CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)
WARNING
∙ Do not depress the accelerator pedalwhile 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 cau- tion when shifting into a forward or re-
verse 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 vehicle,when stopping the vehicle on an uphill
grade, do not hold the vehicle by depress-
ing 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 enjoy-
ment.
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 dyna-
mometers.
Starting the vehicle
1. After starting the engine, fully depress the foot brake pedal before moving the
shift lever out of the P (Park) position.
This Continuously Variable Transmis- sion 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 lever cannot be moved 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 po-
sition.
3. Release the parking brake and foot brake pedal and then gradually start the
vehicle in motion.
WARNING
∙ Do not depress the accelerator pedalwhile 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 cau- tion when shifting into a forward or re-
verse gear before the engine has warmed
up.
DRIVING THE VEHICLE
Starting and driving5-19

– 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
1to 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)
position 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 idle 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 to hold 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.
Starting and driving5-21

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 right side or left side paddle shifter
AandB. 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 fol-
lows:
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. (Shifts to
higher range.)
When shifting down
Use the (down) side paddle shifter. (Shifts
to lower range.)
∙ The transmission will automatically downshift 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 succes-
sion.
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 transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age 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 transmis-
sion may shift up automatically to a
higher range than selected if the engine
speed is too high. When the vehicle
speed decreases, the transmission auto-
matically 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 extremely low even if manual shift
mode is selected. This is not a malfunc-
tion. 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, 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.
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, refer to “Malfunction In-
dicator Light (MIL)” in the “Instruments and
controls” section of this manual. This will oc-
cur even if all electrical circuits are function-
ing properly. In this case, place the ignition
