2018 INFINITI QX30 speed sensor

How to change the set distance to
the vehicle ahead
The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
To increase the distance to the vehicle ahead,
turn the knob
3toward the rear2.To
decrease the distance to the vehicle ahead,
turn the knob
3toward the front1.
You can see this distance in the vehicle infor-
mation display.
The distance to the vehicle ahead will change
according to the vehicle speed. The higher the
vehicle speed, the longer the distance.
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the system
warns the driver with the chime and distance
warning light. Decelerate by depressing the
brake pedal to maintain a safe vehicle dis-
tance if:
•The chime sounds.
•The distance warning light is illuminated.
The warning chime may not sound and the
distance warning light may not illuminate in
some cases when there is a short distance
between vehicles. Some examples are:
•When the vehicles are traveling at the
same speed and the distance between ve-
hicles is not changing. In this case, the
distance warning light will be on.
•When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing.
•When a vehicle cuts in near your vehicle
•The warning chime will not sound and the
distance warning light will not illuminate
when: – The vehicle approaches other vehicles that are parked or moving slowly. – The accelerator pedal is depressed,
overriding the system.
Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driv-
ing position in the lane) or traffic or vehicle
condition (for example, if a vehicle is being
driven with some damage).
Automatic cancellation
A chime sounds and the message [ICC off] is
displayed in the vehicle information display
for 5 seconds under the following conditions
and the control is automatically canceled.
•The electric parking brake is applied.
•The VDC intervenes or the VDC is deacti-
vated.
•The P (Park), R (Reverse) or N (Neutral)
position is engaged.
•The cruise control lever is pulled in order to
pull away but the front passenger door or
one of the rear doors is open.
•The vehicle is skidding or a wheel slips.
•Active Park Assist is activated.

ICC LIMITATIONS
WARNING
Listed below are the system limitations for
the ICC system. Failure to operate the ve-
hicle in accordance with these system limi-
tations could result in serious injury or
death.
•This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’s re-
sponsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
•The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the sys-
tem in city traffic or congested areas.
•This system will not adapt automati-
cally to road conditions. This system
should be used in evenly flowing traffic.
Do not use the system on roads with
sharp curves, or on icy roads, in heavy
rain or in fog.
•As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive or
absent-minded driving, or overcome poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed
by depressing the brake pedal, depend-
ing on the distance to the vehicle ahead
and the surrounding circumstances in
order to maintain a safe distance be-
tween vehicles.
•If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. Once the
vehicle is stationary, it remains station-
ary and you do not need to depress the
brake pedal.
•Always pay attention to the operation
of the vehicle and be ready to manually
control the proper following distance.
The ICC system may not be able to main-
tain the selected distance between ve-
hicles (following distance) or selected
vehicle speed under some circum-
stances.
•Normally when controlling the distance
to a vehicle ahead, this system auto-
matically accelerates or decelerates
your vehicle according to the speed of
the vehicle ahead. If required, depress
the accelerator to properly accelerate
your vehicle when acceleration is re-
quired for a lane change. Depress the
brake pedal when deceleration is re- quired to maintain a safe distance to the
vehicle ahead due to its sudden braking
or if a vehicle cuts in. Always stay alert
when using the ICC system.
•The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never
use the ICC system under the following
conditions: – On roads where the traffic is heavy or
there are sharp curves.
– On slippery road surfaces such as on
ice or snow, etc.
– During bad weather (rain, fog, snow,
etc.).
– When rain, snow or dirt adhere to the
system sensor.
– On steep downhill roads (the vehicle
may go beyond the set vehicle speed
and frequent braking may result in
overheating the brakes).
– On repeated uphill and downhill
roads.
– When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
– If there is interference by other radar
sources.

[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.
SYSTEM MAINTENANCE
The sensor for the ICC systemAis located
behind the INFINITI logo at the front of the
vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
•Always keep area around the sensor clean.
•Do not strike or damage the areas around
the sensor. Do not touch or remove the
screw located on the sensor. Doing so
could cause failure or malfunction. If the
sensor is damaged due to an accident, it is
recommended you contact an INFINITI re-
tailer.
•Do not cover or attach stickers (including
transparent material) or install an acces-
sory near the sensor. This could cause fail-
ure or malfunction.

