Make sure the area around the vehicle is
clear.
● Check fluid levels such as engine oil, cool-
ant, brake fluid and window 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.
● Lock all doors.
● Position seat and adjust head restraints.
● Adjust inside and outside mirrors.
● Fasten seat belts and ask all passengers to
do likewise.

1. Apply the parking brake.
2. Move the selector lever to the P (Park) orN (Neutral) position. (P is recommended.)
The starter is designed not to operate unless
the selector lever is in either of the above
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 depressing
the brake pedal with the ignition switch in
any position.
● If the engine is very hard to start in
extremely cold weather or when restart-
ing, depress the accelerator pedal a little
(approximately 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 OFF. 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 igni-
tion switch to start the engine. If the
engine starts, but fails to run, repeat the
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 OFF 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
seconds after starting. Do not race the en-
gine while warming it up. Drive at moderate
speed for a short distance first, especially in
cold weather. In cold weather, keep the
engine running for a minimum of2-3
minutes before shutting it off. Starting and
stopping the engine over a short period of
time may make the vehicle more difficult to
start.
When racing the engine up to 4,000 rpm
(VK56VD engine) or 4,500 rpm (VQ37VHR
engine) or more under no load condition, the
engine will enter the fuel cut mode.
5. To stop the engine, shift the selector lever
to the P (Park) position and push the
ignition switch to the OFF position.
In preparation for the next engine start, the
engine may have a slightly delayed shutoff
after pushing the ignition switch to the OFF
position, depending on the driving condi-
tions (VK56VD engine models).

AUTOMATIC TRANSMISSION
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. Follow these procedures for maximum
vehicle performance and driving enjoyment.
Starting the vehicle
After starting the engine, fully depress the foot
brake pedal and push the selector lever button
before shifting the selector lever to the R (Re-
verse), N (Neutral), D (Drive) or Manual shift
mode position. Be sure the vehicle is fully
stopped before attempting to shift the selector
lever.
This automatic transmission model is designed
so that the foot brake pedal must be depressed
before shifting from P (Park) to any drive posi-
tion while the ignition switch position is ON.
The selector lever cannot be moved out of the P
(Park) position and into any of the other gear
positions if the ignition switch is pushed to the
LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed andpush the selector lever button to shift into
a driving gear.
2. Release the parking brake and foot brake, then gradually start the vehicle in motion.
WARNING
●Do not depress the accelerator pedal while
shifting from P (Park) or N (Neutral) to R (Re-
verse), D (Drive) or manual shift mode. Al-
ways 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 reverse
gear before the engine has warmed up.
● Never shift to P (Park) or R (Reverse) while
vehicle is moving forward. Never shift to P
(Park) or D (Drive) while vehicle is moving
rearward. Failure to do so could cause you to
lose control and have an accident.
CAUTION
● 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.
● Do not downshift abruptly on slippery roads.
This may cause a loss of control.

Failure to do so could cause the vehicle to move
unexpectedly or roll away and result in serious
personal injury or property damage.
CAUTION
Make sure the vehicle is completely stopped
and the transmission is in the P (Park) position.
P (Park) position :
Use this selector 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 selector lever
button pushed in to move the selector lever from
the N (Neutral) position or any drive position to
the P (Park) position. Apply the parking brake.
When parking on a hill, apply the parking brake
first, then move the selector lever to the P (Park)
position.
CAUTION
Use this position only when the vehicle is com-
pletely stopped.

Manual shift mode
When the selector lever is in the manual shift
gate, the transmission is ready for the manual
shift mode. Shift ranges can be selected manu-
ally by moving the selector lever up or down, or
pulling the right-side or left-side paddle shifter
(if so equipped).
When shifting up, move the selector lever to the
+ (up) side or pull the right-side paddle shifter
(+)
A(if so equipped). The transmission shifts
to the higher range.
When shifting down, move the selector lever to
the (down) side or pull the left-side paddle shifter ()
B(if so equipped). The transmis-
sion shifts to the lower range.
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 while in the D
(Drive) position, the transmission will shift to
the upper or lower range temporarily. The trans-
mission 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
displayed on the position indicator in the meter.
Shift ranges up or down one by one as follows:
M1 →
←M2→
←M3→
←M4→
←M5→
←M6→
←M7
M7 (7th) :
Use these positions for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th) :
Use this position when driving up long slopes,
or for engine braking when driving down long
slopes.
M4 (4th),M3 (3rd) andM2 (2nd) :
Use these positions for hill climbing or engine
braking on downhill grades.
M1 (1st) :
Use this position when climbing steep hills
slowly or driving slowly through deep snow, 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.
● Moving the selector lever rapidly to the same
side twice will shift the ranges in succes-
sion.
● 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 con-
trol.
When this situation occurs, the Automatic
Transmission (AT) position indicator light (on
the dot matrix liquid crystal display) will
blink and the chime will sound.

