note | The radar may not function normally if foreign object or dirt (snow or ice) is adhered
on the radar or its surrounding area, or the road condition is bad due to a severe weather (heavy
rain or snow). In that case, the system will deactivate the FCM as system protection and display
an alert message ("FCM RADAR BLOCKED") on the combination meter. |
