tion.NISSAN VEHICLE IMMOBILIZER
SYSTEM
The NISSAN Vehicle Immobilizer system will not
allow the engine to start without the use of the
registered key.
If the engine fails to start using a registered key
(for example, when interference is caused by
another registered key, an automated toll road
device or automatic payment device on the key
ring) , restart the engine using the following pro-
cedure:
1. Leave the ignition switch in the ON position for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
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, NISSAN 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.
● Lock all doors.
● Position seat and adjust head restraints.
● 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 pushed to the ON
position. See “Warning/indicator lights and
audible reminders” in the “Instruments and
controls” section of this manual.
BEFORE STARTING THE ENGINE
Starting and driving5-11

1. Apply the parking brake.
2. Move the shift selector to P (Park) or N(Neutral) . P (Park) is recommended.
The starter is designed not to operate if
the shift selector is in any of the driving
positions.
3. Push the ignition switch to the ON position. Depress the brake pedal and push the igni-
tion switch to start the engine.
To start the engine immediately, push and
release the ignition switch while depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in ex-
tremely cold weather or when restarting,
depress the accelerator pedal a little (ap-
proximately 1/3 to the floor) and while
holding, crank the engine. Release the
accelerator pedal when the engine starts.
● If the engine is very hard to start because
it is flooded, depress the accelerator
pedal all the way to the floor and hold it.
Push the ignition switch to the ON posi-
tion to start cranking the engine. After 5 or
6 seconds, stop cranking by pushing the
ignition switch to LOCK. After cranking
the engine, release the accelerator pedal.
Crank the engine with your foot off the accelerator pedal by depressing the
brake pedal and pushing the push-button

above procedure.
CAUTION
Do not operate the starter for more than
15 seconds at a time. If the engine does
not start, push the ignition switch to the
OFF position and wait 10 seconds before
cranking again, otherwise the starter
could be damaged.
4. Warm-up
Allow the engine to idle for at least 30 sec-
onds after starting. Do not race the engine
while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the en-
gine running for a minimum of2-3minutes
before shutting it off. Starting and stopping
the engine over a short period of time may
make the vehicle more difficult to start.
5. To stop the engine, shift the shift selector to 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 electronic accessories that consume battery power
when the engine is not running (Phone char-
gers, GPS, DVD players, etc.)
2. 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 START (if so equipped)
Vehicles started with the remote start require the
ignition switch to be placed in the ON position
before the shift selector can be moved from the P
(Park) position. To place the ignition switch to the
ON position, follow these steps:
1. Make sure that the Intelligent Key is on you.
2. Apply the brake.
3. Press the ignition switch once to the ON position.

CONTINUOUSLY VARIABLE
TRANSMISSION (CVT)
WARNING
●Do not depress the accelerator pedal
while shifting from P (Park) or N (Neu-
tral) to R (Reverse) , D (Drive) , Ds (Drive
Sport) or manual shift mode (if so
equipped) . Always depress the brake
pedal until shifting is completed. Fail-
ure 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 P (Park) or R (Reverse)
while the vehicle is moving. This could
cause an accident.
CAUTION
●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.
● When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing 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 CVT can operate in two different automatic
drive modes: ● D (Drive) mode - Move the shift selector to D
(Drive) , the transmission is in the normal
forward automatic driving mode. The posi-
tion indicator in the meter shows a “D”. The
D (Drive) mode does not produce a gear
change sensation like a traditional automatic
transmission. ●
Ds (Drive Sport) mode - Move the shift se-
lector from D (Drive) to the to Ds (Drive
Sport) . The position indicator in the meter
shows a “Ds”. In Ds (Drive Sport) mode,
transmission operation changes to Sporty”
driving shift operation, creating a more ag-
gressive acceleration feeling than the D
(Drive) mode and a gear change sensation
when the driver accelerates or when using
the shift paddles (if so equipped) . During Ds
(Drive Sport) mode operation, the driver
must move the shift selector from Ds mode
to D mode and back again to re-select Ds
(Drive Sport) mode.
● To cancel the Ds mode, return the shift se-
lector to the D (Drive) position. The trans-
mission returns to the automatic drive mode.
The CVT can operate in two manual drive modes: ● M (Manual) mode (if so equipped) - With the
shift selector in the Ds (Drive Sport) mode,
using the shift paddles (if so equipped) up
(+) or down (–) produces noticeable up-
shifts and downshifts. The position indicator
in the meter shows a “M”.
● To Ds (Drive Sport) mode return the shift
selector to the D (Drive) mode.
Follow these procedures for maximum vehicle
performance and driving enjoyment.
DRIVING THE VEHICLE
Starting and driving5-13

