[SRS Malfunction Service
Required]The restraint system needs servicing. The
warning light also lights up in the combination meter.
It is recommended you visit an INFINITI retailer for these services.
Unless checked and repaired, the Supplemental Restraint Systems and/or the pretensioner seat belt may not function properly.
WARNING
If this light is on, it could mean that the front air bag, side air bag, curtain air bag systems and/or pretensioner systems will not
operate in an accident. To help avoid injury to yourself or others, have your vehicle checked as soon as possible. It is recommended
you visit an INFINITI retailer for this service.

[Front Passenger Airbag
Disabled See Operator's
Manual]The front-passenger front air bag is disabled during the journey although an adult or person of corresponding stature is on the
front passenger seat.
Front passenger seat adult occupants who are properly seated and using the seat belt as outlined in this manual should not cause
the front passenger air bag to be automatically turned OFF. For small adults it may be turned OFF, however if the occupant takes
his/her weight off the seat cushion (for example, by not sitting upright, by sitting on an edge of the seat, or by otherwise being out
of position), this could cause the sensor to turn the air bag OFF. Always be sure to be seated and wearing the seat belt properly for
the most effective protection by the seat belt and supplemental air bag.
If additional forces are applied to the seat, the system may interpret the occupant's weight as lower than it actually is.
1. Stop the vehicle in a safe area away from traffic as soon as possible, paying attention to road and traffic conditions.
2. Secure the vehicle against rolling away.
3. Switch the ignition off.
4. Have the occupant on the front-passenger seat step out of the vehicle.
5. Make sure that the seat is unoccupied, close the front passenger door and switch on the ignition.
6. Observe the indicator lights in the center console and the vehicle information display and check the
following. Seat unoccupied and ignition switched on:
- The and indicator lights must light up simultaneously for
approximately six seconds.
- The indicator lights must then light up and remain lit. If the indicator light is on, the automatic
front-passenger front air bag deactivation system has disabled the front-passenger front air bag (see "Front passenger air bag
and status light")
- the [Front Passenger Airbag Enabled See Operator's Manual] or [Front Passenger Airbag Disabled See Operator's Manual]
display messages must not be shown in the vehicle information display.
7. Wait for a period of at least 60 seconds until the necessary system checks have been completed.
8. Make sure that the display messages do not appear in the vehicle information display.
If these conditions are met, the front-passenger seat can be occupied again. Whether the or
indicator light remains lit or goes out depends on how the automatic front passenger front air bag deactivation system classifies the
occupant.
If, after taking the steps above, you still believe the system is not operating properly, have it checked immediately. It is recommended
you visit an INFINITI retailer for this service.

Enabled See Operator's
Manual]The front-passenger front air bag is enabled during the journey although:
•A child or child restraint as specified in U.S. regulations is located on the front-passenger seat.
or
•The front-passenger seat is not occupied.
The system may detect objects or forces that are adding to the weight applied to the seat.
1. Stop the vehicle in a safe area away from traffic as soon as possible, paying attention to road and traffic conditions.
2. Secure the vehicle against rolling away.
3. Switch the ignition off.
4. Open the front-passenger door.
5. Remove the child and the child restraint system from the front passenger seat.
6. Make sure there are no objects applying additional force to the seat. The system may otherwise detect the additional force and
interpret the seat occupant's weight as greater than it actually is.
7. Make sure that the seat is unoccupied, close the front passenger door and switch on the ignition.
8. Observe the indicator lights in the center console and the vehicle information display and check the
following. Seat unoccupied and ignition switched on:
