2018 INFINITI Q70-HYBRID ABS

5-122Starting and driving
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 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).
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
properly. However, the pulsation may indi-
cate that road conditions are hazardous and
extra care is required while driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving
conditions, 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 or
mortor output to reduce drive wheel slip
based on vehicle speed (traction control
function).
. Controls brake pressure at individual
wheels and engine or motor output to
help the driver maintain control of the
vehicle in the following 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
maintain control of the vehicle, but it cannot
prevent loss of vehicle control in all driving
situations.
When the VDC system operates, the VDC
warning 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.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system automa-
tically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator light
illuminates to indicate 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 VDC warning light
flashes if
this occurs. All other VDC functions are off,
except for rise-up and build-up and brake
force distribution, and the VDC warning
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.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-17) and “Vehicle Dynamic
VEHICLE DYNAMIC CONTROL
(VDC) SYSTEM

Control (VDC) off indicator light” (P.2-20).
The computer has a built-in diagnostic
feature that tests the system each time you
start the INFINITI Direct Response Hybrid
®
System 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 mal-
function.
ACTIVE TRACE CONTROL (if so
equipped)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and individually controls the brak-
ing to each of the four wheels to help
smooth vehicle response.
When the INFINITI Drive Mode Selector is
set to the “SPORT” mode, the amount of
brake control provided by active trace con-
trol is reduced.
When the VDC OFF switch is used to turn
off the VDC system, the active trace control
system is also turned off.
If the active trace control is not functioning
properly, the Forward Emergency Braking
(FEB) system warning light illuminates in the
instrument panel.
RISE-UP AND BUILD-UP
The system gradually adjusts braking power
during normal braking to help provide an
enhanced brake feel.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the four wheels depending
on the radius of the turn.
WARNING
.The VDC system is designed to help
the driver maintain stability 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.
. The active trace control (if so
equipped), rise-up and build-up and
brake force distribution systems may
not be effective depending on the
driving condition. Always drive care-
fully and attentively.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as shock absorbers, struts, springs, sta-
bilizer 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 performance, and
the VDC warning light
may
illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
INFINITI recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are not
INFINITI recommended or are extre-
mely deteriorated, the VDC warning
light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked cor-
ners, the VDC system may not oper-
ate properly and the VDC warning
light
may illuminate. Do not drive
on these types of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.
