check engine INFINITI Q70 HYBRID 2018 Owner's Guide

The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The main-
tenance schedule indicates at which mile-
age/time intervals each item requires
service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer
to “General maintenance” (P.9-2).
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You
are not required to perform maintenance on
these items in order to maintain the warran-
ties which come with your vehicle. Other
maintenance items and intervals are re-
quired.
When applicable, additional information can
be found in the “8. Do-it yourself” section of
this manual.
NOTE:
INFINITI does not advocate the use of non-
OEM approved aftermarket flushing sys-
tems and strongly advises against perform-
ing these services on an INFINITI product.
Many of the aftermarket flushing systems
use non-OEM approved chemicals or sol-
vents, the use of which has not been
validated by INFINITI.
For recommended fuel, lubricants, fluids,grease, and refrigerant, refer to “Capacities
and recommended fluids/lubricants” (P.10-
2) of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE
Engine air filter:
Replace at specified intervals. When driving
for prolonged periods in dusty conditions,
check/replace the filter more frequently.
Engine coolant*:
Replace coolant at the specified interval.
When adding or replacing coolant, be sure to
use only Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) or equivalent with the
proper mixture. (Refer to “Engine cooling
system” (P.8-5) to determine the proper
mixture for your area.)
NOTE:
Mixing any other type of coolant or the use
of non-distilled water may reduce the
recommended service interval of the cool-
ant.
Hybrid Electronic Vehicle (HEV) inverter
coolant:
Replace inverter coolant at the specified
interval. When adding or replacing coolant,
be sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or equivalent
with the proper mixture. (Refer to “Inverter
cooling system” (P.8-7) to determine the
proper mixture for your area.)
NOTE:
Mixing any other type of coolant or the use
of non-distilled water may reduce the
recommended service interval of the cool-
ant.
Engine oil and oil filter:
Replace engine oil and oil filter at the
specified intervals. For recommended oil
grade and viscosity refer to “Capacities and
recommended fluids/lubricants” (P.10-2).
Engine valve clearance*:
Inspect only if valve noise increases. Adjust
valve clearance if necessary.
Evaporative emissions control vapor lines*:
Check vapor lines and connections for leaks
or looseness. Tighten connections or replace
parts as necessary.
Fuel lines*:
Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tight-
en connections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new
plugs of the type as originally equipped.

damage to the engine. If any of the above
symptoms are encountered, have your ve-
hicle checked. It is recommended you visit an
INFINITI retailer for servicing.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is no
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.

ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose the correct grade,
quality, and viscosity engine oil to ensure
satisfactory engine life and performance,
see “Capacities and recommended fluids/
lubricants” (P.10-2). INFINITI recommends
the use of an energy conserving oil in order
to improve fuel economy.
Select only engine oils that meet the Amer-
ican Petroleum Institute (API) certificationor International Lubricant Standardization
and Approval Committee (ILSAC) certifica-
tion and SAE viscosity standard. These oils
have the API certification mark on the front
of the container. Oils which do not have the
specified quality label should not be used as
they could cause engine damage.Oil additives
INFINITI does not recommend the use of oil
additives. The use of an oil additive is not
necessary when the proper oil type is used
and maintenance intervals are followed.
Oil which may contain foreign matter or has
been previously used should not be used.
Technical and consumer information10-5

Do not attempt to test the vehicle on a
dynamometer (such as the dynamometers
used by some states for emissions testing),
or similar equipment. Doing so may cause
damage to the drivetrain or the high voltage
battery. Make sure you inform test facility
personnel that your vehicle is hybrid. Using
the wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or pearsonal injury.
Due to legal requirements in some states/
areas, your vehicle may be required to be in
what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the
emission control system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition” can
be obtained by ordinary usage of the vehicle.
If a powertrain system component is re-
paired or the 12-volt battery is discon-
nected, the vehicle may be reset to a “not
ready condition”. Before taking the I/M test,
check the vehicle’s inspection/maintenance
test readiness condition. Place the ignition
switch in the ON position without starting
the engine. If the Malfunction Indicator
Light (MIL) comes on steady for 20 seconds
and then blinks for 10 seconds, the I/M test
condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condi-tion is “ready”.
It is recommended you visit an INFINITI
retailer to set the “ready condition” or to
prepare the vehicle for testing.
This vehicle is equipped with an Event Data
Recorder (EDR). The main purpose of an
EDR is to record, in certain crash or near
crash-like situations, such as an air bag
deployment or hitting a road obstacle, data
that will assist in understanding how a
vehicle’s systems performed. The EDR is
designed to record data related to vehicle
dynamics and safety systems for a short
period of time, typically 30 seconds or less.
The EDR in this vehicle is designed to record
such data as:
.
How various systems in your vehicle were
operating;
. Whether or not the driver and passenger
safety belts were buckled/fastened;
. How far (if at all) the driver was depres-
sing the accelerator and/or brake pedal;
and,
. How fast the vehicle was traveling.
. Sounds are not recorded.
These data can help provide a better under-
standing of the circumstances in which
crashes and injuries occur.
NOTE: EDR data are recorded by your
vehicle only if a nontrivial crash situation
occurs; no data are recorded by the EDR
under normal driving conditions and no
personal data (e.g. name, gender, age and
crash location) are recorded. However, other
parties, such as law enforcement, could
combine the EDR data with the type of
