2018 INFINITI QX30 ECU

child restraints and booster seats be properly
installed in a rear seat. If this is not possible,
the occupant classification sensor is designed
to operate as described above to turn the
front passenger air bag OFF for specified
child restraints as required by the regulations.
Failing to properly secure child restraints and
to use the ALR mode may allow the restraint
to tip or move in a collision or sudden stop.
This can also result in the passenger air bag
inflating in a crash instead of being OFF. For
additional information about proper use and
installation, refer to "Child restraints" in the "1.
Safety — seats, seat belts and supplemental
restraint system" section.
If the front passenger seat is not occupied,
the front passenger air bag is designed not to
inflate in a crash. However, heavy objects
placed on the seat could result in air bag
inflation, because of the object's weight de-
tected by the occupant classification sensor.
Other conditions could also result in air bag
inflation, such as if a child is standing on the
seat, or if two children are on the seat, con-
trary to the instructions in this manual. Al-
ways be sure that you and all vehicle occu-
pants are seated and restrained properly.If the automatic front passenger air bag de-
activation system detects that:
•The front passenger seat is unoccupied,
the indica-
tor light lights up after the system self-test
and remains lit. This indicates that the
front passenger front air bag is disabled.
•The front passenger seat is occupied by a
properly restrained child up to the approxi-
mate size and weight of a one year old, the
indicator
light lights up after the system self-test
and remains lit. This indicates that the
front passenger front air bag is disabled.
If neither the OFF> or the
indicator lights light up, or if either indica-
tor light only lights up intermittently during
the journey, the front passenger seat may
not be used for a child restraint. Use an-
other seating position for the child re-
straint. For further information see
"Troubleshooting" later in this section.
•The front passenger seat is occupied by a
properly restrained child who is larger than
the approximate size and weight of a one
year old, either the BAG ON> or
indicator light lights up and remains lit af-
ter the system self-test depending on the
result of the classification. The result of
the classification is dependent on, among
other factors, the child restraint system
and the child's build.
Move the front passenger seat as far back
as possible. See "Child restraints" earlier in
this section.
•The front passenger seat is occupied by a
person with a smaller build (e.g. a teenager
or small adult), either the AIRBAG ON> or OFF> indicator light lights up and remains
lit after the system self-test depending on
the result of the classification. – If the indi- cator light lights up, move the front
passenger seat as far back as possible.
Alternatively, a person with a small
build can sit on a rear seat.
– If the in- dicator light is lit, a person with a
smaller build should not use the front
passenger seat.

Supplemental Restraint
System (SRS) air bag
warning light
WARNING
If the supplemental air bag warning light is
on, it could mean that the front air bag,
driver's knee air bag, side air bag, curtain
air bag and/or pretensioner systems will
not operate in an accident. To help avoid
injury to yourself or others, have your ve-
hicle checked by an INFINITI retailer as
soon as possible.
When the ignition switch is in the ON posi-
tion, the Supplemental Restraint System
(SRS) air bag warning light illuminates to in-
dicate that the system is operational. The
light then tuns off within a few seconds after
the engine is started.
If any of the following conditions occur, the
front air bag, front seat-mounted side-
impact air bag, roof-mounted curtain air bag
and pretensioner systems need servicing:
•The supplemental air bag warning light
remains on for longer than a few seconds
once the engine is running.
•The supplemental air bag warning light
flashes intermittently.
•The supplemental air bag warning light
does not come on at all.
It is recommended you visit an INFINITI re-
tailer for these services. Unless checked and
repaired, the supplemental restraint system
(air bag system) and/or the pretensioner sys-
tems may not function properly. For addi-
tional information, refer to "Supplemental
Restraint System (SRS)" in the "1. Safety —
seats, seat belts and supplemental restraint
system" section.
Coolant warning light
WARNING
If the coolant warning light is lit, the engine
may not be being cooled sufficiently and
may be damaged.
Never drive with an overheated engine.
Driving when your engine is overheated
can cause some fluids which may have
leaked into the engine compartment to
catch fire.
In addition, steam from an overheated en-
gine can cause serious burns, which can oc-
cur just by opening the hood.
There is a risk of injury
If the red coolant warning light lights up while
the engine is running and the coolant tem-
perature gauge is at the start of the scale, the temperature sensor for the coolant tempera-
ture gauge is faulty. The coolant temperature
is no longer being monitored. There is a risk of
engine damage if the coolant temperature is
too high.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine. Do not continue driving under
any circumstances.
Consult an INFINITI retailer.
If the red coolant warning light comes on
while the engine is running, with or without
an accompanying warning tone, it could
mean that:•The coolant level is too low.
•If the coolant level is correct, the airflow to
the engine radiator may be blocked or the
electric engine radiator fan may be mal-
functioning.
•The coolant is too hot and the engine is no
longer being cooled sufficiently.
Observe the additional display messages in
the vehicle information display.
Stop the vehicle immediately, paying atten-
tion to road and traffic conditions, and switch
off the engine.
Secure the vehicle against rolling away.

Idle Stop/Start System reminder
chime (if equipped)
The engine will shift to the normal stopped
state if any of the following operations is
made during Idle Stop/Start System activa-
tion, and the Idle Stop/Start System chime
will sound if:
– The vehicle engine hood is open.When the above condition continues for over
3 minutes the Idle Stop/Start System chime
will sound in 5-minute intervals as a reminder
to prevent the possibility of a discharged bat-
tery. Use the ignition switch to turn off the
engine.
Close the hood or the driver’s door, or fasten
the seat belt then restart the engine using the
ignition switch.
For more information, see " Idle Stop/Start
System (if equipped)" in the "5. Starting and
driving" section.

MessagePossible causes/consequences and solutions
[Check Brake Fluid Level]There is insufficient brake fluid in the brake fluid reservoir.
In addition, the redwarning light lights up in the combination meter and a warning tone sounds.
1. Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions. Do not continue driving under any circumstances.
2. Secure the vehicle against rolling away.
3. Check the brake fluid level. If brake fluid is necessary, add fluid and have the system checked. It is recommended you visit an
INFINITI retailer for this service. See "Brake fluid" in the "8. Do-it-yourself" section.
4. If the brake fluid level is correct, have the warning system checked. It is recommended you visit an INFINITI retailer for this service.
WARNING•Your brake system may not be working properly if the warning light is on. Driving could be dangerous. If you judge it to be safe,
drive carefully to the nearest service station for repairs. Otherwise, have your vehicle towed because driving it could be
dangerous.
•Pressing the brake pedal with the engine stopped and/or low brake fluid level may increase your stopping distance and braking
will require greater pedal effort as well as pedal travel.
•If the brake fluid level is below the minimum or MIN mark on the brake fluid reservoir, do not drive until the brake system has
been checked. It is recommended you visit an INFINITI retailer for this service.
[Check Brake Pad Wear] The brake pads/linings have reached their wear limit.
It is recommended you visit an INFINITI retailer.
