2Distance warning light
3Forward emergency braking OFF display The FEB system consists of a distance warn-
ing function with an autonomous emergency
braking function and adaptive brake assist
function.
The FEB system 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 FEB system detects that there is a risk
of a collision, you will be warned visually and
audibly. If you do not react to the visual and
audible collision warning, autonomous brak-
ing can be initiated in critical situations. If you
apply the brake yourself in a critical situation,
the adaptive brake assist function assists
you.

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.

Distance warning light
Starting and driving5-65
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 re-
acts 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.
NSD630
Starting and driving5-67
•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.

IPA is an electronic parking aid with ultra-
sound. It detects vehicles and open spaces on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention 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 Camera Aid-
ing Sonar (parking sensor) function (see "
Camera Aiding Sonar (parking sensor) func-
tion (if equipped)" later in this section).
IMPORTANT SAFETY NOTES
WARNING
•IPA is only an aid. It is not a substitute
for your attention to the immediate sur-
roundings. The responsibility for safe
maneuvering and parking remains with
you.
•Make sure that no persons, animals or
objects are in the maneuvering range
•When the sonar (parking sensor) func-
tion is deactivated, IPA is also unavail-
able.
•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
parking procedure
•This system is not designed to prevent
contact with small or moving objects.
•If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
•This system is not designed to prevent
contact with small or moving objects.
•If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles 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.
•In front of driveways or entrances and
exits.
•Unsuitable surfaces.
Parking tips:
•On narrow roads, drive as closely as pos-
sible past the parking space.
•Parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
•Parking spaces that are partly occupied by
trailer towing bars might not be identified
as such or be measured incorrectly.
•Snowfall or heavy rain may lead to a park-
ing space being measured inaccurately.
•Pay attention to the sonar function warn-
ing messages during the parking proce-
dure.
•You can intervene in the steering proce-
dure to correct it at any time. IPA will then
be canceled.
•When transporting a load which protrudes
from your vehicle, you should not use IPA.
•Never use IPA when snow chains are fit-
ted.
•Make sure that the tire pressures are al-
ways correct. This has a direct influence on
the parking characteristics of the vehicle.
INTELLIGENT PARKING ASSIST (IPA)
(IF EQUIPPED)
Starting and driving5-71
1Detected parking space on the left.
2Parking symbol.
3Detected parking space on the right.
IPA is activated automatically when driving
forwards. The system is operational at
speeds of up to approximately 19 MPH (30
km/h). While in operation, the system inde-
pendently 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
vehicle 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
display. When a parking space has been de-
tected, an arrow towards the right
3or the
left
1also appears. IPA only displays park-
ing 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
tem automatically determines 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 approxi-
mately 50 ft (15 m) away from it.
PARKING
NOTE
When the sonar function detects obstacles,
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 informa-
tion display.
3. To cancel the procedure: press the
button on the steering wheel or pull away
or
4. To park using IPA press the
on the steering wheel. The Park Assist
[Observe surroundings] message appears
in the vehicle information display.
5. Release the steering wheel.
6. Back up the vehicle, being ready to brake at all times. When backing up, drive at a
speed below 5 MPH (10 km/h). Other-
wise, IPA will be canceled.

7. Stop as soon as the sonar function soundsthe continuous warning tone, if not be-
fore. 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]
message appears in the vehicle informa-
tion display.
NOTE
You will achieve the best results by wait-
ing for the steering procedure to com-
plete before pulling away.
9. Drive forwards and be ready to brake at all times.
Maneuvering may be required in tight
parking spaces. Drive forward and back
up as prompted by the IPA and sonar
function warning displays, several times if
necessary. 10. Stop as soon as the sonar function
sounds the continuous warning tone, if
not before.
The [Park Assist active Select R] [Ob-
serve surroundings] message appears in
the vehicle information display.
As soon as the parking procedure is
complete the [Park Assist switched off]
message 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
display must show P in the vehicle
information display.
•The key must be removed from the
ignition switch.
•On uphill or downhill gradients, the
front wheels must be turned towards
the curb.
IPA no longer supports you with steering in-
terventions. When IPA is finished, you must
steer again yourself. The sonar function 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 posi-
tion 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.
