  Torque: 50 N*m (510 kgf*cm, 37 ft.*lbf)
6. Turn the engine switch on (IG) so that power steering is available.
7. Turn the steering wheel 90 degrees to the right and check steering effort (torque) while turning. Check in the opposite direction using the same manner.
  Steering effort (Reference):
