5-14Starting and driving
1. Apply the parking brake.
2. Move the selector lever to the P (Park)or N (Neutral) position. (P is recom-
mended.)
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 position. 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 inextremely cold weather or when
restarting, 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 startbecause it is flooded, depress the
accelerator pedal all the way to the
floor and hold it. Push the ignition
switch to the ON position 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
engine 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 of 2 - 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.
5. To stop the engine, shift the selector lever to the P (Park) position and push
the ignition switch to the OFF position.
STARTING THE ENGINE

AUTOMATIC TRANSMISSION
7 speed 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), DS (Drive Sport) 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), DS
(Drive Sport) 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), D (Drive) or DS (Drive
Sport) 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.

Shifting
After starting the engine, fully depress the
brake pedal and shift the selector lever
from P (Park) to R (Reverse), N (Neutral), D
(Drive), DS (Drive Sport) 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 selector 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 selector position when the vehicle
is parked or when starting the engine.
Make sure the vehicle is completely
stopped. The brake pedal must be de-
pressed 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
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 selector lever button pushed in to
move the selector 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 en-
gaged. 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.

DS (Drive Sport) mode
When the selector lever is shifted from the
D (Drive) position to the manual shift gate,
the transmission enters the DS (Drive
Sport) mode.
Moving the selector lever to the DS (Drive
Sport) position allows you to enjoy com-
fortable driving 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
selector lever to the D (Drive) position. The
transmission returns to the normal driving
mode.
SSD0732
Paddle shifters (If so equipped)
Manual shift mode
When the selector lever is in the DS (Drive
Sport) position, 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.
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 (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 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 this position 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
Starting and driving5-17

5-18Starting and 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 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.

Shift lock release
If the battery charge is low or discharged,
the selector lever may not be moved from
the P (Park) position even with the brake
pedal depressed and the selector lever
button pushed.
To move the selector lever, perform the
following procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover

Push the ignition switch to the ON posi-
tion. Now the vehicle may be moved to the
desired location.
If the lever cannot be moved out of P
(Park), have an INFINITI retailer check the
automatic transmission system as soon as
possible.
Adaptive shift control (ASC)
The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) and "DS" (Drive Sport)
position and selects an appropriate 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
Starting and driving5-19

5-20Starting and driving
maintains 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.WARNING
.Be sure the parking brake is fully
released before driving. Failure to do so
can cause brake failure and lead to an
accident.
. Do not release the parking brake from
outside the vehicle.
. Do not use the gear shift in place of the
parking brake. When parking, be sure
the parking brake is fully engaged.
. Do not leave children unattended in a
vehicle. They could release the parking
brake and cause an accident.

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.)
