sharp curves.
∙ The system is designed to automati- cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction 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.

– 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 driving5-121

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 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 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 the indicator light
is on.
The VDC OFF switch is used to turn off the
VDC system. The
, RAB, and AEB with
Pedestrian Detection indicator lights illumi-
nate to indicate the VDC, RAB, and AEB with
Pedestrian Detection systems are off.
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM
5-122Starting and driving

ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls engine torque and four wheel
brake pressure. This will enhance ride com-
fort in effort to restrain uncomfortable up-
per body movement when passing over
undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
When the VDC OFF switch is used to turn off
the VDC system, the ARC is also turned off.
If the Chassis Control System Error warn-
ing message appears in the vehicle infor-
mation display, it may indicate that the ARC
is not functioning properly. Have the sys-
tem checked as soon as possible. It is rec-
ommended that you visit a NISSAN dealer
for this service.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating 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 ma-
neuvers. 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 col-
ors of the corner sonar indicator and
the distance guide lines in the
front/rear view indicate different dis-
tances 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 station-
ary objects to help avoid damaging
the vehicle.

FRONT AND REAR SONAR SYSTEM (if
so equipped)
5-126Starting and driving

∙ The system is not designed to preventcontact with small or moving objects.
Always move slowly. The system will
not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
∙ The system may not detect the fol- lowing objects: fluff y objects such as
snow, cloth, cotton, glass, wool, etc.,
and thin objects such as rope, wire
and chain, etc., or wedge-shaped
objects.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles 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 ob-
jects. If the sensors are covered, the
accuracy of the sonar function will be
diminished.
SYSTEM OPERATION
The system informs with a visual and au-
dible alert of front obstacles when the shif t
lever is in the D (Drive) position and both
front and rear obstacles when the shif t le-
ver is in the R (Reverse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds. While the vehicle is moving the audible alert
will stop af ter 3 seconds when an obstacle
is detected by only the corner sensor and
distance does not change. The audible
alert will also stop when the obstacle
moves away from the vehicle. At any time
the lef t side button of the steering wheel
(
buttons) is available to cancel the
audible alert.
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
blinking and turns red, and the tone
sounds continuously.

TIRE PRESSURE MONITORING
SYSTEM (TPMS)
This vehicle is equipped with 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 infor-
mation 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 activate only when the vehicle is driven
at speeds above 16 mph (25 km/h). For ad-
ditional information, refer to “Warning
lights, indicator lights and audible remind-
ers” in the “Instruments and controls” sec-
tion and “Tire Pressure Monitoring System
(TPMS)” in the “Starting and driving” section
of this manual.
WARNING
∙ Radio waves could adversely affectelectric medical equipment. Those
who use a pacemaker should contact
the electric medical equipment
manufacturer for the possible influ-
ences before use. ∙ If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull off
the road to a safe location and stop
the vehicle as soon as possible. Driv-
ing with under-inflated tires may per-
manently damage the tires and in-
crease the likelihood of tire failure.
Serious vehicle damage could occur
and may lead to an accident and could
result in serious personal injury.
Check the tire pressure for all four
tires. Adjust the tire pressure to the
recommended COLD tire pressure
shown on the Tire and Loading Infor-
mation label to turn the low tire pres-
sure warning light OFF. If the light still
illuminates while driving af ter adjust-
ing the tire pressure, a tire may be flat
or the TPMS may be malfunctioning. If
you have a flat tire, replace it with a
spare tire as soon as possible. If no tire
is flat and all tires are properly in-
flated, have the vehicle checked. It is
recommended that you visit a NISSAN
dealer for this service. ∙ When replacing a wheel without the
TPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately 1 minute. The light will re-
main on af ter 1 minute. Have your
tires replaced and/or TPMS system
reset as soon as possible. It is recom-
mended that you visit a NISSAN dealer
for these services.
∙ Replacing tires with those not origi- nally 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 pres-
sure sensors.
∙ If the light still comes on while driving af ter 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 recom-
mended that you visit a NISSAN dealer
for this service.
