OPERATING RANGE
WARNING
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including entrap-
ment in windows or inadvertent door lock
activation, do not leave children, people
who require the assistance of others or
pets unattended in your vehicle. Addition-
ally, the temperature inside a closed vehicle
on a warm day can quickly become high
enough to cause a significant risk of injury
or death to people and pets.
CAUTION
When the Intelligent Key battery is dis-
charged or other strong radio wave
sources are present near the operating lo-
cation, the Intelligent Key operating range
becomes narrower, and the Intelligent Key
may not function properly.
The Remote Engine Start function can only
be used when the Intelligent Key is within the
specified operating range from the vehicle.
The Remote Engine Start operating range is
approximately 197 ft (60 m) from the vehicle.
REMOTE STARTING THE
VEHICLE
To use the Remote Engine Start feature to
start the engine perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Press the

ton for at least 2 seconds. The following events will occur when the en-
gine starts:
• The parking lights will turn on and remain
on as long as the engine is running.
• The doors will be locked and the climate control system may come on.
• The engine will continue to run for 10 min- utes. Repeat the steps to extend the time
for an additional 10 minutes. For additional

OPERATING THE POWER
LIFTGATE
WARNING
• Make sure that all passengers have their
hands, etc., inside the vehicle before
closing the liftgate. •
To help avoid risk of injury or death
through unintended operation of the ve-
hicle and/or its systems, including en-
trapment in windows or inadvertent
door lock activation, do not leave chil-
dren, people who require the assistance
of others or pets unattended in your ve-
hicle. Additionally, the temperature in-
side a closed vehicle on a warm day can
quickly become high enough to cause a
significant risk of injury or death to
people or pets.
NOTE:
To open, close or reverse the power liftgate,
engage the P (Park) position. Also, the
power liftgate will not operate if the battery
voltage is low.
Power Open:
The power liftgate automatically moves from
the fully closed position to the fully open
position in approximately 5 to 8 seconds. The
power open feature can be activated by the
switch on the Intelligent Key, the instrument
panel switch or the liftgate opener switch
OA.
A chime sounds to indicate the power open
sequence has been started.

3-22Pre-driving checks and adjustments

A pinch strip is mounted on each side of the
liftgate. If an obstacle is detected by a pinch
strip during power close, the liftgate will re-
verse direction and return to the full open
position.
NOTE:
If the pinch strip is damaged or removed, the
power close function will not operate.
WARNING
There are some small distances immedi-
ately before the closed position which can-
not be detected. Make sure that all passen-
gers have their hands, etc., inside the
vehicle before closing the liftgate. Manual Mode:
If power operation is not available, the lift-
gate may be operated manually. Power op-
eration may not be available if multiple ob-
stacles have been detected in a single power
cycle or if the battery voltage is low.
If the power liftgate opener switch
OAis
pushed during power open or close, the
power operation will be canceled and the
liftgate can be operated manually.
To open the liftgate manually, unlock the
doors, push the liftgate opener switch
OAand
lift the liftgate.
To close, lower and push the liftgate down
securely.
MOTION-ACTIVATED LIFTGATE
(if so equipped)
The liftgate can be operated using a quick
kicking motion under the center of the rear
bumper.
To operate, the Intelligent Key must be within
31.5 in (80 cm) of the liftgate.
NOTE:
Tow hitches are available as an accessory for
this vehicle. If a tow hitch is installed, the
liftgate electronic control unit (ECU) needs
to be replaced with an ECU programmed
with towing logic for the Motion-Activated
Liftgate to function properly.

Linking log-in function to a stored
memory position
The log-in function can be linked to a stored
memory position with the following
procedure.
1. Place the ignition switch in the ON posi-tion while carrying the Intelligent Key that
was registered to the vehicle with a log-in
function.
NOTE:Make sure the Intelligent Keys are far apart.
Otherwise, the vehicle may detect the
wrong Intelligent Key.
2. Adjust the position of the driver’s seat, steering column and outside mirrors. For
additional information, see “Seats”
(P. 1-2), “Steering wheel” (P. 3-31) and
“Outside mirrors” (P. 3-34).
3. Place the ignition switch in the OFF position.
The next time you log in (selecting the user on
the display) after placing the ignition switch in
the ON position while carrying the Intelligent
Key, the system will automatically adjust to
the memorized driving position. For additional information, refer to the sepa-
rate INFINITI InTouch™ Owner’s Manual and
“Log-in function” in this section.
ENTRY/EXIT FUNCTION
This system is designed so that the driver's
seat and steering column will automatically
move when you the vehicle is engaged in the
P (Park) position. This allows the driver to
easily get in and out of the driver’s seat.
The driver’s seat will slide backward and the
steering column will move up when the igni-
tion is switched to OFF and the driver’s door
is opened.
The driver’s seat and steering wheel will re-
turn to the previous position when the igni-
tion is switched to ON.
The entry/exit function can be adjusted or
canceled through the “Comfort & Conve-
nience” options of the “Settings” menu in the
lower touch-screen display by performing the
following:
• Switch the Lift Steering upon Exit from ON
to OFF.
• Switch the Slide Driver Seat Back on Exit from ON to OFF.
For additional information, refer to the sepa-
rate INFINITI InTouch™ Owner’s Manual.
Restarting the entry/exit function
If the battery cable is disconnected, or if the
fuse opens, the stored memory positions will
be lost and some of the functions will be
restricted:
1. Drive the vehicle over 25 mph (40 km/h).
OR
2. Open and close the driver's door more than two times with the ignition switch in
the OFF position.
The entry/exit function should now work
properly.
SETTING MEMORY FUNCTION

linked to the Intelligent Key and the memo-
rized settings can be available for each Intel-
ligent Key.
• Climate control system
• Navigation system
• Audio system
To use the memory function, set the climate,
navigation and audio systems to the driver's
preferred settings. Lock the doors with the
Intelligent Key. Each Intelligent Key may be
