From CivicWithACord:
Maintenance:
a) During summer, tire pressure will increase. Check to make sure that they read 42 PSI.
During the winter, tire pressure will decrease. Check to make sure that they read 42 PSI.
b) Brakes likely will tend to wear faster. Listen for the audible brake wear indicators.
c) Motor brushes: Need to be changed every 80,000 miles or so. They are a black block with a copper braid coming out of them, visible in the tailshaft end of the motor. Monitor the height that the block sticks out, so you'll know when replacement is needed. There is a special stone that you purchase to shape them, when the time comes. Many companies can repair electric motors, ie, tell you how to install the brushes, and it's not difficult.
