Radar sensors INFINITI QX30 2018 User Guide

RADAR MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper.
Always keep the area near the radar sensors
clean.
The radar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog.
The blocked condition may also be caused by
objects such as ice, frost or dirt obstructing
the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors.
Do not attach stickers (including transparent
material), install accessories or apply addi-
tional paint near the radar sensors.Do not strike or damage the area around the
radar sensors. It is recommended you consult
an INFINITI retailer if the area around the
radar sensors is damaged due to a collision.
FCC NOTICE
For USA:
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions: (1) This device may not
cause harmful interference, and (2) this de-
vice must accept any interference received,
including interference that may cause unde-
sired operation.
NOTE
Changes or modification not expressly ap-
proved by the party responsible for compli-
ance could void the user’s authority to oper-
ate the equipment.
For Canada:
This device complies with Industry Canada
license-exempt RSS standard(s). Operation
is subject to the following two conditions: (1)
this device may not cause harmful interfer-
ence, and (2) this device must accept any
interference received, including interference
that may cause undesired operation of the
device.Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the ve-
hicle is laden or towing a trailer.WARNING
For vehicles with automatic transmission,
you need to have selected manual drive
program M (see "Manual drive program"
earlier in this section). By doing so, you will
make use of the braking effect of the en-
gine. This relieves the load on the brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic
conditions are appropriate for maintaining a
steady speed for a prolonged period. You can
set the cruise control at any road speed
above 20 MPH (30 km/h).
The speed indicated in the speedometer may
differ slightly from the set speed.

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.
