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 com-
piled for you before starting off in your new vehicle. It con-
tains important data and instructions intended to assist you
in gaining maximum use and satisfaction from your BMW's
unique range of technical features. The manual also con-
tains information on maintenance designed to enhance
operating safety and contribute to maintaining 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
Information Booklet for US models or a Warranty and
Service Guide Booklet for Canadian models.
We wish you an enjoyable driving experience.
