INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions
interfere with the Intelligent Key operation,
start the hybrid system according to the
following procedure:
1. Move the selector lever to the P (Park)position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.) 4. Push the ignition switch while depres-
sing the brake pedal within 10 seconds
after the chime sounds. The hybrid
system will start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the hybrid
system is started by the above proce-
dures, the Intelligent Key battery dis-
charge indicator appears on the dot
matrix liquid crystal display even if the
Intelligent Key is inside the vehicle.
This is not a malfunction. To turn off
the Intelligent Key battery discharge
indicator, touch the ignition switch
with the Intelligent Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Intelligent
Key battery replacement” in the“8.
Maintenance and do-it-yourself” sec-
tion.) .
Make sure the area around the vehicle
is 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 appear-
ance and condition. Also check tires for
proper inflation.
. Lock all doors.
. Position seat and adjust head re-
straints.
. Adjust inside and outside mirrors.
. Fasten seat belts and ask all passen-
gers to do likewise.
. Check the operation of warning lights
when the ignition switch is pushed to
the ON position. (See “Warning/indica-
tor lights and audible reminders” in the
“2. Instruments and controls” section.)
BEFORE STARTING THE INFINITI DIRECT
RESPONSE HYBRIDTMSYSTEM

1. Apply the parking brake.
2. Move the shift selector to P (Park)position.
The INFINITI Direct Response Hybrid
TM
System is designed not to operate if
the shift selector is not in the P (Park)
position.
3. Depress the brake pedal and push the ignition switch to start the hybrid
system. The READY to drive indicator
light will illuminate on the meter.
When starting the hybrid system at
very low outside temperatures, the
READY to drive indicator light will flash
and it may take longer for the READY to
drive indicator light to illuminate.
. The hybrid system may not start even
with the READY to drive indicator light
illuminated. Once the READY to drive
indicator light is illuminated you may
begin driving the vehicle.
. You may hear a sound in the engine
compartment when the brake pedal is
depressed with the hybrid system off.
This does not indicate a problem.
NOTE:
Care should be taken to avoid situations
that can lead to potential 12-volt battery discharge and potential no-start condi-
tions such as:
1.
Installation or extended use of electro-
nic accessories that consume 12-volt
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 12-volt battery may
need to be charged to maintain 12-volt
battery health.
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 INFINITI Direct Response
HybridTMSystem, 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) 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 depressedand 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) 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) or D (Drive) 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.
. 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.

Selector lever
To move the selector lever,
: Push the button while depressing the brake pedal,
: Push the button,
: Just move the selector lever.
Shifting
After starting the hybrid system, fully
depress the brake pedal and shift the
selector 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.

5-16Starting and driving
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.
. 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
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 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
condition.
If the vehicle is driven under extreme
conditions, such as excessive wheel spin-
ning 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 ignition 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 repair if necessary.

SSD0974
Shift lock release
If the 12-volt battery charge is low or
discharged, the selector lever may not be
moved from the P (Park) position even with
the brake pedal depressed and the selector
lever button pushed.
To move the selector lever, perform the
following procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
*Ausing a
suitable tool. 4. Push down the shift lock
*Bas
illustrated.
5. Push the selector lever button
*Cand
move the selector lever to N (Neutral)
position
*Dwhile holding down the
shift lock.
Push the ignition switch to the ON position
to unlock the steering wheel (if so
equipped). Now the vehicle may be moved
to the desired location.
For models with a steering wheel lock
mechanism:
If the 12-volt battery is discharged com-
pletely, the steering wheel cannot be
unlocked. Do not move the vehicle with
the steering wheel locked.
If the lever cannot be moved out of P
(Park), have an INFINITI retailer check the
automatic transmission system as soon as
possible.
Adaptive shift control (ASC)
The adaptive shift control system automa-
tically operates when the transmission is
in the "D" (drive) position and selects an
appropriate gear depending on the road
conditions such as uphill, downhill or
curving roads. Control on uphill and curving roads:
A low gear is maintained that suits the
degree of the slope or curve to allow
smooth driving with a small number of
shifts.
Control on downhill roads:
The adaptive shift control system shifts to
a low gear that suits the degree of the
slope 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
Starting and driving5-17

5-18Starting and driving
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.

pushed again, the system will turn on and
the IBA OFF indicator light will turn off.
The IBA system will remain in the last ON
or OFF state it was left in until it is
manually changed by pressing the IBA
OFF switch.
Illumination of the IBA OFF indicator light
without the warning chime sound is an
indication that the IBA system is tempora-
rily unavailable. It will occur under the
following conditions:
.When driving into a strong light (for
example, sunlight)
The IBA OFF indicator light will turn off
when the system returns to its normal
operating conditions.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system” earlier in
this section.
CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble. .
Accelerate slowly and smoothly. Main-
tain cruising speeds with a constant
accelerator position.
. Drive at moderate speeds on the high-
way.
. Avoid unnecessary stopping and brak-
ing. Keep a safe distance behind other
vehicles.
. Select a gear range suitable to road
conditions.
. Avoid unnecessary prolonged engine
idling.
. Keep your engine tuned up.
. Follow the recommended periodic main-
tenance schedule.
. Keep the tires inflated at the correct
pressure. Improper tire pressure will
increase wear and waste fuel.
. Make sure the front wheels are properly
aligned. Improper alignment will cause
premature tire wear and lower fuel
economy.
. Climate control operation lowers fuel
economy. Use the air conditioner only
when necessary.
. When cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.

WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric pumps, hydraulic solenoids and a
computer. The computer has a built-in
diagnostic feature that tests the system
each time you start the hybrid system and
move the vehicle at a low speed in forward
or reverse. When the self-test occurs, you
may hear a“clunk”noise and/or feel a
pulsation in the brake pedal. This is normal
and does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS
warning light on the instrument panel.
The brake system then operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h).
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic
pressure. This action is similar to pumping
the brakes very quickly. You may feel a
pulsation in the brake pedal and hear a
noise from under the hood or feel a
vibration from the actuator when it is
operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving. The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, the VDC system helps
to perform the following functions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine or
mortor output to reduce drive wheel
slip based on vehicle speed (traction
control function).
. Controls brake pressure at individual
wheels and engine or motor output to
help the driver maintain control of the
vehicle in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due
to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
