This phenomenon disappears after the display image has been replaced by another one.
IThe names of route and area might vary between the immediate front area and distance front area.

IdentificationNBHA0112IDENTIFICATION LABEL FOR VEHICLENBHA0112S01Vehicles with factory installed fluorescent dye have this identifica-
tion label on the under side of hood.
NOTE:
Vehicles with factory installed fluorescent dye have a green label.
Vehicles without factory installed fluorescent dye have a blue label.
Precautions for Refrigerant ConnectionNBHA0004A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
IExpansion valve to cooling unit
FEATURES OF NEW TYPE REFRIGERANT CONNECTIONNBHA0004S01IThe O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
IThe reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.
