5-6Starting and driving
Please note that the TPMS is not a sub-
stitute for proper tire maintenance, and it is
the driver’s responsibility to maintain correct
tire pressure, even if under-inflation has not
reached the level to trigger illumination of
the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is com-
bined with the low tire pressure telltale.
When the system detects a malfunction, the
telltale will flash for approximately one
minute and then remain continuously illumi-
nated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction
indicator is illuminated, the system may not
be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS
to continue to function properly.Additional information
.Since the spare tire (if so equipped) is not
equipped with the TPMS, the TPMS
does not monitor the tire pressure of
the spare tire.
. The TPMS will activate only when the
vehicle is driven at speeds above 16
MPH (25 km/h). Also, this system may
not detect a sudden drop in tire pressure
(for example a flat tire while driving).
. The low tire pressure warning light does
not automatically turn off when the tire
pressure is adjusted. After the tire is
inflated to the recommended pressure,
the vehicle must be driven at speeds
above 16 MPH (25 km/h) to activate the
TPMS and turn off the low tire pressure
warning light. Use a tire pressure gauge
to check the tire pressure.
. The “Tire Pressure Low - Add Air”
warning appears in the vehicle informa-
tion display when the low tire pressure
warning light is illuminated and low tire
pressure is detected. The “Tire Pressure
Low - Add Air” warning turns off when
the low tire pressure warning light turns
off.
The “Tire Pressure Low - Add Air”
warning does not appear if the low tire
pressure warning light illuminates to
indicate a TPMS malfunction. .
The “Flat Tire - Visit dealer” warning (if
so equipped) appears in the vehicle
information display when the low tire
pressure warning light is illuminated and
one or more flat tires are detected.
. Tire pressure rises and falls depending on
the heat caused by the vehicle’s opera-
tion and the outside temperature. Do not
reduce the tire pressure after driving
because the tire pressure rises after
driving. Low outside temperature can
lower the temperature of the air inside
the tire which can cause a lower tire
inflation pressure. This may cause the
low tire pressure warning light to illumi-
nate. If the warning light illuminates in
low ambient temperature, check the tire
pressure for all four tires.
. You can also check the pressure of all
tires (except the spare tire) in the vehicle
information display. (See “Vehicle infor-
mation display” (P.2-19).)
. After the ignition switch is placed in the
ON position, it may take a period of time
for the tire pressure to be displayed while
the vehicle is driven. Depending on the
radio wave circumstance, tire pressure
may not correctly be displayed.
For additional information, see “Low tire
pressure warning light” (P.2-12) and “Tire
Pressure Monitoring System (TPMS)” (P.6-
3).

5-16Starting and driving
For additional information about the remote
engine start function, see “Remote engine
start” (P.3-20).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 (AT) 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 is in the ON position.
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 placed
in the LOCK, OFF or ACC position.
1. Keep the foot brake pedal depressed andpush 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.
DRIVING THE VEHICLE

5-18Starting and driving
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.
JVS0903X
Paddle shifters (if so equipped)
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, or pulling the right-side or left-
side paddle shifter (if so equipped).
When shifting up, move the shift lever to the
+ (up) side or pull the right-side paddle
shifter (+)
(if so equipped). The transmis-
sion shifts to the higher range.
When shifting down, move the shift lever to
the − (down) side or pull the left-side paddle
shifter (−)
(if so equipped). The transmis- sion 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.
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 seconds.
In the manual shift mode, the shift range is
displayed in the vehicle information display.
Shift ranges up or down one by one as
follows:
1M?
/
2M?
/3M?
/4M?
/ 5M?
/6M?
/ 7M
7M(7th):
Use this position for all normal forward
driving at highway speeds.
6
M(6th) and 5M(5th):
Use these positions when driving up long
slopes, or for engine braking when driving
down long slopes.

4M(4th), 3M(3rd) and 2M(2nd):
Use these positions for hill climbing or engine
braking on downhill grades.
1
M(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 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 the transmission checked
and repaired, if necessary. It is recom-
mended you visit an INFINITI retailer for
this service.

