The Toyota Highlander is a popular midsize SUV known for its combination of style, power, and safety features. One of the essential safety components in the vehicle is the front passenger airbag. However, there are situations—such as when the passenger seat is unoccupied or when a child is seated in a rear-facing car seat—where the airbag might be automatically turned off. Understanding how to turn on the passenger airbag in your Highlander is crucial to ensure maximum safety for adult passengers riding in the front seat.
In this detailed guide, we’ll walk you through everything you need to know about activating or enabling the front passenger airbag in your Toyota Highlander, including safety procedures, indicator lights, potential troubleshooting points, and much more.
Understanding the Passenger Airbag System in the Toyota Highlander
Before diving into the steps to turn on the airbag, it’s necessary to understand how the airbag system works in a Toyota Highlander.
The front passenger airbag is part of the vehicle’s Supplemental Restraint System (SRS), which includes airbags, seat belt pre-tensioners, and various sensors. This system is designed to deploy airbags in the event of a significant frontal collision to help protect occupants.
The Role of the Passenger Airbag On/Off Switch
In some Highlander models, particularly older ones, there is a passenger airbag on/off switch located on the passenger side of the dashboard, accessible when the passenger door is open. This switch allows you to manually control the airbag deployment. However, more recent models (typically from 2006 onwards) use an automatic Occupant Classification System instead.
Automatic Occupant Classification System (AOCS)
Newer Highlander models are equipped with an AOCS, which uses sensors to detect the presence and weight of an occupant in the front passenger seat. If the system detects that the seat is empty or occupied by a small child (especially in a rear-facing car seat), it will automatically deactivate the front passenger airbag to prevent injury in the event of an airbag deployment.
The “Passenger Airbag Off” indicator light on the dashboard will illuminate if the automatic system has turned off the airbag.
If you have an automatic system, manually turning the airbag on is not recommended unless you are certain that an adult is seated in the passenger seat. The system is designed for safety and will usually activate the airbag when appropriate.
Step-by-Step Guide: How to Turn On the Passenger Airbag
Whether you have a manual switch or an automatic system, here’s how to turn on the passenger airbag in a Toyota Highlander.
For Models with Manual Airbag Control
- Ensure you are stationary: Before attempting to adjust the airbag setting, make sure the vehicle is parked and the engine is off.
- Locate the switch: The passenger airbag switch is found on the passenger side dashboard. It’s typically labeled “AIRBAG” and has two positions: “ON” and “OFF.”
- Insert a key or switch tool: Some models require a specific tool or the ignition key to turn the switch.
- Turn the switch to “ON”: Rotate it toward the “ON” position. You may hear a click confirming the change.
- Start the vehicle: The “Passenger Airbag Off” light should turn off, indicating the airbag is now enabled.
It’s important to remember that manually turning on the airbag when a child or infant is in the front seat is unsafe and could lead to serious injury or death if the airbag deploys.
For Models with Automatic Airbag System
- Ensure the passenger seat is occupied: The system must detect weight on the seat. Simply placing an object won’t work—the system is calibrated to recognize human weight distribution.
- Adjust the seating position: Have the passenger sit upright and centered on the seat for accurate sensor readings.
- Remove the car seat: If a rear-facing infant seat is attached to the front passenger seat, the system will automatically turn off the airbag. Once the seat is removed, the system should reactivate the airbag.
- Check the indicator light: If the light is off, the airbag is active. If it remains on, you may need to reset the system or check for errors.
Indicator Lights and What They Mean
The dashboard of the Toyota Highlander displays various warning lights, and knowing what they mean is essential for ensuring your vehicle is functioning properly.
Passenger Airbag Off Indicator Light
This light appears as the silhouette of a person sitting in the front passenger seat with a large circle (representing the airbag). When illuminated, it indicates that the front passenger airbag is not active.
The light is part of a system designed to protect passengers from unnecessary airbag deployment that might be harmful, such as when a small child or no one is in the seat.
Why the Light Might Stay On
- A child seat is installed in the front passenger seat
- The front seat is unoccupied
- The passenger is not seated correctly
- There’s a problem with the weight sensors or the SRS system
If the light refuses to turn off even with an adult in the seat, further troubleshooting may be necessary.
Common Issues and Troubleshooting Tips
Even though the Highlander’s airbag system is designed to be reliable, there are times when it may not function properly.
