JVS0210X

System set display with vehicle ahead
System set display without vehicle
ahead

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.

NOTE:

.

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 accelerates 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 accelera-
tion to the set vehicle speed or any time the
ICC system is in operation, the system
controls the distance to that vehicle.
When a vehicle is no longer detected under
approximately 15 MPH (24 km/h), the
system will be canceled.

JVS0211X

When passing another vehicle,

the set speed

indicator will flash when the vehicle speed
exceeds the set speed. The vehicle detect
indicator will turn off when the area ahead
of the vehicle is open. When the pedal is
released, the vehicle will return to the
previously set speed.
Even though your vehicle speed is set in the
ICC system, you can depress the accelerator
pedal when it is necessary to accelerate your
vehicle rapidly.

How to change the set vehicle
speed

To cancel the preset speed,

use any of these

methods:

.

Push the CANCEL switch. The set vehicle

speed indicator will go out.

.

Tap the brake pedal. The set vehicle

speed indicator will go out.

.

Turn the MAIN switch off. Both the

Intelligent Cruise Control system set
indicator (green) and set vehicle speed
indicator will go out.

To reset at a faster cruising speed,

use one

of the following methods:

.

Depress the accelerator pedal. When the

vehicle attains the desired speed, push
and release the SET/COAST (-) switch.

.

Push and hold the RESUME/ACCELER-

ATE (+) switch. The set vehicle speed will
increase by approximately 5 MPH (5
km/h for Canada).

.

Push, then quickly release the RESUME/

ACCELERATE (+) switch. Each time you
do this, the set speed will increase by
approximately 1 MPH (1 km/h for Ca-
nada).

To reset at a slower cruising speed,

use one

of the following methods:

.

Lightly tap the brake pedal. When the

vehicle attains the desired speed, push

the SET/COAST (-) switch and release it.

.

Push and hold the SET/COAST (-)

switch. The set vehicle speed will de-
crease by approximately 5 MPH (5 km/h
for Canada).

.

Push, then quickly release the SET/

COAST (-) switch. Each time you do this,
the set speed will decrease by approxi-
mately 1 MPH (1 km/h for Canada).

To resume the preset speed,

push and

release the RESUME/ACCELERATE (+)
switch. The vehicle will resume the last set
cruising speed when the vehicle speed is over
20 MPH (32 km/h).

How to change the set distance to
the vehicle ahead

The distance to the vehicle ahead can be
selected at any time depending on the traffic
conditions.
Each time the DISTANCE switch

is

pushed, the set distance will change to long,
middle, short and back to long again in that
sequence.

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 engine is stopped, the set distance

becomes “long”. (Each time the engine 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 depres-
sing the brake pedal to maintain a safe
vehicle distance if:

.

The chime sounds.

.

The vehicle ahead detection indicator and

set distance indicator blink.

The warning chime may not sound in some
cases when there is a short distance be-
tween 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 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, over-

riding the system.

NOTE:

The approach warning chime may sound
and the system display may blink when the

radar sensor detects objects on the side of
the vehicle or on the side of the road. This
may cause the ICC system to decelerate or
accelerate the vehicle. The radar sensor may
detect these objects when the vehicle is
driven on winding 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

A chime sounds under the following condi-
tions and the control is automatically can-
celed.

.

When the vehicle ahead is not detected

and your vehicle is traveling below the
speed of 15 MPH (24 km/h)

.

When the system judges the vehicle is at

standstill

.

When the shift lever is not in the D

position or Manual mode

.

When the parking brake is applied

.

When the INFINITI Drive Mode Selector

is turned to the SNOW mode

.

When the VDC system is turned off

.

When ABS or VDC (including the traction

control system) operates

.

When distance measurement becomes

impaired due to adhesion of dirt or
obstruction to the sensor

.

When a wheel slips

.

When the radar signal is temporarily

interrupted

Vehicle-to-vehicle distance control
mode limitations

WARNING

Listed below are the system limitations
for the ICC system. Failure to operate
the vehicle in accordance with these
system limitations could result in serious
injury or death.

.

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 con-
gested areas.

.

This system will not adapt automati-
cally 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

Starting and driving

5-81

5-82

Starting and driving

roads, in heavy rain or in fog.

.

As there is a performance limit to the
distance control function, never rely
solely on the ICC system. This system
does not correct careless, inattentive
or absent-minded driving, or over-
come poor visibility in rain, fog, or
other bad weather. Decelerate the
vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain 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.

.

Always pay attention to the opera-
tion of the vehicle and be ready to
manually control the proper follow-
ing distance. The vehicle-to-vehicle
distance control mode of the ICC
system may not be able to maintain
the selected distance between vehi-
cles (following distance) or selected
vehicle speed under some circum-

stances.

.

The system may not detect the
vehicle in front of you in certain road
or weather conditions. To avoid ac-
cidents, never use the ICC system
under the following conditions:

— On roads where the traffic is

heavy or there are 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 to

the system sensor

— On steep downhill roads (the

vehicle may go beyond the set
vehicle speed and frequent brak-
ing may result in overheating the
brakes)

— On repeated uphill and downhill

roads

— When traffic conditions make it

difficult to keep a proper distance
between vehicles because of fre-
quent acceleration or deceleration

.

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 accel-
erator pedal. Always stay alert and
avoid using the ICC system when it is
not recommended in this section.

The radar sensor will not detect the follow-
ing objects:

.

Stationary and slow moving vehicles

.

