2014 INFINITI Q50 HYBRID light

The LDW and LDP systems monitor the lane
markers on the traveling lane using the
camera unit
*1located above the inside
mirror. When the camera unit detects that
the vehicle is traveling close to either the
left or the right of the traveling lane, the
driver assist system lane indicator (orange)
in the vehicle information display blinks
and a warning chime sounds. When the
LDP system is on, it will automatically
apply a steering operation for a short
period of time.
LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
. This system is only a warning device to
inform the driver of a potential unin-
tended lane departure. It will not steer
the vehicle or prevent loss of control. It
is the driver’ s responsibility to stay
alert, drive safely, keep the vehicle in
the traveling lane, and be in control of
the vehicle at all times.
. The system will not operate at speeds below approximately 45 MPH (70 km/h)
or if it cannot detect lane markers.
. If the LDW system malfunctions, it will
cancel automatically, and the LDW mal-
function message will appear in the
vehicle information display.
. If the LDW malfunction message ap-
pears, pull off the road to a safe location
and stop the vehicle. Turn the INFINITI
Direct Response Hybrid
®System off and
restart the hybrid system. If the LDW
malfunction message continues to ap-
pear, have the system checked by an
INFINITI retailer.
. Excessive noise will interfere with the
warning chime sound, and the chime
may not be heard.
The system may not function properly
under the following conditions:
.On roads where there are multiple
parallel lane markers; lane markers
that are faded or not painted clearly;
yellow painted lane markers; non-stan-
dard lane markers; or lane markers
covered with water, dirt, snow, etc.
. On roads where the discontinued lane
markers are still detectable. .
On roads where there are sharp curves.
. On roads where there are sharply
contrasting objects, such as shadows,
snow, water, wheel ruts, seams or lines
remaining after road repairs. (The Lane
Departure Warning (LDW) system could
detect these items as lane markers.)
. On roads where the traveling lane
merges or separates.
. When the vehicle’s traveling direction
does not align with the lane marker.
. When traveling close to the vehicle in
front of you, which obstructs the lane
camera unit detection range.
. When rain, snow or dirt adheres to the
windshield in front of the lane camera
unit.
. When the headlights are not bright due
to dirt on the lens or if the aiming is not
adjusted properly.
. When strong light enters the lane
camera unit. (For example, the light
directly shines on the front of the
vehicle at sunrise or sunset.)
. When a sudden change in brightness
occurs. (For example, when the vehicle
enters or exits a tunnel or under a
bridge.)

Side indicator light
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detect vehicles in the detection
zone, the side indicator light illuminates. If
the driver then activates the turn signal, a
chime will sound twice and the side
indicator light will flash.
The BSI system operates above approxi-
mately 37 MPH (60 km/h). If the system
detects a vehicle in the detection zone and
your vehicle is approaching the lane
marker, the BSI system provides an audi-
ble warning (three times), flashes the side
indicator light and slightly applies the
steering for a short period of time to help return the vehicle back to the traveling
lane. The BSI system provides an audible
warning and turns on or flashes the side
indicator light even if the BSW system is
off.
WARNING
.
The BSW and BSI systems are not a
replacement for proper driving procedure
and are not designed to prevent contact
with vehicles or objects. When changing
lanes, always use the side and rear
mirrors and turn and look in the direc-
tion you will move to ensure it is safe to
change lanes. Never rely solely on the
BSW or BSI system.
. Using the BSI system under some road,
lane marker or weather conditions could
lead to improper system operation. Al-
ways rely on your own steering and
braking operation to avoid accidents.
. The BSW and BSI systems may not
provide a warning or steering control
for vehicles that pass through the
detection zone quickly.

Side indicator light
BSW system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If the turn signal is
then activated, the side indicator light
flashes and a chime sounds twice. The
side indicator light continues to flash until
the detected vehicles leave the detection
zone.
The side indicator lights illuminate for a
few seconds when the ignition switch is
placed in the ON position.

The brightness of the side indicator lights
is adjusted automatically depending on the
brightness of the ambient light.
A chime sounds if the radar sensors have
already detected vehicles when the driver
activates the turn signal. If a vehicle comes
into the detection zone after the driver
activates the turn signal, then only the side
indicator light flashes and no chime
sounds. (See“BSW/BSI driving situations”
(P.5-43).)

BSI system operation
If the radar sensors detect vehicles in the
detection zone, the side indicator light
located inside the vehicle (near the outside
mirrors) illuminates. If your vehicle is
approaching a lane marker, the side
indicator light flashes and an audible
warning will sound three times. Then the
system applies the steering for a short
period of time to help return the vehicle
back to the center of the lane. BSI operates
regardless of turn signal usage.NOTE:
.
Warning and steering control will only
be activated if the side indicator light
is already illuminated when your vehi-
cle approaches a lane marker. If
another vehicle comes into the detec-
tion zone after your vehicle has
crossed a lane marker, no warning or
steering control will be activated. (See
“BSW/BSI driving situations” (P.5-43).)
. The BSI system is typically activated
earlier than the Lane Departure Pre-
vention (LDP) system when your vehi-
cle is approaching a lane marker.
