Listed below are the system limitations for
the PFCW system. Failure to operate the
vehicle in accordance with these system
limitations could result in serious injury or
death.
●The PFCW 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
● (Illustration A) The PFCW system does
not function when a vehicle ahead is a
narrow vehicle, such as a motorcycle.
● The radar sensor may not detect a ve-
hicle ahead in the following conditions:
– Snow or heavy rain
– Dirt, ice, snow or other material cov- ering the radar sensor.
– Interference by other radar sources. – Snow or road spray from traveling
vehicles.
– Driving in a tunnel
– (Illustration B) When the vehicle ahead is being towed.
– (Illustration C) When the distance to the vehicle ahead is too close, the
beam of the radar sensor is
obstructed.

●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.SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interference
from another radar source, making it impossible
to detect a vehicle ahead, the PFCW system is
automatically turned off.
The FEB system warning light (orange) will illu-
minate. Action to take
When the above conditions no longer exist, the
PFCW system will resume automatically.
Condition B
When the sensor area of the front bumper is
covered with dirt or is obstructed, making it im-
possible to detect a vehicle ahead, the PFCW
system is automatically turned off.
The FEB system warning light (orange) will illu-
minate and the “Unavailable: Front Radar Ob-
struction” warning message will appear in the
vehicle information display.

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 a
NISSAN dealer 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
Starting and driving5-81

The Integrated Dynamics-control Module is an
electric control module that includes the follow-
ing functions:● Active Trace Control
● Active Engine Brake
● Active Ride Control
ACTIVE TRACE CONTROL
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 Active Trace Control can be set to ON (en-
abled) or OFF (disabled) through the vehicle
information display “Settings” page. For addi-
tional information, refer to “Vehicle information
display” in the “Instruments and controls” section
of this manual.
When the VDC OFF switch is used to turn off the
VDC system, the Active Trace Control is also
turned off.
If the Integrated Dynamics-control Module warn-
ing message appears in the vehicle information
display, it may indicate that the Active Trace Con-
trol is not functioning properly. Have the system
checked as soon as possible. It is recommended
that you visit a NISSAN dealer for this service.
WARNING
The Active Trace Control may not be effec-
tive depending on the driving condition.
Always 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.
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 CVT gear ratio, de-
pending on the cornering condition calculated
from driver’s steering input and plural sensors.
This benefit is for easier traceability and less
workload of adjusting speed with braking at cor-
ners.
The Active Engine Brake also enhances braking
feel by adding subtle deceleration with CVT gear
ratio control according to driver’s brake pedal
operation.
The Active Engine Brake can be set to ON (en-
abled) or OFF (disabled) through the vehicle
information display “Settings” page. For addi- tional information, refer to “Vehicle information
display” in the “Instruments and controls” section
of this manual.
If the Integrated Dynamics-control Module warn-
ing message appears in the vehicle information
display, it may indicate that the Active Engine
Brake is not functioning properly. Have the sys-
tem checked as soon as possible. It is recom-
mended that you visit a NISSAN dealer for this
service.
WARNING
The Active Engine Brake may not be effec-
tive depending on driving conditions. Al-
ways drive carefully and attentively.
When the Active Engine Brake is operating, the
needle of the tachometer will rise up and you may
hear an engine noise. This is normal and indicates
that the active engine brake is operating properly.
ACTIVE RIDE CONTROL
This system senses upper body motion (based
on wheel speed information) and controls engine
torque and four wheel brake pressure. This will
enhance ride comfort in effort to restrain uncom-
fortable upper body movement when passing
over undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
INTEGRATED DYNAMICS-CONTROL
MODULE (if so equipped)
5-84Starting and driving

When the VDC OFF switch is used to turn off the
VDC system, the Active Ride Control is also
turned off.
If the Integrated Dynamics-control Module warn-
ing message appears in the vehicle information
display, it may indicate that the Active Ride Con-
trol is not functioning properly. Have the system
checked as soon as possible. It is recommended
that you visit a NISSAN dealer for this service.
When the Active Ride Control is operating, you
may hear noise and sense slight deceleration.
This is normal and indicates that the Active Ride
Control is operating properly.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
●The sonar (parking sensor) system is a
convenience but it is not a substitute for
proper parking.
● 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. ●
Read and understand the limitations of
the sonar (parking sensor) system as
contained in this section. The colors of
the corner sonar indicator and the dis-
tance guide lines in the front/rear view
indicate different distances to the
object.
● Inclement weather or ultrasonic
sources such as an automatic car wash,
a truck’s compressed-air brakes or a
pneumatic drill may affect the function
of the system; this may include reduced
performance or a false activation.
● This function is designed as an aid to
the driver in detecting large stationary
objects to help avoid damaging the
vehicle.
● The system is not designed to prevent
contact with small or moving objects.
Always move slowly. The system will
not detect small objects below the bum-
per, and may not detect objects close to
the bumper or on the ground.
● The system may not detect the follow-
ing objects: Fluffy objects such as
snow, cloth, cotton, glass, wool, etc.,
Thin objects such as rope, wire and
chain, etc., or wedge-shaped objects.

