Ever wondered if your Tesla can make your highway drives even more relaxing? The answer is a resounding yes! Tesla's Traffic-Aware Cruise Control (TACC) is a game-changer, allowing your car to automatically adjust its speed to maintain a safe following distance from the vehicle ahead. It's not just a fancy gimmick; it's a feature designed for comfort and safety. Let's dive into how to master this incredible technology.
Step 1: Getting Familiar with Tesla's Autopilot System
Before we talk about cruise control, it's crucial to understand that TACC is a core part of Tesla's Autopilot suite. Autopilot encompasses several advanced driver-assistance systems (ADAS) that enhance your driving experience.

| How To Do Tesla Cruise Control |
1.1 What is Traffic-Aware Cruise Control (TACC)?
TACC is similar to traditional cruise control, but smarter. Instead of just maintaining a set speed, it also uses cameras and sensors to detect vehicles in front of you and automatically slow down or speed up to maintain a chosen following distance. Think of it as having an invisible co-pilot constantly managing your speed in traffic.
1.2 Differentiating TACC from Autosteer and Full Self-Driving (FSD)
It's important to distinguish TACC from other Autopilot features:
Autosteer: This feature works in conjunction with TACC to actively steer your Tesla within a clearly marked lane, helping to keep you centered. It's designed for highway use with clear lane markings.
Full Self-Driving (Supervised): This is Tesla's most advanced ADAS package, aiming to enable your car to drive to your destination with minimal driver intervention, handling things like navigating city streets, traffic lights, stop signs, and roundabouts. Even with FSD, active driver supervision is always required.
For the purpose of this guide, we'll primarily focus on the Traffic-Aware Cruise Control aspect.
Step 2: Preparing Your Tesla for TACC Engagement ⚙️
Before you can engage TACC, there are a few prerequisites and settings you might want to check or adjust.
2.1 Ensuring Camera Visibility and Calibration
Tesla's Autopilot system heavily relies on its cameras. Make sure your car's cameras (located around the vehicle) are clean and unobstructed. Dirt, ice, snow, or even heavy rain can impair their function. If your cameras haven't been calibrated, the system might prompt you to do so; this typically happens automatically by driving for a certain distance.
2.2 Understanding Autopilot Settings on Your Touchscreen
Navigate to the "Controls" menu on your Tesla's large touchscreen, then select "Autopilot." Here, you'll find important settings:
Set Speed: This allows you to choose how TACC engages. You can set it to engage at the currently detected speed limit or your current driving speed. Many drivers prefer "Current Speed" for immediate engagement at their present pace.
Offset: If you choose "Speed Limit" as your set speed, you can specify an offset (e.g., +5 mph) so the car cruises slightly above or below the detected limit.
Autopilot Activation: For some older models, you might have an "Autopilot Activation" setting. If you want to use TACC independently of Autosteer, ensure this is set to "Double Pull" (referring to the stalk). Newer models often simplify this, making TACC a single pull.
Tip: A slow skim is better than a rushed read.
Step 3: Engaging Traffic-Aware Cruise Control (TACC)
Now for the main event! Engaging TACC is quite straightforward, though the exact method can vary slightly depending on your Tesla model.
3.1 Engaging TACC in Model S/X (Older Models with Cruise Control Stalk)
For Model S and Model X vehicles equipped with a dedicated cruise control stalk on the left of the steering column:
While driving at your desired speed, pull the cruise control stalk down once.
Release the accelerator pedal. You'll hear a chime, and the cruising speed icon on your instrument cluster will turn blue to indicate TACC is active.
3.2 Engaging TACC in Model 3/Y (Newer Models with Gear Selector Stalk)
For Model 3 and Model Y vehicles, TACC is engaged using the right-hand gear selector stalk:
While driving at your desired speed, pull the gear selector stalk down once.
Release the accelerator pedal. A chime will sound, and the cruising speed icon on your display (usually to the right of the speedometer) will turn blue, confirming TACC is engaged.
3.3 What the Display Shows
When TACC is available but not engaged, you'll typically see a gray speed icon on your display. This number represents the speed that will be set when you engage TACC. Once engaged, this icon will turn blue and display your set cruising speed.
Step 4: Adjusting Speed and Following Distance
Once TACC is active, you'll want to fine-tune its behavior.
