This thread consolidates information from pages 132 and 641 of your 2024+ Toyota Tacoma (4th Gen) Owner's Manual, providing a complete guide to understanding and customizing the rear seat reminder feature. Tacoma Rear Seat Reminder: Settings, Enable & Customize The rear seat reminder is a convenience feature designed to help prevent you from accidentally leaving luggage, cargo, or passengers in the rear seats when you exit your vehicle. When the engine switch is turned OFF after certain conditions are met, the system alerts you with a buzzer sound and a message on the multi-information display for approximately 6 seconds. How It Works The system detects when rear doors have been opened and closed. It determines that items may be in the rear seat based on this door activity, not by detecting actual objects. Two Triggering Scenarios: Scenario 1: The engine is started within 10 minutes after opening and closing a rear door. Scenario 2: A rear door is opened and closed after the engine has already been started. When either condition occurs, the reminder activates the next time you turn off the engine. Important Limitations Timing Sensitivity: If a rear door is opened and then closed within approximately 2 seconds, the reminder may NOT activate. This prevents false alarms from brief door openings. False Negatives: The system may NOT remind you if: - You open a rear door to access cargo but never place items inside - Door activity is minimal or incomplete False Positives: The system may remind you unnecessarily if: - You open a rear door briefly without placing anything inside - Door activity triggers detection even though no items are present Best Practice: Physically check the rear seats before locking your vehicle. Safety Information WARNING: To Prevent an Accident Observe the following precautions while driving the vehicle. Failure to do so may result in a door opening and an occupant falling out of the vehicle, resulting in death or serious injury: • Ensure that all doors are properly closed and locked before driving • Do not pull the inside handle of the doors while driving. Be especially careful for the front doors, as the doors may be opened even if the inside lock buttons are in locked position • Set the rear door child-protector locks when children are seated in the rear seats When Opening or Closing a Door: Check the surroundings of the vehicle such as whether the vehicle is on an incline, whether there is enough space for a door to open, and whether a strong wind is blowing. When opening or closing the door, hold the door handle tightly to prepare for any unpredictable movement. - Source: 2024+ Toyota Tacoma Owner's Manual, Page 132 Customizing the Rear Seat Reminder Menu Location Access the rear seat reminder setting through your vehicle's customization menu in the Vehicle Specifications section. Current Configuration Options Function: "Indication to prevent misplacement in the rear seat" Default Setting: ON (enabled) Customizable Options: ON or OFF How to Disable Navigate to the customization menu and toggle the rear seat reminder setting from ON to OFF. This will disable the reminder notifications while driving. - Source: 2024+ Toyota Tacoma Owner's Manual, Page 641 Community Tips & Real-World Experience Based on feedback from 4th Gen Tacoma forums (Tacoma4G, TacomaWorld, ToyotaNation): Helpful Tips Use the Toyota Mobile App: You can disable rear seat reminder notifications through the official Toyota mobile app. Access: App menu → Account → Notification Settings → Toggle rear seat reminder off. Advanced Customization Option: Owners seeking deeper control over vehicle settings can use the Carista OBD2 diagnostic tool for dealer-level customization options. Understand Related Systems: The rear seat reminder (triggered by door activity) is separate from the seatbelt occupancy sensor (triggered by weight on seats). Common Situations & Workarounds Frequent Cargo Haulers: Some owners experience repeated alerts if carrying items in rear seats. Standard menu settings primarily control display messages. Seatbelt False Alarms: Don't confuse the rear seat reminder with seatbelt sensors. Clasping seatbelts suppresses seatbelt alerts (though access becomes cumbersome). Why Full Disablement Isn't Available: Toyota intentionally limits complete disablement as a safety feature to prevent leaving children or pets in vehicles. - Source: Tacoma4G.com, TacomaWorld.com, ToyotaNation.com forums Frequently Asked Questions Q: Can I disable the reminder completely through the menu? A: The customization menu allows toggling the display message on/off, though the reminder system may still produce audio alerts under certain conditions. Q: Why do I get reminders when I didn't put anything in the rear seat? A: The system detects door activity, not object presence. Opening and closing a rear door triggers detection. Q: Can I control this from the Toyota app? A: Yes, disable notifications through the Toyota mobile app's account settings. Q: Is this the same as the seatbelt warning chimes? A: No, these are separate systems. Rear seat reminder detects door activity; seatbelt system detects seat weight.

I just got my Tacoma on 9/13/24 and now with barely 1k miles on it and after simply running errands around town, The dash lights up with check engine, system malfunction, drive assist malfunction etc etc and it struggles to start. wtf
So far the dealership has no idea what happened and they couldn't replicate the issue when I dropped the truck off. I'm calling bullsh#t on that. It happened to me 3 x and the tow truck driver as well. Anyone else have these issues that were explained?
Cmon Toyota, you can do better.
