brake sensor INFINITI QX60 2020 Owner's Guide

The VDC system uses various sensors to
monitor driver inputs and vehicle motion. Un-
der certain driving conditions, the VDC sys-
tem 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 out- put 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 fol- low the steered path despite in-
creased 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.
When the VDC system operates, the
indicator light in the instrument panel flashes
to 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 indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip indi-
cator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instruments
and controls” section of this manual.
If a malfunction occurs in the system,
the
andindicator lights come on
in the instrument panel. The VDC system au-
tomatically turns off when these indicator
lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light and
the FEB with Pedestrian Detection system
warning light illuminate to indicate the VDC
system is off.
When the VDC OFF switch is used to turn off
the system, the VDC system still operates to
prevent one drive wheel from slipping by
transferring power to a non-slipping drive
wheel. The
indicator light flashes if this occurs. All other VDC functions are off and
the
indicator light will not flash.
The VDC system is automatically reset to on
when the ignition switch is placed in the OFF
position then back to the ON position.
The computer has a built-in diagnostic fea-
ture that tests the system each time you start
the engine and move the vehicle forward or in
reverse at a slow speed. When the self-test
occurs, you may hear a clunk noise and/or
feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunc-
tion.
WARNING
∙ The VDC system is designed to help the driver maintain controllability but does
not prevent accidents due to abrupt
steering operation at high speeds or by
careless or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-140Starting and driving

When the vehicle is stopped on a hill, the hill
start assist system automatically keeps the
brakes applied to help prevent the vehicle
from rolling backward in the time it takes the
driver to release the brake pedal and apply
the accelerator.
The hill start assist system will operate auto-
matically under the following conditions:∙ The transmission is shifted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maximum
holding time is 2 seconds. After 2 sec-
onds the vehicle will begin to roll back and
the hill start assist system will stop oper-
ating completely.
The hill start assist system will not operate
when the shift lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The sonar system sounds a tone to inform the
driver of obstacles near the bumper.
When the sonar system is turned on, the
sonar view will automatically appear in the
center display when the camera is activated.
WARNING
Failure to follow the warnings and instruc-
tions for proper use of the sonar system
could result in serious injury or death.
∙ The sonar system is not a replacement for
proper driving procedures and is not de-
signed to prevent contact with vehicles
or objects. ∙ The driver is always responsible for
safety during parking and other maneu-
vers. Always look around and check that
it is safe to do so before parking.
∙ This function is designed as an aid to the driver in detecting large stationary ob-
jects to help avoid damaging the vehicle.
If your vehicle sustains damage to the bum-
per fascia, leaving it misaligned or bent, the
sensing zone may be altered causing inaccu-
rate measurement of obstacles or false
alarm.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window) will
interfere with the tone and it may not be
heard.
∙ Keep the sonar sensors (located on the bumper fascias) free from snow, ice and
large accumulations of dirt. Do not clean
the sensors with sharp objects. If the sen-
sors are covered, the accuracy of the so-
nar function will be diminished.

SONAR LIMITATIONS
WARNING
Listed below are the system limitations for
the sonar system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
∙ Read and understand the limitations of the sonar system as contained in this sec-
tion. Inclement weather may affect the
function of the sonar system; this may
include reduced performance or a false
activation.
∙ The system is deactivated at speeds above 6 mph (10 km/h). It is reactivated
at lower speeds.
∙ Inclement weather or ultrasonic sources such as an automatic car wash, a truck’s
compressed-air brakes or a pneumatic
drill may affect the function of the sys-
tem; this may include reduced perfor-
mance or a false activation.
∙ The system is not designed to prevent contact with small or moving objects. Al-
ways move slowly. The system will not
detect small objects below the bumper or
on the ground. ∙ The system may not detect the following
objects: fluffy objects such as snow,
cloth, cotton, glass-wool, etc.; thin ob-
jects such as rope, wire and chain, etc.; or
wedge-shaped objects.
∙ The system may not detect objects at speeds above 3 mph (5 km/h) and may
not detect certain angular or moving
objects.
SYSTEM TEMPORARILY
UNAVAILABLE
When sonar blockage is detected, the system
will be deactivated automatically.
The system is not available until the condi-
tions no longer exist.
The sonar sensors may be blocked by tempo-
rary ambient conditions such as splashing
water, mist or fog. The blocked condition
may also be caused by objects such as ice,
frost or dirt obstructing the sonar sensors.
Action to take:
When the above conditions no longer exist,
the system will resume automatically.
5-146Starting and driving

∙ If the low tire pressure warning light illu-minates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage could
occur and may lead to an accident and
could result in serious personal injury.
Check the tire pressure for all four tires.
Adjust the tire pressure to the recom-
mended COLD tire pressure shown on
the Tire and Loading Information label to
turn the low tire pressure warning light
OFF. If the light still illuminates while
driving after adjusting the tire pressure,
a tire may be flat or the TPMS may be
malfunctioning. If you have a flat tire, re-
place it with a spare tire as soon as pos-
sible, If no tire is flat and all tires are
properly inflated, have the vehicle
checked. It is recommended that you visit
an INFINITI retailer for this service. ∙ When replacing a wheel without TPMS
such as the spare tire, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for these services.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ Do not inject any tire liquid or aerosol tire sealant into the tires, as this may cause a
malfunction of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to P
(Park).
4. Turn off the engine. 5. Raise the hood to warn other traffic and
to signal professional road assistance
personnel that you need assistance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
∙ Make sure the parking brake is securelyapplied and the Continuously Variable
Transmission (CVT) is shifted into P
(Park).
∙ Never change tires when the vehicle is on a slope, ice or slippery areas. This is
hazardous.
∙ Never change tires if oncoming traffic is close to your vehicle. Wait for profes-
sional road assistance.
6-4In case of emergency

∙ If the wheels are changed for any reason,always replace with wheels which have
the same off-set dimension. Wheels of a
different off-set could cause premature
tire wear, degrade vehicle handling char-
acteristics, affect the VDC system
and/or interference with the brake discs.
Such interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information on
wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical and
consumer information” section of this
manual.
∙ When replacing a wheel without the TPMS, such as the spare tire, the TPMS
will not function and the low tire pressure
warning light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for this service.
∙ Replacing tires with those not originally specified by INFINITI could affect the
proper operation of the TPMS.
∙ The TPMS sensor may be damaged if it is not handled correctly. Be careful when
handling the TPMS sensor. ∙ When replacing the TPMS sensor, the ID
registration may be required. It is recom-
mended that you visit an INFINITI re-
tailer for ID registration.
∙ Do not use a valve stem cap that is not specified by INFINITI. The valve stem cap
may become stuck.
∙ Be sure that the valve stem caps are cor- rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a malfunc-
tion or loss of pressure.
∙ Do not install a damaged or deformed wheel or tire even if it has been repaired.
Such wheels or tires could have structural
damage and could fail without warning.
∙ The use of retread tires is not recommended.
∙ For additional information regarding tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required. Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the wheels on the vehicle could lead to
mechanical damage.
∙ For additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Care of wheels
∙ Wash the wheels when washing the ve-
hicle to maintain their appearance.
∙ Clean the inner side of the wheels when the wheel is changed or the underside of
the vehicle is washed.
∙ Do not use abrasive cleaners when washing the wheels.
∙ Inspect wheel rims regularly for dents or corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
∙ INFINITI recommends waxing the road wheels to protect against road salt in
areas where it is used during winter.
