2014 INFINITI Q70 HYBRID brake sensor

Brake Assist (IBA) system is not operating.
When the IBA off indicator light illuminates
while the system is turned on (without the
warning chime sound), this light indicates
that the system control is temporarily
unavailable.
When the IBA off indicator light illuminates
with the warning chime sound while the
IBA system is turned on, this light indicates
that the system may not be functioning
properly. Park the vehicle in a safe place.
Check to see if the laser sensor is clean.
Stop the hybrid system, then restart the
hybrid system.
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”(P.5-
86) and “Vehicle Dynamic Control (VDC)
system” (P.5-100).)
Lane Departure Warning (LDW)
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 LWD light
(orange). (See
“Lane Departure Warning
(LDW) light” (P.2-14).)
For more details, see “Lane Departure
Warning (LDW) system/Lane Departure
Prevention (LDP) system” (P.5-21).
Malfunction Indicator Light
(MIL)
If the malfunction indicator light comes on
steady or blinks when the ignition switch is
in the ON position, it may indicate a
potential emission 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)” (P.9-
20).)
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 thelight
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.

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” (P.5-82).)
The LDW system will sound a warning
chime and blink the LDW indicator 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 Departure Warning
(LDW) system/Lane Departure Prevention
(LDP) system” (P.5-21).)
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 Intervention
TM(BSI) system” (P.5-31).)
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*1installed 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.
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.

BSW/BSI indicator light
BSW SYSTEM OPERATION
If the radar sensors detect a vehicle in the
detection zone, the BSW/BSI indicator
light located by the outside mirrors illumi-
nates. 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” (P.5-39).)

BSI SYSTEM OPERATION
If the radar sensors detect vehicles in the
detection zone, the BSW/BSI indicator
light located by the outside mirrors illumi-
nates. 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 system application of the
brakes will only be activated if the
BSW/BSI indicator light is already
illuminated when your vehicle ap-
proaches a lane marker. If another
vehicle comes into the detection zone
after your vehicle has crossed a lane
marker, no warning or brake applica-
tion will be activated. (See “BSW/BSI
driving situations” (P.5-39).)
. The BSI system is typically activated
earlier than the Lane Departure Pre-
vention (LDP) system when your vehi-
cle 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 system is activated even if the BSW
system is off.

PRECAUTIONS ON VEHICLE-TO-VE-
HICLE DISTANCE CONTROL MODE
The system is intended to enhance the
operation of the vehicle when following a
vehicle traveling in the same lane and
direction.
If the distance sensor
*Adetects a slower
moving vehicle ahead, the system will
reduce the vehicle speed so that your
vehicle follows the vehicle in front at the
selected distance.
The system automatically controls the
throttle and applies the brakes (up to
25% of vehicle braking power) if neces- sary.
The detection range of the sensor is
approximately 390 ft (120 m) ahead.
WARNING
.
This system is only an aid to assist the
driver and is not a collision warning or
avoidance device. It is the driver’ s
responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
. The system is primarily intended for use
on straight, dry, open roads with light
traffic. It is not advisable to use the
system in city traffic or congested areas.
. This system will not adapt automatically
to road conditions. This system should
be used in evenly flowing traffic. Do not
use the system on roads with sharp
curves, or on icy roads, in heavy rain or
in fog.
The distance sensor will not detect under
most conditions:
.Stationary and slow moving vehicles
. Pedestrians or objects in the roadway .
Oncoming vehicles in the same lane
. Motorcycles traveling offset in the travel
lane
WARNING
. As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Decele-
rate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain a
safe distance between vehicles.
. If the vehicle ahead comes to a stop, the
vehicle decelerates to a standstill within
the limitations of the system. The
system will cancel once it judges that
the vehicle has come to a standstill and
sound a warning chime. To prevent the
vehicle from moving, the driver must
depress the brake pedal.
. The system may not detect the vehicle in
front of you in certain road or weather
