ALL-WHEEL DRIVE (AWD) DRIVING
SAFETY PRECAUTIONS (for AWD
models)
WARNING
.Do not drive beyond the performance
capability of the tires, even with AWD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
. Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.
. This vehicle is not designed for offroad
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
. For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any D (Drive) or R (Reverse) position with
the engine running. Doing so may result
in drivetrain damage or unexpected
vehicle movement which could result in serious vehicle damage or personal
injury.
. Do not attempt to test an AWD equipped
vehicle on a 2-wheel dynamometer,
(such as the dynamometers used by
some states for emissions testing), or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with AWD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or
personal injury.
. When a wheel is off the ground due to an
unlevel surface, do not spin the wheel
excessively.
WARNING
Do not operate the push-button ignition
switch while driving the vehicle except in an
emergency. (The engine will stop when the
ignition switch is pushed 3 consecutive
times or the ignition switch is pushed and
held for more than 2 seconds.) If the engine
stops while the vehicle is being driven, this
could lead to a crash and serious injury.
Before operating the push-button ignition
switch, be sure to move the selector lever
to the P (Park) position.

BEFORE STARTING THE ENGINE

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.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of electro-
nic accessories that consume battery
power when the engine is not running
(Phone chargers, GPS, DVD players,
etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.

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
.
Except in an emergency, do not shift to
the N (Neutral) position while driving.
Coasting with the transmission in the N
(Neutral) position may cause serious
damage to the transmission.
. 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.

: Just move the selector lever.
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.
Starting and driving5-15

5-16Starting and driving
DS (Drive Sport) mode
Move the selector lever from D (Drive) to
the left into the manual shift gate. The
transmission position indicator in the
meter shows“DS”.
In the DS (Drive Sport) mode, the transmis-
sion changes to the “sporty”driving shift
operation, creating a more aggressive
acceleration feeling than the D (Drive)
mode and providing a gear change sensa-
tion when the driver accelerates quickly.
When the driver selects the manual shift
mode using the selector lever during the
DS (Drive Sport) mode operation, the driver
must move the selector lever from DS
(Drive Sport) to D (Drive) and back again
to re-select the DS (Drive Sport) mode.
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.
When shifting up, move the selector lever
to the + (up) side. The transmission shifts
to the higher range.
When shifting down, move the selector lever to the
−(down) side. 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.
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. However, if this motion is
done rapidly, the second shifting may
not be completed properly.
. In the manual shift mode, the transmis-
sion may not shift to the selected gear
or may automatically shift to the other
gear depending on conditions. This
helps maintain driving performance
and reduces the chance of vehicle
damage or loss of control.
. When the transmission does not shift
to the selected gear, the Automatic
Transmission (AT) position indicator
light (on the dot matrix liquid crystal
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

5-18Starting and driving
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 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 (70 km/h)
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.
