Message Possible 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. SeeBrake fluidin the8. Do-it-yourselfsection.
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.
[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.

[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 (seeFront passenger air bag and
status lightin the1. Safety — seats, seat belts and supplemental restraint systemsection)
- 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 the conditions are not met, the system is not operating correctly.
Have the system checked immediately. It is recommended you visit an INFINITI retailer for this service.

[Check Coolant Level See
Operators Manual]The coolant level is too low.CAUTIONAvoid making long journeys with too little coolant in the engine cooling system. The engine will otherwise be damaged.
Top up the coolant, observing the warning notes before doing so (seeIf your vehicle overheatsin the6. In case of emergencysection).
If the coolant needs topping up more often than usual. have the engine coolant system checked. It is recommended you visit an INFINITI
retailer for this service.
The fan motor is faulty.
If the coolant temperature is below 250oF (120oC), you can continue driving to the nearest place you can have the system checked. It
is recommended that you visit an INFINITI retailer for this service.
Avoid putting the engine under heavy load as you do so, e.g. driving in mountainous terrain and stop-start traffic.

hicle Turn Engine Off]The coolant is too hot.
A warning tone also sounds.
CAUTIONIf the gauge indicates coolant temperature near the hot (H) end of the normal range, reduce vehicle speed to decrease temperature. If the
gauge is over the normal range, stop the vehicle as soon as safely possible. If the engine is overheated, continued operation of the vehicle
may seriously damage the engine. For additional information, refer toIf your vehicle overheatsin the6. In case of emergencysection for
immediate action required.
1. Stop the vehicle immediately, paying attention to road and traffic conditions, and switch off the engine.
2. Secure the vehicle against rolling away
3. Wait until the engine has cooled down.
4. Make sure that the air supply to the engine radiator is not blocked, e.g. by frozen slush.
5. Do not start the engine again until the display message goes out and the coolant temperature is below 120
oC. The engine may
otherwise be damaged.
6. Pay attention to the coolant temperature display.
7. If the temperature increases again, have the system checked immediately. It is recommended you visit an INFINITI retailer for this
service.
Under normal operating conditions and with the specified coolant level, the coolant temperature may rise to 250
oF (120oC).