FRONT AND REAR SONAR SYSTEM
(if so equipped)
Starting and driving5-85

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 alarms.
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 fascia) 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 alert
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. Sonar Operation Table

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 indicator
Aappears.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with the TPMS. It moni-
tors tire pressure of all tires except the spare.
When the low tire pressure warning light is lit and
the “Tire Pressure Low-Add Air” warning appears
in the vehicle information display, one or more of
your tires is significantly under-inflated. If the
vehicle is being driven with low tire pressure, the
TPMS will activate and warn you of it by the low
tire pressure warning light. This system will acti-
vate only when the vehicle is driven at speeds
above 16 mph (25 km/h). For additional informa-
tion, refer to “Warning lights, indicator lights and
audible reminders” in the “Instruments and con-
trols” section and “Tire Pressure Monitoring Sys-
tem (TPMS)” in the “Starting and driving” section
of this manual.
WARNING
●Radio waves could adversely affect
electric medical equipment. Those who
use a pacemaker should contact the
electric medical equipment manufac-
turer for the possible influences before
use. ●
If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road
to a safe location and stop the vehicle
as soon as possible. Driving with under-
inflated tires may permanently damage
the tires and increase the likelihood of
tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal in-
jury. Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Informa-
tion label to turn the low tire pressure
warning light OFF. If you have a flat tire,
replace it with a spare tire as soon as
possible.
● Since the spare tire is not equipped with
the TPMS, when a spare tire is mounted
or a wheel is replaced, tire pressure will
not be indicated, the TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you
visit a NISSAN dealer for these services. ●
Replacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
● If the light still comes on while driving
after adjusting the tire pressure, a tire
may be flat or the TPMS may be mal-
functioning. If you have a flat tire, re-
place it with a spare tire as soon as
possible. If no tire is flat and all tires are
properly inflated, it is recommended
that you visit a NISSAN dealer for this
service.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to P (Park) .
FLAT TIRE
In case of emergency6-3

●Do not apply wheel cleaners to the
wheels when they are hot. The wheel
temperature should be the same as am-
bient temperature.
● Rinse the wheel to completely remove
the cleaner within 15 minutes after the
cleaner is applied.
CHROME PARTS
Clean all chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
TIRE DRESSINGS
NISSAN does not recommend the use of tire
dressings. Tire manufacturers apply a coating to
the tires to help reduce discoloration of the rub-
ber. If a tire dressing is applied to the tires, it may
react with the coating and form a compound. This
compound may come off the tire while driving and
stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
● Use a water-based tire dressing. The coat-
ing on the tire dissolves more easily than
with an oil-based tire dressing. ●
Apply a light coat of tire dressing to help
prevent it from entering the tire
tread/grooves (where it would be difficult to
remove) .
● Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is com-
pletely removed from the tire tread/grooves.
● Allow the tire dressing to dry as recom-
mended by the tire dressing manufacturer. Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather (if so equipped) surfaces with a clean,
soft cloth dampened in mild soap solution, then
wipe clean with a dry, soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather (if so
equipped) .
Before using any fabric protector, read the manu-
facturer’s recommendations. Some fabric pro-
tectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can dam-
age the seat or occupant classification
sensor. This can also affect the operation
of the air bag system and result in serious
personal injury.
CLEANING INTERIOR
7-4Appearance and care

CAUTION
●Do not ground accessories directly to
the battery terminal. Doing so will by-
pass the variable voltage control sys-
tem and the vehicle battery may not
charge completely.
● Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
Your vehicle is equipped with a variable voltage
control system. This system measures the
amount of electrical discharge from the battery
and controls voltage generated by the generator. The current sensor
Ais located near the battery
along the negative battery cable. If you add elec-
trical accessories to your vehicle, be sure to
ground them to a suitable body ground such as
the frame or engine block area.
