SYSTEM TEMPORARILY
UNAVAILABLE
When any of the following messages appear
on the vehicle information display, a chime
will sound and the BSI system will be turned
off automatically.
∙ “Not Available Poor Road Conditions”: When the VDC system (except traction
control system function) or ABS oper-
ates.
∙ “Currently Not Available”: When the VDC system is turned off.
∙ “Not Available: High Camera Temp”: When the camera detects that the inte-
rior temperature is high (over approxi-
mately 104°F [40°C]).
∙ “Unavailable: Side Radar Obstruction”: When side radar blockage is detected. Turn off the BSI system and turn it on again
when the above conditions no longer exist.
SYSTEM MALFUNCTION
When the BSI system malfunctions, it will be
turned off automatically, a chime will sound
and the warning message will appear in the
vehicle information display.
Action to take:
Stop the vehicle in a safe location, place the
vehicle in the P (Park) position, turn the en-
gine off and restart the engine. If the warning
light (orange) continues to illuminate, have
the system checked. It is recommended that
you visit an INFINITI retailer for this service.
SYSTEM MAINTENANCE
The lane camera unit1for the BSI system is
located above the inside mirror. The two ra-
dar sensors
2for the BSI system are located
near the rear bumper. To keep the proper
operation of the BSI system and prevent a
system malfunction, be sure to observe the
following:
∙ Always keep the windshield and the area near the radar sensors clean.

Blocked” warning message continues to be
displayed, have the system checked. It is rec-
ommended that 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 (yellow) and display the “Un-
available: Front Radar Blocked” message.
Action to take
When the conditions listed above are no lon-
ger present, turn the ICC system back on to
