2018 INFINITI Q70 HYBRID fuel consumption

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

The distance to empty (dte) mode provides
you with an estimation of the distance that
can be driven before refueling. The dte is
constantly being calculated, based on the
amount of fuel in the fuel tank and the actual
fuel consumption.
The display is updated every 30 seconds.
The dte mode includes a low range warning
feature. If the fuel level is low, the warning is
displayed on the screen.
When the fuel level drops even lower, the
dte display will change to “——”.
.If the amount of fuel added is small, the
display just before the ignition switch is
pushed to the OFF position may con-
tinue to be displayed.
. When driving uphill or rounding curves,
the fuel in the tank shifts, which may
momentarily change the display.
8. Engine coolant temperature
gauge
The gauge indicates the engine coolant
temperature.
This displays the temperature of the engine
coolant. The range of coolant overheat is indicated by the horizontal line of the upper
part of the H mark.
The engine coolant temperature varies with
the outside air temperature and driving
conditions.
CAUTION
If the engine is overheated, continued
operation of the vehicle may seriously
damage the engine. See “If your vehicle
overheats” (P.6-12) for immediate ac-
tion required.
9. Outside air temperature (ICY — °F
or °C)
The outside air temperature is displayed in °F
or °C in the range of −22 to 140°F (−30 to
60°C).
The outside air temperature mode includes a
low temperature warning feature. If the
outside air temperature is below 37°F
(3°C), the warning is displayed on the screen.
The outside temperature sensor is located in
front of the radiator. The sensor may be
affected by road or engine heat, wind
directions and other driving conditions. The
display may differ from the actual outside
temperature or the temperature displayed
on various signs or billboards.

10-4Technical and consumer information
problems and/or fuel system damage.
.The fuel should be unleaded and have an
octane rating no lower than that re-
commended for unleaded gasoline.
. If an oxygenate-blend, excepting a
methanol blend, is used, it should con-
tain no more than 15% oxygenate.
. If a methanol blend is used, it should
contain no more than 5% methanol
(methyl alcohol, wood alcohol). It should
also contain a suitable amount of ap-
propriate cosolvents and corrosion in-
hibitors. If not properly formulated with
appropriate cosolvents and corrosion
inhibitors, such methanol blends may
cause fuel system damage and/or vehi-
cle performance problems. At this time,
sufficient data is not available to ensure
that all methanol blends are suitable for
use in INFINITI vehicles.
If any undesirable driveability problems such
as engine stalling or hard hot starting are
experienced after using oxygenate-blend
fuels, immediately change to a non-oxyge-
nate fuel or a fuel with a low blend of MTBE.
Take care not to spill gasoline during
refueling. Gasoline containing oxygenates
can cause paint damage.E-15 fuel
E-15 fuel is a mixture of approximately 15%
fuel ethanol and 85% unleaded gasoline. E-
15 can only be used in vehicles designed to
run on E-15 fuel. U.S. government regula-
tions require fuel ethanol dispensing pumps
to be identified with small, square, orange
and black label with the common abbrevia-
tion or the appropriate percentage for that
region.
E-85 fuel
E-85 fuel is a mixture of approximately 85%
fuel ethanol and 15% unleaded gasoline. E-
85 can only be used in a Flexible Fuel Vehicle
(FFV). Do not use E-85 fuel in your vehicle.
U.S. government regulations require fuel
ethanol dispensing pumps to be identified
by a small, square, orange and black label
with the common abbreviation or the appro-
priate percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manga-
nese tricarbonyl, is an octane boosting
additive. INFINITI does not recommend the
use of fuel containing MMT. Such fuel may
adversely affect vehicle performance, in-
cluding the emissions control system. Note
that while some fuel pumps label MMT
content, not all do, so you may have to consult your gasoline retailer for more de-
tails.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel
injector cleaner, octane booster, intake valve
deposit removers, etc.) which are sold com-
mercially. Many of these additives intended
for gum, varnish or deposit removal may
contain active solvent or similar ingredients
that can be harmful to the fuel system and
engine.
Octane rating tips
Using unleaded gasoline with an octane
rating lower than recommended above can
cause persistent, heavy spark knock. (Spark
knock is a metallic rapping noise.) If severe,
this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level roads,
it is recommended you have an INFINITI
retailer correct the condition. Failure to
correct the condition is misuse of the
vehicle, for which INFINITI is not respon-
sible.
Incorrect ignition timing will result in knock-
ing, after-run or overheating. This in turn
may cause excessive fuel consumption or
