2017 INFINITI QX30 brake sensor

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 braking
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 vehicles
•4–30 MPH (7 -50 km/h) for stationary ve-
hicles
Adaptive brake assist function
Adaptive brake assist function provides braking
assistance in hazardous situations at speeds
above 4MPH (7 km/h). It uses radar sensor
technology to assess the traffic situation.
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 increase the braking
force to a level suitable for the traffic condi-
tions.
If the adaptive brake assist function activates,
keep the brake pedal depressed until the emer-
gency 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 func-
tion is capable of reacting to moving objects
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 vehicle in
accordance with these system limitations
could result in serious injury or death.
•The FEB system cannot detect all vehicles
under all conditions.
•The radar sensor does not detect the follow-
ing 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 vehicle
ahead in the following conditions:
– Dirt, ice, snow or other material covering
the radar sensor.
– Interference by other radar sources.
– Snow or heavy rain.
– If the vehicle ahead is narrow (e.g. mo-
torcycle). –
If the vehicle ahead is in a different lane.
– Under strong radar reflections, for ex-
ample, in a multi-level parking garage.
– New vehicle or after a maintenance of the
FEB system. For additional information,
see Break-in schedule later in this sec-
tion
– 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 unnecessarily or give
an unnecessary warning. Always pay care-
ful attention to the traffic situation. Do not
rely solely on the distance warning function
and terminate the intervention if necessary.
•Braking distances increase on slippery sur-
faces.
•The system is designed to automatically
check the sensor’s functionality, within cer-
tain limitations. The system may not detect
some forms of obstruction of the sensor
area such as ice, snow, stickers, for ex-
ample. In these cases, the system may not
be able to warn the driver properly. Be sure
that you check, clean and clear the sensor
area regularly.
•Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
SYSTEM TEMPORARILY UNAVAILABLE

ACTIVE SOUND ENHANCEMENT
The active sound enhancement generates
sounds according to engine speed through the
speakers
2and woofer1(if equipped) to
enhance the quality of the engine sound. IPA is an electronic parking aid with ultrasound.
It detects vehicles and open spaces on both
sides of the vehicle. A parking symbol indicates
a suitable parking space. Active steering inter-
vention can assist you during parking and when
exiting a parking space. The driver controls the
accelerator, brake and gear shift. You may also
use the parking sensor system (see
Parking
sensor system (if equipped) later in this sec-
tion).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute for
your attention to the immediate surround-
ings. The responsibility for safe maneuver-
ing and parking remains with you.
•Make sure that no persons, animals or ob-
jects are in the maneuvering range
•When the parking sensor system is deacti-
vated, IPA is also unavailable.
•While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
•Pay attention to other road users. Stop the
vehicle if necessary or cancel the IPA park-
ing procedure
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
•This system is not designed to prevent con-
tact with small or moving objects.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
CAUTION
Do not drive over obstacles such as curbs, as
you may damage the wheels or tires.
IPA may also display spaces not suitable for
parking, for example:
•Parking or stopping prohibition.
INTELLIGENT PARKING ASSIST (IPA) (IF
EQUIPPED)

•The parking space is bordered by an ob-
stacle, e.g. a tree, a post or a trailer.
1Detected parking space on the left.
2Parking symbol.
3Detected parking space on the right.
IPA is activated automatically when driving for-
wards. The system is operational at speeds of
up to approximately 19 MPH (30 km/h). While in
operation, the system independently locates
and measures parking spaces on both sides of
the vehicle
IPA will only detect parking spaces:
•Adjacent to the vehicle.
•Parallel or at right angles to the direction of
travel.
•That are parallel to the direction of travel and
are at least 5 ft (1.5 m) wide.
•That are parallel to the direction of travel and
at least 3.3 ft (1.0 m) longer than your
vehicle.
•That are at right angles to the direction of
travel and at least 3.3 ft (1.0 m) wider than
your vehicle.
NOTE
IPA cannot measure the length of a parking
space if it is at right angles to the direction of
travel. You will need to judge whether your ve-
hicle will fit in the parking space
When driving at speeds below 19 MPH (30
km/h) you will see parking symbol
2as a
status indicator in the vehicle information dis-
play. When a parking space has been detected,
an arrow towards the right
3or the left1also
appears. IPA only displays parking spaces on
the front-passenger side as standard. Parking
spaces on the driver’s side are displayed as
soon as the turn signal on the driver’s side is
activated. When parking on the driver’s side,
this must remain activated until you confirm the
use of IPA by pressing the button on the
steering wheel. The system automatically deter-
mines whether the parking space is parallel or
at right angles to the direction of travel. A parking space is displayed while you are
driving past it, and until you are approximately
50 ft (15 m) away from it.
PARKING
NOTE
When the parking sensor system detects ob-
stacles, you are responsible for braking in good
time.
1. Stop the vehicle when the parking symbol
shows the desired parking space in the
combination meter
2. Shift into position R. The [Start Park Assist? Yes: OK No:]
message appears in the vehicle information
display.
3. To cancel the procedure: press the
button on the steering wheel or pull away
or
4. To park using IPA press the button on
the steering wheel. The Park Assist [Observe

