T-SB-0113-182018-10-15. Service bulletin. ELECTRICAL SYSTEM; STRUCTURE. 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 regular service is essential to the proper maintenance of the vehicle, dealers are required to install a service reminder sticker before delivery to the customer. By doing this, customers will be reminded to return to your dealership for their service. Your current service reminder sticker may be used. (See PDS Check Sheet item 8 of ?Final Inspection and Cleaning.?) A new PDS Check Sheet has been developed for the 2019 model year Highlander and Highlander HV. Some check points have been added, expanded, or clarified. Bulletins are available for items in bold.
