INTELLIGENT ALL-WHEEL
DRIVE (AWD) DRIVING SAFETY
PRECAUTIONS (if so equipped)
WARNING
∙ Replacing tires with those not originallyspecified by INFINITI could affect the
proper operation of the TPMS.
∙ Always use tires of the same type, size, brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the front
wheels when driving on slippery roads
and drive carefully.
∙ This vehicle is not designed for off-road (rough road) use. Do not drive on sandy or
muddy roads that tires may get stuck in.
∙ For AWD equipped vehicles, do not at- tempt to raise two wheels off the ground
and shift the transmission to any D
(Drive) or R (Reverse) position with the
engine running. Doing so may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury. ∙ Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer (such
as the dynamometers used by some
states for emissions testing), or similar
equipment even if the other two wheels
are raised off the ground. Make sure you
inform test facility personnel that your
vehicle is equipped with AWD before it is
placed on a dynamometer. Using the
wrong test equipment may result in
drivetrain damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
∙ When a wheel is off the ground due to an unlevel surface, do not spin the wheel
excessively.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed three consecutive
times in quick succession or the ignition
switch is pushed and held for more than
2 seconds.) If the engine stops while the
vehicle is being driven, this could lead to a
crash and serious injury.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated payment device on
the key ring. Restart the engine using the
following procedures:1. Leave the ignition switch in the ON po- sition for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position and wait approximately
5 seconds.
3. Repeat Step 1 and 2 again.
4. Restart the engine while holding the de- vice (which may have caused the inter-
ference) separate from the registered
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passengers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Move the shift lever to P (Park) or N
(Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.

position and wait 10 seconds before crank-
ing again, otherwise the starter could be
damaged.4. Warm-up:
Allow the engine to idle for at least
30 seconds after starting. Do not race
the engine while warming it up. Drive at a
moderate speed for a short distance
first, especially in cold weather. In cold
weather, keep the engine running for a
minimum of2-3minutes before shut-
ting it off. Starting and stopping the en-
gine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, place the shift lever in the P (Park) position and push the
ignition switch to the OFF position. NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
1. Installation or extended use of elec-
tronic accessories that consume battery
power when the engine is not running
(phone chargers, GPS, DVD players,
etc.).
2. The vehicle is not driven regularly
and/or only driven short distances. In
these cases, the battery may need to be
charged to maintain battery health.
REMOTE ENGINE START (if so
equipped)
Vehicles started with the Remote Engine
Start require the ignition switch to be placed
in the ON position before the shift lever can

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 depressing
the accelerator pedal. The foot brake
should be used for this purpose.
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 LOCK, OFF or ACC posi-
tion while the ready light illuminates.
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.

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
P (Park), N (Neutral) or any drive position to
R (Reverse).
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.
D (Drive)
Use this position for all normal forward driv-
ing.
Manual shift mode
When the shift lever is in the manual shift
gate, the transmission is ready for the manual
shift mode. Shift ranges can be selected
manually by moving the shift lever up or
down. To cancel manual shift mode, return the shift lever to the D (Drive) position. The
transmission returns to automatic driving
mode.
When the shift lever is shifted from D (Drive)
to the manual shift gate with the vehicle
stopped or while driving, the transmission
enters the manual shift mode. Shift ranges
can be selected manually. In the manual shift
mode, the shift range is displayed on the
position indicator in the meter. When shifting
the shift lever to the manual shift gate, the
position indicator displays 1 (1st) up to 7 (7th)
depending on vehicle speed.
Shift ranges up or down one by one as fol-
lows:
1⇔
2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7
7 (7th)
Use this position for all normal forward driv-
ing at highway speeds.
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.
∙ Remember not to drive at high speeds for extended periods of time in lower than
7th gear. This reduces fuel economy.
When shifting up
Move the shift lever to the + (up) side. (Shifts
to higher range.)
When shifting down
Move the shift lever to the (down) side.
(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
Return the shift lever to the D (Drive) position
to return the transmission to the normal driv-
ing mode.
Starting and driving5-21

∙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 light 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.
Shift lock release
If the battery charge is low or discharged, the
shift lever may not be moved from the P
(Park) position even with the brake pedal de-
pressed and the shift lever button pressed. To
move the shift lever, perform the following
procedure:
1. Push the ignition switch to the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock release cover us- ing a suitable tool. 4. Push down the shift lock release using a
suitable tool.
5. Press the shift lever button and move the shift lever to the N (Neutral) position
while holding down the shift lock release.
The vehicle may be moved to the desired
location. Replace the removed shift lock
release cover after the operation.
If the shift lever cannot be moved out of the P
(Park) position, have the Continuously Vari-
able Transmission system checked as soon as
possible. It is recommended that you visit an
INFINITI retailer for this service.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is running
and the brake pedal is depressed, the stop
lights may not work. Malfunctioning stop
lights could cause an accident injuring your-
self and others.
