fuel INFINITI QX80 2021 User Guide

WARNING
.If the light does not illuminate with
the ignition switch pushed ON, have
the vehicle checked as soon as possi-
ble. It is recommended you visit an
INFINITI retailer for this service.
. 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 permanently 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
personal injury. Check the tire pres-
sure for all four tires. Adjust the tire
pressure to the recommended COLD
tire pressure shown on the Tire and
Loading Information label to turn the
low tire pressure warning light OFF.
If the light still illuminates while
driving after adjusting the tire pres-
sure, a tire may be flat or the TPMS
may be malfunctioning. If you have a
flat tire, replace it with a spare tire as
soon as possible. If no tire is flat and
all tires are properly inflated, it is recommended you consult an
INFINITI retailer.
. Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, 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 you visit an INFINITI
retailer for these services.
. Replacing tires with those not origin-
ally specified by INFINITI could affect
the proper operation of the TPMS.
CAUTION
.The TPMS is not a substitute for the
regular 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.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is running,
it may indicate a potential emission control
malfunction.
The malfunction indicator light 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 US gallons (14 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 remains on 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.
(See “Readiness for Inspection/Mainte-
nance (I/M) test” (P.10-34).)
Operation:
The malfunction indicator light will come on
in one of two ways:
. Malfunction indicator light on steady —
An emission control system malfunction
has been detected. Check the fuel-filler
Instruments and controls2-17

2-18Instruments and controls
cap if the Loose Fuel Cap warning
appears in the vehicle information dis-
play. 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 thelight does not turn off
after a few driving trips, have the vehicle
inspected. It is recommended you visit an
INFINITI retailer for this service. You do
not need to have your vehicle towed to
the retailer.
. Malfunction indicator light blinking — An
engine misfire has been detected which
may damage the emission control sys-
tem.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45 MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.
4) If possible, reduce the amount of cargo being hauled or towed.
The malfunction indicator light may stop
blinking and remain on.
Have the vehicle inspected. It is recom-
mended 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
having the emission control system
checked and repaired as necessary could
lead to poor driveability, reduced fuel
economy, and possible damage to the
emission control system.
Master warning light
When the ignition switch is in the ON
position, the master warning light illumi-
nates when a warning message appears in

(VDC) off indicator light
When the ignition switch is in the ON
position, the Vehicle Dynamic Control

system is not operating.
When the 4L position is selected with the Four-Wheel Drive (4WD) shift switch, the
VDC system is disabled and the VDC off
indicator light illuminates. (4WD models)
For additional information, see “Vehicle
Dynamic Control (VDC) system” (P.5-125).
Vehicle Dynamic Control
(VDC) warning light
The light will blink when the VDC system or
the traction control system is operating, thus
alerting the driver that the vehicle is nearing
its traction limits. The road surface may be
slippery.
When the VDC warning light illuminates
when the VDC system is turned on, this light
alerts the driver to the fact that the VDC
system’s fail-safe mode is operating, for
example the VDC or hill start assist system
may not be functioning properly. Have the
system checked. It is recommended you visit
an INFINITI retailer for this service. If a
malfunction occurs in the system, the VDC
system function will be canceled but the
vehicle is still driveable. For additional
information, see “Vehicle Dynamic Control
(VDC) system” (P.5-125).
