AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission
control module to produce maximum effi-
ciency 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 shift lever
button before shifting the shift 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
shift lever.
This automatic transmission model is de-
signed 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 shift 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 shift 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 either P (Park) or R
(Reverse) position while the vehicle is
moving forward and P (Park) or D
(Drive) position while the vehicle is
moving reversing. This could cause an
accident or damage the transmission.
. Do not downshift abruptly on slip-
pery roads. This may cause a loss of
control.
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.
. Except in an emergency, do not shift
to the N (Neutral) position while
driving. Coasting with the transmis-
sion in the N (Neutral) position may
cause serious damage to the trans-
mission.

Shift lever
To move the shift lever,
: Push the button while depressing the brake pedal,
: Push the button,
: Just move the shift lever.
Shifting
The shift lever position indicator light (next
to the shift lever) will be illuminated for
approximately 30 minutes after the ignition
switch is turned off. The indicator light may
also illuminate when the vehicle receives
radio waves. This is not a malfunction.
After starting the engine, fully depress the
brake pedal and shift the shift lever from P (Park) to R (Reverse), N (Neutral), D (Drive)
or Manual shift mode position.
Push the button to shift into P (Park) or R
(Reverse). All other positions can be selected
without pushing the button.
WARNING
Apply the parking brake if the shift lever
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.
CAUTION
Make sure the vehicle is completely
stopped and the transmission is in the
P (Park) position.
P (Park) position:
Use this 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 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 shift
lever to the P (Park) position.
CAUTION
Use this position only when the vehicle is
completely stopped.
R (Reverse):
Use this position to back up. Always be 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 the P (Park) position, the N (Neutral)
position or any drive position to the R
(Reverse) position.
N (Neutral):
Neither forward nor reverse gear is engaged.
The engine can be started in this position.
You may shift to the N (Neutral) position 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.
When shifting up, move the shift lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the shift lever to
the − (down) side. The transmission shifts to
the lower range.
When canceling the manual shift mode,
return the shift lever to the D (Drive)
position. The transmission returns to the
normal driving mode.
In the manual shift mode, the shift range is
displayed in the vehicle information display
between the speedometer and tachometer.
Shift ranges up or down one by one as
follows:
M1?
/M2 ?
/M3?
/M4 ?
/M5?
/M6?
/M7
M7 (7th):
Use this position for all normal forward
driving at highway speeds.
M6 (6th) andM5 (5th):
Use these positions 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 shift lever rapidly to the same
side twice will shift the ranges in succes-
sion.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear. This helps maintain driving per-
formance and reduces the chance of
vehicle damage or loss of control.
. When the transmission does not shift to
the selected gear, the Automatic Trans-
mission (AT) position indicator (in the
vehicle information display) will blink
and the buzzer 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 condi-
tion.
If the vehicle is driven under extreme
conditions, such as excessive wheel spinning
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 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 the transmission checked and re-
paired, if necessary. It is recommended you

LDW SYSTEM OPERATION
The LDW system provides a lane departure
warning function when the vehicle is driven
at speeds of approximately 37 MPH (60
km/h) and above and the lane markings are
clear. When the vehicle approaches either
the left or the right side of the traveling lane,
the steering wheel will vibrate and the LDW
indicator on the vehicle information display
will blink to alert the driver.
The warning function will stop when the
vehicle returns inside of the lane markers.

structs the lane camera unit de-
tection range.
— When rain, snow, dirt or object 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 sun-
set.)
— When a sudden change in bright- ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)
SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A:
If the vehicle is parked in direct sunlight
under high temperature conditions (over
approximately 104°F (40°C)) and then
started, the LDW system may be deacti-
vated automatically, the LDW indicator will
flash and the following message will appear in the vehicle information display.
.
“Not Available: High Camera Temp”
When the interior temperature is reduced,
the LDW system will resume operating
automatically and the LDW indicator will
stop flashing.
Condition B:
The warning function of the LDW system is
not designed to work under the following
conditions:
. When you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDW system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. When the vehicle speed lowers to less
than approximately 37 MPH (60 km/h).
Action to take:
After the above conditions have finished and
the necessary operating conditions are sa-
tisfied, the LDW system will resume.SYSTEM MALFUNCTION
If the LDW system malfunctions, it will
cancel automatically and “Malfunction”
warning message will appear in the vehicle
information display. If the warning message
appears, pull off the road to a safe location
and stop the vehicle. Place the ignition switch in the OFF position and restart the
engine. If the warning message continues to
appear, have the system checked. It is
recommended that you visit an INFINITI
retailer for this service.

.The BSW system cannot detect all
vehicles under all conditions.
. The radar sensors may not be able to
detect and activate BSW when cer-
tain objects are present such as:
— Pedestrians, bicycles, animals.
— Vehicles such as motorcycles, low height vehicles, or high ground
clearance vehicles.
— Oncoming vehicles.
— Vehicles remaining in the detec- tion zone when you accelerate
from a stop.
— A vehicle merging into an adja- cent lane at a speed approxi-
mately the same as your vehicle.
— A vehicle approaching rapidly from behind.
— A vehicle which your vehicle over- takes rapidly.
— A vehicle that passes through the detection zone quickly.
— When overtaking several vehicles in a row, the vehicles after the
first vehicle may not be detected
if they are traveling close to-
gether. .
The radar sensor’s detection zone is
designed based on a standard lane
width. When driving in a wider lane,
the radar sensors may not detect
vehicles in an adjacent lane. When
driving in a narrow lane, the radar
sensors may detect vehicles driving
two lanes away.
. The radar sensors are designed to
ignore most stationary objects, how-
ever objects such as guardrails, walls,
foliage and parked vehicles may oc-
casionally be detected. This is a
normal operation condition.
. The following conditions may reduce
the ability of the radar to detect
other vehicles:
— Severe weather
— Road spray
— Ice/frost/dirt build-up on the vehicle
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint near
the radar sensors. These conditions
may reduce the ability of the radar to
detect other vehicles.
. When towing a trailer or other ve-
hicle, turn the BSW system off to
prevent the occurrence of an unex- pected accident resulting from sud-
den system operation.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the radar
sensors.
NOTE:
If the BSW system stops working, the Blind
Spot Intervention
®(BSI) system (if so
equipped) will also stop working.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
