Q: How to perform routine maintenance on a Lexus ES300's doors, hood, trunk or liftgate's locks and hinges to ensure smooth operation and prevent wear?
A: Routine maintenance involves applying a few drops of light oil or lock lubricant to the hinges and latch assemblies of doors, Hood, and trunk (or liftgate) every 3000 miles or every three months. Additionally, lubricate the door latch strikers with a thin layer of grease for reduced wear and improved movement. Use spray-on graphite lubricant to maintain door and trunk (or liftgate) locks.
