2023 INFINITI QX55 ignition

IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry of
airborne dust and pollen particles and re-
duces some objectionable outside odors. The
filter is located behind the glove box. For
additional information on change intervals,
see the "Maintenance and schedules" section
of this manual.
If replacement is required, it is recommended
that you visit an INFINITI retailer for this
service.
CLEANING
If your windshield is not clear after using the
windshield-washer or if a wiper blade chat-
ters when running, wax or other material may
be on the blade or windshield.
Clean the outside of the windshield with a
washer solution or a mild detergent. Your
windshield is clean if beads do not form when
rinsing with clear water.
Clean each blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blades with clear water.
If your windshield is still not clear after clean-
ing the blades and using the wiper, replace
the blades.
CAUTION
Worn windshield wiper blades can damage
the windshield and impair driver vision.
REPLACING
Replace the wiper blades if they are worn.
To replace the windshield wiper blades, fol-
low the procedure below:
1. When the ignition switch is ON or within 60 seconds after placing the ignition
switch from the ON to OFF position,
place the windshield wiper and washer
lever into the OFF position.
2. Rapidly lift the windshield wiper and washer lever
OAupwards twice within 0.5
seconds. This action will cause the wipers
to automatically take the service position.

If any electrical equipment does not operate,
check for an open fuse.
Fuses are used in the passenger and engine
compartment. Spare fuses are provided and
can be found in the passenger compartment
fuse box.
When installing a fuse make sure the fuse is
installed in the fuse box securely.ENGINE COMPARTMENT
WARNING
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse
box cover. This could damage the electrical
system or electronic control units or cause
a fire. If any electrical equipment does not come on,
check for an open fuse.
1. Be sure the ignition switch and the head-
light switch are OFF.
2. Open the engine hood.
3. Remove the fuse box cover by pushing the tabs and lifting the cover up.
4. Remove the fuse with the fuse puller. The fuse puller is located in the fuse block in
the passenger compartment.

6. If a new fuse also opens, have the electri- cal system checked and repaired. It is rec-
ommended that you visit an INFINITI re-
tailer for this service.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace with only Genuine NISSAN
parts.

WARNING
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse

NOTE:
The fuse box is located on the driver's side of
the instrument panel. 1. Be sure the ignition switch and the head-
light switch are OFF.
2. Remove the fuse box cover
OAwith a
suitable tool. Use a cloth to avoid damag-
ing the trim.

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 Ve-
hicle (FFV). Do not use E-85 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 appropriate
percentage for that region.
Fuel containing MMT
MMT, or methylcyclopentadienyl manganese
tricarbonyl, is an octane boosting additive.
INFINITI does not recommend the use of fuel
containing MMT. Such fuel may adversely
affect vehicle performance, including 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 details.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (for 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 con-
tain active solvents or similar ingredients that
can be harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rat-
ing lower than recommended can cause per-
sistent, heavy “spark knock.” (“Spark knock”
is a metallic rapping noise.) If severe, this can
lead to engine damage. If you detect a per-
sistent 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 recom-
mended that you have an INFINITI retailer
correct the condition. Failure to correct the
condition is misuse of the vehicle, for which
INFINITI is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which
may cause excessive fuel consumption or en-
gine damage. If any of the above symptoms
are encountered, have your vehicle checked.
It is recommended that you visit an INFINITI
retailer.
However, now and then you may notice light
spark knock for a short time while accelerat-
ing or driving up hills. This is not a cause for
concern, because you get the greatest fuel
benefit when there is light spark knock for a
short time under heavy engine load.

WARNING
A vehicle equipped with All-Wheel Drive
(AWD) should never be tested using a two
wheel dynamometer (such as the dyna-
mometers used by some states for emis-
sions testing), or similar equipment. Make
sure you inform the test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer. Us-
ing the wrong test equipment may result in
transmission damage or unexpected ve-
hicle movement which could result in seri-
ous vehicle damage or personal injury.
Due to legal requirements in some states and
Canadian Provinces, your vehicle may be re-
quired to be in what is called the “ready con-
dition” 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 pat-
terns. Usually, the ready condition can be
obtained by ordinary usage of the vehicle. If a powertrain system component is repaired
or the battery is disconnected, the vehicle
may be reset to a “not ready” condition. Be-
fore taking the I/M test, check the vehicle's
inspection/maintenance test readiness con-
dition. 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 condition is “ready”. It is
recommended that you visit an INFINITI re-
tailer to set the “ready condition” or to pre-
pare 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 per-
formed. The EDR is designed to record data
related to vehicle dynamics and safety sys-
tems 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 depressing the accelerator and/or brake pedal; and,
• How fast the vehicle was traveling.
• Sounds are not recorded.
