INFINITI Q70 2019 Repair Manual

1-40Safety — Seats, seat belts and supplemental restraint system
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 an occupant classification sen-
sor (pattern sensor) that turns the
front passenger air bag OFF under
some conditions. This sensor is 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.1-46).
. 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.

them in your lap or arms. Some
examples of dangerous riding posi-
tions are shown in the illustrations.
. Children may be severely injured or
killed when the front air bags, side air
bags or curtain air bags inflate if they
are not properly restrained. Pre-
teens and children should be properly
restrained in the rear seat, if possible.
. Even with the INFINITI Advanced Air
Bag System, never install a rear-
facing child restraint in the front
seat. An inflating front air bag could
seriously injure or kill your child. See
“Child restraints” (P.1-19) for details.

WARNING
Front seat-mounted side-impact supple-
mental air bags and roof-mounted cur-
tain side-impact and rollover
supplemental air bags:
.The side air bags ordinarily will not
inflate in the event of a frontal
impact, rear impact, rollover or lower
severity side collision. Always wear
your seat belts to help reduce the risk
or severity of injury in various kinds
of accidents.
. The curtain air bags ordinarily will
not inflate in the event of a front impact, rear impact, or lower severity
side collision. Always wear your seat
belts to help reduce the risk or
severity of injury in various kinds of
accidents.
. The seat belts, side air bags and
curtain air bags are most effective
when you are sitting well back and
upright in the seat. The side air bag
and curtain air bag inflate with great
force. Do not allow anyone to place
their hand, leg or face near the side
air bag on the side of the seatback of
the front seat or near the side roof
rails. Do not allow anyone sitting in
the front seats or rear outboard seats
to extend their hand out of the
window or lean against the door.
Some examples of dangerous riding
positions are shown in the previous
illustrations.
. When sitting in the rear seat, do not
hold onto the seatback of the front
seat. If the supplemental side air bag
inflates, you may be seriously injured.
Be especially careful with children,
who should always be properly re-
strained. Some examples of danger-
ous riding positions are shown in the
illustrations.

.Do not use seat covers on the front
seatbacks. They may interfere with
supplemental side air bag inflation.

INFINITI ADVANCED AIR BAG
SYSTEM (front seats)
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 sensor (pattern sensor). Infla-
tor operation is based on the severity of a
collision and seat belt usage for the driver.
For the front passenger, the occupant
classification sensor is 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
sensor. If the front passenger air bag is OFF,
the front passenger air bag status light will
be illuminated (if the seat is unoccupied, the
light will not be illuminated, but the air bag
will be off). (See “Front passenger air bag
and status light” (P.1-46) for further details.)
One front air bag inflating does not indicate
improper performance of the system.
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 loudnoise 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.
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 supplemental 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 status light
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 increasethe risk or severity of injury in an
accident.
Status light:
The front passenger air bag status light
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 illuminates depending on the
front passenger seat occupied status. The
light operates as follows:
. Unoccupied passenger seat: The
light is OFF and the front passenger air
bag is OFF and will not inflate in a crash.
. Passenger seat occupied by a small adult,
child or child restraint as outlined in this
section: The
light illuminates to
indicate that the front passenger air
bag is OFF and will not inflate in a crash.
. Occupied passenger seat and the pas-
senger meets the conditions outlined in
this section: The
light is OFF to
indicate that the front passenger air bag
is operational.
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 as permitted by U.S. regula- tions. 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.
The occupant classification sensor (pattern
sensor) is in the front passenger seat cushion
and is designed to detect an occupant and
objects on the seat. For example, if a child is
in the front passenger seat, the Advanced
Air Bag System is designed to turn the
passenger air bag OFF in accordance with
the regulations. Also, if a child restraint of
the type specified in the regulations is on the
seat, the occupant classification sensor can
detect it 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 does
not sit in the seat properly (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. Failing to properly
secure child restraints and to use the ALR
mode (child restraint mode) may allow the
restraint to tip or move in an accident or
sudden stop. This can also result in the
passenger air bag inflating in a crash instead
of being OFF. (See “Child restraints” (P.1-19)
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 being de-
tected 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 prop-
erly.Using the front passenger air bag status
light, you can monitor when the front
passenger air bag is automatically turned
OFF with the seat occupied. The light will
not illuminate when the front passenger seat
is unoccupied.
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.
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, the sys-
tem may be sensing an unoccupied seat (in
which case the air bag is OFF). YourINFINITI retailer can check that the system
is OFF by using a special tool. However, until
you have confirmed with your 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
passenger seat status. However, if the seat
becomes unoccupied, the front passenger air
bag status light will remain off.
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 will blink. Have the system
checked. It is recommended you visit an
INFINITI retailer for this service.
Other supplemental front-impact
air bag precautions
WARNING
. Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the front air bags inflate.
Safety — Seats, seat belts and supplemental restraint system1-47

