2020 INFINITI QX50 check engine light

High Beam Assist indicatorlight (green)
This indicator light illuminates when the
headlights come on while the headlight
switch is in the AUTO position with the high
beams selected. This indicates that the high
beam assist is operational.
For additional information, refer to “Head-
light switch” in this section.
High beam indicator light(blue)
This blue light comes on when the headlight
high beams are on and goes out when the
low beams are selected.
The high beam indicator light also comes on
when the passing signal is activated.
Malfunction Indicator Light(MIL)
If this indicator light comes on steady or
blinks while the engine is running, it may indi-
cate a potential emission control malfunc-
tion. The MIL may also come on steady if the
fuel-filler cap is loose or missing, or if the
vehicle runs out of fuel. Check to make sure
the fuel-filler cap is installed and closed
tightly, and that the vehicle has at least 3 gal-
lons (11.4 liters) of fuel in the fuel tank.
After a few driving trips, the
light
should turn off if no other potential emission
control system malfunction exists.
If this indicator light comes on steady for
20 seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an emission
control system inspection/maintenance test.
For additional information, refer to “Readi-
ness for Inspection/Maintenance (I/M) test”
in the “Technical and consumer information”
section of this manual. Operation
The MIL will come on in one of two ways:
∙ MIL on steady — An emission control sys- tem malfunction has been detected.
Check the fuel-filler cap if the Loose Fuel
Cap warning appears in the vehicle infor-
mation display. If the fuel-filler cap is
loose or missing, tighten or install the cap
and continue to drive the vehicle.
The
light should turn off after a
few driving trips. If the
light does
not turn off after a few driving trips, have
the vehicle inspected. It is recommended
that you visit an INFINITI retailer for this
service. You do not need to have your
vehicle towed to the retailer.
∙ MIL blinking — An engine misfire has been detected which may damage the emis-
sion control system. To reduce or avoid
emission control system damage:
– do not drive at speeds above 45 mph (72 km/h).
– avoid hard acceleration or decelera- tion.
– avoid steep uphill grades.
– if possible, reduce the amount of cargo being hauled or towed.
Instruments and controls2-17

The MIL may stop blinking and come on
steady. Have the vehicle inspected. It is rec-
ommended that you visit an INFINITI retailer
for this service. You do not need to have your
vehicle towed to the retailer.
CAUTION
Continued vehicle operation without hav-
ing the emission control system checked
and repaired as necessary could lead to
poor driveability, reduced fuel economy,
and possible damage to the emission con-
trol system.
Security indicator light
This light blinks when the ignition switch is
placed in the OFF or LOCK position.
The blinking security indicator light indicates
that the security systems equipped on the
vehicle are operational.
For additional information, refer to “Security

Side light and headlightindicator light (green)
The side light and headlight indicator light
illuminates when the side light or headlights
are on (not including daytime running or sig- nature lights). If the headlight switch is in the
AUTO position, the side light and headlight
indicator light will illuminate when the head-
lights turn on. For additional information, re-
fer to “Headlight switch” in this section.
Slip indicator light
This indicator light will blink when the VDC
system is operating, thus alerting the driver to
the fact that the road surface is slippery and
the vehicle is nearing its traction limits.
You may feel or hear the system working; this
is normal.
The light will blink for a few seconds after the
VDC system stops limiting wheel spin.
The
indicator light also comes on when
you place the ignition switch in the ON posi-
tion. The light will turn off after a period of
time if the system is operational. If the light
does not come on have the system checked. It
is recommended that you visit an INFINITI
retailer for this service.
Turn signal/hazard indicator
lights
The appropriate light flashes when the turn
signal switch is activated. Both lights flash when the hazard switch is
turned on.
Vehicle Dynamic Control
(VDC) OFF indicator light
This indicator light comes on when the VDC is
turned off in the lower display. This indicates
the VDC has been turned off.
Turn the VDC on again by reactivating it in
the lower display, or restarting the engine.
The system will be reactivated. For additional
information, refer to “Vehicle Dynamic Con-
trol (VDC) system” in the “Starting and driv-
ing” section of this manual.
The VDC light also comes on when the igni-
tion switch is placed in the ON position. The
light will turn off after a period of time if the
system is operational. If the light stays on or
comes on along with the
indicator light
while you are driving, have the VDC system
checked. It is recommended that you visit an
INFINITI retailer for this service.
