2017 INFINITI QX60 power control system

Shift lock release
If the battery charge is low or discharged, the
shift lever may not be moved from the P (Park)
position even with the brake pedal depressed
and the shift lever button pushed. To move the
shift lever, perform the following procedure:1. Push the ignition switch to the OFF or LOCK position.
2. Apply the parking brake.
3. Remove the shift lock release cover using a suitable tool.
4. Push down the shift lock release using a suitable tool. 5. Push the shift lever button and move the shift
lever to the N (Neutral) position while hold-
ing down the shift lock release. The vehicle
may be moved to the desired location. Re-
place the removed shift lock release cover
after the operation.
If the shift lever cannot be moved out of the P
(Park) position, have the CVT system checked as
soon as possible. It is recommended that you visit
an INFINITI retailer for this service.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
High fluid temperature protection
mode
This transmission has a high fluid temperature
protection mode. If the fluid temperature be-
comes too high (for example, when climbing
steep grades in high temperatures with heavy
loads, such as when towing a trailer) , engine
power and, under some conditions, vehicle
speed will be decreased automatically to reduce
the chance of transmission damage. Vehicle
speed can be controlled with the accelerator
pedal, but the engine and vehicle speed may be
limited.
Fail-safe
When the fail-safe operation occurs, the CVT will
not be shifted into the selected driving position.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The Malfunction
Indicator Light (MIL) may come on to indi-
cate the fail-safe mode is activated. For
additional information, refer to “Malfunc-
tion Indicator Light (MIL)” in the “Instru-
ments and controls” section of this manual.
This will occur even if all electrical circuits
are functioning properly. In this case, place
the ignition switch in the OFF position and

warning” in this section.
The following items are controlled in the ICC
system:● When there are no vehicles traveling ahead,
the ICC system maintains the speed set by
the driver. The set speed range is between
approximately 20 and 90 mph (32 and
144 km/h).
● When there is a vehicle traveling ahead, the
ICC system adjusts the speed to maintain
the distance, selected by the driver, from the
vehicle ahead. If the vehicle ahead comes to
a stop, the vehicle decelerates to a standstill
within the limitations of the system. The sys-
tem will cancel once it judges a standstill
with a warning chime.
● When the vehicle traveling ahead has moved
out from its lane of travel, the ICC system
accelerates and maintains vehicle speed up
to the set speed.
The ICC 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 when approaching toll gates
or traffic congestion. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead, the
ICC system will adjust the speed to maintain the
distance, selected by the driver, from the vehicle
ahead. If the vehicle ahead changes lanes or exits
the freeway, the ICC system will accelerate and
maintain the speed up to the set speed. Pay
attention to the driving operation to maintain con-
trol of the vehicle as it accelerates to the set
speed.
Normally when controlling the distance to a ve-
hicle ahead, this system automatically acceler-
ates or decelerates your vehicle according to the
speed of the vehicle ahead. Depress the accel-
erator to properly accelerate your vehicle whenacceleration is required for a lane change. De-
press the brake pedal when deceleration is re-
quired to maintain a safe distance to the vehicle
ahead due to its sudden braking or if a vehicle
cuts in. Always stay alert when using the ICC
system.
ICC (Vehicle-to-vehicle distance
control) mode
In the vehicle-to-vehicle distance control mode,
the ICC system automatically maintains a se-
lected distance from the vehicle traveling in front
of you according to that vehicle’s speed (up to
the set speed) , or at the set speed when the road
ahead is clear.
The system is intended to enhance the operation
of the vehicle when following a vehicle traveling in
the same lane and direction.
If the radar sensor detects a slower moving ve-
hicle ahead, the system will reduce the vehicle
speed so that your vehicle follows the vehicle in
front at the selected distance.
The system automatically controls the throttle
and applies the brakes (up to approximately 40%
of vehicle braking power) if necessary. The de-
tection range of the sensor is approximately
650 ft (200 m) ahead.
SSD0254
5-78Starting and driving