Problem: The Passenger Airbag Is Turned Off and Won’t Activate
- Step 1: Ensure the seat is properly occupied. An adult should sit in the seat for a few moments to allow the system to detect the weight.
- Step 2: Check for objects on the seat. Even placing a heavy bag or coat can interfere with sensor readings.
- Step 3: Reset the system by turning the car off and back on. Sometimes, simply cycling the ignition can reset the sensor.
If these steps don’t resolve the issue, it may indicate a problem with the sensor or the SRS system.
Problem: The Indicator Light Stays Off When No One Is in the Seat
This behavior is actually normal. The light turns on only when the airbag is deactivated. If the passenger seat is empty, the airbag is turned off, but the indicator light is not illuminated because there’s no need to notify the driver. If someone sits down and the light doesn’t turn off, that’s when an issue arises.
Using Aftermarket Seat Covers
While seat covers are a great way to protect your vehicle’s interior, some thick or high-tech covers can interfere with the occupant detection sensors. If you’ve noticed the “Passenger Airbag Off” light staying on with an adult in the seat, removing the seat cover and testing the system may help.
System Malfunction or SRS Warning Light
If another airbag warning light illuminates (such as a general SRS or airbag light), or if problems persist despite troubleshooting, it’s important to have your vehicle inspected by a qualified technician. The airbag system is complex and computerized, and malfunction can lead to serious safety concerns.
Best Practices for Passenger Airbag Use
To get the most out of your Highlander’s airbag system and ensure optimal safety, follow these best practices:
1. Never Use a Rear-Facing Car Seat in the Front with an Active Airbag
If you must install a rear-facing infant seat in the front passenger seat, you must manually turn off the airbag to protect the child in the event of deployment. However, it’s always safer to install rear-facing car seats in the back seat whenever possible.
2. Always Use Seat Belts
Passenger airbags are designed to work in conjunction with seat belts. Even if the airbag is active, not wearing a seat belt can lead to injury. Make sure all passengers buckle up for both comfort and safety.
3. Keep Children in the Back Seat
Children under 13 should ride in the back seat of the Toyota Highlander, preferably in an appropriate car seat or booster seat. This helps prevent injuries in the event the airbag deploys.
4. Adjust Seat Position Properly
Sitting too close to the airbag (less than 10 inches away) can increase the risk of injury. Adjust the seat as far back as comfortable while still being able to reach controls safely.
5. Follow Manufacturer Recommendations
Toyota provides detailed guidance on the airbag system in the owner’s manual. Refer to this manual for model-specific instructions on the usage, location, and safety precautions regarding the front passenger airbag.
When Is It Required to Turn On or Off the Passenger Airbag?
There are specific scenarios where you may need to manually override the system, especially if your Highlander has a manual switch.
Situations Where the Airbag Should Be On
- An adult is seated in the front passenger seat
- The occupant is properly wearing a seat belt
- No rear-facing car seat is installed
Situations Where the Airbag Should Be Off
- A rear-facing car seat is secured in the front passenger seat
- The seat is unoccupied
- A small child is sitting in the front seat (under age 13, per best practice)
It’s critical to make sure the airbag is in the correct setting depending on who is occupying the seat. Incorrect use could either disable a life-saving device or unnecessarily expose someone to airbag force.
Safety Standards and Legal Considerations
The National Highway Traffic Safety Administration (NHTSA) has issued guidelines regarding the use of airbags, child seats, and occupant placement in vehicles. Some states may also have specific laws regarding children in front seats.

Where is the passenger airbag switch located in a Toyota Highlander?
The passenger airbag switch in a Toyota Highlander is typically located on the passenger side of the dashboard, near the glove compartment. It is designed to be accessible for the driver or front passenger to toggle it on or off as needed. The switch is often labeled with an airbag icon and may have “ON” and “OFF” indicators. Some models may also include an indicator light that illuminates when the airbag is deactivated.
Before attempting to toggle the airbag, ensure the vehicle key is in the “On” position or that the engine is running, as the system requires power to operate. If the switch is labeled differently or not easily found, refer to your owner’s manual for the precise location based on your Highlander’s specific model year. Toyota designed this airbag control feature with safety in mind, especially for instances when a child sits in the front seat or when a front passenger has specific medical conditions.
How do I know if the passenger airbag is turned on in my Toyota Highlander?
