⚠️ Toyota Vanguard — Moderate misfuel risk
Vanguard imports are petrol only. Diesel in petrol tank is the typical NZ forecourt error; contaminated petrol still requires full tank drain before restart.
If the engine was not started
Do not crank the engine. Drain tank via OEM access before any start attempt.
If the engine was started
Replace fuel filter; inspect injectors and catalytic converter if engine ran on diesel-contaminated petrol; follow TIS diagnostics.
⚠️ Toyota position — Vanguard
Toyota service information for ACA33/GSA33 Vanguard documents fuel module removal via rear-seat access panel on most examples. Misfuel is excluded from warranty. Use Toyota Global TIS procedures shared with contemporary RAV4 where platform aligns.

Frequently asked questions
Was the Toyota Vanguard sold new in New Zealand?
No. NZ examples are overwhelmingly used Japanese imports. Remediation still follows Toyota TIS for the ACA33/38 or GSA33 chassis code.
What if I put diesel in my Vanguard?
Do not start the engine. Vanguard is petrol only. Drain via Toyota fuel pump access and replace the filter before refilling with petrol.
Can I siphon petrol from the Vanguard filler neck?
NZIFDA certified repair facilities use Toyota OEM-prescribed module or tank access only. Filler-neck siphoning is not a certified misfuel recovery process in New Zealand.
