Front airbags (front airbags) is a key element of vehicle passive safety that saves lives in frontal collisions. However, many drivers still do not know where exactly are they installed? and how to correctly identify them. This article will examine not only the standard locations of airbags in the steering wheel and front panel, but also the nuances of their design that affect safety.

You will be surprised, but even in modern cars, front airbags can be hidden in a non-obvious way - for example, under the dashboard trim or in non-standard areas of the cabin. And if you are planning to buy a used car, knowing their exact location will help you avoid unpleasant surprises: from hidden damage after an accident to incorrect operation of the system SRS (Supplemental Restraint System).

We will also look at how to independently check the performance of airbags without a diagnostic scanner, what signs indicate their deployment or damage, and why even visually intact airbags may be unsafe after an accident. At the end of the article there is a checklist for inspecting a car and answers to frequently asked questions.

1. Standard locations of front airbags

In 99% of passenger cars, front airbags are installed in two main areas:

  • πŸš— Steering wheel β€” driver's airbag. Usually hidden under the central part of the steering wheel (behind the brand logo) or in the spokes.
  • πŸ“± Front panel (dashboard) β€” passenger airbag. Located behind a plastic cover above the glove compartment, often with the inscription AIRBAG or SRS.

However, there are nuances:

  • πŸ” In some models (for example, Toyota Camry or Honda Accord) the passenger airbag can be integrated into top of the panel, closer to the windshield, and not above the glove compartment.
  • πŸ› οΈ In older cars (before the 2000s), airbags could only be installed on the driver's side - the passenger side was an option.
  • 🚘 In minibuses and commercial vehicles (for example, Mercedes Vito) frontal airbags are sometimes duplicated for second-row passengers.

Important: even if the pillows are not visually visible, they can be hidden under the trim. For example, in Tesla Model 3 The passenger airbag is hidden behind a smooth panel without seams - its location is revealed only by a small icon AIRBAG on plastic.

πŸ“Š How often do you check the condition of the airbags in your car?
Never checked
Only when buying a used car
Regularly (once a year)
Only after an accident

2. What do front airbags look like from the inside: structure and materials

The front airbag is more than just a bag of air. It consists of several key components:

Component Material/design Purpose
Gas generator (squib) Metal body with solid fuel (sodium nitrate, potassium nitrate) Quick filling of the airbag with gas when triggered
Tissue shell Nylon or polyester with silicone coating Holds gas and absorbs shock
Cover (decorative panel) Plastic with weakened fault lines Breaks when triggered without creating sharp edges
Shock sensors Electronic sensors (piezoelectric elements or accelerometers) Determine the force and angle of collision

Fun fact: in pillows BMW 5 Series (G30) and Audi A6 (C8) are used two-stage gas generators. They fire at different rates depending on the force of the impact, reducing the risk of injury in minor accidents.

But in budget models (for example, Renault Logan or Kia Rio) often install single-stage systems that open with maximum force, regardless of the severity of the accident. This may be dangerous for children or small people.

If, when inspecting a used car, you see traces of glue or uneven gaps on the plastic cover of the airbag, this is a sign of its replacement or unqualified repair after operation.

3. How to check front airbags before buying a car: 5 key signs

When inspecting a used car, pay attention to the following details:

  1. Visual traces of operation: cracks or tears on the plastic cover of the steering wheel/panel, traces of burning (from the squib) on the back of the trim.
  2. Lamp AIRBAG on the dashboard: if it lights up or flashes, there is an error in the system (possibly disabled airbags).
  3. Uneven gaps between plastic panels - a sign of disassembly of the interior after an accident.
  4. VIN number mismatch: check whether the year of manufacture of the airbags (indicated on the label of the gas generator) matches the year of the car.
  5. Checking with a diagnostic scanner: Even if the lamp is not lit, there may be errors in the memory (for example, B1000 β€” driver's airbag malfunction).

