Why is it important to know where the airbags are hidden in your car?
Have you ever wondered how many hidden security systems are running in your car while you drive to work or on vacation? Airbags are more than just "bags" that inflate during a crash. This is a complex engineering system hidden in the most unexpected places of the cabin. And if you're planning torpedo repair, door trim replacement or even banal installation of a child seat, ignorance of their exact location can result in serious injury if activated accidentally or breakdown of expensive equipment.
Modern cars are equipped with up to 10-12 airbags (in premium models Mercedes S-Class or Volvo XC90 their number reaches 16!). They are divided into frontal, side, knee, curtain and even central (for example, in Toyota Camry 2023). At the same time, manufacturers specially disguise them as decorative panels so as not to spoil the interior design. But this “invisibility” plays a cruel joke: according to statistics NIIAT, 38% of airbag damage occurs during self-repair of a car, when owners accidentally touch the squibs with a screwdriver or drill.
Front airbags: where to look and how not to damage them
The most famous and first to appear - front airbags. They are installed on the driver and front passenger sides. In 99% of cases they can be detected:
- 🚗 Driver's airbag: hidden in center of the steering wheel (under the brand logo). In models BMW 5 Series or Audi A6 It is given away by a barely noticeable perforation on the leather braid.
- 👤 Passenger airbag: located in top of the torpedo on the front passenger side. Often disguised as a decorative cover with an inscription
AIRBAGorSRS.
The key feature of front airbags is that they deploy when frontal impact at speeds above 20-25 km/h (the threshold depends on the model). In this case, the squib is activated for 0.03-0.05 seconds - faster than you can blink. That's why never place heavy objects on the dashboard (such as a laptop or bag): when triggered, they will turn into a deadly projectile.
⚠️ Attention: If cracks, swelling or traces of melting appear on the steering wheel or dashboard, this is a sign squib malfunction. It is prohibited to operate such a car: the airbag may work spontaneously!
Side airbags: hidden dangers in doors and seats
Side airbags (side airbags) appeared later than the front ones, but today they are installed even in budget models (Kia Rio, Hyundai Solaris). Their main task is to protect the torso and pelvis during side impact (the most dangerous type of accident according to WHO). Where to look for them:
- 🚪 In door cards: in most cars (for example, Volkswagen Golf or Skoda Octavia) they are hidden in door trim at the passenger's chest level. Sign - vertical seam or inscription
SIDE AIRBAG. - 🪑 In the backs of the seats: in premium models (Mercedes E-Class, Lexus ES) side airbags are integrated into outer backrest front seat to protect rear passengers.
The peculiarity of the side airbags is that they work with less deformationthan frontal ones (sometimes an impact at a speed of 10-15 km/h is enough). Therefore, when body door repair or interior reupholstery be sure to disconnect the battery and use special ties for squibs (they can be rented at car services).
| Car model | Number of side airbags | Typical location |
|---|---|---|
| Toyota Corolla (2020+) | 2 (front) | In the backs of the front seats |
| Ford Focus (2018+) | 4 (front + rear) | In the doors and backrests of the front seats |
| Volvo XC60 (2023) | 6 (including curtains) | Doors, seats, ceiling |
| Lada Vesta (2022+) | 2 (optional) | Front seats only |
If you are buying a used car, have the side airbags checked using a diagnostic scan tool (eg Launch X431). Even if they are outwardly intact, the squib could have worked in a previous accident, and the pillow was “replaced” with a dummy.
Curtain pillows: invisible head protection
Some of the most difficult to detect are curtain airbags (curtain airbags). They are designed to protect passengers heads in a side impact or rollover. When unfolded, they resemble a curtain that falls along the windows from front pillar up to back door (in some models - up to the trunk).
Where to look for them:
- 🪟 Along the roof: hidden under headliner above the doors. B Honda CR-V or Mazda CX-5 they are identified by a thin line running parallel to the windows.
- 🚐 In the body pillars: in minibuses (Toyota Hiace) or large crossovers (Nissan Patrol) curtain pillows can be placed in front and rear pillars.
Curtain pillows work longer than others (up to 0.1 second) to cover the entire window area. Their main danger during repairs is damage to the squib when removing the headliner. For example, if you decide to install panoramic sunroof or LED interior lighting, be sure to study car electrical diagramso as not to confuse the pillow wires with the lighting wires.
What happens if the curtain airbag goes off when the window is open?
When triggered, the curtain cushion unfolds with a force of up to 200 kg/cm². If the window is slightly open, it can tear the glass out of the guides or deform the door frame. In the worst case, you could injure a passenger with broken glass.
