PRECAUTIONS ON CRUISE
CONTROL
.If the cruise control system malfunctions,
it will cancel automatically. The SET
indicator on the vehicle information dis-
play will then blink to warn the driver.
. If the engine coolant temperature be-
comes excessively high, the cruise con-
trol system will be canceled
automatically.
. If the SET indicator blinks, turn the cruise
control main switch off and have the
system checked. It is recommended you
visit an INFINITI retailer for this service.
. The SET indicator may sometimes blink
when the cruise control main switch is
turned ON while pushing the COAST/
SET, ACCELERATE/RESUME or CAN-
CEL switch. To properly set the cruise
control system, perform the steps below
in the order indicated.
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.

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.JVS0082M
. 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”.)

Condition B:
The chime sounds and the ICC system
warning light (orange) will come on and the
“FRONT RADAR OBSTRUCTION” warning
will appear.
. When the radar sensor area is covered
with dirt or is obstructed, making it
impossible to detect a vehicle ahead,
the ICC system is automatically can-
celed.
Action to take:
If the warning light comes on, stop the
vehicle in a safe place, place the shift lever in
the P (Park) position and turn the engine off.
When the radar signal is temporarily inter- rupted, clean the sensor area of the front
bumper and restart the engine. If the
“FRONT RADAR OBSTRUCTION” warning
continues to be displayed, have the ICC
system checked. It is recommended you visit
an INFINITI retailer for this service.
.
When driving on roads with limited road
structures or buildings (for example, long
bridges, deserts, snow fields, driving next
to long walls), the system may illuminate
the ICC system warning light (orange)
and display the “FRONT RADAR OB-
STRUCTION” warning.
Action to take:
When the conditions listed above are no
longer present, turn the ICC system back on
to use the system.

System maintenance
The sensor for the ICC systemis located
behind the lower grille of the front bumper.
To keep the ICC system operating properly,
be sure to observe the following:
. Always keep the sensor area of the front
bumper clean.
. Do not strike or damage the areas around
the sensor.
. Do not cover or attach stickers or similar
objects on the front bumper near the
sensor area. This could cause failure or
malfunction.
. Do not attach metallic objects near the
sensor area (brush guard, etc.). This

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
DISTANCE CONTROL ASSIST
(DCA) (if so equipped)

The system will start to operate after the
vehicle speed is above approximately 3 MPH
(5 km/h).
The dynamic driver assistance switch
is
used for the Lane Departure Prevention
(LDP), Blind Spot Intervention (BSI) and
DCA systems. When the dynamic driver
assistance switch
is pushed, the LDP and
BSI systems will also turn on or off simulta-
neously. The DCA system can be individually
set to on or off on the center display and
using the center multi-function control panel
. If the system is set to off, the system will
not turn on even if the dynamic driver
assistance switch
is pushed to on. To set
the system to on or off on the display, see
“How to enable/disable the DCA system”
(P.5-94).

control mode is operating, the DCA system
will not operate. (To use the DCA system,

SYSTEM MAINTENANCE
The sensor for the DCA systemis located
behind the lower grille of the front bumper.
The DCA system is designed to automati-
cally check the sensor’s operation. 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 DCA
system may not detect them. In these
instances, the DCA system may not be able
to decelerate the vehicle properly. Be sure to
check and clean the sensor regularly.
To keep the DCA system operating properly,
be sure to observe the following:
