Hi I have a Yaris I, BJ 2001 with webasto heater. He stood now over the holidays. This afternoon he never went on. It was NOThin’ anymore – no central locking, no light, the display either. This morning everything was still ok. Got start help, he jumped on and everything went on again. Also now light and display goes on again. I think he would also jump on, but just don’t dare me to try that too (not that then again nothing works, who i need it again on Monday.) Currently there is a 48Ah 12V Toyota battery in it. I could have a (not Toyota) with 44Ah installed today or rather tomorrow, but am still a bit skeptical, just because of the heater and would rather have one with 48Ah. Or is that “egal”, as the nice starter man said, who would also install it to me (workshop)? Which battery is by default in the Yaris? In the manual I find nothing, probably I am too blind glg Oh so, the St. andheizung I only use -4/5 degrees and always only 5-10 minutes, that is enough in the Yaris.
