While tempting for some, disabling Dyno Mode in your Tesla is crucial for safe and normal vehicle operation. Dyno Mode is a diagnostic tool designed for specific testing on a dynamometer, not for public road use. It significantly reduces or disables critical safety features like traction control, stability control, and automatic emergency braking, making your vehicle extremely unstable and dangerous to drive.
Understanding Tesla Dyno Mode: Why It's There, Why It's Dangerous ⚠️
Before we dive into disabling it, let's understand what Dyno Mode is and why it exists.

| How To Disable Dyno Mode Tesla |
What is Dyno Mode?
Tesla's Dyno Mode is a specialized diagnostic setting primarily intended for use on a chassis dynamometer (dyno). A dyno is a device used by engineers and performance testers to measure a car's power output at the wheels without the vehicle actually moving. To get accurate readings, a dyno test requires certain safety and stability systems to be temporarily deactivated, as these systems would otherwise interfere with the test by trying to correct for wheel spin when the car isn't moving.
The Dangers of Dyno Mode on Public Roads
When Dyno Mode is active, your Tesla's advanced safety features are compromised or completely turned off. This includes:
-
Traction Control (TC): This system prevents wheel spin by reducing power to slipping wheels and/or applying brakes. Without it, even slight acceleration can cause your tires to lose grip, especially in wet or low-traction conditions.
-
Stability Control (ESC/ESP): This system helps maintain vehicle stability during maneuvers by selectively applying brakes to individual wheels and/or reducing engine power to prevent skidding or loss of control. Without it, your Tesla can become incredibly difficult to handle, particularly in corners or during sudden evasive actions.
-
Automatic Emergency Braking (AEB): This vital safety feature automatically applies the brakes if it detects an imminent collision. Disabling it means your car won't intervene in a potential accident, putting you and others at extreme risk.
Driving with Dyno Mode enabled on public roads is highly irresponsible and dangerous. Many reports and videos exist of individuals losing control of their Teslas while in this mode, leading to accidents and serious safety concerns. Tesla itself issues warnings against using this mode on public roads. In some cases, Tesla has even limited the power output in Dyno Mode through software updates to deter unsafe use, making it less appealing for those seeking "performance enhancements" outside of its intended purpose.
Step-by-Step Guide: How to Disable Dyno Mode in Your Tesla
If you've somehow found yourself in Dyno Mode, or are unsure if it's active, here's how to ensure it's disabled and your Tesla is operating with all its safety features engaged.
Tip: Don’t skim — absorb.
Step 1: Acknowledge the Warning!
-
If your Tesla is in Dyno Mode, you'll likely see a prominent warning on your center touchscreen, possibly a red warning icon at the top, stating something like "Dyno Mode Enabled. Dev Mode Only – Do not drive on public roads."
-
Do not ignore this warning. Your car is actively telling you it's in an unsafe state for regular driving. Your first step is to pull over to a safe location immediately if you are currently driving.
Step 2: Access the "Power Off" Option
Tesla vehicles provide a straightforward way to deactivate Dyno Mode, usually by initiating a power cycle.
-
Locate the main "Car" or "Controls" icon on your Tesla's touchscreen (usually at the bottom or left side). Tap it to open the main controls menu.
-
Navigate to the "Safety & Security" tab. This tab contains various settings related to your vehicle's safety features and power options.
-
Within the "Safety & Security" tab, look for the "Power Off" button. This button is designed to shut down the vehicle's systems safely.
Step 3: Initiate the Power Off Sequence ↩️
-
Tap the "Power Off" button. Your Tesla will begin its shutdown sequence.
-
Important Note: Do NOT get out of the car or open a door immediately after tapping "Power Off." Allow the vehicle's systems to completely power down. You'll typically see the screen go dark and hear the systems quiet down. This process might take a minute or two.
Step 4: Re-Enter and Restart Your Tesla ✅
-
Once the car has fully powered down, wait for at least 30 seconds to a minute. This ensures all systems have reset.
-
Open the driver's door and then close it. This action often helps to "wake up" the car.
-
Press the brake pedal. This will typically power up your Tesla again.
-
Check your touchscreen. The "Dyno Mode" warning should now be gone, and all your safety features will be re-enabled. Your Tesla should now be back in its normal, safe operating mode.
Alternative Method: Exiting and Locking the Vehicle
In some cases, simply exiting the vehicle, locking it, and then returning and restarting it can also disable Dyno Mode.
-
Ensure the vehicle is in Park.
-
Exit the vehicle and close all doors.
-
Lock your Tesla using your phone app or key card/fob.
-
Wait for a few minutes (e.g., 5-10 minutes) for the vehicle to go into a deep sleep. This allows all systems to properly reset.
-
Unlock your Tesla and re-enter the vehicle.
-
Press the brake pedal to power it on.
This method effectively forces a full system reset, often resolving any persistent Dyno Mode activation.
Tip: Take mental snapshots of important details.

Dyno Mode vs. Track Mode: A Crucial Distinction ️
It's important not to confuse Dyno Mode with Track Mode, which is available on Performance variants of some Tesla models.
Track Mode
-
Purpose: Designed for closed-course driving and racetracks to enhance performance during spirited driving.
-
Features: While it does allow for more aggressive handling by adjusting stability and traction control, it does so in a sophisticated way that retains a degree of electronic assistance and cooling management tailored for track use. It also often provides real-time data and customizable settings.
-
Safety: Still intended for experienced drivers on a closed circuit. Tesla warns against using it on public roads.
Dyno Mode
-
Purpose: Strictly for dynamometer testing to measure power output.
-
Features: Completely disables crucial safety systems like traction control, stability control, and automatic emergency braking.
-
Safety: Extremely dangerous for public road use. It offers no performance benefit for regular driving and significantly increases the risk of losing control.
In essence, Track Mode is a performance-oriented driving mode with safety considerations for track use, whereas Dyno Mode is a raw diagnostic tool that strips away essential safety nets.
