2018 INFINITI Q70 brake light

.Lane Departure Warning (LDW) system
— warns the driver with a warning light and chime that the vehicle is begin-
ning to leave the driving lane.
. Lane Departure Prevention (LDP) system
— warns the driver with a warning light and chime, and helps assist the driver
to return the vehicle to the center of
the traveling lane by applying the
brakes to the left or right wheels
individually (for a short period of
time).
JVS0691X
The LDW and LDP systems use a camerainstalled behind the windshield to monitor
the lane markers of your traveling lane.

HOW TO ENABLE/DISABLE THE
LDW SYSTEM
Perform the following steps to enable or
disable the LDW system.
1. Push the SETTING button
.
2. Touch [Driver Assistance].
3. Touch [Lane Assist].
4. Touch [Lane Departure Warning] to turn the system ON/OFF.
LDP SYSTEM OPERATION
The LDP system operates above approxi-
mately 45 MPH (70 km/h) and when the
lane markings are clear.
If the vehicle approaches either the left or
right side of the traveling lane, the LDW
indicator light (orange) on the instrument
panel will flash and a warning chime will
sound. Then, the LDP system will automa-
tically apply the brakes for a short period of
time to help assist the driver to return the
vehicle to the center of the traveling lane.
NOTE:
.The LDP system is not designed to work
when you operate the lane change signal
and change traveling lanes in the direc-
tion of the signal. (The LDP system will
become operable again approximately 2
seconds after the lane change signal is
turned off.)
. The LDP braking assist will not operate
or will stop operating and only a warn-
ing chime will sound under the following
conditions.
— When the brake pedal is depressed.
— When the steering wheel is turned as
far as necessary for the vehicle to
change lanes.
— When the accelerator pedal is de-
pressed while brake control assist is provided.
— When the ICC, DCA, BSI, BSW,
PFCW or FEB warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
. While the LDP system is operating, you
may hear a sound of brake operation.
This is normal and indicates that the
LDP system is operating properly.

BSI SYSTEM OPERATION
The BSI system operates above approxi-
mately 37 MPH (60 km/h).
If the radar sensors detect a vehicle in the
detection zone, the side indicator light
illuminates.
If the turn signal is then activated, the
system chimes (twice) and the side indicator
light flashes. The side indicator light con-
tinues to flash until the detected vehicle
leaves the detection zone.
If the BSI system is ON and your vehicle
approaches a lane marker while another
vehicle is in the detection zone, the system
chimes (three times) and the side indicator
light flashes. Then the BSI system slightly
applies the brakes to help return the vehicle
back to the center of the driving lane. The
BSI system operates regardless of turn
signal usage.
NOTE:
.Warning and system application of the
brakes will only be activated if the side
indicator light is already illuminated
when your vehicle approaches a lane
marker. If another vehicle comes into
the detection zone after your vehicle has
crossed a lane marker, no warning or
system application of the brakes will be
activated. (See “BSI driving situations”

— When driving with a tire that isnot within normal tire conditions
(for example, tire wear, low tire
pressure, installation of spare tire,
tire chains, non-standard wheels).
— When the vehicle is equipped with non-original brake parts or sus-
pension parts.
. Excessive noise (for example, audio
system volume, open vehicle window)
will interfere with the chime sound,
and it may not be heard.

indicator light flashes. Then the BSI system
slightly applies the brakes to help return the

NOTE:
. The radar sensors may not detect vehi-
cles which are approaching rapidly from
behind.
. If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the other vehicle is detected.

Illustration 6: If the BSI system is on and your
vehicle approaches a lane marker while
another vehicle is in the detection zone, the
system chimes (three times) and the side
indicator light flashes. Then, the BSI system
slightly applies the brakes on the appropriate
side to help return the vehicle back to the
center of the driving lane.
NOTE:
. When overtaking several vehicles in a
row, the vehicles after the first vehicle
may not be detected if they are travel-
ing close together.
. The radar sensors may not detect slower
moving vehicles if they are passed quickly.
. If the driver activates the turn signal
before a vehicle enters the detection
zone, the side indicator light will flash
but no chime will sound when the other
vehicle is detected.

Illustration 10: The BSI system will not
operate if your vehicle is on a lane marker
when another vehicle enters the detection

same speed as your vehicle when it
enters the detection zone.
