●If the SET indicator light blinks, turn the
cruise control switch off and have the sys-
tem checked by an INFINITI dealer.
● The SET indicator light may blink when the
cruise control main switch is turned ON
while pushing the ACCEL/RES,
COAST/SET, or CANCEL switch (located
on the steering wheel) . To properly set the
cruise control system, use the following pro-
cedures.
WARNING
Do not use the cruise control when driving
under the following conditions:
● When it is not possible to keep the
vehicle at a set speed.
● In heavy traffic or in traffic that varies in
speed.
● On winding or hilly roads.
● On slippery roads (rain, snow, ice, etc.) .
● In very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed be-
tween 25 - 89 MPH (40 - 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control, push the
ON·OFF switch on. The CRUISE indicator light in
the vehicle information display will illuminate.
To set cruising speed, accelerate the vehicle to
the desired speed, push the COAST/SET switch
and release it. The SET indicator light in the
vehicle information display will illuminate. Take
your foot off the accelerator pedal. Your vehicle
maintains the set speed.
● To pass another vehicle, depress the ac-
celerator pedal. When you release the
pedal, the vehicle returns to the previously
set speed.
● The vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, drive without the cruise control.
To cancel the preset speed, use one of the
following three methods.
● Push the CANCEL button; the SET indicator
light in the vehicle information display goes
out.
● Tap the brake pedal; the SET indicator light
goes out. ●
Push the ON·OFF switch off. Both the
CRUISE indicator light and SET indicator
light in the vehicle information display go out.
The cruise control is automatically canceled and
the SET light in the vehicle information display
goes out if: ● you depress the brake pedal while pushing
the ACCEL/RES or SET/COAST switch.
The preset speed is deleted from memory.
● the vehicle slows down more than 8 MPH
(13 km/h) below the set speed.
● you move the shift selector to N (Neutral) .
To reset at a faster cruising speed, use one
of the following three methods.
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch.
When the vehicle attains the speed you de-
sire, release the switch.
● Push and release the ACCEL/RES switch.
Each time you do this, the set speed in-
creases by about 1 MPH (1.6 km/h) .

To reset at a slower cruising speed,use one
of the following three methods.
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. Re-
lease the switch when the vehicle slows to
the desired speed.
● Push and release the COAST/SET switch.
Each time you do this, the set speed de-
creases by about 1 MPH (1.6 km/h) .
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) . The Intelligent Cruise Control (ICC) system au-
tomatically maintains a selected distance from
the vehicle in front of you according to that vehi-
cle’s speed, or at the set speed, if the road ahead
is clear.
The ICC function has two cruise control modes:
● Vehicle-to-vehicle distance control mode for
maintaining a selected distance between a
vehicle up to the preset speeds.
● Conventional (fixed speed) cruise control
mode for cruising at preset speeds.
WARNING
Always drive carefully and attentively
when using either cruise control mode.
Read and understand the Owner’s Manual
thoroughly before using the cruise con-
trol. To avoid serious injury or death, do
not rely on the system to prevent acci-
dents or to control the vehicle’s speed in
emergency situations. Do not use cruise
control except in appropriate road and
traffic conditions.Vehicle-to-vehicle distance control mode

SELECTING THE INTELLIGENT
CRUISE CONTROL MODE
When you push the ON/OFF switch1, you can
choose the cruise control mode between the
vehicle-to-vehicle distance control mode and the
conventional (fixed speed) cruise control mode.
To choose the vehicle-to-vehicle distance control
mode, push the ON/OFF switch quickly. The
CRUISE indicator light will appear in the vehicle
information display.
Once a control mode is chosen and activates, it
cannot be changed to the other cruise control mode. To change the mode, push the ON/OFF
switch once, then turn on the system again.
Always confirm the setting in the vehicle informa-
tion display.
WARNING
●
In the conventional (fixed speed) cruise
control mode, a warning chime will not
sound to warn you if you are too close
to the vehicle ahead.
● Pay special attention to the distance
between your vehicle and the vehicle
ahead of you or a collision could occur.
For the vehicle-to-vehicle distance control mode,
see the following description. For the conven-
tional (fixed speed) cruise control mode, see
“Conventional (fixed speed) cruise control mode”
later in this section.
VEHICLE-TO-VEHICLE DISTANCE
CONTROL MODE
In the vehicle-to-vehicle distance control mode,
the Intelligent Cruise Control (ICC) system auto-
matically maintains a selected distance from the
vehicle in front of you according to that vehicle’s
speed, up to the set speed or at the set speed
when the road ahead is clear. With ICC, the driver can maintain the same
speed as other vehicles without the constant
need to adjust the speed as you would with a
normal cruise control system.

