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. Re-
start the engine using the following procedures:1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK position and wait approximately 5 seconds.
3. Repeat Step 1 and 2 again.
4. Restart the engine while holding the device (which may have caused the interference)
separate from the registered key.
If the no start condition re-occurs, INFINITI rec-
ommends placing the registered key on a sepa-
rate 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 when-
ever 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 posi-
tion. For additional information, refer to
“Warning lights, indicator lights and audible
reminders” in the “Instruments and controls”
section of this manual. 1. Apply the parking brake.

DRIVING THE VEHICLE
Starting and driving5-17

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.
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 maximum vehicle
performance and driving enjoyment.

duced to protect the CVT if the engine
speed increases 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 moving the shift
lever out of the P (Park) position.
This CVT 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 position while the ready light illu-
minates.
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

tral) to R (Reverse) or D (Drive) position.
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 re-
versing. This could cause an accident or
damage 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.

only when the vehicle is completely
stopped.
P (Park)
CAUTION
To prevent transmission damage, use the
P (Park) position only when the vehicle is
completely stopped
Use the P (Park) shift lever position when the
vehicle is parked or when starting the engine.
Make sure the vehicle is completely stopped.
The brake pedal must be depressed and
the shift lever button pushed in to move the
shift lever from N (Neutral) or any drive
position to P (Park) . Apply the parking brake.
When parking on a hill, apply the parking brake
first, then move the shift lever into the P (Park)
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 pushed in to move the shift lever
from P (Park) , N (Neutral) or any drive po-
sition 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 driving.
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
LSD2358
Starting and driving5-19

manual shift mode, return the shift lever to the D
(Drive) position. The transmission returns to au-
tomatic 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 manu-
ally. 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 follows:
1⇔2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7
7 (7th)
Use this position for all normal forward driving 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 maximum 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 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
Return the shift lever to the D (Drive) position to
return the transmission to the normal driving
mode. ●
In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving perfor-
mance and reduces the chance of ve-
hicle damage or loss of control.
● When this situation occurs, the CVT
position 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 en-
gine speed is too high. When the ve-
hicle speed decreases, the transmis-
sion 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.

For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid temperature
protection mode. If the fluid temperature be-
comes too high (for example, when climbing
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 damage. 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 CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The Malfunction
Indicator Light (MIL) may come on to indi-
cate the fail-safe mode is activated. For
additional information, refer to “Malfunc-
tion Indicator Light (MIL)” in the “Instru-
