Setting On Roller Dynamometer

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2006 BMW X5, 2005 BMW X5, 2004 BMW X5, 2003 BMW X5, and 2002 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

WARNING: Use only brake dynamometers whose test speed is 3 mph (5 km/h) or less. Follow without fail the guidelines contained in the operating instructions of the relevant test stand manufacturer. Failure to do so may result in damage to the vehicle and the system and also personal injury.

CAUTION: The maximum test duration for four-wheel drive vehicles is 3 minutes per axle. If the test has to be repeated, the vehicle must be driven over a distance of at least .6 miles (1 km) to ensure the transfer case is sufficiently lubricated.

Check tires for damage. Check tire treads. Check tire pressures.

NOTE: On cars equipped with ASC+T or DSC, the system must be deactivated with the switch. ASC+T/DSC indicator lamp in instrument cluster must light up.

The brakes must be at normal operating temperature. To achieve this, brake the car several times to slightly warm and dry brake discs and drums.

With parking brake released, shift transmission into neutral. Wheel circumferential force at idle should be less than or equal to 150 N.
At first tooth, there is no brake force increase. Indicator lamp may be lit.
At second tooth, indicator lamp must be lit.
At third tooth, adjust parking brake cables until brake force indicator shows 500-550N.
