2016 INFINITI QX60 HYBRID brake sensor

The following are some conditions in which the
sensor cannot detect the signals:● When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
detection
● When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area around the distance sensor is cov-
ered with dirt or is obstructed, the system will
automatically cancel. If the front bumper area of
the distance sensor is covered with ice, a trans-
parent or translucent vinyl bag, etc., the DCA
system may not detect them. In these instances,
the vehicle-to-vehicle distance control mode may
not cancel and may not be able to maintain the
selected following distance from the vehicle
ahead. Be sure to check and clean the front
bumper area around the distance sensor regu-
larly.
The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop, the vehicle decelerates to a standstill. However,
the DCA system can only apply up to 40% of the
vehicle’s total braking power. If a vehicle moves
into the traveling lane ahead or if a vehicle travel-
ing ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
DCA system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA system
will sound a warning chime and blink the system
display to notify the driver to take necessary
action.
For additional information, refer to “Approach
warning” in this section.
This system only brakes and moves the accelera-
tor pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead.
Starting and driving5-101

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may cause
the system to work inappropriately.
The detection of vehicles may also be affected by
vehicle operation (steering maneuver or traveling
position in the lane, etc.) or vehicle condition.If
this occurs, the system may warn you by
blinking the system indicator and sounding
the chime unexpectedly. You will have to
manually control the proper distance away
from the vehicle traveling ahead.Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:
● The chime sounds.
● The vehicle ahead detection indicator blinks. The warning chime may not sound in some cases
when there is a short distance between vehicles.
Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

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 hybrid
system 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 pulsa-
tion 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 instru-
ment panel. The brake system then operates
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 that you visit an
INFINITI retailer for this service.
Normal operation
The ABS operates at speeds above3-6mph(5
- 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 ap-
plies 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 pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all times.
The VDC system uses various sensors to monitor
driver inputs and vehicle motion. Under certain
driving conditions, the VDC system helps to per-
form 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.

●Read and understand the limitations of
the sonar system as contained in this
section. 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 system; this may include reduced
performance or a false activation.
● The system is not designed to prevent
contact with small or moving objects.
Always move slowly. The system will
not detect small objects below the bum-
per or on the ground.
● The system may not detect the follow-
ing objects: Fluffy objects such as
snow, cloth, cotton, glass-wool, etc.
Thin objects 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 conditions no
longer exist.
The sonar sensors may be blocked by temporary
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.
SYSTEM MAINTENANCE
The sonar sensors are located on the front and
rear bumpers. Always keep the area near the
sonar sensors clean.
The sonar sensors may be blocked by temporary
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.
Check for and remove objects obstructing the
area around the sonar sensors.
