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 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.

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 andpush 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.
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.

To move the selector lever,
: Push the button while depressing thebrake 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.
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) :

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.
● Moving the selector lever rapidly to the same
side twice will shift the ranges in succes-
sion.
● 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.
When this situation occurs, the Automatic
Transmission (AT) position indicator light (on
the dot matrix liquid crystal display) will
blink and the chime will sound. ●
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 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 re-
pair 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
Ausing a
suitable tool.

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 or if it cannot 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.)

LANE DEPARTURE PREVENTION (LDP)
SYSTEM
Precautions on LDP system
WARNING
●The LDP system 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 vehicle at all times.
● The LDP system is primarily intended for use
on well-developed freeways or highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
Otherwise, you could lose control of the
vehicle. ●
The LDP system will not operate at speeds
below approximately 45 MPH (72 km/h) or if
it cannot detect lane markers.
● The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
– During bad weather (rain, fog, snow, wind, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving without normal tire condi- tions (for example, tire wear, low tire
pressure, installation of spare tire, tire
chains, non-standard wheels).
– When the vehicle is equipped with non- original brake parts or suspension parts. ●
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel 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 warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
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 discontinued lane markers
are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,

●The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and ICC system dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when:
● the vehicle approaches other vehicles that
are parked or moving slowly.
● the accelerator pedal is depressed, overrid-
ing the system.
