System operation
WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically
accelerates or decelerates your vehicle
according to the speed of the vehicle ahead.
Depress the accelerator to properly accel-
erate your vehicle when acceleration is
required for a lane change. Depress the brake pedal when deceleration is required to
maintain a safe distance to the vehicle
ahead due to its sudden braking or if a
vehicle cuts in. Always stay alert when
using the ICC system.
The driver sets the desired vehicle speed
based on the road conditions. The ICC
system maintains the set vehicle speed,
similar to standard cruise control, as long
as no vehicle is detected in the lane ahead.
The ICC system displays the set speed.Vehicle detected ahead:
When a vehicle is detected in the lane
ahead, the ICC system decelerates the
vehicle by controlling the throttle and
applying the brakes to match the speed
of a slower vehicle ahead. The system then
controls the vehicle speed based on the
speed of the vehicle ahead to maintain the
driver selected distance.
The stoplights of the vehicle come on
when braking is performed by the ICC
system.
When the brake operates, a noise may be
heard. This is not a malfunction.
When a vehicle ahead is detected, the
vehicle ahead detection indicator comes
on. The ICC system will also display the set
speed and selected distance.
Vehicle ahead not detected:
When a vehicle is no longer detected
ahead, the ICC system gradually acceler-
ates your vehicle to resume the previously
set vehicle speed. The ICC system then
maintains the set speed.
When a vehicle is no longer detected the
vehicle ahead detection indicator turns off.
If a vehicle ahead appears during accel-
eration to the set vehicle speed or any time

5-86Starting and driving
When a vehicle ahead is detected:
The vehicle ahead detection indicator
comes on.
When the vehicle approaches a vehicle
ahead:
.If the driver’ s foot is not on the
accelerator pedal, the system activates
the brakes to decelerate smoothly as
necessary. If the vehicle ahead comes
to a stop, the vehicle decelerates to a
standstill within the limitations of the
system.
. If the driver’s foot is on the accelerator
pedal, the system moves the accelera-
tor pedal upward to assist the driver to
release the accelerator pedal.
When brake operation by driver is re-
quired:
The system alerts the driver by a warning
chime and blinking the vehicle ahead
detection indicator. If the driver’s foot is
on the accelerator pedal after the warning,
the system moves the accelerator pedal
upward to assist the driver to switch to the
brake pedal. The stoplights of the vehicle come on
when braking is performed by the DCA
system.
When the brake operates, a noise may be
heard. This is not a malfunction.
WARNING
.
When the vehicle ahead detection in-
dicator is not illuminated, system will
not control or warn the driver.
. 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 (ICC)
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.

1. Driver assist system forward indicator
2. Vehicle ahead detection indicator
SYSTEM OPERATION
The forward emergency braking system will
function when your vehicle is driven at
speeds above approximately 3 MPH (5
km/h).
If a risk of a forward collision is detected,
the forward emergency braking system will
provide the first warning to the driver by
flashing the driver assist system forward
indicator (orange) and the vehicle ahead
detection indicator (orange), and providing
an audible warning. In addition, theforward emergency braking system pushes
the accelerator pedal up. If the driver
releases the accelerator pedal, then the
system applies partial braking.
If the driver applies the brakes quickly and
forcefully after the warning, and the
forward emergency braking system detects
that there is still the possibility of a
forward collision, the system will automa-
tically increase the braking force.
If a forward collision is imminent and the
driver does not take action, the forward
emergency braking system issues the
second visual (red) and audible warning
and automatically applies harder braking.NOTE:
The vehicle’s stop lights come on when
braking is performed by the forward
emergency braking system.
Depending on vehicle speed and distance
to the vehicle ahead, as well as driving and
roadway conditions, the system may help
the driver avoid a forward collision or may
help mitigate the consequences if a colli-
sion should one be unavoidable.
If the driver is handling the steering wheel,
accelerating or braking, the forward emer-
gency braking system will function later or
will not function.
The automatic braking will cease under the
following conditions:
.
When the steering wheel is turned as
far as necessary to avoid a collision.
. When the accelerator pedal is de-
pressed.
. When there is no longer a vehicle
detected ahead.
If the forward emergency braking system
has stopped the vehicle, the vehicle will
remain at a standstill for approximately 2
seconds before the brakes are released.

DIRECT ADAPTIVE STEERING TYPE
WARNING
When the power steering warning light
illuminates with the INFINITI Direct Re-
sponse Hybrid
®System running, the power
assist for the steering will cease operation.
You will still have control of the vehicle, but
the steering will be harder to operate.
CAUTION
. If wheels or tires other than the INFINITI
recommended ones are used, the direct
adaptive steering system may not oper-
ate properly and the power steering
warning light may illuminate.
. Do not modify the vehicle’s suspension.
If suspension parts such as shock
absorbers, struts, springs, stabilizer
bars, bushings and wheels are not
INFINITI recommended for your vehicle
or are extremely deteriorated, the direct
adaptive steering system may not oper-
ate properly and the power steering
warning light may illuminate. .
Do not modify the vehicle’s steering. If
steering parts are not INFINITI recom-
mended for your vehicle or are extremely
deteriorated, the direct adaptive steer-
ing system may not operate properly and
the power steering warning light may
illuminate.
. If the VDC warning light illuminates, the
power steering warning light may also
illuminate at the same time. Stop the
vehicle in a safe location, turn the hybrid
system off and restart the hybrid sys-
tem. If the power steering warning light
continues to illuminate, have the system
checked by an INFNITI retailer. For the
VDC system, see “Vehicle Dynamic Con-
trol (VDC) system” (P.5-108).
. Do not place the ignition switch is in the
ON position while the steering wheel or
a tire is removed.
. Do not turn the steering wheel as much
as possible while the ignition switch is
in any position other than the ON
position.
. Installing an accessory on the steering
wheel, or changing the steering wheel,
may reduce the steering performance.
The direct adaptive steering system is
designed to control the steering force and
steering angle according to the vehicle
speed and amount of turning of the
steering wheel.
The steering characteristic can be selected
with the INFINITI Drive Mode Selector. See
“INFINITI Drive Mode Selector” (P.5-21).
When the steering wheel is operated
repeatedly or continuously while parking
or driving at a very low speed, the power
assist for the steering wheel will be
reduced and the steering wheel may be
slightly turned even when driving on a
straight road. This is to prevent overheat-
ing of the direct adaptive steering system
and protect it from getting damaged. When
the temperature of the direct adaptive
steering system cools down, the power
assist level will return to normal. Avoid
repeating steering wheel operations that
could cause the direct adaptive steering
system to overheat.
If the power steering warning light illumi-
nates while the hybrid system is running, it
may indicate that the direct adaptive
steering system is not functioning properly
and may need servicing. Have the system
checked by an INFINITI retailer. (See
