2023 INFINITI QX55 automatic transmission

WARNING
When the high fluid temperature protec-
tion mode operation occurs, vehicle speed
may be gradually reduced. The reduced
speed may be lower than other traffic,
which could increase the chance of a colli-
sion. Be especially careful when driving. If
necessary, pull to the side of the road at a
safe place and allow the engine to return to
normal operation; or have it repaired if
necessary.
Engine Malfunction: Power Reduced
Service now
This warning appears when the engine is not
operating under normal conditions. If this
warning comes on, have the system checked.
It is recommended that you visit an INFINITI
retailer for this service.
Engine Malfunction Service now
This warning appears when there is a prob-
lem with the engine. If this warning comes on,
have the system checked. It is recommended
that you visit an INFINITI retailer for this
service.
Engine Stalled: Stop safely
This message appears 30 seconds before the
vehicle is shut down due to an above normal
operating exhaust temperature. The Malfunc-
tion Indicator Light (MIL) and malfunction
warning (red) will illuminate. Have the system
checked. It is recommended that you visit an
INFINITI retailer immediately for this service.
Service CVT (AT) Power reduced
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, climbing
steep grades in high temperatures with heavy
loads), engine power and, under some condi-
tions, vehicle speed will be decreased auto-
matically to reduce the chance of transmis-
sion damage. Vehicle speed can be controlled
with the accelerator pedal, but the engine
and vehicle speed may be reduced.
WARNING
When the high fluid temperature protection
mode operation occurs, vehicle speed may be
gradually reduced. The reduced speed may
be lower than other traffic, which could in-
crease the chance of a collision. Be especially
careful when driving. If necessary, pull to the
side of the road at a safe place and allow the
transmission to return to normal operation;
or have it repaired if necessary.
Blind Spot Warning (BSW)
indicator
This indicator appears when the BSW system
is engaged.
For additional information, see “Blind Spot
Warning (BSW)” (P. 5-45) and “Blind Spot
Intervention® (BSI)” (P. 5-53).
Cruise control indicator
This indicator shows the cruise control sys-
tem status.
When cruise control is activated, a green
circle will appear to indicate it is set. The
vehicle information display will also display
the speed the cruise control was set at. If you
accelerate past the set speed, the speed will
blink until you either cancel cruise control or
go back to the set speed. If cruise control is on
and canceled, the speed will be displayed to
show the speed the vehicle will return to if the
resume button is activated.

The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-held
transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency devicessuch as garage doors, gates, home and
office lighting, entry door locks and security
systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the vehi-
cle's battery is discharged or is discon-
nected, HomeLink® will retain all
programming.
When the HomeLink® Universal Transceiver
is programmed, retain the original transmit-
ter for future programming procedures (Ex-
ample: new vehicle purchases). Upon sale of
the vehicle, the programmed HomeLink®
Universal Transceiver buttons should be
erased for security purposes. For additional
information, see “Programming
HomeLink®” (P. 2-71).WARNING
• Your vehicle's engine should be turned
off while programming the HomeLink®
Universal Transceiver. For additional in-
formation, see “Push-button ignition
switch” (P. 5-14). Do not breathe ex-
haust gases; they contain colorless and
odorless carbon monoxide. Carbon mon-
oxide is dangerous. It can cause uncon-
sciousness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door opener
that lacks safety stop and reverse fea-
tures as required by federal safety stan-
dards. (These standards became effec-
tive for opener models manufactured
after April 1, 1982.) A garage door
opener which cannot detect an object in
the path of a closing garage door and
then automatically stop and reverse
does not meet current federal safety
standards. Using a garage door opener
without these features increases the risk
of serious injury or death.
• During the programming procedure your
garage door or security gate will open
and close (if the transmitter is within
range). Make sure that people or objects
are clear of the garage door, gate, etc.,
that you are programming.PROGRAMMING HOMELINK®
If you have any questions or are having diffi-
culty programming your HomeLink® but-
tons, refer to the HomeLink® web site at:
www.homelink.com or call
1-800-355-3515.
NOTE:
Place the ignition switch in the ON position
(without starting the engine) when pro-
gramming HomeLink®. It is also recom-
mended that a new battery be placed in the
hand-held transmitter of the device being
programmed to HomeLink® for quicker pro-
gramming and accurate transmission of the
radio frequency.

PROGRAMMING HOMELINK®
FOR CANADIAN CUSTOMERS
AND GATE OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit) af-
ter several seconds of transmission – which
may not be long enough for HomeLink® to
pick up the signal during training. Similar to
this Canadian law, some U.S. gate operators
are designed to “timeout” in the same
manner.
If you live in Canada or you are having diffi-
culties training a gate operator orgarage
door opener by using the “Training” proce-
dures, replace “Programming HomeLink®”
step 2 with the following:
NOTE:
When programming a garage door opener,
etc., unplug the device during the “cycling”
process to prevent possible damage to the
garage door opener components.
1. For additional information, see “Program-
ming HomeLink®” step 1, (P. 2-71).
2.
Using both hands, simultaneously press and
hold the desired HomeLink® button and
the hand-held transmitter button. During
training, your hand-held transmitter may
automatically stop transmitting. Continue
to press and hold the desired HomeLink®
button while you press and re-press
(“cycle”) your hand-held transmitter every 2
seconds until the frequency signal has been
learned. The HomeLink® indicator light will
flash slowly and then rapidly after several
seconds upon successful training. DO NOT
release until the HomeLink® indicator light
flashes slowly and then rapidly. When the
indicator light flashes rapidly, both buttons
may be released. The rapid flashing indi-
cates successful training.
Proceed with “Programming HomeLink®”
step 3 to complete.
If the device was unplugged during the pro-
gramming procedure, remember to plug it
back in when programming is completed.
OPERATING THE HOMELINK®
UNIVERSAL TRANSCEIVER
The HomeLink® Universal Transceiver, after
it is programmed, can be used to activate the
programmed device. To operate, simply press
and release the appropriate programmed
HomeLink® Universal Transceiver button.
The amber indicator light will illuminate while
the signal is being transmitted.
For convenience, the hand-held transmitter
of the device may also be used at any time.
PROGRAMMING TROUBLE-
DIAGNOSIS
If the HomeLink® does not quickly learn the
hand-held transmitter information:
• replace the hand-held transmitter batteries with new batteries.
• position the hand-held transmitter with its battery area facing away from the
HomeLink® surface.
• press and hold both the HomeLink® and hand-held transmitter buttons without
interruption.

