RCTA SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the RCTA system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ Always check surroundings and turnto check what is behind you before
backing up. The radar sensors detect
approaching (moving) vehicles. The
radar sensors cannot detect every
object such as:
– Pedestrians, bicycles, motorcycles, animals or child-operated toy
vehicles
– A vehicle that is passing at speeds greater than approximately
19 mph (30 km/h)
– A vehicle that is passing at speeds lower than approximately 5 mph
(8 km/h)
∙ The radar sensors may not detect ap- proaching vehicles in certain
situations:
– Illustration
A: When a vehicle
parked next to you obstructs the
beam of the radar sensor.

– IllustrationB: When the vehicle is
parked in an angled parking space.
– Illustration
C: When the vehicle is
parked on inclined ground.
– Illustration
D: When an approach-
ing vehicle turns into your vehicle’s
parking lot aisle.
– Illustration
E: When the angle
formed by your vehicle and ap-
proaching vehicle is small.
∙ 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.

SYSTEM TEMPORARILY
UNAVAILABLE
When radar blockage is detected, the sys-
tem will be deactivated automatically. The
“Side Radar Obstruction” warning message
will appear and the BSW/RCTA indicator
(white) will blink
Ain the vehicle informa-
tion display.
The systems are not available until the
conditions no longer exist.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take
When the above conditions no longer exist,
the system will resume automatically.

Malfunction
When the RCTA system malfunctions, it will
turn off automatically. The system mal-
function warning message with the
BSW/RCTA indicator (orange) will appear in
the vehicle information display.
NOTE:
If the BSW system stops working, the
RCTA system (if so equipped) will also
stop working.
Action to take
Stop the vehicle in a safe location, turn the
engine off and restart the engine. If the
message continues to appear, have the
system checked. It is recommended that
you visit a NISSAN dealer for this service.
SYSTEM MAINTENANCE
The two radar sensors1for the BSW and
RCTA systems are located near the rear
bumper. Always keep the area near the ra-
dar sensors clean.
The radar sensors may be blocked by tem-
porary ambient conditions such as splash-
ing water, mist or fog.
The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the radar sensors.
Check for and remove objects obstructing
the area around the radar sensors. Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the radar sensors.
Do not strike or damage the area around
the radar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the radar sensors is damaged due to a
collision.

5-44Starting and driving

∙ Push and release the ACCEL/RESswitch. Each time you do this, the set
speed increases by about 1 mph
(1.6 km/h).
To reset at a slower cruising speed, use
one of the following three methods:
∙ Lightly tap the brake pedal. When the vehicle attains the desired speed, push
the COAST/SET switch and release it.
∙ Push and hold the COAST/SET switch. Release the switch when the vehicle
slows to the desired speed.
∙ Push and release the COAST/SET switch. Each time you do this, the set
speed decreases by about 1 mph
(1.6 km/h).
To resume the preset speed, push and
release the ACCEL/RES switch. The vehicle
returns to 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 ICC sys-
tem could result in serious injury or
death.
∙ The ICC system is only an aid to assist the driver and is not a collision warn-
ing or avoidance device. It is the driv-
er’s responsibility to stay alert, drive
safely and be in control of the vehicle
at all times.
∙ Always observe posted speed limits and do not set the speed over them.
∙ Always drive carefully and attentively when using the ICC system. Read and
understand the Owner’s Manual thor-
oughly before using the ICC system.
To avoid serious injury or death, do
not rely on the system to prevent ac-
cidents or to control the vehicle’s
speed in emergency situations. Do
not use the ICC system except in ap-
propriate road and traffic conditions. The ICC system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and di-
rection.
The ICC system uses a radar sensor
A
located on the front of the vehicle to detect
vehicles traveling ahead.
If the radar sensor detects a slower moving
vehicle ahead, the system will reduce the
vehicle speed so that your vehicle follows
the vehicle in front at the selected distance.
The detection range of the sensor is ap-
proximately 390 f t (120 m) ahead.