1-48Safety — Seats, seat belts and supplemental restraint system
.Do not place objects with sharp edges
on the seat. Also, do not place heavy
objects on the seat that will leave
permanent impressions in the seat.
Such objects can damage the seat or
occupant classification sensor (pat-
tern sensor). This can affect the
operation of the air bag system and
result in serious personal injury.
. Do not use water or acidic cleaners
(hot steam cleaners) on the seat. This
can damage the seat or occupant
classification sensor. This can also
affect the operation of the air bag
system and result in serious personal
injury.
. Immediately after inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
. No unauthorized changes should be
made to any components or wiring of
the air bag system. This is to prevent
accidental inflation of the supple-
mental air bag or damage to the
supplemental air bag system.
. Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end struc-
ture. This could affect proper opera-
tion of the front air bag system. .
Tampering with the air bag system
may result in serious personal injury.
Tampering includes changes to the
steering wheel and the instrument
panel assembly by placing material
over the steering wheel pad and
above the instrument panel or by
installing additional trim material
around the air bag system.
. Modifying or tampering with the
front passenger seat may result in
serious personal injury. For example,
do not change the front seats by
placing material on the seat cushion
or by installing additional trim mate-
rial, such as seat covers, on the seat
that is not specifically designed to
assure proper air bag operation.
Additionally, do not stow any objects
under the front passenger seat or the
seat cushion and seatback. Such
objects may interfere with the proper
operation of the occupant classifica-
tion sensor.
. No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect
the front air bag system. Tampering
with the seat belt system may result
in serious personal injury. .
It is recommended you visit an
INFINITI retailer for work on and
around the front air bag. It is also
recommended you visit an INFINITI
retailer for installation of electrical
equipment. The Supplemental Re-
straint System (SRS) wiring har-
nesses* should not be modified or
disconnected. Unauthorized electrical
test equipment and probing devices
should not be used on the air bag
system.
. A cracked windshield should be re-
placed immediately by a qualified
repair facility. A cracked windshield
could affect the function of the
supplemental air bag system.
* The SRS wiring harness connectors are
yellow and orange for easy identifica-
tion.
When selling your vehicle, we request that
you inform the buyer about the front air bag
system and guide the buyer to the appro-
priate sections in this Owner’s Manual.

FRONT SEAT-MOUNTED SIDE-
IMPACT SUPPLEMENTAL AIR
BAG AND ROOF-MOUNTED
CURTAIN SIDE-IMPACT AND
ROLLOVER SUPPLEMENTAL AIR
BAG SYSTEMS
The side air bags are located in the outside
of the seatback of the front seats. The
curtain air bags are located in the side roof
rails.All of the information, cautions and
warnings in this manual apply and must be
followed. The side air bags and curtain air
bags are designed to inflate in higher
severity side collisions, although they may inflate if the forces in another type of
collision are similar to those of a higher
severity side impact. They are designed to
inflate on the side where the vehicle is
impacted. They may not inflate in certain
side collisions on the side where the vehicle is
impacted.
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.
Vehicle damage (or lack of it) is not always
an indication of proper supplemental side air
bag and curtain side-impact air bag opera-
tion.
When side air bags and curtain air bags
inflate, 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.
Side air bags, along with the use of seat
belts, help to cushion the impact force on the
chest and pelvis of the front occupants.
Curtain air bags help to cushion the impact
force to the head of occupants in the front
and rear outboard seating positions. They
can help save lives and reduce seriousinjuries. However, an inflating side air bag
or curtain air bag may cause abrasions or
other injuries. Side air bags and curtain air
bags do not provide restraint to the lower
body.
The seat belts should be correctly worn and
the driver and passenger seated upright as
far as practical away from the side air bag.
Rear seat passengers should be seated as far
away as practical from the door finishers
and side roof rails. The side air bags and
curtain air bags inflate quickly in order to
help protect the occupants. Because of this,
the force of the side air bags and curtain air
bags inflating can increase the risk of injury if
the occupant is too close to, or is against,
these air bag modules during inflation. In a
rollover, the curtain air bags on both sides
are designed to inflate. Under both side-
impact situations, the curtain air bags will
remain inflated for a short period of time.
The side air bags and curtain 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 air bag warning light
will turn off after about 7 seconds if the
systems are operational.
