2019 INFINITI QX50 child lock

WARNING
Child restraint anchorages are designed to
withstand only those loads imposed by cor-
rectly fitted child restraints. Under no cir-
cumstances are they to be used to attach
adult seat belts, or other items or equip-
ment to the vehicle. Doing so could damage
the child restraint anchorages. The child re-
straint will not be properly installed using
the damaged anchorage, and a child could
be seriously injured or killed in a collision.
FORWARD-FACING CHILD
RESTRAINT INSTALLATION
USING THE SEAT BELTS
WARNING
The three-point seat belt with Automatic
Locking Retractor (ALR) must be used
when installing a child restraint. Failure to
use the ALR mode will result in the child
restraint not being properly secured. The
restraint could tip over or be loose and
cause injury to a child in a sudden stop or
collision. Also, it can change the operation
of the front passenger air bag. For addi-
tional information, refer to “Front passen-
ger air bag and status light” in this section.For additional information, refer to all Warn-
ings and Cautions in the “Child safety” and
“Child restraints” sections of this manual be-
fore installing a child restraint.
Do not use the lower anchors if the combined
weight of the child and the child restraint
exceeds 65 lbs. (29.5 kg). If the combined
weight of the child and the child restraint is
greater than 65 lbs. (29.5 kg), use the vehi-
cle’s seat belt (not the lower anchors) to in-
stall the child restraint. Be sure to follow the
child restraint manufacturer’s instructions for
installation. Follow these steps to install a forward-
facing child restraint using the vehicle seat
belt in the rear seats or in the front passenger
seat:
1. If you must install a child restraint in the
front seat, it should be placed in a
forward-facing direction only. Move
the seat to the rearmost position. Child
restraints for infants must be used in the
rear-facing direction and, therefore,
must not be used in the front seat.
2. Position the child restraint on the seat. Always follow the child restraint manu-
facturer’s instructions.
The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
child restraint fit. If the head
restraint/headrest is removed, store it in
a secure place. Be sure to reinstall the
head restraint/headrest when the child
restraint is removed. For additional in-
formation, refer to “Head
restraints/headrests” in this section.

8. After attaching the child restraint, test itbefore you place the child in it. Push it
from side to side while holding the child
restraint near the seat belt path. The
child restraint should not move more
than 1 inch (25 mm), from side to side.
Try to tug it forward and check to see if
the belt holds the restraint in place. If the
restraint is not secure, tighten the seat
belt as necessary, or put the restraint in
another seat and test it again. You may
need to try a different child restraint. Not
all child restraints fit in all types of ve-
hicles. 9. Check to make sure the child restraint is
properly secured prior to each use. If the
seat belt is not locked, repeat steps 2
through 8.
10. If the child restraint is installed in thefront passenger seat, place the ignition
switch in the ON position. The front pas-
senger air bag status light
should
illuminate. If this light is not illuminated
refer to “Front passenger air bag and
status light” in this section. Move the
child restraint to another seating posi-
tion. Have the system checked. It is rec-
ommended that you visit an INFINITI
retailer for this service.
After the child restraint is removed and the
seat belt is fully retracted, the ALR mode
(child restraint mode) is canceled.

∙ Make sure the child’s head will be prop-erly supported by the booster seat or ve-
hicle seat. The seatback must be at or
above the center of the child’s ears. For
example, if a low back booster seat is
chosen, the vehicle seatback must be at
or above the center of the child’s ears. If
the seatback is lower than the center of
the child’s ears, a high back booster seat
should be used. ∙ If the booster seat is compatible with
your vehicle, place the child in the booster
seat and check the various adjustments
to be sure the booster seat is compatible
with the child. Always follow all recom-
mended procedures.
All U.S. states and Canadian provinces or
territories require that infants and small
children be restrained in an approved child
restraint at all times while the vehicle is be-
ing operated.
The instructions in this section apply to
booster seat installation in the rear seats or
the front passenger seat.Booster seat installation
WARNING
To avoid injury to child, do not use the
lap/shoulder belt in the Automatic Locking
Retractor (ALR) mode when using a
booster seat with the seat belts.
For additional information, refer to all Warn-
ings and Cautions in the “Child safety,” “Child
restraints” and “Booster seats” sections of
this manual before installing a child restraint.
Follow these steps to install a booster seat in
the rear seats or in the front passenger seat: 1.
If you must install a booster seat in the
front seat, move the seat to the rear-
most position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manu-
facturer’s instructions.

