Precaution [08/2013 - 08/2016]

WARNING: This page is about a different variant/trim than selected.
  1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE BATTERY TERMINAL 
    NOTE:

    When disconnecting the cable from the negative (-) battery terminal, initialize the following system(s) after the cable is reconnected:

    System See Procedure
    Air Conditioning System (for Automatic Air Conditioning System) Refer to INITIALIZATION [08/2013 - 08/2015] Refer to INITIALIZATION [08/2015 - 08/2016]
  2. IGNITION SWITCH EXPRESSION 

    HINT: 

    The type of ignition switch used on this model differs depending on the specifications of the vehicle. The expressions listed in the table below are used in this section.

    Expression Ignition Switch (Position) Engine Switch (Condition)
    Ignition Switch off Off Off (Lock)
    Ignition Switch ON ON On (IG)
    Ignition Switch ACC ACC On (ACC)
    Engine Start START On (Start)
  3. PRECAUTION 
    NOTE:
    • Perform Reset Memory when replacing the Continuously Variable Transaxle (CVT) assembly or ECM.
    • Performing Reset Memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform Reset Memory, yaw rate and acceleration sensor zero point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table.

      Refer to INITIALIZATION [08/2013 - 08/2016] 

      Replaced Part
      • Continuously variable transaxle assembly
      • ECM
      • Oil pressure sensor
      • Airbag sensor assembly (Yaw rate and acceleration sensor)
  4. HANDLING PRECAUTIONS 
    WARNING:

    When using compressed air, always aim away from yourself to prevent CVT fluid from spraying on your face.

    NOTE:
    • Before removing components from the transaxle, clean off any sand, dirt or other foreign matter present on the exterior of the transaxle. Make sure that foreign matter does not contaminate the inside of the transaxle when parts are removed or installed, or during disassembly and reassembly of the transaxle.
    • When disassembling light alloy parts such as the case, do not pry them with a screwdriver or similar tool. Instead, tap the parts with a plastic hammer to separate them.
    • Do not wear cloth gloves or use cloth to handle parts during removal, disassembly, or installation of the transaxle. Instead, wear synthetic gloves to prevent cloth fiber from entering the transaxle.
    • Removed parts should be arranged in order and care should be taken to prevent dust contamination.
    • Apply Toyota Genuine CVT Fluid FE to all sliding surfaces and rotating parts.
    • Before installing O-rings and oil seal rings, coat them with Toyota Genuine CVT Fluid FE and be sure to not damage them.
    • Be careful to not damage the mating surfaces of components, because damage to these surfaces can cause oil leaks.
    • Before applying sealant, remove all of the old sealant and thoroughly clean the surfaces with non-residue solvent.
    • Use of Toyota Genuine CVT Fluid FE is recommended.
    • Do not subject parts such as sensors to any impacts. Replace parts with new ones if they are dropped or subjected to a severe blow.
