RAB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the RAB system. Failure to follow the
warnings and instructions for proper
use of the RAB system could result in
serious injury or death.
•
When the vehicle approaches an ob-
stacle while the accelerator or brake
pedal is depressed, the function may
not operate or the start of operation
may be delayed. The RAB system may
not operate or may not perform suffi-
ciently due to vehicle conditions, driv-
ing conditions, the traffic environment,
the weather, road surface conditions,
etc. Do not wait for the system to oper-
ate. Operate the brake pedal by your-
self as soon as necessary.
• If it is necessary to override RAB op-
eration, strongly press the accelera-
tor pedal.
•
Always check your surroundings and
turn to check what is behind you be-
fore and while backing up. The RAB
system detects stationary objects be-
hind the vehicle. The RAB system does
not detect the following objects:
– Moving objects –
Low objects
– Narrow objects
– Wedge-shaped objects
– Objects close to the bumper (less
than approximately 1 f t [30 cm])
– Objects that suddenly appear
– Thin objects such as rope, wire,
chain, etc.
• The RAB system may not operate for
the following obstacles:
– Obstacles located high off the
ground
– Obstacles in a position offset from
your vehicle
– Obstacles, such as spongy materi-
als or snow, that have sof t outer
surfaces and can easily absorb a
sound wave
• The RAB system may not operate in
the following conditions:
– There is rain, snow, ice, dirt, etc.,
attached to the sonar sensors.
– A loud sound is heard in the area
around the vehicle.
– The surface of the obstacle is di-
agonal to the rear of the vehicle. •
The RAB system may unintentionally
operate in the following conditions:
– There is overgrown grass in the
area around the vehicle.
– There is a structure (e.g., a wall, toll
gate equipment, a narrow tunnel,
a parking lot gate) near the side of
the vehicle.
–
There are bumps, protrusions, or manhole covers on the road surface.
– The vehicle drives through a
draped flag or a curtain.
– There is an accumulation of snow
or ice behind the vehicle.
– An ultrasonic wave source, such as
another vehicle’s sonar, is near
the vehicle.
•
Once the automatic brake control oper-
ates, it does not operate again if the
vehicle approaches the same obstacle.
• The automatic brake control can only
operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
• In the following situations, the RAB
system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad
weather (rain, fog, snow, etc.).
Starting and driving5-87

–The vehicle is driven on a steep
hill.
– The vehicle’s posture is changed
(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 ambi-
ent temperatures or immediately
af ter driving has started.
–
The braking force becomes poor due to wet brakes af ter 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 uneven
road surface. –
Suspension parts other than those
designated as Genuine NISSAN
parts are used. (If the vehicle height
or the vehicle body inclination is
changed, the system may not de-
tect an obstacle correctly.)
• Excessive noise (e.g., audio system
volume, an open vehicle window) 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, and the RAB sys-
tem warning light will illuminate in the ve-
hicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem 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.
SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:
• Always keep the parking sensors
O1
clean.
• If the parking sensors are dirty, wipe them off with a sof t cloth while being careful to
not damage them.

TURNING THE AEB SYSTEM
ON/OFF
Perform the following steps to turn the AEB
system on or off.
1. Press the
button until “Settings” dis-
plays in the vehicle information display
and then press the OK button. Use the
button to select “Driver Assistance.”
Then press the OK button.
2. Select “Emergency Brake” and press the OK button.
3. Select “Front” and press the OK button.
When the AEB system is turned off, the AEB
system warning light illuminates.
NOTE:
• The AEB system will be automatically turned on when the engine is re-
started.
• The I-FCW system is integrated into the AEB system. There is not a separate se-
lection in the vehicle information dis-
play for the I-FCW system. When the
AEB is turned off, the I–FCW system is
also turned off.
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
vehicle is driven at speeds over ap-
proximately 50 mph (80 km/h).
• The radar sensor may not detect a
vehicle 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.
• The system is designed to automati-
cally check the sensor’s functionality,
within certain limitations. The sys-
tem may not detect some forms of
obstructions 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.
5-92Starting and driving