Shift lock release
If the battery charge is low or discharged,
the shift lever may not be moved from the P
(Park) position even with the brake pedal
depressed and the shift lever button pushed.
To move the shift lever, perform the follow-
ing procedure:
1. Push the ignition switch to the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
using a
suitable tool.
4. Push down the shift lock

5. Push the shift lever buttonand move
the shift lever to N (Neutral) position
while holding down the shift lock.
If the lever cannot be moved out of P (Park),
have the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive Shift Control (ASC)
The adaptive shift control system automati-
cally operates when the transmission is in
the D (Drive) position and selects an appro-
priate gear depending on the road conditions
such as uphill, downhill or curving roads.
Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow smooth
driving with a small number of shifts.
Control on downhill roads:
The adaptive shift control system shifts to a
low gear that suits the degree of the slope,
and uses the engine braking to reduce the
number of times that the brake must be
used.
Control on winding roads:
A low gear is maintained on continuous
curves that involve repeated acceleration
and deceleration, so that smooth accelera-
tion is available instantly when the accel- erator pedal is depressed.
NOTE:
.
Adaptive shift control may not operate
when the transmission oil temperature
is low immediately after the start of
driving or when it is very hot.
. During some driving situations, hard
braking for example, the adaptive shift
control may automatically operate. The
transmission may automatically shift to
a lower gear for engine braking. This
increases engine speed but not vehicle
speed. Vehicle speed is controlled by the
accelerator pedal when the vehicle is in
the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes main-
tains a lower gear for a longer period of
time than when adaptive shift control is
not operating. Engine speed will be
higher for a specific vehicle speed while
ASC system is operating than when ASC
is not operating.
NAVI Shift Control (if so equipped)
NAVI Shift Control automatically adjusts the
Automatic Transmission (AT) gear position
in certain situations based on road informa-
tion from the navigation system.
When the navigation system detects that
the vehicle is approaching a curved road, NAVI Shift Control will adjust the gear
position if needed to help the driver run
through the curve smoothly.
Precaution on NAVI shift control:
.
The NAVI Shift Control does not provide
steering input or automated driving on a
curve. It is not a speed limit support
system and will not modify your speed
according to local speed limits.
. The NAVI Shift Control is a convenient
system intended to help the vehicle move
through a curve smoothly. However, the
driver must always drive safely and use
the brake pedal if needed.
. The NAVI Shift Control may be delayed
or not operate properly in the following
situations, because this function uses the
road information provided by the navi-
gation system.
— When the navigation system cannot accurately detect the location of the
vehicle.
— When the vehicle is driving on a road- way that is not recognized by the
navigation system.
— When the actual roadway differs from the map information on the naviga-
tion system due to road construction,
traffic lane obstructions, etc.
. The NAVI Shift Control may not operate
properly in the following situations:

JVS0934X
When the ECO drive indicator illuminates in
green, the accelerator reaction force is
normal. When the ECO drive indicator light
is blinking or remains off, the ECO pedal
system increases the reaction force of the
accelerator pedal.
The ECO pedal system may not vary accel-
erator reaction force under the following
conditions:
.When the shift 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 INFINITI Drive Mode Selector is
rotated from the ECO mode to another
mode (STANDARD, SPORT+ (if so
equipped), SPORT, SNOW or PERSONAL)
while the ECO pedal system is operating, the
ECO pedal system continues to operate until
the accelerator 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.

LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and when the
lane markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the driver
assist system lane indicator (orange) in the
vehicle information display will blink and a
warning chime will sound. Then, the LDP
system will automatically assist the driver to
return the vehicle to the center of the
traveling lane.
NOTE:
.The LDP system is not designed to work
when you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP will not operate or will stop
operating and only a warning chime will
sound under the following conditions.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed.
— When the Intelligent Cruise Control
(ICC), Distance Control Assist (DCA), Blind Spot Intervention (BSI), Blind
Spot Warning (BSW), Predictive For-
ward Collision Warning (PFCW) or
Forward Emergency Braking (FEB)
approach warning occurs.
— When the BSI system activates.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
— When the brake pedal is depressed.
