tions, see “High voltage components”
(P.Hybrid System-9). To avoid per-
sonal injury, never touch high-vol-
tage wiring, connectors, and other
high-voltage parts, such as electric
motor inverter and Lithium ion (Li-
ion) battery. An electric shock may
occur if exposed electric wires are
visible when viewed from inside or
outside of your vehicle. Therefore,
never touch exposed electric wires.
. If the vehicle receives a strong impact
to the floor while driving, stop the
vehicle in a safe location and check
the floor.
. Inspect the ground under the vehicle.
If liquid has leaked onto the ground,
the fuel system may have been da- maged. Leave the vehicle as soon as
possible.
. Leaks or damage to the Li-ion bat-
tery may result in a fire. If you
discover them, contact emergency
services immediately. Since the fluid
leak may be lithium organic electro-
lyte from the Li-ion battery, never
touch the fluid leak inside or outside
the vehicle. If the fluid contacts your
skin or eyes, wash it off immediately
with a large amount of water and
receive immediate medical attention
to help avoid serious injury.
. If a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Only use a type ABC, BC or C fire
extinguisher that is meant for use on
electrical fires. Using water or the
incorrect fire extinguisher can result
in serious injury or death from elec-
trical shock.
. If you are not able to safely assess
the vehicle due to vehicle damage, do
not touch the vehicle. Leave the

WARNING
.Radio waves could adversely affect
electric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment man-
ufacturer for the possible influences
before use.
. The Intelligent Key transmits radio
waves when the buttons are pushed.
The FAA advises that the radio
waves may affect aircraft navigation
and communication systems. Do not
operate the Intelligent Key while on
an airplane. Make sure the buttons
are not operated unintentionally
when the unit is stored during a
flight.
The Intelligent Key system can operate all
the doors and the trunk lid using the remote
controller function or pushing the request
switch on the vehicle without taking the key
out from a pocket or purse. The operating
environment and/or conditions may affect
the Intelligent Key system operation.
Be sure to read the following before using
the Intelligent Key system.
CAUTION
. Be sure to carry the Intelligent Key
with you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a personal
computer. .
When the vehicle is parked near a parking
meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery dis-
charge” (P.5-12) to start the Direct Re-
sponse Hybrid
®System.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-21).
For models with a steering wheel lock
mechanism: Because the steering wheel is
locked electrically, unlocking the steering
wheel with the ignition switch in the LOCK
position is impossible when the vehicle
battery is completely discharged. Pay special
attention that the vehicle battery is not
completely discharged.
Pre-driving checks and adjustments3-7
INTELLIGENT KEY SYSTEM

When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key system’s operating range becomes nar-
rower, and the Intelligent Key may not
function properly.
The operating range is within 31.50 in (80
cm) from each request switch
.
If the Intelligent Key is too close to the door
glass, handle or rear bumper the request
switches may not function.
When the Intelligent Key is within the
operating range, it is possible for anyone

push the request switch to lock/unlock the
doors and open the trunk lid.
SPA2407
DOOR LOCKS/UNLOCKS PRE-
CAUTION
. Do not push the door handle request
switch with the Intelligent Key held in
your hand as illustrated. The close dis-
tance to the door handle will cause the
Intelligent Key system to have difficulty
recognizing that the Intelligent Key is
outside the vehicle.
. After locking with the door handle re-
quest switch, verify the doors are se-
curely locked by testing them.
. To prevent the Intelligent Key from being
left inside the vehicle or the trunk, make

Shift lock release
If the 12-volt battery charge is low or
discharged, the shift lever may not be moved
from the P (Park) position even with the
brake pedal depressed and the shift lever
button pushed.
To move the shift lever, perform the follow-
ing procedure:
1. Push the ignition switch to the OFF orLOCK position.
2. Apply the parking brake.
3. Remove the shift lock cover
using a
suitable tool.
4. Push down the shift lock
as illustrated. 5. Push the shift lever button
and move
the shift lever to N (Neutral) position
while 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 comple-
tely, 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 the automatic transmission system
checked as soon as possible. It is recom-
mended you visit an INFINITI retailer for this
service.
Adaptive shift control (ASC)
The adaptive shift control system automati-
cally 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 the
accelerator pedal when the vehicle is in
the Adaptive shift control mode.
. When the adaptive shift control oper-
ates, the transmission sometimes main-
tains a lower gear for a longer period of
time than when adaptive shift control is
not operating. Engine speed will be
