maintenance reset INFINITI QX55 2023 Owners Manual

•When using a wheel without the TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure
warning light will flash for approxi-
mately 1 minute. The light will remain on
after 1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit an INFINITI retailer for these
services.
• Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
• The TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
• If the vehicle is being driven at speeds of
less than 16 mph (25 km/h), the TPMS
may not operate correctly.
• Be sure to install the specified size of
tires to the four wheels correctly.
Malfunction Indicator Light
(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may indi-
cate a potential emission control
malfunction.
The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3
gallons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light should
turn off if no other potential emission control
system malfunction exists.
If this indicator light comes on steady for 20
seconds and then blinks for 10 seconds when
the engine is not running, it indicates that the
vehicle is not ready for an emission control
system inspection/maintenance test. For ad-
ditional information, see “Readiness for
Inspection/Maintenance (I/M) test”
(P. 10-24).
Operation
The MIL will come on in one of two ways:
• MIL on steady — An emission control sys- tem malfunction has been detected. Check
the fuel-filler cap. If the fuel-filler cap is
loose or missing, tighten or install the cap
and continue to drive the vehicle. The
light should turn off after a few driving
trips. If thelight does not turn off
after a few driving trips, have the vehicle
checked. It is recommended that you visit
an INFINITI retailer for this service. You do
not need to have your vehicle towed to the
retailer.
• MIL blinking — An engine misfire has been detected which may damage the emission
control system. To reduce or avoid emis-
sion control system damage:– Do not drive at speeds above 45 mph (72 km/h).
– Avoid hard acceleration or deceleration.
– Avoid steep uphill grades.
– If possible, reduce the amount of cargo being hauled or towed.
The MIL may stop blinking and come on
steady. Have the vehicle checked. It is recom-
mended that you visit an INFINITI retailer for
this service. You do not need to have your
vehicle towed to the retailer.

OIL CONTROL SYSTEM
Your vehicle is equipped with oil control sys-
tem. It calculates engine oil and filter change
intervals based on driving conditions. Driving
in the following severe conditions will shorten
the engine oil and filter change interval.
How driving conditions affect OCS display
timing
ConditionsDriving Scene Display timing
Light • Freeway driving
• City driving (flat/moderate hills)
• No heavy loads
• No extended engine idling Normal
Extreme • Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures remaining below
freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi or door-to-door delivery use.
• Using a car-top carrier.
• Driving with frequent use of braking or in mountainous areas.
• Sustained high speed driving. Early
CAUTION
• If the oil replacement indicator is dis-
played, change the engine oil within two
weeks or less than 500 miles (800 km).
• Operating your vehicle with deterio-
rated oil can damage the engine. •
If your oil replacement indicator resets
prematurely or becomes inoperative,
please change the oil within six months
or 3,750 miles (6,000 km) from your last
oil change.
9-8Maintenance and schedules

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.