Pedestrians or objects in the roadway

.

Oncoming vehicles in the same lane

.

Motorcycles traveling offset in the travel

lane

The sensor generally detects the signals
returned from the vehicle ahead. Therefore,
if the sensor cannot detect the reflection
from the vehicle ahead, the ICC system may
not maintain the selected distance.
The following are some conditions in which
the sensor cannot detect the signals:

.

When the snow or road spray from

traveling vehicles reduces the sensor’s
visibility

.

When excessively heavy baggage is

loaded in the rear seat or the trunk of
your vehicle

The ICC system is designed to automatically
check the sensor’s operation within the
limitation of the system. When the sensor

is covered with dirt or is obstructed, the
system will automatically be canceled. If the
sensor is covered with ice, a transparent or
translucent vinyl bag, etc., the ICC system
may not detect them. In these instances, the
vehicle-to-vehicle distance control mode
may not cancel and may not be able to
maintain the selected following distance
from the vehicle ahead. Be sure to check
and clean the sensor regularly.

SSD0252

The detection zone of the radar sensor is
limited. A vehicle ahead must be in the
detection zone for the vehicle-to-vehicle
distance detection mode to maintain the
selected distance from the vehicle ahead.
A vehicle ahead may move outside of the
detection zone due to its position within the
same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are
traveling offset from the centerline of the
lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has
completely moved into the lane.

If this

occurs, the ICC system may warn you by
blinking the system indicator and sounding
the chime. The driver may have to manually

control the proper distance away from
vehicle traveling ahead.

Starting and driving

5-83

5-84

Starting and driving

SSD0253

When driving on some roads, such as wind-
ing, hilly, curved, narrow roads, or roads
which are under construction, the radar
sensor may detect vehicles in a different
lane, or may temporarily not detect a vehicle
traveling ahead. This may cause the ICC
system to decelerate or accelerate the
vehicle.
The detection of vehicles may also be
affected by vehicle operation (steering man-
euver or traveling position in the lane, etc.) or
vehicle condition.

If this occurs, the ICC

system may warn you by blinking the
system indicator and sounding the chime
unexpectedly. You will have to manually
control the proper distance away from the

vehicle traveling ahead.

WARNING

Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.

.

Always drive carefully and atten-
tively when using the DCA system.
Read and understand the Owner’s
Manual thoroughly before using the
DCA system. To avoid serious injury
or death, do not rely on the system to
prevent accidents or to control the
vehicle’s speed in emergency situa-
tions. Do not use the DCA system
except in appropriate road and traffic
conditions.

.

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.

.

As there is a performance limit to the
distance control function, never rely
solely on the DCA system. This sys-
tem does not correct careless, inat-
tentive or absent-minded driving, or
overcome poor visibility in rain, fog,
or other bad weather. Decelerate the

vehicle speed by depressing the brake
pedal, depending on the distance to
the vehicle ahead and the surround-
ing circumstances in order to main-
tain a safe distance between vehicles.

.

Always pay attention to the opera-
tion of the vehicle and be ready to
manually decelerate to maintain the
proper following distance. The DCA
system may not be able to decelerate
the vehicle under some circum-
stances.

.

This system only brakes and moves
the accelerator pedal upward to help
assist the driver to maintain a follow-
ing distance from the vehicle ahead.
Acceleration should be operated by
the driver.

.

The DCA system does not control
vehicle speed or warn you when you
approach stationary and slow moving
vehicles. You must pay attention to
vehicle operation to maintain proper
distance from vehicles ahead.

.

The DCA system automatically de-
celerates your vehicle to help assist
the driver to maintain a following
distance from the vehicle ahead.
Manually brake when deceleration is
required to maintain a safe distance
upon sudden braking by the vehicle

ahead or when a vehicle suddenly
appears in front of you. Always stay
alert when using the DCA system.

.

If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill
within the limitations of the system.
The system will cancel with a warning
chime once it judges that the vehicle
has come to a standstill. To prevent
the vehicle from moving, the driver
must depress the brake pedal.

JVS1123X

The DCA system is intended to assist the
driver in keeping a following distance from
the vehicle ahead traveling in the same lane
and direction.
If the radar sensor

detects a slower

moving vehicle ahead, the system will reduce
the vehicle speed to help assist the driver to
maintain a following distance.
The system automatically controls the throt-
tle and applies the brakes (up to approxi-
mately 40% of vehicle braking power) if
necessary.
The detection range of the sensor is approxi-
mately 650 ft (200 m) ahead.

DCA SYSTEM OPERATION

WARNING

Failure to follow the warnings and
instructions for proper use of the DCA
system could result in serious personal
injury or death.

.

When the vehicle ahead detection
indicator is not illuminated, system
will not control the vehicle 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
accelerator pedal, the system may
not be able to assist the driver to
release the accelerator pedal appro-
priately.

The DCA system brakes and moves the
accelerator pedal upward according to the
distance from and the relative speed of the
vehicle ahead to help assist the driver in
maintaining a following distance. The sys-
tem will decelerate as necessary and if the
vehicle ahead comes to a stop, the vehicle
decelerates to a standstill. However, the
DCA system can only apply up to approxi-

mately 40% of the vehicle’s total braking
power. If a vehicle moves into the traveling
lane ahead or if a vehicle traveling ahead
rapidly decelerates, the distance between
vehicles may become closer because the
DCA system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA
system will sound a warning chime and blink
the system display to notify the driver to
take necessary action.
See “Approach warning” (P.5-95).
