2018 INFINITI Q70 HYBRID air filter

2-46Instruments and controls
cator lighton the control knob goes
off at the OFF position.
The climate controlled seat has air filters.
If the climate controlled seat is not
functioning properly, it may indicate the
air filters may be clogged. To check the
air filters for the climate controlled seat,
it is recommended you visit an INFINITI
retailer.
WARNING
Do not use or allow occupants to use the
climate controlled seats if you or the
occupants can not monitor seat tem-
peratures or have an inability to feel pain
in those body parts in contact with the
seat. Use of the climate controlled seats
by such people could result in serious
injury.
CAUTION
. The 12-volt battery could run down if
the climate controlled seat is oper-
ated while the hybrid system is not
running.
. Do not use the climate controlled seat
for extended periods or when no one is using the seat.
. Do not put anything on the seat
which insulates heat, such as a blan-
ket, cushion, seat cover, etc. Other-
wise, the seat may become
overheated.
. Do not place anything hard or heavy
on the seat or pierce it with a pin or
similar object. This may result in
damage to the climate controlled
seat.
. Any liquid spilled on the seat should
be removed immediately with a dry
cloth.
. The climate controlled seat has an air
filter. Do not operate climate con-
trolled seat without an air filter. This
may result in damage to the system.
. When cleaning the seat, never use
gasoline, thinner, or any similar ma-
terials.
. If any malfunctions are found or the
climate controlled seat does not op-
erate, turn the switch off and have
the system checked. It is recom-
mended you visit an INFINITI retailer
for this service.

The warning systems switch is used to turn
on and off the warning systems (Lane
Departure Warning (LDW) and Blind Spot
Warning (BSW) systems) that are activated
using the settings menu on the center
display.
When the warning systems switch is turned
off, the indicator
on the switch is off. The
indicator will also be off if all of the warning
systems are deactivated using the settings
menu.
The LDW system will sound a warning chime
and blink the LDW indicator light (orange) to
alert the driver if the vehicle is traveling close
to either the left or the right of a traveling
lane with detectable lane markers. (See
WARNING SYSTEMS SWITCH (if
so equipped)

ture. Do not put anything on or around the
sensors.
LINKING INTELLIGENT KEY
The Climate control system settings can be
memorized for each Intelligent Key. For
more details, see “Setting memory function”
(P.3-29).
SERVICING CLIMATE CONTROL
The climate control system in your vehicle is
charged with a refrigerant designed with the
environment in mind. This refrigerant will
not harm the earth’s ozone layer. However,
special charging equipment and lubricant are
required when servicing your INFINITI air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to your
climate control system. (See “Capacities and
recommended fluids/lubricants” (P.10-2)
for climate control system refrigerant and
lubricant recommendations.)
Your INFINITI retailer will be able to service
your environmentally friendly climate control
system.
WARNING
The system contains refrigerant under
high pressure. To avoid personal injury,
any air conditioner service should be
done only by an experienced technician
with the proper equipment.
In-cabin microfilter
The climate control system is equipped with
a natural grape seed polyphenol filter which
collects and neutralizes dirt, pollen, dust,
allergens (such as cedar pollen, tick shells)
etc. To make sure that the air conditioner
heats, defogs and ventilates efficiently, re-
place the filter in accordance with the
specified maintenance intervals listed in the
“9. Maintenance and schedules” section. It is
recommended to see an INFINITI retailer to
replace the filter.
The filter should be replaced if the air flow
decreases significantly or if windows fog up
easily when operating the heater or air
conditioner.

Remove the retainers
as illustrated and
pull out the filter element.
The filter element should not be cleaned and
reused. Replace it according to the main-
tenance intervals. See “9. Maintenance and
schedules” section of this manual for main-
tenance intervals. When replacing the filter, wipe the inside of the air cleaner housing and
the cover with a damp cloth.
WARNING
.
Operating the engine with the air
cleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it isn’t
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed, and be care-
ful when working on the engine with
the air cleaner removed.
. Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
AIR CLEANER

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.

with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled
water. Mixing any other type of coolant or
the use of non-distilled water may reduce
the life expectancy of the factory fill cool-
ant.
(5) First replacement interval is 125,000
miles (200,000 km) or 180 months. After
