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:
– IllustrationA: 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
“Unavailable: Side Radar Obstruction”
warning message will appear in the vehicle
information 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
indicator (orange) will appear in the vehicle
information display.
NOTE:
If the BSW system stops working, the
RCTA system will also stop working.
Action to take
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the mes-
sage 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.

If the radar sensor1detects a slower
moving vehicle ahead, the system will re-
duce the vehicle speed so that your vehicle
follows the vehicle in front at the selected
distance.
The system automatically controls the
throttle and applies the brakes (up to ap-
proximately 40% of vehicle braking power)
if necessary.
The detection range of the sensor is ap-
proximately 650 f t (200 m) ahead.

Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that
vehicle 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 affected
by vehicle operation (steering maneuver or
driving position in the lane) or traffic or ve-
hicle condition (for example, if a vehicle is
being driven with some damage).
Automatic cancellation
A chime sounds under the following condi-
tions and the control is automatically can-
celed: ∙ When the vehicle ahead is not detected and your vehicle is traveling below the
speed of 15 mph (24 km/h)
∙ When the system judges the vehicle is at a standstill
∙ When the shif t lever is not in the D (Drive) position, Manual mode or L (Low) range.
∙ When the parking brake system is ap- plied
∙ When the VDC system is turned off
∙ When VDC operates
∙
When distance measurement becomes
impaired due to adhesion of dirt or ob-
struction to the sensor
∙ When a wheel slips
∙ When the radar signal is temporarily in- terrupted

VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE LIMITATIONS
WARNING
Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The ICC system is primarily intendedfor use on straight, dry, open roads
with light traffic. It is not advisable to
use the ICC system in city traffic or
congested areas.
∙ The ICC system will not adapt auto- matically to road conditions. This sys-
tem should be used in evenly flowing
traffic. Do not use the system on roads
with sharp curves, or on icy roads, in
heavy rain or in fog. ∙ As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absentminded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the ve-
hicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.
∙ If the vehicle ahead comes to a stop, the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel once it judges
that the vehicle has come to a stand-
still and sound a warning chime. To
prevent the vehicle from moving, the
driver must depress the brake pedal.
∙ Always pay attention to the operation of the vehicle and be ready to manu-
ally control the proper following dis-
tance. The ICC system may not be able
to maintain the selected distance be-
tween vehicles (following distance) or
selected vehicle speed under some
circumstances. ∙ 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 vehicle
may go beyond the set vehicle
speed and frequent braking may re-
sult 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
