OPERATING YOUR VEHICLE
When there is a large temperature gap
between inside of the vehicle and outside
air (such as winter), windshield is easy to
fog. If the front portion of dual sensor on
the windshield is fogged up or covered
with condensation or ice, dual sensor
brake support system may not activate
temporarily. In this case, use the wind-
shield defroster to remove the fog, etc.
When cleaning inside of the windshield, do
not adhere the glass cleaner to lens.
