  Tilt operating range (T)	: Refer to STEERING COLUMN : Service Data.
  Telescopic operating range (L)	: Refer to STEERING COLUMN : Service Data.

• Unlock the tilt and telescope adjustment lever, move steering column up and down smoothly without any catching or noise.

• After installation, turn steering wheel to make sure it moves smoothly while turning to the left and right stops.

• Make sure the number of turns is the same from the straight-forward position to left and right stops.

• Make sure that the steering wheel is in a neutral position when driving straight ahead.

• Rotate steering wheel to check for decentered condition, binding, noise, or excessive steering effort.

• Check the steering wheel play, neutral position steering wheel, steering wheel turning torque, and front wheel turning angle.
