2018 INFINITI QX30 Radar sensor

is covered with ice, a transparent or translu-
cent vinyl bag, etc., the ICC system may not
detect them. In these instances, the ICC sys-
tem may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead.
If the ICC system stops working due to a
malfunction or some other reason, one of the
following messages will be displayed in the
vehicle information display
2.
•[ICC off]
•[ICC Now Available]
•[ICC Currently Unavailable See Operator's
Manual]
•[ICC Inoperative]
•[ICC Suspended]
•[ICC– – – MPH]
[ICC off]:The ICC system has been deacti-
vated. If it was not deactivated by the driver,
a warning tone also sounds.
[ICC Now Available]:The ICC system is op-
erational again after having been temporarily
unavailable. You can now reactivate the ICC
system.[ICC Currently Unavailable See Operator's
Manual]:The ICC system is temporarily inop-
erative. Possible causes:
•The function is impaired due to heavy rain
or snow.
•The radar sensor system is temporarily in-
operative, e. g. due to electromagnetic ra-
diation emitted by nearby TV or radio sta-
tions or other sources of electromagnetic
radiation.
•The system is outside the operating tem-
perature range.
•The on-board voltage is too low.
A warning tone also sounds.
Once the causes listed above no longer apply,
the display message goes out.
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.
•Restart the engine.[ICC Inoperative]:The ICC system is mal-
functioning. The adaptive brake assist func-
tion may also have failed. A warning tone also
sounds. Have the system checked. It is rec-
ommended you visit an INFINITI retailer for
this service.
[ICC Suspended]:You have depressed the
accelerator pedal. The ICC system is no lon-
ger controlling the speed of the vehicle.
The display message should disappear when
you remove your foot from the accelerator
pedal
[ICC–––MPH]:An activation condition for
the ICC system is not fulfilled.
Check the activation conditions for the ICC
system.

The FEB system uses a radar sensorAlo-
cated behind the INFINITI logo to measure
the distance to the vehicle ahead in the trav-
eling lane.
FEB SYSTEM OPERATION
1Steering wheel mounted controls (left side)
2Distance warning light
3Forward emergency braking OFF displayThe FEB system consists of a distance warn-
ing function with an autonomous emergency
braking function and adaptive brake assist
function.

Autonomous braking function
If the driver does not react to the distance
warning signal in a critical situation, the FEB
system can assist with the autonomous brak-
ing function
The autonomous braking function can help
the driver to avoid an accident or reduces the
effects of an accident.
The autonomous braking function is available
in the following speed ranges:
•4–125 MPH (7-200 km/h) for moving ve-
hicles
•4–30 MPH (7 -50 km/h) for stationary
vehicles
Adaptive brake assist function
Adaptive brake assist function provides brak-
ing assistance in hazardous situations at
speeds above 4 MPH (7 km/h). It uses radar
sensor technology to assess the traffic situa-
tion.
If the system detects a risk of collision with
the vehicle in front, it calculates the braking
force necessary to avoid a collision. If you
apply the brakes forcefully, the adaptive
brake assist function will automatically in-
crease the braking force to a level suitable for
the traffic conditions.If the adaptive brake assist function acti-
vates, keep the brake pedal depressed until
the emergency braking situation is over. ABS
prevents the wheels from locking.
The brakes will work normally again if:
•You release the brake pedal.
•There is no longer any danger of a collision.
•No obstacle is detected in front of your
vehicle.
The brake assist function is then deactivated.
At high speeds, the adaptive brake assist
function is capable of reacting to moving ob-
jects that have already been detected as such
at least once over the period of observation.
Up to a speed of approximately 45 MPH
(70 km/h), the adaptive brake assist function
reacts to stationary vehicles.

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.
Starting and driving5-67

•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.
