uuWhen Driving uForward Collision Warning (FCW)

Driving
■Automatic shutoff
FCW may automatically shut itself off and the FCW indicator comes and stays on
when:
• The temperature inside the system is high.
• The windshield is blocked by di rt, mud, leaves, wet snow, etc.
Once the conditions that caused FCW to shut off improve or are addressed (e.g.,
cleaning), the system comes back on.
1 Automatic shutoff
To help reduce the likelihood that high interior
temperatures will cause the ca mera system to shut off,
when parking, find a shady area or face the front of the
vehicle away from the sun.
If you use a reflective sun shade, do not allow it to
cover the camera housing. Covering the camera can
concentrate heat on the camera.
If the Can Not Operate: Camera Too Hot message
appears:
•Use the climate control system to cool down the
interior and, if necessary , the defroster mode when
windows are fogged.
•Start driving the vehicle to lower the windshield
temperature, which cool s down the area around
the FCW camera.
The camera is located
behind the rearview mirror.
Beep
The beeper sounds and the BRAKE
message appears in the multi-
information display until a possible
collision is avoided.
