PRECAUTIONS ON CRUISE CONTROL
●If the cruise control system malfunctions, it
will cancel automatically. The SET indicator
on the dot matrix crystal display will then
blink to warn the driver.
● If the engine coolant temperature becomes
excessively high, the cruise control system
will be canceled automatically.
● If the SET indicator blinks, turn the cruise
control main switch off and have the system
checked by your INFINITI retailer.
● The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the
RESUME/ACCELERATE, SET/COAST or CAN-
CEL switch. To properly set the cruise control
system, perform the steps below in the order
indicated.
WARNING

CRUISE CONTROL
Starting and driving5-19

The Intelligent Cruise Control (ICC) system au-
tomatically maintains a selected distance from
the vehicle traveling 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.
The ICC function can be set to one of two cruise
control modes:
●Vehicle-to-vehicle distance control mode:
For maintaining a selected distance between
your vehicle and the vehicle in front of you
up to the preset speed.
● Conventional (fixed speed) cruise control
mode:
For cruising at a preset speed.WARNING
●Always drive carefully and attentively when
using either cruise control mode. Read and
understand the Owner’s Manual thoroughly
before using the cruise control. To avoid se-
rious injury or death, do not rely on the sys-
tem to prevent accidents or to control the
vehicle’s speed in emergency situations. Do
not use cruise control except in appropriate
road and traffic conditions.
● In the conventional (fixed speed) cruise con-
trol 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.

PRECAUTIONS ON VEHICLE-TO-
VEHICLE DISTANCE CONTROL MODE
The system is intended to enhance the opera-
tion 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 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 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 sys-
tem 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

This system will not automatically brake the ve-
hicle to a stop.
WARNING
●As there is a performance limit to the dis-
tance control function, never rely solely on
the Intelligent Cruise Control system. This
system does not correct careless, inatten-
tive or absent-minded driving, or overcome
poor visibility in rain, fog, or other bad
weather. Decelerate the vehicle speed by de-
pressing the brake pedal, depending on the
distance to the vehicle ahead and the sur-
rounding circumstances in order to maintain
a safe distance between vehicles.
● Although the brake operation is controlled
by the system, the system does not auto-
matically stop the vehicle. If the vehicle
speed falls below approximately 20 MPH (32
km/h), the Intelligent Cruise Control system
is automatically 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 condi-
tions. To avoid accidents, never use the In-
telligent Cruise Control 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 the windshield wiper is operated at
the low speed (LO) or high speed (HI) po-
sition, the Intelligent Cruise Control sys-
tem is automatically canceled.
– When strong light (for example, at sun- rise or sunset) is directly shining on the
front of the vehicle
– When rain, snow or dirt adhere to the sys- tem sensor
– On steep downhill roads (the vehicle may go beyond the set vehicle speed and fre-
quent braking 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 frequent 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 dis-
tance from other vehicles using the accelera-
tor pedal. Always stay alert and avoid using
the ICC system when it is not recommended
in this section.

instances, the vehicle-to-vehicle distance con-
trol 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.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the slower vehicle
ahead; the system will decelerate the vehicle as
necessary. However, the ICC system can only
apply up to 25% of the vehicles total braking
power. This system should only be used when
traffic conditions allow vehicle speeds to re-
main fairly constant or when vehicle speeds
change gradually. If a vehicle moves into the
traveling lane ahead or if a vehicle traveling
ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
ICC system cannot decelerate the vehicle
quickly enough. If this occurs, 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 (32 km/h). The system will also disengage
below the 20 MPH (32 km/h) cut-off speed or
over the maximum set speed.
See “Approach warning” later in this section.The following items are controlled in the
vehicle-to-vehicle distance control mode:
●
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 approximately
25 and 90 MPH (40 and 144 km/h).
● When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode ad-
justs the speed to maintain the distance,
selected by driver, from the vehicle ahead.
The adjusting speed range is between ap-
proximately 20 MPH (32 km/h) and up to 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 vehicle 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.

To set cruising speed,accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (Vehicle ahead detection indica-
tor, set distance indicator and set vehicle speed
indicator come on.) Take your foot off the
accelerator pedal. Your vehicle will maintain the
set speed. When the SET/COAST switch is pushed under
the following conditions, the system cannot be
set and the ICC indicators will blink for approxi-
mately 2 seconds:
●
When traveling below 25 MPH (40 km/h) and
the vehicle ahead is not detected
● When the selector lever is not in the D, DS or
Manual mode
● When the windshield wipers are operating at
low (LO) or high speed (HI).
● When the brakes are operated by the driver When the SET/COAST switch is pushed under
the following conditions, the system cannot be
set.
A warning chime will sound and the ICC indica-
tors will blink.
●
When the SNOW mode switch is ON (To use
the ICC system, turn off the SNOW mode
switch, push the MAIN switch to turn off the
ICC and reset the ICC switch by pressing the
MAIN switch again.)
For details about the SNOW mode switch,
see “SNOW MODE SWITCH” in the “2. Instru-
ments and controls” section.

WARNING
Normally when controlling the distance to a
vehicle ahead, this system automatically accel-
erates or decelerates your vehicle according to
the speed of the vehicle ahead. Depress the
accelerator to properly accelerate your vehicle
when acceleration is required for a lane
change. Depress the brake pedal when decel-
eration 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 main-
tains 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 con-
trolling 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 brak-
ing 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.

Each time the DISTANCE switchAis pushed,
the set distance will change to long, middle,
short and back to long again in that sequence. ●
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 dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
●The chime sounds.
● The vehicle ahead detection and set dis-
tance 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 vehicles is in-
creasing
● When a vehicle cuts in near your vehicle
SSD0613D
5-36Starting and driving

The warning chime will not sound when:
●Your vehicle approaches other vehicles that
are parked or moving slowly.
● The accelerator pedal is depressed, overrid-
ing the system.
NOTE:
The approach warning chime may sound and the
system display may blink when the ICC sensor
detects some reflectors
Awhich are fitted on
vehicles in other lanes or on the side of the road.
This may cause the ICC system to decelerate or
accelerate the vehicle. The ICC sensor may de-
tect these reflectors when the vehicle is driven
on winding roads, hilly roads or when entering
or exiting a curve. The ICC sensor may also de-
tect reflectors on narrow roads or in road con-
struction zones. 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 condi-
tion (for example, if a vehicle is being driven
with some damage).
Automatic cancellation
A chime sounds under the following conditions
and the control is automatically canceled.
●
When the vehicle speed falls below approxi-
mately 20 MPH (32 km/h)
● When the selector lever is not in the D
(Drive), DS (Drive Sport) or manual shift
mode
● When the windshield wipers are operated at
low speed (LO) or high speed (HI)
● When the SNOW mode switch is turned on
● When the VDC is turned off
● When the VDC operates
