RAB SYSTEM OPERATION
When the shift lever is in the R (Reverse)
position and the vehicle speed is less than
approximately 9 MPH (15 km/h), the RAB
system operates.
If a risk of a collision with an obstacle is
detected when your vehicle is backing up,
the RAB system warning indicator will
flash in the vehicle information display, a
red frame will appear in the center display
(models with the Intelligent Around
View
Monitor system), and the system
will chime three times. The system will
then automatically apply the brakes. After
the automatic brake application, the dri-
ver must depress the brake pedal to
maintain brake pressure.
NOTE:
. The stop lights of the vehicle come
on when braking is performed by
the RAB system.
. When the brakes operate, a noise
may be heard. This is not a malfunc-
tion.
TURNING THE RAB SYSTEM ON/OFF
Perform the following steps to turn the
RAB system ON or OFF.
Starting and driving5-133

5-136Starting and driving
— The vehicle is driven in badweather (rain, fog, snow, etc.).
— The vehicle is driven on a steep hill.
— The vehicle’s posture is chan- ged (e.g., when driving over a
bump).
— The vehicle is driven on a slippery road.
— The vehicle is turned sharply by turning the steering wheel
fully.
— Snow chains are used.
— Wheels or tires other than NISSAN recommended are
used.
— The brakes are cold at low ambient temperatures or im-
mediately after driving has
started.
— The braking force becomes poor due to wet brakes after
driving through a puddle or
washing the vehicle.
. Turn the RAB system off in the
following conditions to prevent
the occurrence of an unexpected
accident resulting from sudden
system operation: — The vehicle is towed.
— The vehicle is carried on a
flatbed truck.
— The vehicle is on the chassis dynamometer.
— The vehicle drives on an un- even road surface.
— Suspension parts other than those designated as genuine
parts are used. (If the vehicle
height or the vehicle body
inclination is changed, the
system may not detect an
obstacle correctly.)
. Excessive noise (e.g., audio sys-
tem volume, an open vehicle win-
dow) will interfere with the chime
sound, and it may not be heard.SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the
“Malfunction” warning message will ap-
pear in the vehicle information display.
Action to take
If the warning light illuminates, park the
vehicle in a safe location, turn the engine
off, and restart the engine. If the warning
light continues to illuminate, have the
RAB system checked. It is recommended
that you visit a NISSAN dealer for this
service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.

BRAKING PRECAUTIONS
The brake system has two separate
hydraulic circuits. If one circuit malfunc-
tions, you will still have braking at two
wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you
can stop the vehicle by depressing the
brake pedal. However, greater foot pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake
pedal while driving. This will cause over-
heating of the brakes, wearing out the
brake pads faster and reduce gas mile-
age.
To help reduce brake wear and to prevent
the brakes from overheating, reduce
speed and downshift to a lower gear
before going down a slope or long grade.
Overheated brakes may reduce braking
performance and could result in loss of
vehicle control.
WARNING
.While driving on a slippery sur-
face, be careful when braking,
accelerating or downshifting.
Abrupt braking or accelerating
could cause the wheels to skid
and result in an accident.
. If the engine is not running or is
turned off while driving, the
power assist for the brakes will
not work. Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet.
As a result, your braking distance will be
longer and the vehicle may pull to one
side during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake
pedal to heat-up the brakes. Do this until
the brakes return to normal. Avoid driving
the vehicle at high speeds until the brakes
function correctly.
Parking brake break-in
Break in the parking brake shoes when-
ever the stopping effect of the parking
brake is weakened or whenever the
parking brake shoes and/or drums/ro-
tors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual. It is recommended you
visit a NISSAN dealer for this service.

BRAKE SYSTEM

5-146Starting and 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.
WARNING
The Brake Assist is only an aid to
assist braking operation and is not a
collision warning or avoidance de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System
(ABS) is a sophisticated device,
but it cannot prevent accidents
resulting from careless or dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire
chains. Always maintain a safe
distance from the vehicle in front
of you. Ultimately, the driver is
responsible for safety.
. 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 Informa-
tion label. See “Tire and Load-
ing Information label” (P.10-
10) of this manual.
— For detailed information, see “Wheels and tires” (P.8-29) of
this manual.
The Anti-lock Braking System (ABS) con-
trols 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 pre- venting 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 ABS 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 ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-
BRAKE ASSIST

tion, 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
vehicle checked. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 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 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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
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 con-
trol function).
. 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
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
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.
When the VDC system operates, the VDC
warning 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 indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate 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 VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
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.
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-16) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).

VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

5-152Starting and driving
WARNING
.Never rely solely on the hill start
assist system to prevent the ve-
hicle from moving backward on a
hill. Always drive carefully and
attentively. Depress the brake
pedal when the vehicle is stopped
on a steep hill. Be especially care-
ful when stopped on a hill on
frozen or muddy roads. Failure
to prevent the vehicle from rolling
backwards may result in a loss of
control of the vehicle and possi-
ble serious injury or death.
. The hill start assist system is not
designed 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 prevent the vehicle from roll-
ing backwards on a hill under all
load or road conditions. 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 personal injury.
The hill start assist system automatically
keeps the brakes applied to help prevent
the vehicle from rolling backwards in the
time it takes the driver to release the
brake pedal and apply the accelerator
when the vehicle is stopped on a hill.
The hill start assist system will operate
automatically under the following condi-
tions:
. The transmission is shifted to a for-
ward 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 vehicle 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 transmission is shifted
to the N (Neutral) or P (Park) position (CVT
models) or on a flat and level road.
When the Vehicle Dynamic Control (VDC)
warning light illuminates in the meter, the
hill start assist system will not operate.
(See “Vehicle Dynamic Control (VDC)
warning light” (P.2-16).)

The RSS sounds a tone to inform the
driver of obstacles near the rear bumper.
When the “Display” key is on, the sonar
view will automatically appear in the
touchscreen display. An additional view
of the sonar status will appear in the
vehicle information display for reference.
WARNING
. The RSS is a convenience but it is
not a substitute for proper park-
ing.
. The driver is always responsible

other maneuvers. Always look
around and check that it is safe
to do so before parking.
. Read and understand the limita-
tions of the RSS as contained in
this section. The colors of the
sonar indicator and the distance
guide lines in the rear view in-
dicate 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 perfor-
mance or a false activation.
. The RSS is designed as an aid to
the driver in detecting large sta-
tionary objects to help avoid da-
maging the vehicle.
. The RSS is not designed to pre-
vent contact with small or mov-
ing 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 RSS may not detect the
following objects: fluffy objects
such as snow, cloth, cotton, glass, wool, etc.; 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 vehi-
cle window) will interfere with the
tone and it may not be heard.
. Keep the sonar sensors (located
on the rear bumper fascia) free
from snow, ice and large accu-
mulations of dirt. Do not clean the
sensors with sharp objects. If the
sensors are covered, the accuracy
of the sonar function will be
diminished.
