Light INFINITI Q50 2019 User Guide

The child restraint top tether strap must be
used when installing the child restraint with
the LATCH lower anchor attachments.
First, secure the child restraint with the
LATCH lower anchors (rear outboard seat-
ing positions only).
1. Flip up the anchor cover from the anchorpoint which is located directly behind the
child restraint.
2. If necessary, raise or remove the head restraint or headrest to position the top
tether strap over the top of the seatback.
If the head restraint or headrest is
removed, store it in a secure place. Be
sure to reinstall the head restraint or
headrest when the child restraint is
removed.
See “Head restraints/headrests” (P.1-
8) for head restraint or headrest adjust-
ment, removal and installation informa-
tion.
Position the top tether strap over the top
of the seatback.
3. Secure the tether strap to the tether anchor point on the rear parcel shelf.
4. Refer to the appropriate child restraint installation procedure steps in this sec-
tion before tightening the tether strap.
If you have any questions when installing a
top tether strap, it is recommended you visit an INFINITI retailer for this service.
FORWARD-FACING CHILD RE-
STRAINT INSTALLATION USING
THE SEAT BELTS
WARNING
.
The three-point seat belt with Auto-
matic Locking Retractor (ALR) must
be used when installing a child re-
straint. 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. See “Front passenger air bag
and status light” (P.1-50).
. When installing a child restraint sys-
tem in the rear center position, both
the center seat belt connector tongue
and buckle tongue must be secured
(for models with rear seat folding).
See “Rear center seat belt (models
with rear seat folding)” (P.1-18).

Do not use the lower anchors if the com-
bined 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 vehicle’s seat belt (not the lower an-
chors) to install the child restraint. Be sure to
follow the child restraint manufacturer’s
instructions for installation.

WARNING
Child restraint anchorages are designed
to withstand only those loads imposed
by correctly fitted child restraints. Under
no circumstances are they to be used to
attach adult seat belts, or other items or
equipment to the vehicle. Doing so could
damage the child restraint anchorages.
The child restraint will not be properly
installed using the damaged anchorage,
and a child could be seriously injured or
killed in a collision.

PRECAUTIONS ON SUPPLE-
MENTAL RESTRAINT SYSTEM
This Supplemental Restraint System (SRS)
section contains important information con-
cerning the following systems:
. Driver and passenger front-impact sup-
plemental air bags (INFINITI Advanced
Air Bag System)
. Front seat-mounted side-impact supple-
mental air bag
. Roof-mounted curtain side-impact and
rollover supplemental air bag
. Seat belt with pretensioner
Supplemental front-impact air bag system:
The INFINITI Advanced Air Bag System can
help cushion the impact force to the head
and chest of the driver and front passenger
in certain frontal collisions.
Front seat-mounted side-impact supple-
mental air bag system: This system can help
cushion the impact force to the chest and
pelvis area of the driver and front passenger
in certain side impact collisions. The side air
bag is designed to inflate on the side where
the vehicle is impacted.
Roof-mounted curtain side-impact and roll-
over supplemental air bag system: This
system can help cushion the impact force
to the head of occupants in front and rear
outboard seating positions in certain side impact or rollover collisions. In a side impact,
the curtain air bags are designed to inflate
on the side where the vehicle is impacted. In
a rollover, the curtain air bags on both sides
are designed to inflate and remain inflated
for a short time.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments may cause the curtain air bags to
inflate.
These supplemental restraint systems are
designed to
supplement the crash protection
provided by the driver and passenger seat
belts and are not a substitute for them. Seat
belts should always be correctly worn and
the occupant seated a suitable distance
away from the steering wheel, instrument
panel and door finishers. (See “Seat belts”
(P.1-12) for instructions and precautions on
seat belt usage.)
The supplemental air bags operate only
when the ignition switch is in the ON
position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the systems are operational.

WARNING
.The front air bags ordinarily will not
inflate in the event of a side impact,
rear impact, rollover, or lower sever-
ity frontal collision. Always wear
your seat belts to help reduce the
risk or severity of injury in various
kinds of accidents.
. The front passenger air bag will not
inflate if the passenger air bag status
light is lit. See “Front passenger air
bag and status light” (P.1-50).
. The seat belts and the front air bags
are most effective when you are
sitting well back and upright in the
seat with both feet on the floor. The
front air bags inflate with great
force. Even with the INFINITI Ad-
vanced Air Bag System, if you are
unrestrained, leaning forward, sitting
sideways or out of position in any
way, you are at greater risk of injury
or death in a crash. You may also
receive serious or fatal injuries from
the front air bag if you are up against
it when it inflates. Always sit back
against the seatback and as far-away
as practical from the steering wheel
or instrument panel. Always use the
seat belts.

