TECHNICAL SERVICE BULLETIN
SUBJECT:

PASSENGER FLOOR WET DURING A/C OPERATION .
This bulletin provides information relating to the possible presence of moisture on the
passenger side floor during NC operation on some Rio vehicles produced from October
15th, 20 11 to September 20th, 2012 (for 4DR models) and July 11th, 20 11 to September
20th, 2012 (for 5DR models). T his condition may be due to insufficiently insulated evaporator
lines allowing condensation to form on the lines which then drips onto the passenger floor.
To correct this condition , install additional insulating material over the evaporator lines as
outlined in this bulletin, making sure to completely wrap the lines from the evaporator core to
the expansion valve , in order to prevent condensation from recurring .
