–(Illustration C) When the distance to
the vehicle ahead is too close, the
beam of the radar sensor is
obstructed.
– (Illustration D) When driving on a
steep downhill slope or roads with
sharp curves.
• The system is designed to automatically
check the sensor’s functionality, within
certain limitations. The system may not
detect some forms of obstruction of the
sensor area such as ice, snow, stickers,
etc. In these cases, the system may not
be able to warn the driver properly. Be
sure that you check, clean and clear the
sensor area regularly.
• Excessive noise will interfere with the
warning chime sound, and the chime may
not be heard.

•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.
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.
Starting and driving5-139

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. • 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, see “Slip indicator
light” (P. 2-16) 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.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-140Starting and driving

When the Active Trace Control is operated
and the “Chassis Control” mode is selected in
the vehicle information display, the Active
Trace Control graphics are shown in the ve-
hicle information display.
If the chassis control warning message ap-
pears in the vehicle information display, it
may indicate that the Active Trace Control is
not functioning properly. Have the system
checked as soon as possible by an INFINITI
retailer.WARNING
The Active Trace Control may not be effec-
tive depending on the driving condition. Al-
ways drive carefully and attentively.
When the Active Trace Control is operating,
you may feel a pulsation in the brake pedal
and hear a noise. This is normal and indicates
that the Active Trace Control is operating
properly.
You may also feel deceleration when the Ac-
tive Trace Control is operating. However, this
is not a malfunction. Even if the Active Trace Control is set to OFF,
some functions will remain on to assist the
driver (for example: avoidance scenes).
ACTIVE ENGINE BRAKE
The Active Engine Brake function adds subtle
deceleration by controlling Continuously
Variable Transmission (CVT) gear ratio, de-
pending on the cornering condition calcu-
lated from the driver's steering input and plu-
ral sensors. This benefit is for easier
traceability and less workload of adjusting
speed with braking at corners.
The Active Engine Brake also enhances brak-
ing feel by adding subtle deceleration with
CVT gear ratio control according to the driv-
er's brake pedal operation
The Active Engine Brake can be set to on
(enabled) or off (disabled) through the lower
display “Drive Mode Selector” menu option.

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
(Reverse) 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 sec-
onds 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 increases. When the vehicle is very
close to the object, the indicator stops blink-
ing and turns red, and the tone sounds
continuously.
