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.
•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.

sonar function is still available. You can take
over the steering before the vehicle has ex-
ited the parking space completely. This is use-
ful, for example when you recognize 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
appears in the vehicle information display.
or
Press the sonar function OFF switch. The
sonar function is switched off and IPA is
immediately canceled The [Park Assist can-
celed] message appears in the vehicle infor-
mation display.
IPA is canceled automatically if:
•The electric parking brake is applied
•Parking using IPA is no longer possible
•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 dis-
play shows the [Park Assist canceled] mes-
sage.
When IPA is canceled, you must steer again
yourself.
WARNING
•The sonar function 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 sonar function as contained in this
section. Inclement weather may affect
the function of the sonar function; this
may include reduced performance or a
false activation.
•The driver is always responsible for
safety during parking and other maneu-
vers.
•The system is designed as an aid to the
driver in detecting large stationary ob-
jects 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.
•Always look around and check that it is
safe to move before parking.

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

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.

function and the low tire pressure warn-
ing light will flash for approximately 1
minute. The light will remain on after 1
minute. It is recommended you Contact
an INFINITI retailer as soon as possible
for tire replacement and/or system re-
setting.
•Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
•If you used Emergency Tire Sealant to
repair a minor tire puncture, the TPMS
sensor should be checked when repair-
ing or replacing the tire. It is recom-
mended you visit an INFINITI retailer for
this service.
The Tire Pressure Monitoring System (TPMS)
monitors tire pressure of all tires. When the
low tire pressure warning light is lit, and a tire
pressure-related warning (if equipped) ap-
pears in the vehicle information display, one
or more of your tires is significantly under-
inflated. If the vehicle is being driven with low
tire pressure, the TPMS will activate and
warn you of it by the low tire pressure warn-
ing light (in the meter panel). This system will
activate only when the vehicle is driven at
speeds above 16 MPH (25 km/h). For more details about the TPMS, see "Tire
Pressure Monitoring System (TPMS)" in the
"5. Starting and driving" section.
