WARNING
Failure to follow the warnings and
instructions for proper use of the
AEB with pedestrian detection sys-
tem could result in serious injury or
death.
.
The AEB with pedestrian detec-
tion system is a supplemental aid
to the driver. It is not a replace-
ment for the driver’s attention to
traffic conditions or responsibility
to drive safely. It cannot prevent
accidents due to carelessness or
dangerous driving techniques.
. The AEB with pedestrian detec-
tion system does not function in
all driving, traffic, weather and
road conditions.
The AEB with pedestrian detection sys-
tem can assist the driver when there is a
risk of a forward collision with
. a vehicle ahead in the travelling lane
. a pedestrian ahead in the travelling
lane
AUTOMATIC EMERGENCY BRAKING (AEB)
WITH PEDESTRIAN DETECTION SYSTEM

— When your vehicle or the ve-hicle or pedestrian ahead
moves quickly or significantly
such that the system cannot
detect and react in time (for
example, pedestrian moving
quickly toward the vehicle at
close range, vehicle cutting in,
changing lanes, making a
turn, steering abruptly, sud-
den acceleration or decelera-
tion).
— When the vehicle or pedes- trian is offset from the vehi-
cle’s forward path.
— If the speed difference be- tween the two vehicles is
small.
— The pedestrian’s profile is par- tially obscured or unidentifi-
able; for example, due to
transporting luggage, push-
ing a stroller, wearing bulky
or very loose-fitting clothing
or accessories, or being in a
unique posture (such as rais-
ing hands).
— There is poor contrast of a person to the background,
such as having clothing color
or pattern which is similar to the background.
— For approximately 15 seconds after starting the engine
— If the vehicle ahead has a unique or unusual shape, ex-
tremely low or high clearance
heights, or unusual cargo
loading or is narrow (for ex-
ample, a motorcycle).
— When the vehicle or pedes- trian is located near a traffic
sign, a reflective area (for ex-
ample, water on road), or is in
a shadow.
— When multiple pedestrians are grouped together.
— When the view of the pedes- trian is obscured by a vehicle
or other object.
— While towing a trailer or other vehicle.
. The system performance may be
degraded in the following condi-
tions:
— The vehicle is driven on a
slippery road.
— The vehicle is driven on a slope. — Excessively heavy baggage is
loaded in the rear seat or the
cargo area of your vehicle.
. The system is designed to auto-
matically check the sensor (radar
and camera)’s functionality, with-
in certain limitations. The system
may not detect some forms of
obstruction of the sensor area
such as ice, snow or stickers, for
example. In these cases, the sys-
tem may not be able to warn the
driver properly. Be sure that you
check, clean and clear sensor
areas regularly.
. In some road and traffic condi-
tions, the AEB with pedestrian
detection system may unexpect-
edly apply partial braking. When
acceleration is necessary, de-
press the accelerator pedal to
override the system.
. The AEB with pedestrian detec-
tion system may operate when a
pattern, object, shadow or lights
are detected that are similar to
the outline of vehicles or pedes-
trians, or if they are the same size
and position as a vehicle or mo-
torcycle’s tail lights.

WARNING
Failure to follow the warnings and
instructions for proper use of the
RAB system could result in serious
injury or death.
. The RAB system is a supplemen-
tal aid to the driver. It is not a
replacement 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
system. It is the driver’s respon-
sibility to stay alert, drive safely,
and be in control of the vehicle at
all times.
. There is a limitation to the RAB
system capability. The RAB sys-
tem is not effective in all situa-
tions.
The RAB system can assist the driver
when the vehicle is backing up and
approaching objects directly behind the
vehicle.
REAR AUTOMATIC BRAKING (RAB)

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.).
— 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.)
. When towing a trailer or other
vehicle, turn the RAB system off
to prevent the occurrence of an
unexpected accident resulting
from sudden system operation.
(See “RAB system operation” (P.5-
118).) .
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
“System fault See Owner’s Manual” warn-
ing message will appear in the vehicle
information display.

SYSTEM MAINTENANCE
The sonar sensorsare located on the
rear bumper. Observe the following items
to ensure proper operation of the system:
. Always keep the sonar sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such
as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors. .
Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked. It is recommended
that you visit a NISSAN dealer for this
service.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.
CAUTION
During the first 1,200 miles (2,000
km), follow these recommendations
to obtain maximum engine perfor-
mance and ensure the future relia-
bility and economy of your new
vehicle.
Failure to follow these recommenda-
tions may result in shortened engine
life and reduced engine perfor-
mance.
. Avoid driving for long periods at con-
stant speed, either fast or slow. Do not
run the engine over 4,000 rpm.
. Do not accelerate at full throttle in any
gear.
. Avoid quick starts.
. Avoid hard braking as much as possi-
ble.
. Do not tow a trailer for the first 500
miles (805 km).
BREAK-IN SCHEDULE

5-124Starting and driving
.Keep your engine tuned up.
. Follow the recommended scheduled
maintenance.
. Keep the tires inflated to the correct
pressure. Low tire pressure increases
tire wear and lowers fuel economy.
. Keep the wheels in correct alignment.
Improper alignment increases tire
wear and lowers fuel economy.
. Use the recommended viscosity en-
gine oil. (See “Engine oil and oil filter
recommendation” (P.10-6).)
WARNING
.Do not attempt to raise two
wheels off the ground and shift
the transmission to any drive or
reverse position with the engine
running. Doing so may result in
drivetrain damage or unexpected
vehicle movement which could
result in serious vehicle damage
or personal injury.
. Do not attempt to test a 4WD
equipped vehicle on a 2-wheel
dynamometer or similar equip-
ment even if the other two
wheels are raised off the ground.
Make sure you inform test facility
personnel that your vehicle is
equipped with 4WD before it is
placed on a dynamometer. Using
the wrong test equipment may
result in drivetrain damage or
unexpected vehicle movement
which could result in serious ve-
hicle damage or personal injury.
CAUTION
.Do not drive the vehicle in the 4HI
or 4LO position on dry hard sur-
face roads. Driving on dry, hard
surfaces in 4HI or 4LO may cause
unnecessary noise, tire wear and
increased fuel consumption.
If the Four-Wheel Drive (4WD)
warning light turns on when driv-
ing on dry hard surface roads:
— in the 4HI position, shift the
4WD shift switch to AUTO.
— in the 4LO position, stop the vehicle and shift the transmis-
sion lever to the N (Neutral)
position with the brake pedal
depressed and shift the 4WD
shift switch to AUTO.
If the 4WD warning light is still
on after the above operation,
have your vehicle checked as
soon as possible. It is recom-
mended you visit a NISSAN
dealer for this service.
. The transfer case may be da-
maged if you continue driving
with the 4WD warning light blink-
ing.

sensors. This may cause a malfunction
of the sonar sensors.
WARNING
If the engine is not running or is
turned off while driving, the power
assist for the steering will not work.
Steering will be harder to operate.
The power assisted steering uses a hy-
draulic pump, driven by the engine, to
assist steering.
If the engine stops or the drive belt
breaks, you will still have control of the
vehicle. However, much greater steering
effort is needed, especially in sharp turns
and at low speeds.
