Misfuel risk Not applicable
The Atto 3 is battery electric with no fuel filler. Incidents involve wrong fluids in washer, brake fluid, or coolant reservoirs — not pump petrol or diesel.
If the engine was not started
Drain the affected non-fuel reservoir before operating related pumps or motors.
If the engine was started
If the washer pump ran with contaminated fluid, inspect lines and pump; replace if damaged.
Access procedure
- Identify which reservoir was filled incorrectly — there is no fuel tank on Atto 3
- If a combustible liquid was put in the washer bottle, fuel extraction and system flush the washer system
- Do not run the washer pump until the correct fluid is confirmed
- For coolant errors, follow BYD workshop manual drain and refill with specified OAT coolant
- High-voltage interlocks apply near the battery — use BYD-qualified technicians
Notes
- Type 2/CCS charging port only — not a fuel flap
