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. There-
fore, we have one request:
Please take the time to read this Owner's Manual and
familiarize yourself with the information that we have com-
piled for you before starting off in your new BMW. The
manual contains important data and instructions intended
to assist you in obtaining maximum satisfaction from your
BMW's unique array of advanced technical features. It also
contains information on vehicle maintenance designed to
enhance operating safety while simultaneously helping you
to maintain your BMW's value throughout an extended ser-
vice life. For additional information refer to the supplemen-
tal manuals.
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.
We wish you an enjoyable driving experience.
