warning light INFINITI EX 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 (72 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 with a warning light and
chime that the vehicle is beginning to leave
the driving lane.
● 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 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 inside the front map light cover.
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 (70 km/h) or if it can-
not 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.)
5-18Starting and driving

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.
When you operate the lane change signal and
change traveling lanes in the direction of the
signal, the LDW system temporarily suspends
operation. It will become operable again ap-
proximately 2 seconds after the lane change
signal is turned off.
When the vehicle speed lowers to less than
approximately 45 MPH (70 km/h), the LDW
system will not provide a warning.
The LDW system has an automatic setting mode
and a manual setting mode. The setting mode
can be changed. In the automatic setting mode,
the LDW system is automatically turned on
when the ignition switch is pushed to the ON
position. When the LDW system is on, the
warning systems ON indicator
1on the warn-
ing systems switch illuminates. To cancel the LDW system, push the warning systems switch.
The warning systems ON indicator will turn off.
To turn on the system, push the warning sys-
tems switch again. This switch will turn on and
off the LDW, BSW and FCW systems at the same
time.
In the manual setting mode, you need to push
the warning systems switch to turn on the
system after the ignition switch is pushed to the
ON position.
The setting mode can be changed using the
warning systems switch. To change the setting
mode, push and hold the warning systems
switch for more than 4 seconds when the
warning systems ON indicator is off. When the
mode is changed, a chime sounds and the lane
departure warning light (orange) flashes.
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) on the
switch will flash.

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 without normal tire condi- tions (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; or lane
markers covered with water, dirt, snow, etc.
● On roads where discontinued lane markers
are still detectable.
● On roads where there are sharp curves.

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.

The Blind Spot Warning (BSW) system can help
alert the driver of other vehicles in adjacent
lanes when changing lanes.The BSW system uses radar sensors
Ain-
stalled near the rear bumper to detect other
vehicles beside your vehicle in an adjacent
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 indicator
light illuminates. If the driver then activates the
turn signal, a chime will sound twice and the
BSW indicator light will flash.

BLIND SPOT WARNING (BSW) SYSTEM (if
so equipped)
Starting and driving5-25

WARNING
●The BSW system is not a replacement for
proper driving procedure and is not de-
signed 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 system.
● The BSW system may not provide a warning
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 indicator light next to
the outside mirror will illuminate in the direc-
tion of the detected vehicle. If the turn signal is
then activated, the BSW indicator light flashes
and a chime sounds twice. The indicator light
continues to flash until the detected vehicle
leaves the detection zone.
The BSW indicator lights illuminate for a few
seconds when the ignition switch is pushed to
the ON position.

5-26Starting and driving

The brightness of the BSW 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 indicator light flashes
and no chime sounds. (See “BSW DRIVING
SITUATIONS” later in this section)
The BSW system is automatically turned on
when the engine is started and the warning
systems ON indicator light
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.
WARNING
● Do not use the BSW system when towing a
trailer because the system may not function
properly.
● Excessive noise (e.g. audio system volume,
open vehicle window) will interfere with the
chime sound, and it may not be heard.
● The radar sensors may not be able to detect
and activate BSW when certain objects are
present such as:
– Pedestrians, bicycles, animals
– Several types of vehicles such as motor- cycles
– Oncoming vehicles
– Vehicles remaining in the detection zone when you accelerate from a stop
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle merging into an adjacent lane at a speed approximately the same as your
vehicle
(See “BSW DRIVING SITUATIONS” later in
this section) – A vehicle approaching rapidly from be-
hind.
(See “BSW DRIVING SITUATIONS” later in
this section)
– A vehicle which your vehicle overtakes rapidly.
(See “BSW DRIVING SITUATIONS” later in
this section)
● Severe weather or road spray conditions
may reduce the ability of the radar to detect
other vehicles.
● The radar sensors detection zone is de-
signed based on a standard lane width.
When driving in a wider lane, the radar
sensors may not detect vehicles in an adja-
cent lane. When driving in a narrow lane, the
radar sensors may detect vehicles driving
two lanes away.
● The radar sensors are designed to ignore
most stationary objects, however objects
such as guardrails, walls, foliage and parked
vehicles may occasionally be detected. This
is a normal operating condition.
Starting and driving5-27

If the driver activates the turn signal, then the
BSW indicator light flashes and a chime will
sound twice.
NOTE:
If the driver activates the turn signal before a
vehicle enters the detection zone, the BSW indi-
cator light will flash but no chime will sound
when another vehicle is detected.
BSW temporarily not available
●When radar blockage is detected, the BSW
system will be turned off automatically, a
beep will sound and the BSW system warn- ing light (orange) will blink. The BSW system
is not available until the condition no longer
exists.
The radar sensors may be blocked by temporary
ambient conditions such as splashing water,
mist or fog. The blocked condition may also be
caused by objects such as ice, frost or dirt
obstructing the radar sensors.
Action to take:
When the above condition no longer exists, the
BSW system will resume automatically.
If the warning light (orange) continues to blink,
have the BSW system checked by an INFINITI
retailer.
BSW MALFUNCTION
When the BSW system malfunctions, they will
be turned off automatically, a beep will sound
and the BSW system warning light (orange) will
illuminate.
Action to take:
Stop the vehicle in a safe location, turn the
engine off and restart the engine.
If the warning light (orange) continues to illu-
minate, have the BSW system checked by an
INFINITI retailer.
SYSTEM MAINTENANCE
The two radar sensor unitsAfor the BSW
system are located near the rear bumper. Al-
ways keep the area near the radar sensors
clean. Do not attach stickers (including trans-
parent material), install accessories or apply
additional paint near the radar sensors. Do not
strike or damage the area around the radar
sensors. Consult an INFINITI retailer if the area
around the radar sensors is damaged due to a
collision.
