2023 INFINITI QX50 child lock

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 nec-
essary, or put the restraint in another seat
and test it again. You may need to try a
different child restraint. Not all child re-
straints fit in all types of vehicles. 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
see “Front passenger air bag and status
light” (P. 1-52). Move the child restraint
to another seating position. Have the
system checked. It is recommended 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.

Booster seat installation
WARNING
To avoid injury to child, do not use the lap/
shoulder belt in the Automatic Locking Re-
tractor (ALR) mode when using a booster
seat with the seat belts.
For additional information, see “Child safety”
(P. 1-20), “Child restraints” (P. 1-22) and
“Booster seats” (P. 1-38) 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 rearmost
position.
2. Position the booster seat on the seat. Only place it in a front-facing direction.
Always follow the booster seat manufac-
turer’s instructions. 3. The booster seat should be positioned on
the vehicle seat so that it is stable.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct
booster seat fit. If the head restraint/
headrest is removed, store it in a secure
place. Be sure to reinstall the head
restraint/headrest when the booster
seat is removed. For additional informa-
tion, see “Head restraints/headrests”
(P. 1-7).

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 occupyingthe front passenger seat:
• Occupant is a small adult — the air bag light is functioning as intended. The front pas-
senger air bag and front passenger supple-
mental knee air bag are suppressed. However, if the occupant is not a small adult,
then this may be due to the following condi-
tions that may be interfering with the weight
sensors:
• Occupant is not sitting upright, leaning
against the seatback, and centered on the
seat cushion with his/her feet comfortably
extended to the floor.
• A child restraint or other object pressing 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 seatback against 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 between 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 ve-
hicle 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 recom-
mended that 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 pas-
senger seat.
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
• Small adult or child is not sitting upright, leaning against the seatback, and centered
on the seat cushion with his/her feet com-
fortably extended to the floor.
• The child restraint is not properly installed, as outlined in the “Child Restraints”
(P. 1-22) section of this manual.
• An object weighing over 9.1 lbs. (4 kg) hanging on the seat or placed in the seat-
back pocket.
• A child restraint or other object pressing 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 seatback against an object on the seat or floor behind it.

•Properly secure cargo and do not allow it
to contact the top tether strap when it is
attached to the top tether anchor. Cargo
that is not properly secured or cargo that
contacts the top tether strap may dam-
age the top tether strap during a colli-
sion. If the cargo cover contacts the top
tether strap when it is attached to the
top tether anchor, remove the cargo
cover from the vehicle or secure it on the
cargo floor below its attachment loca-
tion. If the cargo cover is not removed, it
may damage the top tether strap during
a collision. Your child could be seriously
injured or killed in a collision if the child
restraint top tether strap is damaged.
The cargo cover keeps the luggage compart-
ment contents hidden from the outside.
To close the cargo cover, remove the cover
from the grooves
O1and retract.
To open the cargo cover, extend the cover
into the grooves
O1to lock into place.
POWER WINDOWS
WARNING
• Make sure that all passengers have their
hands, etc., inside the vehicle while it is in
motion and before closing the windows.
Use the window lock switch to prevent
unexpected use of the power windows.
• To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.
The power windows operate when the igni-
tion switch is placed in the ON position or
for a period of time after the ignition switch
is placed in the OFF position. If the driver's
or passenger's door is opened during this
period of time, the power to the windows is
canceled.

INFINITI VEHICLE IMMOBILIZER
SYSTEM KEYS
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 virtual key accessories (if so equipped)
will also have to be registered. Any key that is
not given to the retailer at the time of regis-
tration 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
water. This could affect system function. When the doors are locked using one of the
following methods, the doors cannot be
opened using the inside or 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 or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people and pets.
DOORS
3-4Pre-driving checks and adjustments

Lockout protection
When any door is open and the power door
lock switch is moved to the lock position, all
doors will lock. If the Intelligent Key is left in
the vehicle after all the doors are closed, all
doors will unlock automatically and a chime
will sound.
These functions help to prevent the Intelli-
gent Key from being accidentally locked in-
side the vehicle.
AUTOMATIC DOOR LOCKS
• All doors lock automatically when the ve-hicle speed reaches 15 mph (24 km/h).
• All doors unlock automatically when the transmission is placed in the P (Park) posi-
tion or when the ignition switch is placed in
the OFF position depending on the option
selected in the “Comfort & Convenience”
options of the “Settings” menu.
NOTE:
The Auto unlock features can be changed
using “Comfort & Convenience” options in
the “Settings” menu of the lower touch-
screen display. For additional information,
refer to the separate INFINITI InTouch®
Owner’s Manual.
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 communi-
cation systems. Do not operate the Intel-
ligent Key while on an airplane. Make
sure the buttons are not operated unin-
tentionally 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.

4. Loosen the oil filter with an oil filter wrench by turning it counterclockwise.
Remove the oil filter by turning it by hand.
5. Wipe the engine oil filter mounting sur- face with a clean rag.
CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the en-
gine. Failure to do so could lead to an oil
leak and engine damage. •
The dipstick must be inserted in place to
prevent oil spillage from the dipstick hole
when filling the engine with oil.
6. Coat the gasket on the new filter with clean engine oil.
7. Screw in the oil filter clockwise until a slight resistance is felt, then tighten addi-
tionally more than 2/3 turn.
Oil filter tightening torque: 11 to 15 ft-lb (14.7 to 20.6 N·m)
8. Clean and re-install the drain plug with a new washer. Securely tighten the drain
plug with a wrench. Do not use excessive
force.
Drain plug tightening torque: 22 to 29 ft-lb (29.4 to 39.2 N·m)

the oil filler cap securely.
For additional information about drain and
refill capacity, see “Recommended fluids/
lubricants and capacities” (P. 10-2). The drain
and refill capacity depends on the oil tem-
perature and drain time. Use these specifica-
tions for reference only. Always use the dip-
stick to determine the proper amount of oil in
the engine.
