warning light INFINITI M 2011 Repair Manual

The Lane Departure Warning (LDW)
system/Lane Departure Prevention (LDP) sys-
tem will operate when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above, and when it is traveling close to either
the left or the right of a traveling lane.
Each system functions as follows:
●Lane Departure Warning (LDW) system —
warns the driver by a warning light and
chime.
● Lane Departure Prevention (LDP) system —
warns the driver by a warning light and
chime, and helps assist the driver to return
the vehicle to the center direction of the
traveling lane by applying brake control to
the left or right wheels individually (for a
short period of time). 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 lane departure warning
light
2on the instrument panel blinks in
orange and a warning chime sounds. When the
LDP system is on, it will automatically apply the
brakes for a short period of time, using the
function of the Vehicle Dynamic Control (VDC)
system.

LANE DEPARTURE WARNING (LDW)
SYSTEM
Precautions on LDW system
WARNING
●This system is only a warning device to in-
form the driver of a potential unintended
lane departure. It will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility 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 or if it cannot detect
lane markers.
● If the LDW system malfunctions, it will can-
cel automatically, and the lane departure
warning light (orange) will illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the lane departure
warning light (orange) continues to illumi-
nate, have the system checked by an INFINITI
retailer. ●
Excessive noise will interfere with the warn-
ing 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-standard lane markers; or lane
markers covered with water, dirt, snow, etc.
● On roads where the discontinued lane mark-
ers are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,
wheel ruts, seams or lines remaining after
road repairs. (The 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.)

LDW system operation
The LDW system provides a lane departure
warning function when the vehicle is driven at
speeds of approximately 45 MPH (70 km/h) and
above. When the vehicle approaches either the
left or the right side of the traveling lane, a
warning chime will sound and the lane depar-
ture warning light (orange) on the instrument
panel will blink to alert the driver.
The warning function will stop when the vehicle
returns inside of the lane markers.
The LDW system is not designed to warn under
the following conditions.
– When you operate the lane change signaland change traveling lanes in the direction of
the signal. (The LDW system will become
operable again approximately 2 seconds af-
ter the lane change signal is turned off.)
– When the vehicle speed lowers to less than approximately 45 MPH (70 km/h).
– When the BSI system activates an audible warning or brake control.
After the above conditions have finished and
the necessary operating conditions are satis-
fied, the LDW functions will resume.
The LDW system is automatically turned on
when the engine is started and the warning systems ON indicator
1illuminates on the
switch. You can turn the LDW system off by
pushing the warning systems switch on the
instrument panel. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
Temporary disabled status at high
temperature
If the vehicle is parked in direct sunlight under
high temperature conditions (over approxi-
mately 104°F (40°C) and then started, the LDW
system may be deactivated automatically. The
lane departure warning light (orange) will flash.
When the interior temperature is reduced, the
LDW system will resume operating automati-
cally and the lane departure warning light (or-
ange) will stop flashing.

LANE DEPARTURE PREVENTION (LDP)
SYSTEM
Precautions on LDP system
WARNING
●The LDP system will not steer the vehicle or
prevent loss of control. It is the driver’s re-
sponsibility to stay alert, drive safely, keep
the vehicle in the traveling lane, and be in
control of vehicle at all times.
● The LDP system is primarily intended for use
on well-developed freeways or highways. It
may not detect the lane markers in certain
roads, weather or driving conditions.
● Using the LDP system under some condi-
tions of road, lane marker or weather, or
when you change lanes without using the
lane change signal could lead to an unex-
pected system operation. In such condi-
tions, you need to correct the vehicle’s direc-
tion with your steering operation to avoid
accidents.
● When the LDP system is operating, avoid
excessive or sudden steering maneuvers.
Otherwise, you could lose control of the
vehicle. ●
The LDP system will not operate at speeds
below approximately 45 MPH (70 km/h) or if
it cannot detect lane markers.
● The LDP system may not function properly
under the following conditions, and do not
use the LDP system:
– During bad weather (rain, fog, snow, wind, etc.).
– When driving on slippery roads, such as on ice or snow, etc.
– When driving on winding or uneven roads.
– When there is a lane closure due to road repairs.
– When driving in a makeshift lane.
– When driving on roads where the lane width is too narrow.
– When driving with a tire that is not 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 suspension parts. ●
If the LDP system malfunctions, it will cancel
automatically. The lane departure warning
light (orange) on the instrument panel will
illuminate.
● If the lane departure warning light (orange)
illuminates, pull off the road to a safe loca-
tion and stop the vehicle. Turn the engine off
and restart the engine. If the warning light
(orange) continues to illuminate, have the
LDP system checked by an INFINITI retailer.
● Excessive noise will interfere with the warn-
ing chime sound, and the chime may not be
heard.
The functions of the LDP system (warning and
brake control assist) may or may not operate
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-standard lane markers; lane
markers covered with water, dirt, snow, etc.
● On roads where discontinued lane markers
are still detectable.
● On roads where there are sharp curves.
● On roads where there are sharply contrast-
ing objects, such as shadows, snow, water,