The system is intended to enhance the operation
of the vehicle when following another vehicle
traveling in the same lane and direction.
If the distance sensor
1detects a slower mov-
ing vehicle ahead of you, the system will reduce
your speed so that you follow the vehicle in front
of you at the selected distance.
The system automatically controls the throttle
and applies the brakes (up to 25% of vehicle
braking power) if necessary.
The detection range of the sensor is approxi-
mately 390 ft (120 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 re-
sponsibility 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 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 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 or scooters traveling offset in
the travel lane This system will not automatically brake
the vehicle to a stop.
WARNING
●
As there is a performance limit to the
distance control function, never rely
solely on the Intelligent Cruise Control
system. This system does not correct
careless, inattentive or absent-minded
driving, or overcome poor visibility in
rain, fog, or other bad weather. Deceler-
ate the vehicle speed by depressing the
brake pedal, depending on the distance
to the vehicle ahead and the surround-
ing circumstances in order to maintain
a safe distance between vehicles.
● Although the brake operation is con-
trolled by the system, the system does
not automatically stop the vehicle. If the
vehicle speed falls below approxi-
mately 20 MPH (32 km/h) , the Intelli-
gent Cruise Control system is automati-
cally canceled and a warning chime
sounds. (The brake control is also
canceled.)

●The system may not detect the vehicle
in front of you in certain road or weather
conditions. To avoid accidents, never
use the Intelligent Cruise Control sys-
tem 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 the windshield wiper is
operated at the low speed (LO) or
high speed (HI) position, the Intelli-
gent Cruise Control system is auto-
matically canceled.)
– When strong light (for example, at sunrise or sunset) is directly shining
on the front of the vehicle.
– 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 barking may result in
overheating the brakes) .
– On repeated uphill and downhill roads. – When traffic conditions make it diffi-
cult to keep a proper distance be-
tween vehicles because of frequent
acceleration or deceleration.
● Do not use the Intelligent Cruise Con-
trol system if you are towing a trailer.
The system may not detect a vehicle
ahead.
● 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. Al-
ways stay alert and avoid using the ICC
system when it is not recommended in
this section.
Vehicle-to-vehicle distance mode
operation
Always pay attention to the operation of the ve-
hicle and be ready to manually control the proper
following distance. The Intelligent Cruise Control
(ICC) system may not be able to maintain the
selected distance between vehicles (following
distance) or selected vehicle speed under some
circumstances.
The vehicle-to-vehicle distance control mode
uses a sensor
1located on the front of the
vehicle to detect vehicles ahead. The sensor
generally detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if the

sensor cannot detect the reflector of 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 reflector is positioned high on the
vehicle (trailer, etc.) .
● When the reflector on the vehicle ahead is
missing, damaged or covered.
● When the reflector is covered with dirt, snow
and road spray.
● When the snow or road spray from other
vehicles reduces the sensor’s visibility.
● When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility.
● When excessively heavy baggage is loaded
in the rear seat or the cargo area of your
vehicle.
● When your vehicle is towing a trailer, etc.
The ICC system is designed to automatically
check the sensor’s operation. When the sensor is
covered with dirt or obstructions, the system will
automatically be canceled while allowing con-
ventional cruise control to remain operational. 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 clean the sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the speed of a slower
vehicle ahead; the system decelerates the ve-
hicle as necessary. However, the ICC system can
only apply up to 25% of the vehicle’s total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to remain
fairly constant or vehicle speeds change gradu-
ally. If a vehicle moves into the traveling lane
ahead or if a vehicle traveling ahead rapidly de-
celerates, the distance between vehicles may
become closer because the ICC system cannot
decelerate the vehicle quickly enough. If this oc-
curs, the ICC system will sound a warning chime
and blink the system display to notify the driver to
take necessary action.
The system will cancel and a warning chime will
sound if the speed falls below approximately 20
MPH (32km/h) . The system will also disengage
below the 20 MPH (32km/h) cut-off speed or
over the maximum set speed.
Refer to “Approach warning” later in this section.The following items are controlled when the se-
lector lever is in any D (Drive) position.
● When there are no vehicles traveling ahead,
the vehicle-to-vehicle distance control
mode maintains the speed set by the driver.
The set speed range is between approxi-
mately 25 and 89 MPH (40 and 144 km/h) .
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode
adjusts the speed to maintain the distance
selected by the driver from the vehicle
ahead. The adjusting speed range is be-
tween approximately 20 MPH (32 km/h) and
the set speed.
● When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains speed up to the set speed.
The ICC 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 when approaching toll gates
or traffic congestion.

The detection zone of the ICC 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 detec-
tion 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 enter-
ing the lane ahead may not be detected until the
vehicle has completely moved in 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 ve-
hicle traveling ahead.

When driving on some roads, such as winding,
hilly, curved, narrow, or roads which are under
construction, the ICC 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 can be affected by
vehicle operation (steering maneuver or driving
position in the lane) 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. When driving on the freeway at a set speed and
approaching a slower traveling vehicle ahead, the
ICC will adjust the speed to maintain the dis-
tance, selected by the driver, from the vehicle
ahead. If the vehicle ahead changes lanes or exits
the freeway, the ICC system will accelerate and
maintain the speed up to the set speed. Pay
attention to the driving operation to maintain con-
trol of the vehicle as it accelerates to the set
speed.
The vehicle may not maintain the set speed on
winding or hilly roads. If this happens, drive with-
out the ICC system.
