switch to the OFF position, depending
on the driving conditions (VK56VD
engine models).AUTOMATIC TRANSMISSION
The automatic transmission in your vehicle
is electronically controlled by a transmis-
sion control module to produce maximum
efficiency and smooth operation.
Shown on the following pages are the
recommended operating procedures for
this transmission. 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 (Reverse), 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 position 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
and push 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 (Reverse), D (Drive) or
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
caution 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.
DRIVING THE VEHICLE

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.
. Except in an emergency, do not shift to
the N (Neutral) position while driving.
Doing so can cause a loss of engine
braking which may result in a collision,
serious personal injury or death. In
addition, coasting with the transmission
in the N (Neutral) position may cause
serious damage to the transmission.

Paddle shifters (if so equipped)
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 manually 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 transmission 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 tempora-
rily. 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 seconds.
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 econ-
omy.
. Moving the selector lever rapidly to the
same side twice will shift the ranges in
succession.
. 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
vehicle damage or loss of control.
When this situation occurs, the Auto-
matic Transmission (AT) position indi-
cator light (on the dot matrix liquid
crystal display) will blink and the
chime will sound.
. In the manual shift mode, the transmis-
sion automatically shifts down to 1st gear before the vehicle comes to a
stop. When accelerating again, it is
necessary to shift up to the desired
range.Accelerator downshift
—In D (Drive)
position —
For passing or hill climbing, fully depress
the accelerator pedal to the floor. This
shifts the transmission down into the lower
gear, depending on the vehicle speed.
Fail-safe
When the fail-safe operation occurs, note
that the transmission will be locked in any
of the forward gears according to the
condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning and subsequent hard braking, the
fail-safe system may be activated. This will
occur even if all electrical circuits are
functioning properly. In this case, push
the ignition switch to the OFF position and
wait for 3 seconds. Then push the ignition
switch back to the ON position. The vehicle
should return to its normal operating
condition. If it does not return to its
normal operating condition, have an
INFINITI retailer check the transmission and repair if necessary.

sarily 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
information 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 system ”
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 accelerator pedal. When the ECO
drive indicator light is blinking or turns
orange, the ECO pedal system increases
the reaction force of the accelerator pedal.
SSD1041
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 follow-
ing 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 (STANDARD, 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 accelera-
tion 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.

The LDW and LDP systems monitor the lane
markers on the traveling lane using the
camera unit
*1located above the inside
mirror. When the camera unit detects that
the vehicle is traveling close to either the
left or the right of the traveling lane, the
lane departure warning light on the instru-
ment panel blinks in orange and a warning
chime sounds. When the LDP system is on,
it will automatically apply the brakes for a
short period of time, using the function of
the Vehicle Dynamic Control (VDC) system.
LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
. This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It
is the driver ’s responsibility 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
cancel automatically, and the lane de-
parture warning light (orange) will illu-
minate.
. If the lane departure warning light
(orange) illuminates, pull off the road
to a safe location and stop the vehicle.
Turn the engine off and restart the
engine. If the lane departure warning
light (orange) continues to illuminate,
have the system checked by an INFINITI
retailer.
. Excessive noise will interfere with the
warning 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-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where the discontinued lane
markers are still detectable. .
On roads where there are sharp curves.
. On roads where there are sharply
contrasting 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.)