Your Toyota Highlander includes an indicator light on the dashboard that alerts you to the status of the passenger airbag system. When the passenger airbag is turned on, the indicator light will either be off or display “Airbag On,” depending on the model. If the switch is set to “ON” and the indicator light illuminates as expected, the airbag system is active and ready to deploy in the event of a collision.
If the indicator light shows “Passenger Airbag Off” or an airbag warning light remains illuminated after toggling the switch, it could indicate an issue with the airbag system or a misalignment in the switch. In some cases, the system may automatically deactivate the passenger airbag if it detects a small weight or improper seating position via the seat sensor. Always confirm the indicator shows “On” before assuming the airbag is active.
Can I turn on the passenger airbag while the vehicle is moving?
Yes, it is possible to turn on the passenger airbag while your Toyota Highlander is moving, but it is recommended to do so only when it is safe to access the switch and ensure your vehicle is stationary. If the front passenger seat is occupied while driving, you should wait until the vehicle is parked before adjusting the airbag settings. For safety reasons, Toyota advises changing airbag settings before driving or during stops with the engine still running.
Performing this operation while driving could distract the driver or affect the front passenger’s safety. Additionally, the system may take several seconds to recognize the change in switch position and update the airbag status accordingly. Always confirm the indicator light shows the correct setting after toggling the switch, and refer to your owner’s manual for any limitations specific to your model year.
Is it safe to keep the passenger airbag on for a rear-facing infant seat?
No, it is not safe to keep the passenger airbag on when using a rear-facing infant seat in the front seat of your Toyota Highlander. If the airbag deploys during a collision or sudden stop, it can cause serious injury or death to the infant due to the force and speed at which the airbag inflates. Toyota, like most vehicle manufacturers, strongly advises against placing rear-facing car seats in the front seat if the airbag cannot be switched off.
If the front passenger seat is the only available option, for reasons such as limited back seat space or vehicle modifications, it is crucial to turn off the passenger airbag first. Always switch the airbag off before placing a rear-facing car seat in the front seat and verify its deactivated state via the indicator light. It’s best to use the back seat for infant car seats so that the airbag can remain activated for adult passengers.
What should I do if the passenger airbag indicator does not respond after switching it to “On”?
If the passenger airbag indicator in your Toyota Highlander does not respond after switching it to “On,” first confirm that the switch was fully toggled to the correct position. A loose connection or partially engaged switch can prevent the airbag system from registering the change. Cycle the switch off and then back on again, waiting a few seconds for the system to respond. Ensure that the vehicle ignition is in the “On” position during this process.
If the indicator still does not respond or remains in the wrong state, you may have a defective switch or a system malfunction. In this case, it is advisable to consult a Toyota dealership or certified mechanic to diagnose and fix the issue. The airbag system is critical for safety, and any anomalies should be addressed promptly. Do not rely on manual switch adjustments without verifying the indicator light is functioning properly.
Can the passenger airbag be manually turned on for a child passenger?
No, Toyota does not recommend manually turning on the passenger airbag for a child passenger in the Toyota Highlander. Airbags are designed for adult occupants and can pose a serious safety risk to children due to the force of deployment. For safety, Toyota advises that children under age 13 sit in the rear seats of the vehicle where they are better protected.
If a child must ride in the front seat—for instance, due to medical or space limitations—they should be in a forward-facing car seat with the seat positioned as far back as possible. In some cases, depending on the child’s size and maturity, they may be able to safely sit in the front with the airbag on. However, it is always best to consult guidelines specific to your Highlander model and a certified child safety expert or your vehicle’s owner’s manual.
Why is the passenger airbag on my Toyota Highlander not turning on automatically?
The passenger airbag in your Toyota Highlander may not turn on automatically because the system uses weight sensors to detect a passenger’s presence. If the front seat is unoccupied or a light load is detected—such as a heavy bag or small child—the airbag system may remain disabled to prevent unnecessary or hazardous deployment. This automatic function ensures additional safety in vehicles equipped with occupant classification systems.
If the system fails to activate the airbag for an adult passenger, check if the switch is manually set to “Off” or if there is an issue with the sensing mechanism. Interference from floor mats or improper seating posture can also affect the detection system. Ensure that the passenger is seated correctly and that the vehicle’s software and airbag system are up to date. If the problem persists, consult a professional mechanic to inspect the sensors and system functionality.
