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-
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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-136Starting and driving
Page 490 of 607

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.

●When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
both the
andindicator
lights 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
indicator may flash or
both the
andindicator
lights may illuminate. This is not a mal-
function. Restart the engine after driv-
ing onto a stable surface.
● If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the
indicator may flash or both
the
andindicator lights may
illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.
ACTIVE TRACE CONTROL (if so
equipped)
This system senses driving based on the driver’s
steering and acceleration/braking patterns, and
controls brake pressure at individual wheels to
help smooth vehicle response.
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 prop-
erly, the FEB OFF indicator light illuminates in the
instrument panel.
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 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,

WARNING
● Never rely solely on the hill start assist
system to prevent the vehicle from mov-
ing backward on a hill. Always drive
carefully and attentively. Depress the
brake pedal when the vehicle is stopped
on a steep hill. Be especially careful
when stopped on a hill on frozen or
muddy roads. Failure to prevent the ve-
hicle from rolling backwards may result
in a loss of control of the vehicle and
possible serious injury or death.
● The hill start assist system is not de-
signed to hold the vehicle at a standstill
on a hill. Depress the brake pedal when
the vehicle is stopped on a steep hill.
Failure to do so may cause the vehicle
to roll backwards and may result in a
collision or serious personal injury.
● The hill start assist system may not pre-
vent the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the vehicle
from rolling backwards. Failure to do so
may result in a collision or serious per-
sonal injury. When the vehicle is stopped on a hill, the hill start
assist system automatically keeps the brakes ap-
plied 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 automati-
cally 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 seconds the ve-
hicle will begin to roll back and the hill start
assist system will stop operating completely.
The hill start assist system will not operate when
the shift lever is placed in the N (Neutral) or P
(Park) position or on a flat and level road.

The sonar (parking sensor) system sounds a tone
to inform the driver of obstacles near the bumper.
When the “DISPLAY” key is ON, the sonar view
will automatically appear in the meter.
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
designed to prevent contact with ve-
hicles 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
objects to help avoid damaging the
vehicle.
If your vehicle sustains damage to the bumper
fascia, leaving it misaligned or bent, the sensing
zone may be altered causing inaccurate mea-
surement 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 sensors are covered, the accuracy of
the sonar function will be diminished.
SYSTEM OPERATION
The system informs with a visual and audible
signal of front obstacles when the shift lever is in
the D (Drive) position and both front and rear
obstacles when the shift lever is in the R (Re-
verse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop after 3 seconds
when an obstacle is detected by only the corner
sensor and the distance does not change. The
tone will stop when the obstacle get away from
the vehicle.

When the object is detected, the indicator
(green) appears and blinks and the tone sounds
intermittently. When the vehicle moves closer to
the object, the color of the indicator turns yellow
and the rate of the blinking increase. When the
vehicle is very close to the object, the indicator
stops blinking and turns red, and the tone sounds
continuously.When the corner of the vehicle moves closer to
an object, the corner sonar indicators
Aap-
pears. When the center of the vehicle moves
close to an object, the center sonar (if so
equipped) indicator
Bappears. The system indicators
