MEMORY STORING
MEMORY STORING : DescriptionINFOID:0000000006248330
Always perform the memory storage when the battery terminal is disconnected or the driver seat control unit is
replaced. The memory function will not operate normally if no memory storage is performed.
MEMORY STORING : Special Repair RequirementINFOID:0000000006248331
Memory Storage Procedure
Two positions for the driver seat, steering column and outside mirror can be stored for memory operation by
following procedure.
1.STEP 1
Check the following conditions.
 Ignirion switch: ON
 A/T shift selector: P position
>> GO TO 2.
2.STEP 2
Adjust driver seat, steering colu mn and outside mirror position manually.
>> GO TO 3.
3.STEP 3
1. Push set switch. NOTE:
 Memory indicator for which driver seat position is already retained in memory is illuminated for 5 sec-
onds.
 Memory indicator for which driver seat position is not retained in memory is illuminated for 0.5 second.
2. Push the memory switch (1 or 2) for at least 1 second within 5 seconds after pushing the set switch.
NOTE:
 To enter driver seat positions into blank memo ry, memory indicator will be turned on for 5 seconds.
 To modify driver seat positions, memory indicato r will be turned OFF for 0.5 second, then turned ON for
5 seconds.
NOTE:
If memory is stored in the same memory switch, the previous memory will be deleted.
>> GO TO 4.
4.STEP 4
Confirm the operation of each part with memory operation.
