brake sensor INFINITI QX30 2017 User Guide

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 (seeParking
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 bumper
fascia, leaving it misaligned or bent, the sens-
ing zone may be altered causing inaccurate
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 bumper
fascia, leaving it misaligned or bent, the sens-
ing zone may be altered causing inaccurate
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.
•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 incor-
rectly.
•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 parking
space being measured inaccurately.
•Pay attention to the parking sensor system
warning messages during the parking proce-
dure.
•You can intervene in the steering procedure
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 fitted.
•Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
INTELLIGENT PARKING ASSIST (IPA) (IF
EQUIPPED)
5-68Starting and driving

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 thebutton 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.

11. Before leaving the vehicle, secure the ve-
hicle against rolling away unintentionally:
•The electric parking brake must be applied.
•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
ignition 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.
•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

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
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.

•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.
PARKING SENSOR SYSTEM (IF EQUIPPED)
Starting and driving5-73

The parking sensor system is activated auto-
matically when you:
•Switch on the ignition
•Shift to position D (Drive), or R (Reverse) on
vehicles with automatic transmission
•Release the electric parking brake
The parking sensor system is deactivated at
speeds above 10 MPH (16 km/h). It is reacti-
vated at lower speeds.
The parking sensor system is deactivated for
the rear area when you establish an electrical
connection between your vehicle and a trailer.
RANGE OF THE SENSORS
The parking sensor system does not take into
account obstacles located:
•Below the detection range, e.g. persons,
animals or objects.
•Above the detection range, e.g. overhanging
loads, tail sections or loading ramps of
goods vehicles.
The sensors must be free of dirt, ice and slush.
Otherwise, they may not function correctly.
Clean the sensors regularly, taking care not to
scratch or damage them.
PARKING SENSOR SYSTEM OFF
SWITCH
The parking sensor system OFF switch2on
the lower side of the instrument panel allows
the driver to turn the parking sensor system on
and off. To turn the parking sensor system on
and off, the ignition switch must be in the ON
position. The indicator light
1on the switch
will illuminate when the system is turned off.
The parking sensor system will turn on auto-
matically when the ignition switch is turned
from the OFF position to the ON position.

CAUTION
In certain driving and driving safety systems,
the sensors adjust automatically while a cer-
tain distance is being driven after the vehicle
has been delivered or after repairs. Full system
effectiveness is not reached until the end of
this teach-in process.
Brake pads/linings and rotors that are either
new or have been replaced only achieve opti-
mum braking effect after several hundred
miles of driving. Compensate for the reduced
braking effect by applying greater force to the
brake pedalFollow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.
1.Use Smooth Accelerator and Brake Pedal
Application
•Avoid rapid starts and stops.
•Use smooth, gentle accelerator and brake
application whenever possible.
•Maintain constant speed while commut-
ing and coast whenever possible.
2.Maintain Constant Speed
•Look ahead to try and anticipate and
minimize stops.
•Synchronizing your speed with traffic lights
allows you to reduce your number of stops.
•Maintaining a steady speed can minimize
red light stops and improve fuel efficiency.
3.Use Air Conditioning (A/C) at Higher Vehicle
Speeds
•Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load.
•Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle due
to increased aerodynamic drag.
•Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4.Drive at Economical Speeds and Distances
•Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where legally
allowed) can improve fuel efficiency due
to reduced aerodynamic drag.
•Maintaining a safe following distance
behind other vehicles reduces unneces-
sary braking.
•Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
•Select a gear range suitable to road
conditions.
5.Use Cruise Control
•Using cruise control during highway driv-
ing helps maintain a steady speed.
•Cruise control is particularly effective in
providing fuel savings when driving on
flat terrains.
Utilize a map or navigation system to determine
the best route to save time.
FUEL EFFICIENT DRIVING TIPS
5-82Starting and driving

Tire type and condition may also affect braking
effectiveness.
–When replacing tires, install the specified
size of tires on all four wheels.
–
When installing a replacement tire, make sure
that it is the proper size and type as specified on
the tire and loading information label. (See
Wheels and Tiresin the9. Maintenance and
Schedulessection.)
–For detailed information, seeWheels and
tiresin the8. Do-it-yourselfsection.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to
prevent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady pres-
sure, but do not pump the brakes. The ABS will
operate to prevent the wheels from locking up.
Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer.
The computer has a built-in diagnostic feature
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 malfunction. If the computer
senses a malfunction, it switches the ABS off
and illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, 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 according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. 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 properly. However, the pulsa-
tion may indicate that road conditions are haz-
ardous and extra care is required while driving.
Starting and driving5-89

The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and
vehicle motion. Under certain driving condi-
tions, 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 condi-
tions:
– understeer (vehicle tends to not follow
the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to
certain road or driving conditions).
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.When the VDC system operates, the VDC warn-
ing light in the instrument panel flashes so note
the following:
•The road may be slippery or the system may
determine some action is required to help
keep the vehicle on the steered path.
•You may feel a pulsation in the brake pedal
and hear a noise or vibration from under the
hood. This is normal and indicates that the
VDC system is working properly.
•Adjust your speed and driving to the road
conditions.
SeeVehicle Dynamic Control (VDC) warning
lightin the2. Instruments and controlssec-
tion.
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
WARNING
•The VDC system is designed to help the
driver maintain stability but does not pre-
vent accidents due to abrupt steering opera-
tion at high speeds or by careless or danger-
ous driving techniques. Reduce vehicle
speed and be especially careful when driv-
ing and cornering on slippery surfaces and
always drive carefully.
•Do not modify the vehicle’s suspension. If
suspension parts such as shock absorbers,
struts, springs, stabilizer bars, bushings
and wheels are not INFINITI recommended
for your vehicle or are extremely deterio-
rated, the VDC system may not operate
properly. This could adversely affect vehicle
handling performance, and the VDC warning
light
may illuminate.
•If brake related parts such as brake pads,
rotors and calipers are not INFINITI recom-
mended or are extremely deteriorated, the
VDC system may not operate properly and
the VDC warning light
may illuminate.
•If engine control related parts are not
INFINITI recommended or are extremely de-
teriorated, the VDC warning light
may
illuminate.

•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light
will flash for approximately 1 minute. The
light will remain on after 1 minute. It is rec-
ommended you Contact an INFINITI retailer
as soon as possible for tire replacement
and/or system resetting.
•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 repairing or re-
placing the tire. It is recommended 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) appears
in the vehicle information display, one or more
of your tires is significantly under-inflated. If
the vehicle is being driven with low tire pres-
sure, the TPMS will activate and warn you of it
by the low tire pressure warning light (in the
meter panel). This system will activate only
when the vehicle is driven at speeds above 16MPH (25 km/h).
