2021 INFINITI QX50 child seat

The pretensioner system may activate with
the supplemental air bag system in certain
types of collisions. Working with the seat belt
retractor, the pretensioner(s) help tighten the
seat belt when the vehicle becomes involved
in certain types of collisions, helping to re-
strain front seat occupants.
The pretensioner(s) are encased within the
seat belt retractor and to the seat belt anchor
affixed to the floor of the vehicle. These seat
belts are used the same way as conventional
seat belts.
When pretensioner(s) activate, smoke is re-
leased and a loud noise may be heard. This
smoke is not harmful and does not indicate a
fire. Care should be taken not to inhale it, as it
may cause irritation and choking. Those with
a history of a breathing condition should get
fresh air promptly.
After the pretensioner(s’) activation, load lim-
iters allow the seat belt to release webbing (if
necessary) to reduce forces against the chest.The supplemental air bag warning lightis used to indicate malfunctions in the preten-
sioner system. For additional information,
see "Supplemental air bag warning light"
(P. 1-61). If the operation of the supplemental
air bag warning light indicates there is a mal-
function, have the system checked. It is rec-
ommended that you visit an INFINITI retailer
for this service.
When selling your vehicle, we request that
you inform the buyer about the pretensioner
system and guide the buyer to the appropri-
ate sections in this Owner's Manual.
SUPPLEMENTAL AIR BAG
WARNING LABELS

front-impact air bag systems are placed in
the vehicle as shown in the illustration.
WARNING
Do not use a rear-facing child restraint on a

WARNING
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
• Use suitable ropes and hooks to secure
cargo.
• Never allow anyone to ride in the lug-
gage area. It is extremely dangerous to
ride in a cargo area inside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
• The child restraint top tether strap may
be damaged by contact with items in the
cargo area. Secure any items in the cargo
area. Your child could be seriously injured
or killed in a collision if the top tether
strap is damaged.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
COAT HOOKS
The coat hooks, located on the rear assist
grips, may be used to store coats and other
articles of clothing.
CAUTION
Do not apply a total load of more than 7.3
lbs. (3.3 kg) to the side pillar coat hook or
33 lbs. (15 kg) to the rear assist grip coat
hook.
ROOF RACK (if so equipped)
WARNING
• Always install the crossbars onto the
roof side rails before loading cargo of
any kind. Loading cargo directly onto the
roof side rails or the vehicle’s roof may
cause vehicle damage.
• Roof rack cross bars should be evenly
distributed.
• Do not exceed maximum roof rack cross-
bars load capacity and always distribute
the load uniformly.

CARGO COVER (if so equipped)
WARNING
• Do not place objects on the cargo cover
while the vehicle is parked or in motion,
no matter how small. The object on the
cargo cover could cause an injury in an
accident or sudden stop, and/or the
cargo cover can become damaged.
• Do not leave the cargo cover in the ve-
hicle with it disengaged from the holder.
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury. •
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

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 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
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.
LOCKING WITH KEY
To lock or unlock the driver’s door, turn the
key toward the front of the vehicle
O1.
To unlock the driver’s door, turn the key to-
ward the rear of the vehicle
O3, then return it
to the neutral position
O2.

WARNING
• Do not leave children or adults who
would normally require the assistance of
others alone in your vehicle. Pets should
also not be left alone. They could acci-
dentally injure themselves or others
through inadvertent operation of the
vehicle. Also, on hot, sunny days, tem-
peratures in a closed vehicle could
quickly become high enough to cause se-
vere or possibly fatal injuries to people or
animals.
• Properly secure all cargo with ropes or
straps to help prevent it from sliding or
shifting. Do not place cargo higher than
the seatbacks. In a sudden stop or colli-
sion, unsecured cargo could cause per-
sonal injury.
EXHAUST GAS (carbon monoxide)
WARNING
• Do not breathe exhaust gases; they con-
tain colorless and odorless carbon mon-
oxide. Carbon monoxide is dangerous. It
can cause unconsciousness or death. •
If you suspect that exhaust fumes are
entering the vehicle, drive with all win-
dows fully open, and have the vehicle in-
spected 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 rear vent windows, liftgates,
doors and trunk lids (if so equipped)
closed while driving, otherwise exhaust
gases could be drawn into the passenger
compartment. If you must drive with one
of these open, follow these precautions:
1. Open all the windows.
2. Set the
air recirculation button
to off and the fan control dial to high
to circulate the air.
• If electrical wiring or other cable connec-
tions must pass to a trailer through the
seal on the liftgate 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 when-
ever:
a. The vehicle is raised for service. b. You suspect that exhaust fumes are
entering into the passenger
compartment.
c. You notice a change in the sound of the exhaust system.
d. You have had an accident involving damage to the exhaust system, un-
derbody, or rear of the vehicle.
THREE-WAY CATALYST
The three-way catalyst is an emission control
device installed in the exhaust system. Ex-
haust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
• The exhaust gas and the exhaust system
are very hot. Keep people, animals or
flammable materials away from the ex-
haust system components.
• Do not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite and
cause a fire.
PRECAUTIONS WHEN STARTING
AND DRIVING
5-4Starting and driving

seconds. Then place the ignition switch back
in the ON position. The vehicle should return
to its normal operating condition. If it does
not return to its normal operating condition,
have the transmission checked and repaired,
if necessary. It is recommended that you visit
an INFINITI retailer for this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of
a collision. Be especially careful when driv-
ing. If necessary, pull to the side of the road
at a safe place and allow the transmission
to return to normal operation, or have it
repaired if necessary.
WARNING
• Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
• Do not release the parking brake from
outside the vehicle.
• Do not use the shift lever in place of the
parking brake. When parking, be sure the
parking brake is fully engaged. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside 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 electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake will apply auto-
matically if the ignition switch is placed in the
OFF position when the brake force is main-
tained by the automatic brake hold function.
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.
The driver’s seat belt needs to be fastened.
