∙ The following conditions may reduce the ability of the radar to detect other
vehicles:
– Severe weather
– Road spray
– Ice/frost/snow/dirt build-up on the vehicle
∙ Do not attach stickers (including transparent material), install accesso-
ries or apply additional paint near the
radar sensors. These conditions may
reduce the ability of the radar to de-
tect other vehicles. ∙ Excessive noise (e.g., audio system
volume, open vehicle window) will in-
terfere with the chime sound, and it
may not be heard.
NOTE:
In the case of several vehicles approach-
ing in a row (Illustration 1) or in the oppo-
site direction (Illustration 2), a chime may
not be sounded by the RCTA system af-
ter the first vehicle passes the sensors.

5-60Starting and driving

To reset at a slower cruising speed, use one
of the following three methods:1. Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the SET- switch and release it.
2. Push and hold the SET- switch. Release the switch when the vehicle slows
down to the desired speed.
3. Push, then quickly release the SET- switch. Each time you do this, the set
speed will decrease by about 1 mph
(1.6 km/h).
To resume the preset speed, push and re-
lease the RES+ switch. The vehicle will re-
sume the last set cruising speed when the
vehicle speed is over 25 mph (40 km/h).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 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 responsibility 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 system is not ef-
fective in all situations.
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
1
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, please refer to “Rear
Sonar System (RSS)” in this section.

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 environ-
ment, the weather, road surface
conditions, etc. Do not wait for the
system to operate. Operate the brake
pedal by yourself as soon as
necessary.
∙ If it is necessary to override RAB op- eration, strongly press the accelerator
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., at- tached 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.

SYSTEM MAINTENANCE
Observe the following items to ensure
proper operation of the system:∙ Always keep the parking sensors
1
clean.
∙ If the parking sensors are dirty, wipe them off with a sof t cloth while being
careful to not damage them. ∙ Do not subject the area around the
parking sensors
1to strong impact.
Also, do not remove or disassemble the
parking sensors. If the parking sensors
and peripheral areas are deformed in
an accident, etc., have the sensors
checked. It is recommended that you
visit a NISSAN dealer for this service.
∙ Do not install any stickers (including transparent stickers) or accessories on
the parking sensors
1and their sur-
rounding areas. This may cause a mal-
function or improper operation.
WARNING
Failure to follow the warnings and in-
structions for proper use of the AEB
system could result in serious injury or
death.
∙ The AEB system is a supplemental aid to the driver. It is not a replacement
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 system does not function in all driving, traffic, weather and road
conditions.
The AEB system can assist the driver when
there is a risk of a forward collision with the
vehicle ahead in the traveling lane.

AUTOMATIC EMERGENCY BRAKING
(AEB) (if so equipped)
5-130Starting and driving

Parking brake break-in
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
∙ The ABS is a sophisticated device, butit cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances 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 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 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) includes
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 for-
ward 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 malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS warning
light on the instrument panel. The brake sys-
tem then operates normally but without
anti-lock assistance.

WARNING
∙ The RSS is a convenience but it is not asubstitute 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 RSS as contained in this section.
The colors of the corner sonar indica-
tor and the distance guide lines in the
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 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. ∙ The system is not designed to prevent
contact 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.;
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 rear obstacles when the shif t
lever is in the R (Reverse) position.

The system is deactivated at speeds above
6 mph (10 km/h). It is reactivated at lower
speeds.
The intermittent tone will stop af ter 3 sec-
onds when an obstacle is detected by only
the corner sensor and the distance does
not change. The tone will stop when the
obstacle gets away from the vehicle.
Starting and driving5-177

∙ When replacing a wheel without theTPMS such as the spare tire, the TPMS
will not function and the low tire pres-
sure warning light will flash for ap-
proximately one 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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shif t lever to P
(Park). 4. Turn off the engine.
5. Raise the hood to warn other traffic
and to signal professional road assis-
tance personnel that you need assis-
tance.
6. Have all passengers get out of the ve- hicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
∙ Make sure the parking brake is se-curely applied and the Continuously
Variable Transmission (CVT) is shif ted
into P (Park).
∙ Never change tires when the vehicle is on a slope, ice or slippery areas. This is
hazardous.
∙ Never change tires if oncoming traffic is close to your vehicle. Wait for pro-
fessional road assistance.
A. Blocks
B. Flat tire
Blocking wheels
Place suitable blocks at both the front and
back of the wheel diagonally opposite the
flat tire to prevent the vehicle from moving
when it is jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
