Further to 4: Electronic fine balancing

For electronic fine balancing of the wheels on the vehicle, refer to operating instructions from the equipment manufacturer for information about handling the equipment.

When performing fine balancing on all wheels, start with the front axle (4a).

Due to the all-wheel drive, all four wheels must be raised and must be able to turn freely.

• Fine balancing of the front wheels to correct torsional vibrations of the steering wheel at approx. 120 km/h.
• Fine balancing of the rear wheels to correct vibration at 180 km/h and speeds greater than 230 km/h.

The following applies to both the front axle and rear axle:

• the measured-value pickups must always stand on a firm surface,
• the measuring stand support must be located as close to the wheel as possible,
• doors and lids must be closed and the vehicle must not be touched during the measuring operation,
• ensure that the lifting equipment used (jack, platform lift) does not touch the vehicle.

Affix balancing weights on the outer plane (uniform procedure / could also be distributed or affixed on the inner plane). Under no circumstance remove the weights affixed during stationary balancing. Mark the balancing weight required by electronic fine balancing using a prick punch in order to distinguish it.

Read out and erase the PSM fault memory after fine balancing.
