clear.

. Check fluid levels such as engine oil,

coolant, brake fluid and window washer
fluid as frequently as possible, or at least
whenever you refuel.

. Check that all windows and lights are

clean.

. Visually inspect tires for their appearance

and condition. Also check tires for proper
inflation.

. Lock all doors.

. Position seat and adjust head restraints/

headrests.

. Adjust inside and outside mirrors.

. Fasten seat belts and ask all passengers

to do likewise.

. Check the operation of warning lights

when the ignition switch is pushed to the
ON position. (See “Warning lights, in-
dicator lights and audible reminders”
(P.2-11).)

1. Apply the parking brake.
2. Move the shift lever to the P (Park) or N

(Neutral) position. (P is recommended.)
The starter is designed not to operate

your foot off the accelerator pedal by
depressing the brake pedal and push-
ing the push-button ignition 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 crank-
ing 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 shut-
ting it off. Starting and stopping the
engine over a short period of time may
make the vehicle more difficult to start.
When racing the engine up to 4,000 rpm
or more under the no load condition, the
engine will enter the fuel cut mode.

5. To stop the engine, shift the shift lever to

the P (Park) position and push the
ignition switch to the OFF position.

In preparation for the next engine start, the
engine may have a slightly delayed shutoff
after placing the ignition switch in the OFF
position, depending on the driving condi-
tions.

NOTE:
Care should be taken to avoid situations
that can lead to potential battery discharge
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.

REMOTE START (if so equipped)

Vehicles started with the remote engine
start function require the ignition switch to
be placed in the ON position before the shift
lever can be moved from the P (Park)
position. To place the ignition switch in the
ON position, perform the following steps:
1. Make sure that the Intelligent Key is on

you.

2. Depress the brake pedal.
3. Push the ignition switch once to the ON

position.

For additional information about the remote
engine start function, see “Remote engine
start” (P.3-18).

ENGINE PROTECTION MODE

The engine has an engine protection mode to
reduce the chance of damage if the coolant
temperature becomes too high (for example,
when climbing steep grades in high tem-
perature with heavy loads, such as when
towing a trailer).
When the engine temperature reaches a
certain level:
. The engine coolant temperature gauge

will move toward the H position.

. Engine power may be reduced.

. The air conditioning cooling function may

be automatically turned OFF for a short
time (the blower will continue to oper-
ate).

Engine power and, under some conditions,
vehicle speed will decrease. Vehicle speed
can be controlled with the accelerator pedal,
but the vehicle may not accelerate at the
desired speed. The transmission will down-
shift or upshift as it reaches prescribed shift
points. You can also shift manually.
As driving conditions change and engine
coolant temperature is reduced, vehicle
speed can be increased using the accelerator
pedal, and air conditioning cooling function
will automatically be turned back ON.

If:
1. The engine coolant temperature is not

reduced.

2. The air conditioning cooling function

does not turn back ON.

3. The engine oil pressure warning light

illuminates or engine coolant tempera-
ture gauge does not return to the normal
range from the H position, this may
indicate a malfunction. Move the vehicle
off the road to a safe area and allow the
engine to cool. If after checking the oil
and coolant, the

remains on or

engine coolant temperature does not
return to the normal range, do not
continue to drive. It is recommended
you contact an INFINITI retailer.

The Malfunction Indicator Light (MIL)
may also come ON. You do not need to have
your vehicle towed, unless it remains on, but
have it inspected soon. It is recommended
you visit an INFINITI retailer for this service.
See “Warning lights, indicator lights and
audible reminders” (P.2-11).

WARNING

Overheating can result in reduced engine
power and vehicle speed. The reduced
speed may be lower than other traffic,

which could increase the chance of a
collision. Be especially careful when
driving. If the vehicle cannot maintain a
safe driving speed, pull to the side of the
road in a safe area. Allow the engine to
cool and return to normal operation. See
“If your vehicle overheats” (P.6-14).

CAUTION

Running the engine with the engine oil
pressure warning light on could cause
serious damage to the engine almost
immediately. Such damage is not cov-
ered by warranty. Turn off the engine as
soon as it is safe to do so.

AUTOMATIC TRANSMISSION

7 speed 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 model is de-
signed 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 shift 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 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.

CAUTION

. To avoid possible damage to your

vehicle; 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.

. Except in an emergency, do not shift

to the N (Neutral) position while
driving. Coasting with the transmis-
sion in the N (Neutral) position may
cause serious damage to the trans-
mission.

WARNING

Apply the parking brake if the shift 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 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 shift lever
button pushed in to move the shift 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 shift
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 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.

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.
When shifting up, move the shift lever to the
+ (up) side. The transmission shifts to the
higher range.
When shifting down, move the shift lever to
the − (down) side. The transmission 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.
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:

Use these positions for hill climbing or engine
braking on downhill grades.

M

1 (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 light (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 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 re-
paired, if necessary. It is recommended you

visit an INFINITI retailer for this service.

WARNING

Failure to follow the warnings and
instructions for proper use of the LDW
and LDP systems could result in serious
personal injury or death.
. The LDW and LDP systems 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 LDP system may activate if you

change lanes without first activating
your turn signal or, for example, if a
construction zone directs traffic to
cross an existing lane marker. If this
occurs, you may need to apply cor-
rective steering to complete your lane
change.

. Because the LDP system may not

activate under the road, weather,
and lane marker conditions described
in this section, it may not activate
every time your vehicle begins to
leave its lane and you will need to
apply corrective steering.

operate the vehicle in accordance with
these system limitations could result in
serious injury or death.
. The system will not operate at speeds

below 45 MPH (70 km/h) or if it
cannot detect lane markers.

. The LDP system is primarily intended

for use on well-developed freeways
or highways. It may not detect the
lane markers in certain roads, weath-
er or driving conditions.

. Do not use the LDP system under the

following conditions as it may not
function properly:

— During bad weather (rain, fog,

snow, etc.).

— When driving on slippery roads,

such as on ice or snow, etc.

— When driving on winding or un-

even roads.

— When there is a lane closure due

to road repairs.

— When driving in a makeshift or

temporary lane.

— When driving on roads where the

lane width is too narrow.

— When driving without normal tire

conditions (for example, tire wear,
low tire pressure, installation of
spare tire, tire chains, non-stan-
dard wheels).

— When the vehicle is equipped with

non-original brake parts or sus-
pension parts.

— When you are towing a trailer or

other vehicle.

. The camera may not detect lane

markers in the following situations
and the LDW and LDP systems may
not operate properly.

— On roads where there are multi-

ple 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 markers are still detectable.

— On roads where there are sharp

curves.

— On roads where there are sharply

contrasting objects, such as sha-
dows, snow, water, wheel ruts,
seams or lines remaining after
road repairs. (The LDW and LDP
systems could detect these items
as lane markers.)

— On roads where the traveling lane

merges or separates.

— When the vehicle’s traveling di-

rection does not align with the
lane marker.

— When traveling close to the ve-

hicle in front of you, which ob-
structs 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 sun-
set.)

— When a sudden change in bright-

ness occurs. (For example, when
the vehicle enters or exits a tunnel
or under a bridge.)

. Excessive noise will interfere with the

warning chime sound, and the chime
may not be heard.
