Neutral hold mode function (if so
equipped)
This function enables you to get out of the
vehicle when it is in the N (Neutral) position,
while the engine is running. While this func-
tion is activated, the vehicle can be moved by
pushing with hand (when car washing). When
using this function, release the electronic
parking brake.
WARNING
• Use this function on a level surface only.
Failure to do so may cause the vehicle to
move accidentally and could result in a
collision or serious personal injury.
• Do not use this function for a purpose
other than car washing.
• Do not turn the engine off after neutral
hold mode function is activated, other-
wise the N (Neutral) position will not be
kept and the vehicle will automatically
be placed in the P (Park) position.
• If this function is not activated regard-
less of proper operation, transmission
may malfunction. It is recommended that
you visit an INFINITI retailer for this
service. To activate the Neutral hold mode, perform
the following operations:
1. Push the ignition switch to start the
engine.
2. Release the electronic parking brake.
3. Depress and hold the brake pedal.

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”
(P. 2-27).
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”
(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” (P. 2-27). To activate the Neutral
hold mode, wait for a while without shift-
ing operation and then perform the opera-
tions again.

Manual shift mode
The transmission enters the manual shift
mode by moving the shift lever again to the D
(Drive) position when the vehicle is in the D
range.
You can select the manual shift range by
pulling the left side or right side paddle shifter
OAandOB. To cancel the manual shift mode,
move the shift lever to the D (Drive) position
again. The transmission returns to the auto-
matic drive mode.
When the shift lever is shifted from D (Drive)
to the manual shift mode with the vehicle stopped or while driving, the transmission
enters the manual shift mode. Shift ranges
can be selected manually. Shift ranges can
also be selected using the paddle shifters on
the steering wheel. When you pull the paddle
shifter while in the D (Drive) position, the
transmission will shift to the upper or lower
range temporarily. If the paddle shifters are
not used for about 5–10 seconds, the trans-
mission will automatically return to the D
(Drive) position. If you want to return to the D
(Drive) position manually, pull and hold either
paddle shifter for about 1.5 seconds.In the manual shift mode, the shift range is
displayed on the position indicator in the me-
ter. When moving the shift lever to the
manual shift mode, the position indicator dis-
plays 1 (1st) up to 8 (8th) depending on ve-
hicle speed.
Shift ranges up or down one by one as
follows:
1⇔
2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7⇔ 8
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 when driving slowly, or for maxi-
mum engine braking on steep downhill
grades.

5-22Starting and driving

• Remember not to drive at high speeds forextended periods of time in lower than 8th
gear. This reduces fuel economy.
When shifting up
Use the + (up) side paddle shifter
OB. (Shifts to
higher range.)
When shifting down
Use the − (down) side paddle shifter
OA.
(Shifts to lower range.)
• The transmission will automatically down- shift the gears. (For example, if you select
the 3rd range, the transmission will shift
down between the 3rd and 1st gears.)
• Moving the shift lever rapidly to the same side twice will shift the ranges in
succession.
When canceling the manual shift mode
Move the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode.
• 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. •
When this situation occurs, the Continu-
ously Variable Transmission (CVT) posi-
tion indicator will blink and the chime will
sound.
• 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.
• CVT operation is limited to automatic drive mode when CVT fluid temperature is ex-
tremely low even if manual shift mode is
selected. This is not a malfunction. When
CVT fluid warms up, manual mode can be
selected.
• When the CVT fluid temperature is high, the shift range may upshift in lower rpm
than usual. This is not a malfunction.
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), engine power and, under some
conditions, vehicle speed will be decreased
automatically to reduce the chance of trans-
mission damage. Vehicle speed can be con-
trolled 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.
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 condition,
have the transmission checked and repaired,
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 will apply auto-
matically if the ignition switch is placed in the
OFF position when the brake force is main-
tained by the automatic brake hold function.
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.