1. Long 200 (60)
2. Middle 150 (45)
3. Short 90 (30)
∙ The distance to the vehicle ahead will change according to the vehicle speed.
The higher the vehicle speed, the longer
the distance.
∙ If the engine is stopped, the set distance becomes “long.” (Each time the engine
is started, the initial setting becomes
“long.”)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that ve-
hicle or if another vehicle cuts in, the sys-
tem warns the driver with the chime and
ICC system display. Decelerate by depress-
ing the brake pedal to maintain a safe ve-
hicle distance if:
∙ The chime sounds.
∙ The vehicle ahead detection indicator blinks.
The warning chime may not sound in
some cases when there is a short distance
between vehicles. Some examples are: ∙ When the vehicles are traveling at the same speed and the distance between
vehicles is not changing.
∙ When the vehicle ahead is traveling faster and the distance between ve-
hicles is increasing.
∙ When a vehicle cuts in near your vehicle.
The warning chime will not sound when: ∙ The vehicle approaches other vehicles that are parked or moving slowly.
∙ The accelerator pedal is depressed, overriding the system. NOTE:
The approach warning chime may sound
and the system display may blink when
the ICC sensor detects objects on the
side of the vehicle or on the side of the
road. This may cause the ICC system to
decelerate or accelerate the vehicle. The
ICC sensor may detect these objects
when the vehicle is driven on winding
roads, narrow roads, hilly roads, or when
entering or exiting a curve. In these
cases you will have to manually control
the proper distance ahead of your ve-
hicle.
Also, the sensor sensitivity can be af-
fected by vehicle operation (steering
maneuver or driving position in the lane)
or traffic or vehicle condition (for ex-
ample, if a vehicle is being driven with
some damage).

∙ The system may not detect the ve-hicle in front of you in certain road or
weather conditions. To avoid acci-
dents, never use the ICC system under
the following conditions:
– On roads where the traffic is heavy or there are sharp curves
– On slippery road surfaces such as on ice or snow, etc.
– During bad weather (rain, fog, snow, etc.)
– When rain, snow or dirt adhere to the bumper around the distance
sensor
– On steep downhill roads (the ve- hicle may go beyond the set ve-
hicle speed and frequent braking
may result in overheating the
brakes)
– On repeated uphill and downhill roads
– When traffic conditions make it dif- ficult to keep a proper distance be-
tween vehicles because of fre-
quent acceleration or deceleration – Interference by other radar
sources
∙ Do not use the ICC system if you are towing a trailer. The system may not
detect a vehicle ahead.
∙ In some road or traffic conditions, a vehicle or object can unexpectedly
come into the sensor detection zone
and cause automatic braking. Always
stay alert and avoid using the ICC sys-
tem where not recommended in this
warning section.
The radar sensor will not detect the follow-
ing objects: ∙ Stationary and slow moving vehicles
∙ Pedestrians or objects in the roadway
∙ Oncoming vehicles in the same lane
∙ Motorcycles traveling offset in the travel lane
The following are some conditions in which
the sensor cannot properly detect a ve-
hicle ahead and the system may not oper-
ate properly: ∙ When snow or road spray from traveling vehicles reduces the sensor’s detection. ∙ When excessively heavy baggage is
loaded in the rear seat or the trunk of
your vehicle.
The ICC system is designed to automati-
cally check the sensor’s operation within
the limitations of the system.
The detection zone of the ICC sensor is
limited. A vehicle ahead must be in the de-
tection zone for the vehicle-to-vehicle dis-
tance detection mode to maintain the se-
lected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within
the same lane of travel. Motorcycles may
not be detected in the same lane ahead if
they are traveling offset from the centerline
of the lane. A vehicle that is entering the
lane ahead may not be detected until the
vehicle has completely moved into the
lane.
If this occurs, the ICC system may warn
you by blinking the system indicator and
sounding the chime. The driver may
have to manually control the proper dis-
tance away from the vehicle traveling
ahead.
