2013 INFINITI JX brake sensor

Approach warning
If your vehicle comes closer to the vehicle ahead
due to rapid deceleration of that vehicle or if
another vehicle cuts in, the system warns the
driver with the chime and DCA system display.
Decelerate by depressing the brake pedal to
maintain a safe vehicle distance if:● The chime sounds.
● The vehicle ahead detection indicator blinks.
The warning chime may not sound in some cases
when there is a short distance between vehicles.
Some examples are: ● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
The warning chime will not sound when your
vehicle approaches vehicles that are parked or
moving slowly. NOTE:
The approach warning chime may sound
and the system display may blink when ICC
sensor detects vehicles in other lanes
Aor
objects on the side of the road
A. This may
cause the DCA system to operate inappro-
priately. The ICC sensor may detect these
objects when the vehicle is driven on wind-
ing roads, narrow roads, hilly roads or when
entering or exiting a curve. In these cases
you will have to manually control the
proper distance ahead of your vehicle. Also, the sensor sensitivity can be affected by
vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condition
(for example, if a vehicle is being driven with some
damage) .
Automatic cancellation
Condition A:
Under the following conditions, the Distance
Control Assist system is automatically canceled.
The chime will sound and the Distance Control
Assist (DCA) cancellation message will pop up.

The Intelligent Brake Assist (IBA) system warns
the driver by a warning light and chime when
there is a risk of a collision with the vehicle ahead
in the traveling lane and the driver must take
avoidance action immediately. The system helps
reduce the rear-end collision speed by applying
the brakes when the system judges that the col-
lision cannot be prevented.
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) and above, and when your vehicle is
driven at speeds approximately 10 MPH
(15 km/h) faster than the vehicle ahead.The IBA system uses a distance sensor
Alo-
cated behind the front bumper to measure the
distance to the vehicle ahead. When the system
judges that your vehicle is getting close to the
vehicle ahead in the traveling lane, the vehicle
ahead detection indicator light on the information
display blinks and a warning chime sounds.
The IBA system will be turned on/off by in the
settings of the vehicle information display, see
“Driving aids” in the “Instrument and controls”
section.

●The system will be cancelled automati-
cally with a beep sound and the IBA
warning light will illuminate under the
following conditions:
– When the sensor area of the front bumper is dirty
– When the system malfunctions
If the IBA OFF indicator light illuminates with a
beep sound, pull off the road to a safe location,
stop the vehicle and turn the engine off. Check to
see if the sensor area of the front bumper is dirty.
If the sensor area of the front bumper is dirty,
clean it with a soft cloth and restart the engine. If
the sensor window is not dirty, restart the engine.
If the IBA OFF indicator light continues to illumi-
nate even if the IBA system is turned on, have the
system checked by an INFINITI retailer.
IBA SYSTEM OPERATION
The IBA system will function when your vehicle is
driven at speeds of approximately 10 MPH
(15 km/h) or above, and when the vehicle’s
speed is approximately 10 MPH (15 km/h) faster
than that of the vehicle ahead.
To turn the system on/off:
1. Push the
button to enter the “Set-
tings” menu in the vehicle information dis-
play, then select using the ENTER button. 2. Use the
buttons to select “Driver As-
sistance”, then press the ENTER button.
3. Use the
buttons to select “Intelligent
Brake Assist”, using the ENTER button the
system can be turned On or Off.
The IBA system will remain in the last ON or OFF
state it was left in until it is changed in the vehicle
information display, see “Driver Assistance” in the
“Instrument and controls” section.
Illumination of the IBA OFF indicator light without
the warning chime sound is an indication that the
IBA system is temporarily unavailable. It will occur
under the following conditions:
When the radar signal is temporarily interrupted.
The IBA OFF indicator light will turn off when the
system returns to its normal operating conditions.
For the sensor maintenance, see “Intelligent
Cruise Control (ICC) system (Full speed range)”.
CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
● Avoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.
● Do not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged.
BREAK-IN SCHEDULE
5-84Starting and driving

WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and a computer. The
computer has a built-in diagnostic feature that
tests the system each time you start the engine
and move the vehicle at a low speed in forward or
reverse. When the self-test occurs, you may hear
a “clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by an INFINITI retailer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h). The speed varies according to road
conditions.When the ABS senses that 1 or more wheels are
close to locking up, the actuator rapidly applies
and releases hydraulic pressure. This action is
similar to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal and hear a
noise from under the hood or feel a vibration from
the actuator when it is operating. This is normal
and indicates that the ABS is operating properly.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.
BRAKE ASSIST (if so equipped)
When the force applied to the brake pedal ex-
ceeds a certain level, the brake assist is activated
generating greater braking force than a conven-
tional brake booster even with light pedal force.
WARNING
The brake assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. it is the driv-
ers responsibility to stay alert, drive safely
and be in control of the vehicle at all
times.
The Vehicle Dynamic Control (VDC) system uses
various sensors to monitor driver inputs and ve-
hicle motion. Under certain driving conditions,
the VDC System helps to perform the following
functions:
● Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
● Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
● Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following condi-
tions:
– understeer (vehicle tends to not follow the steered path despite increased steer-
ing input)
– oversteer (vehicle tends to spin due to certain road or driving conditions)
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss of
vehicle control in all driving situations.

●When a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon
as possible for tire replacement and/or
system resetting.
● Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
● Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure
sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions be-
low:
Stopping the vehicle
1. Safely move the vehicle off the road and
away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift selector to P (Park) . 4. Turn off the engine.
5. Raise the hood to warn other traffic and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle and stand in a safe place, away from traffic
and clear of the vehicle.
WARNING
●Make sure the parking brake is securely
applied and the automatic transmission
is shifted into P (Park) .
● Never change tires when the vehicle is
on a slope, ice or slippery areas. This is
hazardous.
● Never change tires if oncoming traffic is
close to your vehicle. Wait for profes-
sional road assistance.
Blocking wheels
Place suitable blocks1at both the front and
back of the wheel diagonally opposite the flat tire
2to prevent the vehicle from moving when it is
jacked up.
WARNING
Be sure to block the wheel as the vehicle
may move and result in personal injury.
