2019 INFINITI QX50 hood open

∙ If the light illuminates while driving,avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed, pull
off the road to a safe location and stop
the vehicle as soon as possible. Driving
with under-inflated tires may perma-
nently damage the tires and increase the
likelihood of tire failure. Serious vehicle
damage could occur and may lead to an
accident and could result in serious per-
sonal injury or death. Check the tire pres-
sure for all four tires. Adjust the tire pres-
sure to the recommended COLD tire
pressure show on the Tire and Loading
Information label located in the driver’s
door opening to turn the low tire pressure
warning light OFF. If the light still illumi-
nates while driving after adjusting the
tire pressure, a tire may be flat or the
TPMS may be malfunctioning. If you
have a flat tire, replace it with a replace-
ment tire as soon as possible. If no tire is
flat and all tires are properly inflated,
have the vehicle checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pressure
warning light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
CAUTION
∙ The TPMS is not a substitute for theregular tire pressure check. Be sure to
check the tire pressure regularly.
∙ If the vehicle is being driven at speeds of less than 16 mph (25 km/h), the TPMS
may not operate correctly.
∙ Be sure to install the specified size of tires to the four wheels correctly.

Your vehicle has two types of security sys-
tems:∙ 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.
The system can be armed even if the
windows and moonroof are open.
2. Remove the Intelligent Key from the ve- hicle.
3. Close all doors, hood and liftgate. Lock all doors. The doors can be locked with
the Intelligent Key, door handle request
switch or power door lock switch. Key fob operation:
4. Confirm that the
indicator light
comes on. The
indicator stays illu-
minated for a period of time indicating
that the system is in the pre-armed
phase.
The
indicator light will blink every
3 seconds once the security system is
armed.
If during the pre-armed phase one of the
following occurs, the system will not
arm:
∙ Any door is unlocked with the me- chanical key
∙ A door is opened with the release but- ton with the Intelligent Key on your
person
∙ The doors are unlocked using the un- lock button on the Intelligent Key
∙ The ignition switch is placed in the ON position

SECURITY SYSTEMS
2-32Instruments and controls

∙Even when the driver and/or passengers
are in the vehicle, the system will acti-
vate when all the doors, hood and lift-
gate are locked with the ignition switch
placed in the LOCK position. When plac-
ing the ignition switch in the ON posi-
tion, 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 reac-
tivates if the vehicle is tampered with
again. The alarm can be shut off by un-
locking the driver’s door or liftgate with
the key or by pressing the
button
on the Intelligent Key.
The alarm is activated by:
∙ Opening the door or liftgate without us- ing the key or Intelligent Key (even if the
door is unlocked 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 with the key, 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 po- sition 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 inter-
ference) separate from the registered
INFINITI Vehicle Immobilizer System
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered INFINITI
Vehicle Immobilizer System key on a separate
key ring to avoid interference from other de-
vices.
FCC Notice:
For USA:
This device complies with part 15 of the FCC
Rules. Operation is subject to the following
two conditions: (1) This device may not
cause harmful interference, and (2) this de-
vice must accept any interference received,

do not open the hood.
WARNING
∙ Always be sure the liftgate has beenclosed securely to prevent it from open-
ing while driving.
∙ Do not drive with the liftgate open. This could allow dangerous exhaust gases to
be drawn into the vehicle. For additional
information, refer to “Exhaust gas (car-
bon monoxide)” in the “Starting and driv-
ing” section of this manual.
∙ 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 children,
people who require the assistance of oth-
ers 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 signifi-
cant risk of injury or death to people and
pets.
∙ Always be sure that hands and feet are clear of the door frame to avoid injury
while closing the liftgate.

4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least2-4hours, de-
pending on outside temperatures, to
properly warm the engine coolant. Use
an appropriate timer to turn the engine
block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away
from moving parts.
ACTIVE NOISE CANCELLATION
This system uses microphones1located in-
side the vehicle to detect engine booming
noise. The system then automatically gener-
ates a noise canceling sound through the
speakers and woofer (if so equipped) to re-
duce engine booming noise.
NOTE:
To operate the active noise cancellation sys-
tem properly:
∙ Do not cover the speakers or woofer (if
so equipped).
