approximately 3 MPH (5 km/h).
If there is a potential risk of a forward
collision, the PFCW system will warn the
driver by blinking the vehicle ahead detection
indicator, and sounding an audible alert.

PFCW SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the PFCW system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The PFCW system cannot detect all
vehicles 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 PFCW 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 condi-
tions:
— Snow or heavy rain — Dirt, ice, snow or other material
covering the radar sensor
— Interference by other radar sources
— Snow or road spray from travel- ling vehicles.
— Driving in a tunnel
— Towing a trailer
. (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 ob-
structed.
. (Illustration D) When driving on a
steep 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, for example. 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.
SSD0253
When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a vehicle
traveling ahead. This may cause the PFCW
system to work inappropriately.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition.If this occurs, the system
may warn you by blinking the vehicle ahead
detection indicator and sounding the chime
unexpectedly. You will have to manually
control the proper distance away from the
vehicle traveling ahead.SYSTEM TEMPORARILY UNA-
VAILABLE
Condition A
When the radar sensor picks up interference
from another radar source, making it im-
possible to detect a vehicle ahead, the
PFCW system is automatically turned off.
The FEB system warning light (orange) will
illuminate.
Action to take:
When the above conditions no longer exist,
the PFCW system will resume automatically.

Condition B
Under the following conditions, making it
impossible to detect a vehicle ahead, the
PFCW system is automatically turned off.
The FEB system warning light (orange) will
illuminate and the “Forward Driving Aids
temporarily disabled Front Sensor blocked
See Owner’s Manual” warning message will
appear in the vehicle information display.
.When the sensor area of the front of the
vehicle is covered with dirt or is ob-
structed
Action to take:
If the warning light (orange) flashes, stop the
vehicle in a safe place, push the park button
to engage the P (Park) position and turn the
engine off. Clean the radar cover on the
front of the vehicle with a soft cloth, and
restart the engine. If the warning light
continues to illuminate, have the PFCW
system checked. It is recommended you visit
an INFINITI retailer for this service.
. When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next
to long walls)
Action to take:
When the above conditions no longer exist,
the PFCW system will resume automatically.
SYSTEM MALFUNCTION
If the PFCW system malfunctions, it will be
turned off automatically, a chime will sound,
the FEB system warning light (orange) will
illuminate and the "Malfunction" warning
message will appear in the vehicle informa-
tion display.
Action to take:
If the warning light (orange) illuminates, stop
the vehicle in a safe location. Turn the engine
off and restart the engine. If the warning
light continues to illuminate, have the PFCW
system checked. It is recommended you visit
an INFINITI retailer for this service.

SYSTEM MAINTENANCE
The radar sensoris located on the front of
the vehicle.
To keep the system operating properly, be
sure to observe the following:
. Always keep the sensor area on the front
of the vehicle clean.
. Do not strike or damage the areas around
the sensor.
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This

could cause failure or malfunction.
. Do not alter, remove or paint the front
bumper. It is recommended you contact
an INFINITI retailer before customizing
or restoring the front bumper.

WARNING
Failure to follow the warnings and
instructions for proper use of the DAA
system could result in serious injury or
death.
.The DAA 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 DAA system does not detect and
provide an alert of the driver’s lack of
attention or fatigue in every situa-
tion.
. It is the driver’s responsibility to:
— Stay alert.
— Drive safely.
— Keep the vehicle in the traveling lane.
— Be in control of the vehicle at all times.
— Avoid driving when tired.
— Avoid distractions (texting, etc).
The DAA system helps alert the driver if the
system detects a lack of attention or driving 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.
