The pre-collision system in your Toyota Camry can save your life, but it sometimes triggers when you do not want it to. A false alarm might brake your car hard for no reason on a clear road. This guide shows you exactly how to disable the pre-collision system quickly using a built-in dashboard shortcut.
Quick Answer
To disable the pre-collision system in a Toyota Camry, stop your car completely. Press and hold the traction control button (the car icon with squiggly lines) for three seconds. The system will turn off, but it automatically turns back on the next time you start the engine.
Key Takeaways
- You must bring your Camry to a complete stop before turning off the system.
- Hold the traction control button for three seconds to completely disable the alerts.
- The pre-collision system turns back on every time you restart the car.
- You can adjust the system sensitivity in the dashboard menu instead of turning it off completely.
What Is the Pre-Collision System in a Toyota Camry?
Toyota includes the pre-collision system to keep you safe on the road. According to Toyota, the system uses radar and cameras to detect other cars and pedestrians. If it senses an imminent crash, it sounds a warning and applies the brakes. Toyota has included this system on most models for over eight years.
While the system protects you, navigating the dashboard settings takes time. The system resets to active every time you start the car. Knowing how to manage these settings gives you better control over your driving experience.
Step-by-Step: How to Disable the Pre-Collision System
Before You Begin
Time required: 1 minute
You do not need any special tools. Ensure you park your car on a flat surface in a safe location. You cannot disable the system while the vehicle moves.
Step 1: Locate the Traction Control Button
Find the traction control button near your gear shift on the center console. The button displays a picture of a car with two squiggly lines underneath the tires.
Step 2: Press and Hold the Button
Bring your Camry to a complete stop. Press and hold the traction control button for exactly three seconds. A message or a yellow warning light will appear on your dashboard. This visual cue confirms you turned off the pre-collision system.
Troubleshooting Common Mistakes
If the system does not turn off, check your speed. The shortcut only works when the car sits at a dead stop. If you only press the button once quickly, you disable traction control, but the pre-collision system remains active.
Risks of Turning Off the Pre-Collision System
Warning: Turning off this system disables automatic emergency braking, which greatly increases your risk of a forward crash.
Think carefully before you use this shortcut. The system spots hazards you might miss, especially pedestrians in low light. Without it, you lose critical emergency braking. Use this bypass only when absolutely necessary, such as driving through an automated car wash or dealing with a broken sensor.
Limitations of the Deactivation Shortcut
Toyota designed this shortcut strictly as a temporary bypass. You cannot permanently disable the system using this button. If you experience frequent false alarms, disabling the system on every single trip becomes a major inconvenience.
What Happens When You Restart Your Car?
When you turn off your engine, the car resets its internal computer. The next time you start the car, the pre-collision system turns back on automatically.
Toyota builds the system this way to ensure you always have safety features active by default. If you want the system off for your next drive, you must stop the car and hold the traction control button for three seconds again.
How to Adjust Pre-Collision Sensitivity
If the automatic brakes trigger too often, you do not have to turn the system off entirely. You can lower the sensitivity directly through your steering wheel controls.
Use the arrows on your steering wheel to open the settings menu on your dashboard screen. Find the gear icon and select the Pre-Collision System (PCS). From there, you can choose between early, medium, and late warning timing. Setting it to “late” stops the car from braking too early in normal traffic. Consult your owner’s manual for specific instructions regarding your model year.
Frequently Asked Questions
Can I permanently disable the pre-collision system?
No, Toyota does not allow you to permanently disable the pre-collision system. It resets to the active state every time you start the car’s engine to meet modern safety regulations.
Where is the pre-collision sensor located on a Camry?
The main radar sensor sits directly behind the front grille, usually integrated into the Toyota emblem. A secondary camera sits behind your rearview mirror near the top of the windshield.
Why does my pre-collision system brake for no reason?
Dirt, heavy rain, or thick snow can block the sensors and cause false alarms. If the sensor thinks an object is too close, it applies the brakes. Keep the front emblem and upper windshield clean to prevent this issue.
Does turning off traction control turn off the pre-collision system?
A quick tap of the button only turns off the traction control system. You must hold the button down for three full seconds to disable both traction control and the pre-collision system simultaneously.

Conclusion
You can easily turn off the pre-collision system in your Toyota Camry by holding the traction control button for three seconds while completely stopped. This shortcut provides quick control when a blocked sensor causes unwanted braking. For everyday driving, try lowering the system’s sensitivity in the dashboard menu instead of shutting it down entirely. Keep your sensors clean, and keep safety your top priority on the road.
