driving for smooth efficient operation.
Each time you start the vehicle, BlueDrive is activated automatically.
If needed, the driver can temporarily switch BlueDrive ON/OFF using the
steering wheel mounted button.
- BlueDrive OFF is intended for brief
periods of unusual driving, such as
steep roads or heavy loads. The cen-
ter cluster background will be Black.
- BlueDrive ON is meant for normal vehicle driving and provides maxi-

controlled driver information system that
displays information related to driving on
the LCD screen when the engine
