Warning light
When the system is not operating properly,
the chime sounds and the system warning
light (orange) will come on.
Action to take:
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine, resume driving and then
perform the setting again.
If it is not possible to set or the indicator
stays on, it may indicate that the system is
malfunctioning. Although the vehicle is
still driveable under normal conditions,
have the vehicle checked at an INFINITI retailer.
PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function
identifies the need to apply emergency
braking by sensing the vehicle ahead in
the same lane and the distance to the
vehicle ahead and relative speed from it, it
applies the brake pre-pressure before the
driver depresses the brake pedal and helps
improve brake response by reducing pedal
free play.

WARNING
.When the vehicle ahead detection in-
dicator light is not illuminated, system
will not control or warn the driver.
. Never place your foot under the brake
pedal. Your foot may be caught when the
system controls the brake.
. Depending on the position of the accel-
erator pedal, the system may not be able
to assist the driver to release the
accelerator pedal appropriately.
. If the vehicle ahead comes to a stand-
still, the vehicle decelerates to a stand-
still within the limitations of the system.
The system will release brake control
with a warning chime once it judges the
vehicle is at a standstill. To prevent the
vehicle from moving, the driver must
depress the brake pedal. (The system
will resume control automatically once
the system reaches 3 MPH (5 km/h)).
Overriding the system:
The following driver’s operation overrides
the system operation. .
When the driver depresses the accel-
erator pedal even further while the
system is moving the accelerator pedal
upward, the DCA system control of the
accelerator pedal is canceled.
. When the driver’s foot is on the accel-
erator pedal, the brake control by the
system is not operated.
. When the driver’s foot is on the brake
pedal, neither the brake control nor the
alert by the system operates.
. When the Intelligent Cruise Control
system is set, the DCA system will be
cancelled.
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 vehi-
cles is increasing
. 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.

conditions, have the vehicle checked at an
INFINITI retailer.
Sensor maintenance
How to handle the sensor:
The sensor for the DCA system is common
with Intelligent Cruise Control and is
located below the front bumper.
To handle the sensor, see“Intelligent
Cruise Control (ICC) system (FULL SPEED
RANGE)” earlier in this section. The Forward Collision Warning (FCW) sys-
tem will warn the driver by a warning light
and chime when your vehicle is getting
close to the vehicle ahead in the traveling
lane.
The FCW system will function when your
vehicle is driven at speeds of approxi-
mately 10 MPH (15 km/h) and above.

FCW system operation
The FCW system will function at speeds of
approximately 10 MPH (15 km/h) and
above, when the system turns on.
The FCW system has an automatic setting
mode and a manual setting mode to turn
the system on. The setting mode can be
changed. In the automatic setting mode,
the FCW system is automatically turned on
when the ignition switch is pushed to the
ON position. When the FCW system is on,
the warning systems ON indicator light
*1
on the warning systems switch illuminates.
To cancel the FCW system, push thewarning systems switch. The warning
systems ON indicator light will turn off. To
turn on the system, push the warning
systems switch again.
When the warning systems switch is
pushed, the LDW and BSW systems will
also turn on or off simultaneously. See
“Lane Departure Warning (LDW) system”
earlier in this section and
“Blind Spot
Warning (BSW) system” earlier in this
section.
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.
For the sensor maintenance, see “Intelli-
gent Cruise Control (ICC) system (FULL
SPEED RANGE)” earlier in this section. 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
collision cannot be prevented.
The IBA system will function when your
vehicle is driven at speeds of approxi-
mately 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.

pushed again, the system will turn on and
the IBA OFF indicator light will turn off.
The IBA system will remain in the last ON
or OFF state it was left in until it is
manually changed by pressing the IBA
OFF switch.
Illumination of the IBA OFF indicator light
without the warning chime sound is an
indication that the IBA system is tempora-
rily unavailable. It will occur under the
following conditions:
.When driving into a strong light (for
example, sunlight)
The IBA OFF indicator light will turn off
when the system returns to its normal
operating conditions.

CAUTION
During the first 1,200 miles (2,000 km),
follow these recommendations to obtain
maximum engine performance and ensure
the future reliability and economy of your
new vehicle.
Failure to follow these recommendations
may result in shortened engine life and
reduced engine performance.
.Avoid driving for long periods at con-
stant speed, either fast or slow. 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 possi-
ble. .
Accelerate slowly and smoothly. Main-
tain cruising speeds with a constant
accelerator position.
. Drive at moderate speeds on the high-
way.
. Avoid unnecessary stopping and brak-
ing. Keep a safe distance behind other
vehicles.
. Select a gear range suitable to road
conditions.
. Avoid unnecessary prolonged engine
idling.
. Keep your engine tuned up.
. Follow the recommended periodic main-
tenance schedule.
. Keep the tires inflated at the correct
pressure. Improper tire pressure will
increase wear and waste fuel.
. Make sure the front wheels are properly
aligned. Improper alignment will cause
premature tire wear and lower fuel
economy.
. Climate control operation lowers fuel
economy. Use the air conditioner only
when necessary.
. When cruising at highway speeds, it is
more economical to use the air condi-
tioner and leave the windows closed to
reduce drag.
BREAK-IN SCHEDULE INCREASING FUEL ECONOMY

5-82Starting and driving
during braking.
To dry brakes, drive the vehicle at a safe
speed while lightly tapping the brake pedal
to heat-up the brakes. Do this until the
brakes return to normal. Avoid driving the
vehicle at high speeds until the brakes
function correctly.
PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever
the stopping effect of the parking brake is
weakened or whenever the parking brake
shoes and/or drums/rotors are replaced,
in order to assure the best braking
performance.
This procedure is described in the vehicle
service manual and can be performed by
an INFINITI retailer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating
of the brakes, wearing out the brake and
pads faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed
and downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performanceand could result in loss of vehicle control.
WARNING
.
While driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
. If the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional 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
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at all
times.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models)
When the Preview Function identifies the
need to apply emergency braking by
sensing a vehicle ahead in the same lane
and the distance and relative speed from
it, it applies the brake pre-pressure before
the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play.
