ECU INFINITI QX30 2018 Owner's Guide

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.

MessagePossible causes/consequences and solutions
[Emergency Brake
Currently Unavailable See
Operator's Manual] Forward Emergency Braking is temporarily inoperative.
Possible causes:
•The radar sensor system is temporarily inoperative, e.g. due to electromagnetic radiation emitted by nearby TV or radio stations
or other sources of electromagnetic radiation.
•The system is outside the operating temperature range.•The on-board voltage is too low.
Once the causes listed above no longer apply, the display message goes out.
Forward Emergency Braking is operational again.
If the display message does not disappear:
1. Pull over and stop the vehicle safely as soon as possible, paying attention to road and traffic conditions.
2. Secure the vehicle against rolling away.
3. Restart the engine.
[Emergency Brake Inop-
erative] Forward Emergency Braking is temporarily inoperative due to a malfunction.
Have the system checked. It is recommended you visit an INFINITI retailer for this service.

2. Secure the vehicle against rolling away.
3. Switch off the engine.
4. Clean the sensors in the following locations: - In the radiator trim
- At the sides of the rear bumper
5. Restart the engine. The display message disappears.
[SRS Malfunction Service
Required] The restraint system needs servicing. Thewarning light also lights up in the combination meter.
It is recommended you visit an INFINITI retailer for these services.
Unless checked and repaired, the Supplemental Restraint Systems and/or the pretensioner seat belt may not function properly.
WARNING
If this light is on, it could mean that the front air bag, side air bag, curtain air bag systems and/or pretensioner systems will not
operate in an accident. To help avoid injury to yourself or others, have your vehicle checked as soon as possible. It is recommended
you visit an INFINITI retailer for this service.
For further information about the restraint system, see "Supplemental Restraint System (SRS)" in the "1. Safety — seats, seat belts and

[Front Passenger Airbag
Disabled See Operator's
Manual] The front-passenger front air bag is disabled during the journey although an adult or person of corresponding stature is on the front
passenger seat.
Front passenger seat adult occupants who are properly seated and using the seat belt as outlined in this manual should not cause
the front passenger air bag to be automatically turned OFF. For small adults it may be turned OFF, however if the occupant takes
his/her weight off the seat cushion (for example, by not sitting upright, by sitting on an edge of the seat, or by otherwise being out
of position), this could cause the sensor to turn the air bag OFF. Always be sure to be seated and wearing the seat belt properly for
the most effective protection by the seat belt and supplemental air bag.
If additional forces are applied to the seat, the system may interpret the occupant's weight as lower than it actually is.
1. Stop the vehicle in a safe area away from traffic as soon as possible, paying attention to road and traffic conditions.
2. Secure the vehicle against rolling away.
3. Switch the ignition off.
4. Have the occupant on the front-passenger seat step out of the vehicle.
5. Make sure that the seat is unoccupied, close the front passenger door and switch on the ignition.
6. Observe the indicator lights in the center console and the vehicle information display and check the
following. Seat unoccupied and ignition switched on:
- The and indicator lights must light up simultaneously for
approximately six seconds.
- The indicator lights must then light up and remain lit. If the indicator light is on, the automatic
front-passenger front air bag deactivation system has disabled the front-passenger front air bag (see "Front passenger air bag
and status light" in the "1. Safety — seats, seat belts and supplemental restraint system" section)
- the [Front Passenger Airbag Enabled See Operator's Manual] or [Front Passenger Airbag Disabled See Operator's Manual]
display messages must not be shown in the vehicle information display.
7. Wait for a period of at least 60 seconds until the necessary system checks have been completed.
8. Make sure that the display messages do not appear in the vehicle information display.
If these conditions are met, the front-passenger seat can be occupied again. Whether the or
indicator light remains lit or goes out depends on how the automatic front passenger front air bag deactivation system classifies the
occupant.
If, after taking the steps above, you still believe the system is not operating properly, have it checked immediately. It is recommended
you visit an INFINITI retailer for this service.

light" in the "1. Safety — seats, seat belts and supplemental restraint system" section).

1. Stop the vehicle in a safe area away from traffic as soon as possible, paying attention to road and traffic conditions.
2. Secure the vehicle against rolling away.
3. Switch the ignition off.
4. Open the front-passenger door.
5. Remove the child and the child restraint system from the front passenger seat.
6. Make sure there are no objects applying additional force to the seat. The system may otherwise detect the additional force and interpret the seat occupant's weight as greater than it actually is.