NOTE:
Engine power may be automatically re-
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 thefoot brake pedal before moving the shift
selector out of the P (Park) position.
2. Keep the foot brake pedal depressed and move the shift selector into a driving gear.
3. Release the foot brake, then gradually start the vehicle in motion.
4. Stop the vehicle completely before shifting the shift selector to the P (Park) position.
The CVT is designed so the foot brake
pedal MUST be depressed before shifting
from P (Park) to any drive position while
the ignition switch is in the ON position.
The shift selector cannot be moved out of P
(Park) and into any of the other gear posi-
tions if the ignition switch is pushed to the
LOCK position. To move the shift selector:
Press the buttonAwhile depressing the
brake pedal
Press the buttonAto shift
Shift without pressing buttonA
Shifting
After starting the engine, fully depress the brake
pedal and move the shift selector from P (Park) to
any of the desired shift positions.
WARNING
Apply the parking brake if the shift selec-
tor is in any position while the engine is
not running. Failure to do so could cause
the vehicle to move unexpectedly or roll
away and result in serious personal injury
or property damage.
P (Park):
CAUTION
To prevent transmission damage, use the
P (Park) or R (Reverse) position only when
the vehicle is completely stopped.
Use the P (Park) shift selector position when the
vehicle is parked or when starting the engine.
Make sure the vehicle is completely stopped.
The brake pedal should be depressed to
move the shift selector 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 selector
into the P (Park) position.
LSD2085
5-14Starting and driving

R (Reverse):
CAUTION
To prevent transmission damage, use the
P (Park) or 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 to move the shift
selector 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 driving.
Ds (Drive Sport):
When the shift selector is shifted from the D
(Drive) to Ds (Drive Sport) position, the transmis-
sion enters the Ds (Drive Sport) mode. Moving
the shift selector to the Ds (Drive Sport) position
allows you to enjoy “sporty” driving shift operation
on a winding road and feel smooth acceleration
or deceleration on a hilly road by moving in a lower gear automatically. When canceling the DS
mode, return the shift selector to the D (Drive)
position. The transmission returns to the normal
driving mode.
Manual shift mode (if so equipped)
When the shift selector is in the Ds (Drive Sport)
position, the transmission is ready for the manual
shift mode. Shift ranges can be selected manu-
ally by pulling the right-side or left-side paddle
shifter.
When shifting up, pull the right side paddle
shifter (+)
C(if so equipped) . The transmission
shifts to the higher range.
When shifting down, pull the left side paddle
shifter ()
B(if so equipped) . The transmission
shifts to the lower range.
LSD2086
Starting and driving5-15

When canceling the manual shift mode, return
the selector lever to the D (Drive) position. The
transmission returns to the normal driving mode.
When you pull the paddle shifter (if so equipped)
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 sec-
onds.
In the manual shift mode, the shift range is dis-
played on the position indicator in the meter.
Shift ranges up or down one by one as follows:
1⇔2⇔ 3⇔ 4⇔ 5⇔ 6⇔ 7
M7 (7th):
Use this position for all normal forward driving at
highway speeds.
M6 (6th) and M5 (5th):
Use this position when driving up long slopes, or
for engine braking when driving down long
slopes.
M4 (4th) , M3 (3rd) and M2 (2nd):
Use for hill climbing or engine braking on downhill
grades. M1 (First):
Use this position when climbing steep hills slowly
or driving slowly through deep snow, sand or
mud, or for maximum engine braking on steep
downhill grades.
● Remember not to drive at high speeds for
extended periods of time in lower than 7
range. This reduces fuel economy.
When shifting up:
Move the shift selector to the + (up) side. (Shifts
to higher range.)
When shifting down:
Move the shift selector to the (down) side.
(Shifts to lower range.)
● Moving the shift selector rapidly to the same
side twice will shift the ranges in succession.
When canceling the manual shift mode:
Return the shift selector 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. ●
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.
5-16Starting and driving

Shift lock release
If the battery charge is low or discharged, the
shift selector may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift selector button pushed.
It will be necessary to jump start or have your
battery charged, see “Jump starting” in the “In
case of emergency” section. Contact your
NISSAN dealer or a professional towing service.
To move the shift selector, complete the following
procedure:1. Push the ignition switch to the LOCK posi- tion. 2. Apply the parking brake.
3. Using a protective cloth on the tip ofa3mm
screwdriver, remove the shift lock release
cover.
● If available, a plastic trim tool can also be
used.
4. Insert the small screwdriver in the shift lock release slot and push down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the trans-
mission as soon as possible.WARNING
If the shift selector 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. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Overdrive (O/D) OFF switch (if so
equipped)
When the O/D OFF switch is pushed with the
shift selector in the D (Drive) position, the
light in the instrument panel illuminates. See
“Overdrive off indicator light” in the “Instruments
and controls” section of this manual.
Use the Overdrive off mode when you need im-
proved engine braking.
To turn off the Overdrive off mode, push the O/D
OFF switch again. The
indicator light will
turn off.
LSD2087LSD2090
Starting and driving5-17

Each time the engine is started, or when the shift
selector is shifted to any position other than D
(Drive) , the Overdrive off mode will be automati-
cally turned off.
Accelerator downshift
— in D position —
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 temperature 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
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safesystem may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction Indicator Light
(MIL)” in the “Instrument and controls” sec-
tion. 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
push the switch back to the ON position.
The vehicle should return to its normal op-
erating condition. If it does not return to its
normal operating condition, have a
NISSAN dealer check the transmission and
repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually reduced.
The reduced speed may be lower than
other traffic, which could increase the
chance of a collision. Be especially care-
ful when driving. If necessary, pull to the
side of the road at a safe place and allow
the transmission to return to normal op-
eration, or have it repaired if necessary.
1. To engage, firmly depress the foot brake.
2. To release:
●Move the shift selector to the P (Park)
position
● Firmly depress the parking brake pedal
and it will release.
● Before driving, be sure the brake warning
light goes out.
