Hello, and thank you for your letter. Like the seat belt light, the passenger seat airbag is triggered by weight when a passenger sits in the seat. Only when there is sufficient weight to trigger the mechanism will the sensor, which is housed inside the seat frame, switch on. This is one method of reducing the engine’s ongoing energy use, and it is believed that operating the system less will increase the longevity of the parts. More details about this should be available in your owner’s manual. The sensor may have failed if the airbag sensors continue to indicate that the system is off when a person is seated in the seat. In this situation, you should have the sensor checked out and potentially replaced. Contact our service division for additional assistance with the system’s diagnosis.

How can I activate the passenger airbag?
If the vehicle has a switch called the Passenger Airbag Cut Off Switch, it can be used to deactivate the passenger airbag (PACOS).
When the passenger door is open, you may access the switch for the passenger airbag on the passenger side of the instrument panel.
ALL FRONT-FACING PASSENGERS (CHILDREN AND ADULTS) CAN SIT SAFELY ON THE PASSENGER SEAT WHEN THE AIRBAG IS ACTIVATED.
Rear-facing child seats are safe for use on the passenger seat when the airbag is switched to OFF.
My passenger airbag is not on; why?
If your passenger is light enough for the weight sensor to notice that they are in the seat but not so light that it would be prudent to deploy the airbag, your passenger airbag will not deploy. The airbag’s deployment would be risky for the person in this chair, according to the sensor, because they are too light.
Is it normal for the passenger airbag off light to be on?
The Passenger Air Bag Off Light in the dash will illuminate if the passenger sensing system determines that no one is occupying the passenger front seat or if a number of other circumstances apply. It’s critical that you understand what this means:
- You can also not have the passenger air bag deployed.
- In the event of a collision, the air bag will not deploy.
- Front passenger airbag is not deployed.
When an adult-sized passenger is seated in the front seat and the Passenger Air Bag Off Light is illuminated, this typically indicates that the person is not seated properly.
Have the automobile inspected if the passenger adjusts their position and the light does not go out.
It might be necessary to shut off and restart the engine to get the light to turn off.
Why is my Lexus’ airbag light on?
It is a sign that there is an issue with your vehicle’s supplemental restraint system. If this warning light illuminates, one or more airbags can fail to deploy during a collision. The SRS module, crash sensor, or other parts of the airbag system could be having issues.
How do I restart my airbags?
When you experience the same problem, you should start by following this technique, which is identical to resetting the airbag light on a Toyota Camry. It needs timing the airbag light and has four straightforward stages that are simple to complete.
First, activate the ignition. Wait for the airbag light to turn on next; it typically illuminates for seven seconds before turning off automatically. After waiting three seconds, immediately flip the ignition switch off. Before starting the engine, go through the basic procedures a couple of times. Your car’s airbag light should illuminate for seven seconds before turning off permanently if everything is done correctly.
How does a Lexus RX 350’s passenger airbag deactivate?
The Passenger Airbag Cut Off Switch (PACOS) is often located on the dashboard on the passenger side. Depending on the make and model of your car, you might find this in the glovebox or on the side of the dashboard.
When the airbag light is on, can you drive?
The airbag light may have illuminated for any number of reasons, just like other warning lights. Here are a few of the most frequent causes:
The airbag needs resetting
The airbag light will turn on if there has been a collision but it wasn’t serious enough for the airbags to deploy. At your neighborhood garage, the airbag needs to be reset.
Corroded sensors
The sensors in your automobile may have deteriorated if it has water damage. This would lead to a malfunction in the system and turn on the airbag light.
Dislodged wiring
If your car has side airbags, the passenger side airbag may occasionally malfunction. When the passenger seat is shifted back and forth, the wires for that airbag may become damaged or displaced. We caution against attempting to reconnect a disconnected plug because you risk setting off the airbag. Make an appointment for your car at a nearby garage and ask them to check it.
Faulty seat belt
Your seat belt sensor can be the cause of the problem. The sensor that determines whether or not you have buckled up can malfunction occasionally. When this occurs, the airbag light can start to illuminate.
Your airbag clock spring may need replacing
The spring is intended to preserve continuity between the wiring and the driver’s airbag and coils throughout your steering wheel. The spring may wear out and fail over time, turning on the airbag warning light. Older autos are more likely to have this flaw.
The important line is that you must stop driving as soon as your airbag light illuminates and have your automobile inspected by a repair as soon as possible. Your airbags won’t activate until the issue is identified and remedied. Never disregard your airbag light since your safety and the safety of your passengers are top priorities.
What weight triggers the passenger airbag to deactivate?
This sensor chooses the ideal airbag deployment force during a collision. 8. Front passenger seat weight sensors. If there is less than about 65 lbs (29 kg) on the seat, the front passenger’s airbag will not deploy (the weight of an infant or small child).
What does the airbag off light for the passenger mean?
If you’ve ever placed a bag of groceries or another object of a similar weight on the front passenger seat of your car and noticed that the “airbag off” sign came on, it means that your automobile has decided that the object is riding shotgun does not require a frontal airbag.
The passenger airbag isn’t present.
Since the 1999 model year, all vehicles, light trucks, and vans must include driver and passenger airbags for frontal crash protection, per federal law.
In moderate to severe frontal collisions, front airbags are intended to deploy to cushion the occupant’s head and chest from impacting the car’s metal frame.
Although they are made to offer protection for all passengers, they offer the best protection when passengers are buckled up and seated properly.
In order to determine whether to deploy the airbag in a specific crash, more recent airbags incorporate a safety belt sensor and utilize an algorithm to determine whether people are wearing safety belts.
Unbelted passengers who are involved in crashes that are the equivalent of hitting a rigid wall at 10 to 12 mph will typically have their front airbags deploy. Because seat belts alone are expected to provide adequate protection up to these modest speeds, the majority of airbags will only deploy at a higher thresholdabout 16 mphfor belted individuals.
If there is enough forward motion during the incident, front airbags may deploy to help protect people in side hits.
The steering wheel houses the driver airbag. The dashboard houses the passenger airbag.
Some manufacturers offer additional, lower-mounted knee airbags. In order to lessen leg injuries, knee airbags are designed to disperse impact forces. By limiting the movement of the occupant’s lower body, they may also assist in lessening stresses on the chest and abdomen.
What does it cost to fix the airbag light?
Reset Airbag Light, at No. 1 This procedure typically takes several hours and costs a few hundred dollars, though depending on the car, it might cost as much as $600.
