Wheels, balancing on vehicle
Always deactivate the traction control system (ASR) before balancing the wheels.

Notes:
^ Incorrectly balanced wheels cause steering wheel vibration and shuddering at the front of the vehicle.
^ Where applicable, position the vehicle on the sensor platforms (front axle only for front-wheel drive, both axles for all-wheel drive) in order to carry out wheel balancing.
^ Check the manufacturer's instructions for operating any and all wheel balancing equipment.