Distance warning function
The distance warning function can help you
to minimize the risk of a collision with the
vehicle in front or reduce the effects of such a
collision. If the distance warning function de-
tects that there is a risk of a collision, you will
be warned visually and audibly.
The distance warning function issues a warn-
ing at speeds:
•Of approximately 20 MPH (30 km/h) or
more, if, over several seconds the distance
maintained to the vehicle traveling in front
is insufficient. The distance warning light
then lights up in the combination meter.
•Of approximately 4 MPH (7 km/h) or
more, if you rapidly approach a vehicle in
front. An intermittent warning tone will
then sound and the distance warning light
will light up in the combination meter.
If a warning is issued:
•Brake immediately in order to increase the
distance from the vehicle in front.
or
•Take evasive action provided it is safe to
do so.
WARNING
Due to the nature of the system, particu-
larly complicated but non-critical driving
conditions may also cause the system to
display a warning.
Up to a speed of approximately 45 MPH (70
km/h), the distance warning function can
also react to stationary (stopped or parked)
vehicles.
If you approach a stationary vehicle and the
distance warning function detects a risk of a
collision, the system will alert you both visu-
ally and acoustically.
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.

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.

SYSTEM MAINTENANCE
CAUTION
Keep the surface of the sonar sensors (if
equipped) (located on the front and rear
bumper fascia) free from accumulations of
snow, ice and dirt. Do not scratch the sur-
face of the sonar sensors when cleaning. If
the sensors are covered, the accuracy of
the sonar function will be diminished.During the first 1,200 miles (2,000 km), fol-
low these recommendations to obtain maxi-
mum engine performance and ensure the fu-
ture reliability and economy of your new
vehicle. Failure to follow these recommenda-
tions may result in shortened engine life and
reduced engine performance.
•Avoid driving for long periods at constant
speed, either fast or slow, and do not run
the engine over 4,000 RPM.
•Do not accelerate at full throttle in any
gear.
•Avoid quick starts.
•Avoid hard braking as much as possible.
•Do not tow a trailer for the first 500 mi
(805 km). Your engine, axle or other parts
could be damaged.
You should also observe these notes on
break-in if the engine or parts of the drive
train on your vehicle have been replaced.
CAUTION
In certain driving and driving safety sys-
tems, the sensors adjust automatically
while a certain distance is being driven af-
ter the vehicle has been delivered or after
repairs. Full system effectiveness is not
reached until the end of this teach-in pro-
cess.
Brake pads/linings and rotors that are ei-
ther new or have been replaced only
achieve optimum braking effect after sev-
eral hundred miles of driving. Compensate
for the reduced braking effect by applying
greater force to the brake pedal
BREAK-IN SCHEDULE

Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle at a low
speed in forward or reverse. When the self-
test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal.
This is normal and does not indicate a mal-
function. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates
the ABS warning light on the instrument
panel. The brake system then operates nor-
mally, but without anti-lock assistance. If the
ABS warning light illuminates during the self-
test or while driving, have the vehicle
checked. It is recommended you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies ac-
cording to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the actuator
rapidly applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsation
in the brake pedal and hear a noise from
under the hood or feel a vibration from the
actuator when it is operating. This is normal
and indicates that the ABS is operating prop-
erly. However, the pulsation may indicate
that road conditions are hazardous and extra
care is required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, the VDC system helps to perform
the following functions.
•Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel
on the same axle.
•Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function).
•Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle in the
following conditions: – understeer (vehicle tends to not follow the steered path despite increased
steering input)
– oversteer (vehicle tends to spin due to certain road or driving conditions).
The VDC system can help the driver to main-
tain control of the vehicle, but it cannot pre-
vent loss of vehicle control in all driving situ-
ations.
