stop start INFINITI Q50 2020 Owner's Manual

Troubleshooting:
If you think the front passenger air bag
status light is incorrect:
1. If the light is ON with an adult occupyingthe front passenger seat:
.Occupant is a small adult - the air bag
status light is functioning as intended.
The front passenger air bag is sup-
pressed.
However, if the occupant is not a small
adult, then this may be due to the
following conditions that may be inter-
fering with the weight sensors:
.Occupant is not sitting upright, lean- ing against the seatback, and cen-
tered on the seat cushion with his/her
feet comfortably extended to the
floor.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling onthe back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the front
passenger seat.
.An object placed between the seat cushion and center console or be-
tween the seat cushion and the door. If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still ON after this, the
person should be advised not to ride in
the front passenger seat and the vehicle
should be checked as soon as possible. It
is recommended you visit an INFINITI
retailer for this service.
2. If the light is OFF with a small adult, child or child restraint occupying the front
passenger seat:
This may be due to the following condi-
tions that may be interfering with the
weight sensors:
.Small adult or child is not sittingupright, leaning against the seatback,
and centered on the seat cushion with
his/her feet comfortably extended to
the floor.
.The child restraint is not properly
installed as outlined in “Child re-
straints” (P.1-21).
.An object weighing over 9.1 lbs (4 kg) hanging on the seat or placed in the seatback pocket.
.A child restraint or other object press-
ing against the rear of the seatback.
.A rear passenger pushing or pulling on
the back of the front passenger seat.
.Forcing the front seat or seatbackagainst an object on the seat or floor
behind it.
.An object placed under the frontpassenger seat.
.An object placed between the seat
cushion and center console.
.The front passenger seat head re-straint contacting the roof.
If the vehicle is moving, please come to a
stop when it is safe to do so. Check and
correct any of the above conditions.
Restart the vehicle and wait 1 minute.
NOTE: A system check will be performed during
which the front passenger air bag status
light will remain lit for about 7 seconds
initially.
If the light is still OFF after this, the small
adult, child or child restraint should be
repositioned in the rear seat and the
vehicle should be checked by an INFINITI
retailer as soon as possible.

indicator:
When the parking brake is released and the
brake fluid level is sufficient, if both the
brake warning light and the Anti-lock Brak-
ing System (ABS) warning light illuminate, it
may indicate the ABS is not functioning
properly. Have the brake system checked,
and if necessary repaired. It is recommended
you visit an INFINITI retailer for this service.
(See “Anti-lock Braking System (ABS) warn-
ing light” (P.2-10).)
WARNING
.
Your brake system may not be work-

Pre-driving checks and adjustments3-21

THREE-WAY CATALYST
The three-way catalyst is an emission con-
trol device installed in the exhaust system.
Exhaust gases in the three-way catalyst are
burned at high temperatures to help reduce
pollutants.
WARNING
.The exhaust gas and the exhaust
system are very hot. Keep people,
animals or flammable materials away
from the exhaust system compo-
nents.
. Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They
may ignite and cause a fire.
CAUTION
.Do not use leaded gasoline. Deposits
from leaded gasoline seriously reduce
the three-way catalyst’s ability to
help reduce exhaust pollutants.
. Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly. It is recommended
you visit an INFINITI retailer for this
service.
. Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damaging
the three-way catalyst.
. Do not race the engine while warming
it up.
. Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.) As an added safety feature, your vehicle has
been equipped with a Tire Pressure Mon-
itoring System (TPMS) that illuminates a low
tire pressure telltale when one or more of
your tires is significantly under-inflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and
check your tires as soon as possible, and
inflate them to the proper pressure. Driving
on a significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
For models with run-flat tires, if the vehicle
is being driven with one or more flat tires,
the low tire pressure warning light will
illuminate continuously and a chime will
sound for 10 seconds. The flat tire warning
will also appear in the vehicle information
display. The chime will only sound at the first
indication of a flat tire, and the warning light
will illuminate continuously. When the flat
tire warning is activated, it is recommended
you have the system reset and the tire
checked and replaced if necessary by an
INFINITI retailer. Even if the tire is inflated
to the specified COLD tire pressure, the
warning light will continue to illuminate until
the system is reset by an INFINITI retailer.
Your vehicle can be driven for a limited time
on a flat tire. See “Run-flat tires” (P.8-32).
