2018 INFINITI Q50 Owner's Manual

1-14Safety — Seats, seat belts and supplemental restraint system
.All seat belt assemblies, including
retractors and attaching hardware,
should be inspected after any colli-
sion. It is recommended you visit an
INFINITI retailer for this service.
INFINITI recommends that all seat
belt assemblies in use during a colli-
sion be replaced unless the collision
was minor and the belts show no
damage and continue to operate
properly. Seat belt assemblies not in
use during a collision should also be
inspected and replaced if either da-
mage or improper operation is noted.
. All child restraints and attaching
hardware should be inspected after
any collision. Always follow the re-
straint manufacturer’s inspection in-
structions and replacement
recommendations. The child re-
straints should be replaced if they
are damaged.
PREGNANT WOMEN
INFINITI recommends that pregnant women
use seat belts. The seat belt should be worn
snug, and always position the lap belt as low
as possible around the hips, not the waist,
and place the shoulder belt over your
shoulder and across your chest. Never run
the lap/shoulder belt over your abdominal area. Contact your doctor for specific re-
commendations.
INJURED PERSONS
INFINITI recommends that injured persons
use seat belts, depending on the injury.
Check with your doctor for specific recom-
mendations.
PRE-CRASH SEAT BELTS WITH
COMFORT FUNCTION (front
seats) (if so equipped)
The pre-crash seat belt tightens the seat belt
with a motor to help restrain front seat
occupants. This helps reduce the risk of
injury in a collision.
The motor retracts the seat belt under the
following emergency conditions:
.
During emergency braking.
. During sudden steering maneuvers.
. Activation of the Forward Emergency
Braking (FEB) system. (See “Forward
Emergency Braking (FEB)” (P.5-105).)
The pre-crash seat belt will not be active
when:
. The seat belt is not fastened.
. The vehicle speed is under 10 MPH (15
km/h) during emergency braking.
. The vehicle speed is under 19 MPH (30
km/h) during sudden steering maneu- vers.
The pre-crash seat belt will not be active
when the brake pedal is not depressed
except when sudden steering maneuvers
occur or the FEB system activates.
The motor also retracts the seat belt when
the seat belt is fastened or unfastened.
When the seat belt is fastened, the motor
tightens the seat belt for a snug fit. When
the seat belt is unfastened, the motor
retracts the seat belt. If the seat belt is not
fully retracted, the motor retracts the seat
belt when the door is opened.
Always wear your seat belt correctly and sit
upright and well back.
If the motor cannot retract the seat belt
when the seat belt is fastened or unfas-
tened, it may indicate the pre-crash seat belt
system has a malfunction. It is recommended
you have an INFINITI retailer check and
repair the system.
When the seat belt is retracted repeatedly in
a short period of time, the motor may not be
able to retract the seat belt. After a few
minutes, the motor normally reactivates and
retracts the seat belt. If the seat belt still
cannot be retracted by the motor, the pre-
crash seat belt system has a malfunction.
Have the system checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.

THREE-POINT TYPE SEAT BELT
WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times.
. Do not ride in a moving vehicle when
the seatback is reclined. This can be
dangerous. The shoulder belt will not
be against your body. In an accident,
you could be thrown into it and
receive neck or other serious injuries.
You could also slide under the lap belt
and receive serious internal injuries.
. For the most effective protection
when the vehicle is in motion, the
seat should be upright. Always sit
well back and upright in the seat with
both feet on the floor and adjust the
seat belt properly.

Models with rear seat folding
WARNING
Do not allow children to play with the
seat belts. Most seating positions are
equipped with Automatic Locking Re-
tractor (ALR) mode seat belts. If the seat
belt becomes wrapped around a child’s
neck with the ALR mode activated, the
child can be seriously injured or killed if
the seat belt retracts and becomes tight.
This can occur even if the vehicle is
parked. Unbuckle the seat belt to release
the child. For the center of the rear seat
on the models with rear seat folding, the
connector tongue
may also be re- leased. Release the connector tongue by
inserting a suitable tool (such as a key)
into the connector buckle
. If the seat
belt can not be unbuckled or is already
unbuckled, release the child by cutting
the seat belt with a suitable tool (such as
a knife or scissors) to release the seat
belt.

Fastening the seat belts
1. Adjust the seat. (See “Seats” (P.1-2).)
2. Slowly pull the seat belt out of theretractor and insert the tongue into the
buckle until you hear and feel the latch
engage.
.The retractor is designed to lockduring a sudden stop or on impact.
A slow pulling motion permits the
belt to move, and allows you some
freedom of movement in the seat.
.If the seat belt cannot be pulled from its fully retracted position, firmly pull
the belt and release it. Then smoothly
pull the belt out of the retractor.
SSS0290
3. Position the lap belt portion low and
snug on the hips as shown.
4. Pull the shoulder belt portion toward the retractor to take up extra slack. Be sure
the shoulder belt is routed over your
shoulder and across your chest.
The three-point type seat belts have two
modes of operation:
. Emergency Locking Retractor (ELR)
. Automatic Locking Retractor (ALR)
The Emergency Locking Retractor (ELR)
mode allows the seat belt to extend and
retract to allow the driver and passengers
some freedom of movement in the seat. The
ELR locks the seat belt when the vehicle
slows down rapidly or during impacts. The Automatic Locking Retractor (ALR)
mode (child restraint mode) locks the seat
belt for child restraint installation.
When the ALR mode is activated the seat
belt cannot be extended again until the seat
belt tongue is detached from the buckle and
fully retracted. The seat belt returns to the
ELR mode after the seat belt fully retracts.
For additional information, see “Child re-
straints” (P.1-23).
The ALR mode should be used only for child
restraint installation. During normal seat
belt use by an occupant, the ALR mode
should not be activated. If it is activated, it
may cause uncomfortable seat belt tension.
WARNING
When fastening the seat belts, be certain
that seatbacks are completely secured in
the latched position. If they are not
completely secured, passengers may be
injured in an accident or sudden stop.

