1-62Safety — seats, seat belts and supplemental restraint system
may or may not be illuminated, depending on
the size of the child and the type of child
restraint being used. If the front passenger
air bag status light is not illuminated (in-
dicating that the air bag might inflate in a
crash), it could be that the child restraint or
seat belt is not being used properly. Make
sure that the child restraint is installed
properly, the seat belt is used properly and
the occupant is positioned properly. If the
front passenger air bag status light is still not
illuminated, reposition the occupant or child
restraint in a rear seat.
If the front passenger air bag status light will
not illuminate even though you believe that
the child restraint, the seat belts and the
occupant are properly positioned, the sys-
tem may be sensing an unoccupied seat (in
which case the air bag is OFF). Your
INFINITI retailer can check that the system
is OFF by using a special tool. However, until
you have confirmed with your retailer that
your air bag is working properly, reposition
the occupant or child restraint in a rear seat.
The INFINITI Advanced Air Bag System and
front passenger air bag status light will take
a few seconds to register a change in the
passenger seat status. However, if the seat
becomes unoccupied, the front passenger air
bag status light will remain off.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air bagwarning light, located in the meter and
gauges area will blink. Have the system
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation:
In order for the occupant classification
sensor system to classify the front passen-
ger based on weight, please follow the
precautions and steps outlined below:
Precautions:
. Make sure that there are no objects
weighing over 9.1 lbs (4 kg) hanging on
the seat or placed in the seatback pocket.
. Make sure that a child restraint or other
object is not pressing against the rear of
the seatback.
. Make sure that a rear passenger is not
pushing or pulling on the back of the
front passenger seat.
. Make sure that the front passenger seat
or seatback is not forced back against an
object on the seat or floor behind it.
. Make sure that there is no object placed
under the front passenger seat.
Steps:
1. Adjust the seat as outlined. (See “Seats” (P.1-3).) Sit upright, leaning against the
seatback, and centered on the seat
cushion with your feet comfortably ex-
tended to the floor. 2. Make sure there are no objects on your
lap.
3. Fasten the seat belt as outlined. (See “Seat belts” (P.1-18).)
4. Remain in this position for 30 seconds allowing the system to classify the front
passenger before the vehicle is put into
motion.
5. Ensure proper classification by checking the front passenger air bag status light.
NOTE:
This vehicle’s occupant classification sensor
system locks the classification during driv-
ing so it is important that you confirm that
the front passenger is properly classified
prior to driving. Also, the occupant classifi-
cation sensor system may recalculate the
weight of the occupant when the vehicle
comes to a stop (i.e. stop light, stop sign,
etc.), so the front passenger seat occupant
should continue to remain seated as out-
lined above.
Troubleshooting:
If you think the front passenger air bag
status light is incorrect: 1. If the light is ON with no front passenger and no objects on the front
passenger seat:
This may be due to the following conditions
that may be interfering with the weight
