2005 BMW 645CI CONVERTIBLE technical data

645CiOwner's Manual for Vehicle
Congratulations, and thank you for choosing a BMW.
Thorough familiarity with your vehicle will provide you with
enhanced control and security when you drive it. We therefore
have this request:
Please take the time to read this Owner's Manual and familiarize
yourself with the information that we have compiled for you
before starting off in your new vehicle. It contains important data
and instructions intended to assist you in gaining maximum use
and satisfaction from your BMW's unique range of technical fea-
tures. The manual also contains information on maintenance
designed to enhance operating safety and contribute to main-
taining the value of your BMW throughout an extended service
life.
This Owner's Manual should be considered a permanent part of
this vehicle. It should stay with the vehicle when sold to provide
the next owner with important operating, safety and maintenance
information.
This manual is supplemented by a Service and Warranty Informa-
tion Booklet for US models or a Warranty and Service Guide
Booklet for Canadian models.
We wish you an enjoyable driving experience.
