Oh, you're looking to add some humorous flair to your Tesla experience! You're in for a treat, as Tesla has a rather unique and amusing feature that allows your car to "fart" on demand. It's officially known as "Emissions Testing Mode" and is part of the Tesla Toybox. This guide will walk you through, step-by-step, on how to get your Tesla to release those digital toots right from your mobile app.
Step 1: Ensure Your Tesla and App are Ready to Rattle!
Before we dive into the nitty-gritty of making your Tesla emit some comical flatulence, let's make sure everything is in place. Think of this as preparing your stage for a grand performance of automotive humor!
1.1 Check Your Tesla's Software Version:
The "fart" feature, or "Emissions Testing Mode," was introduced quite a while ago as an Easter egg. However, it's always good to ensure your Tesla's software is up to date. Newer versions might have slight interface tweaks or expanded functionality.
To check, head to your Tesla's touchscreen and navigate to Controls > Software. Make sure you're running a relatively recent update.
1.2 Confirm Pedestrian Warning System (PWS) is Present:
For your Tesla to "fart" externally (which is where the real fun is!), your vehicle needs to be equipped with a Pedestrian Warning System (PWS). This is an external speaker designed to emit a low humming sound at low speeds for pedestrian safety, but Tesla, in its infinite wisdom, repurposed it for comedic effect.
Most Teslas manufactured after September 2019 are likely to have this. If your car was built earlier, you might need to check with a service center to see if it's retrofittable.
1.3 Verify Tesla Mobile App Installation and Connectivity:
This goes without saying, but you'll need the official Tesla mobile app installed on your smartphone (available for both iOS and Android).
Ensure your phone has a stable internet connection and that your Tesla is also connected to the internet (via Wi-Fi or cellular). This allows the app to communicate with your vehicle.
Log in to your Tesla account within the app.
Step 2: Locating the "Emissions Testing Mode" in Your App ️
Now that your setup is confirmed, let's pinpoint that glorious fart button within the Tesla app. This is where the magic begins!
2.1 Accessing the Live Camera Feed (The Sneaky Way):
Open the Tesla app on your smartphone.
On the home screen of the app, you might see quick control buttons. However, the most direct path to the fart function, especially for external farts, is often through the Live Camera feature.
If Sentry Mode is enabled on your vehicle, you can tap on "Live Camera" at the bottom of the app's home screen. This will give you a live view from your Tesla's external cameras.
Look closely at the bottom of the live camera interface. You should see a small, often unassuming, icon resembling a whoopie cushion. This is your target!
2.2 Alternative Access (If Available):
While the live camera is the primary method for remote app activation, some owners have reported being able to activate it by touching and holding any of the four quick control buttons on the app's home screen and then selecting the fart button from the pop-up menu. This might vary depending on your app version and vehicle software.
Step 3: Unleashing the Digital Detonation!
You've found the button! Now for the moment of truth. Prepare for giggles (and perhaps some confused stares from passersby).
3.1 Tapping for a Toot:
Once you've located the whoopie cushion icon within the Live Camera feed (or via the quick control buttons), simply tap on it.
Your Tesla, if equipped with the PWS and parked, will emit one of its pre-programmed fart sounds!
3.2 Customizing Your Cracks (In-Vehicle):
While the app provides remote activation, for a fuller experience and to choose which fart sound your Tesla makes, you'll need to be in the vehicle.
On your Tesla's touchscreen, go to the Application Launcher (the icon with three dots or a car icon, depending on your UI).
Tap on "Toybox".
Inside Toybox, you'll find the whoopie cushion icon representing "Emissions Testing Mode."
From here, you can:
Choose from a variety of fart sounds. Tesla has some amusing names like "Short Shorts Ripper," "Falcon Heavy," "Ludicrous Fart," "Neurastink," "Not a Fart," "Boring Fart," and "I'm So Random."
Select which seat the sound should emanate from (for internal farts).
Enable "Fart on demand" (activated by pressing the left scroll wheel button on the steering wheel) or "Fart using turn signal" (yes, your turn signal can make your car fart!).
3.3 Maximizing the Prank Potential:
For the ultimate effect with external farts, ensure your Tesla is parked outside.
Turn the volume up on your vehicle's audio system.
For an even more dramatic effect, consider rolling down your windows!
Important Note: Due to safety regulations, the Boombox feature (which includes the external fart sounds) is disabled while driving in many regions, including the US, Canada, and Puerto Rico. So, plan your pranks while stationary!
Frequently Asked Questions (FAQ)
How to access the fart mode on a Tesla?
To access fart mode (Emissions Testing Mode) on your Tesla's touchscreen, go to the Application Launcher (usually the icon with three dots or a car), then select "Toybox," and finally, tap the whoopie cushion icon.
How to make my Tesla fart from the mobile app?
To make your Tesla fart from the mobile app, open the Tesla app, tap on "Live Camera" (if Sentry Mode is enabled), and then tap the whoopie cushion icon at the bottom of the live camera feed. Alternatively, you might be able to long-press a quick control button and select it.
How to change the fart sounds in a Tesla?
You can change the fart sounds only from your Tesla's touchscreen. Go to "Toybox," select "Emissions Testing Mode," and then you'll see a list of different fart sounds to choose from.
How to make the Tesla fart externally?
To make the Tesla fart externally, your car needs the Pedestrian Warning System (PWS) speaker. Once you're in "Emissions Testing Mode" on the car's touchscreen or activate it via the app's Live Camera, the sound will be broadcast through the external speaker when the vehicle is parked.
How to ensure my Tesla has the Pedestrian Warning System (PWS)?
Most Teslas manufactured after September 2019 come with the PWS. You can typically verify this by checking if your car makes a low humming sound at low speeds (under 19 mph) when driving or in reverse, or by contacting Tesla service.
How to use the Tesla Boombox feature?
The fart mode is part of the Boombox feature. The Boombox allows your Tesla to play various sounds (including farts) externally through the PWS. You can also customize it with your own sounds via a USB drive.
How to schedule a fart for later in my Tesla?
Unfortunately, you cannot directly schedule a "fart" for a future time. The "Emissions Testing Mode" turns off automatically when the Tesla powers down, so you'll need to reactivate it manually when you want to deploy a sound.
How to troubleshoot if the fart mode isn't working?
Ensure your Tesla's software is up to date, the car is parked, and you have a stable internet connection for the app. If the external fart isn't working, verify your car has the PWS. For persistent issues, a simple reboot of the car's infotainment system (holding down both scroll wheels on the steering wheel) might help.
How to disable the fart mode?
To disable the fart mode, simply exit "Emissions Testing Mode" on your Tesla's touchscreen or don't activate it via the app. The feature doesn't stay enabled indefinitely.
How to use voice commands for fart mode?
For some vehicles, you can use voice commands to activate the fart feature. Try saying "Fart in their general direction" (a nod to Monty Python!). This typically works for the internal fart sounds.