.The driver and front passenger seat
belt buckles are equipped with sen-
sors that detect if the seat belts are
fastened. The Advanced Air Bag
System monitors the severity of a
collision and seat belt usage then
inflates the air bags as needed. Fail-
ure to properly wear seat belts can
increase the risk or severity of injury
in an accident.
. The front passenger seat is equipped
with occupant classification sensors
(weight sensors) that turn the front
passenger air bag OFF under some
conditions. These sensors are only
used in this seat. Failure to be
properly seated and wearing the seat
belt can increase the risk or severity
of injury in an accident. See “Front
passenger air bag and status light”
(P.1-50).
. Keep hands on the outside of the
steering wheel. Placing them inside
the steering wheel rim could increase
the risk of injury if the front air bag
inflates.

.Make sure that there is no object
placed between the seat cushion and
center console or between the seat
cushion and the door.
. Be sure that the front passenger seat
does not contact the rear seat, in-
strument panel, etc., or the head
restraint does not contact the roof.
. Confirm the operating condition with
the front passenger air bag status
light.
. If you notice that the front passenger
air bag status light is not operating
as described in this section, it is
recommended you visit an INFINITI
retailer to check the passenger seat
Advanced Air Bag System.
. Until you have confirmed with a
retailer that your passenger seat
Advanced Air Bag System is working
properly, position the occupants in
the rear seating positions.
. Do not position the front passenger
seat so it contacts the rear seat. If the
front seat does contact the rear seat,
the air bag system may determine a
sensor malfunction has occurred and
the front passenger air bag status
light may illuminate and the supple-
mental air bag warning light may flash.
This vehicle is equipped with the INFINITI
Advanced Air Bag System for the driver and
front passenger seats. This system is de-
signed to meet certification requirements
under U.S. regulations. It is also permitted in
Canada. All of the information, cautions and
warnings in this manual apply and must be
followed.
The driver supplemental front-impact air
bag is located in the center of the steering
wheel. The front passenger supplemental
front-impact air bag is mounted in the
instrument panel above the glove box. The
front air bags are designed to inflate in
higher severity frontal collisions, although
they may inflate if the forces in another type
of collision are similar to those of a higher
severity frontal impact. They may not inflate
in certain frontal collisions. Vehicle damage
(or lack of it) is not always an indication of
proper front air bag operation.
The INFINITI Advanced Air Bag System has
dual stage air bag inflators. The system
monitors information from the crash zone
sensor, the Air bag Control Unit (ACU), seat
belt buckle switches and the occupant
classification sensors (weight sensors). In-
flator operation is based on the severity of a
collision and seat belt usage for the driver. For the front passenger, the occupant
classification sensors are also monitored.
Based on information from the sensors, only
one front air bag may inflate in a crash,
depending on the crash severity and whether
the front occupants are belted or unbelted.
Additionally, the front passenger air bag
may be automatically turned OFF under
some conditions, depending on the informa-
tion provided by the occupant classification
sensors. If the front passenger air bag is
OFF, the front passenger air bag status light
will be illuminated. (See “Front passenger air
bag and status light” (P.1-50) for further
details.) One front air bag inflating does not
indicate improper performance of the sys-
tem.
If you have any questions about your air bag
system, it is recommended you visit an
INFINITI retailer to obtain information
about the system. If you are considering
modification of your vehicle due to a dis-
ability, you may also contact an INFINITI
retailer. Contact information is contained in
the front of this Owner’s Manual.
When a front air bag inflates, a fairly loud
noise may be heard, followed by release of
smoke. 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.
Safety — Seats, seat belts and supplemental restraint system1-49

1-50Safety — Seats, seat belts and supplemental restraint system
Front air bags, along with the use of seat
belts, help to cushion the impact force on the
head and chest of the front occupants. They
can help save lives and reduce serious
injuries. However, an inflating front air bag
may cause facial abrasions or other injuries.
Front air bags do not provide restraint to the
lower body.
Even with INFINITI advanced air bags, seat
belts should be correctly worn and the driver
and passenger seated upright as far as
practical away from the steering wheel or
instrument panel. The front air bags inflate
quickly in order to help protect the front
occupants. Because of this, the force of the
front air bag inflating can increase the risk of
injury if the occupant is too close to, or is
against, the air bag module during inflation.
The front air bags deflate quickly after a
collision.
The front air bags operate only when the
ignition switch is in the ON position.
After pushing the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.

Front passenger air bag and status
light
WARNING
The front passenger air bag is designed
to automatically turn OFF under some
conditions. Read this section carefully to
learn how it operates. Proper use of the
seat, seat belt and child restraints is
necessary for most effective protection.
Failure to follow all instructions in this
manual concerning the use of seats, seat
belts and child restraints can increase
the risk or severity of injury in anaccident.

Status light:
The front passenger seat is equipped with an
occupant classification sensors (weight sen-
sors) that turn the front passenger air bag on
or off depending on the weight applied to
the front passenger seat. The status of the
front passenger air bag (ON or OFF) is
indicated by the front passenger air bag
status light
which is located on the
instrument panel.
After the ignition switch is placed in the ON
position, the front passenger air bag status
light illuminates for about 7 seconds and
then turns off or remains illuminated de-
pending on the front passenger seat occu-
pied status. The light operates as follows:

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.1-23)
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
