Testing On Brake Dynamometer

CAUTION: You should only use brake dynamometers whose test speed is no greater than 2 mph (5 km/h). You must follow 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.

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