Pay special attention to cars after front impact. Even if the airbags did not deploy, they could have been damaged:

  • πŸ”₯ Gas generator overheating in case of a short circuit in the wiring.
  • πŸ’₯ Mechanical displacement impact sensors (for example, after repair of side members).
  • πŸ”§ Incorrect assembly after replacing the steering wheel or dashboard.

⚠️ Attention: If a seller claims that the pillows are β€œrecharged,” it’s a scam. Front airbags are disposable: after deployment, they must be replaced with new ones, not β€œrebuilt”. Such β€œrepairs” are extremely dangerous - the airbag may not work in a critical situation.

4. Where frontal airbags are NOT: common myths

There are several misconceptions about the location of front airbags that can be misleading:

  • ❌ Myth 1: "Cushions are installed in the doors." In fact, there are lateral pillows (side airbags), and the front ones are only in the steering wheel and panel.
  • ❌ Myth 2: β€œOld cars don’t have airbags.” Even in VAZ-2110 (since 2003) and Daewoo Nexia (since 1998) front airbags were installed as an option.
  • ❌ Myth 3: β€œThe passenger airbag is always larger than the driver’s.” B Volvo XC90 and Mercedes S-Class both pillows have the same volume (up to 60 liters).
  • ❌ Myth 4: "The airbags only deploy in the event of a frontal impact." In fact, they are activated when severe side collision, if the sensors detect a forward displacement of the body.

Another common misconception is that airbags deploy when any accident. In fact, they are only activated upon impact with an acceleration above 30–50 g (depending on the model). For example, when parking at a speed of 5 km/h, the airbags will not deploy, even if the bumper is damaged.

How do shock sensors work?

Front airbag sensors are usually located at the front of the vehicle (behind the bumper or in the side members) and in the control unit SRS. They analyze not only the force of the impact, but also its direction. For example, when hitting a curb at an angle of 30Β°, the airbags may not deploy, but in a head-on collision at a speed of 40+ km/h, they deploy instantly (deployment time is 20–50 ms).

5. What to do if the front airbags are deployed: algorithm of actions

If your car's front airbags deploy, follow this plan:

  1. Disconnect the battery (remove the minus terminal) to avoid accidental activation of undisconnected squibs.
  2. Do not touch gas generators - they can be hot (the temperature when triggered reaches 300Β°C).
  3. Inspect the interior for debris: When the plastic cover breaks, it may create sharp edges.
  4. Check the block SRS for errors (diagnostic scanner required). Often, after the airbags are deployed, the unit is β€œlocked” and requires flashing.
  5. Replace any tripped components:
    • πŸ”§ Airbags (driver and passenger).
    • πŸ”§ Gas generators and seat belt squibs.
    • πŸ”§ Shock sensors (if they are triggered).

⚠️ Attention: If the airbags are deployed when minor impact (for example, at speeds up to 20 km/h), this may indicate malfunction of sensors or unit SRS. In this case, a complete diagnosis of the system is required, since false alarms are dangerous.

The cost of replacing front airbags varies:

  • πŸ’° Budget cars (Renault, Kia, Hyundai): 15,000–30,000 β‚½ for components + labor.
  • πŸ’° Premium segment (BMW, Mercedes, Audi): 50,000–120,000 β‚½ (due to the high cost of original pillows and sensor calibration).
  • πŸ’° Electric cars (Tesla, Nissan Leaf): up to 150,000 β‚½ - due to the integration of airbags with the autopilot system.
πŸ’‘

Never buy used airbags at a salvage yard! Even if they are apparently intact, the gas generator could degrade over time, and the fabric could lose strength. This is deadly.

6. Is it possible to turn off the front airbags and when is it allowed?

Disabling front airbags prohibited in most countries, including Russia (according to Technical Regulations of the Customs Union 018/2011). However there is exceptions:

  • πŸ‘Ά Transportation of children in a child seat installed in the front seat (passenger airbag only).
  • πŸ‘¨πŸ¦½ People with medical conditions (for example, if there is a risk of injury from airbag deployment).
  • πŸš— Sports carsracing (requires certified replacement for racing safety systems).