4.1 Changing Your Set Speed
You have a couple of ways to adjust your cruising speed:
Using the Scroll Wheel (Right Steering Wheel Scroll Button):
Roll the right scroll wheel up to increase the set speed.
Roll the right scroll wheel down to decrease the set speed.
A slow roll typically adjusts by 1 mph (or 1 km/h) increments, while a quick roll can jump to the closest 5 mph (or 5 km/h) increment.
Tapping the Speed Limit Sign (if applicable): On the touchscreen, if you're cruising at the speed limit, you can sometimes tap the speed limit sign to instantly adjust your set speed to the detected limit (including any offset you've set).
4.2 Adjusting the Following Distance
This is a critical aspect of TACC. Your Tesla will maintain a chosen distance from the vehicle in front of you. To adjust this:
QuickTip: A short pause boosts comprehension.
Roll the right scroll wheel left or right (depending on your model and software version) while TACC is engaged.
You'll see a visual representation of the following distance change on your display. A smaller number means a shorter following distance, while a larger number means a longer distance. Choose a distance that feels safe and comfortable for the current traffic conditions.
Step 5: Understanding TACC Behavior and Limitations
While TACC is a fantastic feature, it's not an autonomous driving system. You are always responsible for driving safely and staying attentive.
5.1 Automatic Acceleration and Deceleration
When no vehicle is detected ahead, your Tesla will maintain your set cruising speed.
When it detects a vehicle in front, it will automatically accelerate or decelerate to maintain your chosen following distance, up to your set speed.
It will also adjust speed when entering and exiting curves.
5.2 Temporary Overrides

You can manually accelerate at any time by pressing the accelerator pedal. Once you release the pedal, TACC will resume its set speed.
If you briefly hold the turn signal, your Tesla can accelerate to your set speed for overtaking, provided conditions are safe and TACC is operating.
5.3 "HOLD" State
Sometimes, especially in stop-and-go traffic, TACC might enter a "HOLD" state when at a complete stop. If this happens, you'll see a "HOLD" icon and a message on your display. To resume cruising, simply briefly press the accelerator pedal.
5.4 Important Limitations and Warnings:
Driver Responsibility: Always stay alert, keep your hands on the steering wheel, and be prepared to take immediate control. TACC is a convenience feature, not a substitute for attentive driving.
Environmental Conditions: TACC may not perform optimally in heavy rain, snow, fog, or icy conditions, or on winding roads with sharp curves.
Object Detection: It may not detect all objects, especially stationary ones or those partially in your lane, particularly at higher speeds.
Hills and Braking: TACC has limited braking capability, especially on steep downgrades, and might not always maintain the set speed perfectly. It can also sometimes brake unnecessarily due to false detections.
GPS Limitations: Be aware that your Tesla might slow down near exits or off-ramps due to GPS limitations, even if you don't intend to exit.
Step 6: Disengaging and Resuming TACC ↩️
Knowing how to disengage TACC is just as important as engaging it.
6.1 Canceling TACC
You can disengage Traffic-Aware Cruise Control in a few ways:
Press the brake pedal lightly. This is the most common and intuitive way.
Push the Autopilot stalk away from you once (for models with a stalk).
Push the gear selector stalk up once (for Model 3/Y).
Press the right scroll button on the steering wheel (for some models).
When TACC disengages, the blue cruising speed icon will turn gray or disappear, and a chime might sound. Your Tesla will then coast or use regenerative braking to slow down, similar to when you lift your foot off the accelerator.
Tip: Don’t overthink — just keep reading.
6.2 Resuming TACC
If TACC was recently active and you want to resume it at the previously set speed:
Move the Autopilot stalk up or down once and release (for models with a stalk).
Push the gear selector stalk down once (for Model 3/Y).
This will reactivate TACC at your last set speed, provided conditions allow.
Step 7: Practice and Patience Makes Perfect ✨
Like any new technology, getting comfortable with Tesla's Traffic-Aware Cruise Control takes a bit of practice. Start by using it on straight, open highways with light traffic. Gradually, as you gain confidence, you can experiment with it in slightly more complex scenarios.
Remember, the goal of TACC is to enhance your driving comfort and reduce fatigue, but it's never a substitute for your full attention and control. Enjoy the journey!
