2023 INFINITI QX50 key battery

Laws in some local communities may restrict
or prohibit the use of Remote Engine Start, or
the amount of time a parked vehicle engine
may idle. For example, some laws require a
person using Remote Engine Start to have
the vehicle in view or may restrict idling time
except in freezing temperatures. Check local
regulations for any requirements.
Other conditions may affect the function of
the Remote Engine Start feature. For addi-
tional information, see “Conditions the Re-
mote Engine Start will not work” (P. 3-20).
Other conditions can affect the performance
of the Intelligent Key transmitter. For addi-
tional information, see “INFINITI Intelligent
Key” (P. 3-2).
REMOTE ENGINE START
OPERATING RANGE
WARNING
• 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 vehicle. Additionally, 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.
• Do not use Remote Engine Start in closed
spaces such as a garage. Do not breathe
exhaust gases; they contain colorless
and odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause un-
consciousness or death.
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 per-
form the following:
1. Aim the Intelligent Key at the vehicle.
2. Press the
button to lock all doors.
3. Within 5 seconds press and hold the
button until the turn signal lights flash and
the tail lamps turn on. If the vehicle is not
within view press and hold the
but-
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
information, see “Extending engine run
time” (P. 3-20).
Press and hold the brake pedal while switch-
ing the ignition to the ON position before
driving. For additional information, see “Driv-
ing the vehicle” (P. 5-18).
Pre-driving checks and adjustments3-19

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. • When the vehicle is locked, the liftgate can
be opened by the instrument panel switch,
Intelligent Key and liftgate opener switch
OA(with the Intelligent Key in liftgate op-
eration range). The liftgate will individually
unlock and open. Once the liftgate is
closed, the vehicle will remain unlocked. To
lock the liftgate, push the liftgate request
switch
OB(with the Intelligent Key in lift-
gate operation range) or press the
button on the Intelligent Key.
• To open the liftgate with the Intelligent Key, hold the button for 1 second.
• To open the liftgate with the instrument panel switch, hold the button for 1 second.
• To open the liftgate with the liftgate opener switch
OA, the liftgate must be un-
locked if the Intelligent Key is not in liftgate
operation range. Power Close:
The power liftgate automatically moves from
the fully open position to the secondary po-
sition. When the liftgate reaches the second-
ary position, the cinching motor engages and
pulls the liftgate to its primary latch position.
Power close takes approximately 7 to 10
seconds. The power close feature can be ac-
tivated by the switch on the Intelligent Key,
the instrument panel, the liftgate close switch
OCand the liftgate lock switchOD. A chime
sounds to indicate the power close sequence
has been started.

• If the liftgate opener switchOAis activated
while the cinching motor is engaged, the
cinching motor will disengage and release
the latch and the liftgate will open.
• The Intelligent Key button must be held for 1 second before the liftgate closes.
• The liftgate close switch
OCcan only be
used to close the liftgate if the power lift-
gate main switch is in the ON position.
• If the liftgate lock switch
ODis activated the
liftgate will begin to close and all doors will
lock.
Stop - Reverse:
During the open/close movement, the lift-
gate can be stopped if the Intelligent Key,
instrument panel or liftgate opener switch
OA, liftgate close switchOCor liftgate lock
switch
ODis pushed. The liftgate can be re-
versed if the Intelligent Key, instrument panel
or liftgate opener switch
OA, liftgate request
switch
OBor liftgate lock switchODis pushed
again.
Auto Reverse:
If an obstacle is detected during power open
or power close, a warning chime will sound
and the liftgate will reverse direction and re-
turn to the full open or full close position. If a second obstacle is detected, the liftgate
motion will stop and the liftgate will enter
manual mode.
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

or if the liftgate unexpectedly closes at
any time while a continuous warning
chime sounds, do not operate the lift-
gate. There may be a pressure loss in one
or both of the liftgate struts. It is recom-
mended that you have the liftgate in-
spected. It is recommended that you visit
an INFINITI retailer for this service.
• Do not activate the power liftgate if one
or both of the liftgate struts are re-
moved. Damage to the liftgate or power
liftgate mechanisms may occur.
• Keep the power liftgate main switch (if
so equipped) in the OFF position when
washing or working around the back of
the vehicle (with Intelligent Key) to pre-
vent inadvertent opening/closing.
Power liftgate release
