2023 INFINITI QX55 instrument panel

Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or rotors are replaced, in order to
assure the best brake performance.
This procedure is described in the INFINITI
Service 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 main-
tain a safe distance from the vehicle in
front of you. Ultimately, the driver is re-
sponsible 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, see “Tire and Loading In-
formation label” (P. 8-29).
– For additional information, see
“Wheels and tires” (P. 8-27).
The 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 the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to pre- vent 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 Anti-lock Braking System (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 op-
erates 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.
5-140Starting and driving

Normal operation
The Anti-lock Braking System (ABS) operates
at speeds above3-6mph(5-10km/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 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.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional 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. 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 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 fol-
lowing 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
situations.
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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
Starting and driving5-141

• You may feel a pulsation in the brake pedaland 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, see “Slip indicator
light” (P. 2-17) and ”Vehicle Dynamic Control
(VDC) OFF indicator light” (P. 2-17).
If a malfunction occurs in the system, the
andindicator lights come on in the
instrument panel. The VDC system automati-
cally turns off when these indicator lights are
on.
The lower display is used to turn off the VDC
system. When the VDC system is turned off,
the
indicator light, the RAB system
warning light, and the FEB with Pedestrian
Detection system warning light illuminate to
indicate the VDC, FEB with Pedestrian De-
tection, and RAB systems are off.
When the lower display is used to turn off the
system, the VDC system still operates to pre-
vent one drive wheel from slipping by trans-
ferring 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
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 es-
pecially careful when driving and corner-
ing 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 ex-
tremely deteriorated, the VDC system
may not operate properly. This could ad-
versely affect vehicle handling perfor-
mance, and the
indicator light may
flash or both theandindicator
lights may illuminate.
• If brake related parts such as brake pads,
rotors and calipers are not INFINITI rec-
ommended or are extremely deterio-
rated, 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.
• When driving on extremely inclined sur-
faces such as higher banked corners, the
VDC system may not operate properly
and the
indicator light may flash or
both theandindicator lights
may illuminate. Do not drive on these
types of roads.
