2021 INFINITI Q50 maintenance

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.

Ambient image sensor maintenance:
The ambient image sensor
for the high
beam assist system is located in front of the
inside mirror. To keep the proper operation
of the high beam assist system and prevent a
system malfunction, be sure to observe the
following:
. Always keep the windshield clean.
. Do not attach a sticker (including trans-
parent material) or install an accessory
near the ambient image sensor.
. Do not strike or damage the areas around
the ambient image sensor. Do not touch
the sensor lens that is located on the
ambient image sensor. If the ambient image sensor is damaged due
to an accident, it is recommended you
contact an INFINITI retailer.
Battery saver system
A chime will sound and the light reminder
warning will appear in the vehicle informa-
tion display when the driver side door is
opened with the light switch in the
orposition and the ignition switch in the
ACC, OFF or LOCK position.
When the headlight switch is in the
orposition while the ignition switch is in
the ON position, the lights will automatically
turn off after a period of time when the
ignition switch has been pushed to the OFF
position.
When the headlight switch remains in the
orposition after the lights auto-
matically turn off, the lights will turn on
when the ignition switch is pushed to the ON
position.
CAUTION
. When you turn on the headlight
switch again after the lights auto-
matically turn off, the lights will not
turn off automatically. Be sure to
turn the light switch to the OFF
position when you leave the vehicle for extended periods of time, other-
wise the battery will be discharged.
. Never leave the light switch on when
the engine is not running for a period
of time even if the headlights turn off
automatically.
Daytime running light system
The daytime running lights automatically
illuminate when the engine is started with
the parking brake released. The daytime
running lights operate with the headlight
switch in the OFF, AUTO or
position.
Turn the headlight switch to theposition
for full illumination when driving at night.
If the parking brake is applied before the
engine is started, the daytime running lights
do not illuminate. The daytime running lights
illuminate once the parking brake is released.
The daytime running lights will remain on
until the ignition switch is pushed to the OFF
position.
WARNING
When the daytime running light system
is active, tail lights on your vehicle are
not on. It is necessary at dusk to turn on
your headlights. Failure to do so could
cause an accident injuring yourself and

CAUTION
.Do not use alcohol, benzine or thinner
to clean the camera. This will cause
discoloration.
. Do not damage the camera as the
monitor screen may be adversely
affected.
If dirt, rain or snow accumulates on the
camera
, the RearView Monitor may not

When theicon is displayed on the
screen, the camera image may be receiving
temporary electronic disturbances from sur-
rounding devices. This will not hinder normal
driving operation but the system should be
inspected. It is recommended that you visit
an INFINITI retailer for this service.

SONAR SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the sonar function. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.Inclement weather or ultrasonic
sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system, including
reduced performance or a false acti-
vation.
. The system is not designed to pre-
vent contact with small or moving
objects.
. The system will not detect small
objects below the bumper, and may
not detect objects close to the bum-
per or on the ground.
. The system may not detect the
following objects:
— Fluffy objects such as snow, cloth, cotton, grass or wool.
— Thin objects such as rope, wire or chain. — Wedge-shaped objects.
. If your vehicle sustains damage to the
bumper fascia, leaving it misaligned
or bent, the sensing zone may be
altered causing inaccurate measure-
ment of objects or false alarms.
CAUTION
Excessive noise (such as audio system
volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
System temporarily unavailable
When the amber markers are displayed at
the corners of the vehicle icon and the
function cannot be activated from the
Parking sonar settings menu (the setting
items are grayed out), the sonar system may
be malfunctioning.
SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar (located on
the front and rear bumper fascia) free
from accumulations of snow, ice and dirt.
Do not scratch the surface of the sonar
when cleaning. If the sensors are cov-
ered, the accuracy of the sonar function
will be diminished.

— When there is dirt, water drops orsnow on the camera lens.
— When the position of the moving objects in the display is not chan-
ged.
. The MOD system might detect flow-
ing water droplets on the camera
lens, white smoke from the muffler,
moving shadows, etc.
. The MOD system may not function
properly depending on the speed,
direction, distance or shape of the
moving objects.
. If your vehicle sustains damage to the
parts where the camera is installed,
leaving it misaligned or bent, the
sensing zone may be altered and the
MOD system may not detect objects
properly.
. When the temperature is extremely
high or low, the screen may not
display objects clearly. This is not a
malfunction.
