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 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.
This bulletin contains the PDS procedures that apply specifically to 2025 model year
GX 550 vehicles.
Refer to the universal Check Sheet that contains PDS steps that apply to all 2025 model year
Lexus vehicles. To properly perform a complete PDS, you must complete all procedures
contained in this TSB as well as the PDS Check Sheet.
In addition, if the vehicle is stored for over 30 days, refer to L-SB-0003-24, Long-Term Vehicle
Storage Guidelines.
