AEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the AEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The AEB system cannot detect all ve-
hicles under all conditions.
∙ The radar sensor does not detect the following objects:
– Pedestrians, animals or obstacles in the roadway.
– Oncoming vehicles.
– Crossing vehicles.
∙ The radar sensor has some perfor- mance limitations. If a stationary ve-
hicle is in the vehicle’s path, the AEB
system will not function when the ve-
hicle is driven at speeds over approxi-
mately 50 mph (80 km/h). ∙ The radar sensor may not detect a ve-
hicle ahead in the following
conditions:
– Dirt, ice, snow or other material covering the radar sensor.
– Interference by other radar sources.
– Snow or road spray from traveling vehicles.
– If the vehicle ahead is narrow (e.g., motorcycle).
– When driving on a steep downhill slope or roads with sharp curves.
∙ In some road or traffic conditions, the AEB system may unexpectedly apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
∙ Braking distances increase on slip- pery surfaces.

– When replacing tires, install thespecified 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 ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” 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 rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent 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
prevent 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) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov
e3-6mph(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 applies and releases hydraulic pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous 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 driving5-55

WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’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 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 func-
tion).
∙ Controls brake pressure at individual wheels and engine output to help the
driver maintain control of the vehicle in
the following conditions:
– Understeer (vehicle tends to not fol- low the steered path despite in-
creased 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 can-
not prevent loss of vehicle control in all driv-
ing situations. When the VDC system operates, theindicator 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 indi-
cates that the VDC system is working
properly.
∙ Adjust your speed and driving to the road conditions.
For additional information, refer to “Slip in-
dicator light” and ”Vehicle Dynamic Control
(VDC) OFF indicator light” in the ”Instru-
ments and controls” section of this manual.
If a malfunction occurs in the system,
the
indicator light comes on in the
instrument panel. The VDC system auto-
matically turns off when these indicator
lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light and
the Automatic Emergency Braking (AEB)
system warning light illuminate to indicate
the VDC system is off.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-56Starting and driving

The chassis control is an electric control
module that includes the following func-
tions:∙ Intelligent Trace Control
∙ Intelligent Engine Brake
∙ Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response. The I–TC can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Chassis Control” page. For addi-
tional information, refer to “Vehicle infor-
mation display” in the “Instruments and
controls” section of this manual.
When the Vehicle Dynamic Control (VDC)
OFF switch is used to turn off the VDC sys-
tem, the I–TC is also turned off.
When the I–TC is operated and the Chassis
Control mode is selected in the vehicle in-
formation display, the I–TC graphics are
shown in the vehicle information display.
For additional information, refer to “Vehicleinformation display” in the “Instruments
and controls” section of this manual.
WARNING
The I–TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the I–TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I–TC is operating properly.
Even if the I–TC is set to OFF, some func-
tions will remain on to assist the driver (for
example, avoidance scenes).
INTELLIGENT ENGINE BRAKE (I-EB)
The I-EB function adds subtle deceleration
by controlling the Continuously Variable
Transmission gear ratio, depending on the
cornering condition calculated from driv-
er’s steering input and plural sensors. This
benefit is for easier traceability and less
workload of adjusting speed with braking
at corners.
The I-EB also adds subtle deceleration with
gear ratio control according to driver’s
brake pedal operation.