How to disable the passenger airbag (if allowed):

  1. Find switch (usually located at the end of the panel on the passenger side, next to the glove compartment). It could be:
    • πŸ”˜ Key (requires turning the key).
    • πŸ”„ Push-button (with indication OFF).
  • Make sure the dashboard light comes on PASS AIRBAG OFF.
  • After disconnecting necessarily Move the passenger seat as far back as possible - without a cushion, the risk of injury in an accident increases.
  • ⚠️ Attention: Driver airbag deactivation unacceptable - this violates safety requirements and may cause denial of insurance payment in case of an accident. If the airbag is in the way (for example, due to the driver's short stature), it is better to adjust the steering wheel position or use steering wheel pads with shock absorption.

    7. How to care for front airbags: tips for extending their service life

    Although airbags are designed to 10–15 years of service, their performance depends on operating conditions. To avoid premature wear:

    • 🌑️ Avoid overheating the interior: Temperatures above 80Β°C (for example, when parked in the sun for a long time) accelerate the degradation of the squibs.
    • πŸ’¦ Do not wash the steering wheel or dashboard with harsh chemicals. - they can damage the plastic cover of the pillow.
    • πŸ”‹ Keep an eye on your battery: at low voltage (less than 9 V) block SRS may fail.
    • πŸ› οΈ Do not repair the steering wheel or panel yourself β€” even a slight displacement of the sensors can lead to false alarms.

    If your car is older than 10 years, it is recommended:

    1. Check pillow production date (indicated on the gas generator label).
    2. Contact service for squib resistance test (the norm is 2–4 ohms).
    3. If there are signs of corrosion on the contacts replace connectors systems SRS.

    Interesting fact: in Volvo and Saab airbags are tested for aging β€” they are artificially β€œaged” at elevated temperatures and humidity in order to check their reliability after 20 years of operation.

    FAQ: Frequently asked questions about front airbags

    Is it possible to install front airbags on a car that did not have them from the factory?

    Technically possible, but illegally. This requires:

    1. Install the control unit SRS and shock sensors.
    2. Route the wiring with proper interference protection.
    3. Obtain permission from the traffic police (vehicle conversion).

    The cost of such an upgrade often exceeds the market price of the car. It is much easier to buy a car with factory airbags.

    Why didn't the airbags deploy after the accident?

    The reasons may be different:

    • πŸ“‰ Impact speed too low (less than 20–25 km/h).
    • πŸ”Œ Disabled sensors (for example, after unqualified repairs).
    • πŸ”‹ Low battery - block SRS did not receive food.
    • πŸš— The blow did not come into the trigger zone (for example, at the corner of the bumper).

    If the airbags do not deploy during a serious accident, this is a reason for examination β€” the system may have been damaged previously.

    Is it possible to paint a plastic pillow cover?

    Yes, but with reservations:

    • βœ… Permitted to use soft dyes (for example, for plastic Vinyl Dye).
    • ❌ It is forbidden to apply thick layers of paint or varnish - this may prevent the lid from tearing when triggered.
    • ⚠️ Check after painting integrity of fault lines on the lid.
    What to do if cracks appear on the pillow?

    Cracks on plastic cover (not on the pillow itself!) are not critical, but:

    • If the cracks are deep (more than 1 mm), replace the cover (cost: 2,000–5,000 β‚½).
    • If there are cracks on fabric cover of the pillow β€” a complete replacement of the module is required.

    Do not attempt to seal cracks; if triggered, this may result in uncontrolled rupture.

    How can you find out if the airbags in your car have deployed if they have already been replaced?

    Signs of a hidden trigger:

    • πŸ” Traces burning or soot on the back of the panel/steering wheel.
    • πŸ”§ Inconsistency production dates pillows and car year.
    • πŸ“‹ Presence of errors in the block SRS (even if the lamp is not on).
    • πŸ“„ Checking car history by VIN (services CarVertical or Autocode may show records of repairs after an accident).
