Infiniti FX35, FX50 (S51). Manual - part 389
CCS-376
< SYMPTOM DIAGNOSIS >
[DCA]
NORMAL OPERATING CONDITION
• The detection zone of the sensor is limited. A vehicle ahead
must be in the detection zone for the system to operate.
- 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 center line of the lane. A vehicle that is enter-
ing the lane ahead may not be detected until the vehicle has
completely moved into the lane. If this occurs, the system
may warn driver by blinking the system indicator and sound-
ing the chime. The driver may have to manually control the
proper distance away from vehicle traveling ahead.
- When driving on some roads, such as winding, hilly, curved,
narrow roads, or roads which are under construction, the sen-
sor may detect vehicles in a different lane, or may temporarily
not detect a vehicle traveling ahead. This may cause the sys-
tem to work inappropriately. The detection of vehicles may
also be affected by vehicle operation (steering maneuver or
traveling position in the lane, etc.) or vehicle condition. If this
occurs, the system may warn driver by blinking the system
indicator and sounding the chime unexpectedly. The driver
will have to manually control the proper distance away from
the vehicle traveling ahead.
• The approach warning chime may sound and the system dis-
play may blink when the sensor detects some reflectors
which are fitted on vehicles in other lanes or on the side of the
road. This may cause the DCA system to operate inappropri-
ately. The sensor may detect these reflectors when the vehicle
is driven on winding roads, hilly roads or when entering or
exiting a curve. The sensor may also detect reflectors on nar-
row roads or in road construction zones. In these cases driver
will have to manually control the proper distance ahead of
own vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving position in
the lane) or traffic or vehicle condition (for example, if a vehi-
cle is being driven with some damage).
• The DCA system automatically decelerates own vehicle to help assist the driver to maintain a follow-
ing distance from the vehicle ahead. Manually brake when deceleration is required to maintain a safe
distance upon sudden braking by the vehicle ahead or when a vehicle suddenly appears in front of
own vehicle. Always stay alert when using the DCA system.
• When the vehicle ahead detection indicator lamp is not illuminated, system will not control or warn
the driver.
• Never place a foot under the brake pedal. A 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
