2018 INFINITI Q50 Maintenance


2018 OWNER’S MANUAL
AND MAINTENANCE INFORMATION
For your safety, read carefully and keep in this vehicle.

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
SAFELY
Before driving your vehicle, read your Own-
er’s Manual carefully. This will ensure famil-
iarity with controls and maintenance
requirements, assisting you in the safe
operation of your vehicle.

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

1-60Safety — Seats, seat belts and supplemental restraint system
If any of the following conditions occur, the
air bag and/or pretensioner systems need
servicing:
.The supplemental air bag warning light
remains on after approximately 7 sec-
onds.
. The supplemental air bag warning light
flashes intermittently.
. The supplemental air bag warning light
does not come on at all.
Under these conditions, the air bag or
pretensioner systems may not operate prop-
erly. They must be checked and repaired. It is
recommended you visit an INFINITI retailer
for this service.
WARNING
If the supplemental air bag warning light
is on, it could mean that the front air
bag, side air bag, curtain air bag and/or
pretensioner systems will not operate in
an accident. To help avoid injury to
yourself or others, have your vehicle
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for
this service.
REPAIR AND REPLACEMENT
PROCEDURE
The front air bags, side air bags, curtain air
bags and pretensioners are designed to
activate on a one-time-only basis. As a
reminder, unless it is damaged, the supple-
mental air bag warning light will remain
illuminated after inflation has occurred.
These systems should be repaired and/or
replaced as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioners and related
parts should be pointed out to the person
conducting the maintenance. The ignition
switch should always be in the LOCK
position when working under the hood or
inside the vehicle.
WARNING
. Once a front air bag, side air bag, or
curtain air bag has inflated, the air
bag module will not function again
and must be replaced. Additionally,
the activated pretensioner must also
be replaced. The air bag module and
pretensioner should be replaced. It is recommended you visit an INFINITI
retailer for this service. However, the
air bag module and pretensioner
system cannot be repaired.
. The front air bag, side air bag, curtain
air bag and the pretensioner system
should be inspected if there is any
damage to the front end or side
portion of the vehicle. It is recom-
mended you visit an INFINITI retailer
for this service.
. If you need to dispose of the supple-
mental air bag or pretensioner or
scrap the vehicle, it is recommended
you visit an INFINITI retailer. Correct
supplemental air bag and seat belt
pretensioner system disposal proce-
dures are set forth in the appropriate
INFINITI Service Manual. Incorrect
disposal procedures could cause per-
sonal injury.
. If there is an impact to your vehicle
from any direction, your Occupant
Classification Sensor (OCS) should be
checked by an INFINITI retailer to
verify it is still functioning correctly.
The OCS should be checked even if no
air bags deploy as a result of the
impact. Failure to verify proper OCS
function may result in an improper air
bag deployment resulting in injury or
