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 en-
gine 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 of2-3
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.
AUTOMATIC TRANSMISSION
7 speed automatic transmission
The automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum efficiency and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. 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 (Re-
verse), 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 posi-
tion 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 (Re-
verse), 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 cau-
tion 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.
DRIVING THE VEHICLE
5-12Starting and driving

●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.
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
To move the selector lever,
: Push the button while depressing the
brake pedal,
: Push the button,
: Just move the selector lever.
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 depressed 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.Selector lever

CAUTION
Use this position only when the vehicle is com-
pletely 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 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.
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 transmission
changes to the “sporty” driving shift operation, creating a more aggressive acceleration feeling
than the D (Drive) mode and providing a gear
change sensation 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 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. 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 economy.
5-14Starting and driving

●Moving the selector lever rapidly to the same
side twice will shift the ranges in succes-
sion. However, if this motion is done rapidly,
the second shifting may not be completed
properly.
● In the manual shift mode, the transmission
may not shift to the selected gear. This helps
maintain driving performance and reduces
the chance of vehicle damage or loss of con-
trol.
● In the manual shift mode, the transmission
automatically shifts down to 1st gear before
the vehicle comes to a stop. When accelerat-
ing 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, depend-
ing 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 spinning and subse-
quent 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 re-
turn 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 de-
pressed and the selector lever button pushed.
To move the selector 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

5-16Starting and driving

The Lane Departure Warning (LDW)
system/Lane Departure Prevention (LDP) sys-
tem will operate when the vehicle is driven at
speeds of approximately 45 MPH (72 km/h) and
above, and when it is traveling close to either
the left or the right of a traveling lane.
Each system functions as follows:
●Lane Departure Warning (LDW) system —
warns the driver with a warning light and
chime that the vehicle is beginning to leave
the driving lane.
● Lane Departure Prevention (LDP) system —
warns the driver by a warning light and
chime, and helps assist the driver to return
the vehicle to the center of the traveling lane
by applying brake control to the left or right
wheels individually (for a short period of
time). The LDW and LDP systems monitor the lane
markers on the traveling lane using the camera
unit
1located inside the front map light cover.
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
2on the instrument 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.
To turn on the LDW system, push the warning
systems switch

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
●This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility 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 can-
not detect lane markers.
● If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer. ●
Excessive noise will interfere with the warn-
ing 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-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where the discontinued lane mark-
ers are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing 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.)
5-18Starting and driving

LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above. When the vehicle approaches either the
left or the right side of the traveling lane, a
warning chime will sound and the lane depar-
ture warning light (orange) on the instrument
panel will blink to alert the driver.
The warning function will stop when the vehicle
returns inside of the lane markers.
When you operate the lane change signal and
change traveling lanes in the direction of the
signal, the LDW system temporarily suspends
operation. It will become operable again ap-
proximately 2 seconds after the lane change
signal is turned off.
When the vehicle speed lowers to less than
approximately 45 MPH (70 km/h), the LDW
system will not provide a warning.
The LDW system has an automatic setting mode
and a manual setting mode. The setting mode
can be changed. In the automatic setting mode,
the LDW system is automatically turned on
when the ignition switch is pushed to the ON
position. When the LDW system is on, the
warning systems ON indicator
1on the warn-
ing systems switch illuminates. To cancel the LDW system, push the warning systems switch.
The warning systems ON indicator will turn off.
To turn on the system, push the warning sys-
tems switch again. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
In the manual setting mode, you need to push
the warning systems switch to turn on the
system after the ignition switch is pushed to the
ON position.
The setting mode can be changed using the
warning systems switch. To change the setting
mode, push and hold the warning systems
switch for more than 4 seconds when the
warning systems ON indicator is off. When the
mode is changed, a chime sounds and the lane
departure warning light (orange) flashes.
Temporary disabled status at high
temperature
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F (40°C) and then started, the LDW
system may be deactivated automatically. The
lane departure warning light (orange) on the
switch will flash.
