2020 INFINITI QX50 check engine light

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
steering wheel in a turn, the AFS system will
be activated.
The AFS will operate:∙ when the headlight switch is ON.
∙ when the shift lever 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 head-
light. 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 ve-
hicle 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 OFF position. When you turn
the headlight switch to the
position forfull illumination, the LED lights switch from
LED DRL system to the park function.
If the parking brake is applied before the
engine is started, the LED DRL system does
not illuminate. The LED DRL system illumi-
nates when the parking brake is released. The
LED DRL system will remain on until the
ignition switch is placed in the OFF position.
It is necessary at dusk to turn the headlight
switch on for interior controls and switches
to illuminate, as those remain off while the
switch is in the OFF position.
WARNING
When the LED DRL system is active, tail
lights on your vehicle are not on. It is neces-
sary at dusk to turn on your headlights.
Failure to do so could cause an accident in-
juring yourself and others.

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 climatecontrol 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, cushion,
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.
∙ When cleaning the seat, never use gaso- 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 posi- tion.
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 pushing the switch again. The climate
controlled seat blower remains on low
speed for approximately 60 seconds af-
ter pushing 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.

3-22Pre-driving checks and adjustments

1. Pull the hood lock release handle1lo-
cated below the driver side instrument
panel. The hood will spring up slightly.
2. Push the lever
2at the front of the
hood to the side with your fingertips and
raise the hood.
When closing the hood, lower it slowly and
make sure it locks into place.
WARNING
∙ Make sure the hood is completely closed and latched before driving. Failure to do
so could cause the hood to fly open and
result in an accident.
∙ If you see steam or smoke coming from the engine compartment, to avoid injury
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.

INFINITI VEHICLE IMMOBILIZER
SYSTEM
The INFINITI Vehicle Immobilizer System will
not allow the engine to start without the use
of the registered key.
If the engine fails to start using the registered
key, it may be due to interference caused by
another registered key, an automated toll
road device or automated 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
5 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
key.
If the no start condition re-occurs, INFINITI
recommends placing the registered key on a
separate key ring to avoid interference from
other devices. ∙ Make sure the area around the vehicle is
clear.
∙ Check fluid levels such as engine oil, cool- ant, brake fluid, and windshield-washer
fluid as frequently as possible, or at least
whenever you refuel.
∙ Check that all windows and lights are clean.
∙ Visually inspect tires for their appearance and condition. Also check tires for proper
inflation.
∙ Check that all doors are closed.
∙ Position seat and adjust head restraints/headrests.
∙ Adjust inside and outside mirrors.
∙ Fasten seat belts and ask all passengers to do likewise.
∙ Check the operation of warning lights when the ignition switch is placed in the
ON position. For additional information,
refer to “Warning lights, indicator lights
and audible reminders” in the “Instru-
ments and controls” section of this
manual. 1. Apply the parking brake.
2. Press the Park button to place the ve-
hicle in P (Park) or move the shift lever to
N (Neutral). P (Park) is recommended.
The starter is designed not to operate if
the shift lever is in any of the driving
positions.
3. Push the ignition switch to the ON posi- tion. Depress the brake pedal and push
the ignition switch to start the engine.
To start the engine immediately, push
and release the ignition switch while de-
pressing the brake pedal with the ignition
switch in any position.