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)
WARNING
• Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive), or M
(Manual shift mode). Always depress the
brake pedal until shifting is completed.
Failure to do so could cause you to lose
control and have an accident.
• Cold engine idle speed is high, so use
caution when shifting into a forward or
reverse gear before the engine has
warmed up.
• Do not downshift abruptly on slippery
roads. This may cause a loss of control.
• Never shift to either the P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D (Drive)
position while the vehicle is reversing.
This could cause an accident or damage
the transmission.
• Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
CAUTION
• To avoid possible damage to your ve-
hicle, when stopping the vehicle on an
uphill grade, do not hold the vehicle by
depressing the accelerator pedal. The
foot brake should be used for this
purpose.
• Do not hang items on the shift lever. This
may cause an accident due to a sudden
start.
The CVT in your vehicle is electronically con-
trolled to produce maximum power and
smooth operation.
The recommended operating procedures for
this transmission are shown on the following
pages. Follow these procedures for maxi-
mum vehicle performance and driving
enjoyment.
Engine power may be automatically reduced
to protect the CVT if the engine speed in-
creases quickly when driving on slippery
roads or while being tested on some
dynamometers.Starting the vehicle
1. After starting the engine, fully depress the foot brake pedal before shifting the shift
position out of the P (Park) position.
This Continuously Variable Transmission
is designed so that the foot brake pedal
must be depressed before shifting from P
(Park) to any driving position while the
ignition switch is in the ON position.
The shift position cannot be shifted out of
the P (Park) position and into any of the
other positions if the ignition switch is
placed in the OFF position.
2. Keep the foot brake pedal depressed and move the shift lever to a driving position.
3. Release the parking brake and foot brake pedal and then gradually start the vehicle
in motion.
WARNING
• Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse), D (Drive), or M
(Manual shift mode). Always depress the
brake pedal until shifting is completed.
Failure to do so could cause you to lose
control and have an accident.
DRIVING THE VEHICLE
5-18Starting and driving

–Moving the shift lever to the R (Re-
verse) position when driving forward.
– Moving the shift lever to the D (Drive)
position when reversing.
If these operations are attempted, a chime
sounds and the vehicle shifts to the N (Neu-
tral) position.
P (Park)
CAUTION
• To prevent transmission damage, use the
P (Park) position only when the vehicle is
completely stopped.
• Do not slide the shift lever while pressing
the Park button. This may damage the
shift control system.
Use this position when the vehicle is parked
or starting the engine. Always make sure that
the vehicle is completely stopped before
pressing the Park button
O1to engage the P
(Park) position. For maximum safety, the
brake pedal must be depressed before en-
gaging the P (Park) position. Use this position
together with the parking brake. When park-
ing on a hill, first depress the brake pedal,
apply the parking brake and then engage the
P (Park) position. The parking lock should not
be used as a brake when parking. In order to secure the vehicle, always apply the elec-
tronic parking brake in addition to the parking
lock.
In the event of a malfunction of the vehicle’s
electronics, the transmission may lock in the
P (Park) position. Have the vehicle’s electron-
ics checked immediately. It is recommended
that you visit an INFINITI retailer for this
service.
The P (Park) position is automatically en-
gaged if:
• You switch off the ignition switch.
• You unfasten the driver’s seat belt and
open the driver’s door when the vehicle is
stationary or driving at a very low speed
and the transmission is in the D (Drive) po-
sition or R (Reverse) position.
R (Reverse)
CAUTION
To prevent transmission damage, use the R
(Reverse) position only when the vehicle is
completely stopped. Use the R (Reverse) position to back up. Make
sure the vehicle is completely stopped before
selecting the R (Reverse) position.
The brake
pedal must be depressed and the shift lever
button pressed to move the shift lever from
the home position to R (Reverse).
If the vehicle is placed in the R (Reverse)
position while forwarding, the chime will
sound and the vehicle will switch into the N
(Neutral) position.
N (Neutral)
Neither forward nor reverse gear is engaged.
The engine can be started in this position. You
may shift to N (Neutral) and restart a stalled
engine while the vehicle is moving. You can
select this position by holding the shift lever
at this position for 0.5 seconds.
D (Drive)
Use this position for all normal forward driv-
ing. The CVT changes gears automatically. All
forward gears are available. If the vehicle is
placed in the D (Drive) position while revers-
ing, the chime will sound and the vehicle will
switch into the N (Neutral) position.
