These odors may then be emitted from the vents. Odors coming from the outside air and interior can accumulate on the evaporator. As the evaporator core changes temperature, some of these odors may be released resulting in an unpleasant smell from the HVAC vents. Interior odors from sources such as air fresheners, animals, dirt, or trash can also accumulate within the HVAC system and contribute to unpleasant odors. It is normal to experience some odor upon the initial startup due to the moist/humid air that is trapped in the HVAC system, AFTER the vehicle has been parked. NOTE The procedure in this bulletin will NOT eliminate the odors described but is provided to help reduce intensity of the odors. © 2020 Toyota Motor Sales, USA T-SB-0022-20 March 10, 2020 Page 3 of 5 HVAC Odor Maintenance General Procedure (continued) 1. Confirm the condition exists. Does the vehicle exhibit odors that naturally occur from the HVAC system and/or related environmental factors? Figure 1. 1 2 YES — Continue to step 2.

Advise the customer to set the HVAC system to the outside (fresh) air mode when parking the vehicle to assist in the reduction of odors that could be trapped in the HVAC system. 3. Replace the HVAC filter on an annual basis or every 10,000 miles with a charcoal-impregnated filter (refer to the Parts Information section for the correct part). 4. If the odor condition persists, conduct an A/C evaporator cleaning service using a Toyota genuine A/C refresher kit (or equivalent) on an annual or bi-annual basis, depending on the climate conditions and customer preference. NOTE If the A/C evaporator cleaning service is NOT performed BEFORE installation of the highperformance filter, the filter may take several days to produce noticeable A/C odor improvement. © 2020 Toyota Motor Sales, USA T-SB-0022-20 March 10, 2020 HVAC Odor Maintenance A/C Evaporator Cleaning Procedure With Toyota Genuine A/C Refresher Kit 1.