drive mode select switch to the
position.
“STANDARD” appears in the vehicle information
display for 2 seconds.
SPORT MODE
Adjusts the engine and transmission points to
enhance performance. If the vehicle is equipped
with 4-Wheel Active Steer (4WAS) system, the
SPORT mode adjusts this system’s settings to
provide faster steering ratios. If the vehicle is
equipped with the active trace control system,
the amount of brake control provided by active
trace control is reduced. (See “4 WHEEL ACTIVE
STEER (4WAS) SYSTEM” later in this section or
“VEHICLE DYNAMIC CONTROL (VDC) SYSTEM”
later in this section.) Turn the drive mode select
switch to the SPORT position. “SPORT” appears
in the vehicle information display for 2 seconds.
NOTE:
In the SPORT mode, fuel economy may be re-
duced.
SNOW MODE
Used on snowy roads or slippery areas. When
the SNOW mode is activated, engine output is
controlled to avoid wheel spin. Turn the SNOW
mode off for normal driving. Turn the drive
mode select switch to the SNOW position.
“SNOW” appears in the vehicle information
display for 2 seconds.
ECO MODE
Adjusts engine and transmission points to en-
hance fuel economy.
NOTE:
Selecting this drive mode will not necessarily
improve fuel economy as many driving factors
influence its effectiveness.
Operation
Turn the drive mode select switch to the ECO
position. “ECO” appears in the vehicle informa-
tion display for 2 seconds and the ECO drive
indicator light illuminates on the instrument
panel.
When the accelerator pedal is depressed within
the range of economy drive, the ECO drive
indicator light illuminates in green. When the
accelerator pedal is depressed above the range
of economy drive, the color of the ECO drive indicator light changes to orange. For ECO pedal
system equipped models see “ECO pedal sys-
tem” later in this section.
The ECO drive indicator light will not illuminate
in the following cases:
●
When the selector lever is in the R (Reverse)
position.
● When the vehicle speed is below 3 MPH (4.8
km/h) or over 90 MPH (144 km/h).
● When the Intelligent Cruise Control (ICC)
system is operated.
ECO pedal system (if so equipped)
Helps assist the driver to improve fuel economy
by increasing the reaction force of the accelera-
tor pedal. When the ECO drive indicator light is
blinking or turns orange, the ECO pedal system
increases the reaction force of the accelerator
pedal.

When the ECO drive indicator illuminates in
green, the accelerator reaction force is normal.
When the ECO drive indicator light is blinking or
turns orange, the ECO pedal system increases
the reaction force of the accelerator pedal.
The ECO pedal system may not vary accelerator
reaction force under the following conditions:
●When the selector lever is in the N (Neutral)
or R (Reverse) position.
● When Intelligent Cruise Control (ICC) is being
operated.
If the ECO pedal system malfunctions, it will
cancel automatically. The ECO pedal system will
not vary the reaction force of the accelerator
pedal. When the drive mode select switch is rotated
from the ECO mode to another mode (STAN-
DARD, SPORT or SNOW) while the ECO pedal
system is operating, the ECO pedal system
continues to operate until the pedal is released.
If the accelerator pedal is depressed quickly,
the ECO pedal system will not increase the
reaction force of the acceleration pedal. The
ECO pedal system is not designed to prevent
the vehicle from accelerating.
Adjusting the ECO pedal system reaction force :
The ECO pedal system reaction force can be
adjusted. The reaction force setting will be
maintained until the setting is changed even if
the engine is turned off.

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
●This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of the vehicle at all times.
● The system will not operate at speeds below
approximately 45 MPH or if it cannot detect
lane markers.
● If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer. ●
Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The system may not function properly under the
following conditions:
● On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where the discontinued lane mark-
ers are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The LDW system could detect
these items as lane markers.)
● On roads where the traveling lane merges or
separates.
● When the vehicle’s traveling direction does
not align with the lane marker.
● When traveling close to the vehicle in front
of you, which obstructs the lane camera unit
detection range. ●
When rain, snow or dirt adheres to the
windshield in front of the lane camera unit.
● When the headlights are not bright due to
dirt on the lens or if the aiming is not
adjusted properly.
● When strong light enters the lane camera
unit. (For example, the light directly shines
on the front of the vehicle at sunrise or
sunset.)
● When a sudden change in brightness occurs.
(For example, when the vehicle enters or
exits a tunnel or under a bridge.)

LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above. When the vehicle approaches either the
left or the right side of the traveling lane, a
warning chime will sound and the lane depar-
ture warning light (orange) on the instrument
panel will blink to alert the driver.
The warning function will stop when the vehicle
returns inside of the lane markers.
The LDW system is not designed to warn under
the following conditions.
– When you operate the lane change signaland change traveling lanes in the direction of
the signal. (The LDW system will become
operable again approximately 2 seconds af-
ter the lane change signal is turned off.)
– When the vehicle speed lowers to less than approximately 45 MPH (70 km/h).
– When the BSI system activates an audible warning or brake control.
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
The LDW system is automatically turned on
when the engine is started and the warning systems ON indicator
1illuminates on the
switch. You can turn the LDW system off by
pushing the warning systems switch on the
instrument panel. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
Temporary disabled status at high
temperature
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F (40°C) and then started, the LDW
system may be deactivated automatically. The
lane departure warning light (orange) will flash.
When the interior temperature is reduced, the
LDW system will resume operating automati-
cally and the lane departure warning light (or-
ange) will stop flashing.

LANE DEPARTURE PREVENTION (LDP)
SYSTEM
Precautions on LDP system
WARNING
●The LDP system will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of vehicle at all times.
● The LDP system is primarily intended for use
on well-developed freeways or highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
Otherwise, you could lose control of the
vehicle. ●
The LDP system will not operate at speeds
below approximately 45 MPH (70 km/h) or if
it cannot detect lane markers.
● The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
– During bad weather (rain, fog, snow, wind, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving with a tire that is not within normal tire conditions (for example, tire
wear, low tire pressure, installation of
spare tire, tire chains, non-standard
wheels).
– When the vehicle is equipped with non- original brake parts or suspension parts. ●
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel will
illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
properly under the following conditions:
● On roads where there are multiple parallel
lane markers; lane markers that are faded or
not painted clearly; yellow painted lane
markers; non-standard lane markers; lane
markers covered with water, dirt, snow, etc.
● On roads where discontinued lane markers
are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,
