2023 INFINITI QX50 automatic transmission

To activate the Neutral hold mode, perform
the following operations:
1. Push the ignition switch to start theengine.
2. Release the electronic parking brake.
3. Depress and hold the brake pedal.
4. Press the P (Park) button.
5. Slide the shift lever to the N (Neutral) position, and hold it for 0.5 second until
“N” appears in the vehicle information
display.
6. Slide the shift lever to the N (Neutral) position again, and hold it for 0.5 seconds,
until a message “Neutral Hold Mode has
been activated” appears in the vehicle in-
formation display. For additional informa-
tion, see “Neutral Hold Mode activated
indicator” (P. 2-26).
7. The ignition switch has to be kept in the ON position. Otherwise Neutral hold
mode is canceled and the P (Park) position
is engaged automatically.
To exit the Neutral hold mode, place the shift
lever in any position other than the N (Neu-
tral) position.NOTE:
• It is necessary to perform the steps 4
through 6 within approximately 5 seconds
to prevent incorrect operation.
• When the shifter is changed to the N (Neu-
tral) position, approximately 5 seconds
later, a message will appear in the vehicle
information display. For additional infor-
mation, see “Neutral Hold Mode guidance
indicator” (P. 2-27).
• If the Neutral hold mode is unavailable, a
message will appear in the vehicle infor-
mation display. For additional informa-
tion, see “Neutral Hold Mode was not ac-
tivated indicator” (P. 2-27). To activate
the Neutral hold mode, wait for a while
without shifting operation and then per-
form the operations again.
Manual shift mode
When the shift lever is shifted to the D (Drive)
position again with the vehicle in the D (Drive)
position while driving, the transmission en-
ters the manual shift mode. Shift ranges can
be selected manually by pulling the paddle
shifters on the steering wheel.
When shifting up, pull the right-side paddle
shifter (+)
OA. The transmission shifts to the
higher range.
When shifting down, pull the left-side paddle
shifter (−)
OB. The transmission shifts to the
lower range.

5-22Starting and driving

When canceling the manual shift mode, move
the shift lever to the D (Drive) position again.
The transmission returns to the normal driv-
ing mode.
When you pull the paddle shifter while in the
D (Drive) position, the transmission will shift
to the upper or lower range temporarily. The
transmission will automatically return to the
D (Drive) position after a short period of time.
If you want to return to the D (Drive) position
manually, pull and hold the paddle shifter for
about 1.5 seconds.
In the manual shift mode, the shift range is
displayed in the vehicle information display.
Shift ranges up or down one by one as
follows:
1M⇔2M⇔3M ⇔4M ⇔5M ⇔6M ⇔7M ⇔
8M
8 (8th)
Use this position for all normal forward driv-
ing at highway speeds.
7 (7th), 6 (6th) and 5 (5th)
Use this position when driving up long slopes,
or for engine braking when driving down long
slopes.
4 (4th), 3 (3rd) and 2 (2nd)
Use these positions for hill climbing or engine
braking on downhill grades.
1 (1st)
Use this position when climbing steep hills
slowly or driving slowly through deep snow,
or for maximum engine braking on steep
downhill grades.
• Remember not to drive at high speeds for extended periods of time in lower than the
8th range. This reduces fuel economy.
• Pulling the same paddle shifter twice will shift the ranges in succession. However, if
this motion is rapidly done, the second
shifting may not be completed properly.
• In the manual shift mode, the transmission
may not shift to the selected gear. This
helps maintain driving performance and
reduces the chance of vehicle damage or
loss of control.
• In the manual shift mode, the transmission
may shift up automatically to a higher
range than selected if the engine speed is
too high. When the vehicle speed de-
creases, the transmission automatically
shifts down and shifts to 1st gear before
the vehicle comes to a stop.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the ac-
celerator pedal to the floor. This shifts the
transmission down into a lower gear, de-
pending on the vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid tempera-
ture protection mode. If the fluid temperature
becomes too high (for example, when climb-
ing steep grades in high temperatures with
heavy loads, such as when towing a trailer),
engine power and, under some conditions,
vehicle speed will be decreased automatically
to reduce the chance of transmission dam-
age. Vehicle speed can be controlled with the
accelerator pedal, but the engine and vehicle
speed may be limited.
Fail-safe
When the fail-safe operation occurs, the
Continuously Variable Transmission will not
be shifted into the selected driving position.
Starting and driving5-23

If the vehicle is driven under extreme condi-
tions, such as excessive wheel spinning and
subsequent hard braking, the fail-safe sys-
tem may be activated. The Malfunction Indi-
cator Light (MIL) may come on to indicate
the fail-safe mode is activated. For addi-
tional information, see “Malfunction Indica-
tor Light (MIL)” (P. 2-15). This will occur
even if all electrical circuits are functioning
properly. In this case, place the ignition
switch in the OFF position and wait for
10 seconds. Then place the ignition switch
back in the ON position. The vehicle should
return to its normal operating condition. If it
does not return to its normal operating con-
dition, have the transmission checked and re-
paired, if necessary. It is recommended that
you visit an INFINITI retailer for this service.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs, ve-
hicle speed may be gradually reduced. The
reduced speed may be lower than other
traffic, which could increase the chance of
a collision. Be especially careful when driv-
ing. 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.
WARNING
• Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
• Do not release the parking brake from
outside the vehicle.
• Do not use the shift lever in place of the
parking brake. When parking, be sure the
parking brake is fully engaged. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm day
can quickly become high enough to cause
a significant risk of injury or death to
people and pets.
The electronic parking brake can be applied
or released automatically or by operating the
parking brake switch.
AUTOMATIC OPERATION
The electronic parking brake is automatically
released as soon as the vehicle starts and the
accelerator pedal is depressed.
The driver’s seat belt needs to be fastened.
WARNING
• The electronic parking brake will not be
automatically applied when the engine is
stopped without using the ignition
switch (for example, by engine stalling).
Without the vehicle stationary, the elec-
tronic parking brake will not be auto-
matically applied even if the engine is
turned off with the ignition switch.

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:
• The transmission is shifted to a forward orreverse gear.
• The vehicle is stopped completely on a hill by applying the brake. The maximum hold-
ing time is 2 seconds. After 2 seconds the
vehicle will begin to roll back and the hill
start assist system will stop operating
completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral), the Park button is pressed to place the
vehicle in the P (Park) position or on a flat and
level road.
The Hill Start Assist function status can be
checked in the “Chassis Control” mode in the
vehicle information display. For additional in-
formation, see “Vehicle information display”
(P. 2-19). The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
