REMOTE KEYLESS ENTRY SYSTEM

WARNING
To avoid risk of injury or death, do not
use the remote engine start function
when the vehicle is in an enclosed area
such as a garage.
JVP0445X
The remote engine startbutton is on the
Intelligent Key if the vehicle has remote
engine start function. This function allows
the engine to start from outside the vehicle.
Some systems, such as the air conditioner
system, will turn on during a remote engine
start, if the system was on the last time the
ignition switch was turned off.
Laws in some local communities may restrict
the use of remote engine starters. For
example, some laws require a person using
remote engine start to have the vehicle in
view. Check local regulations for any re-
quirements.
Other conditions may affect the remote
engine start function. See “Conditions the remote engine start will not work” (P.3-20).
Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-7) for additional
information.
REMOTE ENGINE START OPER-
ATING RANGE
The remote engine start function can only be
used when the Intelligent Key is within the
specified operating range from the vehicle.
When the Intelligent Key battery is dis-
charged or other strong radio wave sources
are present near the operating location, the
Intelligent Key operating range becomes
narrower, and the Intelligent Key may not
function properly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE
To use the remote engine start function to
start the engine, perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Push the “LOCK”
button to lock all
doors.

SET/memory switches
The automatic drive positioner system has
three features:
. Entry/exit function
. Memory storage
. Setting memory function
ENTRY/EXIT FUNCTION
This system is designed so that the driver’s
seat and steering column will automatically
move when the automatic transmission shift
lever is in the P (Park) position. This allows
the driver to get into and out of the driver’s
seat more easily.
The driver’s seat will slide backward and the
steering wheel will move up when the
driver’s door is opened with the ignition
switch in the LOCK position.
The driver’s seat and steering wheel will
return to the previous positions when the
ignition switch is pushed to the ACC posi-
tion.
The driver’s seat will not return to the
previous positions if the seat or steering
adjusting switch is operated when the seat is
at the exit position.
Cancel or activate entry/exit func-
tion
The shift lever must be in the P (Park)
position with the ignition switch in the OFF
position.
The entry/exit function can be activated or
canceled by pressing and holding the SET
switch for more than 10 seconds.
The entry/exit function can also be acti-
vated or canceled if the “Lift Steering upon Exit” key or “Slide Driver Seat Back on Exit”
key is turned to ON or OFF in the [Settings]
menu on the lower display. (See INFINITI
InTouch
TMOwner’s Manual.)
Initialize entry/exit function
If the battery cable is disconnected, or if the
fuse opens, the entry/exit function will not
work though this function was set on before.
In such a case, after connecting the battery
or replacing with a new fuse, open and close
the driver’s door more than two times after
the ignition switch is turned from the ON
position to the LOCK position. The entry/
exit function will be activated.
MEMORY STORAGE
Two positions for the driver’s seat, steering
column and outside mirrors can be stored in
the automatic drive positioner memory.
Follow these procedures to use the memory
system.
1. Move the shift lever to the P (Park)
position.
2. Adjust the driver’s seat, steering column and outside mirrors to the desired posi-
tions by manually operating each adjust-
ing switch. For additional information,
see “Seats” (P.1-3) and “Tilt/telescopic
steering” (P.3-29) and “Outside mirrors”
(P.3-37).
AUTOMATIC DRIVE POSITIONER

3. Push the SET switch and, within 5seconds, push the memory switch (1 or
2) fully for at least 1 second.
The indicator light for the pushed mem-
ory switch will stay on for approximately
5 seconds after pushing the switch.
When the memory is stored in the
memory switch (1 or 2), a buzzer will
sound.
If memory is stored in the same memory
switch, the previous memory will be
deleted.
Linking Intelligent Key to a stored
memory position
The Intelligent Key can be linked to a stored
memory position with the following proce-
dure.
1. Follow the steps for storing a memoryposition.
2. While the indicator light for the memory switch being set is illuminated for 5
seconds, push the
button on the
Intelligent Key. If the indicator light
blinks, the Intelligent Key is linked to
that memory setting.
Push the ignition switch to the OFF position,
and then push the
button on the
Intelligent Key. The driver’s seat, steering
wheel and outside mirrors will move to the memorized position.
Confirming memory storage
.
Push the ignition switch to the ON
position and push the SET switch. If the
main memory has not been stored, the
indicator light will come on for approxi-
mately 0.5 second. When the memory
has stored in position, the indicator light
will stay on for approximately 5 seconds.
. If the battery cable is disconnected, or if
the fuse opens, the memory will be
canceled. In this case, reset the desired
position using the previous procedure.
. If optional Intelligent Keys are added to
your vehicle, the memory storage proce-
dure to switch 1 or 2 and linking
Intelligent Key procedure to a stored
memory position should be performed
again for each Intelligent Key. For addi-
tional Intelligent Key information, see
“Keys” (P.3-2).
Selecting the memorized position
1. Move the shift lever to the P (Park) position.
2. Use one of the following methods to move the driver’s seat, the outside
mirrors and the steering wheel.
.Push the memory switch (1 or 2) fully
for at least 1 second. The driver’s seat, steering column and
outside mirrors will move to the memor-
ized position or to the exit position when
the entry/exit function is set to active
with the indicator light flashing, and then
the light will stay on for approximately 5
seconds.
SETTING MEMORY FUNCTION
The status of the following settings can be
linked to the Intelligent Key and the memor-
ized settings can be available for each
Intelligent Key.
.
Air conditioner system
. Navigation system
. Audio system
To use the memory function, lock the doors
with the Intelligent Key that is linked to the
settings.
To enable the memorized settings:
1. Carry the Intelligent Key that is linked to the settings, and unlock the doors by
pushing the driver’s door handle request
switch or “UNLOCK”
button on the
Intelligent Key.
2. Place the ignition switch in the ON position. The memorized settings are
available.
