If the ICC system malfunctions, it will be
turned off automatically, a chime will
sound, and the speed control status
warning (orange) will illuminate.

If the warning light comes on, stop the ve-
hicle in a safe place. Turn the engine off,

system or the indicator stays on, it may be
a malfunction. Although the normal driving
can be continued, the ICC system shouldbe inspected. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the ICC system is temporarily unavail-
able, the conventional cruise control
mode may still be used. For additional
information, please see “Conventional
(fixed speed) cruise control mode”
(P. 5-123).
ICC sensor maintenance
The radar sensor is located on the front of
the vehicle.
To keep the ICC system operating properly,
be sure to observe the following:
• Always keep the sensor area of the front
bumper/emblem clean.
• Do not strike or damage the areas around the sensor.
• Do not attach a sticker (including trans- parent material) or install an accessory
near the sensor. This could cause failure
or malfunction.
• Do not attach metallic objects near the sensor area (brush guard, etc.). This could
cause failure or malfunction.
• Do not alter, remove, or paint the front bumper. Before customizing or restoring the front
bumper, it is recommended that you visit a
NISSAN dealer.
The camera sensor is located above the
inside mirror.
To keep the proper operation of the sys-
tems and prevent a system malfunction,
be sure to observe the following:
• Always keep the windshield clean.
• Do not attach a sticker (including trans-
parent material) or install an accessory
near the camera unit.
• Do not place reflective materials, such as white paper or a mirror, on the instru-
ment panel. The reflection of sunlight
may adversely affect the camera unit’s
capability of detecting the lane markers.
• Do not strike or damage the areas around the camera unit. Do not touch the
camera lens or remove the screw located
on the camera unit.
If the camera unit is damaged due to an
accident, it is recommended that you visit a

•Do not attempt to test an AWD
equipped vehicle on a 2-wheel dyna-
mometer (such as the dynamom-
eters used by some states for emis-
sions testing) or similar equipment
even if the other two wheels are
raised off the ground. Make sure that
you inform the test facility personnel
that your vehicle is equipped with
AWD before it is placed on a dyna-
mometer. Using the wrong test
equipment may result in drivetrain
damage or unexpected vehicle
movement which could result in seri-
ous personal injury or vehicle
damage.
CAUTION
• Do not operate the engine on a free
roller when any of the wheels are
raised.
• If you use the free roller, rotate four
wheels with the same speed without
raising any wheels. •
If an AWD warning message is dis-
played while driving there may be a
malfunction in the AWD system. Re-
duce the vehicle speed immediately
and have your vehicle checked. It is
recommended that you visit a
NISSAN dealer as soon as possible.
• The powertrain may be damaged if
you continue driving when the AWD
temperature or tire size incorrect
messages are displayed
• If the AWD high temperature mes-
sage is displayed while you are driv-
ing, pull off the road in a safe area,
and idle the engine. The driving
mode will change to 2WD to prevent
the AWD system from malfunction-
ing. If the warning message turns off,
you can drive again.
• If the tire size incorrect message is
displayed while you are driving, pull
off the road in a safe area with the
engine idling. Check that all tire sizes
are the same, that the tire pressure is
correct and that the tires are not ex-
cessively worn. •
If a warning message continues to be
displayed af ter the above opera-
tions, have your vehicle checked as
soon as possible. It is recommended
that you visit a NISSAN dealer for this
service.
