Land Rover Discovery Owners & Service Manuals

Land Rover Discovery: Airbag deployment effects

  • When an airbag inflates, a fine powder is released. This is normal and not an indication of a malfunction. The powder may cause irritation to the skin and should be thoroughly flushed from eyes and any cuts or abrasions. This powder can cause breathing difficulties for asthma sufferers or other people with respiratory problems. If this occurs, get out of the vehicle as soon as it is safe to do so or get fresh air by opening a window. If breathing problems persist, seek medical attention.
  • Airbag deployment is accompanied by a very loud noise, which may cause discomfort, and temporary loss of hearing.
  • After inflation, some airbag components will be very hot. Do not touch the airbag components until they have cooled sufficiently.
  • After inflation, the front and seat-mounted side airbags deflate immediately. This provides a gradual cushioning effect for the occupants and also makes sure the driver's forward vision is not obscured.

AIRBAG WARNING LAMP

The airbag warning lamp is displayed in the Instrument panel and will illuminate as a bulb check when the ignition is switched on.

  • The warning lamp indicates a potential fault with the vehicle's restraint system, which could result in serious injury or death in the event of a severe accident.
  • If the warning lamp indicates that a fault is present in the system, do not use a child restraint on the front passenger seat.

If any of the following warning lamp conditions occur, the vehicle should be checked by your Retailer/Authorised Repairer immediately:

  • The warning lamp fails to illuminate when the ignition is switched on.
  • The warning lamp fails to extinguish within 6 seconds of the ignition being switched on.
  • The warning lamp illuminates at any time, other than during the bulb check, when the ignition is on.

When the ignition is switched on, a diagnostic control unit monitors the readiness of the system's electrical circuits.

The elements of the Supplementary Restraint System (SRS) components include:

  • SRS warning indicator.
  • Rotary coupler.
  • Airbag modules.
  • Front and third row seat belt pre-tensioners.
  • Front seat belt buckle switches.
  • Front seat track position sensor.
  • Airbag diagnostic control unit.
  • Crash and rollover sensors.
  • Airbag wiring harness.
  • Airbag status indicator.
