Technology for comfort, convenience and safety xDrive xDrive is the 4-wheel drive system of your BMW. The combined effects of xDrive and DSC further optimize the traction and dynamic driving characteristics. The 4-wheel drive system xDrive variably distributes the drive forces to the front and rear axle depending on the driving situation and prevailing road conditions. Malfunction Malfunctions are displayed via Check Control, refer to page 77. HDC Hill Descent Control The concept HDC is a system for driving downhill in steep terrain. This system reduces vehicle speed on steep downhill gradients, thus allowing you to maintain even better control of your BMW under these conditions. The vehicle moves at approximately walking speed without active intervention from the driver. HDC is available for activation at vehicle speeds below approx. 22 mph/35 km/h. When driving down steep hills with a speed below approx. 22 mph/35 km/h, the vehicle reduces speed automatically down to approximately walking speed, approx. 5 mph/8 km/h, and then maintains this speed at a constant. Only use HDC in transmission positions D or R. Dynamic Performance Control* The concept Dynamic Performance Control optimizes the handling characteristics of your BMW when starting off, cornering, and during evasive maneuvers. To achieve this, the system variably distributes the drive torque of the rear axle to the two rear wheels. This further increases the steering precision and tracking stability of your vehicle. Display The Control Display shows how xDrive and Dynamic Performance Control are distributing the drive forces. Increasing or reducing speed You can use the accelerator or brakes to vary this automatically controlled speed within a range extending from approx. 4 mph/6 km/h to 15 mph/25 km/h. You can specify a target speed within the same range by using the lever of the cruise control. With downhill grade over 10Ξ you can reduce the speed to approx. 3 mph/4 km/h. Pull the lever of the cruise control beyond the resistance point, arrow 3. Press the BC button in the turn signal lever, refer to page 73, until the display appears. The current distribution of drive forces is indicated by arrows pointing to all four wheels. The highlighted arrows show the drive forces currently present. The longer an arrow is, the greater the drive forces in the associated wheel. The transparent arrows indicate the maximum value the drive forces over the last 10 seconds. 1 2 Increasing speed Pull to the resistance point: Reduce speed to approx. 4 mph/6 km/h 90 Online Edition for Part no. 01 41 2 602 756 - © 06/09 BMW AG
