2021 INFINITI Q50 child seat

In addition to the above, certain objects
placed on the front passenger seat may also
cause the light to operate as described
above depending on their weight.
For additional information related to the
normal operation and troubleshooting of
this occupant classification sensor system,
please refer to “Normal operation” (P.1-54)
and “Troubleshooting” (P.1-55).
Front passenger air bag:
The front passenger air bag is designed to
automatically turn OFF when the vehicle is
operated under some conditions as de-
scribed below in accordance with U.S.
regulations. If the front passenger air bag
is OFF, it will not inflate in a crash. The driver
air bag and other air bags in your vehicle are
not part of this system.
The purpose of the regulation is to help
reduce the risk of injury or death from an
inflating air bag to certain front passenger
seat occupants, such as children, by requiring
the air bag to be automatically turned OFF.
Certain sensors are used to meet the
requirements.
The occupant classification sensor in this
vehicle is a weight sensor. It is designed to
detect an occupant and objects on the seat
by weight. For example, if a child is in the
front passenger seat, the Advanced Air Bag
System is designed to turn the passenger airbag OFF in accordance with the regulations.
Also, if a child restraint of the type specified
in the regulations is on the seat, its weight
and the child’s weight can be detected and
cause the air bag to turn OFF.
Front passenger seat adult occupants who
are properly seated and using the seat belt
as outlined in this manual should not cause
the 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.
INFINITI recommends that pre-teens and
children be properly restrained in a rear seat.
INFINITI also recommends that appropriate
child restraints and booster seats be prop-
erly installed in a rear seat. If this is not
possible, the occupant classification sensor
is designed to operate as described above to
turn the front passenger air bag OFF for
specified child restraints as required by the
regulations. Failing to properly secure child
restraints and to use the ALR mode may
allow the restraint to tip or move in a
collision or sudden stop. This can also result
in the passenger air bag inflating in a crash
instead of being OFF. For additional infor-
mation, refer to “Child restraints” (P.1-22)
for proper use and installation.
If the front passenger seat is not occupied,
the passenger air bag is designed not to
inflate in a crash. However, heavy objects
placed on the seat could result in air bag
inflation, because of the object’s weight
detected by the occupant classification
sensor. Other conditions could also result in
air bag inflation, such as if a child is standing
on the seat, or if two children are on the
seat, contrary to the instructions in this
manual. Always be sure that you and all
vehicle occupants are seated and restrained
properly.
Using the front passenger air bag status
light, you can monitor when the front
passenger air bag is automatically turned
OFF.
If an adult occupant is in the seat but the
front passenger air bag status light is
illuminated (indicating that the air bag is
OFF), it could be that the person is a small
adult, or is not sitting on the seat properly or
not using the seat belt properly.
If a child restraint must be used in the front
seat, the front passenger air bag status light
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, 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-

VALET HAND-OFF
When you have to leave a key with a valet,
give them the Intelligent Key itself and keep
the mechanical key with you to protect your
belongings.
To prevent the glove box and the trunk from
being opened during valet hand-off, follow
the procedures below.
1. Push the trunk release power cancelswitch to the OFF (cancel) side.
2. Remove the mechanical key from the Intelligent Key.
3. Lock the glove box and the trunk pass- through with the mechanical key.
4. Hand the Intelligent Key to the valet, keeping the mechanical key in your
pocket or bag for insertion into the
Intelligent Key when you retrieve your
vehicle.
See “Trunk lid” (P.3-22), “Glove box” (P.2-
50) and “Trunk pass-through” (P.1-7).
WARNING
. Always have the doors locked while
driving. Along with the use of seat
belts, this provides greater safety in
the event of an accident by helping to
prevent persons from being thrown
from the vehicle. This also helps keep
children and others from unintention-
ally opening the doors, and will help
keep out intruders.
. Before opening any door, always look
for and avoid oncoming traffic.
. To help avoid risk of injury or death
through unintended operation of the
vehicle and or its systems, including
entrapment in windows or inadver-
tent door lock activation, do not
leave children, people who require
the assistance of others or pets
unattended in your vehicle. Addition-
ally, the temperature inside a closed
vehicle on a warm day can quickly
become high enough to cause a sig-
nificant risk of injury or death to
people and pets.
SPA2457
LOCKING WITH MECHANICAL
KEY
To lock the driver’s door, turn the driver’s
door key cylinder to the front of the vehicle
.
To unlock the driver’s door, turn the driver’s
door key cylinder to the rear of the vehicle
.
To lock or unlock the other doors and the
trunk lid, use the Intelligent Key function
(one touch unlock sensor, request switch or
UNLOCK button). (See “Intelligent Key sys-
tem” (P.3-6).)
DOORS

5-4Starting and driving
WARNING
.Do not leave children or adults who
would normally require the support
of others alone in your vehicle. Pets
should not be left alone either. They
could accidentally injure themselves
or others through inadvertent opera-
tion of the vehicle. Also, on hot,
sunny days, temperatures in a closed
vehicle could quickly become high
enough to cause severe or possibly
fatal injuries to people or animals.
. Closely supervise children when they
are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
EXHAUST GAS (carbon monoxide)
WARNING
.Do not breathe exhaust gases; they
contain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconsciousness
or death.
. If you suspect that exhaust fumes are
entering the vehicle, drive with all
windows fully open, and have the
vehicle inspected immediately.
. Do not run the engine in closed spaces
such as a garage.
. Do not park the vehicle with the
engine running for any extended
length of time.
. Keep the trunk lid closed while driv-
ing, otherwise exhaust gases could be
drawn into the passenger compart-
ment. If you must drive with the
trunk lid open, follow these precau-
tions:
1) Open all the windows.
2) Set the air recirculation to off and the fan control to high to circulate
the air. .
If electrical wiring or other cable
connections must pass to a trailer
through the seal on the trunk lid or
the body, follow the manufacturer’s
recommendation to prevent carbon
monoxide entry into the vehicle.
. The exhaust system and body should
be inspected by a qualified mechanic
whenever:
— The vehicle is raised for service.
— You suspect that exhaust fumes are entering into the passenger
compartment.
— You notice a change in the sound of the exhaust system.
— You have had an accident invol- ving damage to the exhaust sys-
tem, underbody, or rear of the
vehicle.
