2012 INFINITI M brake sensor

2-18Instruments and controls
Check to see if the laser sensor is clean.
Turn the engine off, then restart the
engine.
If the IBA off indicator light illuminates
after following the procedures above, it
may indicate that the system or Active
Trace Control (if so equipped) is malfunc-
tioning. Although the vehicle is still drive-
able under normal conditions, have the
vehicle checked at an INFINITI retailer. (See
“Intelligent Brake Assist (IBA) system ”in
the “5. Starting and driving ”section and
“ Vehicle Dynamic Control (VDC) system ”in
the “5. Starting and driving ”section.)
Lane Departure Prevention
(LDP) ON indicator light (green; if so
equipped)
The light comes on in green when the Lane
Departure Prevention (LDP) system is
turned on. The light turns off when the
system is turned off.
NOTE:
This light is common with the lane
departure warning light (orange). (See
“ Lane departure warning light ”earlier in
this section.)
For more details, see “Lane Departure Warning (LDW) system/Lane Departure
Prevention (LDP) system”
in the“5. Start-
ing and driving ”section.
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks while the engine is
running, it may indicate a potential emis-
sion control malfunction.
The malfunction indicator light may also
come on steady if the fuel-filler cap is loose
or missing, or if the vehicle runs out of fuel.
Check to make sure the fuel-filler cap is
installed and closed tightly, and that the
vehicle has at least 3 US gallons (14 liters)
of fuel in the fuel tank.
After a few driving trips, the
light
should turn off if no other potential
emission control system malfunction ex-
ists.
If this indicator light remains on for 20
seconds and then blinks for 10 seconds
when the engine is not running, it indicates
that the vehicle is not ready for an
emission control system inspection/main-
tenance test. (See “Readiness for Inspec-
tion/Maintenance (I/M) test (US only) ”.) Operation:
The malfunction indicator light will come
on in one of two ways:
.
Malfunction indicator light on steady —
An emission control system malfunc-
tion has been detected. Check the fuel-
filler cap if the LOOSE FUEL CAP
warning appears in the dot matrix
liquid crystal display. If the fuel-filler
cap is loose or missing, tighten or
install the cap and continue to drive the
vehicle. The
light should turn off
after a few driving trips. If the
light
does not turn off after a few driving
trips, have the vehicle inspected by an
INFINITI retailer. You do not need to
have your vehicle towed to the retailer.
. Malfunction indicator light blinking —
An engine misfire has been detected
which may damage the emission con-
trol system.
To reduce or avoid emission control
system damage:
1) Do not drive at speeds above 45 MPH (72 km/h).
2) Avoid hard acceleration or decelera- tion.
3) Avoid steep uphill grades.

The warning systems switch is used to turn
on and off the warning systems (Forward
Collision Warning (FCW), Lane Departure
Warning (LDW) and Blind Spot Warning
(BSW) systems) that are activated using
the settings menu on the center display.
When the warning systems switch is turned
off, the indicator
*1on the switch is off.
The indicator will also be off if all of the
warning systems are deactivated using the
settings menu.
The FCW system will sound a warning
chime and the vehicle ahead detection
indicator light blinks to alert the driver if
the vehicle is traveling close to the vehicle ahead. (See
“Forward Collision Warning
(FCW) system ”in the “5. Starting and
driving ”section.)
The LDW system will sound a warning
chime and blink the lane departure warn-
ing light (orange) to alert the driver if the
vehicle is traveling close to either the left
or the right of a traveling lane with
detectable lane markers. (See “Lane De-
parture Warning (LDW) system/Lane De-
parture Prevention (LDP) system” in the“5.
Starting and driving ”section.)
The BSW system will turn on the BSW/
Blind Spot Intervention (BSI) indicator
lights, located next to the outside mirrors,
if the radar sensors detect a vehicle in the
detection zone. If the turn signal is
activated in the direction of the detected
vehicle, a chime sounds twice and the
BSW/BSI indicator light will flash. (See
“ Blind Spot Warning (BSW) system/Blind
Spot InterventionTM(BSI) system” in the
“ 5. Starting and driving ”section.)
SIC4337
The vehicle should be driven with the
Intelligent Brake Assist (IBA) system on
for most driving conditions.
The Intelligent Brake Assist (IBA) system
will sound a warning chime and the vehicle
ahead detection indicator light blinks to
alert the driver when the vehicle is travel-
ing too close to the vehicle ahead. The
system will also apply the brake control if
necessary.
To turn off the system, push the IBA OFF
switch. The
indicator will illuminate.
The IBA system will remain in the last ON
or OFF state it was left in until it is
manually changed by pushing the IBA OFF

