Note

After the engine switch is turned off, the radio receiver assembly records various types of memory and settings. As a result, after turning the engine switch off, be sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) battery terminal.

Waiting Time before Disconnecting Cable from Negative (-) Battery Terminal
System Name See Procedure
Vehicle enrolled in lexus enform system or safety connect system 6 minutes
Vehicle not enrolled in lexus enform system and safety connect system 1 minute

CAUTION:


  • B006FRZC22
    *a Heavy object exceeding the capacity of the engine lifter

    Because the weight of the engine with transmission assembly is extremely heavy, make sure to follow the work procedures described in the repair manual.

  • If work is not performed according to the procedures described in the repair manual, there is a danger that the engine lifter could drop and components could fall down.


  • B006CS7C12
    *a High temperature areas

    Do not touch the engine or exhaust manifold sub-assembly when they are hot.

  • Touching the engine or exhaust manifold sub-assembly when they are hot could result in burns.


  • B006GQB

    Never perform work on fuel system components near any possible ignition sources.

  • Vaporized fuel could ignite, resulting in a serious accident.


  • B006AN0

    Do not perform work on fuel system components without first disconnecting the cable from the negative (-) battery terminal.

  • Sparks could cause vaporized fuel to ignite, resulting in a serious accident.

Note

This procedure includes the removal of small-head bolts. Refer to Small-Head Bolts of Basic Repair Hint to identify the small-head bolts.
