INFINITI Q50-HYBRID 2018 Owners Manual

HYBRID
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 and
Lemon 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

Hybrid System-2Hybrid System Overview
The INFINITI Direct Response Hybrid®Sys-
tem combines the power of a gasoline
engine and an electric motor to help mini-
mize fuel consumption and emissions.
Depending on driving conditions, the vehicle
runs on a combination of the gasoline engine
and the electric motor, whichever is best for
those conditions.
Because the gasoline engine charges the
Lithium-ion (Li-ion) battery as needed, the
battery does not have to be charged from an
outside source like an all-electric vehicle.
WARNING
Your vehicle contains a sealed Lithium
ion (Li-ion) high voltage battery. If the
Li-ion battery is disposed of improperly,
there is a risk of severe burns and
electrical shock that may result in ser-
ious injury or death and there is also a
risk of environmental damage.
CAUTION
. Do not misuse the Li-ion battery.
. Do not use the Li-ion battery for any
other purpose.
The Li-ion battery is used to drive the
electric motors in the INFINITI Direct Re-
sponse Hybrid
®System.
The Li-ion battery has a limited service life. It
is recommended that you contact your
INFINITI retailer for information about re-
cycling or disposal of the battery.
WARNING
. The INFINITI Direct Response Hy-
brid®System uses high voltage up to
approximately 408 volts. The system
can be hot during and after starting.
Be careful of both the high voltage
and the high temperature. Obey the
warning labels attached to the vehi-
cle.
. Never disassemble, remove or replace
high-voltage parts and harnesses as
well as their connectors. Doing so can
cause severe burns or electric shock
that may result in serious injury or
death. High-voltage harnesses are
colored orange. The vehicle high
voltage system has no user service-
able parts. It is recommended that
you take your vehicle to an INFINITI
retailer for any necessary mainte-
nance.
. Never try to remove the service plug
located in the trunk. The service plug
is used only when the vehicle is
serviced by trained technicians wear-
ing personal protection equipment
and is part of the high voltage
system. Touching the service plug
can cause severe burns or electric
shock that may result in serious injury

or death.WARNING
In case of a collision:
.If your vehicle is drivable, pull your
vehicle off the road, put the trans-
mission in the P (Park) position, apply
the parking brake and turn the
INFINITI Direct Response Hybrid
®
System off.
. Check to see if there are exposed high
voltage parts and cables. Never touch
the parts and cables. For their loca-
tions, see “High voltage components”
(P.Hybrid System-10). To avoid per-
sonal injury, never touch high-vol-
tage wiring, connectors, and other
high-voltage parts, such as electric
motor inverter and Lithium ion (Li-
ion) battery. An electric shock may
occur if exposed electric wires are
visible when viewed from inside or
outside of your vehicle. Therefore,
never touch exposed electric wires.
. If the vehicle receives a strong impact
to the floor while driving, stop the
vehicle in a safe location and check
the floor.
. Inspect the ground under the vehicle.
If liquid has leaked onto the ground,
the fuel system may have been da- maged. Leave the vehicle as soon as
possible.
. Leaks or damage to the Li-ion bat-
tery may result in a fire. If you
discover them, contact emergency
services immediately. Since the fluid
leak may be lithium organic electro-
lyte from the Li-ion battery, never
touch the fluid leak inside or outside
the vehicle. If the fluid contacts your
skin or eyes, wash it off immediately
with a large amount of water and
receive immediate medical attention
to help avoid serious injury.
. If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result
in serious injury or death from elec-
trical shock.
. If you are not able to safely assess
the vehicle due to vehicle damage, do
not touch the vehicle. Leave the
vehicle and contact emergency ser-
vices. Advise 1st responders that this
is a hybrid vehicle.
. In the event of an accident that
requires body repair and painting, it
is recommended that the vehicle be
