2018 INFINITI Q50 HYBRID warning

5-102Starting and driving
SSD0253
When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the sensor
may detect vehicles in a different lane, or
may temporarily not detect a vehicle travel-
ing ahead. This may cause the 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 system
indicator and sounding the chime unexpect-
edly. You will have to manually control the
proper distance away from the vehicle
traveling ahead.

VAILABLE
Condition A
Under the following conditions, the DCA
system is automatically canceled. The chime
will sound and the “currently unavailable”
warning message will appear in the vehicle
information display. The system will not be
able to be set.
. When the VDC system is off (To use the
DCA system, turn on the VDC, then push
the dynamic driver assistance switch
.)

For details about the VDC system, see
“Vehicle Dynamic Control (VDC) system”
(P.5-130).

is turned to the SNOW mode (To use the
DCA system, turn the INFINITI Drive
Mode Selector to a mode other than the
SNOW mode, then turn on the dynamic
driver assistance switch

about the INFINITI Drive Mode Selector,
see “INFINITI Drive Mode Selector” (P.5-
21).
. When the radar signal is temporarily
interrupted
Action to take:
When the conditions listed above are no
longer present, turn the DCA system back on
to use the system.
Condition B
Under the following conditions, making it
impossible to detect a vehicle ahead, the
DCA system is automatically canceled.
The chime will sound, the driver assist
system forward indicator (orange) and the
“front radar obstruction” warning message
will appear in the vehicle information display.
. When the radar sensor area of the front bumper is covered with dirt or is ob-
structed
Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
stop the vehicle in a safe place, place the
shift lever in the P (Park) position and turn
the hybrid system off. When the radar signal
is temporarily interrupted, clean the sensor
area of the front bumper and restart the
hybrid system. If the warning message
continues to be displayed, have the DCA
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 DCA system will resume automatically.SYSTEM MALFUNCTION
When the DCA system is not operating
properly, the chime sounds, the driver assist
system forward indicator (orange) and the
system “malfunction” warning message will
appear in the vehicle information display. Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
stop the vehicle in a safe place and place the
shift lever in the P (Park) position. Turn the
hybrid system off, restart the hybrid system,
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
system is malfunctioning. Although the
vehicle is still driveable under normal con-
ditions, have the vehicle checked. It is
recommended you visit an INFINITI retailer
for this service.
SENSOR MAINTENANCE
The sensor for the DCA system is common
with the Intelligent Cruise Control (ICC)
system and is located behind the lower grille
of the front bumper.
For the sensor maintenance, see “Intelligent
Cruise Control (ICC)” (P.5-72).

WARNING
Failure to follow the warnings and
instructions for proper use of the FEB
system could result in serious personal
injury or death.
.The FEB system is a supplemental aid
to the driver. It is not a replacement
for the driver’s attention to traffic
conditions or responsibility to drive
safely. It cannot prevent accidents
due to carelessness or dangerous
driving techniques.
. The FEB system does not function in
all driving, traffic, weather and road
conditions.
The FEB system can assist the driver when
there is a risk of a forward collision with the
vehicle ahead in the traveling lane.
JVS1123X
The FEB system uses a radar sensorlocated behind the lower grille of the front
bumper to measure the distance to the
vehicle ahead in the same lane.

FEB SYSTEM OPERATION
The FEB system operates at speeds above
approximately 3 MPH (5 km/h).
If a risk of a forward collision is detected, the
FEB system will provide the first warning to
the driver by flashing the driver assist system
forward indicator (orange)
and the vehicle
ahead detection indicator (orange), and
providing an audible warning. In addition,
the FEB system pushes the accelerator
pedal up. If the driver releases the accel-
erator pedal, then the system applies partial
braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the FEB
system detects that there is still the possi-
bility of a forward collision, the system will
automatically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the FEB system
issues the second visual (red) and audible
warning and automatically applies harder
braking.
NOTE:
The vehicle’s stop lights come on when
braking is performed by the FEB system.
Depending on vehicle speed and distance to
the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may

Perform the following steps to turn the FEB
system on or off.
1. Push the MENU button
and touch
[Driver Assistance] on the lower display

2. Touch [Emergency Assist].
3. Touch [Forward emergency braking] to turn the system ON/OFF.
When the FEB system is turned off, the FEB
system warning light (orange)
illuminates.
The FEB system will be automatically turned
ON when the hybrid system is restarted.
NOTE:
The Predictive Forward Collision Warning
(PFCW) system is integrated into the FEB
system. There is not a separate selection in
the display for the PFCW system. When the
FEB is turned off, the PFCW system is also
turned off.

FEB SYSTEM LIMITATIONS
WARNING
Listed below are the system limitations
for the FEB system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.
.The FEB 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
. The radar sensor has some perfor-
mance limitations. If a stationary
vehicle is in the vehicle’s path, the
FEB system will not function when
the vehicle is driven at speeds over
approximately 45 MPH (70 km/h).
. The radar sensor may not detect a
vehicle ahead in the following condi-
tions:
— Dirt, ice, snow or other material covering the radar sensor. — Interference by other radar
sources.
— Snow or road spray from travel- ing vehicles.
— If the vehicle ahead is narrow (e.g. motorcycle)
— When driving on a steep downhill slope or roads with sharp curves.
. In some road or traffic conditions, the
FEB system may unexpectedly push
the accelerator pedal up or apply
partial braking. When acceleration is
necessary, continue to depress the
accelerator pedal to override the
system.
. Braking distances increase on slip-
pery surfaces.
. 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.

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 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
