battery INFINITI QX50 2021 Owner's Guide

•Do not strike the Intelligent Key sharply
against another object.
• Do not change or modify the Intelligent
Key.
• Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet, im-
mediately wipe until it is completely dry.
• Do not place the Intelligent Key for an
extended period in an area where tem-
peratures exceed 140°F (60°C).
• Do not attach the Intelligent Key with a
key holder that contains a magnet.
• Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment and
personal computers.
If an Intelligent Key is lost or stolen, INFINITI
recommends erasing the ID code of that In-
telligent Key from the vehicle. This may pre-
vent the unauthorized use of the Intelligent
Key to operate the vehicle. For information
regarding the erasing procedure, it is recom-
mended that you visit an INFINITI retailer.
OPERATING RANGE
The Intelligent Key functions can only be used
when the Intelligent Key is within the speci-
fied operating range from the door handle
request switch or the one touch unlock sen-
sor
O1. When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key operating range becomes narrower, and
the Intelligent Key may not function properly.
The operating range is within 31.5 in (80 cm)
from each request switch or one touch unlock
sensor
O1.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the request
switches or the one touch unlock sensor may
not function.
If any of the front doors are recently closed
and locked, you must wait 2 seconds before
you can unlock the door with the one touch
unlock sensor. Pulling the handle within 2
seconds of locking the door will allow you
time to confirm that the door has been locked
without accidentally unlocking the door with
the one touch unlock sensor.
If you pull the door handle with your gloved
hand, the one touch unlock sensor operation
may not function.
When the Intelligent Key is within the operat-
ing range, it is possible for anyone, even
someone who does not carry the Intelligent
Key, to push the request switch or the one
touch unlock sensor to lock/unlock the door
within range.

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.

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.

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.

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.

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.
