Toyota Prius Prime 2023 Manual

Introduction

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. 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 8 of "Final Inspection and Cleaning.")
This bulletin contains the PDS procedures that apply specifically to 2023 model year Prius Prime vehicles. A universal PDS Check Sheet that contains PDS steps that apply to all 2023 model year Toyota vehicles has been developed. To properly perform a complete PDS, you must complete all procedures contained in this TSB as well as the universal PDS Check Sheet.
In addition, if the vehicle is stored for over 30 days, be sure to follow Long-Term Vehicle Storage Guidelines.

Enable Hybrid Battery Thermal Keep Control Mode

HV/BEV battery may be frozen in extremely cold areas. As a result, the HV/BEV battery may become excessively weak, and the system may NOT be able to be started. By enabling HV/BEV Battery Thermal Keep Control Mode, it is possible to warm the HV/BEV battery and maintain its current temperature in order to prevent it from becoming excessively weak.
When this mode is set to ON, the timer charging settings are canceled at temperatures of 14°F (-10°C) or lower. Charging will begin immediately when the charging cable is connected to the vehicle.
