Great - thanks for confirming!

This is really useful, I'm due to order a new battery from Lexuspartsdirect after getting my battery tested. Halfords said that it was ready to be changed but they wouldn't do it because when you disconnect it, it may reset a lot of the functions in a hybrid and they'd recommend taking it to a dealer. Is this true? Do I need to take any additional precautions if I change the battery myself over and above taking off the negative first and reconnecting to the new battery last? Thanks!
