• NEVER let the 12-volt battery go dead - it will cause the hybrid battery to go dead too.
• Avoid driving in a manner that causes frequent recals. Prolonged acceleration, aggressive stop-and-go, extended hill climbing can cause this.
• Park the car in a garage when possible to avoid extreme temperatures
• If your car is in a collision, check to make sure everything electrical and hybrid is working properly (autostop wiring was not done in my case).

Stuff I'm not sure of....

• Forced autostops - does more power surges risk damage to the MCM and BCM black boxes protecting the battery, etc? Don't know. Hypermiling is not worth damaging the hybrid battery.
• The MIMA upgrade - As much as I'd like to get a 20-30% boost in fuel economy, I'm not as willing to consider this.