The system is intended to assist the driver to
keep a following distance from the vehicle ahead
traveling in the same lane and direction.
The distance sensor is located behind the front
bumper
A. If the distance sensorAdetects a
slower moving vehicle ahead, the system will
reduce the vehicle speed to help assist the driver
to maintain a following distance.
The system automatically controls the throttle
and applies the brakes (up to 40% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 490 ft (150 m) ahead.
The distance sensor will not detect the following
objects.
● Stationary and slow moving vehicles
● Pedestrians or objects in the roadway
● Oncoming vehicles in the same lane The display is located between the speedometer
and tachometer.
1. DCA system switch indicator: Indicates that the dynamic driver assistance
switch is on. 2. Vehicle ahead detection indicator:
Indicates whether it detects a vehicle in front
of you.
WARNING
The DCA system automatically deceler-
ates your vehicle to help assist the driver
to maintain a following distance from the
vehicle ahead. Manually brake when de-
celeration is required to maintain a safe
distance upon sudden braking by the ve-
hicle ahead or when a vehicle suddenly
appears in front of you. Always stay alert
when using the DCA system.
DCA Indicators
LSD2068LIC2889
Starting and driving5-97

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.

WARNING
●If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
● When the power steering warning light
illuminates with the engine running,
there will be no power assist for the
steering. You will still have control of
the vehicle, but the steering will be
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit an INFINITI re-
tailer for this service.
The power steering system is designed to pro-
vide power assist while driving to operate the
steering wheel with light force.
When the steering wheel is operated repeatedly
or continuously while parking or driving at a very
low speed, the power assist for the steering
wheel will be reduced. This is to prevent over-
heating of the power steering system and protect
it from getting damaged. While the power assist
is reduced, steering wheel operation will become
heavy. When the temperature of the power steer-
ing system goes down, the power assist level will
return to normal. Avoid repeating such steering wheel operations that could cause the power
steering system to overheat.
You may hear a sound when the steering wheel is
operated quickly. However, this is not a malfunc-
tion.
If the electric power steering warning light illumi-
nates while the engine is running, it may indicate
the power steering system is not functioning
properly and may need servicing. Have the power
steering system checked. It is recommended that
you visit an INFINITI retailer for this service.
When the electric power steering warning light
illuminates with the engine running, there will be
no power assist for the steering, but you will still
have control of the vehicle. At this time, greater
steering effort is required to operate the steering
wheel, especially in sharp turns and at low
speeds.
For additional information, refer to “Power steer-
ing warning light” in the “Instruments and con-
trols” section of this manual.
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake pads faster, and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.

BRAKE SYSTEM
5-132Starting and driving

WARNING
●While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
● If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
Parking brake break-in
Break in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or rotors are
replaced, in order to assure the best brake per-
formance. This procedure is described in the INFINITI Ser-
vice Manual. It is recommended that you visit an
INFINITI retailer for this service.
ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
●
The ABS is a sophisticated device, but it
cannot prevent accidents resulting from
careless or dangerous driving tech-
niques. It can help maintain vehicle con-
trol during braking on slippery surfaces.
Remember that stopping distances on
slippery surfaces will be longer than on
normal surfaces even with ABS. Stop-
ping distances may also be longer on
rough, gravel or snow covered roads, or
if you are using tire chains. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
● 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 spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. For additional in-
formation, refer to “Tire and Loading
Information label” in the “Technical
and consumer information” section
of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself” section of this manual.
The ABS controls the brakes so the wheels do
not lock during hard braking or when braking on
slippery surfaces. The system detects the rota-
tion speed at each wheel and varies the brake
fluid pressure to prevent each wheel from locking
and sliding. By preventing each wheel from lock-
ing, the system helps the driver maintain steering
control and helps to minimize swerving and spin-
ning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
Starting and driving5-133

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 malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument 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-
er’s 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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-134Starting and driving

When the VDC system operates, theindi-
cator 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 indicates that the
VDC system is working properly.
● Adjust your speed and driving to the road
conditions.
For additional information, refer to “Slip indicator
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 instru-
ment panel. The VDC system automatically turns
off when these indicator lights are on.
The VDC OFF switch is used to turn off the VDC
system. The
indicator illuminates to indi-
cate the VDC system is off.
When the VDC 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 flashes if this occurs. All other VDC
functions are off and the
indicator 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 feature
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 malfunction.
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 tech-
niques. Reduce vehicle speed and be
especially careful when driving and cor-
nering on slippery surfaces and always
drive carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not INFINITI
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or both the
andindica-
tor lights may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extremely
deteriorated, the VDC system may not
operate properly and both the
and theindicator lights may
illuminate.
● If engine control related parts are not
INFINITI recommended or are extremely
deteriorated, both the
andindicator lights may illuminate.
