Important: Automatic terminal cutoff of Terminal 15 from 03/2007.
Terminal 15 is automatically switched off by the signal from the door contact when the driver's door is
opened or closed. Terminal 15 is permanently reactivated if the START/STOP button is then pressed.
Perform this operation before programming or diagnosing a vehicle.
Drive
With BMW EfficientDynamics, the Sports Activity Vehicle in the model year 2008 sets new standards in drive
dynamics and wear reduction.
The comprehensive programme for the optimisation of wear and emission performance includes intelligent alternator
control as well as requirement-based control of auxiliary units (e.g. coolant pump).
In addition the belt drive for the A/C compressor is equipped with a clutch. If the climate control system is switched
off, the A/C compressor is automatically disconnected. In this way the drag torque of the A/C compressor is reduced
to a minimum.
The scope of equipment includes roll-resistance reduced tyres, a friction-minimised rear axle transmission and a
modified drive assistance pump. The pressure- and volume-dependent adjustment of the cam ring prevents
transmission losses increasing in proportion to engine speed.
The vehicle is also equipped with active aerodynamic features. The vent flaps open and close depending on the
