To enable Intelligent Assist Steer :

1. Touch Controls > Assisted Driving > Intelligent Assist Steer .
2. After carefully reading and understanding the popup window, touch Yes.

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.

To indicate that Intelligent Assist Steer is available (but not actively steering Model 3), the top corner of the touchscreen displays a gray steering wheel icon next to the driving gear.

When a Intelligent Assist Steer is engaged and actively controlling Model 3, the steering wheel icon is blue.

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.

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 Intelligent Assist Lane Change 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, Intelligent Assist Lane Change 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.

To enable Intelligent Assist Navigate Driving , touch Controls > Assisted Driving > Intelligent Assist Navigate Driving . 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 .

The Intelligent Assist Navigate Driving icon shows in the turn-by-turn direction list when you are navigating to a destination and Intelligent Assist Navigate Driving is available but not active.

If Intelligent Assist Navigate Driving is active, the icon is blue. If Enable at Start of Every Trip is turned on, the Intelligent Assist Navigate Driving icon is selected whenever you start navigation. Touch the icon to cancel Intelligent Assist Navigate Driving and revert to 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.

Intelligent Assist Steer cancels when:

• You move the drive stalk upward

  

  CAUTION

  If you move the drive stalk upward and hold it up for more than one second, Model 3 shifts into Neutral after canceling Intelligent Assist Steer .
• 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.
• You exceed 140 km/h.
• You take over steering manually.
  Warning

  If Assisted Driving Activation is set to Double Pull and Intelligent Assist Steer cancels because you started steering manually, Traffic-Aware Cruise Control remains active. If Assisted Driving Activation is set to Single Pull 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.

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 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 normally (see Regenerative Braking).

When Intelligent Assist Steer is active and 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).

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), either:

• Push the drive stalk downward and briefly hold.
• Press the speed limit sign on the touchscreen.

It may take a few seconds for Model 3 to reach the new cruising speed.

Note

On a residential road, a road without a center divider, or a road that is not controlled access, the maximum allowed cruising speed is limited and the touchscreen displays a message. The restricted speed will be the speed limit of the road plus 10 km/h.

Adjusting the Following Distance

To adjust the following distance you want to maintain between Model 3 and a vehicle traveling ahead of you, press the steering wheel's right scroll button to the left or right.

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. Intelligent Assist Steer 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, Intelligent Assist Steer remains active at low speeds, even when Model 3 comes to a full stop. For example, Intelligent Assist Steer 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, Intelligent Assist Steer again accelerates up to the set speed.

Sometimes when Model 3 is at a full stop, Intelligent Assist Steer goes into a HOLD state. If this happens, briefly press the accelerator pedal to resume cruising.

When the HOLD status is active, the touchscreen displays the HOLD icon and a message that indicates that you need to resume cruise control.

Model 3 goes into HOLD state while Intelligent Assist Steer 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.

In situations where Assisted Driving is unable to steer Model 3, a warning chime sounds and the touchscreen displays the following message.

Take over immediately

When you see this message, take over steering immediately.

Intelligent Assist Steer requires driver attentiveness. Your hands must be on the steering wheel at all times while Intelligent Assist Steer is engaged, and you must monitor your surroundings, the road, and other road users.

Intelligent Assist Steer periodically displays a message reminding the driver to apply slight force to the steering wheel:

Apply slight turning force to steering wheel

Intelligent Assist Steer detects your hands by recognizing slight resistance as the steering wheel turns, or from you manually turning the steering wheel very lightly (without enough force to take over steering). Intelligent Assist Steer also qualifies your hands as being detected if you engage a turn signal use the Intelligent Assist Steer stalk, or use a button or scroll wheel on the steering wheel. If Model 3 does not detect slight turning force on the steering wheel, the touchscreen flashes and eventually chimes repeatedly. Do not use handheld devices while Intelligent Assist Steer is engaged.

If you repeatedly ignore prompts to apply slight force to the steering wheel or to pay attention, Intelligent Assist Steer disables for the rest of the drive and displays the following message requesting you to drive manually. If you don't resume manual steering, Intelligent Assist Steer sounds a continuous chime, turns on the warning flashers, and slows the vehicle to a complete stop.

Assisted Driving temporarily disabled Driver attention warnings ignored

Use of Assisted Driving features will be suspended if improper usage is detected.

Use of Intelligent Assist Steer is suspended for a week when you or another driver of your vehicle receives five "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 Controls > Assisted Driving .

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.
