Looking for causes of parasitic battery drain. Fuse box has symbols for each fuse, but what do they mean? Examples of those not obvious - HOLPW/W LDLEV HTDMIR.
The last one is some mirror, but which one?
Haynes manual shows a few if you search all the wiring diagrams.

Question - what do the fuse box symbols mean?

Good afternoon,

Can you send me a picture of the cover so I can tell you each one?

I attached a guide for doing a parasitic draw for the car.

The ones you ask about are -
HOLPW/W = Headlight wiper/washer
LDLEV = Electronic Load Leveling
HTDMIR. = Heated Mirror.



Two common issues for a draw are the instrument cluster and the radio.
