alarm INFINITI QX50 2021 Owner's Manual

Vehicle ahead detection
indicator
This indicator shows when the following sys-
tems (if so equipped) are engaged and have
detected a vehicle:
• Distance Control Assist (DCA)
• Forward Emergency Braking (FEB) withPedestrian Detection
• Predictive Forward Collision Warning (PFCW)
For additional information, see “Distance
Control Assist (DCA)” (P. 5-106), “Forward
Emergency Braking (FEB) with Pedestrian
Detection” (P. 5-123) or “Predictive Forward
Collision Warning (PFCW)” (P. 5-133) Your vehicle has two types of security
systems:
• Vehicle security system
• INFINITI Vehicle Immobilizer System
VEHICLE SECURITY SYSTEM
The vehicle security system provides visual
and audible alarm signals if someone opens
the doors, liftgate or hood when the system is
armed. It is not, however, a motion detection
type system that activates when a vehicle is
moved or when a vibration occurs.The system helps deter vehicle theft but can-
not prevent it nor can it prevent the theft of
interior or exterior vehicle components in all
situations. Always secure your vehicle even if
parking for a brief period. Never leave your
Intelligent Key in the vehicle, and always lock
the vehicle when unattended. Be aware of
your surroundings, and park in secure, well-lit
areas whenever possible.
Many devices offering additional protection,
such as component locks, identification
markers, and tracking systems, are available
at auto supply stores and specialty shops. An
INFINITI retailer may also offer such equip-
ment. Check with your insurance company to
see if you may be eligible for discounts for
various theft protection features.
How to arm the vehicle security
system
1. Close all windows and the moonroof (if so
equipped). (The system can be armed even
if the windows and moonroof are open.)
2. Remove the Intelligent Key from the vehicle.

SECURITY SYSTEMS
Instruments and controls2-29

3. Close all doors, hood and liftgate. Lock alldoors. The doors can be locked with the
Intelligent Key, door handle request
switch, or power door lock switch.
4. Confirm that the
security indicator
light stays on for about 30 seconds. The
vehicle security system is now pre-armed.
The vehicle security system will automati-
cally shift into the armed phase. The
security light begins to flash once every
three seconds. If during the pre-armed
phase one of the following occurs, the
system will not arm:
• Any door is unlocked with the Intelligent Key or door request switch.
• Ignition switch is placed in AUTO ACC or ON position.
• Even when the driver and/or passengers
are in the vehicle, the system will activate
with all the doors, hood and liftgate locked
with the ignition switch placed in the
LOCK position. When placing the ignition
switch in the AUTO ACC or ON position,
the system will be released.
Vehicle security system activation
The vehicle security system will give the fol-
lowing alarm:
• The turn signals blink and the horn sounds intermittently.
• The alarm automatically turns off after a period of time. However, the alarm reacti-
vates if the vehicle is tampered with again.
The alarm can be shut off by pressing the
button on the Intelligent Key.
The alarm is activated by:
• Opening the door or liftgate without using the Intelligent Key (even if the door is un-
locked by releasing the door inside lock
switch).
How to stop an activated alarm
The alarm stops only by unlocking the driver’s
door or the liftgate by pressing the
button on the Intelligent Key or pushing the
request switch on the driver's or passenger's
door with the Intelligent Key in range of the
door handle.
INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of a registered INFINITI Vehicle Immobilizer
System key.
If the engine fails to start using a registered
INFINITI Vehicle Immobilizer System key (for
example, when interference is caused by an-
other INFINITI Vehicle Immobilizer System
key, an automated toll road device or auto-
matic payment device on the key ring), restart
the engine using the following procedures:
1. Leave the ignition switch in the ON posi- tion for approximately 5 seconds.
2. Place the ignition switch in the OFF or LOCK position, and wait approximately
10 seconds.
3. Repeat steps 1 and 2.
4. Restart the engine while holding the de- vice (which may have caused the interfer-
ence) separate from the registered
INFINITI Vehicle Immobilizer System key.
If the no start condition re-occurs, INFINITI
recommends placing the registered INFINITI

3-20Pre-driving checks and adjustments

•The system will not detect small objects
below the bumper, and may not detect
objects close to the bumper or on the
ground.
• The system may not detect the following
objects:
– Fluffy objects such as snow, cloth,
cotton, grass or wool.
– Thin objects such as rope, wire or
chain.
– Wedge-shaped objects.
• If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
jects or false alarms.
CAUTION
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
System temporarily unavailable
When the amber markers are displayed at the
corners of the vehicle icon and the function
cannot be activated from the Camera setting
menu (the setting items are grayed out), the
sonar system may be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (lo-
cated on the front and rear bumper fascia)
free from accumulations of snow, ice and
dirt. Do not scratch the surface of the sonar
sensors when cleaning. If the sensors are
covered, the accuracy of the sonar function
will be diminished.
Monitor, climate, audio, phone and voice recognition systems4-27

The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
• The sonar system is not a replacement
for proper driving procedures and is not
designed to prevent contact with ve-
hicles or objects. •
The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
• This function is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bumper
fascia, leaving it misaligned or bent, the sensing
zone may be altered causing inaccurate mea-
surement of obstacles or false alarm.
CAUTION
•
Excessive noise (such as audio system vol-
ume or an open vehicle window) will inter-
fere with the tone and it may not be heard.
• Keep the sonar sensors (located on the
bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the
sensors are covered, the accuracy of the
sonar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever
is in the D (Drive) position and both front and
rear obstacles when the shift lever is in the R
(Reverse) position.
