2021 INFINITI Q50 sensor

1-54Safety — Seats, seat belts and supplemental restraint system
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, it is re-
commended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check the system status by using a special
tool. However, until you have confirmed
with your retailer that your air bag is work-
ing 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. This is normal system
operation and does not indicate a malfunc-
tion.
If a malfunction occurs in the front passen-
ger air bag system, the supplemental air bag
warning light
, located in the meter and
gauges area of the instrument panel, will be illuminated (blinking or steadily lit). 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.
. Make sure that the front passenger seat
head restraint does not contact the roof
when adjusting the front passenger seat.
Steps
1. Adjust the seat as outlined in “Seats” (P.1-2). 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 in “Seat belts” (P.1-12). Front passenger seat belt
buckle status is monitored by the occu-
pant classification sensor system, and is
used as an input to determine occupancy
status. So, it is highly recommended that
the front passenger fastens his/her seat
belt.
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 generally keeps the classification
locked during driving, so it is important that
you confirm that the front passenger is
properly classified prior to driving. How-
ever, the occupant classification sensor may
recalculate the weight of the occupant
under some conditions (both while driving
and when stopped), so the front passenger
seat occupant should continue to remain
seated as outlined above.

Troubleshooting:
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
.Occupant is a small adult - the air bag
status light is functioning as intended.
The front passenger air bag is sup-
pressed.
However, if the occupant is not a small
adult, then this may be due to the
following conditions that may be inter-
fering with the weight sensors:
.Occupant is not sitting upright, lean- ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the
floor.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling onthe back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the front
passenger seat.
.An object placed between the seat cushion and center console or be-
tween the seat cushion and the door. If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, the
person should be advised not to ride in
the front passenger seat and the vehicle
should be checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
.Small adult or child is not sittingupright, leaning against the seatback,
and centered on the seat cushion with
his/her feet comfortably extended to
the floor.
.The child restraint is not properly
installed as outlined in “Child re-
straints” (P.1-22).
.An object weighing over 9.1 lbs (4 kg) hanging on the seat or placed in the seatback pocket.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling on
the back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the frontpassenger seat.
.An object placed between the seat
cushion and center console.
.The front passenger seat head re-straint contacting the roof.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF after this, the small
adult, child or child restraint should be
repositioned in the rear seat and the
vehicle should be checked by an INFINITI
retailer as soon as possible.
3. If the light is OFF with no front passen- ger and no objects on the front passen-

Other supplemental front-impact
air bag precautions
WARNING
.Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
. Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat.
Such objects can damage the seat or
occupant classification sensors
(weight sensors). This can affect the
operation of the air bag system and
result in serious personal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensors. This can also affect the operation of the air bag
system and result in serious personal
injury.
. Immediately after inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
. No unauthorized changes should be
made to any components or wiring of
the air bag system. This is to prevent
accidental inflation of the supple-
mental air bag or damage to the
supplemental air bag system.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system.
. Tampering with the air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and
above the instrument panel or by
installing additional trim material
around the air bag system.
. Removing or modifying the front
passenger seat may affect the func-
tion of the air bag system and result
in serious personal injury. .
Modifying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that is not specifically designed to
assure proper air bag operation.
Additionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classifica-
tion sensors.
. No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect
the front air bag system. Tampering
with the seat belt system may result
in serious personal injury.
. It is recommended you visit an
INFINITI retailer for work on and
around the front air bag. It is also
recommended you visit an INFINITI
retailer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag

.The supplemental air bag warning light
remains on after approximately 7 sec-
onds.
. The supplemental air bag warning light
flashes intermittently.
. The supplemental air bag warning light
does not come on at all.
Under these conditions, the air bag or
pretensioner systems may not operate prop-
erly. They must be checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.
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 as soon as possible. It is recom-
mended you visit an INFINITI retailer for
this service.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain air
bags and pretensioners are designed to
activate on a one-time-only basis. As a
reminder, unless it is damaged, the supple-
mental air bag warning light will remain
illuminated after inflation has occurred.
These systems should be repaired and/or
replaced as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
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
conducting the maintenance. The ignition
switch should always be 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. It is recommended you visit an INFINITI
retailer for this service. However, the
air bag module and pretensioner
system cannot be repaired.
. The front air bag, side air bag, curtain
air bag and the pretensioner system
should be inspected if there is any
damage to the front end or side
portion of the vehicle. It is recom-
mended you visit an INFINITI retailer
for this service.
. If you need to dispose of the supple-
mental air bag or pretensioner or
scrap the vehicle, it is recommended
you visit an INFINITI retailer. Correct
supplemental air bag and seat belt
pretensioner system disposal proce-
dures are set forth in the appropriate
INFINITI Service Manual. Incorrect
disposal procedures could cause per-
sonal injury.
. If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked by an INFINITI retailer to
verify it is still functioning correctly.
The OCS should be checked even if no
air bags deploy as a result of the
impact. Failure to verify proper OCS
function may result in an improper air
bag deployment resulting in injury or
