2010 INFINITI FX warning

When driving on some roads, such as winding,
hilly, curved, narrow roads, or roads which are
under construction, the sensor may detect ve-
hicles in a different lane, or may temporarily not
detect a vehicle traveling ahead. This may
cause the system to work inappropriately.The detection of vehicles may also be affected
by vehicle operation (steering maneuver or trav-
eling position in the lane, etc.) or vehicle con-
dition.
If this occurs, the system may warn you
by blinking the system indicator and sounding
the chime unexpectedly. You will have to manu-
ally control the proper distance away from the
vehicle traveling ahead.

1. System set display with vehicle ahead
2. System set display without vehicle aheadSystem operation
WARNING
The Distance Control Assist system automati-
cally decelerates your vehicle to help assist the
driver to maintain a following distance from the
vehicle ahead. Manually brake when decelera-
tion is required to maintain a safe distance
upon sudden braking by the vehicle ahead or
when a vehicle suddenly appears in front of
you. Always stay alert when using the DCA
system.The Distance Control Assist (DCA) system helps
assist the driver to keep a following distance to
the vehicle ahead by braking and moving the
accelerator pedal upward in the normal driving
condition.
When a vehicle is detected ahead :
The vehicle ahead detection indicator comes
on.
When vehicle approaches a vehicle ahead :
●
If the driver’s foot is not on the accelerator
pedal, the system activates the brakes to
decelerate smoothly as necessary. If the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill within the limita-
tions of the system.
● If the driver’s foot is on the accelerator
pedal, the system moves the accelerator
pedal upward to assist the driver to release
the accelerator pedal.
When brake operation by driver is required :
The system alerts the driver by a warning chime
and blinking the vehicle ahead detection indi-
cator. If the driver’s foot is on the accelerator
pedal after the warning, the system moves the
accelerator pedal upward to assist the driver to
switch to the brake pedal.

The stoplights of the vehicle come on and the
brake pedal depresses when braking is per-
formed by the DCA system.
When the brake operates, a noise may be heard.
This is not a malfunction.
WARNING
●When the vehicle ahead detection indicator
light is not illuminated, system will not con-
trol or warn the driver.
● Never place your foot under the brake pedal.
Your foot may be caught when the system
controls the brake.
● Depending on the position of the accelerator
pedal, the system may not be able to assist
the driver to release the accelerator pedal
appropriately.
● If the vehicle ahead comes to a standstill,
the vehicle decelerates to a standstill within
the limitations of the system. The system
will release brake control with a warning
chime once it judges the vehicle is at a
standstill. To prevent the vehicle from mov-
ing, the driver must depress the brake pedal.
(The system will resume control automati-
cally once the system reaches 3 MPH
(5 km/h)). Overriding the system :
The following driver’s operation overrides the
system operation.
●
When the driver depresses the accelerator
pedal even further while the system is mov-
ing the accelerator pedal upward, the DCA
system control of the accelerator pedal is
canceled.
● When the driver’s foot is on the accelerator
pedal, the brake control by the system is not
operated.
● When the driver’s foot is on the brake pedal,
neither the brake control nor the alert by the
system operates.
● When the Intelligent Cruise Control system is
set, the DCA system will be cancelled.
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 system warns
the driver with the chime and DCA system
display. Decelerate by depressing the brake
pedal to maintain a safe vehicle 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 vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly.

NOTE:
The approach warning chime may sound and the
system display may blink when the sensor de-
tects some reflectors
Awhich are fitted on ve-
hicles in other lanes or on the side of the road.
This may cause the DCA system to operate inap-
propriately. The sensor may detect these reflec-
tors when the vehicle is driven on winding roads,
hilly roads or when entering or exiting a curve.
The sensor may also detect reflectors on narrow
roads or in road construction zones. In these
cases you will have to manually control the
proper distance ahead of your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
Condition A :
Under the following conditions, the Distance
Control Assist system is automatically can-
celed. The chime will sound and the Distance
Control Assist (DCA) system switch indicator
light will blink. The system will not be able to be
set.
●
When the VDC system is turned off
● When the VDC or ABS (including the traction
control system) operates
● When the SNOW mode switch is turned ON
● When driving into a strong light (i.e., sun-
light)

Action to take :
When the conditions listed above are no longer
present, turn the system off with the DCA
switch. Turn the DCA system back on to use the
system.Condition B :
When the sensor window is dirty, making it
impossible to detect a vehicle ahead, the DCA
system is automatically canceled.
The chime sounds and the system warning light
(orange) will come on and the “CLEAN SENSOR”
indicator will appear.
Action to take :
If the warning light comes on, park the vehicle
in a safe place, turn the engine off. Clean the
sensor window with a soft cloth and then
perform the settings again.Condition C :
When the DCA system is not operating properly,
the chime sounds and the system warning light
(“CRUISE” orange) will come on.
Action to take :
If the warning light comes on, park the vehicle
in a safe place. Turn the engine off, restart the
engine, and turn on the DCA system again.
If it is not possible to set the system or the
indicator stays on, it may indicate that the sys-
tem is malfunctioning. Although the vehicle is
still driveable under normal conditions, have the
vehicle checked at an INFINITI retailer.