SSS0326
Unfastening the seat belts
To unfasten the seat belt, push the button
on the buckle. The seat belt automatically
retracts.
Checking seat belt operation
Seat belt retractors are designed to lock seat
belt movement by two separate methods:
.When the belt is pulled quickly from the
retractor.
. When the vehicle slows down rapidly.
To increase your confidence in the seat belts,
check the operation as follows:
. Grasp the shoulder belt and pull forward
quickly. The retractor should lock and restrict further belt movement.
If the retractor does not lock during this
check, get the system checked. It is recom-
mended you visit an INFINITI retailer for this
service, or to learn more about seat belt
operation.

Rear center seat belt (models with
rear seat folding)
The rear center seat belt has a seat belt
tongueand a connector tongue. Both
the connector tongue and the seat belt
tongue must be securely latched for proper
seat belt operation.
SSS0241
WARNING
. Always fasten the connector tongue
and the seat belt in the order shown.
. Always make sure both the connector
tongue and the seat belt tongue are
secured when using the seat belt or
installing a child restraint. Do not use
the seat belt or child restraint with
only the seat belt tongue attached.
This could result in serious personal
injury in case of an accident or a
sudden stop.

Stowing rear center seat belt:
When folding down the rear seat, the rear
center seat belt can be retracted into a
stowed position as follows:
1. Hold the connector tongue
so that the
seat belt does not retract suddenly when
the tongue is released from the connec-

tor buckle. Release the connector tongue
by inserting a suitable tool such as key
into the connector buckle.
2. Then secure the connector tongue into the retractor base
.
WARNING
.Do not unfasten the rear center seat
belt connector except when folding
down the rear seat.
. When attaching the rear center seat
belt connector, be certain that the
seatbacks are completely secured in
the latched position and the rear
center seat belt connector is comple-
tely secured.
. If the rear center seat belt connector
and the seatbacks are not secured in
the correct position, serious personal
injury may result in an accident or
sudden stop.

Shoulder belt height adjustment
(front seats)
The shoulder belt anchor height should be
adjusted to the position best for you. (See
“Precautions on seat belt usage” (P.1-12).)
To adjust, push the button
, and then move
the shoulder belt anchor to the desired
position, so that the belt passes over the
center of the shoulder. The belt should be
away from your face and neck, but not
falling off of your shoulder. Release the
adjustment button to lock the shoulder belt
anchor into position.
WARNING
. After adjustment, release the adjust-
ment button and try to move the
shoulder belt anchor up and down to
make sure it is securely fixed in
position.
. The shoulder belt anchor height
should be adjusted to the position
best for you. Failure to do so may
reduce the effectiveness of the entire
restraint system and increase the
chance or severity of injury in an
accident.
SEAT BELT EXTENDERS
If, because of body size or driving position, it
is not possible to properly fit the lap-
shoulder belt and fasten it, an extender that
is compatible with the installed seat belts is
available that can be purchased. The ex-
tender adds approximately 8 in (200 mm) of
length and may be used for either the driver
or front passenger seating position. It is
recommended you visit an INFINITI retailer
for assistance with purchasing an extender if
an extender is required.
WARNING
.It is recommended only INFINITI seat
belt extenders, made by the same
company which made the original
equipment seat belts, be used with
the INFINITI seat belts.
. Adults and children who can use the
standard seat belt should not use an
extender. Such unnecessary use could
result in serious personal injury in the
event of an accident.
. Never use seat belt extenders to
install child restraints. If the child
restraint is not secured properly, the
child could be seriously injured or
killed in a collision or a sudden stop.
SEAT BELT MAINTENANCE
.To clean the seat belt webbing, apply a
mild soap solution or any solution re-
commended for cleaning upholstery or
carpets. Then, wipe with a cloth and
allow the seat belts to dry in the shade.
Do not allow the seat belts to retract
until they are completely dry.
. If dirt builds up in the shoulder belt guide
of the seat belt anchors, the seat belts
may retract slowly. Wipe the shoulder

belt guide with a clean, dry cloth.
. Periodically check to see that the seat
belt and the metal components such as
buckles, tongues, retractors, flexible
wires and anchors work properly. If loose
parts, deterioration, cuts or other da-
mage on the webbing is found, the entire
seat belt assembly should be replaced.

the child. For the center of the rear seat
on the models with rear seat folding, the
connector tongue
may also be re- leased. Release the connector tongue by
inserting a suitable tool (such as a key)
into the connector buckle
. If the seat
belt can not be unbuckled or is already
unbuckled, release the child by cutting
the seat belt with a suitable tool (such as
a knife or scissors) to release the seat
belt.
Children need adults to help protect them.
They need to be properly restrained.
In addition to the general information in this
manual, child safety information is available
from many other sources, including doctors,
teachers, government traffic safety offices,
and community organizations. Every child is
different, so be sure to learn the best way to
transport your child.
There are three basic types of child restraint
systems:
. Rear-facing child restraint
. Forward-facing child restraint
. Booster seat
The proper restraint depends on the child’s
size. Generally, infants up to about 1 year
and less than 20 lbs (9 kg) should be placed
in rear-facing child restraints. Forward-
facing child restraints are available for
children who outgrow rear-facing child re-
straints and are at least 1 year old. Booster
