2023 INFINITI QX55 check engine

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 soequipped). (The system can be armed even
if the windows and moonroof are open.)
2. Remove the Intelligent Key from the vehicle.
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. 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.
2-34Instruments and controls

If the ambient image sensor is damaged due
to an accident, it is recommended that you
visit an INFINITI retailer.
Battery saver system
The battery saver system automatically turns
off the ignition after a period of time when
the ignition switch is left in the AUTO ACC or
ON position.
The battery saver system automatically turns
off the following lights after a period of time
when the ignition switch is placed in the OFF
position and the doors are closed:
• Headlights, when the headlight switch is inthe
orposition
• Interior lights, when left in the ON position
CAUTION
Even though the battery saver feature au-
tomatically turns off the headlights after a
period of time, you should turn the head-
light switch to the OFF position when the
engine is not running to avoid discharging
the vehicle battery.
Adaptive Front lighting System
(AFS) (if so equipped)
The Adaptive Front lighting System (AFS) will
automatically adjust the headlights (low
beam) toward the turning direction to im-
prove the driver’s view. When the headlight
switch is on and the driver operates the steer-
ing wheel in a turn, the AFS system will be
activated.
The AFS will operate:
• when the headlight switch is on.
• when the shift position is in any position other than P (Park) or R (Reverse).
• when the vehicle is driven at above 16 mph (25 km/h) for the left-side headlight. Note
that the right-side low beam headlight will
swivel but the left side will not swivel when
the vehicle is at a stop and the steering
wheel is turned. The vehicle must attain a
speed above 16 mph (25 km/h) before AFS
activates the left-side headlight.
AFS will also adjust the headlight to a proper
axis automatically, depending on the number
of occupants in the vehicle, the load the ve-
hicle is carrying and the road conditions.
If the AFS OFF indicator blinks or the vehicle
information display shows an AFS system
error message after the ignition switch has been pushed to the ON position, this may
indicate that the AFS is not functioning prop-
erly. Have the system checked. It is recom-
mended you visit an INFINITI retailer for this
service. When the engine is started, the head-
lights will vibrate to check the system condi-
tion. This is not a malfunction.
Automatic headlight aiming control
(if so equipped)
Your vehicle is equipped with an automatic
headlight levelling system. The headlight axis
is controlled automatically.
INFINITI recommends that you consult the
local regulations on the use of lights.
LED DAYTIME RUNNING LIGHTS
(DRL) SYSTEM
The LED portion of the headlights automati-
cally illuminate at 100% intensity when the
engine is started and the parking brake re-
leased. The LED Daytime Running Lights
(DRL) system operates with the headlight
switch in the AUTO or OFF position. When
you turn the headlight switch to the
position for full illumination, the LED lights
switch from LED DRL system to the park
function.

WARNING
Do not use or allow occupants to use the
climate controlled seats if you or the occu-
pants cannot monitor seat temperatures
or have an inability to feel pain in those
body parts in contact with the seat. Use of
the climate controlled seats by such people
could result in serious injury.
CAUTION
• The battery could run down if the climate
control seat is operated while the engine
is not running.
• Do not use the climate control seat for
extended periods or when no one is using
the seat.
• Do not put anything on the seat which
insulates heat, such as a blanket, cush-
ion, seat cover, etc. Otherwise, the seat
may become overheated.
• Do not place anything hard or heavy on
the seat or pierce it with a pin or similar
objects. This may result in damage to the
climate controlled seat.
• Any liquid spilled on the seat should be
removed immediately with a dry cloth.

line, benzine, thinner, or any similar
materials.
• If any malfunctions are found or the cli-
mate controlled seat does not operate,
turn the switch off and have the system
checked. It is recommended that you
visit an INFINITI retailer for this service. The climate controlled seat cools down the
front seat by blowing cool air from under the
surface of the seat. The climate control
switch is located on the center console.
The climate controlled seat can be operated
as follows:
1. Place the ignition switch in the ON
position.
2. Push the climate controlled seat switches to cool the seat. The indicator light on the
corresponding switch will illuminate.
3. Adjust the desired amount of air by push- ing the switch again. The climate con-
trolled seat blower remains on low speed
for approximately 60 seconds after push-
ing the switch on.
4. When the vehicle's interior is warmed or cooled, or before you leave the vehicle, be
sure to turn off the climate controlled
seats. To turn off the climate controlled
seats, push the switch until the indicator
light does not illuminate.
