5-16Starting and driving
your foot off the accelerator pedalby
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.3-19).

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.

approximately 30 minutes after the ignition
switch is turned off. The indicator light may
also illuminate when the vehicle receives
radio waves. This is not a malfunction.
After starting the engine, fully depress the
brake pedal and shift the shift lever from P (Park) to R (Reverse), N (Neutral), D (Drive)
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 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.
D (Drive):
Use this position for all normal forward
driving.

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:
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 these positions 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 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