Knee pads and other exotic options
Less known, but no less important - knee airbags (knee airbags). They protect the legs of the driver and front passenger from impact with the dashboard in a frontal collision. Found in:
- 🦵 Bottom of torpedo: in Subaru Outback or Mitsubishi Outlander they are hidden under glove box (glove compartment).
- 👨🔧 Under the steering wheel: on some models Lexus or Infiniti The driver's knee airbag is integrated into the lower part of the steering column.
Another rare type - center cushions (center airbag). They are installed between the front seats (for example, in Toyota Camry 2021) and prevent passengers colliding with each other in a side impact. They can easily be confused with an armrest, so when replacing seat covers or cleaning the interior with a steam generator be extremely careful.
⚠️ Attention: Knee pads are often damaged when incorrect installation of the alarm system or connecting the recorder to the cigarette lighter. Before any electrical work, turn off negative battery terminal and wait 10-15 minutes (this time is needed to discharge the capacitors in the system SRS).
How to check if all pillows are in place: step-by-step instructions
If you bought a used car or suspect that the previous owner hid the fact of an accident, here's how to check the presence and functionality of the airbags:
Visual inspection for signs of repair (uneven seams, fresh paint)
Diagnostics with a scanner (error codes B1xxx or U0xxx indicate problems with SRS)
Checking the VIN code via CarVertical or Autocheck on the fact of an accident
Test drive with hard braking (some faults appear due to vibration)
-->
Pay special attention to:
- 🔍 Trigger traces: melted contacts under the steering wheel, powder deposits on the dashboard or doors (these are the remains of the squib).
- 📋 Documents: in service book there must be a note about the replacement of airbags after an accident. If it is not there, and the car is damaged, this is a reason for bargaining.
For an in-depth check, use diagnostic commands (for example, VAG groups through VCDS):
Adaptation of the SRS unit (Airbag) → Test of actuators → Code 001 (front airbags)What to do if the airbag works: restoration and replacement
If the airbag is deployed (even partially), it cannot be restored - only complete replacement. Here's what to do:
- Disconnect the battery and wait for the capacitors to discharge (at least 15 minutes).
- Replace the pillow for a new one (original or certified analogue from TRW, Autoliv).
- Check the shock sensors (they can be damaged even in a minor accident).
- Reset errors in the block
SRSthrough a diagnostic scanner.
Replacement costs vary:
| Pillow type | Average price (original) | Cost of work |
|---|---|---|
| Front (driver) | 15 000 — 40 000 ₽ | 3 000 — 6 000 ₽ |
| Side (in the door) | 8 000 — 25 000 ₽ | 4 000 — 8 000 ₽ |
| Curtain | 20 000 — 50 000 ₽ | 5 000 — 10 000 ₽ |
⚠️ Attention: When buying pillows from a salvage yard, ask for warranty for the squib (the shelf life of original cartridges is 10-15 years). Counterfeits often explode during installation!
Never buy a car with "remanufactured" airbags. Even if they are outwardly intact, the squib could have been damaged during dismantling, and the airbag would not work at a critical moment.
FAQ: Frequently asked questions about airbags
Is it possible to turn off the airbags if they are in the way?
Technically yes, but this illegally (in Russia, a fine of up to 500 rubles under Article 12.5 of the Administrative Code). Disabling is only allowed for medical indications (for example, for epilepsy) - a doctor’s certificate is required. In other cases, you risk your life: in the event of an accident, the insurance company may refuse to pay, citing violation of operating rules.
Why don't my car have side airbags?
Side airbags began to be installed en masse only after 2005. If your car is older (eg. VAZ 2110 or Daewoo Nexia), they might not be available even in top trim levels. Today they are mandatory for Euro 5 and above. Check the package using the VIN code on the manufacturer's website.
Is it possible to wash the interior with a steam generator if there are pillows?
You can, but with caution:
- Do not direct the steam jet at sheathing seams (there may be squibs there).
- Use a temperature no higher 100°C.
- Disconnect the battery before cleaning.
It is better to entrust cleaning to professionals with experience in working with SRS-systems.
Do the rollover airbags deploy?
Yes, but not all. Curtain pillows and seat belt squibs (in models with pretensioners) are triggered in the event of a rollover if the vehicle is equipped roll sensor (for example, Volvo XC90 or Range Rover). The front and side airbags remain inactive.
How often should airbags be checked?
Manufacturers recommend diagnostics SRS-systems:
- Once every 5 years or every 100,000 km (whichever comes first).
- After any accident, even a minor one.
- When an error occurs
AIRBAGon the dashboard.
The check takes 10-15 minutes and costs from 500 ₽ per service.