● 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.)
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.
LDP system operation
The LDP system provides a lane departure warn-
ing and brake control assistance when the
vehicle is driven at speeds of approximately 45
MPH (70 km/h) and above. When the vehicle
approaches either the left or the right side of
the traveling lane, a warning chime will sound
and the lane departure warning light (orange)
on the instrument panel will blink to alert the
driver. Then, the LDP system will automatically
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. The warning and assist functions will stop when
the vehicle returns to a position inside of the
lane marker.

keep the proper operation of the LDW/LDP
systems and prevent a system malfunction, be
sure to observe the following:
● Always keep the windshield clean.
● Do not attach a sticker (including transpar-
ent material) or install an accessory near the
camera unit.
● Do not place reflective materials, such as
white paper or a mirror, on the instrument
panel. The reflection of sunlight may ad-
versely affect the camera unit’s capability of
detecting the lane markers. ●
Do not strike or damage the areas around
the camera unit. Do not touch the camera
lens or remove the screw located on the
camera unit. If the camera unit is damaged
due to an accident, contact an INFINITI re-
tailer.

The BSW and BSI systems can help alert the
driver of other vehicles in adjacent lanes when
changing lanes.The BSW system uses radar sensors
1in-
stalled near the rear bumper to detect other
vehicles beside your vehicle in an adjacent
lane. In addition to the radar sensors, the BSI
system uses a camera
2installed behind the
windshield to monitor the lane markers of your
traveling lane. The radar sensors can detect vehicles on either
side of your vehicle within the detection zone
shown as illustrated. This detection zone starts
from the outside mirror of your vehicle and
extends approximately 10 ft (3.0 m) behind the
rear bumper, and approximately 10 ft (3.0 m)
sideways.
The BSW system operates above approximately
20 MPH (32 km/h). If the radar sensors
detect
a vehicle in the detection zone, the BSW/BSI
indicator light illuminates. If the driver then
activates the turn signal, a chime will sound
twice and the BSW/BSI indicator light will flash.

The BSI system operates above approximately
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
issues an audible warning (three times), flashes
the BSW/BSI indicator light and slightly applies
the brakes for a short period of time on one side
to help return the vehicle back to the traveling
lane. Whenever the BSI system is turned on, the
BSW system will also be on.
WARNING
●The BSW and BSI systems are not a replace-
ment for proper driving procedure and is 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 direction 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. Always rely on
your own steering and braking operation to
avoid accidents.
● The BSW and BSI systems may not provide a
warning or brake control for vehicles that
pass through the detection zone quickly.
BSW SYSTEM OPERATION
If the radar sensors detect a vehicle in the
detection zone, the BSW/BSI indicator light
next to the outside mirror will illuminate in the
direction of the detected vehicle. If the turn
signal is then activated, the BSW/BSI indicator
light flashes and a chime sounds twice. The
indicator light continues to flash until the de-
tected vehicle leaves the detection zone.
The BSW/BSI indicator lights illuminate for a
few seconds when the ignition switch is pushed
to the ON position.

The brightness of the BSW/BSI 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 acti-
vates the turn signal. If a vehicle comes into the
detection zone after the driver activates the turn
signal, then only the BSW/BSI indicator light
flashes and no chime sounds. (See “BSW/BSI
DRIVING SITUATIONS” later in this section)
The BSW system is automatically turned on
when the engine is started and the warning
systems ON indicator
1illuminates on the
switch. You can turn the BSW system off by
pushing the warning systems switch on the
instrumental panel. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
NOTE:
If you continue to push the warning systems
switch from off to on for over 4 seconds, a chime
will sound. This will change the default status of
the LDW, BSW and FCW systems to OFF so that
these systems will not automatically turn on
when the engine is started. If this procedure is
repeated, the default status will return to ON.
BSI SYSTEM OPERATION
If the BSW/BSI indicator light is illuminated
while your vehicle is approaching a lane
marker, the BSW/BSI indicator light flashes and
an audible warning will sound three times. Then
the system applies the brakes on one side of
the vehicle 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 brake control will only be acti-
vated if the BSW/BSI indicator light is al-
ready illuminated when your vehicle ap-
proaches a lane marker. If another vehicle
comes into the detection zone after your ve-
hicle has crossed a lane marker, no warning
or brake control will be activated. (See
“BSW/BSI DRIVING SITUATIONS” later in this
section.)
● The BSI system is typically activated earlier
than the LDP system when your vehicle is
approaching a lane marker.
The BSI system is turned on if you push the
dynamic driver assistance switch on the steer-
ing wheel after starting the engine. The BSI ON
indicator light (green) on the instrument panel
will illuminate. Push the dynamic driver assis-
