Nissan Sentra Owners Manual: Supplemental air bag warning light

Nissan Sentra Owners Manual / Safety—Seats, seat belts and supplemental restraint system / Supplemental restraint system / Supplemental air bag warning light

The supplemental air bag warning light,

The supplemental air bag warning light, displaying in the instrument panel,
monitors the circuits for the air bag systems, pretensioners and all related wiring.

When the ignition switch is placed in the ON or START position, the supplemental air bag warning light illuminates for about 7 seconds and then turns off. This means the system is operational.

If any of the following conditions occur, the front air bag, side air bag, curtain air bag and pretensioner systems need servicing:

The supplemental air bag warning light remains on after approximately 7 seconds.
The supplemental air bag warning light flashes intermittently.
The supplemental air bag warning light does not come on at all.

Under these conditions, the front air bag, side air bag, curtain air bag or pretensioner systems may not operate properly. They must be checked and repaired. Take your vehicle to the nearest NISSAN dealer.

WARNING

If the supplemental air bag warning light is on, it could mean that the front air bag, side air bag, curtain air bag and/or pretensioner systems will not operate in an accident.

To help avoid injury to yourself or others, have your vehicle checked by a NISSAN dealer as soon as possible.

Repair and replacement procedure

The front air bags, side air bags, curtain air bags and pretensioners are designed to inflate on a one-time-only basis. As a reminder, unless it is damaged, the supplemental air bag warning light remains illuminated after inflation has occurred.

Repair and replacement of these supplemental air bag systems should be done only by a NISSAN dealer.

When maintenance work is required on the vehicle, the front air bags, side air bags, curtain air bags, pretensioners and related parts should be pointed out to the person performing the maintenance.

The ignition switch should always be placed in the LOCK position when working under the hood or inside the vehicle.

WARNING

Once a front air bag, side air bag, or curtain air bag has inflated, the air bag module will not function again and must be replaced. Additionally, the activated pretensioner must also be replaced.
The air bag module and pretensioner should be replaced by a NISSAN dealer. The air bag module and pretensioner cannot be repaired.
The front air bag, side air bag, curtain air bag systems and the pretensioner system should be inspected by a NISSAN dealer if there is any damage to the front end or side portion of the vehicle.
If you need to dispose of the supplemental air bag or pretensioner systems or scrap the vehicle, contact a NISSAN dealer. Incorrect disposal procedures could cause personal injury.
If there is an impact to your vehicle from any direction, your Occupant Detection Sensor (ODS) should be checked by a NISSAN dealer to verify it is still functioning correctly. The ODS should be checked even if no air bags deploy as a result of the impact. Failure to verify proper ODS function may result in an improper air bag deployment resulting in injury or death.

NOTE:

In the event of a crash involving an airbag deployment (side, front or both), the vehicle’s hazard lamps (turn indicators) will activate.
