Sequential Manual Transmission System: Precaution

MAINTENANCE PRECAUTIONS
1. Confirm that the gear is in the N position before making the maintenance of the SMT system.
  If the gear can not be shifted into the N position (due to abnormalities of the system etc.):
  - Check that there is a hole of 7 mm (0.27 in.) in the vehicles rear side of the shift and select lever shaft of the transmission.
  - Then move the lever into the N position by inserting a screwdriver or something into the hole.
  - When the hole faces upward then as shown in the illustration, the gear is in the N position.
2. Be sure to follow the items bellow, before removing the SMT system.
  - Perform a cleaning of the connecting part of the SMT system hose and HPU, as there may be some dirt or foreign objects sticking to the part.
  - Reduce the pressure inside the accumulator to 0 bar (See PRE-CHECK ).