mended that you take your vehicle to an
INFINITI retailer. An INFINITI retailer can
check system status by using a special tool.
However, until you have confirmed with a
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 front
passenger seat status. This is normal system
operation and does not indicate a malfunc-
tion.
If a malfunction occurs in the front passenger
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 that you
visit an INFINITI retailer for this service.
Normal operation
In order for the occupant classification sen-
sor system to classify the front passenger
based on weight, please follow the precau-
tions 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 in the “Seats” section of this manual. Sit upright, lean-
ing against the seatback, and centered
on the seat cushion with your feet com-
fortably extended to the floor.
2. Make sure there are no objects on your lap.
3. Fasten the seat belt as outlined in the “Seat belts” section of this manual. Front
passenger seat belt buckle status is
monitored by the occupant classification
system, and is used as an input to deter-
mine occupancy status. So, it is highly
recommended that the front passenger
fasten their 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. However,
the occupant classification sensor may re-
calculate the weight of the occupant under
some conditions (both while driving and
when stopped), so front passenger seat oc-
cupants 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 occupying the front passenger seat:
∙ Occupant is a small adult — the air bag light is functioning as intended. The front
passenger air bag is suppressed.

INFINITI VEHICLE IMMOBILIZER
SYSTEM KEYS
You can only drive your vehicle using the
Intelligent Keys which are registered to the
INFINITI Vehicle Immobilizer System compo-
nents in your vehicle.
The mechanical key can be used for all the
locks.
Never leave the keys in the vehicle.
Additional or replacement keys:
If you still have a key, the key number is not
necessary when you need extra INFINITI Ve-
hicle Immobilizer System keys. Your existing
key can be duplicated without knowing the
key number. As many as four INFINITI Ve-
hicle Immobilizer System keys can be used
with one vehicle. You should bring all
INFINITI Vehicle Immobilizer System keys
that you have to the INFINITI retailer for
registration. This is because the registration
process will erase the memory of all key
codes previously registered into the INFINITI
Vehicle Immobilizer System. After the regis-
tration process, these components will only
recognize keys coded into the INFINITI Ve-
hicle Immobilizer System during registration.Any key that is not given to the retailer at the
time of registration will no longer be able to
start your vehicle.CAUTION
Do not allow the immobilizer system key,
which contains an electrical transponder,
to come into contact with water or salt wa-
ter. This could affect system function.
When the doors are locked using one of the
following methods, the doors cannot be
opened using the outside door handles. The
doors must be unlocked to open the doors.WARNING
∙ Always have the doors locked while driv-
ing. 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
unintentionally 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 ve-
hicle and/or its systems, including en-
trapment in windows and/or inadver-
tent door lock activation, do not leave
children, people who require the assis-
tance of others and/or pets unattended
in your vehicle. Additionally, the tem-
perature inside a closed vehicle on a
warm day can quickly become high
enough to cause a significant risk of in-
jury or death to people and/or pets.

CHILD SAFETY REAR DOOR
LOCK
Child safety locks help prevent the rear doors
from being opened accidentally, especially
when small children are in the vehicle.
The child safety lock levers are located on the
edge of the rear doors.
When the lever is in the LOCK position, the
door can be opened only from the outside.
WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ The Intelligent Key transmits radio waves when the buttons are pressed. The
FAA advises the radio waves may affect
aircraft navigation and communication
systems. Do not operate the Intelligent
Key while on an airplane. Make sure the
buttons are not operated unintentionally
when the unit is stored for a flight.
∙ Before leaving the vehicle, engage the P (Park) position and check that the elec-
tronic parking brake warning light is illu-
minated to confirm that the electronic
parking brake is applied. The electronic
parking brake warning light will remain
on for a period of time after the driver’s
door is locked. ∙ Make sure to engage the P (Park) posi-
tion and apply the parking brake when
parking your vehicle, riding on or off the
vehicle or loading luggage. Failure to do
so could cause the vehicle to move or roll
away unexpectedly and result in serious
personal injury or property damage.
The Intelligent Key system can operate all the
door locks using the remote control function
or pushing the request switch on the vehicle
without taking the key out from a pocket or
purse. The operating environment and/or
conditions may affect the Intelligent Key sys-
tem operation.
Be sure to read the following before using the
Intelligent Key system.
CAUTION
∙ Be sure to carry the Intelligent Key with you when operating the vehicle.
∙ Never leave the Intelligent Key in the ve- hicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
