SEAL wiper service position and blade care
For the original SEAL handbook EN-250305, use infotainment settings → DiLink → Overhaul → Front wiper check before lifting the front arms. For automatic rain sensing, check both the stalk’s Auto position and Vehicle → Comfort Driving → Auto Wiper.
- Park, select P, keep the bonnet closed and switch automatic wiping off.
- Let frozen blades thaw and remove ice with a suitable scraper.
- For blade maintenance, open infotainment settings → DiLink → Overhaul and enable Front wiper check.
- Wait until the arms stop, then lift carefully while supporting them. Safety note: Support raised arms and keep the bonnet closed to prevent glass or body damage. Keep hands clear during motion, and use the manual wiping needed for a clear view rather than testing Auto with inadequate visibility; avoid running the blades on frozen or dry glass.
- Check replacement blades lock correctly, then lower the arms slowly.
- Disable maintenance mode and check normal parking and wiping while stationary on wet glass.
Adjusting automatic wiping
This is separate from maintenance mode. In the March 2025 handbook, select Auto/intermittent on the stalk and enable Vehicle → Comfort Driving → Auto Wiper. The rain sensor is by the interior rear-view mirror. The stalk knob has four sensitivity levels: upward reduces sensitivity; downward increases it. Compare one level at a time in normal rain while parked. Switch Auto off before cleaning the glass or entering a car wash.
Use the matching edition
PDF 183–184 (printed 182–183) covers front-wiper care; PDF 68 (printed 67) covers the switch and rain sensor. A 2026 facelift needs its own handbook rather than an assumed copy of these labels.
If that did not work
If manual slow/fast wiping works but Auto does not after both settings are checked, ask BYD to check rain-sensor input, windscreen mounting/optical contact and software configuration, mentioning any windscreen replacement. Abnormal sweep, looseness, body contact or a failure to park also needs inspection.
What to note down for support: For an Auto-only fault, the screen setting, stalk position, sensitivity and rain conditions help. If all wiping fails after thawing and clearing obstruction, report that distinction.
