⚠️ Lexus ES — Moderate misfuel risk
ES is petrol or hybrid petrol only in New Zealand. Diesel nozzle mis-match is rare; contaminated or wrong-grade petrol still requires tank draining before restart.
If the engine was not started
Keep ignition off; drain tank via access panel before priming.
If the engine was started
Replace fuel filter, inspect injectors and high-pressure pump (if equipped), and clear fuel-related DTCs per TIS / Techstream.
⚠️ Lexus position — ES
Lexus documents fuel pump module removal via under-rear-seat access on most ES generations. Misfuel is factory warranty-excluded misuse.
