WARNING
Listed below are the system limitations
for the I-FCW system. Failure to operate
the vehicle in accordance with these
system limitations could result in seri-
ous injury or death.
∙ The I-FCW system cannot detect allvehicles under all conditions.
∙ The radar sensor does not detect the following objects:
– Pedestrians, animals or obstacles in the roadway – Oncoming vehicles
– Crossing vehicles
∙ (Illustration A) The I-FCW system does not function when a vehicle ahead is a
narrow vehicle, such as a motorcycle.
∙ The radar sensor may not detect a vehicle ahead in the following
conditions:
– Snow or heavy rain
– Dirt, ice, snow or other material covering the radar sensor. – Interference by other radar
sources.
– Snow or road spray from traveling vehicles.
– Driving in a tunnel
– (Illustration B) When the vehicle ahead is being towed.
– (Illustration C) When the distance to the vehicle ahead is too close,
the beam of the radar sensor is
obstructed.

– (Illustration D) When driving on asteep downhill slope or roads with
sharp curves.
∙ The system is designed to automati- cally check the sensor’s functionality,
within certain limitations. The system
may not detect some forms of ob-
struction of the sensor area such as
ice, snow, stickers, etc. In these cases,
the system may not be able to warn
the driver properly. Be sure that you
check, clean and clear the sensor area
regularly.
∙ Excessive noise will interfere with the warning chime sound, and the chime
may not be heard.

SYSTEM TEMPORARILY
UNAVAILABLE
Condition A
When the radar sensor picks up interfer-
ence from another radar source, making it
impossible to detect a vehicle ahead, the
I-FCW system is automatically turned off.
The AEB system warning light (orange) will
illuminate.
Action to take
When the above conditions no longer exist,
the I-FCW system will resume automati-
cally.
Condition B
When the radar sensor of the front bumper
is covered with dirt or is obstructed, the
I-FCW system will automatically be can-
celed. The chime will sound and the “Not
Available: Front Radar Blocked” warning
message will appear in the vehicle infor-
mation display.

Page 417 of 592
Action to take:
If the warning message appears, stop the
vehicle in a safe place, place the shif t lever
in the P (Park) position, and turn the engine
off. When the radar signal is temporarily
interrupted, clean the sensor area of the
front bumper and restart the engine. If the
“Not Available: Front Radar Blocked” warn-
ing message continues to be displayed,
have the system checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
Condition C
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snowfields, driving next to
long walls), the system may illuminate the
system warning light and display the “Not
Available: Front Radar Blocked” message.
Action to take:
When the above driving conditions no lon-
ger exist, turn the system back on.
NOTE:
If the AEB system stops working, the
I-FCW system will also stop working.SYSTEM MALFUNCTION
If the I-FCW system malfunctions, it will be
turned off automatically, a chime will
sound, the AEB system warning light
(orange) will illuminate and the warning
message [Malfunction] will appear in the
vehicle information display.
Action to take
If the warning light (orange) comes on, stop
the vehicle in a safe location, turn the en-
gine off and restart the engine. If the warn-
ing light continues to illuminate, have the
I-FCW system checked. It is recommended
that you visit a NISSAN dealer for this ser-
vice.
SYSTEM MAINTENANCE
The sensor1is located on the front of the
vehicle.
To keep the system operating properly, be
sure to observe the following:
∙ Always keep the sensor area of the front bumper clean.
∙ Do not strike or damage the areas around the sensor.
∙ Do not cover or attach stickers or simi- lar objects on the front bumper near
the sensor area. This could cause failure
or malfunction.

∙ Do not attach metallic objects near thesensor area (brush guard, etc.). This
could cause failure or malfunction.
∙ Do not alter, remove or paint the front bumper. Before customizing or restor-
ing the front bumper, it is recom-
mended that you visit a NISSAN dealer.

system could result in serious injury or
death.
∙ The I–DA system is only a warning to inform the driver of a potential lack of
driver attention or drowsiness. It will
not steer the vehicle or prevent loss of
control.
∙ The I–DA system does not detect and provide an alert of the driver’s lack of
attention or fatigue in every situation.

∙ avoid distractions (texting, etc).
INTELLIGENT DRIVER ALERTNESS
(I-DA)
5-160Starting and driving
Page 419 of 592
The I–DA system helps alert the driver if the
system detects a lack of attention or driv-
ing fatigue.
The system monitors driving style and
steering behavior over a period of time,
and it detects changes from the normal
pattern. If the system detects that driver
attention is decreasing over a period of
time, the system uses audible and visual
warnings to suggest that the driver take a
break.
INTELLIGENT DRIVER ALERTNESS
SYSTEM OPERATION
If the system detects driver fatigue or that
driver attention is decreasing, the mes-
sage “Take a break?” appears in the vehicle
information display and a chime sounds
when the vehicle is driven at speeds above
37 mph (60 km/h).
The system continuously monitors driver
attention and can provide multiple warn-
ings per trip.The system resets and starts reassessing
driving style and steering behavior when
the ignition switch is cycled from the ON to
the OFF position and back to the ON posi-
tion.
