a vehicle is not detected in front of it. When cruising behind a vehicle, Model 3 accelerates and decelerates as needed to maintain a chosen following distance (see Adjusting the Following Distance), up to the set speed.
You can manually accelerate at any time by pressing the accelerator pedal, but when you release the pedal Model 3 resumes cruising at the set speed.
Model 3 also adjusts the cruising speed when entering and exiting curves.
When Model 3 is actively slowing down to maintain the selected distance from the vehicle ahead, brake lights turn on. You may notice slight movement of the brake pedal. However, when Model 3 is accelerating, the accelerator pedal does not move.
Changing the Set Speed
Roll the right scroll wheel up to increase, or down to decrease, the set speed.
To change the cruising speed to the current speed limit (including any offset you've specified), press the speed limit sign on the touchscreen.
It may take a few seconds for Model 3 to reach the new cruising speed.
Adjusting the Following Distance
The closest following distance is 2.
Each setting corresponds to a time-based distance that represents how long it takes for Model 3, from its current location, to reach the location of the rear bumper of the vehicle ahead of you. Assisted Driving retains your setting until you change it again.
As you adjust the following distance, the touchscreen displays the current setting.
Stopping and Slowdowns
When moving significantly faster than vehicles in adjacent lanes, Model 3 automatically reduces the driving speed. This is especially helpful in heavy traffic situations or when vehicles are constantly merging into different lanes. When Model 3 detects other vehicles driving significantly slower, the touchscreen highlights the adjacent lanes with arrows and detected vehicles in gray, and Model 3 reduces the driving speed as appropriate. To temporarily override this feature, press the accelerator pedal.
When following a vehicle, Assisted Driving remains active at low speeds, even when Model 3 comes to a full stop. For example, Assisted Driving remains active even if Model 3 slows down to a complete or near-complete stop in heavy, stop-and-go traffic on a highway. When traffic starts moving more rapidly, Assisted Driving again accelerates up to the set speed.
Sometimes when Model 3 is at a full stop, Assisted Driving goes into a HOLD state. If this happens, briefly press the accelerator pedal to resume cruising.
Model 3 goes into HOLD state while Assisted Driving is active in the following circumstances:
- Model 3 has been at a standstill for 5 minutes.
- Model 3 detects a pedestrian (the HOLD state may clear when the pedestrian is no longer detected).
- Model 3 suddenly loses visibility of the vehicle in front of you.
- An obstacle is detected in front of Model 3.
Cruising Near or On Exits
When you are cruising near an exit on a controlled-access highway and engage the turn signal toward the off-ramp, Assisted Driving assumes you are exiting and begins to slow down Model 3. If you do not drive onto the off-ramp, Assisted Driving 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 50 meters of an exit. Likewise in regions with left hand traffic, this occurs when engaging the left turn signal when driving in the left-most lane within 50 meters of an exit.
When cruising onto an on-ramp to a controlled-access highway, Assisted Driving automatically adjusts the set cruising speed to the speed limit of the highway, plus any offset you have specified. If Intelligent Assist Navigate Driving is engaged, it disengages as you leave the controlled-access highway (see Canceling Assisted Driving). In this case, Intelligent Assist Steer remains active.
Overtake Acceleration
Engage the turn signal momentarily to accelerate Model 3 towards the vehicle ahead of it. By momentarily holding the turn signal, you can quickly accelerate up to your set speed without having to press the accelerator pedal as long as:
- Traffic-Aware Cruise Control is operating and detects a vehicle in front of you.
- No obstacles or vehicles are detected in the target lane.
- Model 3 is traveling below the set speed, but over 72 km/h.
Model 3 stops accelerating when you reach your set cruising speed, if changing lanes takes too long, or if Model 3 gets too close the vehicle ahead. Model 3 also stops accelerating if you disengage the turn signal.
Take Over Immediately
In situations where Assisted Driving is unable to steer Model 3, a warning chime sounds and the touchscreen displays the following message.
When you see this message, take over steering immediately.
Driver Attentiveness
Assisted Driving features require that the driver pay attention to the road, their surroundings, and other road users.
The cabin camera monitors continued driver attentiveness when Assisted Driving is engaged. This system cannot be disabled. The cabin camera does not require full visibility of the driver's eyes in order to monitor attentiveness. The system is still active, for example, if the driver is wearing sunglasses.
If the cabin camera does not have clear visibility of the driver's hand and arm locations, the touchscreen periodically displays a message reminding the driver to apply slight force to the steering wheel.
If the driver repeatedly looks away from the road, the touchscreen displays a warning. The warning is dismissed once the driver begins paying attention to the road again.
If the driver repeatedly ignore prompts to apply slight force to the steering wheel or to pay attention, Assisted Driving displays a series of escalating warnings and, if those warnings are ignored, disables for the rest of the drive and displays the following message.
If the driver does not resume manual steering, Model 3 sounds a continuous chime, turns on the warning flashers, and slows to a complete stop.
Assisted Driving Suspension
Use of Assisted Driving features will be suspended if improper usage is detected.
Use of Intelligent Assist Steer and Intelligent Assisted Driving is suspended for a week when you or another driver of your vehicle receives five Assisted Driving "strikeouts." A strikeout is when the Assisted Driving system disengages for the remainder of a trip after the driver receives several audio and visual warnings for inattentiveness.
You can see how many strikeouts are remaining before Assisted Driving access is suspended by touching .
A strikeout is forgiven after half a week (3.5 days), as long as you don't receive another strikeout in that time.
There may be occasions where driver intervention is required and you must take over immediately to maintain safe driving. Driver-initiated disengagements do not count as improper usage and are expected from the driver.
