# Service bulletin T\-SB\-0155\-19

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

TSB: Pre\-Delivery Service \(PDS\) is a critical step in satisfying our new car customers. Customer feedback indicates the following areas deserve special attention when performing PDS: ? Careful inspection for paint chips/scratches and body dents/dings. ? Proper operation of electrical accessories \(including interior light, clock, and radio reset\). ? Interior cleanliness. ? Proper function of mechanical systems. Customer retention and proper maintenance of vehicles are and have always been a major focus for Toyota. To help remind customers that service is essential to the proper maintenance of the vehicle, dealers are required to install a service reminder sticker prior to delivery. By doing this, customers will be reminded to return to your dealership for service. Your current service reminder sticker may be used. \(See PDS Check Sheet item 10 of ?Final Inspection and Cleaning.?\) A new PDS Check Sheet has been developed for the 2020 model year Mirai. Some check points have been added, expanded, or clarified. Bulletins are available for items in bold type.