below 5 MPH (10 km/h). Otherwise, IPA will
be canceled.
7. Stop as soon as the parking sensor system sounds the continuous warning tone, if not
before. Maneuvering may be required in
tight parking spaces.
The [Park Assist active Select D Observe
surroundings] message appears in the ve-
hicle information display.
8. Select transmission position D (Drive) while the vehicle is stationary.
IPA immediately steers in the other direc-
tion.
The [Park Assist Observe surroundings] mes-
sage appears in the vehicle information dis-
play.
NOTE
You will achieve the best results by waiting
for the steering procedure to complete before
pulling away.
9. Drive forwards and be ready to brake at all times.
Maneuvering may be required in tight park-
ing spaces. Drive forward and back up as
prompted by the parking sensor system
warning displays, several times if necessary. 10. Stop as soon as the parking sensor system
sounds the continuous warning tone, if not
before.
The [Park Assist active Select R] [Observe
surroundings] message appears in the ve-
hicle information display.
As soon as the parking procedure is com-
plete the [Park Assist switched off] mes-
sage appears and a warning tone sounds.
The vehicle is now parked.
11. Before leaving the vehicle, secure the ve- hicle against rolling away unintentionally:
•The electric parking brake must be ap-
plied.
•The transmission must be in position P
(Park) and the transmission position dis-
play must show P in the vehicle informa-
tion display.
•The key must be removed from the igni-
tion switch.
•On uphill or downhill gradients, the front
wheels must be turned towards the curb.
IPA no longer supports you with steering inter-
ventions. When IPA is finished, you must steer
again yourself. The parking sensor system is
still available. Parking tips:
•The way your vehicle is positioned in the
parking space after parking is dependent on
various factors. These include the position
and shape of the vehicles parked in front and
behind it and the conditions of the location.
It may be the case that IPA guides you too far
into a parking space, or not far enough into
it. In some cases, it may also lead you across
or onto the curb. If necessary you should
cancel the parking procedure with IPA.
•During the parking maneuver, the system will
indicate when you should shift to R (Reverse)
or D (Drive). However, you can freely choose
to shift gear whenever you feel you need to.
Should the transmission change take place
too early, the parking procedure will be
canceled. A sensible parking position can no
longer be achieved from this position.
EXITING A PARKING SPACE
In order that IPA can support when exiting the
parking space:
•You need to have parked using IPA.
•The border of the parking space must be high
enough at the front and the rear. A curb
stone is too small, for example.
Starting and driving5-71

•The border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45 degrees to the
starting position as it is manoeuvred into the
parking space.
•A total front and back maneuvering distance
of at least 1.0 m must be available.
IPA can only assist you with exiting a parking
space if you have parked the vehicle parallel to
the direction of travel using IPA.
WARNING
•IPA is only an aid. It is not a substitute for
your attention to the immediate surround-
ings. The responsibility for safe maneuver-
ing and parking remains with you.
•Make sure that no persons, animals or ob-
jects are in the maneuvering range.
•When the parking sensor system is deacti-
vated, IPA is also unavailable.
•While parking or pulling out of a parking
space, the vehicle swings out and can drive

mately 5 MPH (10 km/h) when exiting a park-
ing space. Otherwise, IPA will be canceled.
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
cause you to collide with other road users.
There is a risk of an accident.
9. Depending on the message or as required, shift the transmission to position D or R.
IPA immediately steers in the other direc-
tion. The [Observe surroundings] message
appears in the display.
NOTE
You will achieve the best results by waiting
for the steering procedure to complete before
pulling away.
If you back up after activation, the steering
wheel is moved to the straight-ahead posi-
tion.
10. Drive forward and back up as prompted by the parking sensor system warning dis-
plays, several times if necessary.
Once you have exited the parking space com-
pletely, the steering wheel is moved to the
straight-ahead position. You hear a tone and
the [Park Assist switched off] message appears
in the display. You will then have to steer and
5-72Starting and driving

merge into traffic on your own. The parking
sensor system is still available. You can take
over the steering before the vehicle has exited
the parking space completely. This is useful, for
example when you recognise that it is already
possible to pull out of the parking space.
CANCELING IPA
Stop the movement of the steering wheel or
steer yourself. IPA will be immediately can-
celed. The [Park Assist canceled] message ap-
pears in the vehicle information display.

•You are driving faster than 5 MPH (10 km/h)
•A wheel spins and VDC intervenes or fails.
Thewarning light lights up in the
combination meter.
A warning tone sounds. The parking symbol
disappears and the vehicle information display
shows the [Park Assist canceled] message.
When IPA is canceled, you must steer again
yourself.
WARNING
•The parking sensor system is a convenience
but it is not a substitute for proper parking.
Always look around and check that it is safe
to do so before parking. Always move
slowly.
•Read and understand the limitations of the
parking sensor system as contained in this
section. Inclement weather may affect the
function of the parking sensor system; this
may include reduced performance or a false
activation.
•This system is not designed to prevent con-
tact with small or moving objects.
•The system is designed as an aid to the
driver in detecting large stationary objects
to help avoid damaging the vehicle. The
system will not detect small objects below
the bumper, and may not detect objects that
are too close to the bumper or on the
ground.
•If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inac-
curate measurement of obstacles or false
alarms.