•Tire type and condition may also af-
fect 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 ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer in-
formation” 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 dis-
tances.
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.
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 ve-
hicle 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 out- put 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 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
maintain control of the vehicle, but it can-
not prevent loss of vehicle control in all driv-
ing situations.
When the VDC system operates, the
indicator 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
andindicator lights come on in
the instrument panel. The VDC system au-
tomatically turns off when these indicator
lights are on.
The VDC OFF switch is used to turn off the
VDC system. The
indicator light and if
so equipped, the AEB system warning light
or the AEB with Pedestrian Detection sys-
tem warning light illuminates to indicate
the VDC, AEB, and AEB with Pedestrian De-
tection systems are off.

WARNING
• Never rely solely on the hill start as-
sist system to prevent the vehicle
from moving backward on a hill. Al-
ways drive carefully and attentively.
Depress the brake pedal when the
vehicle is stopped on a steep hill. Be
especially careful 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 possible
serious injury or death.
• The hill start assist system is not de-
signed to hold the vehicle at a stand-
still 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 may not prevent
the vehicle from rolling backwards
on a hill under all load or road condi-
tions. Always be prepared to depress
the brake pedal to prevent the ve-
hicle from rolling backwards. Failure
to do so may result in a collision or
serious personal injury. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied. This helps prevent the
vehicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator.
Hill start assist will operate automatically
under the following conditions:
• The shif t lever is moved to a forward or
reverse gear.
• The vehicle is stopped completely on a hill by applying the brake.
• The hill grade is above 10%.
The maximum holding time is two sec-
onds. Af ter two seconds the vehicle will be-
gin to roll back and hill start assist will stop
operating completely.
Hill start assist will not operate when the
shif t lever is moved to N (Neutral) or P (Park)
or on a flat and level road. 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.

so equipped)
5-134Starting and driving

WARNING
• The sonar (parking sensor) system is
a convenience but it is not a substi-
tute 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 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 af-
fect 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. •
The system is not designed to pre-
vent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect 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 sys-
tem volume or an open vehicle win-
dow) 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.

WARNING
• The use of tires other than those rec-
ommended or the mixed use of tires
of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the
ride, braking, handling, VDC system,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speedom-
eter calibration, headlight aim and
bumper height. Some of these ef-
fects may lead to accidents and
could result in serious personal
injury.
• For 2WD models, if your vehicle was
originally equipped with four tires
that were the same size and you are
only replacing two of the four tires,
install the new tires on the rear axle.
Placing new tires on the front axle
may cause loss of vehicle control in
some driving conditions and cause
an accident and personal injury. •
If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear, de-
grade vehicle handling characteris-
tics, affect the VDC system and/or in-
terference with the brake discs. Such
interference can lead to decreased
braking efficiency and/or early brake
pad wear. For additional information
on wheel off-set dimensions, refer to
“Wheels and tires” in the “Technical
and consumer information” section
of this manual.
• When replacing a wheel without the
TPMS, such as the spare tire, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on af ter 1 minute. Have
your tires replaced and/or TPMS sys-
tem reset as soon as possible. It is
recommended that you visit a
NISSAN dealer for this service.
• Replacing tires with those not origi-
nally specified by NISSAN could af-
fect the proper operation of the
TPMS. •
The TPMS sensor may be damaged if
it is not handled correctly. Be careful
when handling the TPMS sensor.
• When replacing the TPMS sensor, the
ID registration may be required. It is
recommended that you visit a
NISSAN dealer for ID registration.
• Do not use a valve stem cap that is
not specified by NISSAN. The valve
stem cap may become stuck.
• Be sure that the valve stem caps are
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of
pressure.
• Do not install a damaged or de-
formed wheel or tire even if it has
been repaired. Such wheels or tires
could have structural damage and
could fail without warning.
• The use of retread tires is not
recommended.
• For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety In-
formation” (Canada) in the Warranty
Information Booklet.
