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
approximately 40% of vehicle braking power) if necessary.
The detection range of the sensor is
approximately 650 ft (200 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
(ICC) system. This system does not
correct careless, inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Decelerate the vehicle speed by depres-
sing the brake pedal, depending on the
distance to the vehicle ahead and the
surrounding circumstances in order to
maintain a safe distance between vehi-
cles.
. 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

JVS0250M
.The distance to the vehicle ahead will
change according to the vehicle speed.
The higher the vehicle speed, the
longer the distance.
. If the INFINITI Direct Response Hybrid
®
System is stopped, the set distance
becomes “long”. (Each time the hybrid system is started, the initial setting
becomes
“long”.)
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 ICC system display. Decelerate by
depressing the brake pedal to maintain a
safe vehicle distance if:
.The chime sounds.
. The vehicle ahead detection and set
distance indicator blink.
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 other vehicles
that are parked or moving slowly.
. The accelerator pedal is depressed,
overriding the system.

CONVENTIONAL (fixed speed)
CRUISE CONTROL MODE
This mode allows driving at a speed
between 25 to 90 MPH (40 to 144 km/h)
without keeping your foot on the accel-
erator pedal.
WARNING
. In the conventional (fixed speed) cruise
control mode, a warning chime does not
sound to warn you if you are too close to
the vehicle ahead, as neither the pre-
sence of the vehicle ahead nor the
vehicle-to-vehicle distance is detected.
. Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur.
. Always confirm the setting in the In-
telligent Cruise Control system display.

. The system may not detect the vehicle in
front of you in certain road or weather
conditions. To avoid accidents, never use
the DCA system under the following
conditions:
—On roads with sharp curves
—On slippery road surfaces such as
on ice or snow, etc.
—During bad weather (rain, fog, snow,etc.)
—When rain, snow or dirt adhere tothe system sensor
—On steep downhill roads (frequentbraking may result in overheating
the brakes)
—On repeated uphill and downhillroads .
In some road or traffic conditions, a
vehicle or object can unexpectedly come
into the sensor detection zone and cause
automatic braking. You may need to
control the distance from other vehicles
using the accelerator pedal. Always stay
alert and avoid using the DCA system
when it is not recommended in this
section.

system forward indicator (orange) and the
“front radar obstruction”warning message
will appear in the vehicle information
display.
Action to take:
If the driver assist system forward indicator
(orange) and the warning message appear,
park the vehicle in a safe place, turn the
hybrid system off. When the radar signal is
temporarily interrupted, clean the sensor
area of the front bumper and restart the
hybrid system. If the warning message
continues to be displayed, have the DCA
system checked by an INFINITI retailer.
Condition C:
When the DCA system is not operating
properly, the chime sounds, the driver
assist system forward indicator (orange)
and the system “malfunction” warning
message will appear in the vehicle infor-
mation display. Action to take:

The forward emergency braking system can
assist the driver when there is a risk of a
forward collision with the vehicle ahead in
the traveling lane.
JVS0235X
The forward emergency braking system
uses a radar sensor
*Alocated behind
the lower grille of the front bumper to
measure the distance to the vehicle ahead
in the traveling lane.
The forward emergency braking system
operates at speeds above approximately
3 MPH (5 km/h). If there is a risk of a
collision, the forward emergency braking
system issues a visual and audible warn-
ing and pushes the accelerator pedal up. If
the driver releases the accelerator pedal,
then the forward emergency braking sys-
tem applies partial braking. If the driver
does not take action, the forward emer- gency braking system issues the second
visual and audible warning, and applies
harder braking.
WARNING
.
The forward emergency braking system
is a supplemental aid to the driver. It is
not a replacement for the driver’s atten-
tion to traffic conditions or responsibility
to drive safely. It cannot prevent acci-
dents due to carelessness or dangerous
driving techniques.
. The forward emergency braking system
does not function in all driving, traffic,
weather and road conditions.
