2018 INFINITI QX30 Radar sensors dirty

Message Possible causes/consequences and solutions
[Radar Sensor (See
Operator's Manual):]At least one of the following driving systems or driving safety systems is temporarily restricted or inoperative:
•Forward Emergency Braking•Intelligent Cruise Control•Blind Spot Warning
Possible causes:
•The sensors in the radiator trim and/or at the sides of the rear bumpers are dirty.•The function of the driving system and/or driving safety system is impaired due to heavy rain or snow.
A warning tone also sounds.
Once the causes listed above no longer apply, the display message goes out. All driving systems/driving safety systems are
operative 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. 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. The
warning 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)".

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations for
the FEB system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•The FEB system cannot detect all ve-
hicles under all conditions.
•The radar sensor does not detect the
following objects:
–Pedestrians or animals
–Oncoming vehicles
–Crossing vehicles
•The radar sensor has some performance
limitations. For stationary vehicles, the
FEB system will not function when the
vehicle is driven at speeds over:
–
Approximately 31 MPH (50 km/h) for
the Autonomous braking function.
•The radar sensor may not detect a ve-
hicle ahead in the following conditions:
–Dirt, ice, snow or other material cov-
ering the radar sensor.
–Interference by other radar sources.
–Snow or heavy rain.
–If the vehicle ahead is narrow (e.g.
motorcycle).–If the vehicle ahead is in a different
lane.
–Under strong radar reflections, for
example, in a multi-level parking ga-
rage.
–New vehicle or after a maintenance
of the FEB system. For additional in-
formation, see "Break-in schedule"
later in this section
–When driving on a steep downhill
slope or roads with sharp curves.
–When towing a trailer.
•In some road or traffic conditions, the
FEB system may intervene unnecessar-
ily or give an unnecessary warning. Al-
ways pay careful attention to the traffic
situation. Do not rely solely on the dis-
tance warning function and terminate
the intervention if necessary.
•Braking distances increase on slippery
surfaces.
•The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
for example. In these cases, the system
may not be able to warn the driver prop-
erly. Be sure that you check, clean and
clear the sensor area regularly.
•Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
SYSTEM TEMPORARILY
UNAVAILABLE
If the FEB stops working due to a malfunc-
tion or some other reason, one of the follow-
ing three messages will be displayed in the
vehicle information display.
•[Emergency Brake Currently Unavailable
See Operator's Manual]
•[Emergency Brake Inoperative]
•[Radar Sensors Dirty See Operator's
Manual]
For each of these messages, possible causes
and solutions are listed below.
[Emergency Brake Currently Unavailable
See Operator's Manual]:The FEB system is
temporarily inoperative. Possible causes:
•The radar sensor system is temporarily in-
operative, for example, due to electro-
magnetic radiation emitted by nearby TV
or radio stations or other sources of elec-
tromagnetic radiation.

•The system is outside the operating tem-
perature range.
•The on-board voltage is too low.
Once the causes listed above no longer apply,
the display message goes out. The FEB sys-
tem is operative again.
If the display message does not disappear:
•Pull over and stop the vehicle safely as
soon as possible, paying attention to road
and traffic conditions.
•Secure the vehicle against rolling away.
•Switch off the engine.
[Emergency Brake Inoperative]:The FEB
system is temporarily inoperative due to a
malfunction. The adaptive brake assist func-
tion may also have failed.
It is recommended you visit an INFINITI re-
tailer.
[Radar Sensors Dirty See Operator's
Manual]:The FEB system is temporarily re-
stricted or inoperative. Possible causes:
•The sensor behind the INFINITI logo is dirty.
•The function of the FEB system is im-
paired due to heavy rain or snow.
A warning tone also sounds.Once the causes listed above no longer apply,
the display message goes out. The FEB sys-
tem is operative again.
If the display message does not disappear:
•Pull over and stop the vehicle safely as
soon as possible, paying attention to road
and traffic conditions.
•Secure the vehicle against rolling away.
•Switch off the engine.
•Clean the area around the sensors.
•Restart the engine. The display message
disappears.
SYSTEM MAINTENANCE
The sensorAis located behind the INFINITI
logo at the front of the vehicle.
To keep the system operating properly, be
sure to observe the following:
•Always keep the sensor area of the
INFINITI logo clean.
•Do not strike or damage the areas around
the sensor.
•Do not cover or attach stickers or similar
objects on the front bumper near the sen-
sor area. This could cause failure or mal-
function.
•Do not attach metallic objects near the
sensor area (brush guard, etc.). This could
cause failure or malfunction.
•Do not alter, remove or paint the front
grille or INFINITI logo.
