WARNING
Failure to follow the warnings and in-
structions for proper use of the RAB
system could result in serious injury or
death.
• The RAB system is a supplemental
aid to the driver. It is not a replace-
ment for proper driving procedures.
Always use the side and rear mirrors
and turn and look in the direction you
will move before and while backing
up. Never rely solely on the RAB sys-
tem. It is the driver’s responsibility to
stay alert, drive safely, and be in con-
trol of the vehicle at all times.
• There is a limitation to the RAB sys-
tem capability. The RAB system is not
effective in all situations.
• 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. The RAB system can assist the driver when
the vehicle is backing up and approaching
objects directly behind the vehicle.
The RAB system detects obstacles behind
the vehicle using the parking sensors
O1
located on the rear bumper.
NOTE:
You can temporarily cancel the sonar
function in the vehicle, but the RAB sys-
tem will continue to operate. For addi-
tional information, see “Front and Rear
Sonar System” (P. 5-116).

RAB SYSTEM OPERATION
1RAB system warning light and RAB sys-
tem warning indicator
2Steering-wheel-mounted controls (lef t
side)
3Center display (if so equipped) When the shif t 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 (for
vehicles with the Intelligent Around View
Monitor system), and the system will chime
three times. The system will then auto-
matically apply the brakes. Af ter the auto-
matic brake application, the driver must
depress the brake pedal to maintain brake
pressure.
NOTE:
• The brake 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 malfunction.
LSD3381
Starting and driving5-81

–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 follow-
ing conditions to prevent the occur-
rence of an unexpected accident re-
sulting 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.
– The vehicle is towing an object (if
so equipped). –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.

AEB WITH PEDESTRIAN
DETECTION SYSTEM OPERATION1. Vehicle ahead detection indicator
2. AEB with Pedestrian Detection emer-gency warning indicator 3. AEB with Pedestrian Detection system
warning light
The AEB system operates at speeds above
approximately 3 mph (5 km/h). For the pe-
destrian detection function, the system
operates at speeds between6–37mph(10
– 60 km/h).
If a risk of a forward collision is detected,
the AEB with Pedestrian Detection system
will firstly provide the warning to the driver
by flashing the vehicle ahead detection in-
dicator (yellow) in the vehicle information
display and providing an audible alert. If the
driver applies the brakes quickly and force-
fully af ter the warning, and the AEB with
Pedestrian Detection system detects that
there is still the possibility of a forward col-
lision, the system will automatically in-
crease the braking force.
If the driver does not take action, the AEB
with Pedestrian Detection system issues
the second visual (flashing) (red and white)
and audible warning. If the driver releases
the accelerator pedal, then the system ap-
plies partial braking. If the risk of a collision
becomes imminent, the AEB with Pedes-
trian Detection system applies harder
braking automatically.
LSD2773
5-86Starting and driving

While the AEB with Pedestrian Detection
system is operating, you may hear the
sound of brake operation. This is normal
and indicates that the AEB with Pedestrian
Detection system is operating properly.
NOTE:
The vehicle’s brake lights come on when
any braking is performed by the AEB
with Pedestrian Detection system.
Depending on vehicle speed and distance
to the vehicle or pedestrian ahead, as well
as driving and roadway conditions, the sys-
tem may help the driver avoid a forward
collision or may help mitigate the conse-
quences if a collision should be unavoid-
able. If the driver is handling the steering
wheel, accelerating or braking, the AEB with
Pedestrian Detection system will function
later or will not function.The automatic braking will cease under the
following conditions:
• When the steering wheel is turned to
avoid a collision.
• When the accelerator pedal is depressed.
• When there is no longer a vehicle or a pedestrian detected ahead.
If the AEB with Pedestrian Detection sys-
tem has stopped the vehicle, the vehicle
will remain at a standstill for approximately
2 seconds before the brakes are released.

•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 follow-
ing 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.
• The sonar sensors may cause mal-
function when a horn, etc. sounds or
there is an ultrasonic source (such as
parking sensors of other vehicles)
around the vehicle because the so-
nar sensors detect the distance be-
tween the vehicle and the obstacle
by detecting the sound wave re-
flected from the surface of an
obstacle.
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.
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.

CAUTION
• Af ter wiper blade replacement, re-
turn the wiper arm to its original po-
sition; otherwise it may be damaged
when the hood is opened.
• Make sure the wiper blades contact
the glass; otherwise the arms may be
damaged from wind pressure.
If you wax the surface of the hood, be care-
ful not to let wax get into the washer nozzle
OD. This may cause clogging or improper
windshield-washer operation. If wax gets
into the nozzle, remove it with a needle or
small pin
OC. If the brakes do not operate properly, have
the brakes checked. It is recommended
that you visit a NISSAN dealer for this
service.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-
adjust every time the brake pedal is
applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to
normal. It is recommended that you
visit a NISSAN dealer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched
scraping or screeching sound will be heard
when the vehicle is in motion. The noise will
be heard whether or not the brake pedal is
depressed. Have the brakes checked as
soon as possible if the wear indicator
sound is heard.LDI2731
BRAKES
8-18Do-it-yourself

Brakes:Check that the brakes do not pull
the vehicle to one side when applied.
Continuously Variable Transmission
(CVT) P (Park) position mechanism: On a
fairly steep hill check that the vehicle is held
securely with the shif t lever in the P (Park)
position without applying any brakes.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjustment, it is recom-
mended that you visit a NISSAN dealer for
this service.
Seats: Check seat position controls such
as seat adjusters, seatback recliner, etc., to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints/headrests
move up and down smoothly and the locks
(if so equipped) hold securely in all latched
positions.
Seat belts: Check that all parts of the seat
belt system (for example, buckles, anchors,
adjusters and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage. Steering wheel:
Check for changes in the
steering system, such as excessive free
play, hard steering or strange noises.
Warning lights and chimes: Make sure all
warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*: Check
that the wipers and washer operate prop-
erly and that the wipers do not streak.
Under the hood and vehicle
The maintenance items listed here should
be checked periodically (for example, each
time you check the engine oil or refuel).
Battery* (for maintenance free batter-
ies): This vehicle is equipped with a sealed
maintenance free battery. It is recom-
mended that you visit a NISSAN dealer for
service.
NOTE:
Care should be taken to avoid situations
that can lead to potential battery dis-
charge and potential no-start conditions
such as:
1. Installation or extended use of elec-
tronic accessories that consume bat-
tery power when the engine is not run-
ning (Phone chargers, GPS, DVD
players, etc.).
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the battery may need to
be charged to maintain battery health.
Brake fluid level*: Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*: Check the coolant
level when the engine is cold.
Engine drive belts*: Make sure the drive
belts are not frayed, worn, cracked or oily.
