2021 INFINITI Q50 Owner's Manual

driving a long distance at high speeds
may damage the tires.— Do not drive at speeds above 50 MPH (80 km/h) and do not drive
more than approximately 93 miles
(150 km) with a punctured run-
flat tire. The actual distance the
vehicle can be driven on a flat tire
depends on outside temperature,
vehicle load, road conditions and
other factors.
— If you detect any unusual sounds or vibrations while driving with a
punctured run-flat tire, pull off
the road to a safe location and
stop the vehicle as soon as possi-
ble. The tire may be seriously
damaged and need to be replaced.
. 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 the 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as pos-
sible. 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 (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 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 (US only)” (P.10-23).)
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
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 45MPH (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 the vehicle information display.
See “Vehicle information display” (P.2-18).
Power steering warning light
Models with Direct Adaptive Steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light stays on for a
few seconds and turns off. This indicates
that Direct Adaptive Steering is operational.
Drive the vehicle after the power steering
warning light turns off.
If the power steering warning light illumi-
nates while driving, pull off the road to a
safe location and stop the vehicle. If the
power steering warning light turns off, you
can drive again. If the power steering
warning light continues to illuminate, it is
recommended you have Direct Adaptive
Steering checked by an INFINITI retailer.
(See “Direct Adaptive Steering type” (P.5-
123).)
Models with electric power steering :
When the ignition switch is in the ON
position, the power steering warning light
illuminates. After starting the engine, the
power steering warning light turns off. This
indicates the electric power steering is
operational.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the electric power steering is not
functioning properly and may need servicing.
It is recommended you have the electric
power steering checked by an INFINITI
retailer.
When the power steering warning light
illuminates with the engine running, the
power assist to the steering will cease
operation but you will still have control of
the vehicle. At this time, greater steering
efforts are required to operate the steering
wheel, especially in sharp turns and at low
speeds.
See “Electric power steering type” (P.5-123).