The BSW system uses radar sensors*1
installed 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
*2
installed behind the windshield to monitor
the lane markers of your traveling lane.
SSD1030
Detection zone
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 approxi-
mately 10 ft (3.0 m) behind the rear
bumper, and approximately 10 ft (3.0 m)
sideways.
The BSW system operates above approxi-
mately 20 MPH (32 km/h). If the radar
sensors detects vehicles in the detection
zone, the BSW/BSI indicator light illumi-
nates. 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 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
BSW/BSI indicator light and slightly ap-
plies the brakes for a short period of time
on one side to help return the vehicle back
to the traveling lane. The BSI system
provides an audible warning and turns on
or flashes the BSW/BSI 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 brake control for
vehicles that pass through the detection
zone quickly.
SSD1028
BSW/BSI indicator light
BSW SYSTEM OPERATION
If the radar sensors detect vehicles in the
detection zone, the BSW/BSI indicator
light located inside the outside mirrors
illuminates. 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
detected vehicles leave 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
activates 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.)

BSI SYSTEM OPERATION
If the radar sensors detect vehicles in the
detection zone, the BSW/BSI indicator
light located inside the outside mirrors
illuminates. If 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
activated if the BSW/BSI indicator light
is already illuminated when your vehi-
cle approaches a lane marker. If an-
other vehicle comes into the detection
zone after your vehicle 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 Lane Departure Preven-
tion (LDP) system when your vehicle is
approaching a lane marker.
The BSI system turns on when the dynamic
driver assistance switch on the steering
wheel is pushed when the “Blind Spot
Intervention” is enabled in the settings
menu on the center display. The BSI ON
indicator light (green) on the instrument
panel illuminates when the BSI system is
turned on.
The BSI system provides an audible warn-
ing and flashes the indicator light when
BSI is activated even if the BSW system is
off.

Entering from the side
The BSW/BSI indicator light illuminates if a
vehicle enters the detection zone from
either side.
NOTE:
The radar sensors may not detect a vehicle
which is traveling at about the same speed
as your vehicle when it enters the detec-
tion zone.
SSD1038
If the driver activates the turn signal, then
the BSW/BSI 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/BSI indicator light will flash but
no chime will sound when another vehicle
is detected.
SSD1094
If the BSI system is on and your vehicle
approaches the lane marker while another
vehicle is in the detection zone, the BSW/
BSI indicator light flashes and a chime will
sound three times. Then, the BSI system
slightly applies the brakes on one side to
help return the vehicle back to the center of
the driving lane.

SSD1040
NOTE:
.The BSI system will not operate if your
vehicle is on a lane marker when
another vehicle enters the detection
zone. In this case only the BSW system
operates.
. BSI braking will not operate or will stop
operating and only a warning chime
will sound under the following condi-
tions.
— When the brake pedal is depressed.
— When the accelerator pedal is de-
pressed while brake control assist
is provided. —
When steering quickly
— When the ICC, DCA, FCW or IBA
warnings sound.
— When the hazard warning flashers
are operated.
— When driving on a curve at a high
speed.
BSW/BSI temporarily not available
. Under the following conditions, the BSI
system will be turned off automatically,
a beep will sound and the BSI ON
indicator light (green) will blink. The
BSW system is still available, but the
BSI system will not be available until
the conditions no longer exist.
— When the VDC system (except TCS
function) or ABS operates.
— When the VDC system is turned off.
— When the drive mode select switch
is turned to the SNOW mode.
Action to take:
Turn off the BSI system and turn it on again
when the above conditions no longer exist.
. Under the following conditions, the
BSW and BSI systems will be turned
off automatically, a beep will sound
and the BSW/BSI system warning light (orange) will blink. The BSW and BSI
systems are not available until the
conditions no longer exist.
—
When the camera detects that the
interior temperature is high (over
approximately 104 8F (408 C)).
— When radar blockage is detected.
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 conditions no longer exist,
the BSW system will resume automatically.
For the BSI system, turn it off and turn it on
again. If the BSW/BSI warning light (or-
ange) continues to blink even after the BSI
system is turned on again, stop the vehicle
in a safe location and turn the engine off.
Check for and remove objects obscuring
the radar sensors on the rear bumper, and
restart the engine.
If the warning light (orange) continues to
blink, have the BSW/BSI systems checked
by an INFINITI retailer.
