ADDITIONAL INFORMATION

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 Lexus. To help remind customers that regular service is essential to the proper
maintenance of the vehicle, dealers are required to input their dealer information and set the
service reminder on the Navigation Screen before delivery. By doing this, customers will be
reminded to return to your dealership for service. (See Page 2 of the GX 550 PDS Check Sheet,
“Set Dealer and Service Reminder.”)
This bulletin contains the PDS procedures that apply specifically to the 2024 model year GX 550.
To properly perform a complete PDS, you must complete all procedures contained in this TSB as
well as the GX 550 PDS Check Sheet.
In addition, if the vehicle is stored for over 30 days, be sure to follow Long-Term Vehicle
Storage Guidelines.
