service INFINITI Q50 2018 Owner's Manual

Your INFINITI represents a new way of
thinking about vehicle design. It integrates
advanced engineering and superior crafts-
manship with a simple, refined aesthetic
sensitivity associated with traditional Japa-
nese culture.
The result is a different notion of luxury and
beauty. The car itself is important, but so is
the sense of harmony that the vehicle evokes
in its driver, and the sense of satisfaction you
feel with the INFINITI — from the way it
looks and drives to the high level of retailer
service.
To ensure that you enjoy your INFINITI to
the fullest, we encourage you to read this
Owner’s Manual immediately. It explains all
of the features, controls and performance
characteristics of your INFINITI; it also
provides important instructions and safety
information.
A separate Warranty Information Booklet
is included in your Owner’s literature port-
folio. Always carry it with you when you
take your vehicle to an INFINITI retailer.
The Warranty Information Booklet con-
tents provide complete information about
all warranties covering this vehicle, the
requirements to keep the warranties in
effect as well as the INFINITI Roadside
Assistance program.
Additionally, a separate Customer Care andLemon Law Information Booklet will ex-
plain how to resolve any concerns you may
have with your vehicle, as well as clarify
your rights under your state’s lemon law.
In addition to factory installed options, your
vehicle may also be equipped with additional
accessories installed by INFINITI or by your
INFINITI retailer prior to delivery. It is
important that you familiarize yourself with
all disclosures, warnings, cautions and in-
structions concerning proper use of such
accessories prior to operating the vehicle
and/or accessory. It is recommended you
see an INFINITI retailer for details concern-
ing the particular accessories with which
your vehicle is equipped.READ FIRST — THEN DRIVE

WARNING
.Every person who drives or rides in
this vehicle should use a seat belt at
all times. Children should be properly
restrained in the rear seat and, if
appropriate, in a child restraint.
. The seat belt should be properly
adjusted to a snug fit. Failure to do
so may reduce the effectiveness of
the entire restraint system and in-
crease the chance or severity of injury
in an accident. Serious injury or death
can occur if the seat belt is not worn
properly.
. Always route the shoulder belt over
your shoulder and across your chest.
Never run the belt behind your back,
under your arm or across your neck.
The belt should be away from your
face and neck, but not falling off your
shoulder.
. Position the lap belt as low and snug
as possible AROUND THE HIPS, NOT
THE WAIST. A lap belt worn too high
could increase the risk of internal
injuries in an accident.
. Be sure the seat belt tongue is
securely fastened to the proper
buckle. .
Do not wear the seat belt inside out
or twisted. Doing so may reduce its
effectiveness.
. Do not allow more than one person to
use the same seat belt.
. Never carry more people in the ve-
hicle than there are seat belts.
. If the seat belt warning light glows
continuously while the ignition is
turned ON with all doors closed and
all seat belts fastened, it may indicate
a malfunction in the system. Have the
system checked. It is recommended
you visit an INFINITI retailer for this
service.
. No changes should be made to the
seat belt system. For example, do not
modify the seat belt, add material or
install devices that may change the
seat belt routing or tension. Doing so
may affect the operation of the seat
belt system. Modifying or tampering
with the seat belt system may result
in serious personal injury.
. Once a seat belt pretensioner has
activated, it cannot be reused and
must be replaced together with the
retractor. It is recommended you visit
an INFINITI retailer for this service.
Safety — Seats, seat belts and supplemental restraint system1-13

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.

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.

Center of rear seat
The center seat belt buckle is identified by
the CENTER mark. The center seat belt
tongue can be fastened onlyinto the center
seat belt.

Anchor points are located on the rear parcel
shelf.
If you have any questions when installing a
top tether strap child restraint on the rear
seat, it is recommended you visit an
INFINITI retailer for this service.
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 orequipment to the vehicle. Doing so could

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.
Follow these steps to install a rear-facing
child restraint using the LATCH system:

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).

Precautions on booster seats
WARNING
If a booster seat and seat belt are not
used properly, the risk of a child being
injured or killed in a sudden stop or
collision greatly increases:
. Make sure the shoulder portion of
the belt is away from the child’s face
and neck and the lap portion of the
belt does not cross the stomach.
. Make sure the shoulder belt is not
behind the child or under the child’s
arm.
. A booster seat must only be installed
in a seating position that has a lap/
shoulder belt.
LRS0455
Booster seats of various sizes are offered by
several manufacturers. When selecting any
booster seat, keep the following points in
mind:
.Choose only a booster seat with a label
certifying that it complies with Federal
Motor Vehicle Safety Standard 213 or
Canadian Motor Vehicle Safety Stan-
dard 213.
. Check the booster seat in your vehicle to
be sure it is compatible with the vehicle’s
seat and seat belt system.
